Use the Databinding event to change the value

Show me your code I think you must retrieve the information with sqldatareader and then use the property isdbnull of the datareader.

<ew:CalendarPopup id="CalendarPopup5"
   SelectedDate='<%# DataBinder.Eval(dsWarranty1, "Tables[tb_sav_warranty].DefaultView.[0].wty_estimate_validate_date") %>'>

and after on the onLoad event :

daWarranty.SelectCommand.Parameters["@hdr_index"].Value = (string)Session["hdr_index"];
daWarranty.Fill(dsWarranty1);      

CalendarPopup5.DataBind();

that's it !

but when there is a null value , it raise an convertion error.. I think this control don't accept null value so if I can transform to 1.1.1900 it's great for me ...

thanks

First DOnt use dataset.
Second if you use the embedded databinder.eval you dont have a way to control for null values. You must make a method to retrieve it programatically. It seems that you are using the dataset designer.

there is not a way to intercept the value like the ItemDataBound property of the datagrid and change it ??

Is this from a stored proc?

If so, why not just return 1/1/1900 in the query?


Select IsNull(SomeDateField, "1/1/1900") From tablename

No with the calendar.

And why are u using typed datasets? its one of the worst practices for real developers. You should make it all by hand

so okay djhex, what do I have to use, DataView ?
I just use dataSet because I can use it in the IDE to DataBind my controls...

i'll try monday now it's week.end ;-)

ok.

I'd say points to djhex.
