AJAX :: Trigger Event Added To Dynamic LinkButton Click Event?
Jun 25, 2010
I have searched around but unable to find a solution that will work. I have a link button that is created dynamically during the page load. It is given an ID (obviously). There is a script manager on the page. I have the controls added to a panel in the updatepanel (updatePanel1). There is a dynamic label that is also created with each link button. I can get a response from the linkbutton click event during a postback on the second time clicking the linkbutton, but I am getting a complete postback instead of the asyncpostback for that control. During the creation of the dynamic linkbuttons, I am also creating a dynamic trigger for each button and adding it to the updatePanel1. The Click event is not firing the method without doing a complete page postback.

I am working on an ASP.NET web application using .net 4.0 and VS2010.
I have a GridView and I am appending a row at the bottom to allow users to input data for "Adding" a new record.
The ONLY way I have found for this to work is to do this in the RowDataBound event of the grid. I can check to see if it is about to process the footer row then I know I am at the bottom and can insert this new row.
The row I am inserting contains a couple of TextBoxes and a LinkButton for the "Add" link.
If I just drop a LinkButton on my form and hook up the click event and I click the link button then the first thing that fires is the Page_Load event then my click event. However what is happening when I click the link button that was dynamically added to the GridView is the Page_Load event fires but the click event never does.
I have read 1000 threads saying to try to create the controls in the preinit() or some other event. In my case I can't. Or else someone would have to explain how to add the row to the bottom of the databound GridView.
Here is my code: (I removed creating the Textboxes because that is not part of the problem.

i am currently developing an asp.net project. there is a previous, next, and cancel button that the user can utilize, but the problem is that everything is broken into controls so that if they hit the browser's back button it will reset everything and take them to the very beginning. i would like to capture the onbeforeunload event and trigger the previous button click event (i.e. treating navigation like clicking the previous button).

I have made a popup that works within an update panel but what I can't get to work is that it calls the response.redirect to the home page right away instead of giving me the popup box. Is there a way to get around this. I insert my sql to the db, then call the popup but and then want to redirect to home page. but it automatically goes to home page is there a way to stop it until message is seen then redirect.

This event handler is not responding at all to the click event. On click, the pagination numbers disappear and I'm not able to trace it in the debugger because the event handle doesn't even fire so I have no idea what's going on.

I have a set of accordian divs (powered by the prototype library) in an asp.net page. I would like to save the state of the accordian, so when a postback event occurs, the same div is open rather than reloading the page entirely and opening the default div.
My plan was to set a page control value with the ID of the open div using the div's toggler click event function, and then fire a click event after postback calling that same div (using the value of the control holding the div ID) as the target. I'm not sure how to fire a javascript click event from vb.net however, and this sure seems like a lame workaround.
1) can you tell me how to fire a javascript click event from the vb.net codebehind page
-or-
2) is there a more elegant way to do this?

I have the following Hyperlink as a button:-
<asp:LinkButton ID="loginButton" runat="server" CssClass="loginButton" Text="LOGIN" OnClientClick="return validateLogin(memNoID,pwID)" AddressOf="loginButton.Click"></asp:LinkButton>
It causes a postback but only executes the onload and prerender sections of code. It totally ignores the following function signature:-
Protected Sub loginButton_Click(ByVal sender As Object, ByVal e As EventArgs)
Some code
End Sub

I have a LinkButton within a Datagrid. I am having trouble setting a Click event for it. I will add the OnClick="Remove_Click" attribute in the HTML. But when I go to write the actual event, VB isn't finding the LinkButton. Therefore nothing happens.
Here is the code for it.
<asp:DataGrid ID="StandardsDataGrid" runat="server" ShowHeader="false"
ShowFooter="false"
AutoGenerateColumns="false" CellPadding="2" CellSpacing="0"
ItemStyle-VerticalAlign="middle"
DataKeyField="Id" Width="100%" BorderColor="#000">
<Columns>
<asp:TemplateColumn>
<ItemTemplate>

I've placed a link button control on my web form and added the click event to the code behind automatically), but I've placed a break point and it never hits it. If I do the same thing with a button it works just fine.I've searched for this problem and none of the results seem to answer why mine isn't working. Maybe I'm just missing something?

I created a usercontrol I use to build up a list of at runtime. Each instance represent one category, and it will have a title, description and a button taking the user to the page displaying all articles for that category.
The control's members:
Code:
public string Title { get; set; }
public string Description { get; set; }
public int CategoryId { get; set; }
And the markup:
Code:
<h4><a href="#"><%=Title%></a></h4>
<div>
<p><%=Description%></p>
<p>
<br />
<asp:LinkButton CommandArgument="<%=CategoryId %>" runat="server"
CssClass="small btn red fr" onclick="LinkButton_Click">Go To <%=Title%></asp:LinkButton>
</p>
</div>
The code show's just fine, but the click even never fires when I click the button:
Code:
protected void LinkButton_Click(object sender, EventArgs e)
{
var x = sender as LinkButton;
string z = x.CommandArgument;
}
Obviously doing it wrong, but then, did not touch webforms in a long time.

My CompositeControl creates dinamically several RadioButtonLists according to the DataSource information. These controls are added to the Controls list and rendered in CreateChildControls event.
I need to create a LinkButton that clear a specific RadioButtonList selection and do a postback, to load the DataSource information again (some selections changes the data that need to be loaded from the database). For each RadioButtonList, I've put a LinkButton and assigned the Click Event to a method inside the same CompositeControl, to do the RadioButtonList cleaning.
Unfortunatelly, the LinkButton doesn't trigger the Click Event. In HTML code, the link has the "onclick" attribute setted with the asp.net event, but when clicked, nothing happens.

I dont know what happened but none of my buttons or linkbuttons causes a postback anymore. I have dragged a few updatepannels on the page but the linkbutton concerned is not enclosed within an update pannel. when I click it there is just no postback happening anymore. I set the debugger at Page_load but...its not reached. I used firebug to analyse the http requests. there is none. its like those are not considered buttons anymore.

I am adding numerical page links for paging of a repeater. I have used on of the numerical paging samples as my base. It works fine if I have less pages than my maximum total links. Eg if I have 11 pages, but only showing page 1-10 plus a next for the 11th, I get an error about duplicate control ids. I changed my control id to use a Guid in the string to keep it unque, after making this change the event handler never fires
private LinkButton createButton(string title, int index)
LinkButton lnk = new LinkButton();
//lnk.ID = System.Guid.NewGuid().ToString("N") + "_" + index.ToString();//Event does not fire if I set ID with Guid

I have a gridview where, when the user clicks the row, a modal form is shown and values are passed back to the calling function. This works just fine. However, now I have the requirement that instead of clicking the entire row, they want to just click a link button on the row (not the entire row) and get this same functionality. I am new to JQuery and cannot figure out how to select the link button inside the gridview in order to attach my function to it. Also, once I have that figured out, how do I get values from the Link Button's row to pass to my modal form? Here is my jquery function which works fine for the row-click:
$(document).ready(function() {
// set the background color of selected gridview row
$("#<%=gridResults.ClientID%> tr").click(function() {
$(this).css("background-color", "PowderBlue");
[Code].....
I would like to add a field like this to my gridview and attach the above functin to it:
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lnkCallModal" runat="server" CausesValidation="False" CommandName="linkPol"
Text="Modal Search" >
</asp:LinkButton>
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" Width="10px" />
</asp:TemplateField>
