Undo doesn't work for Delete and Backspace

[Caesar]

Hi,

If there is an existing text in the editor, setting focus by clicking and then pressing delete or backspace to delete text, then the undo button isn't enabled.

Even after typing some other text, and then deleting with delete-key, the undo/redo-chain isn't working as expected.

This doesn't work in the demo either:

Hello Rikard,

The delete / backspace commands are not included into the Undo list to prevent editing performance problems when working with large content.

Nevertheless, the requested Undo/Redo functionality is already logged in our PITS system and you can vote for it here: http://www.telerik.com/support/pits.aspx#/public/aspnet-ajax/1672.

We will raise its priority if more users request this feature.

Hi,

I (and everybody I have asked in my office) thinks deletions are even more important to undo than typing...

Hi,

Is there any other solution for this? For example replacing some internal telerik javascript method?
No one that I have asked understands why there is an undo button that doesn't undo deletions...

Hello Caesar,

Please, try the following JavaScript function that will enable the DeleteKey command in the Undo / Redo list:

<telerik:RadEditor ID="RadEditor1" runat="server" OnClientLoad="OnClientLoad">
</telerik:RadEditor>
<script type="text/javascript">
function OnClientLoad(editor, args)
{
    editor.attachEventHandler("onkeydown", function (e) {
        if (e.keyCode == 8 || e.keyCode == 46) {
            var oCmd = new Telerik.Web.UI.Editor.GenericCommand("DeleteKey", editor.get_contentWindow(), editor);
            editor.executeCommand(oCmd);
        }
    });
}
</script>

Hi Dick,

Could you please provide detailed steps to reproduce the problem? Right now I am unable to reproduce the issue as shown in the following video: http://screencast.com/t/rFufKIvd.

Hi, I have tried this solution and is not working for me.

I have seen that in my case the OnClientLoad="OnClientLoad" is not doing anything, the function is not being triggered.

In my case I have the RadEditor inside of a Telerik:RadTabStrip as follows:

   <telerik:RadTabStrip ID="ResourceTabContainer" runat="server" SelectedIndex="0" MultiPageID="RadMultiPage">
                                <Tabs>
                                    <telerik:RadTab Text="Editor" PageViewID="EditorTab" Value="EditorTab">
                                    </telerik:RadTab>
                                </Tabs>
                            </telerik:RadTabStrip>
                            <telerik:RadMultiPage ID="RadMultiPage" runat="server" SelectedIndex="0">
                                <telerik:RadPageView ID="EditorRadPageView" runat="server">
                                    <telerik:RadEditor ID="ResourceValueEditor" runat="server" SkinID="BasicSetOfTools" OnClientLoad="OnClientLoad"
                                        Width="100%" Height="400px" StripFormattingOnPaste="MSWordRemoveAll">
                                        <SpellCheckSettings spellcheckprovider="EditDistanceProvider"></SpellCheckSettings>
                                    </telerik:RadEditor>
                                </telerik:RadPageView>
                            </telerik:RadMultiPage>

And my java script function is this:

function OnClientLoad(editor, args) {
   alert("OnClientLoad function called");
            editor.attachEventHandler("onkeydown", function (e) {
                if (e.keyCode == 8 || e.keyCode == 46) {
                    var oCmd = new Telerik.Web.UI.Editor.GenericCommand("DeleteKey", editor.get_contentWindow(), editor);
                    editor.executeCommand(oCmd);
                }
            });
        }

But I can't even see the "OnClientLoad function called"  message.

Could you please tell me what could be the problem?

Thanks in advance

Never mind

The problem was an overwrite for the OnClientLoad event from the code behind that I wasn't aware of.

Thanks
