Method is never called from dynamic button does anyone know why?

Question

Hello I create some dynamic LinkButtons in a grid that acts as a timebook the individual times - the buttons can be clicked and that should call the method (editGrid). I try to do this in the admin_pages.aspx.cs file. Creating a similar button from code in for example in the page load works fine. But it does not work in the method buildGui. Can anyone see why?

I suspect your problem is that you're calling buildGui from a button click handler rather than Page_Load. Dynamic controls will need to be recreated each time the page is loaded including on postbacks which currently will not be the case.

Yes that was it. I got it working by moving the creation of the buttons to page_load. Thank you.

That project in that zip file is big! Thank you for the small peice of code. That looks okay as far as I can see. I don't know what cell is though. I have a suggestion. I am not saying this to make a quick reply; this is actually what I would do. I would create a test project and I would try to create the smallest possible peice of code that reproduces the problem. Unfortunately that might not be practical in this situation since you cannot be certain that just because the test does not work that it is not working for the same reason. So another possibility is to copy the relevant portions of the actual project and then strip it down to the bare minimum that re-creates the problem. If you could just provide some guidance to what to look at in that big project then people are more likely to look at it.

Hi No answers yet and I still cannot understand this so here is some code. Hopefully someone can explain this to me what am i doing wrong? The user pushes a button and then I create an table and use the following code to add a button: LinkButton _button = new LinkButton(); DateTime buttonText = Convert.ToDateTime(dr.ItemArray[i].ToString()); _button.Text = buttonText.ToShortTimeString(); _button.ID = control_ + controlid++.ToString(); _button.CommandArgument = dr.ItemArray[i].ToString(); _button.Command += new CommandEventHandler(_button_Command); cell.Controls.Add(_button); As the user click on the linkbutton I want the _button_Command method to be called and it looks like this: public void _button_Command(object sender CommandEventArgs e) { int test = 0; } It is never called any ideas why?

I create the button and bind the click event in the method buildGui. That method is only called as the user pushes a button on my page.
