[Solved] ItemCommand not firing

[John]

I have looked at probably all of the previous articles that return in a search fr this issue but none of them are quite like my problem so I am posting a new thread on it. In my thread found HERE , I was having an issue getting a new window to open using a GridButtonColumn. I used ItemCommand to get some data from my radgrid and store it in session. Then to open the new window I added the OnItemDataBound event. Once I added OnItemDataBound, the ItemCommand event no longer fires. If I remove OnItemDataBound, the ItemCommand even will fire again as expected. I need to have this functionality so it is my understanding that I need them both, any ideas?

it would appear that the code in the OnItemDataBound event is overwriting the default functionality of the GridButton. instead of firing the ItemCommand event as prescribed by default it is only firing the onClientClick. Anyone have a work-around?

Hi,

One suggestion is that you can pass the CommandArgument for the buttoncolumn as shown below.
C#:

protected void policeGrid_ItemCommand(object sender, GridCommandEventArgs e)
{
            if (e.CommandArgument == "Your argument")
            {
            }
}

Thanks,
Shinu
