RadmaskedTextbox in radgrid template generates error formatted as phone number

[Bill Deihl]

I have a table with a phone number stored as a long/nullable. (I can’t change it…)

All is well except for editing the record with an empty fax number in this case. An error dialog tells me that I don’t have a valid value for int64.

If I input a value of 0 in the radmaskedtextbox the record saves but then I have a 0 for the fax number. I need it to be blank/null if there is no number entered

Thanks for any help!

<telerik:GridBoundColumn DataField="AgencyMainFax" DataType="System.Int64" HeaderText="Main Fax" DataFormatString="{0:(###) ###-####}"  AllowFiltering="false" SortExpression="AgencyMainFax" UniqueName="AgencyMainFax">

</telerik:GridBoundColumn>

The edittemplate:

<telerik:radmaskedtextbox ID="RadMaskedTextBox2" runat="server" Mask="(###) ###-####"

Text='<%# Bind("AgencyMainFax") %>' Width="125px">

</telerik:radmaskedtextbox>

Hello Bill Deihl,

Instead of using "Text" property for binding the value you could try using the "Value" property or the other tree analogs of text properties which should not returns 0 but just null.
Please test this approaches and let us know if this helps.
