Hello experts,

I have a template field in gridview, I'm formating the data to Phone#, if the data is null or empty my template field fails.
<asp:TemplateField>
<HeaderTemplate>
 Phone Number</HeaderTemplate>
<HeaderStyle HorizontalAlign="Center" Width="75px" />
 <ItemTemplate>
<asp:Label ID="lblPHNumber" runat="server" Text='<%# String.Format("{0:000-0000}",Convert.ToInt64(DataBinder.Eval(Container.DataItem, "PHN_NUMBER")))%>' /></ItemTemplate>
</asp:TemplateField>

Open in new window

How  can I fix this.

Thanks,
ASPDEV

Can you create a function that evaluates if PHN_NUMBER is null or empty and return nothing if true, and return the formatted string if false?

then just bind myFunction("PHN_NUMBER")

Try this,
<asp:Label ID="lblPHNumber" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "PHN_NUMBER") !="" ? String.Format("{0:000-0000}",Convert.ToInt64(DataBinder.Eval(Container.DataItem, "PHN_NUMBER"))) : ""%>' />
