c# - WPF checkbox twoway binding from property to UI is not working on propertychanged event -

I am using twoway binding in the checkbox data column in the Taylor Grid view control. When I change the status of the checkbox on the UI, this asset is working fine to trigger the changed event. But on the contrary, on changing the property value behind the code, the checkbox state should also be updated on the UI.

  & lt; Button x: name = "btn1" Grid.Row = "0" content = "Refresh" Click = "BTN 1_Click" width = "100" margin = "0,5" /> & Lt; Telerik: RadGridView grid. Line = "1" x: name = "gridview" ShowGroupPanel = "False" isFiltering permission = "incorrect" selectionMode = "multiple" & gt; & Lt; Telerik: RadGridView.Columns & gt; & Lt; TeleReak: GridViewdata column width = "70" header = "color" & gt; & Lt; Telerik: GridViewDataColumn.CellTemplate & gt; & Lt; DataTemplate & gt; & Lt; StackPanel Orientation = "Horizontal" & gt; & Lt; Check box IsChecked = "{Binding ChangeValue, Mode = TwoWay}" margin = "3" /> & Lt; / StackPanel & gt; & Lt; / DataTemplate & gt; & Lt; / Telerik: GridViewDataColumn.CellTemplate & gt; & Lt; / Telerik: GridViewDataColumn & gt; & Lt; Telerich: GridVidata column header = "data" datamaberbing = "{binding datawall}" IsReadOnly = "True" /> & Lt; / Telerik: RadGridView.Columns & gt; & Lt; / Telerik: RadGridView & gt; & Lt; / Grid & gt;  

Backing code

  Public partial square main window: window {list & lt; Data & gt; DataSource = New list & lt; Data & gt; (); Public Manvindo () {Initialization (); For (int i = 0; i  

riff Resh button'm clicking I want to go unchecked the box but they are not updated when I incorrectly set PopulateGridView the ChangeValue on. Please do could suggest how I get it.

you'll need to specify that when UI shawls update Case onpropertychanged

  & Lt; check box ischhecked = "{binding change value, mode = dow, updated source = catalyst =" property Central turned "}" Margin = "3" / & gt;
