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

I've done something like this; Machine_Serial_Numbers is a telerik:RadComboBox;
foreach (var machine in bulletinData.Machines)
{
var comboItem = Machine_Serial_Numbers.FindItemByValue(machine.Id.ToString());
if (comboItem != null)
{
comboItem.Checked = true;
}
}
This worked for me.

protected void RadComboBox1_ItemDataBound(object sender, RadComboBoxItemEventArgs e)
{
if ("YourString" == e.Item.Text))
{
e.Item.Checked = true;
}
}
Or
protected void RadComboBox1_ItemDataBound(object sender, RadComboBoxItemEventArgs e)
{
List<String> yourStringList = new List<String>() {"string1","string2"};
if (yourStringList.Contains(e.Item.Text))
{
e.Item.Checked = true;
}
}

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:
