Jeff,
I would suggest you to handle the GettingCellValue event of template column to return the value. This event is used to provide the cell value to export.
Thanks,
Deepak Sharma

Reply To: Exporting templated column header to Excel
Deepak,
Thank you for your response.
Actually I’m not using template columns, I just assign a "complex" (a grid and a label inside the grid) control hierarchy to the column’s header property instead of the basic string value.
DOTY_Grid.Model.utils.CustomHeaderGrid grid = new DOTY_Grid.Model.utils.CustomHeaderGrid(); grid.Path = e.Column.Binding.Path.Path; TextBox txtBoxHeader = new TextBox(); Converters.ApplyColumnHeaderStyle(grid, txtBoxHeader, modelColumn.HeaderStyle); txtBoxHeader.SetBinding(TextBox.TextProperty, headerBinding); txtBoxHeader.KeyDown += new KeyEventHandler(txtBoxHeader_KeyDown); grid.Children.Add(txtBoxHeader); e.Column.Header = grid;
Except that, everything else (including the column type) is being taking care of by the Grid.
Do you have another way to solve my problem in this context ?
Thanks,
-jeff.

Feature Request: Project-Level Dictionary
A project/solution level dictionary would be very helpful.
A quick solution might be an option to use either the global dictionary or a 'local’ dictionary defined for the solution.
A more comprehensive solution would allow defining the dictionary for each project with the option of adding words to the global or local dictionary.

C1NumericEdit problem with EmptyAsNull and getting a Value of zero when del Text
Hi,
Environment:
Win7
C1.Win.C1Input.2.dll version 2.0.20112.33265
C1.Win.C1TrueDBGrid.2.dll version 2.0.20112.61272
I’m using a custom editor (that I assign programmatically to a TrueDB column) like this:
foreach (Split split in defaultGrid.Grid.Splits)
{
C1DisplayColumnCollection dcc = split.DisplayColumns;
C1DataColumn DC_DEFAULT_VALUE = defaultGrid.Grid.Columns[DF_DEFAULT_VALUE];
int displayColumnDefValIndex = dcc.IndexOf(DC_DEFAULT_VALUE);
C1DisplayColumn c1dcDefVal = dcc[displayColumnDefValIndex];
C1NumericEdit c1ne = new C1NumericEdit ();
c1ne.NullText = "";
c1ne.EditMask = "###,###";
c1ne.FormatType = FormatTypeEnum.CustomFormat;
c1ne.EditFormat.CustomFormat = "###,###";
c1ne.DisplayFormat.CustomFormat = "###,###";
c1ne.ParseInfo.CustomFormat = "###,###";
c1ne.ParseInfo.NumberStyle = NumberStyleFlags.Currency;
c1ne.ParseInfo.FormatType = FormatTypeEnum.StandardNumber;
c1ne.ParseInfo.NumberStyle = NumberStyleFlags.Currency;
c1ne.Update();
c1ne.Location = new Point(100, 100);
c1ne.Name = "editor_pe";
c1ne.Size = new Size(100, 20);
c1ne.TabIndex = 0;
c1ne.Tag = null;
c1ne.VisibleButtons = DropDownControlButtonFlags.None;
c1ne.EmptyAsNull = true;
…
}
The type of the DC_DEFAULT_VALUE display column data field is Decimal. I expect the field to show/handle values from -999,999 to +999,999 Well, when click on a TrueDBGrid cell under the DC_DEFAULT_VALUE column and just type the minus sign (-) and tab out to the next cell, I get zero (o) in the cell?!? Once I get a zero in the cell, I can’t even delete this via Backspace and/or Delete buttons! This must be a bug since I specify EmptyAsNull = true;
Please, help me with this issue. Thanks.
Regards,

Drag Drap Manager with a Grid
I have a grid set up for DragDrop operations just like the sample. The sample works great. However, in my app, it works slightly different and I don’t see why.
In the sample, you can easily drag and drop a textblock to a different row/column in the grid and it moves just fine.
In my app, I can drag around the grid, but it only lets me drop over an existing element in the grid. This is fine, but there are the areas of the grid that are empty. When I drag over these areas, the DragLeave event is fired, and the drop operation is not allowed, and the orange drag border is dimmed. In other words, it thinks it is not an area where it should be dropped.
_dragDropManager.RegisterDropTarget(_uiRoot, true);
The _uiRoot is the grid. This is the code that registers it.
_dragDropManager.RegisterDragSource(border, DragDropEffect.Move, ModifierKeys.None);
Any suggestions appreciated.
Greg

Reply To: Drag Drap Manager with a Grid
To clarify, what I mean during the drag operation, if the grid has an UIElement in the grid, such as a TextBlock, it sees that as a valid drop target. But if a grid cell is empty, it sees it as not a valid drop target and doesn’t let the drop occur.

CustomColumns and XAML Rows
Hi.
I am facing a problem with specifing rows in XAML, when working with celltemplates
My pasted XAML only results in this blank space... tested with IE10 and FF20.0.1
See attached File instead
With this XAML the Rows in the C1FlexGrid.Rows collection do not display the columns I specified threw the celltemplates. Once I use the ItemsSource property and populate it with an IEnumerable it works.
How can let C1FlexGrid display the columns correclty when declaring the rows in XAML?
Hope you can help me out.
Thanks in advance.

Field with CanGrow = True ignores left align on multipage document

On the first page is everything OK, but on second one it ignores Left property and render itself same as with Left = 0. I tried place a Line on the left side of the Field, but then it appears same as with KeepTogether = True, which totaly screw layout. You can see this in attached example on page 3.
