Hi,

I am using Xceed DataGrid for WPF binding it with an observable collection. I have around 20 columns and i am looking to set the individual cell (not whole column) enable/disable as per my business logic.

I tried setting the same from corresponding .xaml.cs file using:

"((DataRow)dataGrid.GetContainerFromItem(anItem)).Cells[someCell].IsEnabled = false;"

However the setting is not preserved after scrolling or some other rendering. To solve this I decided to go with DataTrigger. Currently i am using one extra property per original property in my class. For example, if there is a column "Name" i am keeping one extra property as "Name_Enabled" to keep the enable/disable information of "Name" property. I am using this "Name_Enabled" property in data trigger to set the "IsEnabled" property of "Name" accordingly. So now i am having 40 columns instead of 20 :(

Is there any better way to acheive this?

Please help!

Hi,

The ideal method is to use an implicit Style on DataCell with a DataTrigger in which you can set the “IsEnabled” property.

For example:

<Style TargetType="xcdg:DataCell">

                <Style.Triggers>

                    <DataTrigger Binding="{Binding Path=DataContext[Name_Enabled],RelativeSource={RelativeSource Self}}"

                                 Value="True">

                        <Setter Property="IsEnabled"

                                Value="True" />

                    </DataTrigger>            

                </Style.Triggers>

            </Style>

same case here:

I would have thought that below should have worked

"((DataRow)dataGrid.GetContainerFromItem(anItem)).Cells[someCell].IsEnabled = false;"

However the setting is not preserved after scrolling or some other rendering.

can any body suggest on what is going wrong here and any workaround.
