How can I dynamically change the text of many textboxes?-CodePudding

This is a piece of the code i have done but i want to make it shorter.

textBox0.Text = array[0];
textBox1.Text = array[1];
textBox2.Text = array[2];
textBox3.Text = array[3];
textBox4.Text = array[4];
....

This is how i want it :

int a = 0;
for(int N=0; N  ; N<5)
        textboxN.text = array[a];
        a  ;

If the textboxes have a common container, like a Panel or GroupBox control, you can do this:

 TextBox[] textBoxes = container.Controls.OfType<TextBox>().ToArray();

And then later:

for(int N = 0; N < array.Length; N  )
{
    textbox[N].Text = array[N];
}

Note the container can even be your form, but in this case you must make sure you don't have an other TextBox controls on the form. That's why something like a borderless panel might be useful here; it gives you a logical section on the form to keep these fields separate in a way that can be invisible to the user.

This could help you:

List<TextBox> textBoxes = new List<TextBox>() {textBox0, textBox1, textBox2, textBox3, textBox4 };
for(int i = 0; i < textBoxes.Count; i  )
{
    textBoxes[i].Text = array[i];
}

You put the text boxes into a list and then go through them and set the values. Here is that as a one-liner

textBoxes.Foreach(x => x.Text = array[textBoxes.IndexOf(x)]);

Try This

var textBoxList = new List<Control>();
foreach (var control in this.Controls)
{
    if (control.GetType().Name == "TextBox")
    {
        textBoxList.Add(control as Control);
    }
}

textBoxList = textBoxList.OrderBy(t => t.Name).ToList();
for (var i = 0; i < textBoxList.Count; i  )
{
    textBoxList[i].Text = array[i];
}

You can try something like this, but it makes some sense if you have dozens textboxes

var maxIndex=array.length;
foreach (var control in this.Controls)
{
    var textBox = control as TextBox;
    if (textBox != null)
    {
        var i=  Convert.ToInt16( textBox.Name.Substring(6));
        if ( i<maxIndex) textBox.Text=array[i];
    }
}
