Here is the basic code: <telerik:RadTextBox ID="RadTextBox1" runat="server" TextMode="MultiLine" Enabled="False"> </telerik:RadTextBox>
The RadTextBox (and other input controls as appropriate) should have an aspx property to automatically trim leading & trailing whitespace from user input. This will help ensure that good quality data is passed to the database. The only way this can currently be done is to custom code "mytextbox.Text.Trim();" for every control on the page, before the property is sent to the database.
Fixed: RadMaskedTextBox value not submitted correctly when DisplayMask differs from Mask in some cases.
