Hi,
I have widely used ToolStrip in my application. I created a UserControl which contains this ToolStrip. I would rather like to use inheritance:
MyCustomControl : ToolStrip
Everything seems to work fine, untill I want to set visibility to one of ToolStripItem - there are maybe 20 buttons and not all of my ChildForms which contains this MyCustomControl need all of them. I open in designer mode in Property window "Items", choose right one and than select "Visibility" > false. In designer mode button dissapear. When compile, designer is reloaded, button is back again.
If I code manually in constructor of ChildForm:
myCustomControl.Items["someButton"].Visible = false;
it worsk OK.
What would you advice me, please? - Moved byHarry ZhuMSFTTuesday, September 22, 2009 8:53 AMrelating to custom control (From:Visual C# General)

Eyal, Regards.

Could you give me advice, please? | | lukas43 Saturday, September 19, 2009 8:24 AM | Can you post some code ? such as the Custom Control, and a sample code that reproduces the problem ? it's hard to guess here. Compiling the code shouldn't change anything that relates to the designer, unless you handle the designerin a flaw, or it's not even related to the actual compilation, and you set some default value that overrides the visibility value.
Eyal, Regards.
blog.eyalsh.net | | Eyal-Shilony Saturday, September 19, 2009 8:41 AM | Compile did not. Visual Studio did - when I changed through designer property of item and save window, in MyForm.designer.cs I did not found corresponding record, such as:
this.myCustomControl.ToolStripItem1.Visible = false;
I see it like Visual Studio does not create this record in .designer for specific situations and this is one of those. For other custom controls inheriting from .NET such as myTextBox : System.Windows.Forms.TextBox works everything great... | | lukas43 Saturday, September 19, 2009 2:16 PM | It's a bit confusing, you were speaking about the ToolStrip, and now this piece of code is actually an item representing a child of the ToolStrip, it's an abstract class which is not likely to be produced by Visual Studio, at least not in that context, however having a collection of type 'ToolStripItem' is very much possible.
Things will be much more easier if you can just describe what you're trying to do, better, providing some code samples, so we can work it out. :)

public partial class FormMenu : ToolStrip, ILoadable
Constructor:
public FormMenu()
{
InitializeComponent();
this.tsiFirst.Enabled = false;
this.tsiPrevious.Enabled = false;
this.tsiSave.Visible = false;
this.tsiBack.Visible = false;
this.tsiRestore.Visible = false;
this.tsiExport.Visible = false;
this.tsiYears.Visible = false;
oPaging = new PagingItem(tsiFirst, tsiPrevious, tsiNext, tsiLast, tsiPage, tsiFrom);
}
Property of object:
[Browsable(true)]
public ToolStripItem Trash
{
get { return tsiTrash; }
}
I include this control in my forms. Everything works fine.. In Form, which contains this "menu" I try to change Trash buttons visibility. Property is visible in Visual Studio designer, I use standard methods - go to property window, and change Visible to False. When I save file, open Form.designer.cs I dont see generated record for this change. When I build, VS reloads window and property Visible is back to True. | | lukas43 Sunday, September 20, 2009 7:11 AM | If you want Visual Studio to automatically generate code for an object, you will have to handle the designer, and probably serialize, deserialize the object, you may want to check the DesignerSerializationVisibilityAttribute, EditorAttribute and TypeConverter if so needed.
You can try and add this to the property.
[System.ComponentModel.DesignerCategory("code")]
[ToolStripItemDesignerAvailability(ToolStripItemDesignerAvailability.ToolStrip | ToolStripItemDesignerAvailability.StatusStrip)]
