You should be able to create an empty solution and add the existing projects to it.

The project itself usually doesn't contain any more information than references to DLLs and other projects. If all else fails, you could just create new projects and add the source files to it.

What you can do is put the name there in the html part of the dropdownlist(inside the datagrid) at "OnSelectedIndexChanged" and then define it in the code behind. Don't forget to make autopostback property to true.

BTW please use a better subject line. Smile | :)

you try accessing the dropdownlist like this in the event:
DropDownList list = (DropDownList)sender

and then use it.

Actually why you were getting the error because you were not been able to get the control and then was using it that why you getting that object reference.. error.
In you event just set the reference for the dropdownlist and check whether it works or not.
suppose this your method:
public void Test(object sender, System.EventArgs e)
{

DropDownList list = (DropDownList)sender;
string hh = list.SelectedItem.ToString(); //to get the selected string.

}
