Show Hide RadComboBox depending on RadioButtonList Selected Value

[gc_0620]

Folks,

Is it possible to show/hide RadComboBox depending on the RadioButtionListSelected Value? For example In RadioButtonList1_SelectedIndexChanged event, if my RadioButtonList1's selected Value = "1", show RadcomboBox (CountryName), else hide the RadComboBox.  Both My RadioButtonList and ComboBox are within EditTemplate of RadGrid.

Below is my code.

Thanks

<telerik:GridTemplateColumn DataField="rblLIST" HeaderText="rbl" UniqueName="rBL">
                        <EditItemTemplate>

                               <asp:RadioButtonList ID="RadioButtonList1" runat="server"  AutoPostBack = "true"
                                onselectedindexchanged="RadioButtonList1_SelectedIndexChanged"
                                RepeatDirection="Horizontal">
                                    <asp:ListItem Text="Yes" Value="1"></asp:ListItem>
                <asp:ListItem Text="No" Value="2"></asp:ListItem>

                            </asp:RadioButtonList>


                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

                    <telerik:GridTemplateColumn DataField="CountryName" HeaderText="Country" UniqueName="CountryName">

                        <ItemTemplate>
                            <asp:Label ID="Label3" runat="server" Text='<%# Eval("CountryName") %>'></asp:Label>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <telerik:RadComboBox ID="rcbCountries"
                                runat="server"
                                AutoPostBack="true"
                                Skin="Vista"
                                DataTextField="Name"
                                DataValueField="CountryID">
                            </telerik:RadComboBox>
                        </EditItemTemplate>
                    </telerik:GridTemplateColumn>

Hi,

I was able to solve it by reading the solution provided by Shinu In this thread. The issue I had is very identical.

The only question I have how I can use NamingContainer property if the RadioButtonList and the RadCombo in childTable GridTableView EditTemplate as opposed to MasterTableView  EditTemplate?   Can I use something like e.Item.OwnerTableView.Name == "Detail" in RadioButton_SelectedIndexChanged event? Please refer to attached .

Thanks

Hello GC_0620,

In the RadioButtonList's SelectedIndexChanged event handler you can not use the arguments ("e" parameter) to get a reference to the item in which the list resides. Instead, you should use a slightly modified approach:

protected void RadioButtonList1_SelectedIndexChanged(Object sender, EventArgs e)
{
    RadioButtonList list = sender as RadioButtonList;
    GridEditableItem item = list.NamingContainer as GridEditableItem;
    if (item.OwnerTableView.Name == "DetailTable1")
    {
        RadComboBox combo = item.FindControl("rcbCountries") as RadComboBox;
        combo.Visible = list.SelectedValue == "1";
    }
}

I hope this helps.
