Oct 16, 2010How to wire up HTML server controls events?

Web Forms :: Render A User Control As An Image?
Aug 2, 2010I have a complicated user control on a form that's laid out they way the business unit wants it. What they would like is to be able to export this content to excel and/or PDF as an image. Basically I need to be able to render the user control as a static image.
Is there any simple way to do this or is it even possible? Since the user control is HTML, it's not really rendered at all at the server level as it's just HTML, so I would assume that I might need to interface with IE library.

Render Control To Html Produces A Different String?
Jul 7, 2010I am trying to render a hyperlink to html. ( etc)
When the page loads it works fine. (and lots 10 links) on the update panel it hits the same function and tries to get another 10 links. I set the navigationURL to something like
"../Folder/Mypage.aspx?498592ghjgfosdfgo"
It is set identically both times(load and updatepanel postback) but when i try to render it to html the second time (on the update panel) it adds "../" to the front so i end up with
"../../Folder/Mypage.aspx?498592ghjgfosdfgo"
The function where it changes here
Public Shared Function RenderControl(ByVal c As Control) As String
Dim sw As New IO.StringWriter
Dim htmlw As New HtmlTextWriter(sw)
c.RenderControl(htmlw)
Return sw.ToString
End Function
c is the hyperlink which has the propertry navigationurl (this never gets changed) but the sw which ends up looking like this on load
<a id="lnkView" href="../Folder/mypage.aspx?AnTfh0ZsFP9NCxiBpM+Zd11cI+AUOF93HZQtumPgzMKky0PejGrda9I6kCFn070dOsIfq0M2AgI=">View</a>}
and this on panel update
<a id="lnkView" href="../../Folder/mypage.aspx?AnTfh0ZsFP9NCxiBpM+Zd11cI+AUOF93HZQtumPgzMKky0PejGrda9I6kCFn070dOsIfq0M2AgI=">View</a>}

Jan 14, 2011I've these codes in my DATABASE in other words it's HTML. I tried these stuff:

I tried in C# code behind:
div1.InnerText = contents;

All these HTML's are in DABASE.Column e.g. column "Contents"

I've put (spaces between & and gt above code otherwise it was not showing in stackoverflow.) The HTML sysntaxs are correct because it's created by an HTMLEDITOR.
Web Forms :: How To Use Delegate In User Control To Trigger Events
Mar 2, 2011I have got a query regarding the usage of delegate in usercontrols. The scenario is I have got a user control which acts as a footer
on all the pages, It has the following place holders : Email, Print, Logout.
What I want to acheive here is when the customer logged in he/she has certain feauture's on the website for instance his/her personal diary,
dieting charts, birthday calender etc. I have figured out a way to create pdf's of each summary , what I am looking for is how to use the usercontrol
for instance when the customer clicks on the email place holder on certain page which is in the footer usercontrol, the following place holder should send
an email with the pdf file of that particular page attached to the customer. I came to know that delegate is the best way of doing it, but I cant find any specific tutorial on it.

Forms Data Controls :: Handling Events From A User Control Inside A GridView?
Jun 4, 2010I 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.
C# - How To Render User Control Children At A Specific Location
Jan 7, 2010I have a very simplistic user control that looks like this:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="wfWindow.ascx.cs" Inherits="webfanatix.co.za.wfWindow" %>
<div>Just a test...[x]</div>
with this code behind:
[ParseChildren(false)]
[PersistChildren(true)]
public partial class wfWindow : System.Web.UI.UserControl
{
protected override void Render(HtmlTextWriter writer)
{
RenderChildren(writer);
}
}
And the usage thereof looks like this:
<wf:wfWindow runat="server">This content should go where [x] is.</wf:wfWindow>
I'm no ASP.NET pro, so how do I get the content to render exactly where the [x] appears in my user control?
RenderChildren is rendering my content, but it is only appended to the end of the UserControl output. I need it to go and sit right where [x] marks the spot.

Web Form Render Engine Outputs A Control Tree / Looking For Info On Render Logic.
Feb 12, 2011I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).
I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?
C# - Multiple Page_Load Events For A User Control When Using URL Routing?
Jan 6, 2011've recently set up an ASP.net site (not using MVC.net) to use URL Routing (more on the code below) - when using user controls on the site (i.e I've created a "menu" user control to hold menu information) the page_load event for that control will fire twice when URLs have more than one variable passed over.
i.e.
pageName/VAR1 : will only fire the page_load event once.
while
pageName/VAR1/VAR2 : will fire the page_load event twice.
*Multiple extra VARs added on the end will still only fire the page_load event twice*.
Below are the code snippits from the files, the first is the MapPageRoute, located in the Global.asax :
[code]....
Note, that when I'm just hitting the page and it uses the default values for items, the reloads do not happen.
Javascript - Adding Click Events To User Control?
Aug 28, 2010I have a user control in an asp.net web application. The control outputs an html list that is customized based on the currently logged in user. The list items are generated from a database look up and the user control is formatted to appear as a drop down list in the page.
The control itself is simple and looks like this:
<%@ Control Language="VB" AutoEventWireup="false" CodeFile="item-lector.ascx.vb" Inherits="includes_usercontrols_item_selector" %>
<!--Item Selector-->
<div id="item-selector">
<%=Me.Output%>
</div>
The code behind file dynamically fills the control's "output" property so the final markup appears as follows:
<div id="item-selector">
<h1>Item 1 - Item 1</h1>
<a href="#" class="changeItem itemArrow">Change item</a>
<ul id="changeItemMenu" class="dropDownMenu">
<li><a href="#">Item 1</a></li>
<li><a href="#">Item 2</a></li>
<li><a href="#">Item 3</a></li>
<li><a href="#">Item 4</a></li>
<li><a href="#">Item 5</a></li>
<li><a href="#">Item 6</a></li>
<li><a href="#">Item 7</a></li>
<li><a href="#">Item 8</a></li>
<li><a href="#">Item 9</a></li>
<li><a href="#">Item 10</a></li>
</ul>
</div>
The ID and class properties are all necessary for formatting and other scripting. The control is meant to be used as a selector and the rest of the page should react to which item the user selects.
What I am trying to do is add click events to the list items. When the user clicks on one of the items in the list, I want to capture which item the user selects in the list (does this require a postback?) and do something with it in the code behind (< this is key).
I am more of a middle tier and db tier developer and UI development is not my strength so please consider me a newbie in that regard. I am not sure how to proceed or what to inject into the output string to enable this.
How To Handle Dynamic User Control Events In Aspx Page
Oct 28, 2010I have an aspx webpage in which an user control is added dynamically as follows:
UserControl testUsrControl = LoadControl("TestUsrControl") as UserControl;

But this line is giving error at **testUsrControl.Drpdatafield_SelectIndexChanged **. The error is "Drpdatafield_SelectIndexChanged" doesn't exist in UserControl.How can get the testUsrControl's events inside aspx page dynamically.
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);
}

AJAX :: Button Is Pressed On The User Control, The Events Are Fired But There Are No Changes In The Page
Aug 3, 2010I have an update panel on the parent page into which I load and remove a set of user controls.
Now, when a button is pressed on the user control, the events are fired but there are no changes in the page. For example:
Main Page
<updatePanelMain>
<childcontrol1>
<childcontrol2>
etc
ChildControl.ascx
<update panel 1>
<panel1/>
<panel2/>
<btn1/>
etc
So, if I want to hide panel 1 when btn1 is clicked etc, I simple use code such as panel1.visible = false.
All this gets executed but nothing happens to the page.
<asp:UpdatePanel ChildrenAsTriggers="false" UpdateMode="Conditional" ID="updatePanel"
runat="server" EnableViewState="true">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" />
</Triggers>
<ContentTemplate>
However, when I use placeholders instead of update panels in the child controls, I dont face any such problems.
<asp:PlaceHolder ID="placeholderTypeOfInvestor" runat="server">
