Up till now we used the validation controls to validate Grid View input on client and server side.Double click on the Custom Validator control to go into the Server Validate event handler and write the following code in it. However, at times you many need more control and flexibility than that is provided by validation controls.

Just like we attached the Required Field Validator control to the Text Box, attach a Custom Validator to the Contact Name column. If you run the web form and try entering wrong value in the Contact Name column then you will see the error message displayed as before and the value will not be accepted by the Grid View control.In our example we will illustrate the use of Updating event for the validation purpose.Add Grid View1_Row Updating event handler as shown below: The Row Updating event handler receives an event argument of type Grid View Update Event Args.Enter the database details as per your setup and click on OK.On the next step select Customer ID, Company Name, Contact Name and Country columns (Figure 2). NET 2.0 Grid View control allows us to quickly edit and delete records.

However, most of the real world cases call for validating the data being edited or deleted. Drag and drop an SQL Data Source control on the web form.

By default when the Grid View controls goes in edit mode, it displays Text Boxes for entering values.

You can not attach validation controls directly to these Text Boxes.

We check the value entered in the Text Box using args. Especially the following events are important for validation point of view.

Make Company Name blank and click on Update button.

The limitations of this coercive right are: that its exercise be necessary ; and that damage be not inflicted beyond measure -- first of necessity and secondly of proportion with the subject-matter of right at issue.
