Question

I have a form in which there are many textboxes (in tabControl layout). I am disabling right click function on all the textboxes. by giving the below code:

        txtAmountChildPlans.ContextMenu = new ContextMenu();
        txtCityHome.ContextMenu = new ContextMenu();
        txtCityPersonal.ContextMenu = new ContextMenu();
        txtCityRetirement.ContextMenu = new ContextMenu();
        txtEmailCar.ContextMenu = new ContextMenu();
        txtEmailCarIns.ContextMenu = new ContextMenu();
        txtEmailHome.ContextMenu = new ContextMenu();
        txtEmailOp.ContextMenu = new ContextMenu();
        txtEmailPersonal.ContextMenu = new ContextMenu();
        txtEmailSenior.ContextMenu = new ContextMenu();
        txtEmailTwoIns.ContextMenu = new ContextMenu();
        txtFullNamePersonal.ContextMenu = new ContextMenu();
        txtManufacturerCar.ContextMenu = new ContextMenu();
        txtMobileCar.ContextMenu = new ContextMenu();
        txtMobileCarIns.ContextMenu = new ContextMenu();
        txtMobileHome.ContextMenu = new ContextMenu();
        txtMobileNoRetirement.ContextMenu = new ContextMenu();
        txtMobileOp.ContextMenu = new ContextMenu();
        txtMobilePersonal.ContextMenu = new ContextMenu();
        txtMobileSenior.ContextMenu = new ContextMenu();
        txtMobileTwoIns.ContextMenu = new ContextMenu();
        txtModelCar.ContextMenu = new ContextMenu();
        txtMonthlySalaryCar.ContextMenu = new ContextMenu();
        txtNameHome.ContextMenu = new ContextMenu();
        txtNameRetirement.ContextMenu = new ContextMenu();
        txtPensionRetirement.ContextMenu = new ContextMenu();
        txtRegCarIns.ContextMenu = new ContextMenu();
        txtRegTwoIns.ContextMenu = new ContextMenu();

EDIT:

        foreach (var textbox in this.Controls.OfType<TextBox>())
        {
            textbox.ContextMenu = new ContextMenu();
        }
        foreach (var textbox in this.tabCarInsurance.Controls.OfType<TextBox>())
        {
            textbox.ContextMenu = new ContextMenu();
        }
        foreach (var textbox in this.tabHealth.Controls.OfType<TextBox>())
        {
            textbox.ContextMenu = new ContextMenu();
        }
        foreach (var textbox in this.tabHomeLoans.Controls.OfType<TextBox>())
        {
            textbox.ContextMenu = new ContextMenu();
        }
        foreach (var textbox in this.tabRetirement.Controls.OfType<TextBox>())
        {
            textbox.ContextMenu = new ContextMenu();
        }

Is there anyway to write this in sigle function. or less code?

This doesnt look good to me. Is there any way in c# like in css to give the same property to all the textboxes?

Answer 1

You can enumerate throuh all textboxes and create new context menu in loop

foreach (TextBox textbox in AllTextBoxes(this))
{
    textbox.ContextMenu = new ContextMenu();
}

public IEnumerable<TextBox> AllTextBoxes(Control control)
{
    List<TextBox> result = new List<TextBox>();
    result.AddRange(control.Controls.OfType<TextBox>());
    foreach (var childControl in control.Controls.OfType<Control>())
    {
        result.AddRange(AllTextBoxes(childControl));
    }
    return result;
}
