Hi Experts,
I need assistance using the UpdatePanel and ContentTemplate controls in my ASP.Net application.  The screen still flickers when I tab out of the Text fields?  What am i doing wrong?  I have provided a sample of my code below:


<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode=Conditional>
<ContentTemplate>                                
<asp:DropDownList ID="ddlOrgPortCode" runat="server" Style="z-index: 100; left: 212px;
position: absolute; top: 135px" Width="270px" AutoPostBack="True" OnSelectedIndexChanged="ddlOrgPortCode_SelectedIndexChanged" TabIndex="2">
</asp:DropDownList>                            
</ContentTemplate>    
    
</asp:UpdatePanel>
<br />
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
<ContentTemplate> 
<asp:TextBox ID="txtOrigZone" runat="server" Style="z-index: 101; left: 636px; position: absolute; top: 134px" Width="29px" ReadOnly="True" Visible="False">
</asp:TextBox>
&nbsp;&nbsp;&nbsp;  
</ContentTemplate>  
</asp:UpdatePanel>

- Tell me exactly what is your problem? Try to remove AutoPostBack="True" in the dropdownlist, also post the Page_Load function here so i can have more information.

Below is the info you requested.  I cleaned up the code a little bit and removed the AutoPostBack on my dropdownlists.  Let me know if there is anything else I need to check.  My app is still flickering When I tab from a text box to the DropDownList.

Thanks in advance,

<asp:UpdatePanel ID="UpdatePanel4" runat="server" UpdateMode=Conditional>
   <ContentTemplate> 
   <asp:TextBox ID="txtOrgPostCode" runat="server" Style="z-index: 116; left: 115px; position: absolute; top: 135px" Width="80px" Font-Size="Small" TabIndex="1" onblur="GetLocalInfo()"                                                                      OnTextChanged="txtOrgPostCode_TextChanged" ></asp:TextBox>
   </ContentTemplate>  
</asp:UpdatePanel>

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode=Conditional>
   <ContentTemplate>                                
   <asp:DropDownList ID="ddlOrgPortCode" runat="server" Style="z-index: 100; left: 212px; position: absolute; top: 135px" Width="270px" AutoPostBack="False"                                                                                                  OnSelectedIndexChanged="ddlOrgPortCode_SelectedIndexChanged" TabIndex="2">
   </asp:DropDownList>                            
   </ContentTemplate>        
</asp:UpdatePanel>

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode=Conditional>
   <ContentTemplate> 
   <asp:TextBox ID="txtDestPostCode" runat="server" Style="z-index: 111; left: 115px; position: absolute; top: 160px" Width="80px" TabIndex="3" Font-Size="Small" onblur="GetDestInfo()" 	                   OnTextChanged="txtDestPostCode_TextChanged">
   </asp:TextBox>   
   </ContentTemplate>  
</asp:UpdatePanel>

<asp:UpdatePanel ID="UpdatePanel3" runat="server" UpdateMode=Conditional>
   <ContentTemplate>   
   <asp:DropDownList ID="ddlDestPortCode" runat="server" Style="z-index: 123; left: 212px; position: absolute; top: 160px" Width="270px" AutoPostBack="False"                                                                                                             OnSelectedIndexChanged="ddlDestPortCode_SelectedIndexChanged" TabIndex="4">
   </asp:DropDownList>
   </ContentTemplate>        
</asp:UpdatePanel>







HERE'S THE PAGE LOAD EVENT YOU REQUESTED:

    protected void Page_Load(object sender, EventArgs e)
    {
        this.GetPostBackEventReference(this, string.Empty);

        if (!IsPostBack)
        {
            GetUserEmailAddress();

            TotTable.Visible = false;
            TotalCost.Visible = false;
            ManualTable.Visible = false;
            btnCalcTotal.Visible = false;
            TabGrid.Visible = false;
            GridResults.Visible = false;
            tblLegend.Visible = false;

            GMap1.addGMapUI(new Subgurim.Controles.GMapUI());
            GMap2.addGMapUI(new Subgurim.Controles.GMapUI());

            GMap1.Visible = false;
            GMap2.Visible = false;

            txtOrgPostCode.Focus();
        }
        else
        {
            string eventTarget = (this.Request["__EVENTTARGET"] == null) ?
            string.Empty : this.Request["__EVENTTARGET"];
            string eventArgument = (this.Request["__EVENTARGUMENT"]);

            if (eventTarget == "GetLocalInfo()")
                GetLocalInfo();

            if (eventTarget == "GetDestInfo()")
                GetDestInfo();

            if (eventTarget == "ManPerc()")
                ManPerc();
        }
    }
