问题 I've got two WPF Toolkit DataGrids , I'd like so that when the user resizes the first column in the first grid, it resizes the first column in the second grid. I've tried binding the width of the DataGridColumn in the second grid to the appropriate column in the first grid, but it doesn't work. I'd prefer to use all xaml, but I'm fine with using code behind as well. <tk:DataGrid Width="100" Height="100"> <tk:DataGrid.Columns> <tk:DataGridTextColumn x:Name="Column1" Width="50"/> </tk:DataGrid

Tag Property in WPF DataGrid Column

问题 I need to save an string inside a Datagrid Column which differs from the Header. This is needed because I generate a Datagrid dynamically and want to translate the Column Headers while generating them. Then I bind the whole XAML to a ContentControl. No problem till here... But I want to reorder and resize the columns, so I need to lookup them afterwoods. For this I need the original (not translated) ColumnHeader. In my opinion a Tag property of the column would solve this problem, but there

Where am I going wrong? 回答1: The Header object of the DataGridColumn is actually the visible header of that column, whatever you set it to be.

Wpf DataGrid Column splitting

由 戏子无情 提交于 2019-12-14 03:59:52
问题 I want to put a column to specify range in a wpf datagrid. For this, i am thinking to take one column with header "Range" and i want to split that into 2 columns like "Minimum" and "Maximum". Is it possible to represent data like that? If it is, what about the data binding to the datagrid means how binding will change? 回答1: If you can keep you min/max parts non-resizable, then a fairly simple solution exists: In your objects create a property of Tuple type or whatever type will represent your

WPF - DataGrid Column with Width=“*”, but MinWidth to Fit Contents

由 时光怂恿深爱的人放手 提交于 2019-11-28 08:04:20
What would be the best/right way to have a set of DataGrid columns have proportional width ( Width="\*"), but to have their minimum width be at least the width of their content? At the moment, if I use Width="*" , then the columns stay exactly proportional, but content gets cropped if the columns get too thin. If I use Width="Auto" , then the columns size themselves perfectly to their content, but this makes them all different sizes. What I want is really a combination of the two, like Width="\*" , MinWidth="Auto" so that when there's extra width the columns will all space out to equal widths,
