AJAX :: How To Use Repeater Control

Mar 2, 2010

I need to display a database table in a repeater control but it should be asynchronous and should not be reloaded. When I click the button the next rows need to be appeared without loading. My superior says I need to use Ajax and repeater control. But I only know the synchronous way using something like

Repeater.DataSource();
Repeater.DataBind();

AJAX :: User Control With ModalPopup In A Repeater?

Dec 24, 2010

I have a user control that contains a modal popup extender.

I am using the user control inside of a repeater so it could be shown multiple times on a page.

Everything works fine if the repeater only contains one item.

When there are multiple user controls on the page I get the following error:

"Microsoft JScript runtime error: Sys.InvalidOperationException: Two components with the same id 'PosAdjPopup' can't be added to the application."

How do I get my user control to work with the modal popup extender when it will be used multiple times on a page?

Can I keep the modal popup extender in the user control or do I have to put it on my aspx page and trap the event on the button click?

AJAX :: Animation Extender In A Repeater Control?

Aug 18, 2010

i have an animationExtender control inside a repeater control. targetcontrol of the animationextender is a linkbutton. which should enabled=false when the animation is playing. simply the link button should disabled when the mouseover event of the link button. and after the animation is closed the same link button should be enabled. the problem is this is working fine only for the very first item in the repeater control. i.e. for the first link button in the repeater control when the animation is played the link buttons becomes disabled.(this happens for every link button in the repeater control) but when the animation is closed the first link button becomes enable. but in other link buttons, it remains as disabled.

I'll put the code here:

<asp:Repeater ID="repRecentJobs" runat="server" >
<ItemTemplate>
<div>
<asp:LinkButton runat="server" ID="lnkTitle" Text='<%# Eval("Title") %>' ></asp:LinkButton>
<div><%# Eval("Description") %></div>
<asp:HiddenField runat="server" ID="hfJobId" Value='<%# Eval("Id") %>' />
<asp:LinkButton runat="server" ID="readMore" Text="Read More..." ></asp:LinkButton>
<ajaxToolKit:AnimationExtender ID="AnimationExtender1" runat="server" TargetControlID="readMore">

I have a web page devoloped in visual studio 2008.I have 4 dropdowns and a repeater in the page.based on the selection(search criteria) from the dropdowns the repeater value will change and one dropdown selection will bind values to the other dropdown also.Since the page is causing a lot of postback we decided to implement ajax here.I am yet to learn ajax.which ajax control replace dropdowns?

i have already server side code written on all dropdowns.Please give me a good solution which i can implement in less time and reuse my code.One more update: i have a master page used in the project.I am using update panel of ajax which does not work if i use master page.(That means all the dropdown controls and repeater i put it in update panel.But still page postback occurs.)In a normal page(without master page) it works?

AJAX :: Repeater Data Server Control Has HTMLEditor Inside Is ItemTemplate?

Jun 20, 2010

I am having big trouble with this issue, getting a message from IE that a script is being running for a long time and asking me to stop it myself.

The HTMLEditor seems to be uncomptible with this one.

I am also getting a very weak performance when adding this Ajax control.

I think this control is very heavy, but I'm not sure. If I am not wrong, this post I'm writing is inside the same control and I can see it takes time to load it in my page.

C# - Nested Repeater With Child Repeater In A User Control?

Feb 18, 2011

Edit: I have a working solution already - I would just like to know why my original attempt didn't work. My original attempt is the code below.

I'm using the approach I found here:[URL] 306154 to implement a nested Repeater. Each parent item has one or more children items (the point of having the nested Repeater) with a dropdown horizontally aligned to each child item. In an effort to re-use the nested part of the Repeater I wanted to develop that piece as a user control but couldn't get it to work. I am wondering if it is even possible and if so how?

Here is my user control apsx:

<asp:Repeater ID="NestedRepeater" runat="server">
....
<ItemTemplate>
<tr class="text" id="RepeaterItemRow" runat="server">
<td>
<%#DataBinder.Eval(Container.DataItem, "Name") %>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
<td>
</td>
</tr>
</ItemTemplate>

And here is my code behind for the user control. I noticed when I debugged NestedDataSource was null even though in the parent page load the data is there:

public DataSet NestedDataSource
{
get;
set;
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
NestedRepeater.DataSource = NestedDataSource;
NestedRepeater.DataBind();
}
}

In the parent Repeater in the `<ItemTemplate> I have:

<asp:RepUC ID="NestRep" runat="server" NestedDataSource='<%#((DataRowView)Container.DataItem).Row.GetChildRows("nestedrel") %>'>

And finally the page code behind:

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BuildWBS();
}
}
private void BuildPage()
{
DataSet ds = new DataSet();
ds = DataAccessLayer.GetData("System");
ds.Relations.Add("nestedrel", ds.Tables[0].Columns["Id"], ds.Tables[1].Columns["ParentId"]);
ParentRepeater.DataSource = ds;
ParentRepeater.DataBind();
}

The page loads but nothing relating to the repeater appears on the screen. So, can you see anything wrong with what I have? Is the way I tried doing this even possible?

C# - Repeater Within Repeater (ajax Based Web App) - Cannot Use Any Postback Methods

Jun 23, 2010

For the solution, I cannot use any postback methods, because this is all working through ajax. The solution need to be implemented in the asp.net code. I have a List<WebPage> that contains a list of Links (List<Link>) and I need for all the links to bind repetitive information such as page title, id, url. Here is my current repeater.

<div id="result">
<asp:Repeater runat="server" id="results">
<Itemtemplate>
<asp:Repeater runat="server" datasource='<%# Eval("Links") %>'>
<Itemtemplate>
<tr class="gradeX odd">
<td><%# Eval("Id") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("Title") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("Url") %></td> //property of WebPage (part of results repeater)
<td><%# Eval("URL") %></td>//Property of Link
<td><%# Eval("URLType") %></td> //Property of Link
<td><%# Eval("URLState") %></td> //Property of Link
</tr>
</Itemtemplate>
</asp:Repeater>
</Itemtemplate>
</asp:Repeater>
</div>

of course this doesnt work, how can i do this?

C# - How To Expose A Repeater's Templates From Another Control That Contains The Repeater

Sep 30, 2010

If I have a custom user control (say, MyCustomControl.ascx) which contains a number of other controls including a repeater, is there any way to expose that repeater's templates as templates for MyCustomControl?

For example, I would want to be able to do this:

[code]....

There could potentially be more than one repeater or other templated controls within the parent control, in which case I would like to be able to expose all of those templates for all of the controls in the same way.

My first thought was to simply expose the repeater's templates as ITemplate properties on MyCustomControl, but that didn't work since there's no (obvious) way to access the repeater's DataItem from the templates doing it that way.
