How would i move a dynamically added text box after the program has started?
I would like the person that uses the program to be able to move it.
and here is the code that i'm using to put in a text box.

C#

private void button1_Click(object sender, System.EventArgs e)
{
    TextBox textbox1 = new TextBox();
    textbox1.Location = new Point(25, 25);
    this.Controls.Add(textbox1);
}

p.s. will the code above give me infinite amounts of text boxes because that's kinda what i want.

sorry to SA for not wording the question right.

Why do you think a text box could be created "before runtime"?

Modify you button click Event as below

C#

TextBox textbox1 = new TextBox();
textbox1.Name = "Txt1";// this is useful to identify the object
textbox1.Location = new Point(25, 25);
this.Controls.Add(textbox1);

Then add this code to where you want to move the text box

C#

foreach (Control item in this.Controls)
{
    if (item is TextBox && item.Name == "Txt1")
        item.Location = new Point(90, 90);//this is the x,y coordination to new location
}

Solution 1

You move it in exact same way: myTextBox.Location = new Point(/* .. */); or myTextBox.Left = /* ... */; myTextBox.Top = /* ... */. No invalidation is required, as it is all implemented in the property setters.

You understanding or design time is wrong: all controls are created during run-time. The designer is something working in the Visual Studio design time; it only helps to write code which actually is executed during your application's run-time. To make sure, just take a look at the auto-generated C# code. By the way, this is also a simple way of learning how to write some code if you only know how to do it with the designer: look at the auto-generated file and see.

i think the problem is he can't access the object from outside the button click event because it is local to that block.

Thank you for this note.

Of course, there would be no direct access to it; the problems is that the code is weird: it will add a control in the same location, on every click. Probably OP needs the closure; with output position parameter shifting on every click. As I don't see much sense in it, I don't want to get into further detail; maybe OP will ask me.
