Empty text field controls after data is inserted / saved / presented in winform c # application

Question

I need to clear all textbox controls after clicking the SAVE button, but the user. I have about 10 of them. How to clear the text from them all at the same time. I just know about:

textbox1.Text="";

But, if I do this, then I need to repeat this for no. text box controls in my form, will it be a labor task instead of a programmer?

Please guide.

Answer 1

try it

foreach(TextBox textbox in this.Controls.OfType<TextBox>())
{
   textbox.Text = string.Empty;
}

If you want to clear all text fields recursively, use this function.

void ClearTextBoxes(Control control)
{
    foreach(Control childControl in control.Controls)
    {
         TextBox textbox = childControl as TextBox;
         if(textbox != null)
            textbox.Text = string.Empty;
         else if(childControl.Controls.Count > 0)
             ClearTextBoxes(childControl);
    }
}
