I am new to WPF and in my application I want to insert an image in the one of the columns header with the header text and want to write code on the image OnClick event.

Currently all the column and row data is fetched from database.

C#

newRow = dataInfo.ProcessDataRow(filter, ProcessNames[j], ProcessCaseNames[i]);

  if (newRow != null)
                            {
                                App.Current.Dispatcher.Invoke((Action)(() =>
                                    {
                                        ReportData.Add(newRow);
                                    }));
                            }

xaml code:

C#

<DataGrid ItemsSource="{Binding Path=ReportData, Mode=TwoWay}" SelectedItem="{Binding SelectedRow}" AutoGenerateColumns="True" Grid.Row="1" HorizontalAlignment="Stretch" Name="Datagrid" VerticalAlignment="Stretch" BorderThickness="1" IsReadOnly="True" AlternatingRowremoved="Gainsboro" AlternationCount="2" CanUserReorderColumns="True" BorderBrush="Black" Margin="0,3,0,90" SelectionChanged="Datagrid_SelectionChanged">

Can anyone please assist me how to implement this functionality from code behind.

I wanted something like below (Image Button Click)

C#

<window.resources>
     <style targettype="{x:Type DataGridColumnHeader}" x:key="imageDataGridRowHeader" xmlns:x="#unknown">
         <setter property="Template">
             <setter.value>
                 <controltemplate targettype="{x:Type DataGridColumnHeader}">
                     <stackpanel orientation="Horizontal">
                         <textblock text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}, Path=Columns[1].Header}" />

                     <Button x:Name="btnFilter" Margin="3,0,0,0" Content="Content_1">
                         <Button.Template>
                             <controltemplate>
                                 <image ishittestvisible="True" height="10" width="10" verticalalignment="Center" source="/..Image.png" margin="0" keyboardnavigation.istabstop="False" />
                             </controltemplate>
                         </Button.Template>
                     </Button>
                     </stackpanel>
                 </controltemplate>
             </setter.value>
         </setter>
     </style>
 </window.resources>
 <grid></grid>

and in .xaml.cs to have Click event I added below:

C#

void data1_AutoGeneratingColumn(object sender ,DataGridAutoGeneratingColumnEventArgs e)
 { 
             e.Column.HeaderStyle = FindResource("imageDataGridRow <big> Header")as Style;
 EventManager.RegisterClassHandler(typeof(Button), Button.ClickEvent, new RoutedEventHandle</big>r(btn_Click));

}

You can simple Create one Header style in which u can take one stackpanel which will contain one textblock and one image with appropriate path and add that header style to runtime to that control

XAML Code

HTML

<Window x:Class="PrintingApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Window.Resources>
        <Style TargetType="{x:Type DataGridColumnHeader}" x:Key="imageDataGridRowHeader">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type DataGridColumnHeader}">
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}, Path=Columns[1].Header}"/>
                            <Image IsHitTestVisible="True" Height="20" Width="20" VerticalAlignment="Center"  Source="/PrintingApplication;Component/dark_windows_8-wide.jpg"  Margin="0" KeyboardNavigation.IsTabStop="False"/>
                        </StackPanel>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    <Grid >
        <DataGrid x:Name="data1" AutoGenerateColumns="True"  ItemsSource="{Binding Path=.}"  Width="500" Height="500" PreviewMouseRightButtonDown="data1_PreviewMouseRightButtonDown_1"></DataGrid>
    </Grid>
</Window>

Code Behind Call

C#

public MainWindow()
       {
           InitializeComponent();
           BindDataToDataGrid();
       }


       private void BindDataToDataGrid()
       {
           DataTable dt = new DataTable();
           dt.Columns.Add("ID");
           dt.Columns.Add("Image");
           dt.Rows.Add("Kartik", "Send");
           dt.Rows.Add("Ashok", "Resend");
           dt.Rows.Add("Paresh", "Report");
           dt.AcceptChanges();

           data1.ItemsSource = dt.DefaultView;

           data1.AutoGeneratingColumn += data1_AutoGeneratingColumn;
       }

       void data1_AutoGeneratingColumn(object sender, DataGridAutoGeneratingColumnEventArgs e)
       {
           if (Convert.ToString(e.Column.Header) =="Image")
           {
               e.Column.HeaderStyle = FindResource("imageDataGridRowHeader") as Style;
           }
       }
