Hello
My scenarion is this
1- i have a Form which is dynamically generated with some XML configuration information.
2- i am attaching Data Binding for a textbox in Text_Loaded event a well as Validation Rules and i am attaching Validation.AddErrorHandler for showing message boxs
3- Data Source for the binding is a DataTable.
4- I am having record navigation buttons on the form generated in step 1 (Next,Last,First,Previous)
5- If user edits data with invalid values in record no 1 validation fires and it creats a red border
6-user press Next button to navigate to record no 2 but does not update error field in record no 1 i.e. she leaves record no 1 with some error not in my data source but on the form.
7- She came back to record no 1 , here my problem begins , Record no 1 is updated with old values and does not show error which she made.
i know that ValidationRules will not allow wrong input to update my data source which is fine but i need to handle point no 7 , there is no direct way to handle this situation , any help is much appriciated
