Adding controls to a panel dynamically.

[Big D]

Hi all,

I'm having a problem adding controls to a panel dynamically. I have a
usercontrol that I create and try to add 5 times to the panel, but I only
ever see the first control. I know it's the first, because a property of
the userControl is to display it's name. The code I have is:

//Add detatil widgets to the panel

CustControls.DetailWidget x;

for (int i = 0; i<5; i++)

{

x = new CustControls.DetailWidget();

x.Name = "asdf" + i.ToString();

x.Location = new Point(i * 10, i * 10);

this.pnlDetailContainer.Controls.Add(x);

}

How is this supposed to work? Should the panel automatically place each
control under one another or next to one another or must that be done
entirely by hand?

Thanks!

Your code snippet looks right. Why don't you check programmatically if all
the controls are in the container, say

foreach (Control x in this.pnlDetailContainer.Controls)
{
MessageBox.Show(x.Name);
}

If you see all the added controls, then may be it's a paint issue or
something to do with your control itself (like your control choosing its own
location, etc.)

Hi

I think the problem should be your user control, because I have tried to
add 5 textbox into the panel, it just works well, code snippet like this:

private void Button1_Click(object sender, System.EventArgs e)
{
for(int i=0;i<5;i++)
{
TextBox tb=new TextBox();
tb.Text="textbox"+ i.ToString();
tb.ID=i.ToString();
Panel1.Controls.Add(tb);
}
}

I think you should check the implement of your user control.
