Hi Arti,
its very simple to bind the gridview based ont the value u have selected in the combobox.
In the SelectedIndexChangedEvent() of your combobox, write your SQL Query to bind the gridview.
For e.g.
protected void ComboBox_SelectedIndexChanged(object o, xSelectedIndexChangedEventArgs e)
{
int Value=Convert.ToInt32(ComboBox.SelectedValue);
}
I hope it will help.
If any query, pls revert back to me.
