I want to render a user control in pagemethod and return the html back to client. But its getting annoying, I tried like many ways but nothing found working. The problem is that, the usercontrol require both HtmlHead and ScriptManager.
I tried this but it doesn't work(raise error : ScriptManger require in page) because ScriptManager must be inside HtmlForm but Page.Form always null.

I have a user control having a pagemethod. I want to call this pagemethod from my page using jquery's ajax() method?
View 5 RepliesI 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.
I am using web user control and making it visible false initially (page load) and on the selection of checkbox i am making it visible true. user control html is missing when i load it on checkbox selection. is there any when that i rebind the complete form again on checkbox selection so that user control html should be rendered.
i am really struggling to solve this issue since last two days.
I have a scenario where, the content is:
[code]....
The entire div code is rendered and is sent at a mail using the code:
[Code]....
This works fine except that the User Control does not get rendered.
so that the User Control content is also rendered ?
Render User Control with Events in html
View 6 Repliesi'm just new in ASP.Net.
I want to render a Web User Control (has many server controls inside of it) as a HTML string, is there anyway to do it?
I 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.
I'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?

I have come across a requirement to dynamically show or hide asp.net web controls , html server controls. I want to do this through a configuration XML (as it would be easier to config). So each page /aspx will have a configuration xml.
Would it be possible to create a control (may be a custom control , to which i can attach the xml file). The control (lets says - call it sequencer) should decide which control should be ordered in which order and if the control has to be shown or not. Ideally this sequencer control should use the page events and take decision on rendering the child controls.
Some thing like this
aspx -
<Sequencer XmlPath=".." Id="S1" Runat="server">
<Textbox id="t1" runat="server" />
<Textbox id="t2" runat="server" />
<Textbox id="t3" runat="server" />
</Sequencer>
This is hiw xml config may look like -
<Sequencer Id="S1">
<control id="t1" sequence="2" show="true" />
<control id="t2" sequence="1" show="true" />
<control id="t3" sequence="3" show="false" />
</Sequencer>
So in this case t2 should be rendered first then t1. The control id in the xml and the aspx has to be same.
t3 should not be rendered at all on the screen.
Which page load event should I use.
how I can create this kind of a custom control that does the above for me.
Iam Creating a Hyperlink control in code behind user this way
string literalControl = "<asp:HyperLink ID="HyperLink1" onclick="fnClearField('asdf')" ForeColor="Red" Font-Underline=true CssClass="Row_Over_Ar_Ex" runat="server" >Clear</asp:HyperLink>";
cell.add( new literalcontrol(literalControl ))
but the control not showing all the style attributs, is this way the style attributes will not show?
do i have to create the server control using new hyperlink and then add all the attributes?
I've build a custom WebControl, which has the following structure:
<gws:ModalBox ID="ModalBox1" HeaderText="Title" runat="server">
<Contents>
<asp:Label ID="KeywordLabel" AssociatedControlID="KeywordTextBox" runat="server">Keyword: </asp:Label><br />
<asp:TextBox ID="KeywordTextBox" Text="" runat="server" />
[Code]....
However it seems to render properly, it doesn't work anymore if I add some asp.net labels and input controls inside the property (see above asp.net code). I'll get the HttpException:
Unable to find control with id 'KeywordTextBox' that is associated with the Label 'KeywordLabel'.
Somewhat understandable, because the label appears before the textbox in the controlcollection. However, with default asp.net controls it does work, so why doesn't this work? What am I doing wrong? Is it even possible to have two control collections in one control? Should I render it differently?
I don't think I understand fully how ASP.NET does inheritance of controls.I have a user control, ucBase, which has an asp.net label in the ascx file. Code behind references the label and it works fine during run time if the control is not a parent for another user parent.
If I have another user control, ucChild, inheriting from ucBase, the label in ucBase's code is always null. ucChild has no controls in its ascx fileThe server controls (like the label) needs to be declared in the ascx file and not created programmatically.What needs to be done for ucBase to see its own controls when it's a parent user control?
We have an application where the controls are dynamically added to the form based on the logged in user,
This user controls related data is stored in the database. There is lot of logic in the code behind in the asp.net webforms which is so messy to maintain it, we are planning to re-write it using the MVC framework.
I would say there would be rougly 50 different forms based on the user logged in, is it good idea to create so many views and redirect to the appropriate view based on the logged in user, in some of the forms there might be minor difference like the order of the Control might change.

I've got a web site that has a master page and that master page (mpMaster that has a user control ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page
and on this page I have another user control (ucPageControl), I need to find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all?

PageMethod which supposed to be called/executed when "onChange' of dropdownlist is triggered is Not being executed. I have 3 dropdownlist being created at runtime/dynamically inside a compositecontrol class and loaded (.dll) in a page at runtime. I have added a scriptmanager in the master page and set EnablePageMethods to true, tried placing the webmethod function outside of the compositecontrol and in the page, still webmethod is not being called... Anyone has idea or solution to this problem of mine? Or another approach to retain the selected value of the dropdownlist inside this compositecontrol (.dll) that is being loaded in a page at runtime?

I want to know that how to render partial view based on where the user navigates. I mean to say if user navigates to Home/index it will load different partial view and if user navigates to Home/contact it will load different partial view on the _layout page.
View 1 RepliesFor example what if I am trying to hide a custom navigation control what can I place in another webcontrol to conditionally hide the label something like this
<mycontrol:hidethis id=mycontrol1 runat="server">

I need to render a particular partial view multiple times inside a view whenever user perofrm an action like button click event.How we do it in mvc?
All I would like to be able to do is include one user control within another! Is this possible? I have spent the last hour searching the internet and it seems that I can't find a single thing.
In classic ASP it would be something like:
<!--#include file="EditProject.ascx"-->
I tried this but no luck!

I have a web page rendering two pie charts using the ASP.NET 3.5 chart controls. On my dev server (IIS 5.1) the charts load well. On the QA server, the charts load pretty slowly and sometimes one or both of them doesn't even load. I am loading the charts using the codebehind tag. Is there anything else that could be done to make these charts run faster? Note: I was previously using dotNETCHARTING and never had any issues with it. Nothing else has changed except for the charting engine.
