I am using Telerik Rad controls in my project. I have a Rad Calender inside a Repeater.
<asp:Repeater ID="ResultRpt" runat="server">
<ItemTemplate>
<telerik:RadCalendar Style="width: 191px; height: 123px" ID="RadCalendar1" runat="server"
[code]...
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?
I need to list URL records from DB and bind data to repeater, therefore I put hyperlink inside repeater control.
I want to fire 2 events when a Visitor click on hyperlink
1- It Update DB Record that this link clicked one time
2-Open URL in new windows
i wnat to show repater inside datalist with CollapsiblePanelExtender but not work. this is my code

I've done things like
<%# somefunction("string") %>
before in my asp code, calling some public function in the codebehind. But now I'm trying to do this from within a repeater item. The message I receive from the compiler is: "The name 'somefunction' does not exist in the current context." Error 97 The name 'getclass' does not exist in the current context 169
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>
got an example of a repeater inside a repeater (dataBound) code behind?

View 2 RepliesI am using Nested Repeater repeater1 and repeater2 in my project . one button is there inside repeater2 but i cant use that button using e.commandname
so how to use that button and how to write code on it.
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.

View 1 RepliesI am trying to use this solution to access items inside a telerik menu item:
ascx code:
<asp:Label ID="DivLeave" runat="server"></asp:Label>
In the ascx.cs file I run this code to disable the asp label
RadMenuItem expenses = RadMenu1.FindItemByText("Expenses");
Label DivLeave = (Label)expenses.FindControl("DivLeave");
DivLeave.Visible = false;
but I get this error when I try to run the code:
{"Object reference not set to an instance of an object."}
I really need to run this server side as code surrounding the above code does some work server side and it will all fit in neatly...
I'm currently working with a repeater which has some number of drop down lists in it determined by how many items are databound to it. I wanted to add an event to each of these drop down lists in the scenario that a user changes the selected index.
Here is what I have for the repeater (Note that I am doing all of the databinding in the codebhind.):
[Code]....
I am setting the OnTextChanged event here, however I did some experimenting with using the different events. I found that my method will not run when I am using the OnTextChanged or OnSelectedIndexChanged events. However, if I use some other events like OnLoad or OnPreRender, the method I have it set to actually runs. So in short, why is it that when I put this drop down list in the repeater only SOME of the events seem to work?
There are reports of this kind of problem in their own forum Telerik, and some comment saying it is not possible. That only works with InputManager components. But in my case, I need to have both features, I need to use components from Telerik () with validations. Whether using Ajax or some other technology or method?
View 1 RepliesI have a Custom Repeater control that inherits from Repeater and has paging functionality, however when I click the next page button the first time it refreshes the control but does not change the page, if I click it again after that it changes page perfectly. I know what the issue is, when I click the next button it does a postback, then the data is bound to the repeater, and then after that the NextButton Event is handled.
Is there any way I can change the order of the page load events?? Or force the repeater to reload again after the event is handled?? I've included my Custom Repeater class bellow:
using System.Web.UI.WebControls;
using System.Web.UI;
using System.Data;
using System.Collections;
using System;
namespace ASPresentation.Controls
{
[ToolboxData("<cc:PagedRepeater runat=server></cc:PagedRepeater>")]
public class PagedRepeater : Repeater
{
public int PageSize { get; set; }
public int CurrentPageIndex
{
get
{
return Convert.ToInt16(Page.Session["ProjectIndex"]);
}
set
{
Page.Session.Add("ProjectIndex", value);
}
}
public PagedDataSource pagedData = new PagedDataSource();
LinkButton NextBtn = new LinkButton();
LinkButton PrevBtn = new LinkButton();
public bool IsLastPage
{
get
{
return pagedData.IsLastPage;
}
}
public bool IsFirstPage
{
get
{
return pagedData.IsFirstPage;
}
}
public override object DataSource
{
get
{
return base.DataSource;
}
set
{
pagedData.DataSource = (IEnumerable)value;
}
}
protected void NextButtonClick(object sender, EventArgs e)
{
if (!IsLastPage)
{
CurrentPageIndex++;
}
}
protected void PrevButtonClick(object sender, EventArgs e)
{
if (!IsFirstPage)
{
CurrentPageIndex--;
}
}
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
NextBtn.Text = "Next";
PrevBtn.Text = "Prev";
NextBtn.Click += new EventHandler(NextButtonClick);
PrevBtn.Click += new EventHandler(PrevButtonClick);
}
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
base.Controls.Add(PrevBtn);
base.Controls.Add(NextBtn);
}
protected override void Render(HtmlTextWriter writer)
{
base.Render(writer);
}
public override void DataBind()
{
pagedData.AllowPaging = true;
pagedData.PageSize = PageSize;
pagedData.CurrentPageIndex = CurrentPageIndex;
base.DataSource = pagedData;
base.DataBind();

I have a div inside a user control that is displayed by the user after some event. I want to hide this div when user clicks anywhere elese on the page but not on the div (or not on any element that is inside the div).
If it wasn't a user control I could use body's clieck event to check the target, but because this is usercontrol that is hosted by other page I can't just "play" with it's elements. How can I achieve that without using body of the hosting page?
I'm using a FormView with a dynamically loaded item template. Inside the template (an ascx file loaded through Page.LoadTemplate(...) ) there is a button and I need to invoke the click event on that button.
View 1 RepliesDear friends, i'm working on user controls and events inside user control doesn't work for me.. my development process stuck due to this.
User control has a gridview which has rowcommands.
I need to insert code inside the SelectedIndexChanged event but it wont show up in my IDE :(

If I add another DropDownList outside my FormView it WILL display the events.
I have got an issue after updation in UpdatePanel. The issue is the jquery events are not working/firing after the updation in UpdatePanel. At first time, the jquery events work, but not after the updation in UpdatePanel. If I remove the UpdatePanel, the problem is solved. But I have to use the UpdatePanel.
View 1 Repliesm new to .NET. I'm trying to create a button dynamically with event by original button. The original button's click event response creates a button. The new button has a click event attached with a test message.What I have to do is onclick change background color of dynamically created button and grab id value to delete when button delete is clicked. Unfortunately, when I click the dynamically attached button,
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>

I've been reading up on the problems with dynamically created controls and how they have been solved. The posts I have come across are creating the controls in a panel or some other open place. I can't seem to get my checkbox to fire the event from inside a gridview. below is the code behind from inside the GridView PreRender event.
[Code]....
..And the Checked Event..
[Code]....
So after all this, nothing happens. I get the postback flash but my command inside the checked event doesn't fire.I tried putting the dynamic creation of the checkbox in Page Load with no effect.. I think because I can't place the checkbox inside the GridView under page load.
I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.
I have a set of CalendarExtenders. When I include my javascript file, the onclick event which pops up the calendar no longer displays. My javascript file adds onchange events to those text boxes.
