Specified cast is not valid

[Shed Dweller]

I have a simple grid bound to an object data source.

I have configured the grid to use a form template for inline editing.

When I click the grid's "Add new record" button I get an exception....

Specified cast is not valid

I have traced this to the use of  RadDatePickers in the form.  If I use ordinary text fields for the dates then the problem doesn't occur.

This is the snippet of code that is in the <FormTemplate>

<

telerik:RadDatePicker ID="RadDue" runat="server" SelectedDate='<%# Bind("DueDate") %>' EnableTyping="false">

</telerik:RadDatePicker>

Hi Sean,

Please use DbSelectedDate instead.

Many thanks Vlad!  That worked perfectly.

Hi Sean,

You can also refer the following KB article which explains about RadDatePicker as the editor in GridTemplateColumn.

Thanks
