As you can see I'm trying to retrieve the controls in my repeater by using FindControlRecursive and when I've extracted the controls and want to tell whats in them I get the profiles in asp.net Membership and it also works but only for the 1 repeating item in my repeater so I need help how to code so it keeps repeating the profiles for each CommentAuthor there is.
Use the Repeater.ItemDataBound Event

I'm using a listview and ajax in an asp.net web form. In part of that form, I display comments, which readers can rate, either positive or negative.
This value isn't updated unless the page is refreshed, is there a way to update the value without the need of refreshing the page?

string name = e.Item.DataItemIndex.ToString();
long commentId = Convert.ToInt64(e.CommandArgument);

if (e.CommandName == "positive")

commentsUser.Add(commentId);
}
}
else
{
if (!searchcomments(commentId))
{

commentsUser.Add(commentId);
}
}
}
Is there anyone who has an idea on how to do this?
This sounds like you are binding (reading the data of your grid) before executing the command. Since the command changes the data, you should rebind the grid or update it in any other way.

protected void rwzPurchase_NextButtonClick1(object sender, WizardEventArgs e)
{
if (rwzPurchase.ActiveStep.Title == "Grower Information")
{
//Here is where I want to change the text of button if we are in this specific step
RadButton button = (RadButton)sender;
button.Text = "test";
this.rwzPurchase.CommandArea.CommandElements.Add(button);
}
}
I have the following snippet of code in my .aspx file, I want the button to send the ID to the code behind.
<%List<Notes> CommentsList = FindNotes(ParentNote.ID); %>
<%foreach (var comment in CommentsList) { %>
<div id="note" class="tierTwo"><p><%: comment.Content %></p><ul><li><%: comment.AddedDate %></li><li>20:29</li><li><%: comment.AddedByName %></li><li>Add comment</li></ul> >
<div id="addComment<%:comment.NoteID%>" class="tierOne" style="display:none">
<asp:TextBox ID="commentreplytext" runat="server" rows="4"> </asp:TextBox>
<asp:HiddenField id="ParentIdReply" value='<%=comment.NoteID%>' runat="server" />
<asp:Button ID="Button2" runat="server" Text="Add" CommandArgument="<%: comment.NoteID%>" OnCommand="Add_Comment" />
</div>
</div>
The code behind currently looks like this
protected void Add_Comment(object sender, CommandEventArgs e)
{
string uniqueNoteID = e.CommandArgument.ToString();
}
The command argument is getting sent to the Add_Comment method but it returns "<%: comment.NoteID%>" rather than the value it represents. This way of retrieving the NoteID value works fine when setting the div id so I don't know why it is causing an issue in the commandArgument.
Unfortunately you can't use <%%> code blocks in .NET controls. It's to do with the order things get rendered in. You'll have to set the CommandArgument in the code behind when you build the page. You could do that if you built the page using a repeater rather than a for each in the page.
<asp:Repeater runat="server" id="repeater1">
<ItemTemplate>
<div id="note" class="tierTwo"><p><%# Eval("Content") %></p><ul>
<li><%# Eval("AddedDate") %></li><li>20:29</li>
<li><%# Eval(AddedByName") %></li><li>
Add comment</li></ul>
<div id='addComment<%# Eval("NoteID") %>' class="tierOne" style="display:none">
<asp:TextBox ID="commentreplytext" runat="server" rows="4"> </asp:TextBox>
<asp:HiddenField id="ParentIdReply" value='<%#Eval("NoteID")%>' runat="server" />
<asp:Button ID="Button2" runat="server" Text="Add" CommandArgument='<%#Eval("NoteID")%>' OnCommand="Add_Comment" />
</div>
</div>
</ItemTemplate>
</asp:Repeater>
.cs page:
repeater1.DataSource = FindNotes(ParentNote.ID);
repeater1.DataBind();
I am using an UpdatePanel to show some controls that are normally hidden.
This is the code that I am using:
<asp:LinkButton runat="server" class="btn blue h27" CausesValidation="false" ID="lnkSuggestArticle"
OnClick="lnkSuggestArticle_Click"><%=Supplier.GetResource("Answers_lnkSuggestArticle")%> <i class="icon icon_next_02 fr"></i></asp:LinkButton>
<asp:UpdatePanel runat="server">
<ContentTemplate>
<div class="infoRequest" id="divSuggestion" runat="server" visible="false">
<br class="clearfix" />
<h3>
Please provide the information you want to see on our support site:</h3>
<br class="clearfix" />
<asp:TextBox runat="server" ID="txtSuggestArticle" Rows="10" ValidationGroup="s" Width="100%"
TextMode="MultiLine"></asp:TextBox>
<div id="divEmailAddress" runat="server" visible="false">
<br />
<h3>
Please enter your email address</h3>
<asp:TextBox runat="server" ID="txtEmailAddress" Rows="1" ValidationGroup="s" CssClass="suggestionEmail"
TextMode="SingleLine"></asp:TextBox>
<br />
</div>
<br />
<asp:Label runat="server" ID="lblSugestedArticleError" ForeColor="Red" Visible="false"></asp:Label>
<asp:Label runat="server" ID="lblMessage" ForeColor="Red"></asp:Label>
<br />
<asp:LinkButton ID="btnSaveSuggestion" ValidationGroup="s" runat="server" OnClick="btnSaveSuggestion_Click"
CssClass="btn blue fr"><%=Supplier.GetResource("createticket_btnSuggest")%> <i class="icon icon_next_02 fr"></i></asp:LinkButton>
<%--<input type="submit" value="Suggest" class="btnSuggest" />--%>
<br />
<br />
<p id="notice" runat="server">
<asp:Label runat="server" ID="lblSuggestionNote" /></p>
</div>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="lnkSuggestArticle" />
</Triggers>
</asp:UpdatePanel>
When the user clicks the lnkSuggestArticle button I execute the following code:
protected void lnkSuggestArticle_Click(object sender, EventArgs e)
{
divSuggestion.Visible = true;
if ((WFSS.DataAccess.Entities.Customer)Session["__currentCustomer"] == null)
{
divEmailAddress.Visible = true;
}
}
But it doesn't update the page. The div still stays hidden when the user clicks the suggest button.
protected void lnkSuggestArticle_Click(object sender, EventArgs e)
{
divSuggestion.Visible = true;
if (Session["__currentCustomer"] == null)
{
divEmailAddress.Visible = true;
}
}
It turns out that there was a bug in Visual Studio. I had commented a piece of code in the aspx file. Turns out even though it appeared to be commented the code still executed which caused another update panel to be added which gave me an error in javascript.
On my MasterPage I have 2 update panels which are surrounded with Panels. Two of them contain 'Details View' controls and some buttons.
On the other hand, I have one UpdatePanel which contains image buttons and link buttons.
The idea is that I'm fetching from the database the messages ( 2 kinds), showing them on the Page. When the user clicks on a button (LinkButton or ImageButton), he or she sees a 'Popup Control'. On the popup control, he or she can see the message details and if needed, cancel them or approve.
Here is where I am stuck. If I remove the ImageButtons from the UpdatePanels, I won't be able to refresh them without a full postback.
Should I have 'popup extensions' in the UpdatePanel with the ImageButtons, but then when I click on the button from 'popup panel' - it disappears ( there is no full postback, it just disappears) - it should just change the DetailsView page.
How do I make it work?
Thanks in advance !
(I need this solution because I want to use a timer to refresh LinkButtons )
here is my code behind :
protected void Page_Load(object sender, EventArgs e)
{
try
{
//here im pulling data from database and binding it with 'details view' controls, its not big deal so i think i don't have to show it?
wyswietl_powiadomienia_o_wydarzeniach();
wyswietl_ilosc_zaproszen_do_przyjaciol();
wyswietl_ilosc_nieodczytanych_wiadomosci();
}
catch (Exception)
{
}
}
protected void ButtonWczesniej_Click(object sender, EventArgs e)
{
DetailsViewEventsRequests.PageIndex = DetailsViewEventsRequests.PageIndex - 1;
ButtonDalej.Enabled = true;
wyswietl_powiadomienia_o_wydarzeniach();
}
protected void ButtonDalej_Click(object sender, EventArgs e)
{
//
DetailsViewEventsRequests.PageIndex = DetailsViewEventsRequests.PageIndex + 1;
ButtonWczesniej.Enabled = true;
wyswietl_powiadomienia_o_wydarzeniach();
}
protected void ButtonInvLeft_Click(object sender, EventArgs e)
{
DetailsViewIfFriends.PageIndex = DetailsViewIfFriends.PageIndex - 1;
}
protected void ButtonInvRight_Click(object sender, EventArgs e)
{
DetailsViewIfFriends.PageIndex = DetailsViewIfFriends.PageIndex + 1;
}

I hope i described it well. Sorry For my weak english and some Polish words in code :)
As i should do at the begining i made this example on empty page and try something else.. mode="Conditional" did the trick.
I should give that code before, not that long one :)
