So I've fumbled my way through using a RibbonControlHost to put a DateTimePicker on a Ribbon.

Public Class DTPControlHost
    Inherits C1.Win.C1Ribbon.RibbonControlHost
    Public Sub New()
        MyBase.New(New System.Windows.Forms.DateTimePicker())
    End Sub
End Class

Now I can place the control on the ribbon with MyProject.DTPControlHost, but ...

The DateTimePicker has a format property that I can set (when it is not hosted) by

DateTimePicker.Format = DateTimePickerFormat.Short

How can I get at that property in a hosted control, either by settng in the class or in the form load?

This must be part way there ... lets me set the property but the control displayed doesn't change?

Public Class DTPControlHost

Inherits C1.Win.C1Ribbon.RibbonControlHost

Public Sub New() MyBase.New(New System.Windows.Forms.DateTimePicker())

End Sub

Public ReadOnly Property DateTimePicker() As DateTimePicker

Get

Return CType(Control, DateTimePicker)

End Get

End Property

Public Property Format() As DateTimePickerFormat

Get

Return DateTimePicker.Format

End Get

Set(ByVal value As DateTimePickerFormat)

value = DateTimePicker.Format

End Set

End Property

End Class

Ah ...

Have to set the property when using the control like this ...

DtpControlHost_Start.DateTimePickerControl.Format = DateTimePickerFormat.Short

You can type

DtpControlHost_Start.Format = DateTimePickerFormat.Short

but it won't work ...

Hope this helps someone else!

> Public Property Format() As DateTimePickerFormat
> Get
> Return DateTimePicker.Format
> End Get
> Set(ByVal value As DateTimePickerFormat)

The next line was incorrect:

> value = DateTimePicker.Format

It should be changed to:

DateTimePicker.Format = value

> End Set
> End Property

Riiight.

So if I'd done that correctly, I can use DtpControlHost_Start.Format

Question - the RibbonControlHost can't be put into a Toolbar in a Group, can it? I'd like to be able to put labels on these but I haven't managed that as yet.

Yes. RibbonControlHost can't be added to the RibbonToolBar.
I will add this item to our to-do list.

Thanks.

We have had excellent success using the RibbonControlHost to place a C1FlexGrid inside the ribbon. - Our language is C#

The reason for the flexgrid is to provide an adaptable column on/off filter for the flexgrid and/or chart that is displayed below the ribbon. Hence the height of the flexgrid is only 2 rows high and does not conflict with the ribbon group maximum height.

Here is the code...

using C1.Win.C1FlexGrid;

using C1.C1Preview;

namespace StrategyMap

{

public partial class frmExportToGrid :Form

{

public frmExportToGrid()

{

InitializeComponent();

}

class FlexGridHost : C1.Win.C1Ribbon.RibbonControlHost

{

public FlexGridHost() : base(new C1FlexGrid())

{

}

[Browsable(false)]

[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]

public C1FlexGrid C1FlexGrid

{

get { return (C1FlexGrid)Control; }

}

}

 

#region Global Variables

--------

 

Here is the Click event, note that we deal directly with the flexgrid here...

private void flxColumnFilter_Click(object sender, EventArgs e)

{

Point pt = Control.MousePosition;

pt = flxColumnFilter.C1FlexGrid.PointToClient(pt);

HitTestInfo hti = flxColumnFilter.C1FlexGrid.HitTest(pt.X, pt.Y);

int iRow = hti.Row, iCol = hti.Column;

bool ColIsVisible = Utilities.Convert_ToBoolean(flxColumnFilter.C1FlexGrid[1,iCol].ToString());if (iRow == 0)

{

ColIsVisible = !ColIsVisible;

flxColumnFilter.C1FlexGrid[1, iCol] = ColIsVisible;

}

flxExport.Cols[iCol-1].Visible = ColIsVisible;

}

------------

Here is where we setup the flexgrid...

flxColumnFilter.Width = 960; // adjust the ribbon group width - note that we dealt with the flexgrid directly to set the group size

flxColumnFilter.C1FlexGrid.Clear(); // now we need to deal woth the C1FlexGrid object to set special properties

flxColumnFilter.C1FlexGrid.Redraw = false;

if (flxExport.Rows.Fixed > 0) ColumnNameRow = flxExport.Rows.Fixed - 1;

flxColumnFilter.C1FlexGrid.AllowSorting = AllowSortingEnum.None;

flxColumnFilter.C1FlexGrid.Height = 60;

flxColumnFilter.C1FlexGrid.Rows.Count = 2;

flxColumnFilter.C1FlexGrid.Rows.Fixed = 1;

flxColumnFilter.C1FlexGrid.Cols.Count = flxExport.Cols.Count+1;

flxColumnFilter.C1FlexGrid.Cols.Fixed = 1;
