GridView for ASP.NET Web Forms is fully compatible with Input for ASP.NET Web Forms controls. Using the Input for ASP.NET Web Forms controls, you can easily add in data validation to your grid, including masked, date, numeric, percent, and currency editing.

In the following steps you'll create template columns in the C1GridView control and add the C1InputNumeric and C1InputCurrency controls to those columns. Note that in the follow steps it is assumed that you have created a C1GridView control and bound it to the Products table of the NorthWind database.

Complete the following steps:

1. Right-click C1GridView and select Show Smart Tag from the context menu. From the C1GridView Tasks menu, select Property builder. The C1GridView Properties dialog box appears.

3. If the Create columns automatically at run time check box is selected, deselect it.
4. In the Selected columns list, remove the following columns by selecting the column and clicking the Delete button: ProductID, SupplierID, CategoryID, UnitPrice, UnitsInStock, UnitsOnOrder, and ReorderLevel.
   Note that you'll add template columns to replace most of these columns.
5. In the Available columns list, select Template Field from the list of column types.
6. Click the arrow button between the column lists to copy the Template Field to the list of Selected columns. Repeat this step two more times, so that you've added a total of three template columns.
