Select arbitrary text in a WPF datagrid row or cell and copy it
Scenario:
I have an ObservableCollection containing log events. A log event consists out of eg time, date, severity and a message. I am using a WPF datagrid with data binding to display the content of the ObservableCollection.
Problem:
As an end-user I would like to mark/select arbitrary amounts of text in one row and copy it to the clipboard. For an example I would like to select single words in the message column or the whole row like it is possible in excel or html rendered tables.
Already tried:
I have tried to change the template for the cells to a readonly textbox which makes it possible to mark the whole cell or single words but then selecting and copying the whole row does not work anymore. I have also considered using the "FlowDocument" control but a major feature of the UI is that new log messages are added without repainting the whole control. As far as I know this is not possible with FlowDocument which also lacks data binding support.
Question:
How to display a list of (for an example) log events in WPF where one can select and copy arbitrary text portions like it would be possible in Excel or a rendered html table?
Could try this property:
<DataGrid SelectionUnit="Cell">
ADDED:
<DataGrid ItemsSource="{x:Static Fonts.SystemFontFamilies}" SelectionUnit="Cell" AutoGenerateColumns="False">
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Mode=OneWay}"/>
<DataGridTextColumn Binding="{Binding Baseline}"/>
<DataGridTextColumn Binding="{Binding LineSpacing}" Width="*"/>
</DataGrid.Columns>
</DataGrid>
To select an entire row at time and copy to clipboard
<DataGrid ... SelectionUnit="FullRow" CopyingRowClipboardContent="dataPaths_CopyingRowClipboardContent">
calls
private void dataPaths_CopyingRowClipboardContent(object sender, DataGridRowClipboardEventArgs e)
{
IList<DataGridCellInfo> cells = (sender as DataGrid).SelectedCells;
foreach (DataGridCellInfo cell in cells)
e.ClipboardRowContent.Add(new DataGridClipboardCellContent(e.Item, cell.Column, null));
//or write out to a log
foreach (var row in e.ClipboardRowContent)
Console.WriteLine(row.Item.toString());
}
