One of the gridview columns contains a button, with additional columns being added to the gridview via code behind. The click event is attached using the following line of code:
cmd1.OnClientClick += new EventHandler(cmd1_Click);However, upon clicking the button, a runtime error occurs and breaks at System.EventHandler of
<input type="submit" name="grvList$ctl02$ctl05" value="Add" onclick="System.EventHandler;" />Has anyone encountered this issue before?
According to user1090190's comment, when the onclick event is triggered (created by OnClientClick), it is run as JavaScript in the web browser.
In this scenario, the += operation is invoking the ToString() method on the new EventHandler object, resulting in the string value of "System.EventHandler". This conversion occurs because OnClientClick is treated as a string. The expression
cmd1.OnClientClick = cmd1.OnClientClick + (new EventHandler(cmd1_Click));+= functionality.
It would be better written without the word Client:
cmd1.Click += new EventHandler(cmd1_Click)
Alternatively, a simpler way to write it is:
cmd1.Click += cmd1_Click;
Ensure that this handler is established for each postback as needed.
Enjoy coding!
