[Naik Dhiren]

I have a one textbox on the form and combo1 in datagridview
when form is load combo1 is empty
if value of text1.text is 'A'
then combo1 should have below items.
combo1.Items.Clear();
combo1.Items.Add("Director");
combo1.Items.Add("MD");
combo1.Items.Add("President");
combo1.Items.Add("Chairman");
combo1.Items.Add("FullTimeDir");
and
if value of text1.text is 'B' then combo1 should have below values.
combo1.Items.Clear();
combo1.Items.Add("Director");

But when i run the form and change the value of textbox

Try this:

       combo1.Items.Clear();
       if (text1.Text=="A")
           {
            combo1.Items.Add("MD");
            combo1.Items.Add("Director");                
            combo1.Items.Add("President");
            combo1.Items.Add("Chairman");
            combo1.Items.Add("FullTimeDir");
            combo1.SelectedIndex = 0;
           }
       else if (text1.Text == "B")
           {
           combo1.Items.Add("Director");
           combo1.SelectedIndex = 0;
