How to automatically start scrolling from the bottom when a page is first opened

Hey there! I'm currently working on a social network service using asp.net/c#, and I've run into some issues with message sending.

When I start to send a message, the scroll displays like this. However, when I hit "send message," it shows the old messages first and the scroll is at the top. I actually want the newer messages to be shown first when the page loads, meaning that the new messages should appear at the top of the page.

Here are my ASPX codes:

<div style=" overflow-y:auto; height:368px; margin-top: -50px; border-top-style: groove; border-right-style: groove; border-left-style: groove; width: 602px; margin-left: 0px;" >      
              <asp:Repeater runat="server" ID="Repeater1" >
 <ItemTemplate>




     <div style="border-top: thin none #BBCEB3; border-bottom: thin none #BBCEB3; padding: 10px;  width: 548px; margin-top: -10px; right: 10px; left: 10px; border-left-width: thin; margin-left: 15px; background-color: #fffff0; border-left-color: #BBCEB3; border-right-color: #BBCEB3; border-top-style: groove; border-bottom-style: groove;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
                    <br />
                    <div style="width: 58px; height: 40px">
                    <asp:Image ID="Image2" runat="server" Height="59px" ImageAlign="Top" ImageUrl='<%#Eval("SProfilePic") %> ' Width="55px" />
                        </div>
                    <div style="width: 307px;  margin-left: 65px; margin-top: -60px">
                        <asp:Label ID="Label6" runat="server" Font-Bold="True" Font-Names="Arial" ForeColor="#000066"><%#Eval("SenderName") %> </asp:Label>
                    </div>
                    <div id="status" style=" width: 461px; margin-left: 78px; margin-top: 11px;">&nbsp;<asp:Label ID="Label7" runat="server" Font-Italic="False" ForeColor="Black" Font-Size="Medium"><%#Eval("Messages") %> </asp:Label>
                    </div>
                    &nbsp;<div style="margin-left: 400px; background-color: #C0C0C0;">
                        <asp:Label ID="Label11" runat="server"  Text="" Font-Size="Small"><%#Eval("Time") %> </asp:Label>
                    </div>
                </div>

Answer №1

Here is an example of how to put a server controller:

<asp:Button ID="BtnOutside" runat="server" Text="Random" style="margin-left:-999px;" />

After that, you can use:

Page.SetFocus(Me.BtnOutside.ClientID);

This will give focus to the button even though it is not visible due to the negative margin. It should also bring the scroll bar to the bottom.

Answer №2

If you want to emphasize a specific element in your code, feel free to insert this snippet wherever needed.

Feel free to use this multiple times within the same code set by simply adjusting the "ID" parameter.

<asp:Button ID="FocusBottom" runat="server" Text="Random" style="margin-left:-999px;"

When the button is clicked or any other event occurs, utilize the following:

Page.SetFocus(FocusBottom);

Replace the (#######) with the desired "ID" for reference.
