See more:

Need to create a data grid with configurable columns. In that the cell colors will change according to the data bind.

This can be done by data trigger of that column(xaml) - 'only the cell background color'.

But i need to generate the dynamic column from view model class(mvvm wpf). And need to generate data triggers for the corresponding columns.

I have spent lots of day on googling but the end result is null.

Hi.this doesn't work completely. if you complete it, please tell me:

XML

<Style x:Key="myStyle" TargetType="{x:Type DataGridCell}">

           <Setter Property="Template">
               <Setter.Value>
                   <ControlTemplate TargetType="{x:Type DataGridCell}">

Hi. try this way :

XML

<DataGridTextColumn Header="Subject" >
                    <DataGridTextColumn.ElementStyle>
                        <Style TargetType="{x:Type TextBox}">
                            <Setter Property="Template">
                                <Setter.Value>
                                    <ControlTemplate TargetType="{x:Type TextBox}">
                                        <TextBlock Text="{TemplateBinding Text}"/>
                                    </ControlTemplate>
                                </Setter.Value>
                            </Setter>
                            <Style.Triggers>
                                <DataTrigger Binding="{Binding YourFavoriteProperty}" Value="">
                                    <Setter Property="Background" Value=""/>
                                </DataTrigger>
                            </Style.Triggers>
                        </Style>
                    </DataGridTextColumn.ElementStyle>
                </DataGridTextColumn>
