Here is the markup, I have been trying to cancel the valueChanging, the TextChanging - just about all of the Change events for a WHDG Editor Provider (TextEditorProvider) , however, when I simply set the client function to the following,

// This is not canceling the event

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

I have my WHDG as follows (in assigning the Editor, and the Behavior setting for the column

(Behaviors in my Child Band)

<Behaviors

>

<ig:EditingCore AutoCRUD="false" Enabled="true" EnableInheritance

="true">

<Behaviors

>

<ig:CellEditing EditModeActions-EnableOnActive="true"

EditModeActions-MouseClick="Single"

EditModeActions-EnableOnKeyPress

="true">

<ColumnSettings

<ig:EditingColumnSetting ColumnKey="ChildID" EditorID="TestTextEditor"/>

</ColumnSettings>

<EditModeActions EnableOnActive="True" EnableOnKeyPress="True" MouseClick="Single"

/>

</ig:CellEditing>

<ig:RowAdding Enabled="true" Alignment="Bottom" EnableInheritance="true"

<ColumnSettings >

</ColumnSettings

</ig:RowAdding>

</Behaviors>

(Text Editor Provider)

<ig:TextEditorProvider ID="TESTTEXT">

<EditorControl ID="TestTextEditor" runat="server" StyleSetName="Default">

<ClientEvents ValueChanging="Default_Changed" />

</EditorControl>

</ig:TextEditorProvider>

(I am beginning to lose faith after a conversion of 300 hours from the UltraWebGrid - you can't Do an UpdateCellBatch - whats up with dat ?)

I am storing my data(as it is updated and added to in Cache, and then update all the changed data during a save, as you can not manually add rows or update rows on the client without having a postback occur.  But I digress - anyone else seen or had this problem, or am I just doing this wrong ?

Very Urgent, Thanks!
