I am drawing a group box at run time with dock top, and inside it I am drawing buttons of fix height and width Autosize property of group box is true. The buttons I am drawing are of less height than the default height of the group box which is acquiring at run time. How can I remove that extra lower bottom space for the group box?
GroupBox gbFreeCust = new GroupBox()
{
Dock= DockStyle.Top,
Text = item.CatName,
AutoSize = true,
AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowOnly
};
pnlFreeCust.Controls.Add(gbFreeCust);
Try to set the Padding or the MinimumSize properties:
GroupBox gbFreeCust = new GroupBox()
{
Dock= DockStyle.Top,
Text = item.CatName,
AutoSize = true,
AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowOnly,
Padding = new System.Windows.Forms.Padding(0),
MinimumSize = new Size(0,0)
};
pnlFreeCust.Controls.Add(gbFreeCust);

I am trying to auto populate some labels using a loop.
Point labelLocation = new Point(5, 15);
// e is an enum passed to the function
// box is a GroupBox passed to the function
foreach(var value in Enum.GetValues(e.GetType()))
{
Label workingLabel = new Label
{
AutoSize = true,
Location = labelLocation,
BorderStyle = BorderStyle.Fixed3D,
Text = value.ToString()
};
labelLocation = new Point(labelLocation.X, workingLabel.Location.Y + workingLabel.Height);
box.Controls.Add(workingLabel);
}
Whether or not autosize is set, the height always returns 23. So if I set autosize to false, I see borders that are too big, but nicely packed together. If I set it to true, I see borders that are perfect, except there are big gaps in between them.
It seems that the border is not the same as the height of the control, and I'm not sure how to adjust it to make them the same.
The AutoSize won't happen until the label is added to a container. So try switching the two lines of code from:
labelLocation = new Point(labelLocation.X, workingLabel.Location.Y + workingLabel.Height);
box.Controls.Add(workingLabel);
to
box.Controls.Add(workingLabel);
labelLocation = new Point(labelLocation.X, workingLabel.Location.Y + workingLabel.Height);
When dynamically creating a label a part of it's text is missing. This is because the size of the label is not wide enough, it cuts of a part of the the actual string.
How do i make that simply stop? I dont want to nor do i remember setting a size to the label. Should it not just continue untill the string is empty?
Example: value = "Berserker's Iron Axe", it only displays "Berserker's Iron", because i have no size set it cust off a part of the string.
PictureBox finalResult_pBox = new PictureBox {
Name = "finalResult_pBox" + i,
Size = new Size(64, 64),
Padding = new Padding(0),
BorderStyle = BorderStyle.FixedSingle,
ImageLocation = spidyApi_idByName_result.results[i].img.ToString(),
};
MessageBox.Show(spidyApi_idByName_result.results[i].name.ToString());
Label finalResult_itemName_label = new Label{
Name = "finalResult_itemName_label" + i,
Text = spidyApi_idByName_result.results[i].name,
};
FlowLayoutPanel finalResult_panel = new FlowLayoutPanel{
FlowDirection = FlowDirection.TopDown,
BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle,
Name = "result_flowLayoutPanel" + i,
Size = new System.Drawing.Size(790, 64),
TabIndex = i,
};
finalResult_panel.Controls.Add(finalResult_pBox);
finalResult_panel.Controls.Add(finalResult_itemName_label);
result_flowLayoutPanel.Controls.Add(finalResult_panel);
Why is this happening and how do i fix this?
As long as you keep Label.AutoSize = true, which is the default it should size itself automatically.
You may want to do some tests to see the actual dimensions, like
setting a BorderStyle
or a BackColor
or inserting a space in the Text, so it gets a chance to go to a second line..
Of course you could measure the Text (with e.g. TextRenderer.MeasureText(text, Label.Font); but that will certainly not be necessary for the text simply to show.. It is useful for more demanding layout control, though.
So the first thing is to make sure that AutoSize is either true or that you measure and set the Size of the Label..
I am using a flowlayoutpanel which have a lot of buttons per logic sake. I'm having an issue of when I resize the window, I'm not I'm not able to see all the buttons lined up horizontally when the window gets smaller. Instead as the window gets smaller, the buttons drops down to the next line. Can anyone help me on how to resolve this issue? I just want the buttons to line up horizontally, when the window gets smaller, have a horizontal scrollbar. Below is what I have.
fLayoutPnl.Controls.Add(btn1);
// snipped adding buttons from 2 to 15
fLayoutPnl.Controls.Add(btn16);
fLayoutPnl.Dock = System.Windows.Forms.DockStyle.Top;
fLayoutPnl.Location = new System.Drawing.Point(0, 10);
fLayoutPnl.Name = "fLayoutPnl";
fLayoutPnl.Size = new System.Drawing.Size(1245, 30);
If you dock the flowlayoutpanel on the top, it take the size of the parent control.
So if you want a horizontal scroll, you need to set the AutoScrollMinSize of the form (or usercontrol).
Otherwise, you can do this :
this.AutoScroll = true;
this.fLayoutPnl.Dock = System.Windows.Forms.DockStyle.None;
this.fLayoutPnl.AutoSize = true;
this.fLayoutPnl.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowAndShrink;
this.fLayoutPnl.Location = new System.Drawing.Point(0, 10);
this.fLayoutPnl.Name = "fLayoutPnl";
this.fLayoutPnl.Size = new System.Drawing.Size(1245, 30);
fLayoutPnl.WrapContents = false;
This would solve the issue. If a scroll bar is needed, set the MinimumSize property of the panel, after which the scroll bar should appear
To view all the contents of flow layout panel by scrolling vertically, set AutoScroll property to True and don't forget to set WrapContents property to True.
If the contents are to be viewed by scrolling horizontally, set AutoScroll property to True and don't forget to set WrapContents property to False.
In WinForms I am using a Label to display different messages like success, failure, etc.
I'd like to center that label in the center form. I want a solution that will keep it centered whether there's just one word or a whole sentence in the label.
Set Label's AutoSize property to False, TextAlign property to MiddleCenter and Dock property to Fill.
You will achive it with setting property Anchor: None.
Some minor additional content for setting programmatically:
Label textLabel = new Label() {
AutoSize = false,
TextAlign = ContentAlignment.MiddleCenter,
Dock = DockStyle.None,
Left = 10,
Width = myDialog.Width - 10
};
Dockstyle and Content alignment may differ from your needs. For example, for a simple label on a wpf form I use DockStyle.None.
If you don't want to dock label in whole available area, just set SizeChanged event instead of TextChanged. Changing each letter will change the width property of label as well as its text when autosize property set to True. So, by the way you can use any formula to keep label centered in form.
private void lblReport_SizeChanged(object sender, EventArgs e)
{
lblReport.Left = (this.ClientSize.Width - lblReport.Size.Width) / 2;
}
The accepted answer didn't work for me for two reasons:
I had BackColor set so setting AutoSize = false and Dock = Fill causes the background color to fill the whole form
I couldn't have AutoSize set to false anyway because my label text was dynamic
Instead, I simply used the form's width and the width of the label to calculate the left offset:
MyLabel.Left = (this.Width - MyLabel.Width) / 2;
I wanted to do something similar, but on a form with a background image, I found that when the text in the label changed the repaints were obvious with this method, so I did the following:
* Set the label AutoSize to true and TextAlign to MiddleCenter
Then, each time the text changed (mine was done using a timer) I called the following method:
private Point GetPosition()
{
int y = (this.Height / 2) - (label1.Height / 2);
int x = (this.Width / 2) - (label1.Width / 2);
return new Point(x, y);
}
And set the label's Location property to this return value. This ensured that the label was always in the center of the form when the text changed and the repaints for a full-screen form weren't obvious.
You could try out the following code snippet:
private Point CenterOfMenuPanel<T>(T control, int height=0) where T:Control {
Point center = new Point(
MenuPanel.Size.Width / 2 - control.Width * 2,
height != 0 ? height : MenuPanel.Size.Height / 2 - control.Height / 2);
return center;
}
It's Really Center
I have a Label on a Windows.Form. I set the AutoSize property on the label to True and I noticed that when I do that, it pads the right hand side with ~5px of white background. I have the Padding property set to [0, 0, 0, 0]. Is there a way to get rid of this?
I would like to get the bounds of the label as close as possible to the text within the label.
There's no way when you use only padding and margin. That's the default behavior.
In the above Window I've set the Padding and Margin to [0,0,0,0]. Those 5 pixels are still there.
If you set FlatStyle = System and AutoSize = False you can get this:
In the above Window you don't have those 5 pixels anymore.
Ok, so FlastStyle = System; AutoSize = false; and then set up a property that will calculate the width like this:
public string LabelText
{
set
{
_label.Text = value;
using (Graphics g = CreateGraphics()) {
_label.Width = (int)g.MeasureString(_label.Text, _label.Font).Width;
}
}
}
