Listview width with or without vertical scrollbar

I have a RadListView, with a ViewType of Listview, and VerticalScrollBar set to AutoHide. I simply want to get the width of the control including the scrollbar if visible.

I have tried ClientRectangle.Width - it did not take into account the scrollbar.width

So I tried checking the visibility of the scrollbar, if visible then subtract the scrollbar width. Even when the scrollbar is visible, it always comes back as Visible=False.

Is this a bug or am I doing wrong something wrong?

Dim iScroll As Integer = 0

'get scrollbar width if needed

If Me.lvwLoadForms.VerticalScroll.Visible = True Then iScroll = SystemInformation.VerticalScrollBarWidth

'resize items and group widths

With Me.RadListView1

.GroupItemSize = New Size(.Width - iScroll, .GroupItemSize.Height)

.ItemSize = New Size(.Width - .GroupIndent - iScroll, .ItemSize.Height)

End With

ListView

GridView ImageColumn not showing image

Hi,

I've already performed a search here, and I think I'm doing this right, but the fact is that my RadGridView does not show the image.
The only thing that the field shows is "System.Drawing.Bitmap"

'Loading image from file ( path in database )

Dim img As Image = Image.FromFile(Reader("Imagem"))

'Attempt 1

r.Cells(2).Value = img

'Attempt 2

'Writing to a memory stream

Dim ms As New MemoryStream

img.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)

'passing the bytes to the value field

r.Cells(2).Value = ms.ToArray

'Attempt 3

'Simply loading an image from resources to the value field

r.Cells(2).Value = My.Resources.icon_fantasma_05

I know I'm doing something wrong, I just don't know what. These 3 attempts , are based / copy from examples given on the intermet..
I've attached a image, which shows what I'm getting at the GridView.

Could somebody please help?

Thank you very much !

Add extra column for input below another column in gridviewrelation

Hi,

We use a gridview with a gridviewrelation.

The Case:

We have a list of projects, for each project we have employees working on a specified project.
For each week they have to put amount of hour(s), W1 -2014, etc... (see picture)
We have also a column W1Description2014 etc... we want to add this below the column of W1-2014, etc...

See picture for more information.

This is de code we use to add the grid relation:

Dim MyProjectRelation As New GridViewRelation(MyBase.SearchGrid.MasterTemplate, template)
MyProjectRelation.RelationName = "ProjectRelations"
MyProjectRelation.ParentColumnNames.Add("projectnr")
MyProjectRelation.ChildColumnNames.Add("projectnr")

In telerik screenshot we see difrent styles, but we can't find this issue in code.

Do you have any solution for this issue ?

With friendly regards.

            or
            RadGridView1.MasterTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill

            is it possible to fit 100%?

Thank You

Showing hidden tabbed documents

I am trying to provide a hide and show functionality with tabbed DocumentWindow instances.

The idea is to hide all DocumentWindow instances except one, and then later re-show all the hidden DocumentWindow instances.

The issue is that after hiding them, these windows are no more accessible through the Dock object.
Even when I add the following line when I create a new DocumentWindow instance.

documentWin.CloseAction = DockWindowCloseAction.Hide;<br>

It seems as if the Hide() method actually closed the DocumentWindow.

Appreciate any help on this issue.
Thanks

Deselect doesn't fire SelectionChanging

Note: SelectionMode is "FullRowSelect".

Example:
Let us assume the user has 3 rows selected and the "CurrentCell" is the second cell on the third row.

If the user holds Ctrl and clicks the second cell of the third row (still CurrentCell), then the third row will be deselected (highlight goes away).

However, mygrid.SelectedRows.Count is still 3 and SelectionChanging does not fire!

If the user had instead held Ctrl and clicked any other cell in the third row, the visual update is the same but the grid will additionally fire the SelectionChanging event and SelectedRows.Count will be 2, as expected.

This seems like a bug, how can I make this functionality be made more intuitive for the end user?

How do I do that?
