Hi Phani,

After inspecting your code I found that you are using the incorrect id to access the RadDateTimePicker. Please try the following code snippet.

C#:

RadDateTimePicker fromdt = RadWindow1.ContentContainer.FindControl("DtFromdate") as RadDateTimePicker;
RadDateTimePicker todt = RadWindow1.ContentContainer.FindControl("DtTodate") as RadDateTimePicker;

Hope this helps.

Thanks,
Princy.

HI ,
Princy
sorry for typing wrongly.
iam using
        RadDateTimePicker fromdt = RadWindow1.ContentContainer.FindControl("DtFromdate") as RadDateTimePicker;
        DateTime dtfrom = fromdt.SelectedDate.Value;
        RadDateTimePicker todt = RadWindow1.ContentContainer.FindControl("DtTodate") as RadDateTimePicker;
        DateTime dtto = todt.SelectedDate.Value;
when the cursor passes dtfrom, it is raising an null exception.

Hello,

Have you examined this onilne demo on accessing controls from the ContentTemplate of the RadWIndow: http://demos.telerik.com/aspnet-ajax/window/examples/contenttemplatevsnavigateurl/defaultcs.aspx? It shows how you can access them on the server.

Nevertheless, for your convenience I am attaching here a sample page build on top of your code that uses the selected dates (you can see it in the attached video as well).  You can use this as base for your further development.


Kind regards,

HI,
yes i have seen the onilne demos. 
The problem is i can not access the controls inside the content template of rad window from .cs page.


thank you,
phani.

Hi Phani,

Could you share the code you are using and that is not working? Have you taken a look at this help article that also explains how to access the controls inside the ContentTemplate? The RadWindow in this case is just an INaming container and does not require anything more then any other such container would, e.g. a placeholder in a master page scenario.


All the best,
