Validating textbox in gridview

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.

Meanwhile, we can use the Validate Row event in the same way to prevent the user from exiting the current row.

There are few myths about Sql Data Source and there are talks about its limitations. You can easily bind it with a database table and later bind it to a Grid View control.

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.

You are going to have to get the Client ID of the Text Box in your VB or C# code.

Once you have that, you're going to have to set the button's onclick attribute to the Java Script method (which is rather messy, with duplicate code, as acoder has pointed out).

Net You can apply a similar principle to a Drop Down List control that you have added in your Grid View control. Finally, I’ll check the value that the user has picked from the list. Add multiple controls to the Grid View control and check the script.

Yes, you can attach a Drop Down List to the Sql Data Source control. Remember, client validations are not fool proof and you cannot rely on these scripts only.
