radGrid Popup Form Template Validation Issues

I'm running into a number of issues trying to do validation of controls in a popup form template of a radGrid:

1) None of my client-side validation funtions are firing
2) I cannot get the NEW value of the radEditor in my server-side custom validation function
3) When the insert form is redisplayed with errors, the content of the radEditor displays the original value, not the new value (changes are lost)

I'm using IE 9.0, and radControls Q3 2012.

This is the code for two of my editor controls that are having an issue (and the update button):

<telerik:RadTextBox ID="rtbTItle" runat="server" Width="400" TextMode="SingleLine" Text='<%# DataBinder.Eval(Container, "DataItem.Title") %>' Skin="WebBlue">

</telerik:RadTextBox>

<asp:RequiredFieldValidator ID="rfvTitle" runat="server" ControlToValidate="rtbTitle"

ErrorMessage="You must enter a Title" ValidationGroup="vgEditor" ForeColor="Red" Font-Bold="true">*</asp:RequiredFieldValidator>

<asp:CustomValidator ID="cvTitle" runat="server" ControlToValidate="rtbTitle"

ClientValidationFunction="cvTitle_Validator" OnServerValidate="cvTitle_ServerValidate" EnableClientScript="true"

ErrorMessage="Title cannot contain 'x'" ValidationGroup="vgEditor" ForeColor="Red" Font-Bold="true">x</asp:CustomValidator>

<telerik:RadEditor ID="reItemText" runat="server" BorderStyle="None"

OnClientLoad="reItemText_OnClientLoad" OnClientModeChange="reItemText_OnClientModeChange"

Width="800" Height="300" AutoResizeHeight="false" EnableResize="false" ToolsWidth="800"

ContentAreaMode="Div" Skin="WebBlue" Content='<%# DataBinder.Eval(Container, "DataItem.ItemText") %>'>

</telerik:RadEditor>

<asp:CustomValidator ID="cvItemText" runat="server" ControlToValidate="reItemText"

ClientValidationFunction="cvItemText_Validator" OnServerValidate="cvItemText_ServerValidate" EnableClientScript="true"

ErrorMessage="Item Text is required" ValidateEmptyText="true" ValidationGroup="vgEditor" ForeColor="Red" Font-Bold="true">*</asp:CustomValidator>

<asp:Button ID="btnUpdate" runat="server" ValidationGroup="vgEditor" CausesValidation="true"

Text='<%# IIf(TypeOf Container is GridEditFormInsertItem, "Insert", "Update") %>' CommandName='<%# IIf(TypeOf Container is GridEditFormInsertItem, "PerformInsert", "Update") %>' />

These are my client-side validation functions (neither of which gets fired):

function cvItemText_Validator( sender, args ) {

console.log( "cvItemText_Validator" );

}

function cvTitle_ServerValidate( sender, args ) {

console.log( "cvTitle_ServerValidate" );

}

And these are my server-side validation functions:

Protected Sub cvItemText_ServerValidate(source As Object, args As System.Web.UI.WebControls.ServerValidateEventArgs)

System.Diagnostics.Debug.WriteLine("Admin_ManageNews:cvItemText_ServerValidate")

System.Diagnostics.Debug.WriteLine(String.Format(" ItemText: {0}", args.Value))

Dim oItem As GridEditableItem = DirectCast(DirectCast(source, CustomValidator).NamingContainer, GridEditableItem)

Dim oEditor As RadEditor = DirectCast(oItem.FindControl("reItemText"), RadEditor)

System.Diagnostics.Debug.WriteLine(String.Format(" ItemText: {0}", oEditor.Content))

End Sub

Protected Sub cvTitle_ServerValidate(source As Object, args As System.Web.UI.WebControls.ServerValidateEventArgs)

System.Diagnostics.Debug.WriteLine("Admin_ManageNews:cvTitle_ServerValidate")

System.Diagnostics.Debug.WriteLine(String.Format(" Title: {0}", args.Value))

Dim oItem As GridEditableItem = DirectCast(DirectCast(source, CustomValidator).NamingContainer, GridEditableItem)

Dim oRTB As RadTextBox = DirectCast(oItem.FindControl("rtbTitle"), RadTextBox)

System.Diagnostics.Debug.WriteLine(String.Format(" Title: {0}", oRTB.Text))

End Sub

Both of the debug statements for the cvTitle validator display the correct value for the Title field, but neither debug statement for the cvItemText validator displays the new values, they display the old value.

Wow, it's all so freaking HUGE!

I'm sure there is a discussion on this somewhere, but why is it after the Q3 2012 release the font sizing was changed to a size only my grandmother could love? I mean since when is a 16 pt font considered the baseline normal? Now I find myself having to scale my browser to 75% just to get some semblence of usability when viewing the demo site.

Toolbox Will Not Drop Controls

As with many other people, I upgraded to your new release this weekend. I have managed to get through most of the issues by reading the forums. However, I have one issue that I haven't seen yet.

I created a new RAD c# website (.aspx) in VS2012. When I have the display file open and try to drag and drop controls on to the page, any Microsoft control that I grab, drag, and drop on to the page work fine. I tried many. No problems.

When I grab any Telerik control (makes no difference which one or from which group), I drop the control on to the page and nothing happens. No control is created.

If I manually create controls (such as copying ones from your demo site and pasting them into the page) the controls work just fine. It's just that no Telerik controls from the Toolbox are created.

Any workarounds available?
