Hi

You can eidit the ddTest_SelectedIndexChanged event like below:

protected void ddTest_SelectedIndexChanged(object sender, EventArgs e)
    {
        if (ddTest.SelectedIndex != 0)
        {
            MultiView1.ActiveViewIndex = Convert.ToInt16(ddTest.SelectedIndex) -1;
        }
    }

Because the  the MultiView's ActiveViewIndex is zero-based index of the active View control within a MultiView control.

Hope it helps.

Since the DropDownList is in a Content page which is also in a Master Page the value for the SelectedIndex will only show 0 (zero) as its value. Does anyone know how I can keep the selected value of the DropDownLists? SelectedIndex when the DropDownList is in a Master Pages Content Page?

Hi,

As your description, your mean is the dropdownlist control is in the master page and the  MultiView is in the content page?

For exampe:

1. Master apge:

 <td style="width: 100px">
    <asp:DropDownList ID="ddTest" runat="server" AutoPostBack="True" OnSelectedIndexChanged="ddTest_SelectedIndexChanged" > 
      <asp:ListItem Value="0" Selected="True">-</asp:ListItem>
      <asp:ListItem Value="1">TEST 1</asp:ListItem>
      <asp:ListItem Value="2">TEST 2</asp:ListItem>
    </asp:DropDownList> 
</td>
<td colspan="2" rowspan="2">
        <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
        </asp:contentplaceholder>
</td>

2. Content page:

<%@ Page Language="C#" MasterPageFile="~/TestMutileView/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="TestMutileView_Default" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
     <asp:MultiView ID="MultiView1" runat="server">
        <asp:View ID="view1" runat="server"> 
            <p>TEST 1</p>
        </asp:view>
        <asp:View ID="view2" runat="server">
            <p>TEST 2</p>
        </asp:View> 
    </asp:MultiView>
</asp:Content>
3.So you can get the do in the Master page codebehind:
 
 protected void ddTest_SelectedIndexChanged(object sender, EventArgs e)
    {
        MultiView mv = (MultiView)this.ContentPlaceHolder1.FindControl("MultiView1");
        if (ddTest.SelectedIndex != 0)
        {
             mv.ActiveViewIndex = Convert.ToInt16(ddTest.SelectedIndex) - 1;
        }
    }
 
   If I misunderstand you, please let me know.           

Actually, the dropdownlist is in the content page

1. Master Page

2. Content Page (viewed in Master Page)

3. DropDownList to control MultiView (in the Content Page)

4. DropDownList SelectedIndex gets forced to 0 (zero) for some reason??????????????????.

5. How can I keep the SelectedIndex which was selected so that I can compare its value?

I found the Problem!!!

There was another Form being used in the body of the Master Page. I still am not sure why it worked in Firefox and not IE, but the problem is solved.

Thank you to everyone who took their time on this issue.
