    Hi Guys,

    In my edit form template, I need to open a panel that holds a RadEditor on the conditional selection from a RadComboBox that is also in the edit form template.
    So for example, if the user selects'add extra details' a panel will open with an editor.

    Cheers in advance,

    Hi Jack,

    Please take a look at the sample code snippet to achieve your requirement.

    <EditFormSettings EditFormType="Template">
            <telerik:RadComboBox ID="rcbSelect" runat="server" EmptyMessage="Select" AutoPostBack="true" OnSelectedIndexChanged="rcbSelect_SelectedIndexChanged">
                    <telerik:RadComboBoxItem Text="1" Value="1" />
                    <telerik:RadComboBoxItem Text="2" Value="2" />
            <asp:Panel ID="pnlEditor" runat="server" Visible="false">
                <telerik:RadEditor ID="rEditor" runat="server">

    protected void rcbSelect_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
      RadComboBox rcbselect = (RadComboBox)sender;
      GridEditableItem editItem = (GridEditableItem)rcbselect.NamingContainer;
      //Access the panel in EditForm
      Panel pnlEditor = (Panel)editItem.FindControl("pnlEditor");
      if (rcbselect.SelectedValue == "1")
        pnlEditor.Visible = true;
        pnlEditor.Visible = false;

    Many thanks Shinu,

    I've been here before on this one but got stuck on insert.
    You code does indeed work and for anyone else reading - this worked for me:-

    I tried using Visible='<%#Bind("reqQon") %>' for the panel, which works as expected in edit mode. But in Insert Mode - it could not bind the default value.

    In another thread you were helping in, I found this from J.Hoventer

    Visible='<%# GetDefaultBool(Eval("reqQon")) %>'
    Protected Function GetDefaultBool(ByVal input As Object) As Boolean
            If input Is Nothing OrElse input.ToString() = "" OrElse input.ToString().ToLower() = "false" Then
                Return False
                Return True
            End If
        End Function

    All good now!
