Hi there,

 i have a small project with a DataGrid where one field is a CheckBoxColumn.

 i set the CheckBox in the Column with the following Style in code behind:

 

UnboundField checkfield = new UnboundField();

ControlTemplate controltemplate;
string xamlControl = "";

xamlControl = @"
<ControlTemplate xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml"" xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"">
<CheckBox HorizontalAlignment=""Center"" IsChecked=""{Binding Attributes[Used]}"" VerticalAlignment=""Center""/>
</ControlTemplate>"; 

 

byte[] xmlControl = Encoding.ASCII.GetBytes(xamlControl);
MemoryStream stream = new MemoryStream(xmlControl);

controltemplate = (ControlTemplate)XamlReader.Load(stream);

Setter templateSetter = new Setter(CellValuePresenter.TemplateProperty, controltemplate);

Style checkboxcell = new Style(typeof(CellValuePresenter));
checkboxcell.Setters.Add(templateSetter);

checkfield.Settings.CellValuePresenterStyle = checkboxcell;

i tried another way:

UnboundField checkfield = new UnboundField();

checkfield.Name = "";
checkfield.Settings.EditorType = typeof(XamCheckEditor);
checkfield.Settings.EditAsType = typeof(bool);

Style editorStyle = new Style(typeof(XamCheckEditor));

Setter styleSetter = new Setter(XamCheckEditor.IsCheckedProperty, dictionary["Used"]);
editorStyle.Setters.Add(styleSetter);
checkfield.Settings.EditorStyle = editorStyle;
checkfield.Settings.AllowEdit = true;
checkfield.Width = new FieldLength(50);
grid.FieldLayouts[0].Fields.Add(checkfield); 

 this works as good as the other way. But now i have the problem that if i want to get the Value of the cell where my checkbox is in, the value is null.

i noticed that i have to edit one time so that the value of the cell is filled with true or false. but i need that the value is loaded at the first loading of the window.

please help me asap
