I looked into it a bit farther and the postback function seems to be missing from the javascript for the page. I switched to MagicAjax and now everything works the way it is supposed to.
I'm a little too deep to make any switches. :-)
hello.
let me see if i understand what's going: you have a multiview control and in one of the views you have several linkbuttons. clicking on the button doesn't postback and from what you say, the problem is that the postback method isn't in the page.
so, i assume that the view that has the buttons isn't the initial view and that you don't have anything on that page that is able to start a postback. if this is your scenario, then the problem you're seeing is a bug of the atlas platform. the problem is that during partial postbacks, the __doPostBack is discarded and isn't added on the client side because the platform assumes that it is alread there.
an easy workaround is to add a button to the page (with the usesubmitbehavior set to false) and hide it (by using the css display property).btw, the reason everything worked with buttons is because on asp.net 2, they are inserted as submit buttons by default (<input type="submit">).
I guess my problem is a little simplier. I have two LinkButton objects inside of a Panel object, which is then contained in an UpdatePanel. To test, I added a Button object and it does postback as expected. The LinkButtons do not postback and I cannot figure out why. Is this a known issue with Atlas?
hello.
it looks like you can reproduce the problem with a simple page...can you post that page here?
The problem was the panel being set to "visible = false" up front. I have a link on the page that sets it to be visible though. Once that link is clicked and the panel is visible, the two LinkButtons don't fire the postbacks. Instead, when I started up with visible being set to true, everything worked just fine. So I just had to do a little z-index magic to get around setting it to "visible = false" to start. Kind of weird I can't start with that panel not being visible.
hello.
well, that's the problem i've described in my previous post. the same thing happens when you put the button inside a panel and set it its visible property to false during the initial rendering of the page. in these cases, when you don't have any other controls that use the __doPostBack method, the page won't work correctly when you use partial postbacks because even though the server side sends the __doPostBack method on the reponse for a partial postback, it'll be discarded by the client framework since it allways assumes that the method was added to the page during its initial rendering.
this is an old bug that i've reported a few months ago, though it still hasn't been solved.
Thank god for this thread, I finally able to solve the problem that I've been trying to solve for days. Your solution does work for panels and/or linkbutton inside the updatepanel. However, when I tried to set the visibility of the panel located outside of the updatepanel to true (initially set to false) by calling a method, it does not work. Any workaround for this? Thanks a bunch!
hello.
are you doing that (changing the visibility of the panel) during a partial postback? if so, then the panel must be inside an updatepanel...
Umm ... well, I don't know .. Am I? Anyhow, this is the code:
<asp:Content ID="Content1" ContentPlaceHolderID="Main" runat="Server"> <cc1:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true"> </cc1:ScriptManager> <div id="comments" class="page"> <table> <tr> <td> <asp:Label ID="Label1" runat="server" Text="Name"></asp:Label></td> <td> <asp:TextBox ID="Nama" runat="server"></asp:TextBox></td> </tr> <tr> <td> <asp:Label ID="Label2" runat="server" Text="Comment" Style="vertical-align: top"></asp:Label></td> <td> <asp:TextBox ID="Komen" runat="server" Height="72px" Width="299px"></asp:TextBox></td> </tr> <tr> <td> <asp:Button ID="Button1" runat="server" OnClick="SubmitComment" Text="Submit" /></td> <td><asp:Label Visible=false ForeColor=red ID=commentError runat=server></asp:Label></td> </tr> </table> <br /> <cc1:UpdatePanel ID="UpdatePanel1" runat="server" Mode="Conditional"> <ContentTemplate> <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="SqlDataSource1"> <Columns> <asp:BoundField DataField="Name" HeaderText="Name" SortExpression="Name" /> <asp:BoundField DataField="Comment" HeaderText="Comment" SortExpression="Comment" /> <asp:BoundField DataField="Date" HeaderText="Date" SortExpression="Date" /> </Columns> </asp:GridView> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString%>" SelectCommand="SELECT Name, Comment, Date FROM Comments ORDER BY Date DESC"></asp:SqlDataSource> </ContentTemplate> <Triggers> <cc1:ControlEventTrigger ControlID="Button1" EventName="Click" /> </Triggers> </cc1:UpdatePanel> </div></asp:Content>and this is the codebehind that validate the input:
public void SubmitComment(Object sender, EventArgs e) { String dt = DateTime.Now.ToString(); String Name = Nama.Text; String Comment = Komen.Text;if (Name =="" || Comment =="") { commentError.Text ="Please complete all required fields"; commentError.Visible =true; }else {//SOME CODE TO INSERT Name and Comment to database } } So, basically if the user doesn't put either name or comment, the commentError label will be shown up. Should I just put the entire table into update panel? Because when the Button1 is not tied up to the triggers, everything works fine.hello.
well, that's because when button1 is configured as a trigger, the client portion of atlas intercpets the call and performs a partial postback; when you don't do that, you get a full postback. so, you have 2 options: you can put everything inside a panel or you can use two panels.
