如何基于上一个窗口按钮显示网格单击WPF c＃

Question

I have a button button UpdatePatient on the window MainMenuWindow . What I want the button to do is display the PatientMainWindow as well as the grid on the PatientMainWindow and change the label content to Update Patient .

private void button_updatePatient_Click(object sender, RoutedEventArgs e)
{
        gridHidden_True();
        PatientMainWindow patientMainWindow = new PatientMainWindow();
        patientMainWindow.ShowDialog();
        patientMainWindow.Grid_SelectPatient.Visibility = Visibility.Visible;
        patientMainWindow.label_PatientWindowType.Content = "Update Patient";
        this.Close();
}

gridHidden_True() is just a method that I have that hides grids on the current window.

When the new window displays the label content does not change and the grid is not set to visible.

You are displaying modal window first and only then setting properties (after window is closed). You should set them first:

var patientMainWindow = new PatientMainWindow();
patientMainWindow.Grid_SelectPatient.Visibility = Visibility.Visible;
patientMainWindow.label_PatientWindowType.Content = "Update Patient";    
patientMainWindow.ShowDialog();
