Gridview click on header for sorting triggering row command

Question

I have a fairly simple GridView. This is the markup for Columns: ``` ``` However, when I click on of the columns for sorting, it first triggers a row command event and then comes to sorting event. Can anybody tell me…

Accepted Answer

`Sort` is a `row command`. Check out this MSDN GridView.RowCommand Event article for more details.

In your row command event you should add an `if` statement so you can determine when the row command code should execute. Use e.CommandName.

```
void ContactsGridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
  // If multiple buttons are used in a GridView control, use the
  // CommandName property to determine which button was clicked.
  if(e.CommandName=="Add")
  {
    // Convert the row index stored in the CommandArgument
    // property to an Integer.
    int index = Convert.ToInt32(e.CommandArgument);

// Retrieve the row that contains the button clicked 
    // by the user from the Rows collection.
    GridViewRow row = ContactsGridView.Rows[index];

// Create a new ListItem object for the contact in the row.     
    ListItem item = new ListItem();
    item.Text = Server.HtmlDecode(row.Cells[2].Text) + " " +
    Server.HtmlDecode(row.Cells[3].Text);

// If the contact is not already in the ListBox, add the ListItem 
    // object to the Items collection of the ListBox control. 
    if (!ContactsListBox.Items.Contains(item))
    {
      ContactsListBox.Items.Add(item);
    }
  }
}  
```
