    Hello all,
    In my project, i got 3 comboboxes. When the user clicks the first combobox and chooses an item, then the second combobox is loaded with  some data. The same mechanism works just fine when the user chooses items for the first time. When the user has already choosen the items on the 3 comboboxes, and tries to change the value in one of the comboboxes, then the following code is being used:

    foreach (RadComboBoxItem item in Middle_Tier.SideFormFunc.ConvertToComboBoxItem Middle_Tier.SideFormFunc.LoadArrondisements(Convert.ToString(cmbMunicipality.SelectedValue))))

    By the time that the program reaches cmbArrondisement.Items.Clear(); command, then it freezes and after 1 or 2 minutes it unfreezes. cmbArrondisement has only 1 item.

    Could you explain this problem?

    Thanks in advance

    Thank you for your response. It seems that i done something wrong. I wanted to make this thread on the WinForms/ComboBox Section of your forum. Im transfering my above request to the right section.
