Remove empty textbox spaces

He was commenting on the formatting of my post, but you should note how he set up his if-statement. :)

I was trying to move some the labels with the location.Y method but it doesn't seem to be working. Any help on how get rid of the empty labels as well?

Use the visible property shown in Deresen's post to hide labels you don't want shown. The labels should be able to move the same as your textboxes.

if (String.IsNullOrEmpty(textbox.Text))
{
textbox.Location.Y -= textbox.Height;
label.Location.Y -= textbox.Height;
}

--------info-------- i want to remove the space created by the empty textbox/label or move it to another location where it doesn't take up space

I understand. In theory I figured it would work to move the controls below the empty textboxes up to fill in the gap, however I can't seem to get it working. Hopefully someone a little more knowledgeable will swing by. In the meantime I'll try and figure it out myself and let you know if I come up with anything. I'm still a newbie, myself.

Error 646 'System.Web.UI.WebControls.Label' does not contain a definition for 'Location' and no extension method 'Location' accepting a first argument of type 'System.Web.UI.WebControls.Label' could be found (are you missing a using directive or an assembly reference?)

That's the error is got when i tried using the Location.Y method

Ah, I think I've figured it out. Read this: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.location.aspx[^] And you should understand why you have to do it like this:

if (String.IsNullOrEmpty(textbox.Text))
{
textbox.Location = new Point(textbox.Location.X,(textbox.Location.Y - textbox.Height));
label.Location = new Point(textbox.Location.X, (textbox.Location.Y - textbox.Height));
}

Again, I think it should work but I could be wrong. Hahaha...

So you have this: line 1 line 2 line 4 and you want to have it like this: line 1 line 2 line 4 If I understand you well, you would like to have it is above. If that is what you want, you have to program dynamically. This is what I always do when it is about dynamic programming:

String[] myLines = {"line 1", "line 2", "", "line4"};
int lineheight = 23;//pixels between the labels
int top = 10;//align from top
int left = 20;//left align
int width = 200;
Label l;

foreach(String myLine in lines)
{
if(!String.IsNullOrEmpty(myLine))
{
l = new Label();
l.Location = new Point(left, top);
l.Width = width;
l.Text = myLine;
this.Controls.Add(l);//this will only work if the class you're working in is a Control class like form
top += lineheight;
}
}

textBox.Location.X is the same as textBox.Left and textBox.Location.Y is the same as textBox.Top It's not that your code is bad, because it's the same. But it's a little shorter.

Ah, I see! Thanks Deresen, that will be handy to know! :laugh:
