WPF DataGrid Control Select All Option

Question

<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="5" />               
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>   
<DataGrid x:Name="DtgEntity" Grid.Row="0" ItemsSource="{Binding Entities, Mode=TwoWay}" AutoGenerateColumns="False" ></DataGrid>
<GroupBox Header="Selected Entities" Grid.Row="2" >
<DataGrid x:Name="DtgSelectedEntity" ItemsSource="{Binding SelectedEntities, Mode=TwoWay}" ></DataGrid>
</GroupBox>
</Grid>

This is my grid control code. Column Name, Number of columns are changed based on object type. So here i can't specify the grid columns tag. But first column of the grid always check box.

How can i change the first column header as check box. I want to implement select all option for first column of the grid.

Implement first column is checkbox column and implement select all is quite easy. But each case have it own way. If you can explain more clear, include full XAML code of your DataGrid, I can help you. — NoName, Mar 01 '16 at 04:44
I added my full XAML code. Data grid columns count are not fixed. Column count and names changed based on user selection. But first columns must be check box. After select one item its moved to second grid. Single selection working fine. But i need to implement select all option. — Siva G, Mar 01 '16 at 05:02
your Datagrid bind to a collection contains many type of object or to many collection, each contains one type of object? And does the Property you bind to first column have same name and type? — NoName, Mar 01 '16 at 05:44
Okay. Seem to delicate if I ask you unveil more. So, just use DataGridCheckBoxColumn, change header template, bind to checkAll_Property. Easily! — NoName, Mar 01 '16 at 06:16

Why not? you can specify Columns tag with a DataGridCheckBoxColumn and have AutoGenerateColumns set to true to generate columns based on object type. That will mean that a checkbox column will always apear and the rest of the columns will be generated by the binded ItemsSource type

<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="5" />               
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>   
<DataGrid x:Name="DtgEntity" Grid.Row="0" ItemsSource="{Binding Entities, Mode=TwoWay}" AutoGenerateColumns="False" ></DataGrid>
<GroupBox Header="Selected Entities" Grid.Row="2" >
<DataGrid x:Name="DtgSelectedEntity" ItemsSource="{Binding SelectedEntities, Mode=TwoWay}" AutoGenerateColumns="True" >
    <DataGrid.Columns>
         <DataGridCheckBoxColumn x:Name="myCheckBoxColumn"/>
    </DataGrid.Columns>
</DataGrid>
</GroupBox>
</Grid>

You can also set the FrozenColumnCount property of the DataGrid to 1 to make that column permamnent to scrolling.

As for the select all feature, there are plenty of threads on SO that covers this issue. here's a few:
