Adult dating sites that accept american express - Datagridview validating input

Here, our validation criteria is that the entered name must not contain title of courtesy (Mr./Mrs./Ms.). That is when you can handle certain events of Grid View control.

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

Inside the event handler we added two validation conditions: We used the New Values collection to check the entered country.

This will display the template designer for the column as shown in Figure 6.

Next, drag and drop a Required Field Validation control below the Text Box.

There can be several approaches taken for validating data. For our example we are going to use Customers table of Northwind database. Open its smart tag and choose "Configure Data Source" option to start Configure Data Source wizard.

On the first step of the wizard click on "New Connection" button to open a dialog as shown in Figure 1.

This way you can attach client side validation controls to the Grid View columns.

Let's proceed further by validating on the server side.

Right click on the Grid View and select "End template editing" Run the web form.

Click on the Edit button of the Grid View so that it goes into the edit mode.

We will use the Custom Validator control for this purpose.

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.

NET 2.0 Grid View control allows us to quickly edit and delete records.
