I need to access a control inside a repeater and change its properties. To enable it or not. I got an erorr message Object reference not set to an instance of an object. Here is my code inside a method. protected void
rptCAP_ItemDataBound(object sender, RepeaterItemEventArgs e) { LinkButton lnDel = (LinkButton)rptCap.FindControl("lnkDelete"); lnkDel.Enabled = false; //<<<<< this is where the error occur }
I am using a repeater control and i want to use one more repeater control inside the existing repeater control .
Like this:
<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 two dropdownlists inside a repeater. And based on the value I pick in the first dropdownlist the second needs to get populated (both need to be populated from the DB via stored proc). I am adding the code I have so far but it's not complete
When I place the repeater inside a user control INSIDE ANOTHER user control and onto the page this works - the property is correctly set, if I inspect it inside the EnsureChildControls() method of the custom control the composite control's Value propertyis set to Eval("value") as intended.
I have a repeater control on my page. Here's my code:
[Code]....
I would like to change a background color of the item's <div> when user checks the chechbox. I have an event handler for CheckedChange event but I don't know how can I get access to this div from the event handler.
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?
After much research, no solution can be found to do what I want by combining these two controls. Currently, I have a repeater control which, in page_load, takes the querystring and queries the database accordingly, puts the resulst in a datatable, and binds the datatable to the repeater. Everything works fine, no problem there. It's just that I have many columns coming from the query and there are many rows as well. So, I thought it would be easier to incorporate the accordion, so that the header of each accordion pane would show some unique fields (name, whatever...) as the header, and the rest of the many fields in the content. This way, there would be many closed accordion panes showing the name from the row returned. If the pane is clicked, the pane would open and show the rest of the results.
The problems I've had are that the repeater is not accessible from the code behind if it is inside the accordion. But I'm sure I wasn't doing it right anyways. I'm just trying to have an accordion that has as many panes as there are results from a datasource. If there is something other than a repeater that you can suggest, or the correct way to incorporate the repeater in the accordion to do what I want, suggest whatever! I just need to format how the results display how I want, unlike a gridview (I used tables in my normal repeater, and that worked fine, I just need to get that repeater to work inside of the accordion).
(and I know this isn't the section to ask about the accordion, but what is the AccordionExtender? It's not in the toolbox, and I can't find much online. It won't be recognized by Visual Studio, so I don't know what to do. If I could get that, I feel like it could solve my problem, as I found a possible solution online) I don't need to post my code, as it's a simple repeater, and trying to integrate it within the accordion isn't working no matter which way I try since I can't DataBind() in the codebehind. And yes, I tried to FindControl within the accordion but it wouldn't find the 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.
I want to create an accordion inside a gridview with the following functionality:
The user will only see one field of the gridview initially, the ProductCategoryID. When the page loads it will only query the ProductCategoryID and this will be the only field displayed.
Next when the user clicks on the accordion to expand it inside the gridview I would like to query the database to get all Products that are part of the ProductCategory. I will query using the ProductCategoryID that is being displayed.
I need to do this for performance issues. The main thing I am looking for is how to query the database once the user expands a given ProductCategoryID.
but now I think of it one thing I need to know: when you bind an accordion to a dataset will it create one pane for each record returned? It might be better to put the gridview inside the accordion. I'm willing to do either, as long as it works
I am trying to bind a DropDownList inside a repeater control to an existing data set (to be able to edit the data) and I have been searching for an answer to this problem for a day and a half now without any luck.
