Javascript - Update Page After GridView DataBind?
Sep 27, 2011
Apparently, part of the problem is that while an ASP:GridView has an OnDataBound() event (which you can use in the code-behind), the corresponding HTML table that is produced does NOT, so you can attach that event to JavaScript. (Did I get that right?) So, that's why I'm having trouble with that bit of the issue. Back to the drawing board. I'm a desktop developer (WinForms with VB.NET) transitioning into ASP.NET development. My mind is really bending around the DOM and JavaScript and Session State and all of the stuff that goes along with web development. I'm not stupid, and I've done research (including hours of video watching and hundreds of pages of "Intro to ASP.NET" reading), but I keep hitting the wall with what seem to be fairly straightforward problems.
Basically, my current situation can be summed up as follows:
I have a page that runs a very long process initiated by the user. The long process can take up to a few minutes , so I want to indicate to the user that SOMETHING is happening.When the process has completed, I either have:
a. Results to show in a GridView
b. No results to show
If I have results to show, I want to display them. If I have no results to show, I want to show a label to the user that says "No results to show."

Please can you translate the above line of C# into VB.NET?At runtime, I'm trying to update an existing GridView column, as opposed to adding new columns, just before a DataBind()

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

I've got a gridview (ASP.net) inside of an update panel. I also have a "Save" button so that when I click "Save" it loops through all the rows of a grid view and passes the data to a stored procedure to update each row. This was too slow as sometimes I would be updating the database even though a change did not occur.
I decided to add a field in my gridview like so:
<asp:TemplateField>
<ItemTemplate>
<input type="hidden" id="hdnIsChanged" runat="server" />

Is there a way to trigger a GridView rebind from an html markup page using jQuery or jscript?
I have an ActiveX download control which passes all events via jscript.
So, a have a download complete event on the markup page but not the code behind.

I have aspx gridview with checkbox on evryrow, what is required is whenever we check any of the rows, a query should be launched to change the specific agent -each row consist of agentID, Pass, Status- to Paid Status. using javascriptWhat I need to know is how to loop to get the Checked row and get the ID of the row checked so that I can get THe ID of the Agent in thos row so that I can update its status.using javascriptI found something similar on stackflow:t GridView selected row DataKey in JavascriptBut it is not my case, what is needed is at the check of a checkbox a javascript function should launch through which I could update the selected row in grid view after having the index of this row and this all to avoid refreshing the page.

How do I print the page title and the header of a GridView on each print page?
I want to add page title and GridView heading on each page.
I used page break to break the GridView into multiple pages, but only the first page comes with title and all other are without header and title page.
For a dynamic GridView, my code uses AutoGenerateColumns="true".

I have a DataAccessLayer that returns a datatable. The business layer calling it also returns a type datatable.In my form, I call the business layer as a datasource of my gridview and then I binded it.
This codes are working in C# but I have problems when I converted it to VB.NET. During databind it displays the error: Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.
Can i not bind a datatable in my gridview in vb.net? What do you think is the problem?

I have a GridView on an ASP.NET page that I'm trying to bind to an object data source that I've set up to map to a vb object I made which accesses the DB. When I run the page, though, the gridview comes up empty.
The ObjectDataSource is definitely returning data. The paging parameters are making it to the underlying object. All the way until I get to the DataBind() call everything seems fine. But the grid comes up empty. Funny thing is, if I use the method that returns all records in the DB, the grid populates just fine. Only when I try to implement custom paging does display no records. I've tried using the wizards, I've tried diagrammatically setting it up and run time. No matter what I do I can't get paged data to display in the grid.
oDatasource = New ObjectDataSource()
oDatasource.EnablePaging = True
oDatasource.TypeName = "tblMessage"
oDatasource.SelectMethod = "GetTblMessageSubset"

I am databinding my gridview in VB code behind. Because of this I know I can not refer to the NewValues when text is entered into one of the edit boxes. I need to retrieve the value of a column in the RowUpdating event.I have tried to do this in a multide of ways, but each of my changes ends up breaking something else.None of these three methods is working....
Dim DT34 As String = DirectCast(GridView4.Rows.FindControl("Textbox1"), TextBox).Text
Dim TB1 As Label = GridView4.Rows(e.NewEditIndex).Cells(0).FindControl("Label1")
Dim tb1 As TextBox = GridView4.Rows(e.RowIndex).Cells(0).FindControl("TextBox1")
Dim IDVal As String = tb1.Text
In the following code, I am believe it is finding the control but it is not returning the value that was entered into the textbox.
Dim tb As TextBox = DirectCast(GRD4.Rows(index1).FindControl("TextBox1"), TextBox)
updateDescription = tb.Text
My field has been converted to a Template field in the Gridview instead of Boundfield.

I have a function that returns a list of account numbers as an Arraylist. I am trying to use each account as a command parameter in another sub routine to get more data about each account number. This only returns the data for the last account number in the arraylist. I need to use each account number, call the database, get the additional information and store ALL of the data into a Gridview (databind). Example: If I had 3 account numbers in my arraylist return 3 rows of data to the gridview. I am struggling with how to get ALL of the information for each value (account number) in the Arraylist. Can someone point me in the right direction?? I think this can be done but I am not certain if my approach is correct or not. Perhaps I need to create datatables that contain the additional information for each value passed via the arraylist.

I have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

I'm experiencing a problem when clicking on the page number within my ASP .NET gridview. When I click another page number, I am redirected to another unrelated page within my project.This wasn't a problem until I added jQuery to my masterpage, so I'm guessing there is some sort of conflict in the javascript code. When the aforementioned redirect happens, the page PageIndexChanging event isn't fired and there isn't a postback as far as I can tell. [code]

I have a gridview that is set to a sql datasource, it is generating the columns automatically. If I add a column to the table it is referencing, it will draw that column and display it, but it does not update the insert/update commands to include the new column. Is there any way have it rebuild those commands automatically?

how i can get the grid to select a row by clicking on any cell in the row?
The only way i can do this at the moment is by setting the AutoGenerateSelectButton property to True, but this adds a column to the grid with a crude "select" hyperlink and only selects the row if the word "Select" is cliked on.

Basically what needs to happen is when the user clicks edit onto the gridview and clicks on a certain textbox a javascript calendar popups up and the user picks a date.So far, I can set it statically and the calendar works for that one row, but not the other rows since the ID changes.My ASP Code (id of textbox has been set to txtStartDate):
<asp:TemplateField SortExpression="StartDate" HeaderText="Start Date">
<EditItemTemplate>
<asp:TextBox ID="txtStartDate" onClick="ddlchange()" Runat="server" Text='<%#Bind("StartDate")%>'>
[code]....
This works, for one textbox. It does not work for other since 'ct102' changes with every row.
