Hello, Sorry for delayed answer. ScrollingPosition property gets the current position of the scroll bar. When you change width and height of the workspace, scroll bar is shown, but it has ScrollingPosition.X = 0, and ScrollingPosition.Y = 0 (the start coordinates (0; 0)). If you need to check whether scroll bar is visible, you can change its horizontal or vertical position a bit. Then ScrollingPosition.X will not be equal to zero.

Hello, Here is code snippet shows how to change position of scroll bar: Code:
private void textBox1_TextChanged(object sender, EventArgs e)
{
try
{
multiLayerViewer1.WorkspaceWidth = Convert.ToInt32(textBox1.Text);
multiLayerViewer1.Scroll(1, 1);
//-------------------//
if (multiLayerViewer1.ScrollingPosition.X > 0 || multiLayerViewer1.ScrollingPosition.Y > 0)
button1.Enabled = true;
else if (multiLayerViewer1.ScrollingPosition.X == 0 && multiLayerViewer1.ScrollingPosition.Y == 0)
button1.Enabled = false;
}
catch (Exception ex)
{ }
}
I checked it. Scroll bar was defined, and button was enabled. Please try it. If you have any additional questions please let me know. |
