Access Value in CommandItemTemplate During NeedDataSource

[TallOne]

Hello All,

 I'm having problems accessing a value in the OnNeedDataSource event.  The value is a textbox in the CommandItemTemplate.  I'm using it as a custom filter while building the datasource.  I've done this before but forgot how I did it. :(  It seems that during the OnNeedDataSource the CommandItemTemplate has not been created yet. 

 

Thanks,
Jerry

Hi,

You can access textbox control placed in CommandItemTemplate on ItemCreated or PreRender server-side events of the grid. Try using the code snippet below and let me know about the result:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
  {
      if (e.Item.ItemType == GridItemType.CommandItem)
      {
          var textBox = (TextBox)e.Item.FindControl("TextBox1");
          // Your logic here
      }
  }

Additionally, I recommend you check out the article below which elaborates on accessing controls in RadGrid:
