Catering for DBNull.Value items.

[Ian Coetzer]

Hi

How can I set values (bind) to the RadNumericInput control:
(as shown below)

Value='<%# DataBinder.Eval(Container, "DataItem.Salary")%>'

But cater for DbNull.Value values?
The users do not want to see the value zero "0.0000" they want to be able to see that the value is null, nothing / blank textbox.
I receive a "Specified cast is not valid." error message if I try and bind it to a datatable with some Null values.

Here is my full RadNumericTextBox control declaration:

                        <telerik:RadNumericTextBox ID="radNumericTextBox" runat="server" Type="Number"
                            Value='<%# DataBinder.Eval(Container, "DataItem.Salary")%>'
                            LabelCssClass="radLabelCss_Web20" Skin="Telerik" Width="80px" style="TEXT-ALIGN: left"
                            Font-Size="8pt" >
                            <NumberFormat DecimalDigits="4" />
                            <FocusedStyle BorderColor="Red" BorderStyle="Double" />
                            <HoveredStyle BorderColor="Red" BorderStyle="Double" />
                        </telerik:RadNumericTextBox>
