GridView with RowDetails

[Richard Slade]

Hi, 

I'm trying to replicate the RowDetails grid that is in the demo. It works in that a row details row is shown under each row correctly, but I'm having an issue
The column that I am using as the RowDetails column is still showing it's header and has a blank area
If I set the column to IsVisible=False, then the RowDetails don't show. 


I've attached a pretty crude screenshot (it's just a test before I put this into our main project) 
Thanks all 
Richard

Hello Richard,

I'm guessing you forgot this:

public GridViewDataColumn DetailsColumn

        {

            get

            {

                return this.detailsColumn;

            }

            set

            {

                if (detailsColumn != value)

                {
                           detailsColumn = value;

                    if (detailsColumn != null)

                    {
                                 detailsColumn.MinWidth = 0;

                        detailsColumn.Width = 1;

                        detailsColumn.ReadOnly = true;

                    }



                    this.TableElement.Update(GridUINotifyAction.Reset);

                }

            }

        }

You should just set the width, minWidth, maxWidth to 0 and it should solve your problem.

Hope this helpls,
Best Regards,

Thanks for the reply... No, I copied from the demo this.. 

Public Property DetailsColumn() As GridViewDataColumn
    Get
        Return Me.detailsColumn_Renamed
    End Get
    Set(ByVal value As GridViewDataColumn)
        If detailsColumn_Renamed IsNot value Then
            detailsColumn_Renamed = value
            If detailsColumn_Renamed IsNot Nothing Then
                detailsColumn_Renamed.MinWidth = 0
                detailsColumn_Renamed.Width = 50
                detailsColumn_Renamed.ReadOnly = True
            End If
            Me.TableElement.Update(GridUINotifyAction.Reset)
        End If
    End Set
End Property

Hello again,

This is fun, they made a mistake on the vb side, just try what i sent you, put the width = 0 and maxWidth = 0 and let me know, ok?

ah yes, well spotted. Thanks!

hmm, thought that would have got it.. but hasn't. Will try again Monday. 

Public Property DetailsColumn() As GridViewDataColumn
    Get
        Return Me.detailsColumn_Renamed
    End Get
    Set(ByVal value As GridViewDataColumn)
        If detailsColumn_Renamed IsNot value Then
            detailsColumn_Renamed = value
            If detailsColumn_Renamed IsNot Nothing Then
                detailsColumn_Renamed.MinWidth = 0
                detailsColumn_Renamed.Width = 0
                detailsColumn_Renamed.MaxWidth = 0
                detailsColumn_Renamed.ReadOnly = True
            End If
            Me.TableElement.Update(GridUINotifyAction.Reset)
        End If
    End Set
End Property

Hello again,

Sorry, I've got that wrong the width and maxWidth should be 1 NOT 0.

This will work, I've just tested it and it's OK, it's just strange in one way but it's normal in another way because if it is 0 then visible should be false and then you will have no date.

That's got it. Thanks for your effort. Not obvious though eh!?

Hi Emanuel

Any ideas how to get all the rows to pre-expand to show the details column please? I've only got a few rows and would like them to all be expanded by default. 
Cheers
Richard

not to worry, answered my own question

Public Overrides Sub UpdateInfo()
    Me.RowInfo.Height = (CType(Me.GridControl, RowDetailsGrid)).DetailsRowHeight
    'If (Not Me.RowInfo.IsCurrent) Then
    '    'Me.RowInfo.Height = TableElement.RowHeight
    'Else
    '    Me.RowInfo.Height = (CType(Me.GridControl, RowDetailsGrid)).DetailsRowHeight
    'End If
    MyBase.UpdateInfo()
End Sub

Hello Richard,

Have you tried already with going trough all the rows and setting IsExpanded = true?

row.IsExpanded = true;

I am thinking it should be like for hierarchical grids, like this article explains...

Sorry but I cannot test it right now, i will try to take a look soon if this is not working, please let me now, ok?

Thanks for the quick reply. It's fine though. The one I posted above works fine.
