I get an error when attempting to navigate to the page containing this gridview. The error is
'SelectPackage_Click' is not a member of 'ASP.offer_aspx'.
here my page directive:

Here is my markup. Eventhough SelectPackage_Click is present in the code behind, it is not wired up with the button control.

i want to find a row of my button click and there i can call my method.
I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.
I got an event handler like this, in this event, i wanted to call another button click event. How can I do that?
[Code]....
if (ds.Tables[0].Rows.Count == 0)
I put it down for a few weeks to work on other things, but started working on it again because I need to get it to work.
Anyway, I figured if I wanted to put a button in a datalist all I had to do was:
[Code]....
And then in code behind:
protected void datalist1_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName == "submit")
{
// code here
}
}
This is what everyone else says to do when I search google. I put a break on the event but the event never fires. Does it matter if I am using VS 2010 and .net 4.0?
Is there a technical reason for the existence of Page.PreLoad or is this just convenience to have a place where you can neatly place code that always have to be executed before the Load code? Is there a difference between adding code in the PreLoad event handler and adding code at the top of the Load event handler? And what would be a typical scenario where you use PreLoad?

In VS, I can't select the button and see my list of available events in the properties window like is normally done for controls outside of templates like this... what do I need to do?

I want to add an event handeler that tell me wich row had been selected and highlighted it too. I tried many times, but usually face this error "No overload for 'Grd_ServersInfo_CheckSelectedRow' matches delegate 'System.EventHandler' ". Could any one paste the right code lines to handel this event
I'm creating a GridView in code. I can successfully attach handlers for Editing, and CancelEditing. RowUpdating never runs, however. Instead, if the GridView is in a Panel, the Edit handler is called when Update is clicked (and this is the command name I get back on the Update click, too). If the GridView is not in a panel, then the Cancel handler is called when Update is clicked (again, this is the command name I get back from clicking Update). I've searched high and low for a reason why the RowUpdating event is not getting called, and I can't find one. Does anyone out there haveHere is my code (My actual code is much more involved than this, but for testing purposes, I extracted the following code and stuck it in a new project to isolate my problem):
protected void Page_Init(object sender, EventArgs e)

I am trying to create a custom GridView with a header toolbar at the top that will contain icons to export the grid view to different formats like excel, word, etc.. The problem is, I cannot get the method to fire that is assigned to handle the click event for the corresponding Image Button. The page posts back, but the code I have in the method to handle the click event does not fire. I have followed examples in other posts and from what I can tell I have followed what others have done. Can somebody take a look at see if they can find something that I am doing wrong.

I have a asp:button in template field of gridview, I set command name for this and in grid I mention on command event. On clicking the page it shows error message is :
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
Below is my code
<asp:GridView runat="server" ID="gridManageClients" AutoGenerateColumns="False" OnRowCommand="gridRowCommand">
