and here is my code of web form when i add this control to the web form.

<%@ Register TagPrefix="cc1" Namespace="DropDownWebControl" Assembly="DropDownWebControl" %>
<cc1:SmartDropDown id="SmartDropDown1" style="Z-INDEX: 103; LEFT: 187px; POSITION: absolute; TOP: 259px"
                runat="server" AutoPostBack="True" OnSelectedIndexChanged="SmartDropDown1_SelectedInd exChanged"
                Width="109px">
                <asp:ListItem value="custom">custom</asp:ListItem>
                <asp:ListItem Value="abc">abc</asp:ListItem>
                <asp:ListItem Value="ade">ade</asp:ListItem>
                <asp:ListItem Value="bad">bad</asp:ListItem>
                <asp:ListItem Value="bcd">bcd</asp:ListItem>
            </cc1:SmartDropDown>

and in aspx.cs page ,i have

protected void SmartDropDown1_SelectedIndexChanged(object sender, System.EventArgs e)
        {
            TextBox1.Text=SmartDropDown1.SelectedValue;
        }

Thanks

Nope but i think i need explanation on this code that i have...may be its because of this....

protected virtual void RenderAttributes(HtmlTextWriter writer)
        {
            if (base.ID != null)
            {
                writer.WriteAttribute("id", base.ClientID);
                writer.WriteAttribute("name", this.UniqueID);
            }
            if (!this.Enabled)
                writer.WriteAttribute("Enabled","false");

            writer.WriteAttribute("ParentFormID", this.ClientID);
            if (this.AutoPostBack)
            {
                string sOnChangeCmd = this.Attributes["onchange"];
                if (sOnChangeCmd != null)
                {
                    this.Attributes["onchange"] = (sOnChangeCmd.EndsWith(";")) ? sOnChangeCmd + Page.GetPostBackEventReference(this, String.Empty)+ ";" : sOnChangeCmd + ";" + Page.GetPostBackEventReference(this, String.Empty);
                }
                else
                {
                    this.Attributes.Add("onchange", Page.GetPostBackEventReference(this, String.Empty));
                }
            }
            this.Attributes.Render(writer);
        }

if you look at the GetPostBackEventReference it is returning empty strings.I wonder why?

and another thing that doesnt work in my code is on PreRendor if i add Page.RegisterPostBackScript as in this example , it gives me error that this method is not accessible because of protection level.

and to tell you the truth i am tired and confused now.

Mr Parsons,

I am sorry dont know your name.....:-)
Did you get chance to look into the code i sent you? Any new suggestions.

Thanks
Kamal
