in C#, Winforms. I have a very wide form/panel, around 40,000 pixels wide. When i programatically add TextBoxes, and specify a textbox.Left > about 32767, the TextBoxes all stop at around a Left of 32767. The Microsoft Docs say the Conrol.Left property is Int32, but it is acting like it is Int16. I get no error, it just sticks all the TextBoxes around the 32767 Left point. Is this a limitation that can't be exceeded? thanks...
I've tried with a Panel, and directly on a Form, same result. see code.
namespace testTextBoxLeftPosition { public partial class Form1 : Form { public Form1() { InitializeComponent(); this.AutoScroll = true; //add scrollbars to Form1 }
private Int32 TBWidth = 100;
private Int32 TBLeft;
private Int32 TBTop;
private void button1_Click(object sender, EventArgs e)
{
TBTop = 100;
TBLeft = 50;
TextBox tb1 = new TextBox();
tb1.Width = TBWidth;
tb1.Location = new Point(TBLeft, TBTop);
tb1.Text = "tb1";
this.Controls.Add(tb1);
TBTop = 150;
TBLeft = 32600;
TextBox tb2 = new TextBox();
tb2.Width = TBWidth;
tb2.Location = new Point(TBLeft, TBTop);
tb2.Text = "tb2";
this.Controls.Add(tb2);
TBTop = 200;
TBLeft = 32700;
TextBox tb3 = new TextBox();
tb3.Width = TBWidth;
tb3.Location = new Point(TBLeft, TBTop);
tb3.Text = "tb3";
this.Controls.Add(tb3);
TBTop = 250;
TBLeft = 32800;
TextBox tb4 = new TextBox();
tb4.Width = TBWidth;
tb4.Location = new Point(TBLeft, TBTop);
tb4.Text = "tb4";
this.Controls.Add(tb4);
TBTop = 300;
TBLeft = 32900;
//TextBox tb5 = new TextBox();
//tb5.Width = TBWidth;
//tb5.Location = new Point(TBLeft, TBTop);
//tb5.Text = "tb5";
//this.Controls.Add(tb5);
}
private void button2_Click(object sender, EventArgs e)
{
TBTop = 300;
TBLeft = 32900;
TextBox tb5 = new TextBox();
tb5.Width = TBWidth;
tb5.Location = new Point(TBLeft, TBTop);
tb5.Text = "tb5";
this.Controls.Add(tb5);
}
}
}
what is also odd, is that if i uncomment the tb5 textbox, it seems to change the location of textboxes 2 thru 4.
