Re: ListView in a UserControl

Hi Nicholas !


Thanks for your answer. I tried what you said, and Visual Studio returns
me some error... I use Visual Studio 2003, prehaps this is the point.

Anyway, I see my collection on the parameter window of the designer and
when I click on it I have a wizard which helps me to create new columns. As
far as I don't close the designer, I can see my columns on my form painted
on Visual Studio. But when I launch my application or close/reopen the
designer, I have lost all my columns.

I guess the set() part of my parameter is wrong, but I don't know what
to do...

Thanks again ! :)

Laurent,

Two things first. One, your property should be public, otherwise, I
don't know how the designer is going to be able to access it.

Two, when you make it public, you will want to name it MyColumns, as
per the public naming convention.

That being said, you need to attach the following attributes to your
MyColumns property:

[MergableProperty(false), Localizable(true),
DesignerSerializationVisibility(DesignerSerializationVisibility.Content),
Editor("System.Windows.Forms.Design.ColumnHeaderCollectionEditor,
System.Design, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=b03f5f7f11d50a3a", typeof(UITypeEditor)),
SRDescription("ListViewColumnsDescr")]

This will enable the property window to help with designing your
columns.

Hope this helps.

Hello,


I'm creating a control including a listview. I would like to be able
to set the columns through the Design Tool in Visual Studio, so I created
a parameter to access the columns of my listview:

private ListView.ColumnHeaderCollection myColumns
{
get
{
return(this.myListView.Columns);
}
set
{
this.myListView.Columns.Clear();

foreach(ColumnsHeader column in value)
{
this.myListView.Columns.add(column);
}
}

Of course this is not working, I can insert my columns in the
designer, but when I launch my application, the collection is empty. I'm
sure what I did is dirty, but I don't know what to do... If someone has a
clue...

Thank !

Laurent
