After having created your pages using Iron Speed, users can enter anything into a free text field, which may be something completely intentional.

For example, there could be a field on the page titled "Description", presumably additional information relating to a particular record. You may wish that this description field should only ever allow numbers to be entered into the textbox.

It is worth noting that Iron Speed adds validation on the controls it builds, so dates cannot be entered incorrectly, decimal fields are only ever decimal figures etc.

 

Iron Speed bundles the AjaxControlToolkit.dll into every project, so that you can take advantage of a number of features that this .dll offers.

 

Going back to only allowing numbers to be entered, the following ASP snippet does not allow characters other than numbers to be entered, and should be placed in the cell for which this will be used for:

 

 <asp:FilteredTextBoxExtender ID="ftbe1" runat="server" TargetControlID="Description" FilterType="Numbers" />

 

Where TargetControlID equals the field that you want to add this functionality to.
