I have <DataGrid Name="grid" MouseDoubleClick="Attributes_MouseDoubleClick" > I need to unselect a row whenever a click event occurs anywhere else other than the Datagrid row. i.e. grid.CurrentItem should be null I need to fire a double-click event only on a row. But, the problem is, once I select a row and double-click elsewhere on the grid(header, empty scrollviewer area, etc) the double-click event fires as expected but the CurrentItem is sometimes the selected row and sometimes null. To prevent this behaviour.. I need to unselect the selected row. Any ideas as to how I should approach this

I have a DataGrid, with columns XAML as such: <DataGridTextColumn Header="Time" Binding="{Binding Date, StringFormat='yyyy-MM-dd HH:mm:ss'}" SortMemberPath="Date" SortDirection="Descending" Width="130" CanUserResize="True" /> <DataGridTextColumn Header="Level" Binding="{Binding Level}" Width="60" CanUserResize="True" /> <DataGridTextColumn Header="Source" Binding="{Binding Logger}" Width="150" CanUserResize="True" /> <DataGridTextColumn Header="Message" Binding="{Binding Message}" Width="*" CanUserResize="True" /> I bind this to an ObservableCollection<EalsLogEvent> , where EalsLogEvent.Date

I have a customized vertical scrollbar which displays markers for selected items in a DataGrid. The problem I'm facing is, when there are a great number of items (e.g. could be 5000 to 50000) there is a lag while it is rendering the markers. With the following code it basically renders as per the selected items index, number of items and height of the track. Obviously this is inefficient and am looking for other solutions. This is my customized vertical scrollbar <helpers:MarkerPositionConverter x:Key="MarkerPositionConverter"/> <ControlTemplate x:Key="VerticalScrollBar" TargetType="{x:Type

I have a DataGrid WPF control and I want to get a specific DataGridCell . I know the row and column indices. How can I do this? I need the DataGridCell because I have to have access to its Content. So if I have (for example) a column of DataGridTextColum , my Content will be a TextBlock object. You can use code similar to this to select a cell: var dataGridCellInfo = new DataGridCellInfo( dataGrid.Items[rowNo], dataGrid.Columns[colNo]); dataGrid.SelectedCells.Clear(); dataGrid.SelectedCells.Add(dataGridCellInfo); dataGrid.CurrentCell = dataGridCellInfo; I can't see a way to update the contents
