WebDropDown Always show Checkboxes
posted

I added a WebDropDown to a Content page and set it to allow multi selection and with MultiSelectionType Keyboard. It worked properly. Then, I changed the MultiSelectionType to Checkbox and it worked properly. Then, I changed the MultiSelectionType back to keyboard and the check boxes still show. I have removed the dropdown box from the form and placed a new one and the checkboxes still show. I have reset IIS and cleared the cache on the server and the checkboxes still show.

How can I make the checkboxes in the WebDropDown control go away?

Thanks,

Fernando

    You can try to customize the DropDown control, then make the Checkboxes disappear. Here are some codes for example:

    private void dropDownList_VisualListItemFormatting(object sender, VisualItemFormattingEventArgs args)
    {
        if (args.VisualItem.Chosen)
        {
            args.VisualItem.NumberOfColors = 1;
            args.VisualItem.BackColor = Color.Green;
            args.VisualItem.BorderColor = Color.Purple;
        }
        else
        {
            args.VisualItem.ResetValue(LightVisualElement.NumberOfColorsProperty, Kettic.WinControls.ValueResetFlags.Local);
    args.VisualItem.ResetValue(LightVisualElement.BackColorProperty, Kettic.WinControls.ValueResetFlags.Local);
    args.VisualItem.ResetValue(LightVisualElement.BorderColorProperty, Kettic.WinControls.ValueResetFlags.Local);
        }
    }
