WPF, count number of empty textbox and ComboBox

Xiaoliang Ma

I have a C# WPF application with 400+ textbox and combo box. I need to count number of empty or null textbox and combo box. i have below code to count. but the problem is i have 400+ tests. It doesnt look like "smart" code if I follow the same way to count 400+ textboxes. Is there a better way to handle this case? Any help are much appreciated

int i = 0;

if (!String.IsEmptyorNull(txtBox1.Text))

{

i++;

}

else

{

if (!String.IsNullOrEmpty(txtBox2.Text))

i++;

}

txtTotal = i.ToString();

If your control are in a Grid or some panel, you can loop through each of the control and find them
foreach(control c in grid.children)
{
   switch (control.GetType().Name)
   {
       case "TextBox":
       TextBox text = (TextBox)control;
       if(string.IsNullOrWhiteSpace(text.Text))
       {
            //increment
       }
   }
}
