Why Won't LinkButton Inside A GridView Raise Its OnClick Event
Feb 2, 2010
I have a LinkButton inside a GridView (via an TemplateField). No matter what I try, the LinkButton will not invoke its event handler. I have tried both traditional event handler ("OnClick")A OnRowCommand event handler at the GridView level.In both cases, I've debugged and it doesn't even catch the event handler.
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton Text="Cancel" ID="DeleteButton" CausesValidation="false" OnClick="CancelThis" runat="server" />

I need to generate a gridview with dynamic columns, on each cell I need a button that inserts-deletes a relationship in a database. The relationship is of course between what is represented by each column and row. I decided to use a gridview and create templatefields which I add programmatically to the table. I successfully got to that point but when i decided to raise a click event from the buttons or a rowcommand from the gridview I could not do it. I�m looking into doing this with button fields right now but I�m curious on how this can be accomplished?

How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)

<asp:LinkButton ID="LinkButtonNewServicesCategory" runat="server"
OnClientClick="this.disabled=true;return false;"
style="float:left;margin-right:5px;" CausesValidation="False">new services category</asp:LinkButton>
The intent is that when the LinkButton is clicked, it disables itself and returns false to prevent the postback (this control is used as a trigger for an animation).

What I'm trying to accomplish is to set my dynamically created linkbutton with a onClick command so when click it will run a method in the code behind. This is my code:
protected void Page_Init(object sender, EventArgs e)
LoadLeftSide();
private void LoadLeftSide()
{string filepath = Server.MapPath("DataSource.xml");
List<Post> list = PostHelper.GetAllPosts(filepath);

So, I have a MasterPage, in which I have an ImageButton and an UpdatePanel. Inside the UpdatePanel I have a LinkButton.
[Code]....
As you can see, both components are asociated to the same OnClick event, which should open said PDF document in a new window using javascript (Code Behind of the MasterPage):
[Code]....
I build the path using the toolTip of the component that has been clicked,which has the name of the file that should load in the
new window.
When I run the application, and click the ImageButton, the new window opens and the file loads correctly. However, when I click the LinkButton, nothing happens (it should do exactly the same as the ImageButton).
If I set a breakpoint, and debug, when I click the LinkButton, it goes to the LnkRelease1 event (as it should), everything looks fine, but it doesnt open the new window, It doesn't execute the javascript window.open.

I have two problems with a databound AJAX Accordion. The Accordion looks like this:
[Code]....
The code behind has this subroutine:
[Code]....
[Code]....
The first problem I'm having is that this subroutine is not fired (I have a breakpoint in it) when the LinkButton inside the accordion is clicked. The Page_Load event fires and there is no error message, javascript errors, etc, but nothing else happens.
The second problem is that I'm not sure how to go backwards with the databind. I want to be able to make use of the UpdateMethod in the ObjectDataSource because I also have textboxes inside the accordion. I will have a Save subroutine that can be called but I'm not sure what code to put inside it.

I have a ASP.NET Website, where, in a GridView item template, automatically populated by a LinqDataSource, there is a LinkButton defined as follows:

CommandArgument='<%# DataBinder.GetPropertyValue(GetDataItem(), "Id")%>'
OnCommand="removeVeto_OnClick"
OnClientClick='return confirm("Are you sure?");'

Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"

I am using the following code to load user control on to ASPX Page, which under a Master Page:
[Code]....
The user control name is passed as a parameter on the URL.
Inside the user, there is a LinkButton. The link button has a simple server side code for OnClick event.
Everything is working fine on the production machine, but, on the Development machine, I can see incorrect behaviour. I have started making some development changes on the Development Machine since several months back, and it will be very difficult to find out what caused the problem.
When I click the LinkButton inside the user control, the user control is removed from the parent page, and the OnClick event of the LinkButton is not firing.
I did debug, and found out that after I click on the LinkButton inside the user control, then the Page Load events for the master page and the ASPX page are working fine, and the IsPostBack is set to true, but the OnClick event of the LinkButton is not firing.

The following works just fine in Chrome.
<asp:LinkButton runat="server" ID="lbEdit" OnClick="lbEdit_Click">
<button type="button" class="edit">
Edit
</button>
</asp:LinkButton>
And here is the CSS for button and its subclass.
[code]...
As you can see, nothing special; just colors and beautiful things.
I click on the blue Edit button and it fires the OnClick postback just fine.... in Chrome! But if I do the same in IE8, it just does nothing; doesn't even detect a click.
I removed the tag and kept just the word "Edit", and it works just fine in IE8 as a simple underlined link; the postback fires.
So, Why can't IE8 accept anything within LinkButton?

I have created a master page for website layout in my project. I have used a linkbutton control to trigger between Login/Logout functionality but when I click on this control the underlying click event handler is not being executed anyway.When I click on this control, the page pointed by its PostBackUrl property is open which should probably occure after its click event hander have been executed.

and the LinkButton Control is

This is a weird issue. I have a List view with 2 Link buttons. "Edit" and "Delete" Iam able to attach an event handler for the first linkbutton(Update). Code in the event handler executed fine. But If I try to attach a event handler for the second link button(Delete) , I get an error.
My Item Template Looks like this.
[Code]....
First Item works absolutely fine. But If I attach the second handler, I get the following error
Am I missing some thing ? Note - There is no error if I try to attach the 1st event handler to the second link button.[ie EditLinkButtonClicked to DeleteLinkButtonClicked ] Issue occurs only when I try to attach DeleteLinkButtonClicked to DeleteLinkButton

I would like to call a method and pass a value to it on a link button autogenerated from the database in a templatefield inside a datagrid. I don't know much about delegates
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
..
((LinkButton)e.Row.Cells[(int)eMessage.TitleColumn].FindControl("btnMessageTitle")).Click += new EventHandler(delegate { viewSelectedMessage(this, 35); });
}
void viewSelectedMessage(object sender, int messageID)
{
lblTest.Text = messageID;
}
running the website and viewing the page source, I have realised that there is an OnClick event created for the linkbutton, however, this may be generated anyways. By running my solution using VS debugging, I can see that my method won't fire by clicking any of thos generated linkbuttons.

I have a gridview which is bound to a dataset. I have placed several template fields in the grid with the following type of setup
HTML Code:
<asp:TemplateField>
<HeaderTemplate>
<asp:Label ID="Label1" runat="server" Text="File"></asp:Label>
<asp:ImageButton AlternateText="ASC" ID="imgASC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/ASC.gif"
CommandArgument="eFolder ASC" runat="server" OnCommand="ImageButton_Command" />
<asp:ImageButton AlternateText="DESC" ID="imgDESC" Width="10" Height="10"
ImageUrl="~/Modules/Interface/DESC.gif"
CommandArgument="eFile DESC" runat="server" OnCommand="ImageButton_Command" />
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Eval("eFileName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
on the code page I have mapped the OnCommand event to the following code
Code:
Protected Sub ImageButton_Command(ByVal sender As Object, _
ByVal e As System.Web.UI.WebControls.CommandEventArgs)
Try
Dim img As ImageButton = CType(sender, ImageButton)
img.BorderStyle = BorderStyle.Ridge
SortOrder = e.CommandArgument
BindData()
Catch exc As Exception
ProcessModuleLoadException(Me, exc)
End Try
End Sub
My problem is that by clicking on the image button in the gridview header, the OnCommand event is not being fired. I have tried this with both OnClick and OnCommand and neither fires. I can't see what I am doing wrong if anything.
