克里希纳，

您必须设置属性

Hi krishna,

you have to set the property

GridView.EmptyDataText = "No Record". 

如果您没有记录

if you have no record

在您的代码中进行一些小的修改

In ur code just make a small modification

protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e)
    {
        if (e.AffectedRows == 0)
        {
            //Label1.Text = "Hai Krishna";
            LabelNoRecord.Visible=True;
            LabelNoRecord.Text = "No Record Found";

        }
       else
        {
        LabelNoRecord.Visible=False;

        }


    }
