C# - Update Linqdata Value From Textbox Inside Repeater?
Mar 4, 2011
First of all i have placed my repeater inside a asp:updatepanel. I have tested to set a value where i know the specific row id. This works but i dont know how to do this when i dont know the specific id and i want to be able to update multiple rows at the same time. I have bound my linqdatatable to a repeater. This table contains multiple rows, so the repeater returns a dynamic count of row. I want to be able to edit one of this columns through a textbox that is generated in my repeater. How can i do this ? I guess it has something to do with ItemDataBound ? But i dont get this to work.

Inside the OnItemCreated event (of the repeater), I get the ID of the textbox that I want to bind to the ControlParameter. I realized that using the ID alone was not working. I get a message saying something like "can't find txtBoxName in ControlParameter". I read somewhere that if I view the page source of the browser, then use the value in the Name attribute of the textbox (for the controlId property of the controlParameter), it works. But I also noticed that when I use a textbox outside the repeater, I could just use the ID of the textbox (without having to use page source to get the name, which is different from the ID in the aspx page, of the textbox).

I'm new in asp.net and javascript. I got a problem.
I have a repeater which contains dropdown list in it.
The items in the dropdown list are all the same at fist.
But if i select a item in one dropdown, then the selected item will be deleted in the other dropdown list.
For example
A, B, C, D,E are the five items in dropdown list, and repeater has three lines.
If A is selected in the dropdown list in the first line of repeater, then the dropdown list in the other lines will only have four items to select, they are B, C, D, E.
If then D is selected in the dropdown list in the third line of repeater, then the dropdown list in the second line will only have B, C, E to choose.
I can do this in csharp code, how can i do it in .aspx page?
The performance is not good using csharp code.

I have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.
My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.
So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?

I have a user control that displays a shopping cart in an ecommerce application.
The main cart display is a repeater that renders as a html table. In one of those table columns, there is another repeater to display people associated with the products int he cart (it's a repeater in case there is a line item >1 with multiple people).
I've added an ImageButton that I want to use to change the person associated with the item. At first, when I'd click on it I was getting this error:
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.
So as an experiment I disabled EventValidation on the page (not the control it's self) and now I do not get an error, but I also do not ever hit the breakpoint I set in the innermost repeater's ItemCommand event.
So I wonder how I might do this without disabling EventValidation, because this control will show up on multiple pages and we don't want to edit them all. Also, I'll need to know not only the repeater containing the control's row that the event came from but also the row index of the repeater containg this one. Is this possible?

what changed do I need to make to my code for it to achieve what I'm after.
At the moment I am getting a "cannot cast to type" error message with the below code.
I have also tried calling the ItemDataBound method in with the parent repeater tags and had no errors but when I clicked on the button it would just move back to the top of the page and would not hide or show any data. Also I have made the div style to none but the first record still shows its child but the rest don't.

I've set up a formview with a Linqdata source to allow users to edit records. When I run it, edit data and submit, it blows up and tells me "Linq datasource6 does not support the Select property when the Delete, Insert or Update operations are enabled." I googled that warning and saw a couple of posts on this forum saying the problem is the slect statement has to be removed from the Linq data source for it to allow updates.
But if I remove the select statement then how do I show the user specific info on pageload? plus I thought the two way databind was an advantge of the datasource control.

I have a literal inside each datagrid item. When the datagrid binds I set the literal equal to a small javascript script (a third party source). It works great. when I update my update panel the javascript is lost. I know this is a known issue. From googling they recommend you use:
ScriptMananger.RegisterStartupScript
However this renders the javascript at the bottom of the page. I need it inside my datagrid items. Is there a way that I can register my javascript to my literal control?

Inside a repeater there's a list of addresses ..when address link button is clicked, the address is shown inside of text boxes above repeater with all text boxes greyed out and an Edit button is rendered on the page OUTSIDE the repeater and below the text boxes..Now how do I edit this address ?
I need the AddressID of the address that has been clicked inside the repeater...
when Address link is clicked,DisplayAddress command event is fired inside of repeater's ITemCommand so what I did was assigned "AddressID" generated(when Adress link was clicked inside repeater) to a globally decalred string variable and tried to use that inside my Edit Button's click event so as to fill the Datasource(Method used to fill data source requires AddressID) and do stuff...didnt work
