how to make custom editor values appear when selecting more than one control

I created a custom control with extendable property "ButtonProperties " which has a custom form editor and it works perfectly fine
My proplem is when selecting more than one control the TextBoxes of the form will be blank instead of having values for the properties which are the same between the selected controls.
Notice: if all the properties are the same between all controls the values are appearing correctly

C#

public class ButtonEditor : UITypeEditor
    {

        public override UITypeEditorEditStyle GetEditStyle(System.ComponentModel.ITypeDescriptorContext context)
        {
            return
            UITypeEditorEditStyle.Modal;
        }

        public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
        {
            IWindowsFormsEditorService editorservice = provider.GetService(typeof(IWindowsFormsEditorService)) as IWindowsFormsEditorService;
            Complex_Editor form = new Complex_Editor();
            ButtonProperties inobj = new ButtonProperties();
            ButtonProperties outobj = new ButtonProperties();
            inobj = (ButtonProperties)value;
            try
            {
                form.Controls["txtbxbtnText"].Text = inobj.Text;
            }
            catch
            {
            }
            try
            {
                form.Controls["txtbxbtnWidth"].Text = inobj.Width.ToString();
            }
            catch
            {
            }
            try
            {
                form.Controls["txtbxbtnHeight"].Text = inobj.Height.ToString();
            }
            catch
            {
            }
            form.ShowDialog();
            if (Variables.ValuesChanged == true)
            {
                if (!string.IsNullOrEmpty(form.Controls["txtbxbtnText"].Text))
                {
                    outobj.Text = form.Controls["txtbxbtnText"].Text;
                }
                if (!string.IsNullOrEmpty(form.Controls["txtbxbtnWidth"].Text))
                {
                    outobj.Width = int.Parse(form.Controls["txtbxbtnWidth"].Text);
                }
                if (!string.IsNullOrEmpty(form.Controls["txtbxbtnHeight"].Text))
                {
                    outobj.Height = int.Parse(form.Controls["txtbxbtnHeight"].Text);
                }

For me it is not clear what the issue or the goal is.
Please explain it with further Information ... (or perhaps a screenshot).

Eng.Yahya92 6-Jul-15 2:33am

this code represents custom editor for a custom property in a custom control
the proplem is: in design time when I select more than one control then I go to the properties custom editor, the editor values which are the same between all selected controls are blank in the editor instead of being filled with value

Ralf Meier 6-Jul-15 2:46am

I understand the first part of it.
You build up your own UITypeEditor.
But the issue isn't clear for me.
But there is one Thing I have seen : why dont you give your UITypeEditor the customized property as one element ? - perhaps this is the Point ...

Ralf Meier 6-Jul-15 2:48am

Additional :
Show me also the declaration of the customized property and the Connection of/to your Editor ...

Eng.Yahya92 6-Jul-15 2:49am

because if there is some kind of failure I do not want the entire property to fail, instead a part of it will fail

Ralf Meier 6-Jul-15 3:05am

What kind of failure do you await ? What about a handling of these failure ?
Could you also Show me the declaration of your property ?

Eng.Yahya92 6-Jul-15 3:09am

usually wrong format values, I am not in need to handle them ( actually this control is just for training)
here is decleration of property
[RefreshProperties(RefreshProperties.Repaint)]
[Category("Line")]
[Browsable(true)]
public class ButtonProperties
{
public event PropertyChangedEventHandler propertChanged;

public override string ToString()
{
return "";
}
string btnText = "Button";
[Category("Line")]
[Browsable(true)]
[RefreshProperties(RefreshProperties.Repaint)]
public string Text
{
get
{
return btnText;
}
set
{
btnText = value;
Label1Properties_propertChanged("btnText");
}
}

int btnWidth = 80;
[Category("Line")]
[Browsable(true)]
[RefreshProperties(RefreshProperties.Repaint)]
public int Width
{
get
{
return btnWidth;
}
set
{
btnWidth = value;
Label1Properties_propertChanged("btnWidth");
}
}

int btnHeight = 80;
[Category("Line")]
[Browsable(true)]
[RefreshProperties(RefreshProperties.Repaint)]
public int Height
{
get
{
return btnHeight;
}
set
{
btnHeight = value;
Label1Properties_propertChanged("btnHeight");
}
}

void Label1Properties_propertChanged(string propertyName)
{
if (propertChanged != null)
propertChanged(this, new PropertyChangedEventArgs(propertyName));
}
}

Ralf Meier 6-Jul-15 3:30am

OK ... I thought that you have realized something of that we have spoken about last week. This is complete different ... :(

I asked the question because if you directly work with the original property you could use the context of the UITypeEditor to Access then "calling" property (by context.instance).
I think (but not sure know) that this will solve the issue ...

Eng.Yahya92 6-Jul-15 3:38am

I could solve the issue with some kind of stupid way using the context.instance.MyControl.ButtonProperties
I do not get what you mean
you see I created a class for CustomControl, then a class for CustomProperty with event that is fired in CustomControl class
then a CustomEditor class that emplements UITypeEditor and linked it with CusomProperty
so where is the bad part?

Ralf Meier 6-Jul-15 3:53am

Context.Instance is an Object which gives you a reference to your calling property. So you have to parse it first and then use it.

There is no "bad" part - I think you misunderstood me. I only awaited something different ...

Eng.Yahya92 6-Jul-15 3:55am

I did parsed it (y)
and what is it what you waited for ?

Ralf Meier 6-Jul-15 4:12am

Did it Change anything ?
Could you please improve your posted code above ?

Eng.Yahya92 6-Jul-15 4:14am

yes it solved the proplem ,, I told you but I feel that it is stupid
question is improved now

Ralf Meier 6-Jul-15 4:34am

I don't understand you ... what is stupid ...?

But your solution-code seems good - of course - if you select more than one property the context.instance gives you a list. I never tried that, but now I learned something too ;)

Eng.Yahya92 6-Jul-15 4:37am

thank you, glad to hear that :)
I feel it is stupid because it is not that much reusable
in another custom control for example.. I will have to custom edit it again

Ralf Meier 6-Jul-15 4:43am

That was the reason why I suggested you to work with only one Property for the communication with the Editor.

But at least (the point re-useable) :
Each Editor is only qualified to edit it's designated class. For example : you can't modify the Color-Property with the Size-Editor (or the other way round).

Eng.Yahya92 6-Jul-15 4:45am

I mean different CustomControl with the same CustomProperty

Ralf Meier 6-Jul-15 5:11am

It must work with every Property which has the same Type.
Why does it not work with another Property ?
How is your Property-Declaration itself ? - not the Property-class ...

Eng.Yahya92 6-Jul-15 5:39am

another Control I ment

Ralf Meier 6-Jul-15 6:25am

That's the same - just as the Color- or Size-Example I spoke about ...
It's a question of Base-Class or Interface ...

Eng.Yahya92 6-Jul-15 3:00am

this it the editor when selecting more than one of "MyCustomControl" on GUI although they have the same value of height and width
