.net - Hide A Property From Going Into The Form Designer File?
Dec 17, 2010
I am working in VB.NET 2010 Framework 2.0.
I don't want to allow some properties from going into form's designer file but the those properties will present on the form(property grid). The behavior of these properties will be same always.
I used the following code:
<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>
Public Property GradientBegin() As Color = Color.Red
But the problem I am facing is that -> on the property grid after changing the "GradientBegin" color to other than RED and compiling the program, it is replacing the new changed value to RED again. So I am not able to change the color actually.

I am working in VB.Net 2010 framework 2.0. Suppose i declares a property
[Code]....
In the form designer, the property "MyColor" will be seen the value as 150, 145, 145. I want to see this value as "NewColor" in form designer. This is the same like ControlDark, ActiveBorder etc. system colors. I want that instead of the color value, designer should show the variable name. The .Net framework also use the above implementation for System Colors and same i want to do.

I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?

When I open VB projects in Visual Studio 2005 and attempt to view a form view designer I have started getting "File Download - Security Warning" Message prompting a .tmp file in the location of my project. If I close all open designers and rebuild the project I am then able to open the designers OK.I saw a suggestion to 'restore file associations' in Visual Studio and tried this but with no success.

I'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?

I have an abstract user control(baseModule) that has a property that I plan on using a bitwise comparison on to determine what export types are supported by that module. In the designer of a module derived from baseModule, I am presented with a combobox with the ability to just select a single value (Html, Xml, etc.) I would like to be presented with a drop-down checked listbox so I could select which values I want.How can I accomplish this inside of VS2008? I've seen other properties support this.

Ive recently written a control called a ButtonRow in VB.NET that allows you to dynamically place buttons on it through a typed collection property. The property itself is tagged with the <DesignerSerializationVisibility(DesignerSerializationVisibility.Content)>. However it works really bad. First of all, whenever you add buttons to it and you delete the controlafterwards, the designer code file still have the buttons declared but without the aButtonRow to who's collection they would be added. Secondly, you cannot copy the controlfrom one form to another. It would just copy the ButtonRow object without the buttons

I have some related Properties in a class. Namely, One is a collection of objects and the other is an index to the one that the class instance is looking at. In the designer, I need for the collection to be set prior to the index. I tried to do this manually, but when the file is saved, the Designer goes back and writes over my change. So I need to know how to tell the designer in which order to set the properties.

I want to add a List(Of Book) property to my user control. I defined a Book class and BookCollectionEditor class for CollectionEditor. And also I defined a public property named BookList for my user control. For a custom control it works fine but for user control, the designer does not display my property. On markup I can add a Book item but on designer it gives error: "Type 'System.Web.UI.UserControl' does not have a public property named 'BookList'."Isn't is possible to define a list property for a user control?

I have written a Visual Studio 2008 addin that adds controls to a Form. I want some of those controls' Visible property set to False so they're hidden during runtime, so I do this:[code..]
This doesn't work. Not only is the control invisible in the designer window itself, but the Visible = False code doesn't even make it into [FormName].designer.vb. I have tried forcing Serialization on the Visible property like so, to no avail:[code...]

I have been making a control and have added a property for a list(of CustomClass). The custom class contains a string, an image and a list of another custom class which contains a string and an image. I have added this property to the designer by adding the browsable attributes and all appears to work correctly with this.
My problem comes when running the program. I can set all of the values within the property and I can go back to them and they are saved, however, as soon as I run the program, the values are wiped out as the property is set to Nothing.In order to allow my property to be edited and saved, I realize that I must initialize the list and have done so in the accessor method of the property (if the property's value is nothing).
I have modified the values in the designer and placed a breakpoint on all of the items which use the property and it's underlying field, as well as on the property's methods itself. The first breakpoint hit is of it being accessed and the value is always nothing.
I'm not sure where the values are supposed to be stored as I have checked the designer code where it would normally store types such as strings and I have checked the resources to see if they have been saved there (like an image would be). After running the code, the values in the designer are wiped out also.

I'm creating a UserControl that draws a simple radial gauge. I need it to be very customizable; the user should be able to customize everything such as the colors, fonts, sizes. So, I just made a property for every customizable detail. For example, I had ScaleFont, ScaleColor, ScaleStart, ScaleEnd, ScaleInnerRadius, ScaleOuterRadius, ScaleTickmarkFrequenty, etc.. etc.. etc...
Because there are so many properties about the same subject, I wanted to 'group' these properties into one "property". I've seen this done loads of times in third party controls, but I've never done it before myself.The idea is that the properties can be accessed like
Me.Gauge1.ScaleSettings.Start = 10
Me.Gauge1.ScaleSettings.End = 80
...
So far, I tried creating a class for each group, for example a clsScaleSettings class, containing properties like Font, Color, Start, End, InnerRadius, OuterRadius, TickmarkFrequenty, etc (corresponding to the same properties as above).
Then, for every 'group' or class, I create a Property. For example, I have the ScaleSettings property, which simply returns an instance of the clsScaleSettings class (I initialize the instance only once of course):
vb.net
Private _ScaleSettings As New clsScaleSettings
Public Property ScaleSettings() As clsScaleSettings
[code]....
Now, this works in the code editor. I can now use
Gauge1.ScaleSettings.Font = Me.Font
for example, and it sets the font correctly.But, I does not work in the designer, in the Property Grid. The whole reason I made the effort to move and rename nearly all properties (about 70!), and all references to those properties, to separate classes, was so that the user could design the gauge more easily using the Property Grid!Instead of having 15 settings related to the scale, scattered all over the Property Grid, he can now have one ScaleSettings property, which he can expand, and then he can edit the properties of that group easily.The ScaleSettings property is greyed out in the property grid... So I cannot expand it and view it's underlying properties.

I'm writing a custom control and I want to add a "MessageText" property of type String:
<Browsable(True),
DefaultValue(""),
Category("CustomControls"),
[code]....
The MessageText property is a multiline text, and the user must be able to set the text using the designer. The problem is that the designer doesn't allow to enter a newline directly for a string property.I want the same behaviour as the system TextBox's Text property, where you can click on the down arrow and write lines in the small text-editor that appears:How do I do that?

I have a Class A that inherits from a base class. In the class A i have build some methods/properties.What I want is that some methods/properties from the base class are not visible in the intellisense which makes it easier for a developer. Basically i want to hide all the methods/functions/etc.. which are no use.Is this possible whithout having to use the EditorBrowsableAttribute for every item?The best way would be to tell the class that it must hide all props/methods/functions/etc... and after that i can specify which MUST be visible.
'by default hide all props/functions/etc.... ????

I inherit from ListView. I want my control to have an AllowCheckBoxes property rather than a CheckBoxes property.
Listview.Checkboxes is not overridable.
Can I add attributes to Listview.Checkboxes? Maybe the following?
<Browsable(False), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>
If not, does the following make sense?
<Browsable(False), DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)>
Public Property Shadows CheckBoxes() As Boolean

The company has a Visual Studio 2010 Ultimate project that is written in Visual Basic. The project has several strings in the resources file (Resources.resx). One of those strings (VersionSuffix) contains "" when we are distributing a normal version of our product and "BETA" when we are distributing a beta version of our product. Most of the time we distribute a normal version of our product. Therefore, most of the time the resource string VersionSuffix contains "".
Recently, we attempted to distribute a beta version of our product. Therefore, we changed resource string VersionSuffix from "" to "BETA". However, it quickly became apparent that the resource string VersionSuffix was being used as the default value for several control properties in the form designer. For example, if I draw a rich textbox on a form then file FORMNAME.Designer.vb will contain the following.
Me.RichTextBox1.Location = New System.Drawing.Point(286, 306)
Me.RichTextBox1.Name = "RichTextBox1"
Me.RichTextBox1.Size = New System.Drawing.Size(134, 33)
Me.RichTextBox1.TabIndex = 32
Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
We are unable to find anything anywhere that indicates that this resource string should be used as the default value for control properties. Therefore, we have no idea why this resource string is being used for this purpose. We would like to change the control property assignments in the designer from Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix
Me.RichTextBox1.Text = "" However, we don't know why these strange assignments are being made. Therefore, as soon as someone adds another control the problem will most likely return. Does anyone know why this is happening and how to prevent it from happening again?

Long story short I made a form in VB.Net project which involves lots of icons and images. My problem is when I build my project, and then go back to that form, suddenly errors showed up.
The errors says : "The type 'MyProject.MyResources.Resources' has no property named 'myicon'". Just to be clear, it worked fine before I did the build, and it happened to every single images I have on Resource.
When I chose "Ignore and Continue" all of the images I used are gone. I tried to googled it, some says to delete my .exe file on Application/Bin/Debug folder, which is working. But this issue has been some kind of an annoying one, since it happens again every single time I build.

I use MS visual studio 2010. I did open designer and view the form for the same file A before. But after some small changes, I can no longer view the form designer.vb, but can only view code in designer.vb. Even if I go back to the original source, I still can not open designer!!
The error is: The designer could not be shown for this file because none of the classes within it can be designed. The designer inspected the following clsses in the file A-The base class BaseClass could not be loaded. Ensure the assembly has been referenced and all that projects have been built.
