I have two RadComboBox

1. Single Column Combo box
2. Multi Column Combo box

The scenario is when i pick a value from combobox1 that value will use as parameter
for combobox2 whereas combobox2 is a multi column....to filter the items of combobox2 that are related to
the value of combobox1

ex.
(combobox1 items)
*apple
*tuna
*orange
*berry

(when i pick "tuna")

then when i click the combox2 dropdown it will show all related data from the value of combobox1 where is "tuna"

results of combobox2:
ID Description Price Product
----------------------------------------------------------------------------
12 Big 102222 tuna
13 Small 100000 tuna
14 Medium 111000 tuna
15 Clean 345545 tuna

Hi Huejii,

Please have a look into the following full code I tried which works fine at my end.

ASPX:
<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
    <Items>
        <telerik:RadComboBoxItem Text="Select" runat="server" />
        <telerik:RadComboBoxItem Text="India" runat="server" />
        <telerik:RadComboBoxItem Text="Australia" runat="server" />
    </Items>
</telerik:RadComboBox>
<telerik:RadComboBox runat="server" ID="RadComboBox2" Height="190px" Width="420px"
    EmptyMessage="Select">
    <HeaderTemplate>
        <ul>
            <li class="col1">City Name</li>
            <li class="col2">Country Name</li>
        </ul>
    </HeaderTemplate>
    <ItemTemplate>
        <ul>
            <li class="col1">
                <%# DataBinder.Eval(Container.DataItem, "Cityname")%></li>
            <li class="col2">
                <%# DataBinder.Eval(Container.DataItem, "Countryname")%></li>
        </ul>
    </ItemTemplate>
</telerik:RadComboBox>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>">
</asp:SqlDataSource>

CSS:
<style type="text/css">
    .multipleRowsColumns .rcbItem, .multipleRowsColumns .rcbHovered
    {
        float: left;
        margin: 0 1px;
        min-height: 13px;
        overflow: hidden;
        padding: 2px 19px 2px 6px;
        width: 125px;
    }
    .col1, .col2
    {
        margin: 0;
        padding: 0 5px 0 0;
        width: 110px;
        line-height: 14px;
        float: left;
    }
</style>

C#:
protected void RadComboBox1_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
{
    string selectedItem = RadComboBox1.SelectedItem.Text;
    if (selectedItem.Equals("Select"))
    {
        RadComboBox2.Items.Clear();
    }
    else
    {
        string selectquery = "select Cityname, Countryname FROM City where Countryname='" + selectedItem + "'";
        SqlDataSource1.SelectCommand = selectquery;
        RadComboBox2.DataSourceID = "SqlDataSource1";
        RadComboBox2.DataTextField = "Cityname";
        RadComboBox2.DataBind();
    }
}

Thanks,
Shinu.

Hi huejiitech,

Please try the following code snippet I tried to display the selected row values of a multicolumn RadComboBox in RadTextBox on OnClientSelectedIndexChanged event.

ASPX:
<asp:Label ID="Label1" runat="server" Text="City Name:">
</asp:Label>
<telerik:RadTextBox ID="RadTextBox1" runat="server">
</telerik:RadTextBox>
<br />
<asp:Label ID="Label2" runat="server" Text="Country Name:">
</asp:Label>
<telerik:RadTextBox ID="RadTextBox2" runat="server">
</telerik:RadTextBox>

JavaScript:
<script type="text/javascript">
    function OnClientSelectedIndexChanged1(sender, args) {
        var cityname = $find("<%=RadTextBox1.ClientID %>");
        var countryname = $find("<%=RadTextBox2.ClientID %>");
        var selecetditem = args.get_item().get_textElement().innerText;
        var selectedvalue = selecetditem.split(" ");
        cityname.set_value(selectedvalue[0]);
        countryname.set_value(selectedvalue[1]);
    }
</script>

Thanks,
Shinu.
