I installed Rad Controls. Using that controls, I designed my application pages. At design time, the design is not visible. It shows the following error:
RadTabStrip1Failed to create designer 'Telerik.Web.UI.RadTabStrip, Telerik.Web.UI, Version=2010.1.415.35, Culture=neutral, PublicKeyToken=121fae78165ba3d4'
This is my first experience with themes.I've created a skin file for a textbox and the defined theme is only visible at runtime.Is this the way theme works or I am missing something?
View 1 RepliesI am learning asp.net using Visual web developer 2008 express.
I have an image control with the html code below
<div class="Header">
<asp:Image ID="image1" runat="server"
ImageUrl="D:/Master/test.jpg" Width="500" Height="300"
AlternateText="UNRA Fort Portal Intranet"/>
</div>
In design view, the image shows but when i run the app, the image is not shown. Only the alternate text is displayed.
 The css code code as below.
.Header
{
top:10px;
left:20px;
position:absolute;
width:800px;
background-image:URL(D:/Master/test.jpg);
background-repeat:repeat-x;
}
I've just started working on some test asp.net webforms projects and am having a problem with VS2010. It is not displaying any controls at design-time. For every control I'm getting message -
Error Creating Control - xxxxx
Object reference not set to an instance of an object
It is doing it on new web.application and Tailspin Spyworks demo app. If I switch a new web.app from asp.net4 to asp.net3.5, all the controls display properly.
I've tried removing and re-installing VS2010 and had no changes.
It acts like something didn't get installed.
Am I right in assuming that only after controls on Master page are merged into the control tree for the Page, can controls ( both those in Master page and in a content Page ) be initialized with their declarative values ( values set during design time)? b) If my above assumption is correct, then these controls cannot be initialized with their design-time values during Page.PreInit, since during Page.PreInit event stage we're still able to dynamically set a Master page?! So if that is the case, when are controls initialized with their declarative values? During Init event orâ€
View 1 RepliesWhen I try to look at my masterpage/form in design view it's only partially visible. It's shifted so far to the left that i can only see the right half of it. I don't understand why. I'm using negative margins to center the form at runtime, which is working great. It appears to be shifted to left about half of it's width, which would equal the negative margin.
CSS for negative margin:

Is this a deficiency with the rendering in Design view? Is it a discrepancy between the way a browser would interpret the styles and the was the Design view interprets them?
I am designing an ASP.NET v3.5 custom control based on CompositeControl.
However, I do NOT want to create my child controls via code, but rather as
embedded HTML tag elements within the CompositeControl in the ASPX page, such as:
[code]....
At run time, MyControl.Controls contains the two labels as expected.
At design time, MyControl.Controls is empty.
I need this information at design time for various reasons.
What am I doing wrong?
I'm developing a custom server control and want it to end with /> rather than with </cc1:CustCtrl>. I've tried changing the ToolboxData but it didn't really do it (I can see it initially appears like that but instantly changes to the standard <cc1:CustCtrl blah blah></cc1:CustCtrl>. When i drag a button from the toolbox to the forms markup it uses the <asp:Button blah blah /> markup, how can I emulate this?
View 3 Repliescan't connect to sql 2005 express sp1 and vs is also sp1. 2) Which my guess is because of the database connection not being able... design view is not able to pull in the application for design, it's as if there is no theme and css just white background and black print.
View 1 RepliesNone of my user controls display on a web form at design time. At runtime they work fine and at design time to design the user controls themselve is fine.
Is there a setting that is telling the controls not to render at design time?
i create a custom control which can hold some templates, such as Header, Body Footer, etc.
[Code]....
i tried to use smarttags to allow the user to edit each of the templates, which worked pretty well. what i could not get working was to add a template if it has not been in the control. eg. add a header-template to the control above. i tried using the RootDesigner.AddControlToDocument() function of my controldesigner. but this function gives me an error, telling me the control i'm going to add the template (i used a new HtmlGenericControl("HeaderTemplate") as new Control) to is not valid. (i can't give the exact error message, cause i use a german version of visual studio 2008) i've been searching the web for nearly half a day now, but i did'nt find a working solution for my problem.
I have created an advanced label control using web user control to cater some advanced options needed for my application. The control is working fine but there is one hitch bothering me. In normal label control when we change text or color, we can see effects during design time also but this is not functional with web user control. I mean when i change TEXT property of my label inside user control, the effect is visible on runtime not design time.
Is there any way to see effect of property changes during design time??
I have a custom Panel with attribute Designer(typeof(xxxMainPanelEditor), typeof(System.Web.UI.Design.WebControls.PanelContainerDesigner)). The child controls of this custom Panel Control at design time can see all the exposed properties that I want to share from the Parent (no problem here).
However, if I place controls on an UpdatePanel, these child controls cannot see the parent container but instead, it immediately sees the form/page or DesignerHost. The problem is the same even if I put Panel on the UpdatePanel and vise versa.
Is there a way to manage controls inside an update panel? For me, this behavior is like saying that UpdatePanel is not container based during design time?
a) Assuming a page has a master page associated with it, then all controls (those declared in master page and those declared in content page) created during design time are assigned declarative values only during an Init event? I'm assuming this since to my understanding controls need first to be put into the control tree before they can be assigned their declarative values? And when page has a master page associated with it, then aren't page's controls put into the control tree only during the Pre_Init or perhaps even during the Init event? Then if that is the case, then isn't the earliest that these controls can be assigned their declarative values during Init event?
b) Assuming our page is associated with Master page and also uses a theme --> skin files are also applied during an Init event, so I assume that during an Init event Asp.Net first initializes controls to their declarative values and only then applies skin rules to them?
I have use composite custome control its contain button and textbox and gridveiw
but design time gridview is not display .
I'm about to design my Web service API, most of the functions of my API is basically very simular to my web application. Now the question is, should I create 1 single method and reuse them for both the web application and the web service api? (This seems to be the logical solution, however its very complicated; it's much easier to duplicate the method used by the web application, and keep both separate, ie one method for the web application and one method for the web service.)
1) REUSE: one main method and reuse them for both web application and web service application (I like this but it's complicated)
WebAppMethodX --uses-->
COMMONFUNCTIONMETHOD_X
APIMethodX ---uses---->
COMMONFUNCTIONMETHOD_X
ie Commonfunctionmethod_x contains reusable set of common features
PRO: less code, less maintenance, less bugs.
CON: very complicated
2) DUPLICATE: two methods, one method for the web application and one method for the web service.
WebAppMethodX
APIMethodX
PRO: simple
CON: duplication = more code, more maintenance, more bugs!
i need to create div on run time in such a manner as it create table at run time,(table is also in another div) .
all my rows in table like this (for example)
Code:

let me tell u one more thing above div is sub div of many other divs .how i will access how to add runtime to design time div?
Im making a small user control, i was wondering if it was possible to make some sort of comment, that is only visible design time. For example i would like to write in the top of my control that it requires a querystring parameter named userid. This way other developers can quickly see the requirements?
View 2 RepliesI'm developing a set of custom controls, one of them are the "parent", any others must be added inside an ITemplate property of this parent. But in the page, at design time, I can see, by intellisense, the other controls at page level, and I can theorically add them everywhere. I want to emulate the behaviour of the asp:Table and the asp:TableRow, you can't directly add an asp.
View 2 RepliesI render some markup dynamically in a Web User Control, can I get that out in design mode, and not only runtime?
public override void RenderControl(HtmlTextWriter writer)
{
if (this.DesignMode)
writer.Write("<p>In design mode</p>");
else
base.RenderControl(writer);
}
... nothing happens when I check the design view of the control. Not if I remove the if (this.DesignMode)-condition either.
I'm using VS 2008 with the AjaxControlToolkit and at design time I am dragging some regex validators on the page.
Prior to yesterday, when I did this, the design time control allowed me to click a little arrow in the upper right hand of the control and add an extender.
Well, now that ability to add an extender at design time is gone, and I don't know what happened.

View 5 RepliesIn my company we use a control that renders the <link rel="stylesheet"> tags dynamically at runtime (equivalent of scriptmanager who renders <script> tags dynamically). this control is very good, cause it select the appropriate css stylesheets depending on some criterias. The problem is that on design time for Visual Studio there is no designated CSS stylecheet since there is no <link rel="stylesheet"> tags on the page.
If I put <link rel="stylesheet"> tags on the aspx page (to indicate a design time stylesheet) this tag will be rendered to client and it causes conflicts with tags rendered by the control !
I am trying to find the best way to concatenate two strings and set the result to the text property of a label during design time.Here is what is not working:
I have Text="<%$Resources:labels, btnLinkNoText%>" and Text='<%# Bind("ProductID") %>'
I want Text="<%$Resources:labels, btnLinkNoText%>" + Text='<%# Bind("ProductID") %>'
