Solution 1

This happens if you have used any source binding in your .aspx page. Try removing the data source which you have specified in design page and execute.

Do let me know if you still have any issues.

Thanks,
DRS

First of all remove

HTML

DataSourceID

from gridview from ASPX designer page.. :)

C#

protected void Button2_Click1(object sender, EventArgs e)
{
SqlConnection con = new SqlConnection(@"Data Source=ABHINAV-PC\ABHI;Initial Catalog=swapnil;Integrated Security=True");
con.Open();
if (DropDownList1.SelectedIndex == 0)
{

string SelectData="select * from Biscuits";
}
else if(DropDownList1.SelectedIndex == 1)
{
string SelectData="select * from oil";

}
SqlDataAdapter da = new SqlDataAdapter(SelectData,con);
DataTable dt = new DataTable ();
da.Fill(dt);
GridView1.DataSource = dt;
GridView1.DataBind();
