[Solved] 2010 Q1 SP2 DataFormatString

[Naresh]

Hello,

We just upgraded to SP2 and still can not seem to get the DisplayFormat data attribute to work in RadGridView.

Here is the column definition (the grid is read-only):

<telerik:GridViewDataColumn DataMemberBinding="{Binding PreferredPhone}"/>

Here is the property it is bound to:

        [Display(ShortName = "Preferred Phone", AutoGenerateFilter = false)]

        [DisplayFormat(DataFormatString = "{0:###-###-####}")]

        public string PreferredPhone

The ShortName and AutoGenerateFilter values are being applied while the DataFormatString is not. I have verified that the Upgrade Wizard worked and that the project is now referencing the 2010.2.924.1040 version of the DLL's.

Any ideas why this does not work?

Thank you,
Brian

To correct myself, it's 2010 Q2 SP2.

Hello Brian,

The format string you've provided is applicable only for number types. For example if you change type of the property PreferredPhone to long instead of string everything should work as expected.
You can easily test what cell would display via:

code: string.Format("{0:###-####-####}", "55512341234")
result: "55512341234"
code: string.Format("{0:###-####-####}", 55512341234)
result: "555-1234-1234"

I hope this makes sense.

Best wishes,

It was definitely my fault. DataAnnotation formating works great now.

Thanks!
