Question

How can I set ID to TabelRows generated by DataGrid/DataList?
I want to assign a row id by myself to every row of DataList.

Answer 1

Attach a handler for the ItemDataBound event on your control:

<asp:DataGrid OnItemDataBound="myGrid_ItemDataBound" ...>

Declare the handler method like this:

protected void myGrid_ItemDataBound(object sender, DataGridItemEventArgs e)
{
    e.Item.Attributes.Add("id", "some_id");
}
