I have a label inside a panel. When the text exceeds, the label text should wrap. For doing that I have set mylabel's AutoSize = false and MaximumSize = 100,0.
Now since the text is being wrapped, vertical scrollbar should appear on panel. But that's not happening, please specify what I am missing here.
Is it possible this way or should I explicitly add a vertical scrollbar inside the panel?
1) You need to put the label inside the panel
2) AutoSize for label should be TRUE
3) AutoSize for panel should be FALSE
4) AutoScroll for panel should be True
that is it!
You should be setting AutoSize to true to automatically wrap. For the scrollbars check that you set panel.VerticalScroll.Visible = true;
Did you have the properties Scrollable=true or AutoScroll?
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.panel.scrollbars.aspx
Try this:
ScrollBar vScrollBar1 = new VScrollBar();
vScrollBar1.Dock = DockStyle.Right;
vScrollBar1.Scroll += (sender, e) => { panel1.VerticalScroll.Value = vScrollBar1.Value; };
panel1.Controls.Add(vScrollBar1);
It's long time ago about this question.
Solution :
Panel1.AutoScroll = True
Label1.AutoSize = True
Label1.MaximumSize = New Size(Panel1.ClientRectangle.Width - 18, 0)
Impotrant thing is to define MaximumSize for Label width. Height leave 0 (zero). Height will grow with label content.
In this case, maximum width of label would be width of panel - 18px for scroller.

I'm trying to add x Buttons to a FlowLayoutPanel which is docked (DocType fill) in a Panel.
I have set the FlowDirection to Topdown as I want something like:
However, the FlowLayoutPanel has a horizontal scrollbar, not a vertical one:
I add the buttons like this:
flowLayoutPanel1.Controls.Add(new Button { Text = "Chat", Width = flowLayoutPanel1.Width - flowLayoutPanel1.Margin.Left - flowLayoutPanel1.Margin.Right});
I also tried:
flowLayoutPanel1.Controls.Add(new Button { Text = "Chat", Dock = DockStyle.Fill});
And also:
flowLayoutPanel1.Controls.Add(new Button { Text = "Chat", Anchor = AnchorStyles.Left | AnchorStyles.Right});
I tried this and also looked here. Both don't work for me.
Thanks for your help.
after some digging here I found it out.
I had to set the FlowLayoutPanel.WrapContents Property to false.
I have a Control that ultimately inherits from TextBox
If I don't remove the border then the text vertical alignment is fine:
But I want to remove the border like this:
public partial class MyReadonlyDataField : TextBox
{
private void InitializeComponent()
{
this.BorderStyle = System.Windows.Forms.BorderStyle.None;
this.Appearance.BorderAlpha = Infragistics.Win.Alpha.Transparent;
this.TextAlign = System.Windows.Forms.HorizontalAlignment.Right;
this.Height = 19;
}
}
But then the text alignment is off. How can I fix that?
I solved it. If I set the perfect height for my TextBox control then the text will be centered, because the control has the exact height that matches the text font.
To achieve that I set the hidden AutoSize property of TextBox. It can't be set in the Forms-Designer nor does IntelliSense list it as property. But it exists and works when set to true!
There's some spacing between the Buttons I add to my TableLayoutPanel. I removed the border in the Button and set the Margin and Padding to 0 in the Panel. But I continue getting that spacing.
tableLayoutPanel.RowCount is set to 8 and the Rows collection I've added 8 rows with Size Type Absolute.
Am I missing something? Here's the code:
private void FillSelectLayout()
{
tableLayoutPanelSelect.Controls.Clear();
tableLayoutPanelSelect.RowStyles.Clear();
tableLayoutPanelSelect.RowCount = 8;
for (int i = 0; i < 8; i++)
{
Button buttonSelector = new Button();
buttonSelector.Height = 64;
buttonSelector.Width = 100;
buttonSelector.FlatStyle = FlatStyle.Flat;
buttonSelector.FlatAppearance.BorderSize = 0;
buttonSelector.BackColor = Color.Yellow;
tableLayoutPanelSelect.Controls.Add(buttonSelector, 0, i);
}
}
Here's how it's displayed:
To remove the space between buttons in cells, it's enough to set dock property of them to fill and then remove default margins of buttons:
var b = new Button();
b.Dock = DockStyle.Fill;
b.Margin = new Padding(0);
Note:
Usually it's better to set Dock property of controls which you host in cells to Fill. This way your controls will follow TableLayouPanel sizing rules which you set for columns and rows.
TableLayoutPanel use Margin property of control to set the location of control in cell. So If you don'n want to set Dock and you prefer to set the Size manually, it's enough to set the Margin only.
I .. set the Margin and Padding to 0 in the Panel.
Why didn't you remove the Margin in the Buttons instead:
buttonSelector.Margin = new Padding(0);
MSDN:
The Margin property defines the space around the control that keeps
other controls a specified distance from the control's borders.
I faced the same problem while using different control in TableLayoutPanel
You can do this
Go to Design View
Click on the properties
GoTo Columns, When you click text box besides Columns, a button (...) appears on extreme right, click it
A pop up window appears, Select AutoSize (Instead of Absolute or Percentage).
In the same window in Show: select Rows and again select Autosize.
Click okay and you are done.
I am using visual studio 2012 for this. Basically I have a WinForm that I want to expand.
Inside the form designer, I am able to see that my form has a scroll bar, but when I compile the program, the scroll bar does not appear. The controls that are beyond my screen size are clipped off, as opposed to having a scrollbar.
Are there any settings that I have missed out? Currently I set my AutoScroll = true.
Scrollbars show up when a parent control has the AutoScroll set to true and a child control has a MinimumSize such that the client area of the child control is larger than the client area of the parent control.
E.g.
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
var sampleForm = new Form() { AutoScroll = true };
Panel panel = new Panel() { BackColor = Color.Red, AutoSizeMode = AutoSizeMode.GrowAndShrink, AutoSize = true };
Button btn = new Button { Text = "Toggle MinSize", AutoSize = true };
panel.Controls.Add(btn);
btn.Click += delegate {
if (panel.MinimumSize == Size.Empty)
panel.MinimumSize = new Size(600,600);
else
panel.MinimumSize = Size.Empty;
};
sampleForm.Controls.Add(panel);
Application.Run(sampleForm);
}
If your child panel correctly calculates its preferred size, then you can override the MinimumSize property and return the PreferredSize.
AutoScroll = true is enough to display scroll on form no other setting is required.
just try other thing add panel in form and set panels AutoScroll = true and then add control to it and check that scroll is working or not ?
Take a look at the properties of the controls within the container for which you want autoscroll to work. One possibility is that you set one or more of those controls Anchor property to Right or something, which can reverse the autoscroll setting behind the scenes to effectively turn it off. Also check the RightToLeft property of the container, and try setting that to the default "no"
Make sure you have set Dock.Fill i.e. Dock property to Fill
Set property AutoScroll = true , AutoSize = true, AutoSizeMode = GrowOnly ,you can also do this by adding a panel to the form and set panel AutoScroll = true.
compare your issue with example here
I have a Panel with a Label inside.
Sometimes, the Label is very long and the panel must be resized.
I have set the Autosize property to true for both controls, but ....
Can you help me please ?
You also must set AutoSize to true for the containing containers as well, up to the window.
My last attempt in doing so involved quite a bit of redesigning the form with TableLayoutPanel and the like since Dock/Anchor and AutoSize don't seem to mix well.
I have set the Autosize property to true for both controls, but ....
I can tell from the "but" what you are asking for. That's the AutoEllipsis property of the Label. Set it to true and set the MaximumSize property so the label cannot get bigger than its container. The user will see ... so she'll realize the text is truncated. She'll hover the mouse over the label to get a tooltip with the full text.
Letting everything grow to accommodate a label is drastically impractical. You typically can manipulate MaximumSize to let it grow vertically for a while, up to a point.
I encountered a similar problem, and here is a code for you. Assuming your Panel is anchored to the form (top,left,bottom,right), it is the form that needs to be resized, not the Panel.
public static void FitPanel(Panel pnl)
{
int maxright = 0;
int maxbottom = 0;
foreach (Control ctl in pnl.Controls)
{
maxright = (ctl.Right > maxright ? ctl.Right : maxright);
maxbottom = (ctl.Bottom > maxbottom ? ctl.Bottom : maxbottom);
}
int deltabottom = pnl.Bottom - (pnl.Top + maxbottom);
int deltaright = pnl.Right - (pnl.Left + maxright);
Form frm = pnl.FindForm();
frm.SuspendLayout();
frm.Height = frm.Height - deltabottom;
frm.Width = frm.Width - deltaright;
frm.ResumeLayout();
}
