Visual Studio Designer does not display custom control with embedded image

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :ASP.Net


I am developing a custom control which includes an embeded image to display in the design mode of the control. The Visual Studio designer does not display the image of the custom control. Here is the html generated by the overloaded GetDesignTimeHtml() function:


<div style='height:30px;width:215px;border:5;'><input type="text" value="[DropDownListMultiColumn1]" style="height:25px;width:175px;margin:0;padding:0;border-spacing:0;" /><img  src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAA0AAAASCAIAAAAPCcNlAAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAgY0hSTQAAeiYAAICEAAD6AAAAgOgAAHUwAADqYAAAOpgAABdwnLpRPAAAAEpJREFUKFNjPHDgAAMh4ODgwABU9x8vaGhoAJkDUQckcYEhqA4tfCA+w+4PuFK493H6FxJYhNWhBeQQDD+sSQHhDyALPyCUPpHkAUdqnQngjlwtAAAAAElFTkSuQmCC" style="height:20px;width:15px;margin:0;padding:0;border-spacing:0;" /></div>


This markup displays as expected within an html form. However, in Visual Studio, it shows a red x where the image should be displayed.

How to display breakpoint and debug visual cues with custom activity designer based on WorkflowViewE

Hi,   I am developing custom activity designers based on "WorkflowViewElement" instead of "ActivityDesigner" in my xaml. It allows me to have greater control of the look and feel of the designer. However I noticed that with this approach, the breakpoint visual cue (Dark red solid circle that appears on the left side of the designer when you set breakpoint on the designer) is not visible. It works fine when you write your designed based on "ActivityDesigner". The same behavior happens to the debug visual cue when you debugging the WF. It appears as bright yellow rectangle surrounding the activity designer if you are based on "ActivityDesigner", but it is not available when your designer is based on"WorkflowViewElement". Any help is highly appreciated. Li

How to implement Design-Time drag & drop from Custom Visual Studio Tool Window to WPF Designer

Hi, Could someone tell me if it is possible to intercept a design time drop event coming from a custom Visual Studio tool window onto the cider design surface? I am hoping to use the same API's as those used by the Visual Studio 2010 'Data Sources' tool window, which provides drag & drop data-binding between classes and WPF/Silverlight controls. My requirement is to pass a DataObject (used with the WPF DragDrop API) from my custom Visual Studio WPF tool window treeview to my custom WPF control at design time, read the data and do some binding/XAML manipulation of my own. The drag aspect is simple enough but I can't work out how to accept a drop event from anything other than the toolbox. At the moment, when I drag my treenode over the design surface it shows the 'cannot drop here' cursor. If someone could give me some insight into how the 'Data Sources' tool window allows dragging of treenodes to controls I would really appreciate it. It is obviously possible but which API's are used and are they public? Thanks in advance, Paul  

Visual Studio closes itself by opening aspx-Page designer after Windows Update


Hey Guys,

I've a problem with my Visual Studio.

On the 13th of August 2010 i installed a Windows update on my vista sp2 pc. For this date my Visual Studio 2008 sp 1 always has closed itself by opening an aspx-page in designer view. There is no error message just closing the window. I restored a backup of my windows from the time before updating it and it helped, i could open aspx pages in the design view till the update has been installed again automatically after rebooting the pc. I can't disable windows updates, cause it's my pc at work and safety is very important. I hope you could help me out of this disaster.

Visual Studio .NET: Custom Add-Ins Help You Maximize the Productivity of Visual Studio .NET


Regardless of how great an integrated development environment (IDE) is, there will always be features that developers wish had been included. For that reason, the Visual Studio .NET IDE provides an extensive add-in facility that allows you to add nearly unlimited numbers of features and functionalities written in Visual Basic, C, C++, C#, or any .NET-compliant language. This article explains how add-ins work in Visual Studio .NET. It then shows how to add custom text editing by creating an add-in with two editing functions, a simple text insert of the current date, and a more complex function to reformat paragraphs of text. Finally, you'll learn how to add a page to the Options dialog.

Visual Studio designer event problem


Hi there

I have a small issue that I'm sure others have experienced - but haven't yet found a solution / workaround for this.

When adding controls to Visual Studio in designer you normally get a event button (the yellow flash light) in the properties window.

But when you nest a button inside a placeholder (for example) you cannot mark the button from the designer - only the placeholder! When trying to go into "split-view" on the designer you'll be able to mark the button in the bottom of the designer - but only properties and not the event button appers in the properties window!

I know that you can go into codebehind and manually add the event but I thiink it is really tiresome to do so if I don't have to...

I had a small hope that VS2010 the issue would be gone but sadly it isn't...

Anyone ever found a solution for this one?

Kind regards Thomas

Where is the Visual Studio 2008 Web Control Library Template


Does a project exist for grouping user controls? Visual Studio 2005 had this template but it does not appear to exist in 2008.

We will be creating several User Controls and would like them grouped accordingly.


Thanks in advance for any responses.

WPF Designer (in VS 2008 and VS 2010) crashes with Visual Studio

Good day all. I have the following question: WPF designer in both VS 2008 and VS 2010 crashes with Visual Studio when I try to edit UI form. Moreover, it crashes even when I try to save .xaml.cs file. Meanwhile, Winforms and Dataset UI editors work as usual. Are there other people met this issue? And how could I fix up this problem? Deleting the .suo file, uninstalling silverlight, repairing visual studio, and further googling did not help me. Thanks in advance.

Visual Studio 2008 Failing to Add New Controls into *.designer.cs

I've encountered a situation with my current project where, when I add a new control, VS2008 is not adding it into the associated Designer file.  This is occurring with both a Web Page (ASPX) and a User Control (ASCX).At first I thought it was because I was going into the layout page and manually adding a control that way.  But then when I went back to dragging the controls right from the ToolBox the problem persisted.Why is this happening and how can I fix it?Robert

Visual Studio Extension: Save UML diagram as image

I am auditing one big legacy application. I use Visual Studio 2010 modeling projects to visualize the design of this legacy application. When I wanted to get my UML diagrams to image files so I can insert them to documents I found no option for it. As it turned out we have to write extension for modeling projects and deploy it as Visual Studio 2010 extension. Here is the installer and source package of my UML.SaveAsImage extension. UML.SaveAsImage.zip VS2010 solution | 48KB UML.SaveAsImage.Install.zip VSIX insaller | 4KB I still cannot believe that we need to write extensions to get our UML diagrams to image files but okay, it's done now and let's say - problem is solved. At least this one. In my work I used code example by Cameron Skinner. He has very good blog posting titled as Save a diagram to Image File. Here are steps how I wrote this extension. 1. Create new Layer Designer Command Extension project As a first thing you should create layer designer command extension project. If you don't have support for modeling projects you should take more powerful edition of Visual Studio 2010. Name it your project as you like and click OK. 2. Add functionality to Command class You can find Command class from your new project. This class is created by default. Here is the modified code from Cameron Ski
