Page.IsCallback not being set on ajax error

[Vance Smith]

Hello,

I have an Ajaxed RadGrid and while configuring my applications error handling logic I purposely set up the situation for an error to occur when a grid item is edited.

<EditItemTemplate>  

<telerik:RadMaskedTextBox

 

id="IN_RMTB"  

 

 

 

runat="server"  

 

Mask="##-#######"  

 

Skin="Office2007"  

 

Width="65px"  

 

EmptyMessage="00-0000000" />

 

##-####### (make sure you pad the number with zeros - ex: 08-0000123)

 

<asp:RequiredFieldValidator

 

 

 

id="IN_Suffix_RFV"

 

 

 

runat="server"

 

 

 

ErrorMessage=" Required"

 

 

 

ControlToValidate="IN_RMTB2"

 

 

 

Display="Dynamic" />

 

 

 

</EditItemTemplate>

 

 

 

 

 

Notice that the ControlToValidate property says "IN_RMTB2" when it should say "IN_RMTB".

Anyways, my problem is that when this error occurs (by clicking the edit link for the row) the Page.IsCallback property is not being set. This is thwarting some of my custom error handling plans. Do you have any suggestions or explanations why Page.IsCallback is not being set to true in this situation?

On an unrelated note: the post above had the sample code formatted just fine but when I posted it place all the extra line breaks. Also, when I edited the post and removed the line breaks it placed them back in.
