Edit: Updated to reflect the input of Aran Mulholland (see comment) Apparently the DataGrid is passing the entire DataRowView to each cell. That’s why the binding doesn’t work. Your DataTemplate expects the DataContext to be of type MyData, but instead it is of type DataRowView. My proposed (somewhat hack-ish) workaround to get the DataContext you … Read more
To find a control in a DataGrid template column, you should use FindChild(): public static T FindChild<T>(DependencyObject parent, string childName) where T : DependencyObject { if (parent == null) { return null; } T foundChild = null; int childrenCount = VisualTreeHelper.GetChildrenCount(parent); for (int i = 0; i < childrenCount; i++) { var child = VisualTreeHelper.GetChild(parent, … Read more
Please refer to the DataGrid Class page on MSDN. From that page: Selection By default, the entire row is selected when a user clicks a cell in a DataGrid, and a user can select multiple rows. You can set the SelectionMode property to specify whether a user can select cells, full rows, or both. Set … Read more
A column in a datagrid is an abstract object which does not appear in the visual tree, thus you cannot use RelativeSource-binding, ElementName will not work either since it will not find a governing FrameworkContentElement so you are in kind of a bind. One way that works is via Source and x:Reference, for that you … Read more
The DataGrid will increase column sizes to fit as the data becomes longer, but it does not automatically decrease column sizes when the length of the data decreases. In your example, you’re right aligning the ‘Change’ column, and using the rest of the space for the ‘Name’ column. Now, when a ‘Change’ property grows large … Read more
There are a few options you can turn on to help you on your DataGrid object EnableColumnVirtualization = true EnableRowVirtualization = true These two are the main ones I think might help. Next try making your binding async ItemsSource=”{Binding MyStuff, IsAsync=True}” And lastly, I’ve heard that setting a maximum height and width can help even … Read more
first of all, DataGrid generate DataGridTextColumns by default and we have to use AutoGeneratingColumn event to change type of column. We need to use DataGridTemplateColumn which contains Image in template (image source should be bound to correct DataTable column). The best place to define template is in Resources. here is how the issue can be … Read more
People seem to be overcomplicating this, this worked for me: foreach (System.Data.DataRowView dr in yourDataGrid.ItemsSource) { MessageBox.Show(dr[0].ToString()); }
The above solution left blue border around each cell in my case. This is the solution that worked for me. It is very simple, just add this to your DataGrid. You can change it from a SolidColorBrush to any other brush such as linear gradient. <DataGrid.Resources> <SolidColorBrush x:Key=”{x:Static SystemColors.HighlightBrushKey}” Color=”#FF0000″/> </DataGrid.Resources>
UPDATED To get the selected rows try: IList rows = dg.SelectedItems; You should then be able to get to the column value from a row item. OR DataRowView row = (DataRowView)dg.SelectedItems[0]; Then: row[“ColumnName”];
