I am making a programme with which I want to start Windows services. I search all services for a name (for example "VMware") and write them in a list. Now I want to start a service. I then get the error message "The object of type "WpfApp1.myService" cannot be converted to type "System.Data.DataRowView"."

When I start all services it works. Here is my code (XAML):

<Window x:Class="WpfApp1.MainWindow"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:local="clr-namespace:WpfApp1"

        <DataGrid.Columns>

            <DataGridTextColumn Header="Product" Binding="{Binding Path='Product'}" IsReadOnly="True" />
            <DataGridTextColumn Header="Category" Binding="{Binding Path='Category'}" IsReadOnly="True" />
            <DataGridTextColumn Header="Price" Binding="{Binding Path='Price'}" IsReadOnly="True" />
            <DataGridTemplateColumn Header="start">
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <Button Name="btnStart" Content="start" Click="btnStrt_Click" />
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>
    </DataGrid>
    <Button Content="start all services" Click="Button_Click"/>
</StackPanel>

Thanks for your help!

CodePudding user response：

I solved it like this:

<Button Name="btnStart" Content="Starten" CommandParameter="{Binding Path='Dienstname'}" Click="btnStarten_Click" />

and in the CS:

object Row_Anzeigename = ((Button)sender).CommandParameter;
string meineServices = Row_Anzeigename.ToString();

Thank you for pushing me in the right direction.
