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?
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 am using a repeater control and i want to use one more repeater control inside the existing repeater control .
<asp:Repeater ID="Repeater1" runat="server"> <HeaderTemplate> </HeaderTemplate> <ItemTemplate> <!-- start child repeater --> Here I want to use one repater control <!-- end child repeater --> </ItemTemplate> </asp:Repeater>
I have a databound repeater and in this repeater is an imageButton. How do I pass info from the database into the click event? For example, I've got the description, heading and price fields populating labels, but want the id to go into the imagebuttons click event in order to build a querystring.
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:
I have a Repeater cotnrol inside GridView row. I have a one object data source for gridview and one one object data source for repeater control.The select parametar for object data source for Repeater control is the Gridview data key for that row. I set this parametar each time GirdView row is created,and it works fine only when GirdView page size is set to one. When it is set to more that one data bound to repeater is the same for each row. It is from the last row.
I have a Repeater who should show some data from my ms.sql server. But all code inside the Repater is not shown on my .aspx page. What am i doing wrong. I have a similar Repeater on another page and there it works fine.
I am trying to follow this tutorial(out of date) but the simplest I can find and understand to put a repeater or datagrid inside of a datalist.http://www.tutorialized.com/view/tutorial/DataGrid-inside-a-DataGrid/13926I get hung up in the cs part. Can I just add a sql datasource to the aspx page then call it from the cs like this somehow...my
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.
I have a GridView inside a repeater, and for all the GridView events such as ItemDataBound, etc. I can't just use the same because it doesn't recognize it. I know I have to use FindControl and type in the ID, but how?
i have a repeater that displays data from a SQL Server Database. I also want to display an int from the database for the specific item and allow the user to add 1 to the value of that int by clicking a button (almost like a pole). It would work similiar to a 'like' button on Facebook.e.g.
