    RichDropDownList server side onChange event

    Reply Quote
    How do I hook up a server side onChange/selectedIndexChanged event for my custom RichDropDownList?  I have read the example "customize_dropdown.aspx".  That example shows connecting to an existing command "InsertLink".  I need to connect to method within my codebehind class.
     
    I want to be able to select an item from my dropdown list and based on the item selected I will retrieve information from the database and manipulate the Editor.text.
     
    Thank you for you help.

    jscadden,
     
    To add a server control, please use the following example. RichDropDownList doesn't support server side event. You need to use the regular ASP.NET DropDownList:
     
    <asp:DropDownList ID="DropDownList1" runat="server"></asp:DropDownList>

    create/register a custom button (Server Control) to Cute Editor

    How to create/register a custom button (Server Control) so that it can be used in the template?( C# | VB )

    This example demonstrates how easy it can be to add Server Controls to the CuteEditor and register it into Cute Editor toolbar.

    Thank you for your reply.  I have been able to get my dropdown to show up on the toolbar using the above example.  It won't work until you specity the dropdown in the following call.
     
    TemplateItemList="[Bold,Italic]/[World,clients]"
     
    My problem now is that I am not able to get it to fire the SelectedItemChanged event.  I am able to get a button's "click" event to work, but not a dropdown's SelectedItemChanged event.  When I select an item in the dropdown it doesn't change to the selected item.  Can you provide an example of adding a custom serverside dropdown control that responds to an event when selecting an item?
     
    What am I missing?

    End Sub
    </script>

    <html>

    <asp:ListItem>Item 3</asp:ListItem>
    <asp:ListItem>Item 4</asp:ListItem>
    <asp:ListItem>Item 5</asp:ListItem>
    <asp:ListItem>Item 6</asp:ListItem>
    </asp:DropDownList>
    <asp:Button Text="Submit" OnClick="submit" runat="server"/>
    <p><asp:label id="mess" runat="server"/></p>

    Ok.. Firefox was hanging me up.  I am able to get the SelectedIndexChanged event to fire using the arrow keys and enter key on the keyboard.  The DropDownList doesn't respond to mouse clicks when running under FireFox.  Everything seems to function properly under IE 7.  Any suggestions or fixes for FireFox?
     
    Here is a code sample:
    <%@ Page Language="C#" AutoEventWireup="true" %>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <script runat="server" >
        protected override void OnInit(EventArgs args)
        {
            editor.Initializing += new EventHandler(editor_Initializing);
            base.OnInit(args);
        }

        protected void editor_Initializing(object sender, EventArgs e)
        {
            AddClientDropDownList();
        }

        private void AddClientDropDownList()
        {
            DropDownList list = new DropDownList();
            list.AutoPostBack = true;
            list.Items.Add(new ListItem("Clients", "0"));
            list.Items.Add(new ListItem("Microsoft", "1"));
            list.Items.Add(new ListItem("CuteSoft", "2"));
            list.SelectedIndexChanged += new EventHandler(list_SelectedIndexChanged);
            list.CssClass = "CuteEditorDropDown";
            editor.RegisterCustomButton("clients", list);
        }

        void list_SelectedIndexChanged(object sender, EventArgs e)
        {
            editor.Text = "list selected";
        }
    </script>
    <html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
        <title>Untitled Page</title>
    </head>
    <body>
        <form id="form1" runat="server">
       
        <div>
            <CE:Editor id="editor"  Width="100%" Height="600" TemplateItemList="[clients]" runat="server" ></CE:Editor>
        </div>
        </form>
    </body>
    </html>
