Hi,
I have used the DataTextFormatString="{0:(###) ###-####}" to format the phone number in the GridButtonColumn which is not working. Please find the solution to format the phone in the GridButtonColumn in the Grid.
Note: Im using the Classic RadGrid.
The DataTextFormatString property for phone number will only works if your
data type in that column is of
type numeric. I think you have stored the phone number as 'string'. So in ItemDataBound event, you
can convert the data type of that
column to something that can be formatted using the format string. Sample code is given below for your reference.
