Set "Selected Item" in multiselect RadComboBox

[Rahul]

Hi guys,

Is there any way we can set Selected Items or Checked Items in a multiselect RadComboBox ?.

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

RadComboBox.SelectedValue = "123"

Edit : Also I am setting value on post back in vb.net

Thanks,
Rahul

Hi Rahul,

I suppose you want to set the SelectedItem in a RadComboBox with CheckBoxes property is set to true. Following is the sample code that I tried to set the SelectedItem in a multiselect RadComboBox.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server" CheckBoxes="true">
  <Items>
    ..........
  </Items>
</telerik:RadComboBox>
<asp:Button ID="btn" runat="server" OnClick="btn_Click" />

VB:

Protected Sub btn_Click(sender As Object, e As EventArgs)
    RadComboBox1.SelectedValue = "123"
    RadComboBox1.SelectedItem.Checked = True
End Sub

Hope this helps.

Regards,
Princy.

Hi,

Try the following code snippet to set selected items in a multiselect RadCombobox.

VB:

Protected Sub grid1_ItemDataBound(sender As Object, e As GridItemEventArgs)
 For Each item As GridDataItem In grid1.MasterTableView.Items
  Dim RadComboBox1 As RadComboBox = DirectCast(item.FindControl("RadComboBox1"), RadComboBox)
   For index As Integer = 0 To 4
    RadComboBox1.SelectedValue =RadComboBox1.Items(index).Value
    RadComboBox1.SelectedItem.Checked = True
  Next
 Next
End Sub

Thanks,
Princy.
