How to Prevent users from pasting data into RadComboBox?

[Prasad]

Hi All,

Markup of my radcombobox looks like the following. Even with the following configuration, users are able to paste invalid data into RadComboBox. Can someone please let me know a way to prevent that?

Regards,
Prasad

<telerik:RadComboBox ID="rcbDepartment" runat="server"  Width="200px"
           EmptyMessage="Any Department"  DataTextField="text" DataValueField="value"
           AutoCompleteSeparator=";"  AllowCustomText="false"
           MarkFirstMatch="true"  > </telerik:RadComboBox>

Hello Prasad,

Here is what you can try to overcome this behavior:

function clientLoad(sender, args) {
    var input = sender.get_inputDomElement();
    input.addEventListener("paste", pasteHanlder);
}

function pasteHanlder(e) {
    return false;
}

<telerik:RadComboBox ID="rcbDepartment" runat="server" Width="200px" EmptyMessage="Any Department"
    DataTextField="text" DataValueField="value" AutoCompleteSeparator=";" AllowCustomText="false"
    MarkFirstMatch="true" OnClientLoad="clientLoad">
    <Items>
        <telerik:RadComboBoxItem Text="item1" />
        <telerik:RadComboBoxItem Text="item2" />
    </Items>
</telerik:RadComboBox>

I hope this helps.

All the best,
