RadDropDownList ReadOnly not working with SelectNextOnDoubleClick

[Francois]

If SelectNextOnDoubleClick is enabled, even if the control is set to ReadOnly = true, you can change the value by double clicking on the control.

The only workaround seems to disable the setting...

Also :

You can select a value using the keyboard when DropDownStyle = DropDownList by typing the first letter of the item.

You can select a value using the mouse wheel when DropDownStyle = DropDown by scrolling the mouse wheel in the item.


Did you put an intern on that functionnality? lol

Sorry to spam the thread, but here's what I'll be using until the behavior is fixed : 

public static void SetReadOnly(this RadDropDownList ddl, bool readOnly)
{
    ddl.ReadOnly = readOnly;

    // If not disabled, user can change the value
    ddl.SelectNextOnDoubleClick = !readOnly;

    if (ddl.DropDownStyle == RadDropDownStyle.DropDown)
    {
        // User can change the value by scrolling on the control
        ddl.EnableMouseWheel = !readOnly;
    }
    else if (ddl.DropDownStyle == RadDropDownStyle.DropDownList)
    {
        // User can select an item by typing the first caracter of an item
        ddl.DropDownListElement.ListElement.KeyboardSearchEnabled = !readOnly;
    }

    // Indicate to the user the state of the control
    if (readOnly)
    {
    /
        ddl.DropDownListElement.ArrowButton.Fill.BackColor2 = Color.FromArgb(175, 175, 175);
        ddl.DropDownListElement.ArrowButton.Fill.BackColor = Color.FromArgb(210, 210, 210);
    }
    else
    {
        ddl.DropDownListElement.ArrowButton.Fill.ResetValue(FillPrimitive.BackColorProperty, ValueResetFlags.Local);
        ddl.DropDownListElement.ArrowButton.Fill.ResetValue(FillPrimitive.BackColor2Property, ValueResetFlags.Local);
    }
}

Hi Francois,

Thank you for reporting these cases.

We tried to make sure this functionality on a way that our users are still able to change the SelectedIndex via code, hence these cases were omitted. I have logged this and we will resolve it for the next release. Here is a link to the item: http://feedback.telerik.com/Project/154/Feedback/Details/122934. 

You Telerik Points have been updated for this report.

You already have a work around that you can work with.

Regards,
Stefan
