I have a radcombobox with AllowMultipleSelection set to true.

When loading a window I want to set the selected items in that combo box from values obtained from a database. But I can't seem to see how the values can be set if I set the ItemsSource to a string[]

 

As an example

      string[] items = new string[] {"1", "2" "3", "4"};
      OptionCombo.ItemsSource = items;

 

Then I want to set "2" and "4" to selected.

 

Thanks

Hello Stefan,

This can be achieved by adding the needed items to the SelectedItems collection of RadComboBox. Please, refer to the following code snippet.
this.combo.SelectedItems.Add(this.items[1]);
this.combo.SelectedItems.Add(this.items[3]);

In case further assistance is needed, feel free to approach me.

Additionally, you can take a look at the Multiple Selection topic of RadCombobox's online help.

Best Regards,

Does not appear to work, SelectedItems count is always 0.
