Combobox in gridview

[MGrassman]

Are there any examples on how to use a combo box as a column editor in the gridview.  I would need the example to show how to use the value of the column as the selected value of the combo box that is databound to lookup source other then the gridview.

Found Solution

New Question
How do I use the GridViewComboBoxEditor control.  The current implementation I'm using shows the combobox at all times.  I would like to only show the combobox when the cell is in edit mode.  Sort of like how a datetime value works. 

Thanks,

Could you show this with a datasource that has a recid and display value.  Also can you not use the autogenerate columns.  I get the ddl to show my list when I edit it but the display value of the dataitem is a guid and not the string value.

Thanks,

Searching for help resulting in obsolete things.
so how do you set RadComboBox for a column in a Gridview by C# code behind.

Hi,

You can create your own column, override CreateCellElement/CreateCellEditElement and return desired control similar to this post:

The popup of the combobox is adapting to what it sees in size
Here's the code of my method :

GridViewComboBoxColumn NewColumn = new GridViewComboBoxColumn();
if (FrenchCaption != "")
    NewColumn.Header = FrenchCaption;
else
    NewColumn.Header = EnglishCaption;

NewColumn.IsVisible = IsVisible;
NewColumn.IsReadOnly = IsReadOnly;

if (Width != -1)
    NewColumn.Width = Width;

NewColumn.SortingState = SortingState;
NewColumn.SelectedValueMemberPath = SelectedValueMemberPath;
NewColumn.DisplayMemberPath = DisplayMemberPath;
NewColumn.DataMemberBinding = new System.Windows.Data.Binding(SelectedValueMemberPath);
NewColumn.ItemsSource = ItemsSource;

GridView.Columns.Add(NewColumn);

First could you tell me why you can't since everybody in the world can.  This could help me make sure my videos can really be seen by everybody

Meanwhile.  Here's the direct link to the video : http://gearworld.dyndns.org:8082/ClientBin/Videos/PUBLIC_behaviour.wmv
If you still can't I presume it's something about security.  Add the address in your exceptions.

Let me know

I can't exmplain with a single screenshot.  It needs to be seen as a video.

A RadComboBox in a RadGridView column, once opened, and scrooling, it's adapting to what it sees and the size of the combobox resizes constantly to fit it's visible content.

Hi,

According to our admins the site is down - there are no access restrictions.

You can use however Jing instead.

DOH, I tried to attach but seems your attach system is accepting only images.
You should consider letting attatching zip at least.

Ah well,

Here's another way if nothing works  A downloadable link.
