C# - Show Hide Using Javascript On A Control Inside A ASCX Control In A Gridview (ASP.NET + Javascript)
Oct 8, 2010
I have written a web usercontrol (ascx). Inside, there is a Panel that I want to show/hide on click of a hyperlink inside the usercontrol. Normally, this is easy just by doing something like this (the onclick attribute is added to the hyperlink on prerender):
I use a Repeater that's databound to a DataRowCollection and programatically build a table through that. I have something similar to: Private Sub SubAcctGrid_OnItemDataBound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs) If e.Item.ItemType = ListItemType.AlternatingItem Or e.Item.ItemType = ListItemType.Item Then Dim currentrow = TryCast(e.Item.DataItem, DataRow) Dim acctSummaryTable = New Table With {.ID = "acctSummary" & e.Item.ItemIndex, .CssClass = "minisub_acct_table"} [Code] .....
I can't pass in the correct element ID, though. From what I understand, ASP.NET transforms the ID I assign into some huge long ID for the sake of uniqueness. For example, I assign a table with the ID 'drillDownTable0' and it spits out 'ctl00_drillDownTable0' in the HTML markup. It worked the first time around, but then the Repeater gets binded to a new row and then I get 'ctl01_drillDownTable0' so on and so forth. I've tried the ClientID, ID, and UniqueID where I add the attributes to the Cells in the code above and they don't do what I need to. Is there any way I can get that ID and pass it to the Javascript function? Or I guess a better question is: When are the IDs generated and can I get to them before the page is rendered in HTML?
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):
I'm finding a dropdown in an ascxcontrol on my aspx in the following way.
Dim cp As ContentPlaceHolder = DirectCast(Page.Form.FindControl("ContentPlaceHolder1"), ContentPlaceHolder) Dim ascx As UserControl = DirectCast(cp.FindControl("drpType"), UserControl) Dim drpType As DropDownList = DirectCast(ascx.FindControl("drpType"), DropDownList)
Is there a faster way without having to acces all the elements on the page?
How to apply textbox blank validation on button click inside gridview in javascript?I have a gridview that contains 2 textboxes and a save button in each row.I want to validate the textboxes on corresponding save button click.
how can i call a VB function - deleteevent() in usercontrol.ascx.vb from a javascript function in clickhandler(e) in usercontrol.ascx. The call should cause a postback because I need the usercontrol to display the changes.I am currently trying to do it by using a linkbutton with style display:none, and calling its click event from the javascript function. But i dunno how to call the click event.
I need to focus on a textbox after an item has been selected from a dropdownlist.
I've tried control.focus() and setfocus(). The last thing I've tried was Set_Focus(dtbEffectiveDate.ClientID) inside the SelectedIndexChanged method with the folowing method.
I am developing an Outlook 2007 VSTO application that works with a commercial website.Almost all of the app's interactions with the website are done using HttpRequest objects.One user scenario does require the app to open a browser to a specific page on the site, and that page requires a Post string to provide the results of a form submit.I am using the version of the WebBrowser control that ships with VS 2008, and specifically VB.Net.My code successfully goes to the first page, after which it navigates to the actual target page (once the first page is loaded).That works, too, but if I click on the desired link on the target page, a JavaScript error pops up, stating "'j.parentNode' is not an object", with a Code of 0.I do not have access t the commerical site's internals. The page and links in question, when accessed via IE or Firefox, work correctly without the JavaScript error. The page containing the link is using Flex.Is this a problem with the nWebBrowser control?
i was able to set the name on the form on the page using.[code]ive found lots of ways to use the ID to select but nothing that will work with this javascript(i think it is)as there are no IDs, ive tried everything i could find.just to be clear, the is a webpage im loading into a vb.net 2010 app via the webbrowser control. im trying to change the selected index of the combobox in the webbrowser control to match what i have selected in a combobox control in the same application.
I'm having some issues finding examples of how to use the Awesomium web browser control in vb.net with objectforscripting. I know that objectforscripting isn't the same for the webcontrol used with awesomium since its HTML5 and not the traditional IE control that comes with vs 2010. The issue I'm having is finding any info/examples on how to communicate with the awesomium web browser control with my javascript. It's quite easy with the IE built in control with objectforscripting. I've found samples of how to do it in C# but I don't see any info of how I could do it just in VB. I've searched several things in google and I just can't seem to find anything on how to do it.So for example, I would have a button in a php page that the webcontrol browsers to and if I click the button it closes the application down. So I need to communicate using window.external with the webcontrol in VB.
I want to change the size of the images in javascript onmouseover.Dim files As String() = Directory.GetFiles(Server.MapPath("~/Folder1/Folder2/"), "*.jpg")
For Each File As String In files File = File.Substring(File.LastIndexOf("/") + 1, File.Length) 'Response.Write(File & "<br>") File = File & "~/Folder1/Folder2/"
I know how to InvokeScript so my VB form can call a javascript function in the Webbrowser document, but does anyoe know how to do it the other way round - ie javascript calling a vb function in the containing form? Why do I want to do this? Well I've got a table of telephone conversations. Some conversations are longer than others and they look silly in a grid with fixed row height. So I put them in an html document and display them in the webbrowser control. There's a hyperlink on each subject title, and I'd like the hyperlink to open an 'edit conversation' dialog box in my app.
Hello: i have javascript code for a popup calendar and works fine if a form is a form control: <form id="FormView1" runat="server">
however, if i use my formview control w/ the same code for a formview control, it doesn't put the value back into my text box txtDate after the user selects the date:
this seems to be the only difference so i was wondering if perhaps i need to reference this form in a different way? i don't know why it won't work for my formview control.

I am trying to pass a control's id to a javascript function that adds the value of it (the control which is a textbox) to a listbox but apparently I am not getting it right.
<input type="button" ID="btnAddtoLstBox" value="" title="Add this to the list" onclick="javascript:addToList(document.getElementById(btnAddtoLstBox));" class="ui-icon ui-icon-refresh ui-corner-all" style="width: 20px; height: 20px; background-position: -64px 80px" /> [Code] .....
An action that I'm trying to automatically complete on a web page requires me to click "Yes" on a JavaScript alert box. Obviously the entire process cannot be automated unless the program clicks "Yes" or "No" for the user. Is there any way that I can capture this alert box and click "Yes" programmatically?
I am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page. This works fine in IE 7 and Firefox.I then want to access this extra content in my program. Having found the HTML element containing the link, I tried element.InvokeMember("click"). I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link. I also tried setting the focus to the link element and using SendKeys to send the ENTER key, but all to no avail. Nothing seems to happen. I don't see the extra content produced by the JavaScript, nor do I get an error.Here is an extract from the HTML, showing the relevant (I hope) code:
If I use IE I can visit the website I want and click the 'Next' button and life is good. If I open that same website using the webBrowser control and click the 'Next button I get a javascript error message.I'm not doing anything in the code to manipulate the website. My goal, eventually, is to have some level of automation; but at this point, I get the javascript error and a pop-up and it screws everything else.

My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]
