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'
I am a little confused what approach I should make as my standard designing web pages. I have been reading about relative and absolute positioning. Articles I have come accross seems to favour both. So from the experts I would like to know what standard I should adopt. Is there a combination that is good, example have panels be absolute and controls within be relative. I find it hard to work with relative positioning especially when you have to insert new control between already existing controls. Maybe I am doing things wrong?
I'm making a website in Visual Studio 2005 in VB.NET and I have a Label that needs to be visible if a GridView, populated from a SqlDataSource, has no rows.
I added message boxes to each event that the GridView has to see which was the last to run before it was displayed. I found that GridView1_Unload is the last event to run.
I added into this event the following code
Code: If CInt(GridView1.Rows.Count) > 0 Then lblNoTimeSheets.Visible = False Else lblNoTimeSheets.Visible = True End If After doing this the label doesn't hide when the GridView doesn't have any rows.
I even added in message boxes to see whether it actually go to the Visible = False line and it does.
i want to know what to do after desining a page with photoshop and fireworks to make an asp master page using visual studiosimply i have an html page i want to make a master page from it
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?
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?
I'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.
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.
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€
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.
I have problem with my web form login  <div> <h1>Konsole - Login</h1> UserID : <asp:TextBox ID="tb_uid" runat="server" autoComplete="off"></asp:TextBox> Password :<asp:TextBox ID="tb_pass" runat="server" autoComplete="off"></asp:TextBox> <asp:Button ID="btn_submit" runat="server" Text="SignIN" /> <br />
[code]...
design code is above and following error occured "WebForms UnobtrusiveValidationMode requires a ScriptResourceMapping for 'jquery'. Please add a ScriptResourceMapping named jquery(case-sensitive)."
I have the user control and web page. When I place user control in the web page and in design time, it cannot view and error is "System.Web.UI.UserControl does not have a public property named 'ContentTemplate". It seems not related of error message.
In 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") %>'
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?
None 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?
