Radgrid date format

[Tal]

Hi dear support,

I have a radgrid to which I query from my db with date conversion.
SelectCommand="SELECT [eventID], [eventName], CONVERT(VARCHAR(10),[date],103) as date, CONVERT(VARCHAR(5),[hour],108) as hour FROM [tblevents]"

When I make an event of "search_button"  I can reload the new datasource to the radgrid but I can't change the date format back.
I tried to use the "DataFormatString" property with the value {0:DD/MM/YYYY} but with not luck.

Will appreciate your help.

Thanks,
Tal

Hello Tal,

How are you changing the DataFormatString? Modifying the property should do: just get hold of the column before rebinding the grid and set its DataFormatString property to the desired new value. I could not see in your code where you are attempting this.

Hey,
thanks for the answer.
the property is in <telerik:RadGridID="RadGrid1" 
I just didn't copied it when posted the question.

How do I get a hold of the column before rebinding the grid ?

Thank you,

Tal

Hi Tal,

You have a GetColumnSafe method on the MaterTableView object. It accpets as paramter the unique name of the column.
