RadMaskedTextBox for null value

[Tommy]

Hi team:
           Now I have a grid which band a database tabe, in the grid have a "phone" column  as the follow code
<telerik:GridTemplateColumn UniqueName="PhoneNumber" DataField="PhoneNumber"
                                        HeaderText="PPHONE" Visible="true" AllowFiltering="true" ReadOnly="true">
                                        <HeaderStyle HorizontalAlign="Center" Font-Bold="True" />
                                        <ItemTemplate>
                                            <telerik:RadMaskedTextBox ID="tboxPhoneNumber" runat="server"  Mask="(###) ###-#### x####"
                                                NumericRangeAlign="Left" Text='<%#Bind("PhoneNumber") %>' ReadOnly="true" >
                                            </telerik:RadMaskedTextBox>
                                        </ItemTemplate>
                                    </telerik:GridTemplateColumn>
but when the "PhoneNumber" field value is null, grid column  will show text "(___) ___-____x____",can you give me a hand I just want to show a empty string in the grid.
Thanks.

Hello Tommy,

I tried following code snippet for achieving the scenario. Try the following code snippet in RadGrid_ItemDataBound event for removing the Mask for RadMaskedTextBoxes which have null value.

CS:

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        RadMaskedTextBox text = (RadMaskedTextBox)item.FindControl("tboxPhoneNumber");
        if (text.Text == String.Empty)
        {
            text.Mask = "";
        }
    }
}

Thanks,
Princy.

Princy, I have met the same problem. Your reply did help me a lot also. But what if the phone number is without extension number just like "[phone] x____", how to remove the underline? I don't want to catch any underline in the grid whatever the phone numer is, not only for empty phone number.
Thanks.

Hi Princy:
    As joe said I also have the same problem about the phone ext num,now I think use the follow code can dealwith this problem,
but any good idea,can you give me.

protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)   {       if (e.Item is GridDataItem)       {           GridDataItem item = (GridDataItem)e.Item;           RadMaskedTextBox text = (RadMaskedTextBox)item.FindControl("tboxPhoneNumber");           if (text.Text == String.Empty)           {               text.Mask = "";                           }          if (text.Text.Length <3+3+4)           {               text.Mask = "(###) ###-####";                           }  else         {               text.Mask = "(###) ###-####x####";                           }      }   }
