Is there any way we can set Selected Items or Checked Items in a multiselect RadComboBox ?. I want to set value on postback from server.

I tried following code but that works only if it is not a multiselect RadComboBox.

Radbox1.SelectedValue = "123"

My front end code.

<telerik:RadComboBox ID="Radbox1" runat="server" CheckBoxes="true" EnableCheckAllItemsCheckBox="true" Width="300" Height="200" AutoPostBack="True" OnSelectedIndexChanged="Radbox1_SelectedIndexChanged" />

I have value in Radbox1 which will be populated from database.

Thanks, Rahul

When the Radcombobox is set to allow multiple selections via the checkboxes, you must use each items checked property.

I use a list here to simulate the items that I wish to have marked on postback. You could have this list pre-populated or it could even be loaded from a database:
