Hello I am trying out your Controls

I have a Class named PeopleCollection that contains a People list.

I have a drop down That Contains All Kind Of People Collection adn A Dictornary taht has the
People Collection by their name:

for ex.

PeopleDropdown:

On DropDownLoad()
{ Fill PeopleDictonary with all Kind of People
)

onDrpDownSlectedIndexChange
{
Grid.Datasource=null
Grid.Rebind()
Grid.DataSource = dictonarywithpeople[Combobox.SelectedItem.Text].PeopleList;}
Grid.Rebind()
}
onGridLoad()
{
Grid.DataSource = dictonarywithpeople[Combobox.SelectedItem.Text].PeopleList;}
Grid.DataBind()
}

Hi David,

From your code snippets I see that you are using simple binding for your grid with DataBind() calls. Note that RadGrid features like data editing, filtering, grouping, etc. require advanced binding with NeedDataSource event handling or assigning a data source control for grid items generator.

Please revise your code accordingly to address the issue. You may also be interested in reviewing the online resources linked below which concern data editing:
