How to refresh/repopulate the Dropdown

[Hamayun Khan]

Hi

Basically I m PHP developer but Now i have project in asp.net 2005. I m new to ASP.NET 2005. Even I have no experience of the earlier versions of asp.net.
At this point I need some help for my registration page.

In my registration page I have a dropdown populated from database. there is another dropdown populated from database based on the selected value from the first one. The first time when page is loaded both the dropdowns are populated successfully. Now what i want is that when I select next value from the first dropdown then the second one must repopulate based on selected value. I don't want to post back the page but only want to refresh the specific area.

looking forward for help.
Thanks

If you are wanting a partial page update then AJAX or Javascript are the ways to achieve that. I would lean toward using AJAX because of the readily available controls in the AJAX control toolkit.

See the following video tutorial on how to use the AJAX CascadingDropDownListExtender.

I m using Visual Web Developer 2005
when I try to run the ajax control tool kit solution. I get the following error

the application for the project 'ajaxcontroltoolkit path/templatevsi.csproj' is not installed.
When i open the Ajaxcontroltoolkit.csproj in text mode the following line

<SccProjectName></SccProjectName>

show SccProjectName underline in blue _ _ _ _ _ _ _ _ _

and show the following error

Warning 1 The element 'PropertyGroup' in namespace 'http://schemas.microsoft.com/developer/msbuild/2003' has invalid child element 'SccProjectName' in namespace 'http://schemas.microsoft.com/developer/msbuild/2003'. List of possible elements expected: 'Property' in namespace 'http://schemas.microsoft.com/developer/msbuild/2003'. C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\Ajax Control Kit\AjaxControlToolkit\AjaxControlToolkit.csproj 13 6 Miscellaneous Files

what is the problem I don't understand. I have no experience of ASP.NET. I have started ASP.NET just month before
