Question

Here is my code:

<telerik:RadComboBox ID="ddlServicesRequested" runat="server" DataValueField="Value" DataTextField="Text" Skin="Vista" OnClientSelectedIndexChanging="setQtyReq"></telerik:RadComboBox>

function setQtyReq(combo, eventArgs) {
var Combo = $find("<%= ddlServicesRequested.ClientID %>");
var index= eventArgs.get_item().get_index();
}

Me.ddlServicesRequested.Items.Insert(0, New RadComboBoxItem("-- Select One --", "0"))
Dim dt1 As DataTable = GetDataTable("myStoredProcedure")
For Each dr As DataRow In dt1.Rows
  Dim rcbi As New RadComboBoxItem()
  rcbi.Text = dr("Text")
  rcbi.Value = dr("Value")
  rcbi.Attributes("Min") = dr("MinQty")
  rcbi.Attributes("Max") = dr("MaxQty")
  Me.ddlServicesRequested.Items.Add(rcbi)
Next

Here I have the radcombobox that is being populated with two custom attributes, Min and Max. When the user selects an item the setQtyReq javascript function get called and I am able to get the radcombobox and the index of the selected item. My problem I am having is that I can’t figure out a way to get the values of the custom attributes. How can I get the values of the custom attributes?

Finally figured out how to do it:

function setQtyReq(combo, eventArgs) {
    var item = eventArgs.get_item();
    var min = item.get_attributes().getAttribute("Min");
    var max = item.get_attributes().getAttribute("Max");
}
