问题 I would like to know if it would be possible to add functionality to the 'Select All' button in the top left of a datagrid so that it also unselects all rows? I have a method attached to a button which does this, but it would be great if I could fire this method from the Select All button, to keep functionality in the same part of the view. Can this 'Select All' button have code added to it, and if so, how would one get to the button? I haven't been able to find any examples or suggestions.

问题 I've implemented code to get around the double click issue when selecting a row in a WPF DataGrid. I'm using the following code from here: https://stackoverflow.com/a/5857908/40106. <Style TargetType="DataGridCell"> <Style.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter Property="IsEditing" Value="True" /> </Trigger> </Style.Triggers> </Style> Rows have alternating colors.

问题 I have a converter that takes the text from a TextBlock that makes up a DataGridCell and converts it to a red or black brush depending if the value is negative or positive. However the converter executes more times than there are items in the datasource of the grid. For example if I simply bind a collection that contains 1 object, the converter executes 2 times. The first time the value parameter is an empty string, the second time it actually contains the value that I would expect. If I add

问题 I have a DataGrid and I'm trying to do the Sort thing the most straightforward way: by clicking on the header of each column. This is working great on the View ( in the MVVM context ), but I want to sort the underlying ViewModel collection ( ObservableCollection ) too. Any suggestions on how to implement the source collection? 回答1: Bind the grid to a ListCollectionView , initialised with the ObservableCollection . The grid will use your pre-created ICollectionView instead of creating it's own
