Hi
I have Radgrid with few GridDateTimeColumn and it is bound to Datetime column from database, and i have null values in datetime column in my database, problem is i have griddatetimecolumn binded to datetime column but it show error if value from database is null

example.
<telerik:GridDateTimeColumn DataField="ApplicationDate" DataType="System.DateTime"    
HeaderText="ApplicationDate" SortExpression="ApplicationDate"   
SelectedDate='<%# Bind( "ApplicationDate" ) %>' UniqueName="ApplicationDate" /> 

now '<%# Bind( "ApplicationDate" ) %>' also contains null value if there is any date in database then there is no problem but if there is null value then it shows error : Sys.WebForms.PageRequestManagerServerErrorException: 


Please help me to resolve this i want to have GridDateTimeColumn in radgrid but with it also accepts null date value.

Hi Siingh,

Try removing: SelectedDate='<%# Bind( "ApplicationDate" ) %>' from the mark-up for the column.

Than how do i bind control?

I need to bind control so i can use inbult editting and adding new rows to datagrid.

if i remove that tag then adding new row will not save any value into ApplicationDate column

Hi Siingh,

Setting the DataField property of the column is enough to take care of the binding. You should set a Binding expression only if you are using a template column and defining manually the date-time controls. In that case, a binding expression is valid and obligatory, but not when using a GridDataTimeColumn type.

All the best,
