[CLOSED] ASP.NET Form Validation Request error when closing a Window containing a TextArea

[aengels]

When I run this code (press the button) I get a validationrequest error. How can get rid of this error without switching of this ASP.NET security feature.? It works fine when I use a Label instead of a TextArea.

        protected void ErrorButton_Click(object sender, DirectEventArgs e)
        {
            this.IncidentErrorWindow.Close();
            this.IncidentTabPanel.Enable();
        }

<ext:Window runat="server" ID="IncidentErrorWindow" Title="Error Message"  Hidden="true" Width="330"  Icon="cancel" Closable="false">
                    <Items>
                        <ext:FormPanel runat="server" Border="False" Padding="5" DefaultAnchor="100%" BodyStyle="background-color: #E0E0E0;"  ButtonAlign="Center">
                            <Items>
                                <ext:TextArea runat="server" ID="IncidentErrorMessage" MinHeight="120" ReadOnly="true" Margin="5" AutoScroll="true" />
                            </Items>
                            <Buttons>
                                <ext:Button runat="server" ID="IncidentErrorButton" Text="OK" >
                                    <DirectEvents>
                                        <Click OnEvent="ErrorButton_Click" />
                                    </DirectEvents>
                                </ext:Button>
                            </Buttons>
                        </ext:FormPanel>
                    </Items>
                </ext:Window>

The TextArea is being submitted during the DirectEvent request, which triggers the RequestValidation.

The following link provides information on how to disable RequestValidation:

Is there any way we can HTML-encode Direct Events somehow to comply with the .NET security? Also I think this is a better link as it explains how to disable Request Validation in .NET 4 or later :-)

Thank you,

Well, you could get the TextArea value, then encode it and set it back, in the .Before handler of the Button.
