Set focus on textbox in WPF from view model (C#) & wPF
- by priyanka.sarkar
I have a TextBox and a Button in my view.
Now I am checking a condition upon button click and if the condition turns out to be false, displaying the message to the user, and then I have to set the cursor to the text box control.
if (companyref == null)
{
Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation cs = new Lipper.Nelson.AdminClient.Main.Views.ContactPanels.CompanyAssociation();
MessageBox.Show("Company does not exist.", "Error", MessageBoxButton.OK,
MessageBoxImage.Exclamation);
cs.txtCompanyID.Focusable = true;
System.Windows.Input.Keyboard.Focus(cs.txtCompanyID);
}
The above code is in the view model.
The CompanyAssociation is the view name.
But the cursor is not getting set in the TextBox.
The xaml is as under
<igEditors:XamTextEditor KeyDown="xamTextEditorAllowOnlyNumeric_KeyDown"
Name="txtCompanyID" ValueChanged="txtCompanyID_ValueChanged" Text="{Binding
Company.CompanyId, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" Width="{Binding
ActualWidth, ElementName=border}" Grid.Column="1" Grid.Row="0"
VerticalAlignment="Top" Margin="0,5,0,0" HorizontalAlignment="Stretch"
IsEnabled="{Binding Path=IsEditable}" />
<Button Template="{StaticResource buttonTemp1}" Command="{Binding ContactCommand}"
CommandParameter="searchCompany" Content="Search" Width="80" Grid.Column="2"
Grid.Row="0" VerticalAlignment="Top" Margin="0" HorizontalAlignment="Left"
IsEnabled="{Binding Path=IsEditable}" />
Please help
