You are encountering the differences between physical scrolling and logical scrolling. As you have discovered, each has its tradeoffs. Physical scrolling Physical scrolling (CanContentScroll=false) just goes by pixels, so: The viewport always represents exactly the same portion of your scroll extent, giving you a smooth scrolling experience, and but The entire contents of the DataGrid … Read more
I’m going to preface this by saying it maybe isn’t the best solution to be doing and may not work in some situations but you can give it a try and see if it will work for what you want. I just whipped this up so it may have some bugs in it. Its still … Read more
I implemented a behavior for the DataGrid based on code I found in this thread. Usage:<DataGrid local:DataGridCommitEditBehavior.CommitOnLostFocus=”True” /> Code: using System.Collections.Generic; using System.Reflection; using System.Windows; using System.Windows.Controls; using System.Windows.Controls.Primitives; using System.Windows.Input; using System.Windows.Media; /// <summary> /// Provides an ugly hack to prevent a bug in the data grid. /// https://connect.microsoft.com/VisualStudio/feedback/details/532494/wpf-datagrid-and-tabcontrol-deferrefresh-exception /// </summary> public class DataGridCommitEditBehavior … Read more
This should work. The idea is you have this attached property that you will attach to the DataGrid. In the xaml where you attach it, you’ll bind it to a property on your ViewModel. Whenever you want to programmatically assign a value to the SelectedItem, you also set a value to this property, which the … Read more
You can filter the Items in the DataGrid by binding it to an ICollectionView that supports filtering. Details here for .NET 4. The process is the same for .NET 4.5, but it seems the documentation has been lost. There’s a small mention to it here under the “Grouping, Sorting, and Filtering” heading. edit: at the … Read more
This is possible but it’s not trivial and you will likely take a performance penalty. The way SlickGrid works, it needs to be able to answer the following two questions rapidly: For a given row X, what is the top offset for that row? For a given offset Y, what row is at that offset? … Read more
you can add the event handler in the ItemContainerStyle (which is the style applied to a row) : <DataGrid … > <DataGrid.ItemContainerStyle> <Style TargetType=”DataGridRow”> <EventSetter Event=”MouseDoubleClick” Handler=”Row_DoubleClick”/> </Style> </DataGrid.ItemContainerStyle> … </DataGrid> Then, in the handler, you can check if the row is selected private void Row_DoubleClick(object sender, MouseButtonEventArgs e) { // execute some code }
if you do not expect that your list will be recreated then you can use the same approach as you’ve used for Asp.Net (instead of DataSource this property in WPF is usually named ItemsSource): this.dataGrid1.ItemsSource = list; But if you would like to replace your list with new collection instance then you should consider using … Read more
Put the DataGrid in a Grid, DockPanel, ContentControl or directly in the Window. A vertically-oriented StackPanel will give its children whatever vertical space they ask for – even if that means it is rendered out of view.
We are using .NET 4.0. We had the same problem, but after logging off the system, code used to work fine for some time. Finally we found the alternative. If you want to copy a string to the clipboard, string data = “Copy This” Till now I was using the following method Clipboard.SetText(data); It was … Read more
