The problem is my 'pcode' dropdownlist just works fine but in my 'fyyear' dropdownlist its just showing me values for the first entry only in the gridview like if a project is of two years then its showing me value for first date range lets say for ex 2010-2011 and when i am selecting 2011-2012 nothing is happening and it is automatically showing me the values for first entry only that is 2010-2011??

this is the query i am using on my submit button :
protected void Button2_Click(object sender, EventArgs e)
    {
        try
        {
 
       
        SqlDataAdapter da = new SqlDataAdapter("select pcode,fyyear,date,salary,ta,contigency,nrc,institcharges,others from monthly where pcode=('" + DropDownList1.SelectedItem.Text + "' ) AND fyyear=('" + DropDownList2.SelectedItem.Text + "')",con);
            DataTable dt = new DataTable();
            da.Fill(dt);
            GridView1.DataSource = dt;
            GridView1.DataBind();
        }
 
        catch (Exception ex)
        {
            ex.Message.ToString();
        }
    }
both fyyear and pcode are varchar

example pcode ICAR/40/34,Dst-23/101
fyyear 2010-2011, 2011-2012 and so on

did you populate dropdownlists on page_load from code behined?
If so this can be happen if these code are out side Ispostback checking
if(!Ispostback)
{
......
populate dropdownlist
......
}

public void Button2_Click(object sender, EventArgs e)
   {
       try
       {
 

           SqlDataAdapter da = new SqlDataAdapter("select pcode,fyyear,date,salary,ta,contigency,nrc,institcharges,others from monthly where pcode=('" + DropDownList1.SelectedItem.ToString() + "' ) AND fyyear=('" + DropDownList2.SelectedItem.ToString() + "')", con);
           DataTable dt = new DataTable();
           da.Fill(dt);
           GridView1.DataSource = dt;
           GridView1.DataBind();
 
           DropDownList1.SelectedIndex = 0;
           DropDownList2.SelectedIndex = 0;
       }
 
       catch (Exception ex)
       {
           ex.Message.ToString();
       }
 

   }
