I was trying to get the data item in SelectedIndexChanged.  Here is what I have:

    protected void Grid1_SelectedIndexChanged(object sender, System.EventArgs e)  
    {  
          
        GridItem item = Grid1.SelectedItems[0] as GridItem;  
        Customer cust = item.DataItem as Customer;  
    }  

where Customer is my data type for data binding.  The item object in the above codes is null.  Please help.  Thanks,

Peichung

Hi Peichung,

I have read in the forums that the DataItem is null after post-back - this object is available only during data-binding. i.e when used in data bound context (inside the ItemDataBound handler of the grid). You may go through the following forum discussion for more details.
dataitem is null

Hi Shinu,

Thank you for pointing this out.  I guess wasn't thinking clearly when I tried to get the DataItem.  It makes sense to not have DataItem available after data bind.  I access the grid item instead:


GridDataItem item = Grid1.SelectedItems[0] as GridDataItem;  
string s = item["CustomerName"].Text; 



Thank you.
