About GridView 's key fields

[marss]

Suppose I define a key field for GridView as is shown below.

GridView1.DataKeyNames = new string[] { "EntityId" };
GridView1.DataSource = ... //some data source
GridView1.DataBind();

Is there any way to find a gridview row by EntityId if data already
has been bound for GridView1? I mean I have, for example, a button on
a page and I want to find a gridview row by a known key field value
within this button's click event handler.

Thanks

Or maybe you can do this. Assign the Container.DataItemIndex to the
CommandArgument property of your Button in the GridView, and then in
your RowCommand event handler , you can say:

protected void GridView1_RowCommand(object s, GridViewCommandEventArgs
e)
{
if
(((GridView1.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString()).Equals("EntityID")))
{
Label1.Text = "The row index is " + e.CommangArgument;
}
}

Thanks for answer.

It is not exactly what I am looking for. When I said "button" I did
not mean a button in the gridview but I mean a button on a page that
is not attached to an appointed EntityId. The problem is how to find a
gridview row by known (or calculated or extracted from a database)
EntityId in any event handler that occurs after data has been bound.
Using gridview key fields.
