Conditional control based on repeater content

Posted By:      Posted Date: October 11, 2010    Points: 0   Category :ASP.Net

I have a repeater control with a delete button on each row. I also have a link on the same page (not within the repeater) that I only want to be visible when the repeater contains at least one row.

My problem is that, when the delete button on the final row is clicked, this triggers a postback during which the ItemCommand event is called to process the delete click. However this event is processed after the Page Load event in which I would normally render or not render the conditional link. So I don't know at the time I'm rendering the link whether the user has just deleted the last row.

Am I misunderstanding the chain of events or is there a better way of handling this? Could I, for example, determine from the Sender & e arguments available within the Page_Load event, that the postback has been triggered by clicking the delete button in the repeater? The only other way I can see of dealing with this is to force a second postback once the final row of the repeater has been deleted which seems like overkill.

ASP.NET repeater control - databind with style

even used the inline editing features, which I at the time thought was the coolest way possible to write ASP.NET code ( I managed to write code to hide all other rows and only show the current one - the row being edited). With a nice looking EditTemplate it looked indeed very slick but it really turned into giant and hard to manage code behind files.

Creating Paging for a Repeater Control

A common question is "How do I implement paging within a Repeater?" Although the beauty of the Repeater control is its flexibility, you're on your own for building most functions. ASP.NET 2.0 has included some new controls that provide paging, as does the DataGrid in ASP.NET 1.1. However, this tip shows you how to roll your own paging for a simple data viewer.

Unique content within master page based on conditions met


 Hi all-

I would like to present users with unique content based on certain conditions being met as they land on the home page (default.aspx).  The condition logic will be in the VB code behind Page Load event. The content will go in a content placeholder as specificed from the master page. 

However, the content change wouldn't be something small (ie making a panel or label visible or not) but rather it will be different HTML,  Divs and databound gridview content.  The HTML content will be stored in the database.

Can someone point me in the right direction for best practices on how to accomplish this?


Adding new items to a Repeater control with transitions?



I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. This works fine but there are a couple of requiremnts that are giving me problems and wondered if the the good people of the forum could make some suggestions.

The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions.

I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater. I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.

I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there

Content page control passes as argument to javascript function


Here is the content page:


<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="JavaDynamicCopyValue.aspx.cs" Inherits="JavaDynamicCopyValue" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

 function copyValue(input, output )
   ouput.value = input.value;
   return true;

    <br />
    <br />

Composite Control which contains arbitrary content defined in .aspx of parent and thier ViewState


I want to write own control which can contain other. And I want to define content of the control in the .aspx file where the control is defined. I have written such control. But now I have issue with ViewState of inner controls of my control. The following samle illustrates the issue: I defined two asp:DropDownList ID="ddl1" and ID="ddl2" One of them is inside of my control and other is outside. When posback is occurred asp:DropDownList ID="ddl1 loses state and becomes empty. How to say ASP.net to store state of inner controls defined by this way?


<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyControl.ascx.cs" Inherits="DynamicControls.Controls.MyControl" %>

<div class="box">
    <div class="Header-Left">
        <div class="Header-Right">
            My Control
    <div class="Content">
        <asp:PlaceHolder ID="contentPlace" runat="Server" />

Rendering User Control content


I have a scenario where, the content is:
 ASP.NET Controls
      User Control
 ASP.NET Controls

The entire div code is rendered and is sent at a mail using the code:

Dim sw As New StringWriter()
Dim w As New HtmlTextWriter(sw)
Dim s As String = sw.GetStringBuilder().ToString()

This works fine except that the User Control does not get rendered.

Any way out, so that the User Control content is also rendered ?

Accordion Control Renders Content Incorrectly


Hey Guys i'm using an accordion control with one pane. In all browsers it renders and works fine - except IE8. in IE8, it looks fine at first, but after collapsing and reopening the pane the text in my pane appears garbled. When i zoom in, i can tell it's in the original font, but it's almost as if it's an image that's blow up too big...

Help with updating database with values from Repeater control using c#


Hello, I'm new to ASP.NET 3.5 with C#. I really need some help.

I used a Repeater control to create a simple (editable) list where, when a user logs in, they can edit their list of expenses.  The ASP page works fine.

 My issue is with the code-behind.  I am really confused with how to extract the values from the repeater control. The FindControl method does not seem to be working.  Also, the code I am using resets my 'Amount' values back to 0.00. (0.00 is the amount the user sees when they first encounter the page).

 Here's a portion of the code on the ASP page:

<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1"





<td><asp:Label ID="lblExpId" runat="server"  Text='<%# Bind("ExpId") %>'></asp:Label> </td>

 <td><asp:Textbox ID="lblExpense" runat="server" Width= "190px" Text='<%# Bind("ExpenseName") %>'></asp:Textbox> </td>

 <td><asp:Textbox ID="txtAmount" runat="server" Width= "100px"

XML Repeater Inside Conditional Statement


Hi all,

I'm working on an VB.Net application which have 2 nasted repeaters using xml as data source. I need to add a conditional statement withen the first repeater ItemTemplate as follows:

	<%# IIf(XPath("@type")= 3 , "<html>", "<div id=""tblPages"" runat=""server""><divsub""><h2>"   &  XPath("@title") &  "</h2><ul class="sublinks"><asp:repeater id=""rpPages"" DataSource=""XPathSelect("@page")"" runat=""server""><ItemTemplate><li></li></ItemTemplate></asp:Repeater></ul></div></div>" ) %>

The problem come when I  try to add the

DataSource='<%# XPathSelect("page") %>'

so I get an error.

Does anyone have idea if the above code may work?

thank you

User control with multiple item content

I have a user control that I would like to contain multiple items as its content, similar to the way a <StackPanel> works. I tried using a <ContentPresent/> but it will only let me use a single item as the control's content. What's the best way to go about this? I realize I could just require the user to put a <StackPanel> or <Grid> or similar control as the content of the user control, but i would rather not do that if possible.   I'm not sure if it matters, but this control actually has several content presenters. Some of them will contain a single item and some will contain multiple items.

jQuery Rating Control in Repeater - Not Duplicating per Record

Hi Everyone,There is a similar instance of this @ http://forums.asp.net/p/1380776/2919093.aspx#2919093 However I haven't had a response, maybe due to the age of the topic, but the problem is different in the sense I am not using AJAX Rating Control, I am using radio buttons contained in a Div named Ratings, which is picked up by jQuery to style to radio buttons accordingly. The output is that it will put the stars on the first record but anything after just shows origional unstyled radio buttons. Just thinking off the top of my head, but does anything need to be put in the ItemDataBound event? The jQuery for the stars etc were attained from the link below:http://orkans-tmp.22web.net/star_rating/index.html#demos=&main-menu=0&demo-tabs=3 Here is my code:.ASPX:<%@ Page Language="C#" MasterPageFile="~/Admin/Admin.master" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Admin_Test" Title="Untitled Page" %> <%@ Register Assembly="AjaxControlToolkit" Namespace="AjaxControlToolkit" TagPrefix="asp" %> <asp:Content ID="Content1" ContentPlaceHolderID="CPCHeader" Runat="Server"> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="AdminCPC" Runat="Server"> <asp:R

SharePoint read/recognize a Digital Signature in Word (XML Content Control Mapping)?

I am using Content Control Mapping to pull certain fields from a Word Document and include it as columns when a document is uploaded into a Document Library. We're using MOSS 2007 and Word 2007. It is required that the user digitally signs the document before uploading.  Is there a way to get the signature to appear as a column in a similar fashion?  I'm new to this mapping business, and Google hasn't been much help. I realize I could use the Collect Signatures workflow, but that seems cumbersome to 1) have the user submit it, 2) have an admin open each document and start the workflow and 3) have the user THEN sign the document.  That's more steps than simply manually opening and verifying digital signatures. I figure I'm missing something obvious here.  Any help or ideas would be appreciated.

Creating a volume control slider/setting one template property based on another

So, what I want to do, is to make a volume control that looks like a right angle triangle with the 90 degree angle on the bottom right, and then when you click on it, the area to the left of the selected point is shown in a different color.  In other words, I've created a slider with the right background, what I can't do, is work out how to show the selected area by filling in the triangle.  I have worked out how to bind the height of my triangle on the left to the value of the control, but right now, the rate of rise is exactly half of what I need it to be.  I need to know how to change the template for the area to the left of the selection ( which is the repeat button ) so that the background is twice the height that it is right now.  No matter what size I make the slider, the area is always 1/2 the size it needs to be, so I am sure if I could get it to double inside my template, it would work fine. <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">       <Style x:Key="SliderButtonStyle" TargetType="{x:Type RepeatButton}">         <Setter Property="SnapsToDevicePixels" Value="true"/>         <

Get content of programatically created control before postback

Hi.I have quite a problem here, and hope you can help :)I´ll try to describe the problem in steps, as this might be the easiest to understand:1. Page_Load is called when the page is requested, and calls a BuildTable() method2. The BuildTable method creates a table which contains several textboxes3. the user types some text in these textboxes4. The userthen  changes an item in a Dropdownlist on the page which is intended to change some other content on the page5. Page_Load is called, and afterwards the DropDownListBookingType_SelectedIndexChanged(object sender,EventArgs e) method are called, and the content is changed6. The text the user typed in the programmatically created textbox controls are lost!Now how do I remain this text information? If just the SelectedIndex_changed method was called first, I could save it in session.. But as far as I can tell, all data on the page are discarded when you create a partial postback :(What to do?Thanks alot for your time!
