How do I programmatically add a button to a gridview and assign it to a specific code-behind function?

Question

In runtime I\'m creating a DataTable and using nested for-loops to populate the table. This table I later assign as DataSource to a gridview and on RowDataBound I assign the

On your gridview in markup, assign CommandArgument attribute to whichever you want (here I choose the index of the current gridviewrow) inside the your buttons.

Or in your code behind, you can create a button like below

protected void GridViewDice_RowDataBound(object sender, GridViewRowEventArgs e) 
{ 


    DataTable diceTable = _gm.GetDice(_gameId); 
    for (int i = 0; i < GameRules.ColumnsOfDice; i++) 
    { 
        if(e.Row.RowIndex > -1) 
        { 
            Button btn = new Button();
            btn.CommandArgument = diceTable.Rows[e.Row.RowIndex][i].ToString(); 
            btn.Attributes.Add("OnClick", "btn_Clicked");

            e.Row.Cells[i].Controls.Add(btn);
        }
    }
}

then make an event handler like below

protected void btn_Clicked(object sender, EventAgrs e)
{
   //get your command argument from the button here
   if (sender is Button)
   {
     try
     {
        String yourAssignedValue = ((Button)sender).CommandArgument;
     }
     catch
     {
       //Check for exception
     }
   }
}
