[Foudhil yasser]

Hello all,
I want to make ComboBox Readonly, i don't find a good Solution in the forum.
I don't to use Skin...
So
I implemented a simple code !!! that i maked with help on demo:

            if (ZoneText is RadComboBox)
            {
                ((RadComboBox)ZoneText).EnableViewState = false;
                if (mode == ModeEdit.ADD)
                {
                    ((RadComboBox)ZoneText).BackColor = Color.White;
                    ((RadComboBox)ZoneText).ShowToggleImage = true;
                    //((RadComboBox)ZoneText).ShowDropDownOnTextboxClick = true;
                    //((RadComboBox)ZoneText).ChangeTextOnKeyBoardNavigation = true;
                    ((RadComboBox)ZoneText).OnClientKeyPressing = "";
                    ((RadComboBox)ZoneText).OnClientDropDownOpening = "";
                    ((RadComboBox)ZoneText).EnableTextSelection = true;

                }
                if (mode == ModeEdit.BROWSE)
                {
                    ((RadComboBox)ZoneText).BackColor = Color.FromName("#E6E6E6");
                    ((RadComboBox)ZoneText).ShowToggleImage = false;
                    //((RadComboBox)ZoneText).ShowDropDownOnTextboxClick = false;
                    //((RadComboBox)ZoneText).ChangeTextOnKeyBoardNavigation = false;
                    ((RadComboBox)ZoneText).OnClientKeyPressing = "CancelKeyPress";
                    ((RadComboBox)ZoneText).OnClientDropDownOpening = "CancelDropDown";
                    ((RadComboBox)ZoneText).EnableTextSelection = false;

                }
                if (mode == ModeEdit.EDIT)
                {
                    ((RadComboBox)ZoneText).BackColor = Color.White;
                    ((RadComboBox)ZoneText).ShowToggleImage = true;
                    //((RadComboBox)ZoneText).ShowDropDownOnTextboxClick = true;
                    //((RadComboBox)ZoneText).ChangeTextOnKeyBoardNavigation = true;
                    ((RadComboBox)ZoneText).OnClientKeyPressing = "";
                    ((RadComboBox)ZoneText).OnClientDropDownOpening = "";
                    ((RadComboBox)ZoneText).EnableTextSelection = true;

                }
            }

    public enum ModeEdit
    {
        ADD,
        EDIT,
        BROWSE
    }

and finnaly
i make 2 simple function JS !!!

<script type="text/javascript">

    function CancelDropDown(sender, eventArgs) {
         eventArgs.set_cancel(true);
    }

    function CancelKeyPress(sender, eventArgs)
    {
        eventArgs.get_domEvent().keyCode = null;
    }


</script>

Code not complexe, but make combo like textBox,
enjoy!!!!

Came to this thread looking for an elegant solution to the telerik controls: DropDown, CheckBox, DateTimePick, etc. Want to have a readonly functionality implemented in them. Marking them Enabled = False is the most ugly solution. The above mentioned solution is for ASP.net. I required WinForms.

Hi Hassan,

Could you please post your question in the WinForms forums here?

Kind regards,

I thought this was the WinForms. I have posted to the correct sub-heading: Read-Only for all Editors

this works quite okay, but to hide the borders do in addition following:

in .cs:
((RadComboBox)ZoneText).CssClass = "RadComboBox_Default_disabled";

in .aspx:
...
    <style type="text/css">
    div.RadComboBox_Default_disabled .rcbInputCellLeft,
    div.RadComboBox_Default_disabled .rcbInputCellRight,
    div.RadComboBox_Default_disabled .rcbArrowCellLeft,
    div.RadComboBox_Default_disabled .rcbArrowCellRight
    {
        background-image: none;
        padding-left: 0px;
    }
...


    </style>
