If you do not want the formatting as part of the value stored, you will need to remove the formatting programmatically.Hi, I need help with the Lin Q and Details View control.

Value _ Select New With 'Trying to read new name entered 'Return "" with this method dv. Item(1) 'Null Reference Exception with this method CType(dv. The formatting is then programmatically removed before the value is updated in the data source.Data-bound controls (such as Details View, Form View, and Grid View) have different display modes that allow the user to read, edit, or insert records.

Item Updating event, I get nothing from the Text Box. With the later method, I can only access read-only fields and headers. There is some great documentation on MSDN regarding this.In general, if you need code (custom event handlers/validation) behind your Info Path forms you should use the VSTO Info Path template and create a project alongside your workflow project.
