A suggestion :- Please avoid using short text like u instead of using You.

Solution 3

Handle the SelectedIndexChanged[^] event for the first ComboBox, then update the second combo box based on the SelectedItem[^] value for the first ComboBox.

Update a combo box automatically when first combo box gets some value[^]

Actually i forgot to inform in my question that i am using VS2008. Another thing is there is no function like DataBind(). so What to do.
Thanking You in advance.

Solution 2

C#

protected void cmb1_OnSelectedIndexChanged(object sender,EventArgs e)
{
    long value = Convert.Int64(cmb1.SelectedValue);
    FillCombo2(value);
}
void FillCombo2(long Combo1Value)
{
   cmb2.Items.Clear();
// fill dataset based on combo1Valuee and assign it to cmb2
    cmb2.dataSource = dt1;
    cmb2.DisplayMember ="Name";
    cmb2.ValueMember ="Id";
    cmb2.DataBind();
}

This answer would be much more valuable if you showed how the passed in long, the value of 'Combo1Value in 'FillCombo2, was used to construct the dataset that I assume the name 'dt1 refers to.
