combo box on a windows form

sea

I'm trying to use a combo box on a windows form which will change its display on event of changing combo selection. This is the method I wrote:

private void SurveyChooserCombo_SelectedIndexChanged(object sender, EventArgs e)
		{
			DAL dal = new DAL();
			switch (SurveyChooserCombo.SelectedIndex)
			{
				case 0:
					SrNo = 1;
					break;
					
				case 1:
					SrNo = 2;
					break;

				case 2:
					SrNo = 3;
					break;
				default:
                   SrNo = 3;
					break;
			}

It doesn't do the job. Please help me find why. TIA, sea#

What is SrNo? What do you want to change in the combo box?

"doesn't do the job" is very vague, what doesn't work in particular?

SrNo, which is an int represents survey no. Each time I change the item in combo, it is changed. "doesn't do the job" means SurveyChooserCombo.SelectedIndex seems to be left unchanged. When I run the application the form doesn't change the display as expected. Also cannot run it in debug mode, as I get "there is no source code available for current location", when trying to run over method more then once- to make the change in index come true. sea#

Are you sure you have added event handler? i.e. comboBox.SelectedIndexChanged+=new SelectionChangeHandler(<>) ??? This is done automatically by Visual Designer - simply naming method SurveyChooserCombo_SelectedIndexChanged does not automatically associate it with the control... - Another possibility is that the event may not be fired if combo box list style is not a selection from drop-down list but a mixture of type-in and select from the list... Hope this helps. Regards JP

Nothing complicated. What else should I do to make it change once selction changed? TIA, sea#

Wrote this code:

private void SurveyChooserCombo_SelectedIndexChanged(object sender, EventArgs e)
{
if (SurveyChooserCombo.Text.Equals("Survey1"))
SrNo = 1;
else if (SurveyChooserCombo.Text.Equals("Survey2"))
SrNo = 2;
else if (SurveyChooserCombo.Text.Equals("Survey3"))
SrNo = 3;
else
SrNo = 3;
GetResults (SrNo);
}

stil event is not fired, dsiplay doesnot changed.
