Apr 12, 2010

I have a problem with my first ASP.NET webpage. Im using ASP.NET 3.5 with VisualStudio 2008 and LINQ to SQL.
To easier communication we take a example from northwind data base. I want to list all the Orders and for each order I want to list all its OrderDetails. I have created a listview (lvOrders) with a LinqDataSource (Order table). Now I have create a new nested listview, for the order details, but I dont know how to load the orderdetails in this nested listview. I have tried to load the orderdetails in the OnItemDataBound of the first listview (lvOrders), but I miss functionatilly like DELETE command on the nested listview (to delete a orderdetail) This is my code:

On code behind:

Forms Data Controls :: ImageButton Inside A Repeater That Is In Another Repeater & Events?

Jan 18, 2010

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?

Forms Data Controls :: Hiding A Repeater Div Using A Link Outside The Repeater?

I'm so confused I wasn't even sure what to make the title so that it would make sense.

Here is what I have:

[code]...

I have links at the top of the page that are the letters A-Z. What I want to do is click on one of the letters, then show only the div IDs that start with that letter. I can't figure out how to do this since I'm dynamically creating the ID names. I had it set up nicely with Javascript and CSS, but the function call was inside the repeater. The layout is changed now, and I don't understand how to make the div ID available outside the repeater.

Forms Data Controls :: Show / Hide A Div In A Nested Repeater By Clicking On A Button Inside Parent Repeater?

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.

Repeater Item Command Won't Fire?

Dec 9, 2010

I have a repeater that is nested within a list view. I bind both and everything works nicely. The problem is that, my repeater has a deleteComment LinkButton which doesn't fire at all!!! I have enabled view state for everything including the page itself. In my code for repeater, my LinkButton Code Looks like this:

<asp:LinkButton ID="lbDeleteComment2" runat="server" CommandArgument='<%# Eval("Id") %>' OnClick="DeleteCommento" Visible="True" EnableViewState="True" CausesValidation="False" CommandName="DeleteCommento" Text="Delete"/>

My problem is that the OnClick Event of lbDeleteComment2 doesn't fire at all. I have been searching for a solution for three days now and no luck.
