Raise ItemDataBound Event From Repeater Within User Control To Page?
May 20, 2010I have a user control that contains a repeater. We have added some paging and sorting into the user control and it all works well.
What I need now is a nice way to catch the OnItemDataBound event of the inner repeater and then bubble it up to be accessible directly from the user control from within the page.
We have tried catching it and then declaring it in the user control but it just won't work.
User Control To Raise An Event That Is Handled By Another User Control?
Jan 19, 2011Is there any way for one user control to raise an event that is handled by another user control without going through the page? I am using Umbraco and do not have access to the page object.
--Edit--
Umbraco has the idea of Macro's (user controls) that it loads into pages. I can't access the page directly as this is part of the framework.
There is a publish subscribe (pubsub) pattern that I know would fit my needs well (2 user controls that need to talk to each other) but am unsure how to hook it up in ASP.Net without the page object.

Mar 30, 2010I have a user control that displays some database records when I first hit the page. When I click the submit button the page load event fires again, loading the user control again. Then the button click event fires inserting a new row in the database which is not shown on the page because the user control already did its stuff. If I could get the user control to do its stuff after the button click event I could then see the newly inserted row. I can do this by pulling the code out of the button click event and sticking it in the page load event. However, I think that would be bad code flow. How can I get the user control to do its stuff after the button click event has fired?

Web Forms :: Dynamically Loaded User Control Button Event Not Firing?
Mar 11, 2011I have a aspx page, default.aspx, with an user control in it. Inside the user control (UC 1) there is a DataGrid. When the DataGrid is loading data with ItemDataBound, I need to dynamically load another user control (UC 2) for each row in the DataGrid. UC 2 has a Button ( BTN )with an eventhandler associated with it in code behind.
User control loading is fine, and the Button, BTN, is there. However, when I click the Button, the eventhandler is not reached, not firing, even though the page does postback. I googled for this issues, and I know the dynamically loaded user controls need to be loaded every time the page is postback. In my case, it needs to be loaded each time the datagrid is doing ItemDataBound. I did it and even hook up the eventhandler with button click event each time when the user control is dynamically loaded. I set EnableViewState to true on the Page and controls.
The following is part of the code from UC 1, AcctPaymentDetail is UC 2 in the code.

And the following is UC 2 the is being loaded:

How To Raise Events To Page From Dynamically Loaded User Control
Feb 23, 2010I have user control that inherits a base control class and these user controls are loaded using the LoadControl method, I can't seem to figure out how to raise events from user controls to the page that are dynamically loaded this way. Here is the delegate and event in the base user control class.
public delegate void SomeChangeEventHandler(object sender
, SomeChangeEventArgs e);
public event SomeChangeEventHandler SomeChangeEvent;
public virtual void OnSomeChanged(SomeChangeEventArgs e)
{
if (SomeChangeEvent != null)
{
SomeChangeEvent(this, e);
}

Web Forms :: User Control Command Button Event Doesn't Fire The First Time
Jan 19, 2011I am fairly new to the asp.net and experimenting with it to learn the page life cycle. Here is a problem that I have been unable to resolve for past few days.I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow. First user control is loaded on application start up. It has a "continue" button. Continue button click loads the Second user control that has two buttons - "Back" and "Submit". Obviously the "Back" button should load the first user control again and Submit button should submit the form data.
View 3 RepliesC# - Button Event In Web User Control?
Oct 21, 2010I have a problem with button event in web user control
First i have an aspx like this:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AddTest.aspx.cs" Inherits="AddTest" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script src="js/jquery-1.4.2.min.js" type="text/javascript"></script>
</head>
<body>
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div id="divContent" runat="server">
</div>
</form>
</body>
</html>
As you see i have a ScriptManager to do with ASP.NET AJAX, a div with ID divContent to load controls, then in code behind:
protected void Page_Load(object sender, EventArgs e)
{
divContent.Controls.Add(LoadControl("~/thitai/addtest.ascx"));
}
I add addtest.ascx to divContent as you see, and this is the code of addtest.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="addtest.ascx.cs" Inherits="thitai.addtest" %>
<asp:UpdatePanel ID="updatePanel" runat="server" ClientIDMode="Static">
<ContentTemplate>
<input type="button" value="Load text" onclick="updPanel('text');return false;" />
<input type="button" value="Load image" onclick="updPanel('image');return false;" />
<asp:HiddenField ID="hftype" runat="server" ClientIDMode="Static" />
<div>
<asp:PlaceHolder ID="plhControl" runat="server"></asp:PlaceHolder>
</div>
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
<script type="text/javascript">
function updPanel(type) {
$("#hftype").val(type);
__doPostBack("updatePanel", "");
}
</script>
Each time i click on Load text button, i change the value of hfType (hidden field) then do postback to server using UpdatePanel, then this is code behind
protected override void OnPreRender(EventArgs e)
{
string type = hftype.Value;
switch (type)
{
case "text":
plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx"));
break;
case "image":
plhControl.Controls.Add(LoadControl("~/thitai/test/image.ascx"));
break;
default:
plhControl.Controls.Add(LoadControl("~/thitai/test/text.ascx"));
break;
}
base.OnPreRender(e);
}
This is the code of text.ascx
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="text.ascx.cs" Inherits="thitai.test.text" %>
<%@ Register Assembly="Support" Namespace="Support.CustomEditor" TagPrefix="Editor" %>
<Editor:CustomEditor ID="edNoidung" runat="server" NoScript="True" Content=""
Height="500" ActiveMode="Design" NoUnicode="True" InitialCleanUp="False" />
<div>
<asp:Button ID="Button1" runat="server" Text="Show HTML"
onclick="Button1_Click" />
</div>
<div id="showHtml" runat="server"></div>
And code behind of text.ascx
protected void Button1_Click(object sender, EventArgs e)
{
showHtml.InnerHtml = edNoidung.Content;
}
The problem is: when i click to button1, the page do a postback using AJAX but event Button1_Click DOES NOT FIRE!

I have a hosting page (.aspx). Then I have two user controls (.ascx). The page has a place holder control in which it loads the user controls one at a time based on the application flow.

The problem is that the command button event handler that I have on the second user control is not firing the first time. (I have one event handler for both buttons). The load event of the user control fires but then it ignores the button click. If I click it again, then it fires. I re-load the controls on the page in every page_load. Here is some relevent code:

The page_Load fires every time but "CommandBtn_Click" doesn't fire after the first click. I have to do it click it again. It doesn't matter which order I click the buttons.

Child code:

If i use the child control directy (ie without the parent the control) the click event is raised and handled nicely. But when i use the parent control, the debugger wont even hit a breakpoint inside UpdateButton_Click().
Javascript - Unable To Bind Event With Link Button On User Control
Nov 3, 2010There are two user controls, which are built dynamically.
In the first control, I am adding a link button, and trying to attach a click event on the same. But the event is not fired.
Actually the main goal is, when the link is clicked, based on which one is clicked, I need to show second control (the values on the new controls are based on the first controls link button that is clicked).
If I use javascript, I will need to use ActiveX or is there any other way to instantiate the second control using javascript

Web Forms :: Load A User Control On Link Click Event Of A Link Button During Postback Of Aspx Page?
Mar 2, 2011Here is my requirement -
1. I need to load a user control on link click event of a link button during postback of aspx page.
2. On button click event of a save button on that aspx page, I need to read the selected values from that user control on further postback.
If I write the loadcontrol code in link_click event, the control is not recognized at all in the button_click event. When I shift it to page_init and execute only during not postback, the user control loads with default values.

I have to pass the authorID from the user control to the parent page.

Web Forms :: Firing Click Event On A User-control That Is Created From Another Event?
Mar 1, 2011I have a gridview called gvResults. In the gvResults_RowEditing event I add a row below the one selected. In that new row, which spans all columns, I insert a user-control. There are two buttons and some textboxes in the user control.
My problem is that when I click one of the user-control buttons it never gets to the button event handler, I think because the user control is not recreated on the page postback. How can I have the user-control events fire before the parent page events fire?
I tried using an update panel, but I still get the parent posting back before the user-control events.
