Hi
I'm new to WPF can anyone explain me how to select a DataGrid Table Row and delete it in a button click using WPFin MVVM modal.


I can remove the row by button click, only by hard coding the value.

HostSystemInformation info = (from sysinfo in systemInformation
                                    where sysinfo.Sno == 4
                                    select sysinfo).First();

From above code i can delete only 4th row. I want solution to GET VALUE IN A VARIABLE WHEN I SELECT A ROW in datagrid table. I want to use that variable instead of hardcoded value 4. This coding not done in code-behind, done in seperate ModalView file

I have copied my code below someone give a solution for this.

XAML:

<Button Content="Remove" Command="{Binding DeleteIp}" Grid.Row="0" Grid.Column="1" FontFamily="Ebrima" FontSize="12" Width="61" Height="25" HorizontalAlignment="right" VerticalAlignment="center"/>
<DataGrid  Name="datagridIpTable"  ItemsSource="{Binding SystemInformation}"  SelectedItem="{Binding Path=SelectedCustomer, Mode=TwoWay}" AutoGenerateColumns="false"  Grid.Row="1" Grid.Column="1" CanUserAddRows="False" >
    <DataGrid.Columns >
        <DataGridTextColumn Binding="{Binding Sno}"  Header="S.No" MinWidth="50" />
        <DataGridTextColumn Binding="{Binding strIpAddr}" Header="System Name" MinWidth="240"/>
        <DataGridTextColumn Binding="{Binding strSystemName}" Header="IP Address" MinWidth="240"/>
        <DataGridTextColumn Binding="{Binding strStatus}" Header="Status" MinWidth="140" />
    </DataGrid.Columns>
</DataGrid>

rivate DelegateCommand deleteIp;

public DelegateCommand DeleteIp
{
    get { return deleteIp; }
    set { deleteIp = value; }
}

private ObservableCollection<HostSystemInformation> systemInformation;

public ObservableCollection<HostSystemInformation> SystemInformation
{
    get { return systemInformation; }
    set { SetProperty(ref systemInformation, value); }
}

public UserBase_ViewModal()
{
    SystemInformation = new ObservableCollection<HostSystemInformation>();
    deleteIp = new DelegateCommand(DeleteSystemInformationInIpTable);
}

private void DeleteSystemInformationInIpTable()
{
    try
    {        
        if(systemInformation.Count>0)
        {
            int count=0;
            foreach (object eno in systemInformation)
            {
                HostSystemInformation info = (from sysinfo in systemInformation
                                     where sysinfo.Sno == 4 
                                     select sysinfo).First(); /*Here instead of 4th row i need to pass variable dynamically by pressing any row */
                systemInformation.Remove(info);
                count++;
            }
        }
    }
    catch (Exception ex)
    {
        // MessageBox.Show(ex.Message);
    }
}

public class HostSystemInformation
{
    public int Sno { get; set; }
    public string strIpAddr { get; set; }
    public string strSystemName { get; set; }
    public string strStatus { get; set; }
}

Thanks in Advance...
