    I have a RadGrid bounded with an ObjectDataSource. I have a DateTime parameter that gives some problem.
    When I try to update data i get the following error: "Cannot convert value of parameter 'Data' from 'System.String' to 'System.DateTime' ".
    I tried also to specify the format of date:
     <telerik:GridBoundColumn DataField="Data" DataType="System.DateTime"  


    HeaderText="Data" SortExpression="Data" UniqueName="Data" EditFormHeaderTextFormat="{0:dd/MM/yyyy HH:mm:ss}" DataFormatString="{0:dd/MM/yyyy HH:mm:ss}">





    or to use:




    telerik:GridDateTimeColumn DataField="Data" DataType="System.DateTime" HeaderText="Data" SortExpression="Data" UniqueName="Data" DataFormatString="{0:dd/MM/yyyy HH:mm:ss}" >









    I get always the same error, what can I do to solve?

    I assume that there is an issue with the parameters set in your Insert/Update methods. The links below show how to use ObjectDataSource with RadGrid
