ValueChanging event

How do you use the ValueChanging event from inside an EditorProvider

I have defined an EditProvider

                        <ig:TextEditorProvider ID="tepPercent">

                            <EditorControl HorizontalAlign="Right" ClientEvents-ValueChanging="validatePercent4Decimals"></EditorControl>

                        </ig:TextEditorProvider>

 

And a javascript handler

            function validatePercent4Decimals(sender, args) {

                var oldfieldvalue = args.get_oldValue();

                var newfieldvalue = args.get_value();

                if (isNaN(newfieldvalue)) {

                    args.set_value(oldfieldvalue);

                    args.set_cancel(true);

                }

            }

 

I've debugged it and can see it is running, and if I enter 34r, the inNan tests true and the set_value and set_cancel are called. But the value on the grid does not change from the 34r...

 

What's going on?

    Hello bixbarton ,

    Thank you for posting in our forums.

    I tried to reproduce the issue with the latest service release of v11.1 ( 11.1.20111.2064) but with no avail.

    I strongly recommend you installing it.

    The newly entered value is removed and the old value is restored

       <EditorProviders>

                    <ig:TextEditorProvider ID="whdg1_TextEditorProvider1">

                        <EditorControl runat="server">

                            <ClientEvents ValueChanging="whdg1_TextEditor_ValueChanging" />

                        </EditorControl>

                    </ig:TextEditorProvider>

                </EditorProviders>

    …. 

     

     <ig:BoundDataField DataFieldName="ItemParent" Key="ItemParent" Header-Text="ItemParent">

                        <Header Text="ItemParent"></Header>

                    </ig:BoundDataField>

     

    ….

     

      <ig:CellEditing>

                                <ColumnSettings>

                                    <ig:EditingColumnSetting ColumnKey="ItemParent" EditorID="whdg1_TextEditorProvider1" />

                                </ColumnSettings>

                            </ig:CellEditing>

    What is the type of the column that you are setting the editor provider to?

    Hope hearing from you.
