[MSHADroo]

hi

i have a problem whit radgrid in insert/edit mode!
i want in edit and insert mode see a dropdown box for a column that show all avilable string in the database table.

for example:
i have a course table whit courseid and coursename
and lesson table whit lessonid , lessonname , courseid(FK)

the radgrid will show the coursename and lessonname from a innerjoin of tables in datasource

now i want when click on insert or edit , see a dropdown box for coursename that show all avilable row in course table.

Hello Mshad,

 One suggestion is you can use GridDropDownColumn and bind it from code behind in normal and edit/insert mode.Check the following documentation for more details.
Customize/Configure GridDropDownColumn.

Another option is to use DropDownList in EditItemTemplate of GridTemplateColumn(which will show DropDownList in edit/insert mode)
The following documentation shows how to achieve this.
