How to place user controls dynamically on a windows form
-
Hi, In my project I have to place the existing user controls dynamically on a form at the given location. That is I will give the X-axis and Y-axis values in the text boxes dynamically then the existing user control should be dynamically created at that location. If any one have any idea to solve this, please reply me as soon as possible. Thanks in advance.

This is quite trivial, you should buy a book and read it. The Petzold book is good in this regard. You add the control to the form's controls collection and you set it's position.

If using 2.0 or above you can use a generic function such as this in your form.
private void AddControl<T>(string text, Point location, Size size) where T : Control, new()
{
T control = new T();
control.Text = text;
control.Location = location;
control.Size = size;
this.Controls.Add(control);
}and call it like
AddControl<Button>("New Button", new Point(12, 12), new Size(75, 23));

unless I'm missing the point entirely wouldnt it be something along these lines:
yourControl.Left = Convert.ToInt32(yourXPosTextBox.Text);
yourControl.Top = Convert.ToInt32(yourYPosTextBox.Text);or at least thats how I position controls within a form, if you mean something else ginore me :)

Why are you using VB6? Do you hate yourself? (Christian Graus)Well blinking 'eck. I never knew that Control had a text property. Just assumed it was lower down in the class hierarchy on certain controls. That's what I've learnt today. :)

Control has got way too many properties IMO. Deriving from it to create a new control is a PITA as you have to try and hide all the non relevant ones (and methods too) which is not only messy/time consuming but very non OOP. If they had a IControl interface that just had the basics required, and a form's Controls property was a list of IControl it would be way better. Something like
interface IControl : ISynchronizeInvoke, IWin32Window
{
bool Enabled { get; set; }Point Location { get; set; } Size Size { get; set; } bool Visible { get; set; }}
public abstract ControlBase: IControl
{
// Implement derived stuff here
...
//
}It'll never happen though :( [Edit] Made a mess of Interface with ControlBase stuff in it :doh: [/Edit] Actually, now I've thought about it a few minutes - just the ControlBase (would need a little more than I provided so we can have OnPaint etc to override) would be enough. Give me ten minutes and I'll probably change my mind again!
