it still shows previous value in combobox text.

How would you expect us to know what you have done wrong when you do not show us the code that demonstrates this problem?

Use Selection Changed event. Show your code to help you better

Madhuri Gamane 20-Sep-14 0:16am

private void cmbdesignation_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
ClearAll();
if (cmbdesignation.SelectedItem != null)
{
Designation = cmbdesignation.Text; // it gives previous value (suppose i select teacher and prev was student, it still showing "Student")
Designation = cmbdesignation.SelectedItem.ToString(); // it gives "System.Windows.Controls.ComboBoxItem: Teacher"

}
}
