Scenario You have a Grid View that displays data of an employee and has a Text Box that accepts an employee address. If you simply add a button and a required field validator to validate against the address Text Box, a single button will validate against all the rows.The logic used to perform the validation will assign a unique validation group for each row.

The sub-sections contain the complete steps for getting data into the grid, supporting editing the data, and validating the contents of the grid cells.

If you are brand new to the ASPx Grid View then read all of the sections.

To validate data to grid cells and rows, we need to use the Validate Cell event, which will be raised by the Kettic Data Grid View when there are any changes to the current cell or when the grid cell loses input focus like.

Before we validate data to grid cell, we need to cancel the Validate Cell event to prevent the users from exiting the cell until entering a valid editor value or cancelling the edit process.

Now to decide where to set this group validation is the event where the binding of the grid happens.

The binding of the grid happens on the Row Data Bound Event, that is why we assign a validation group to the controls present in each row inside in the Row Data Bound event.

shoud I create a table in my dataset for such a task? thanks, rodchar rodchar, In addition to Bernie's suggestion. If the table is not too large, I would create a Data Table out of it, define a primary key, then use the Contains method. Primary Key = New Data Column() ' check to see if the row is in the table. Contains is overloaded to accept a single value as above or an array of values...

By default, if the value of a cell does not pass the validation process, the cell will exit edit mode and the value of the cell will be returned to its original valid value.

The next step is to turn on the edit metaphors in the ASPx Grid View.

NET controls and their many members for interesting aspects and interesting ways to present them.
