Get ID of item in ASP.NET Listview on button click

Question

I have a button on each row of a listview. I have a method on the click event in which I would like to get the ID of the data item. I placed a `hidden field` in the list view to store the ID. However, ``` ListView1.FindControl("hiddenField") is returning null. ``` I have tried several different event args, but only the blank event args is working with this button, so I don't have anything in the event args. I tried to set the command of the button to call commandEventArgs, but no matter what event args I use besides "eventArgs" I get: No overload for 'btnManage_Click' matches delegate 'System.EventHandler' How do I get the event args into this button? EDIT Button is in ItemTemplate section of following ListView ```

Accepted Answer

You can use like this ``` ``` Check out the API http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listviewcommandeventargs.aspx If you have a button then simply ``` protected void templateButton_OnClick(object sender, EventArgs e) { Button myButton = (Button)sender; } ``` More details http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.listview.itemcommand.aspx Edit 1 Suppose that you have a property "id" then you can use like this ``` CommandArgument='<%#Eval("id")' ``` Edit 2 As it is case sensitive and you have ``` DataKeyNames="Id" ``` So you should use as follows ``` CommandArgument='<%#Eval("Id")' ``` and use it like follows ``` int i = Convert.ToInt32(myButton.CommandArgument.ToString()); ```
