Youmust apply an System.ComponentModel.Editor attribute on your property. Also, you must add a reference to the following assemblies: System.dll, System.Drawing.dll and System.Design.dll.

private string _fileName;

[System.ComponentModel.Editor(

typeof(System.Windows.Forms.Design.FileNameEditor),

typeof(System.Drawing.Design.UITypeEditor))]

public string FileName

{

get { return this._fileName; }

set { this._fileName = value; }

}

Visual Basic

Dim _fileName As String

<System.ComponentModel.Editor( _

GetType(System.Windows.Forms.Design.FileNameEditor), _

GetType(System.Drawing.Design.UITypeEditor))> _

Public Property FileName() As String

Get

Return Me._fileName

End Get

Set(ByVal value As String)

Me._fileName = value

End Set

End Property

you can Add 2 read-only properties with PATH and Filename.

When you select the FULL Path you'll set the right values of this properties in this way everything will works.

Thank for help it is very useful,I have one last problem for this. How I can filter at this point. I want to filter for .dxf files.

Toachieve thisyou mightcreate your own editor by inheriting from UITypeEditor.

public class CustomFileNameEditor : UITypeEditor

{

public CustomFileNameEditor()

{

}

private string _customFilter = "My files(*.dxf)|*.dxf";

[DefaultValue("My files(*.dxf)|*.dxf")]

public string CustomFilter

{

get { return _customFilter; }

set { _customFilter = value; }

}

public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)

{

// We'll show modal dialog (OpenFileDialog)

return UITypeEditorEditStyle.Modal;

}

public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)

{

using (OpenFileDialog dialog = new OpenFileDialog())

{

dialog.Filter = this.CustomFilter;

if (dialog.ShowDialog() == DialogResult.OK)

value = dialog.FileName;

}

return value;

}

The drawback of this approach is that you cannot define the custom filter in design time directly, insteadyou can create a property on your componentand use the IDictionaryService to store it.

If you choose to define a property on your component to store the filter (you'll have to specify on each component even if they are in the same container) you caninsert before theassignment from above (dialog.Filter = this.CustomFilter) the following lines of code:

if (context.Instance is UserControl)

{

this.CustomFilter = (context.Instance as MyUserControl).CustomFilter;

}
