more radiobutton-repeater problems

Posted By:      Posted Date: September 23, 2010    Points: 0   Category :ASP.Net
 

I'm using radio buttons in a repeater control.  I don't think I can use a radiobutton list.  I'm displaying one or two images in a table.  The table has three image cells, but only one or two of them can display an image, never all three.  I only want the radio buttons to be displayed if there are two images, and only in the two cells that contain the images.  if this can be duplicated with a radiobutton list, I'm all ears.

I have all this working by using an array list to populate the repeater.  The aray list includes a visible property that gets passed to the radio buttons.  I've managed to Google a solution to the radio group problem.  I though I had my issues resolved and was ready to move on to the rest of the coding but then I noticed another problem.

None of the radio buttons are initially checked.  If I run the page, check a radio button, click on the link button, the fact that I check one of the radio buttons doesn't register in the Repeater1_ItemCommand.  All the radio buttons show checked = false.  I don't want anything checked initially, but I did set one as checked = true to start to see what happens.  In the Repeater1_ItemCommand event, the radio buttons maintain their initial values, no matter what I do when the page runs.

Help, new job on the line, repeater problems

  
I have a presentation to the CFO in two hours. I can't get a nested repeater control to work right, something to do with teh placement of the <table> tags I think. The first repeater first section works fine, then the child repeater shows the first child section right, but the next section of the parent repeater loses all the formatting applied at the parent table. I've tried vaious permutations of where to place the closing table tag of the outer and the inner and get different results, but never the right results. Here is my current code: < asp:Repeater ID="Repeater1" runat="server" EnableViewState="false" OnItemDataBound="ShowVested">   <HeaderTemplate>   <table cellpadding="3" cellspacing="2" style="border: solid 1px black;background:#b8ccd4">   <tr style="font-size:small">   <th style="width:100px"> Option ID </th>   <th style="width:100px"> Option Date </th>   <th style="width:100px"> Option Price </th>   <th style="width:100px"> Num. Shares </th>   <th style="width:130px"> Shares Exercised </th>   <

Problems with Repeater Control, Update Panel and the Toolkit controls

  

Hi Guys,

 

Having a bit of an issue with the Toolkit controls.

I have a Repeater Control nested inside the Update panel, the repeater item template contains a multiview control allowing users to flick through seperate bits of information. This was working fine the async update was perfect, no issues.

I have then decided to include the rating control to one of the views. problem is now everytime i want to change the view it causes the whole page to postback.  

Attached is the code.

Any help is much appreciated


Use jQuery and ASP.NET AJAX to build a client side Repeater

  
By sending only data to the client, you can profoundly reduce the size of what you send and see a substantial increase in performance. You also allow yourself the ability to easily add features like light-weight sorting and paging on the client. This can not only improve your users' experience, but reduce server load and bandwidth requirements.

You also allow yourself the ability to easily add features like light-weight sorting and paging on the client. This can not only improve your users' experience, but reduce server load and bandwidth requirements.

To that end, I'm going to walk you through these four steps to effectively implementing a client side Repeater, using ASP.NET AJAX and jQuery:

ASP.NET Repeater Combined with jQuery FAQ Plugin Demo

  
The plugin is really straight forward. You just have to add your FAQ items in a header element such as an h2 and content sections in spans. This could be done in a pure HTML page or the FAQ items and content could be pulled from a database or XML file like I did in the download. Once the markup is built, the plugin does the rest. It will hide the content sections, add click events to the headers to open and close the content sections, toggle the plus/minus symbols and build the index shown on the right if you want.

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.

Displaying Data using ASP.NET 2.0 Repeater and C#

  
This tutorial will show you how to display data using the .NET Repeater Control, ASP.NET 2.0 and C#.NET


The Repeater control is a powerful tool and is easy to use.

First, you will need to import the System.Data.SqlClient namespace.

Hide a repeater in ASP.NET C# if the DataSource contains no items?

  
I have an ASP.NET page that uses a repeater nested within another repeater to generate a listing of data. It's to the effect of the following:
In the (C#) code-behind I'm basically using LINQ to pull a listing of information from an XML document and bind that information to the first repeater.

Searching for the answer to this, it seems the method is to determine whether the data for the nested repeater is empty. If it is, then you set the visibility of the repeater to false.

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.

Creating an AJAX Repeater in ASP.NET MVC

  
The "TaskList" is a tried an true example of the most basic thing that you can do in any framework. Unfortunately, I had some problems finding a really good example of all the steps necessary to get a task list to work in ASP.NET MVC 1.0.

Top .NET Performance Problems and how to avoid them

  
Every time I work with one of our .NET customers to help them with managing their application performance I come across the same problems as seen with other clients before: lots of ADO.NET queries, many hidden exceptions in core or 3rd party .NET libraries, slow 3rd party components, inefficient custom code

Use Jquery with repeater, gridview, datagrid

  
Before we talk about jquery inside any itemtemplate (repeater, gridview, datagrid), we need to understand the basic use of jquery functions

RadioButton inside GridView, How to get it work as normal

  
Did you tried before to drag a RadioButton control inside a Gridivew templatefield, and then you attempt to select these RadioButtons , you will notice that the behavior of RadioButton control will be changed and it will work just like the behavior of checkbox control! the user will be able to select more than one radiobutton in the grid!

RadioButton Groups, Table Rows And NamingContainers in asp.net

  
The RadioButtonList. Very handy for inviting users to select just one item from a list although because of the screen real estate it takes up, used less and less in favour of the DropDownList. In plain HTML, the browser knows to enforce the unique selected value amongst a list of radio buttons because they all have the same value for their name attributes.

RadioButton Groups, Table Rows And NamingContainers

  
(In which AJAX-enhanced CheckBoxes become more useful than RadioButtons but inheritance saves the day, and a simple RadioButton-derived control establishes the purpose of a control's naming container)

The radiobutton control

  
The and Controls
In HTML, radio buttons are used when we need to make multiple sets of choices available, but we want the user to select only one of them. If they click on a second selection after making a first, the first selection is removed and replaced by the second. Radio buttons are implemented in HTML using the tag, and setting the type attribute to radio. Every radio button on the page needs to have its own tag. Each radio button within a particular group must have the same name attribute.
