I have a asp:textbox inside an AJAX updatepanel. My goal is to be able to update other controls, such as a asp:listbox that is inside the same updatepanel, while I type in the asp:textbox. I can easily do this using javascript. However, I am under a restriction, that is, I cannot use javascript.
View 1 RepliesI've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server.This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page.The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.
Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments.
So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.
The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it?
edit:Im adding some code because im still confused with this
Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
[code]....
This method gets called on a click of a button... The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:
<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />
So why is this property always returning false?
I have an asp.net gridview that is originally bound to a sqldatasource control, but when the user presses an external button, it instead gets the contents of a datatable rather than a SQLdatasource control. I therefore had to write code in the PageIndexChanging event of the gridview to allow for paging. My code is as follows:
Protected Sub gvEvents_PageIndexChanging(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewPageEventArgs) Handles gvEvents.PageIndexChanging
gvEvents.PageIndex = e.NewPageIndex
gvEvents.DataBind()
This worked beautifully until I added an AJAX update panel so the whole page wouldn't postback every time it paged, and paging stopped working. I debugged it and discovered that it is actually calling the PageIndexChanging event, but nothing is happening. I searched the web and found a few people with the same problem, but their solutions did not work for me. There was one on this site whose problem was solved by the following:
In PageIndexchanging event, where you bind data to grid, make sure, data is again fetched from the DB
I don't know what that means; my data was being bound as demonstrated above. I have "enable paging" set to true and EnableSortingAndPagingCallbacks set to false.
I am including my markup for the updatepanel below.
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ibtnSearch" />
</Triggers>
[CODE]...
I'm creating a number of textboxes, all calling a function during the onchange event to update their value to the database. These boxes are dynamically created in the backend because the data changes based on specific criteria that can be changed on the page. Here's the creation of the boxes:
Dim t as TableRow
tC = New TableCell
Dim txtBox As New TextBox
[Code]....
When I enter a number into the Textbox, the event fires as expected, but it fires twice.
Listen I'm very new to MVC 3.0 but I've been looking and looking for a simple straight forward tutorial for replacing an asp:UpdatePanel in the MVC world. There are lots of examples on the jquery function that needs to be called but since I don't know how to wire it up in MVC I'm still lost. Can someone point me to a hard and fast example on how I can do a simple "timer refreshed" partial view such as putting the date time on a _layout.vbhtml page?
View 2 RepliesI have a label inside an update panel which I wouldl ike to use as a status bar.Basically the user clicks a button which executes a main fucntion that performs a series of tasks. I'd like to inform the user as to the state of the function as it progresses e.g.:
Stage 1: Retrieving data...
Stage 2: Calculating values...
Stage 3: Printing values...
Stage 4: Done!
I've tried updating the updatepanel directly from the function but it only updates the panel at the end of function (stage 4) and shows "Done!" (which I understand is how it should work).I've been looking into timers and threads to try and update the panel separate to the main function?
I have a page that takes a while to load between partial post backs and have placed a UpdatePanelAnimationExtender to fade the updatepanel in and out. Sample:
Aspx
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" >
<ContentTemplate>
[code]....
And it does the fade in and out correctly. If you take the URL with history information and try to load it in a new tab the Button 12 displays correctly but it remains faded out. I had heard people say the OnUpdated will only run if a partialpostback has occured in reference to the page loading the first time. I am guessing it is not faking partialpostback when loading by history so it never gets faded in.
A little pseudo code to provide some background:I have an ASPX with a placeholder and a buttonWhen the button is clicked it adds a web user control (uc1) to my placeholderThe uc has a button

I have a UserControl inside UpdatePanel, how to update the user control when clicking a button
View 1 RepliesI'm trying to speed up my Repeater so that not as much HTML has to be resent via the AJAX UpdatePanel on each call.
So here's what I have (a very much simplified version):
<asp:Repeater ID="rptContactSteps" runat="server">
<ItemTemplate>
<p>Script:<br /><%#mobjSDIT.FormatText(Eval("script"))%></p>
[Code]....
So, when I click 'btnSaveAndCompleteLastStep' I want all the UpdatePanel in 'rptContactSteps' to update. Having the UpdatePanel inside the ItemTemplate should help prevent having to re-load the html/text that populates the Eval("script") & Eval("notes"), since the value of these variables could be very large and over a 3G connection this could be very costly (in time & money).
I though by adding the async trigger it'd work as I have used this type of trigger before, but not when inside the Repeater. Currently the UpdatePanels aren't getting updated at all, except from the one from which the button was pressed.
I am having trouble binding data to data repeater when I use ISyncResult.This is what I am doing.There is a button inside a Update Panel that gets the input from the user and calls a function that returns a dataset that I then bind to data repeater which is also inside a update panel.What I did is that I made a delegate to this function, now I am calling this function like this
[Code]...
I am having hard time figuring out why the data repeater is showing no data.While debugging this I see that the dataset is getting the data and is passing the the "ds" but nothing is showing up on my page even though the data is being passed to controls inside data repeater while I am debugging.
I have a GridView which is continually rebound using a timer and is within an updatePanel so the page doesn't refresh continually (each row has a countdown sequence so the gridview needs to continually get updated). Inside the gridview i have an imagebutton with an OnClick method. Previously to get the OnClick method to fire I would make sure the gridView wasn't in an UpdatePanel and that the pageload databinding of the gridview was in an "If Not IsPostBack". With the Timer though I can't have the gridview binding an an "If Not IsPostBack" and it needs to be in an UpdatePanel. Is there a way to use an UpdatePanel and "If Not IsPostBack" and still get the OnClick method to be called?
Here's some of the code, if my explanation didn't make complete sense:
UpdatePanel/Timer/GridView
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:Timer ID="timerCountDown" runat="server" Interval="1000" OnTick="timerCountDown_Tick"></asp:Timer>

Description of problem: I have an updatepanel that works fine in all browsers in a simple frame layout.
When I include jquery-1.7.1.min.js [URL].. on my page it breaks the updatepanel such that any control no longer does a partial postback - but instead does a full post-back, this behaviour only seems to happen in internet explorer (tested only in ie8 so far).
[Code]...
You can confirm that the update panel works nicely by changing the background colour and clicking dates on the calendar, by opening pdhtest.aspx. the frame-set should break this behaviour for internet explorer 8.

I'm trying to execute some javascript code on my UpdatePanel's OnLoad event like so:
<asp:UpdatePanel ID="updDropDowns" runat="server" OnLoad="javascript:ResetButtons();">
But I keep getting "'javascript' is not a member of ASP.reasons_aspx".
I tried doing
Me.updDropDowns.Attributes.Add("OnLoad", "javascript:ResetButtons();")
But I can't reference the 'Attributes' property of an UpdatePanel in the VB code-behind.
However, I recently tried to use it in a repeater. Essentially my company wants to have a number of different values displayed as the main repeater (no problem setting that up). When the user clicks on a field within that repeater, they would like the collapsible panel to open up and display the detail information for that piece of data. The details are within a sub repeater.The repeater functionality and the child repeater functionality are working perfectly. So the repeater and the child repeater aren't the issue. If I take the collapsible panel extender out the data displays perfectly.The problem is that once I start opening and closing the panels, the screen rendering starts to go crazy, and there seems to be no rhyme or reason for it.
For example, on the initial screen rendering I get seven entries. They look perfect. Each of the seven line up across the screen and no extraneous data is shown.I click to open the first row, and it displays great. No problem. But when I then click it again to close the first row, I only see the first four rows of data, then a huge white space with a few seemingly random characters, then the next 2 rows, a smaller whitespace, then the seventh row. I click to open the first row again and everything looks exactly as it should again. Again close, again 4 rows, whitespace, 2 rows whitespace, last row.I reload the page and everything is ok.
So now I click on the second row to open it and everything looks perfect. I close the second row and I get the exact same result.Has anyone ever tried to use the ajax collapsible panel inside a repeater? If so, have you encountered strange rendering behavior such as this? And if so, were you able to get it to work?Here's a stripped down version of the

I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:
<asp:Timer ID="Timer1" OnTick="Timer1_Tick" runat="server" Interval="10000"></asp:Timer>
<asp:updatepanel id="upParent" runat="server" UpdateMode="Conditional">

My code behind is VB.NET. I use ASP.NET UpdatePanel like the following. However, after the post-back, it locks TextBox controls , I cannot type anything, except when I move the mouse over and click on the TextBox.
why it locked all TextBox controls after the post-back?
Here's why I use UpdatePanel:
During the post-back, after inserting data into DB, set all TextBox text property to String.Empty After the form is submitted, the Panel pStudent should be refresh , not the entire page and the TextBox txtId should be in focus again.
here's the mark-up of the ASP.NET page: [URL]
I am trying to implement an update panel on my web page. when I add this, everything works fine:
<script runat="server">

Me.Label2.Text = Date.Now.ToString

This will cause the event to not occur. If i change the "<" from the string, all is well. why cant I have "<" in my strings? This is important because i wont allow me to put an xml string in the text box.
For several days now I've been messing around with Ajax calls using different combinations of javascript, ASP controls, and regular controls. I've gotten a bit of understanding about what's going on, but using ASP controls still hides too much of the machinery, and I want to have a deeper understanding. With that aim, can anyone tell me why the following setup doesn't quite work?I have a file "Testy.aspx" with the following:[code].....
So, I hoped to make my .aspx file do double-duty both as the regular-page request handler as well as the Ajax request handler. However, when I click the button ("baroo") to generate the Ajax request, the result that ends up written back to the "testytext" div is the raw html for the entire page, as if under normal request conditions. Clearly, my attempt to override the page request by making the code-behind implement IHttpHandler and supplying an "Overrides Sub ProcessRequest" method is not working. The server is still treating the Ajax request as a normal request, and in fact my own "ProcessRequest" method is never even called.Is it possible to build a page/handler like this? How can I intercept the incoming request from the client and respond accordingly?This is how Ajax works, right? So it must be possible.Again, I'm deliberately doing this as an excercise to avoid the use of "magic" ASP controls like UpdatePanels,
So, I have a textbox with the following text.
Code:
TITLE"Hello there"
blah blah blah etc...
I want my program to find the TITLE text, and then put the text in the double quotations in a variable.
I have a DataList inside another DataList. I want to access the child DataList "dlQuestion" events, ItemDataBound event. Also, I'm tring to find the control LableControl "lblQuestion" in the child datalist. How do I do that? Here's the mark-up:
<asp:DataList ID="dlSection" runat="server" Width="100%">
<ItemTemplate>
<div>

Im sure this is a very simple and easy to answer question but I've been looking at this too long and being new to ASP I cant seem to find a solution that works.
I have an ASP calendar extender, I click it and the calendar displays as expected, the selected date appears in the textbox, but when the page then posts back I cant get the selected date value from either the textbox.text or the calendarextender.selecteddate properties, I tested this by trying to assign these values to a string variable in the page_load event.

So basically I have a ComboBox on a form, which I populated by adding custom object named "Category" and by setting the DisplayMember to the property "Name" of my object.On another form that can be opened at the same time, I can edit the name of theses "Category" objects.

Even if the property "Name" of the object "Category" change, the display on the ComboBox doesn't autoupdate. So I need to catch the event, but I don't know how to do it.
