On Image Button, Add a Event handler for with Command Argument as the Set Number or whatever. That you can take and pass a bind expression in gridview.

Use datakey name on the gridview property
Use query string for retrieving ID

You can also try this method
private void GridView1_Cell_Click(object sender, GridViewCellEventArgs e)
{
int cellindex=e.CellIndex;
int rowindex =e.rowindex;
var value = GridView1.Rows[rowindex].Cells[cellindex].value;

}
