Resizing Panel Problem

Hi,

I am adding some labels dynamically to a panel. After all the label have
been added, I have calculated a new height for the panel. However when I
try to change the size of the panel, it remains at the size specified in
design view.

Is this not possible or am I missing something?

Mark,

Many thanks for your reply. Here is the code I'm using:

private void frmViewSchedule_Load(object sender, System.EventArgs e)
{
this.intStepValue = 0;
try
{
XmlNodeList xnlJobs =
this.mScheduling.GetAllUnchangedDetails(JobPriority.High);
for(int i = 0; i < xnlJobs.Count; i++)
{
ScheduleLabel slTmp = new ScheduleLabel(0, this.intStepValue,
this.panViewScheduleMain.Width, 20,
Convert.ToInt32(xnlJobs.Attributes["index"].Value),
xnlJobs["job_properties"].Attributes["housenumber"].Value + " " +
xnlJobs["job_properties"].Attributes["housenumbersub"].Value + " " +
xnlJobs["job_properties"].Attributes["streetaddress"].Value + " " +
xnlJobs["job_properties"].Attributes["postcode"].Value,
(xnlJobs["job_response"]["job_response_details"] != null) ?
xnlJobs["job_response"]["job_response_details"].Attributes["description"]
..Value : "N/A", JobPriority.High, this.lblJobDetails);

this.panViewScheduleMain.Controls.Add(slTmp);
this.intStepValue += 25;
slTmp = null;
}
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}

this.panViewScheduleMain.Height = this.intStepValue;

}

The ScheduleLabel control is as follows:

public class ScheduleLabel : System.Windows.Forms.Control
{
private int intX;
private int intY;
private int intWidth;
private int intHeight;
private int intIndex;
private string strSummary;
private string strFullDetails;
private Label lblFullDetails;
private JobPriority jpPriority;
public ScheduleLabel(int intX, int intY, int intWidth, int intHeight, int
intIndex, string strSummary, string strFullDetails, JobPriority jpPriority)
: this(intX, intY, intWidth, intHeight, intIndex, strSummary,
strFullDetails, jpPriority, null)
{
}
public ScheduleLabel(int intX, int intY, int intWidth, int intHeight, int
intIndex, string strSummary, string strFullDetails, JobPriority jpPriority,
Label lblFullDetails)
{
this.intX = intX;
this.intY = intY;
this.intWidth = intWidth;
this.intHeight = intHeight;
this.intIndex = intIndex;
this.strSummary = strSummary;
this.strFullDetails = strFullDetails;
this.lblFullDetails = lblFullDetails;
this.jpPriority = jpPriority;
InitializeComponent();
}
public override string Text
{
set
{
base.Text = value;
Invalidate();
}
}
public string Summary
{
get
{
return this.strSummary;
}
}
public string FullDetails
{
get
{
return this.strFullDetails;
}
}
public int JobIndex
{
get
{
return this.intIndex;
}
}
private void InitializeComponent()
{
base.Location = new Point(this.intX, this.intY);
switch(this.jpPriority)
{
case JobPriority.High: this.BackColor = Color.Purple;
base.ForeColor = Color.White;
break;
case JobPriority.AM: this.BackColor = Color.Purple;
base.ForeColor = Color.White;
break;
case JobPriority.PM: this.BackColor = Color.Purple;
base.ForeColor = Color.White;
break;
default: this.BackColor = Color.Purple;
base.ForeColor = Color.White;
break;
}
base.Width = this.intWidth;
base.Height = this.intHeight;
base.Text = this.strSummary;
base.Click += new EventHandler(ScheduleLabel_Click);
}
protected override void Dispose(bool disposing)
{
base.Dispose(disposing);
}
protected override void OnPaint(PaintEventArgs pe)
{
Graphics gr = pe.Graphics;
SolidBrush b = new SolidBrush(ForeColor);
gr.DrawString(base.Text, base.Font, b, 5, 2);
b.Dispose();
}
private void ScheduleLabel_Click(object sender, EventArgs e)
{
if(this.lblFullDetails != null)
{
this.lblFullDetails.Text = this.strFullDetails;
}
}
}

Many thanks for your help. Sorry it has taken a while for me to reply, but
I have only just had time to look at this problem again. Not sure why it
wasn't working before, but since trying it again everyting seems to be
working. It may have something to do with the order I was adding stuff. I
was woring through
http://msdn.microsoft.com/library/d...s/dnnetcomp/html/netcfimproveformloadperf.asp
and when I ran the code the panel behaved as required.

Again many thanks for taking the time to reply and try the code yourself.

of 0 and once the loop completed the panel was resized. Here is the modifed
code i used which was run from my form load. I didn't modify your
ScheduleLabel class. Email me if you still have problems.
this.intStepValue = 0;
try
{
for(int i = 0; i < 20; i++)
{
ScheduleLabel slTmp = new ScheduleLabel(0, this.intStepValue,
this.panViewScheduleMain.Width, 20,
Convert.ToInt32(i),
"housenumber" + i.ToString() + " " +
"housenumbersub" + i.ToString() + " " +
"streetaddress" + i.ToString() + " " +
"postcode" + i.ToString() + " ",
"job_response_details" + i.ToString(), JobPriority.High, this.lblJobDetails);

this.panViewScheduleMain.Controls.Add(slTmp);
this.intStepValue += 25;
slTmp = null;
}
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}

this.panViewScheduleMain.Height = this.intStepValue;
