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

Nov 12, 2010

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 have a simple user control that I have placed inside a repeater. I want to access it through the ItemDataBound event of the repeater. Here's my code so far:

[Code]....

Not so sure what to do about all of this. I have developed a simple calendar using an XML doc and a repeater. The parent repeater contains a child repeater that lists events based on the date. I have a User Control that has some unique capablities for control the date in a link button. I want the user to click on the User Control and be able to use the information to do something. Bottom line, I want to access the linkbutton inside the repeater.

I'm looking for the correct syntax to get me the last row of a repeater item and use it in a literal below. As you can see I have the item index syntax already. assume that there is a repeater control surrounding the literal already.

I have already bound the data so it will not use obitemdatabound .

<asp:Literal id="Rpt_ItemCount" runat="server"
Text = '<%# (int) DataBinder.Eval(Container, ItemIndex"))%>'></asp:Literal>

Forms Data Controls :: How To Bind A DropDownList Inside A Repeater

Oct 29, 2010

I am new to ASP.NET, trying to learn it. I am using ASP.NET 3.5 with VB for scripting. Also read some books. I just can't figure out how to bind a DropDown List inside a Repeater Control. I saw a few examples but none were clear enough and explained all the details. I want to populate the Drop-Down using values from a Database inside the repeater.

I also read this article [URL] but still can't understand how to bind dropdown in a repeater.

I want to display 2 things inside the Repeater Control.

1. User Selected Values (which comes in the form of an Arraylist) from a previous page using "PostBackUrl" method.

2. Then allow users to select values from a Dropdown list corresponding to each design code they selected on previous page. (the dropdown values here must come from a backend db)

Also, I want to control the number or rows displayed inside the repeater control. It should be equal to the number of "design codes" selected by the user on a previous page.

Here is my code so far ....

ASPX Code:
