CancelEdit() on DataGrid raises System.InvalidOperationException: An attempt was made to call the CancelEdit method on a DataGridContext that is not current.

Daniel — Fri, 21 Dec 2012 11:24:55 GMT

Today I do some test nad I have found, that calling of method CancelEdit() of DataGridControl raises System.InvalidOperationException: An attempt was made to call the CancelEdit method on a DataGridContext that is not current.
at Xceed.Wpf.DataGrid.DataGridControl.CancelEditHelper(DataGridContext dataGridContext)
at Xceed.Wpf.DataGrid.DataGridControl.CancelEdit()

This happens when there is edited any value in child row, and focus reamins on that row (row remains in editing state).

What can be reason for that behaviour? I how can I avoind that exception, and correctly cancel editing?

How can I tell a DataCell is shortening its content

Stephen — Wed, 31 Oct 2012 15:15:36 GMT

Is there a way to know if a DataCell is shortening its content?For example, If I have a cell that has "1234567890" for the content, but it can't all fit, then it displays like this: "123456..."

I need to know when that is happening so I can turn on the tool tip FOR ONLY THAT VALUE.

I would check for ... in the text, but I can't find a "DisplayValue" property for the DataCell. Only the actual content.

As a side note, this would be a good feature to add to the grid (turn on tool tips for rows that are using the ellipsis to shorten the value) .

--------

NOTE: Right now I am using this code, but it has to measure the string each time AND it is not accurate. When the ellipsis is just starting to be shown it will still not show the tool tip.

        private void OnCellMouseEnter(object sender, MouseEventArgs e)
        {
            Xceed.Wpf.DataGrid.DataCell cell = sender as Xceed.Wpf.DataGrid.DataCell;
            if (cell == null) return;
            if (cell.Content == null) return;
 
            double cellTextWidth = CalculateStringLengthForCell(cell, cell.Content.ToString());
 
            if (cellTextWidth > cell.ActualWidth)
            {
                cell.ToolTip = cell.Content.ToString();
            }
            else
            {
                cell.ToolTip = null;
            }
        }

        private double CalculateStringLengthForCell(DataCell cell, String text)
        {
            
            FormattedText formattedText = new FormattedText(cell.Content.ToString(), System.Globalization.CultureInfo.GetCultureInfo("en-us"), FlowDirection.LeftToRight,
                                                new Typeface(cell.FontFamily, cell.FontStyle, cell.FontWeight, cell.FontStretch), cell.FontSize, cell.Foreground);
 
            return formattedText.Width;
        }

How to keep shadow of the header follow the mouse?

Jia — Thu, 21 Jun 2012 07:56:45 GMT

Hi,

I am just update my xceed version to 4.3 now. However, I met the issue after that.

I integrated the data grid to one windowsForm project.

Then I drag the column header and want to group the values.

The shadow of the column header does not follow my mouse.

How to change it to let the shadow follows my mouse all the time?

How to conditionally display a CardFlow3D or TableView in Xaml?

Todd — Mon, 26 Mar 2012 15:21:03 GMT

I would like to conditionally display either a CardFlow3D view or a TableView in my control, based on the value of one of my ViewModel's properties. I don't need to support switching back and forth, but only need to make the distinction on load. I'd prefer to be able to do this entirely in xaml, since we are trying to keep our view's code behind clean, and do not want to put any display logic in our viewmodel.

formating cell content using StringFormatConverter truncates the result

Jonathan — Fri, 13 Jan 2012 23:22:08 GMT

using this xaml to ensure a double value is rounded to 2 decimal places

                <xcdg:StringFormatConverter x:Key="stringFormatConverter" />
                <s:String x:Key="roundDouble">{0:0.00}</s:String>
                
                <DataTemplate DataType="{x:Type s:Double}">
                    <TextBlock Text="{Binding Converter={StaticResource stringFormatConverter}, ConverterParameter={StaticResource roundDouble}}" 
                               HorizontalAlignment="Right" />

</DataTemplate>

for example a cell content with -155.234567 should be displayed as as -155.23

but instead I see this -155...

Its as if the cell thinks it does not have enough room for the string and truncates adding the ..

What am I doing wrong here or what else do I need to do to ensure the cell displays what I want.

btw my columns are defined dynamically at run time so I cant or its not easy to set the format at compile time using a column definition or a CellContentTemplate
