datagrid

问题 I want to add an extra row to Datagrid's header row that will contain textboxes (for searching). This row should appear directly under the original header and look like regular item header. This is my code so far: <Window.Resources> <Style x:Key="DataGridColumnHeaderStyle1" TargetType="{x:Type DataGridColumnHeader}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type DataGridColumnHeader}"> <Grid VerticalAlignment="Center" HorizontalAlignment="Stretch"> <Grid

问题 I desire to make data grid with one column representing rather lengthy text values. So my goal functionality is: Column width to be as wide as remaining window space (window can be re-sized) Word-wrap text as necessary Limit data grid height to remaining height of window and provide vertical scroll as necessary The following code meets the first two items and provides a functioning vertical scroll bar, but the data grid height is bizarrely too tall for the content it is showing. Removing word

问题 I have a TabControl which contains a StackPanel with many Expander. In each Expander I placed an UserControl. So, I have a clear view. The UserControl contains a DataGrid. Now, the problem is, that the height from the DataGrid is not set. If the DataGrid is lager than the window-size no Scrollbar is shown. <TabControl SelectionChanged="Selector_OnSelectionChanged" Height="Auto"> <TabItem Header="DoSmth"> </TabItem> <TabItem Header="Misc" Height="Auto"> <StackPanel Height="Auto"> <Expander

问题 I know that DataGrid supports virtualization, so it creates grid cells only for visible rows. However, this seems to work only if the DataGrid is constrained in size. In my scenario, a DataGrid is placed inside a scroll-viewer, like so <ScrollViever> <StackPanel> <more elements .../> <DataGrid ... /> <more elements .../> </StackPanel> </ScrollViever> This seems to break virtualization. In cases where the DataGrid should display a large number of items, the visual tree becomes very very large,

问题 I have a form, it has a grid. I autogenerate the columns and tweak them as required: if (e.PropertyName == "id") { System.Windows.Style style = new Style(typeof(DataGridCell)); style.Setters.Add(new Setter(DataGridCell.ContentTemplateProperty, CreateBtnTemplate(30))); e.Column.CellStyle = style; } private static DataTemplate CreateBtnTemplate(int width) { string str = "<DataTemplate xmlns='http://schemas.microsoft.com/client/2007' >" //+ "<Button Tag='{Binding id}' Content='Respond' + "

问题 I am using LINQ to SQL with a Datagrid and binding the data to the auto generated fields. The data updates fine when when submitting changes via LINQ.
