FindVisualChild method is not provided by WPF framework, you have to add them. May be you want this: public static IEnumerable<T> FindVisualChildren<T>(DependencyObject depObj) where T : DependencyObject { if (depObj != null) { for (int i = 0; i < VisualTreeHelper.GetChildrenCount(depObj); i++) { DependencyObject child = VisualTreeHelper.GetChild(depObj, i); if (child != null && child is … Read more
Firstly, this should be easy… secondly, why are you building (and binding) columns in C#? Eek. XAML (I’m using a regular grid because I’m lazy): <ListView Name=”MyListView”> <ListView.View> <GridView> <GridView.Columns> <GridViewColumn DisplayMemberBinding=”{Binding Operation}” /> <GridViewColumn> <GridViewColumn.CellTemplate> <DataTemplate> <ComboBox ItemsSource=”{Binding Choices}” /> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView.Columns> </GridView> </ListView.View> </ListView> C#: void Window1_Loaded(object sender, RoutedEventArgs e) { … Read more
Jared’s answer is correct, but I’ve found a concrete solution that’s solved my problem. http://blogs.msdn.com/vinsibal/archive/2008/12/17/wpf-datagrid-dynamically-updating-datagridcomboboxcolumn.aspx Following this example, I changed my DataGridTextColumn definition to: <dg:DataGridTextColumn Binding=”{Binding Font.Name}” IsReadOnly=”True” Header=”Font”> <dg:DataGridTextColumn.ElementStyle> <Style TargetType=”TextBlock”> <Setter Property=”FontFamily” Value=”{Binding Font.Name}” /> </Style> </dg:DataGridTextColumn.ElementStyle> </dg:DataGridTextColumn> And I don’t need to worry about the column inheriting the DataContext. This gives me … Read more
You don’t actually interact directly with the scrollbar, rather you set the FirstDisplayedScrollingRowIndex. So before it reloads, capture that index, once it’s reloaded, reset it to that index. EDIT: Good point in the comment. If you’re using a DataGridView then this will work. If you’re using the old DataGrid then the easiest way to do … Read more
Here is a working code. The key point here was to use SelectedValueBinding instead of SelecteItemBinding. <DataGridComboBoxColumn Header=”Title” SelectedValueBinding=”{Binding TitleId}” SelectedValuePath=”TitleId” DisplayMemberPath=”TitleText” > <DataGridComboBoxColumn.ElementStyle> <Style TargetType=”ComboBox”> <Setter Property=”ItemsSource” Value=”{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=DataContext.Titles}”/> </Style> </DataGridComboBoxColumn.ElementStyle> <DataGridComboBoxColumn.EditingElementStyle> <Style TargetType=”ComboBox”> <Setter Property=”ItemsSource” Value=”{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}, Path=DataContext.Titles}”/> </Style> </DataGridComboBoxColumn.EditingElementStyle> </DataGridComboBoxColumn>
Complete solution of this issue at MSDN: Vertical alignment of DataGrid row content. In brief, in style-file set: <!–body content datagrid cell vertical centering–> <Style x:Key=”Body_Content_DataGrid_Centering” TargetType=”{x:Type DataGridCell}”> <Setter Property=”Template”> <Setter.Value> <ControlTemplate TargetType=”{x:Type DataGridCell}”> <Grid Background=”{TemplateBinding Background}”> <ContentPresenter VerticalAlignment=”Center” /> </Grid> </ControlTemplate> </Setter.Value> </Setter> </Style> In window file: <DataGrid x:Name=”ContentDataGrid” Style=”{StaticResource ContentDataGrid}” CellStyle=”{StaticResource Body_Content_DataGrid_Centering}” ItemsSource=”{Binding}” … Read more
Try use DataGridTemplateColumn. I created sample test class for databinding public class Test { public Test(string name, string attribute1, string attribute2) { Name = name; Attributes = new Attribute(attribute1, attribute2); } public string Name { get; set; } public Attribute Attributes { get; set; } } public class Attribute { public Attribute(string attribute1, string attribute2) … Read more
Basically your button will inherit the datacontext of a row data object. I am calling it as MyObject and hope MyObject.ID is what you wanted. private void Button_Click(object sender, RoutedEventArgs e) { MyObject obj = ((FrameworkElement)sender).DataContext as MyObject; //Do whatever you wanted to do with MyObject.ID }
Don`t forget to use DataGrid.Columns, all columns must be inside that collection. In my project I format date a little bit differently: <tk:DataGrid> <tk:DataGrid.Columns> <tk:DataGridTextColumn Binding=”{Binding StartDate, StringFormat=\{0:dd.MM.yy HH:mm:ss\}}” /> </tk:DataGrid.Columns> </tk:DataGrid> With AutoGenerateColumns you won`t be able to contol formatting as DataGird will add its own columns.
There is DataTable class in .Net. Its primary purpose is to communicate with relational database but it can be used nicely to store, display and edit tabular data (e.g. read and display .csv/Excel files -> DataTable + DataGrid in wpf, DataTable + DataGridView in WinForms). DataTable columns (DataColumn) can be added/removed at runtime and DataGrid … Read more
