Hello,

Please use prerender event in-place of itemdatabound event.

protected void RadGrid1_PreRender(object sender, EventArgs e)
    {
        foreach (GridDataItem item in RadGrid1.MasterTableView.Items)
        {
            //Acceess parent Item
           // Access parent button here set  visibility
            if (item.HasChildItems)
            {
                foreach (GridDataItem citem in item.ChildItem.NestedTableViews[0].Items)
                {
                    //Access child item
                   // Access child button here set  visibility
                }
            }
        }
    }

Hi Rahul,
Please try the below code snippet to hide the GridEditCommandColumn.

C#:

protected void RadGrid1_PreRender2(object sender, EventArgs e)

      {

          foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

          {

             //Your Condition

              {

                  LinkButton linkParent = (LinkButton)item["GridEditCommandColumn1"].Controls[0];// Access the parent GridEditCommandColumn


                  linkParent .Visible = false;           

                  if (item.HasChildItems)

                  {

                      foreach (GridDataItem childitem in item.ChildItem.NestedTableViews[0].Items)

                      {

                          LinkButton linkChild= (LinkButton)childitem ["GridEditCommandColumn"].Controls[0];//Access the child GridEditCommandColumn

                          linkChild.Visible = false;                          

                      }

                  }

              }

          }
