Hi all,

In my WPF application, I need to get all the selected rows of a datagrid on the click of a button which is outside the datagrid.I am using a checkbox in the row header template to select or deselect a row. Below is the small code snippet of my datagrid xaml. Please can any one help me out in fetching all the selected rows on the click of a button. I have searched a lot on google, but all the links are regarding fethcing selected items on "dataGrid_SelectionChanged" event, which is very easy.

XML

<my:DataGrid AutoGenerateColumns="False" SelectionChanged="dataGrid_SelectionChanged" Initialized="DataGrid_Initialized" >

<my:DataGrid.RowHeaderTemplate>
                <DataTemplate>
                    <Grid>
                        <CheckBox IsChecked="{Binding Path=IsSelected, Mode=TwoWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type my:DataGridRow}}}"/>
                    </Grid>
                </DataTemplate>
            </my:DataGrid.RowHeaderTemplate>
 <my:DataGrid.Columns>
     <my:DataGridTemplateColumn Width="160" Header="Media Status" >
                    <my:DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                         <StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="5,8,5,0">
                                <TextBlock>
                             <TextBlock.Style>
                                <Style>
                                    <Style.Triggers>
                                        <DataTrigger Binding="{Binding MediaStatus}"  Value="False">
                                            <Setter Property="TextBlock.Text" Value="Not Processed" />
                                        </DataTrigger>
                                        <DataTrigger Binding="{Binding MediaStatus}" Value="True">
                                            <Setter Property="TextBlock.Text" Value="Processed" />
                                        </DataTrigger>
                                    </Style.Triggers>
                                </Style>
                            </TextBlock.Style>
                               </TextBlock>
                            </StackPanel>
                                                          
                        </DataTemplate>
                    </my:DataGridTemplateColumn.CellTemplate>
                </my:DataGridTemplateColumn>
            </my:DataGrid.Columns>
        </my:DataGrid>

Solution 2

A better way:

MSIL

foreach (var data in dataGridMain.SelectedItems)
{
    MyObservableCollection myData = data as MyObservableCollection;
    MessageBox.Show(myData.author);
}

Where "MyObservableCollection" is your data class that is bound to the DataGrid (in this case dataGridMain). And this collection has an author string for example.

Thanks everyone who are reading this post. I did it myself. I am posting the code below, for reference of others who need it. Please suggest if any good modification can be made to it.

C#

private void btnProcessMedia_Click(object sender, RoutedEventArgs e)
        {
                if (dgProjects.SelectedItems.Count > 0)
                {
                    for (int i = 0; i < dgProjects.SelectedItems.Count; i++)
                    {
                        System.Data.DataRowView selectedFile = (System.Data.DataRowView)dgProjects.SelectedItems[i];
                        string str = Convert.ToString(selectedFile.Row.ItemArray[10]);
                    }
                }
            
        }
