Need help understanding dropdownlist within a repeater control

Posted By:      Posted Date: September 25, 2010    Points: 0   Category :ASP.Net

Asp.net 3.5 using code behind

I am using a repeater control. My datasource appears in code behind. I decided to NOT have my listitems populate from the database. I want the user to select a value, send it to the database via an update statement, and then when the user returns to the page (on pageload), have the user's previous selections appear on the screen.

 Please note the following:

  • When I use textboxes and labels, ALL of my data appears within the table of the repeater control. However, when I replaced one of the text boxes (originally used for testing purposes only) with a dropdownlist, I get the following error message 'ddlDDuring' has a SelectedValue which is invalid because it does not exist in the list of items.Parameter name: value
  • My Repeater1_ItemCommandI updates the data within the repeater perfectly.
  • On page load, I want the data from the database to display as the dropdownlist's selected value (or selected item.text).  

 Here is my Asp code

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

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.

ASP.NET DropDownList Web Control, Part 1

Anybody with much experience in ASP has written an include file function for populating the contents of a SELECT dropdown list with entries from a database. Some of the more advanced users have even gone so far as to add caching to their function to reduce database hits for these rarely changing menu options. Naturally, these same techniques are going to be used with ASP.NET, but with a new programming object model. ASP.NET provides a web control, the DropDownList, which can be used for the same purposes as our custom built SELECT tag from Classic ASP.

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

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"

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.

Accessing a row's dropdownlist values AFTER the gridview control is in Edit mode

Hello, I have a gridview control. When it goes into Edit mode, there are 3 dropdownlists in one cell that are populated by separate stored procedures during the RowDataBound event. The 1st dropdownlist's value is used as a parameter to determine what the 2nd dropdownlist is populated with. The 2nd dropdownlist's value is used as a parameter to determine what the 3rd dropdownlist is populated with. Everything works fine when the row is first put into Edit mode. While I'm in Edit mode and I change the selection in the 1st dropdownlist, how do I access the control so I can feed this new parameter to the 2nd dropdownlist? I have the first 2 dropdownlists set for AutoPostBack so that the Page_Load event is fired when the user changes a value. I know how to get access to these controls via the FindControl method when the row is being databound but how do I find the control during the Page_Load event? Thanks for any help!!!   Penny  

Issue with Repeater control.

Hello. I have a Repeater control which contains asp:Button control in ItemTemplate. I want to handle Button's Click event, but when I'm clicking that Button the error is thrown: Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.  For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them.  If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.But on other computer that piece of code is working.I set EnableEventValidation to false, but it's still not working. Please help me out.
