Multiselect DropDownList Retreive selected items

[Richard]

I'm currently using a multiselect enabled dropdownlist.  How do I retreive the list of 'selected' items in the multiselect dropdownlist?

Thanks.

Never Mind.  I figured it out.  If anyone is interested in seeing the solution, please ask in a reply and I'll post the code.

Thx.

Hi Richard,

Thank you for writing.

By default RadDropDownList control does not support multiple selection due to Close operation on mouse click.

We will be glad if you share your solution with community.

Richard,

I would like to see your code please.

[Richard]

GetProjectList = ""
Dim intCount As Integer = 0

For intCount = 0 To (Me.cboPinProject.EditorControl.SelectedRows.Count - 1)
   GetProjectList = GetProjectList & "'" & Me.cboPinProject.EditorControl.SelectedRows.Item(intCount).Cells(0).Value & "',"
Next intCount

GetProjectList = Mid(GetProjectList, 1, GetProjectList.Length - 1)

 

 

In the above code, I initialize a string variable 'GetProjectList'.  I also initialize a loop counter 'intCount'
Then I loop through the 'Me.cboPinProject.EditorControl.SelectedRows.Count-1'
In the loop I can reference the 'Me.cboPinProject.EditorControl.SelectedRows.Item(intCount).Cells(0).Value'

Note:  'cboPinProject' is the name of the dropdownlist  and ...Cells(0) is a reference to the first column in the dropdownlist  (my dropdownlist has two columns)

Hi Richard,

By looking at your code I can assume that you are using RadMultiColumnComboBox. In fact it also does not support multiple row selection. However, you can work around this limitation by using a RadDropDownButton and hosting RadGridView as a child item. Please consider the following code snippet:

RadGridView grid = newRadGridView();
grid.BindingContext = newSystem.Windows.Forms.BindingContext();
grid.DataSource = table;
grid.Size = newSystem.Drawing.Size(200, 200);

RadDropDownButton menu = newRadDropDownButton();
menu.Text = "DropDown";
menu.Items.Add(newRadMenuHostItem(grid));
menu.Location = newPoint(10, 10);
menu.Size = newSize(100, 20);
this.Controls.Add(menu);

If you have further questions, do not hesitate to ask.
 
Best wishes,
