I'm concatenating a string that sometimes is long enough for it not to fit in a label control. How can i make it autoscroll to the rightside so i always see the end of the string?
While I'm sure there are ways of doing, I have to ask, why? I think it would look and/or work very badly and probably confuse the user.
Why not have the text get trimmed with an ellipse (...) at the end and show a tooltip on the label?
using System.Windows.Forms;
var label = new Label();
label.AutoSize = false;
label.AutoEllipsis = true;
label.Text = "This text will be too long to display all together.";
var labelToolTip = new ToolTip();
labelToolTip.SetToolTip(label, label.Text);
Now the tooltip will show the full text when the user hovers over it. Since the text in the label will be truncated and end in an ellipse, the user should know to hover over for more info (usually the standard way).
The TextAlign property allows you to specify the alignment. If you right-justify it with this, the right side of the text will always be visible. However, if you want it to be left or center justified and still have the behavior you describe, I suspect you will need to perform some measurement using Graphics.MeasureString to determine if the text fits and change the alignment dynamically.
AFAIK there's no way to scroll a label. A hack would be to use a TextBox (read-only, turn off border) then use SendKeys.Send() to move the cursor to the end of the text. Something like:
textBox1.Focus();
SendKeys.SendWait("{END}");
To get the text to not show up as selected I had to change it's position in the tab order (so that it wasn't 1) but that may not be a problem in your case.

I have a button on a C# Windows Form form, and want to show an image and some text, side by side, and centered on the button. I tried aligning the image to the left and the text to the right, and I'm getting this (the periods are spaces):
|[IMAGE}.................Text|
But I want this:
|........[IMAGE] Text........|
My code looks like this:
btnChangeStatus.Text = "Change status to SUPPRESSED";
btnChangeStatus.TextAlign = ContentAlignment.MiddleRight;
btnChangeStatus.Image=Image.FromFile(#"J:\nomail.gif");
btnChangeStatus.ImageAlign = ContentAlignment.MiddleLeft;
I've searched here, and found lots of stuff for Java or HTML, but nothing for C#. Any ideas?
Thanks!
Set TextImageRelation to TextImageRelation.ImageBeforeText:
btnChangeStatus.TextImageRelation = TextImageRelation.ImageBeforeText;
btnChangeStatus.TextAlign = ContentAlignment.MiddleCenter;
btnChangeStatus.ImageAlign = ContentAlignment.MiddleCenter;
Specifies that the image is displayed horizontally before the text of a control.
UPDATE: You are right, though it sounds like this should do what you want, it's still a little to the left.
I tried around a little and using
btnChangeStatus.TextImageRelation = TextImageRelation.ImageBeforeText;
btnChangeStatus.TextAlign = ContentAlignment.MiddleRight; // <- right here
btnChangeStatus.ImageAlign = ContentAlignment.MiddleCenter;
leads to the desired result, but I can't tell why the button behaves like that.
I have been trying to find how to change a rich text box into ONE color specifically, not multiple colors in one. Google has been no help, because it assumes I am looking for multiple lines of random colors. I saw nothing here, but I'm sure there is something on here, but I have yet to figure out how to ask the question properly I guess. So I ask it here. How do I do it? My code only displayed the color name in the rich text box, and changed the color of the start button which is not at all what I want. The eventual idea will be that everything that is typed that is the same, will be of that color. I figured this would be the simplest way of accomplishing that.
This is what I typed:
if(TypeHere.Text == DisplayText.Text)
{
DisplayText.Text = Convert.ToString(ForeColor = System.Drawing.Color.Blue);
}
That obviously didn't work like I thought it would. I'm sure I'm either missing a crucial step, or not entirely understanding how colors work on WF. I placed this in the TypeHere. The output of this in DisplayText is:
Color[Blue]
It wouldn't let me just set DisplayText to equal the color implicitly. I realize why it displays the name in the textbox, but I don't understand why it changes the color of the text in my button? I've tried it both as a method, and a couple of lines of code in the text box. So it's obviously not where I place the code, but something else.
Set the ForeColor property of the RichTextBox. This will change the font color in the RichTextBox.
richTextBox1.ForeColor = Color.Blue;
I'm making a calculator in c#. I know the logic required to make a calculator. But the problem I'm facing is with the UI, I want to make the text in my TextBox Right and Bottom, while there is TextAlign property which makes the text in the TextBox align to right, I'm having trouble making it align to the bottom?.I really tried finding an answer.
but I want something like this
Also how to move the text in the textbox slightly upper when I press any operator?
Assuming the fact that you only use the TextBox for displaying the user input, a Label will allow for better use of what you want.
The Label supports a wider use of TextAlign so you could use
Label1.TextAlign = ContentAlignment.BottomRight;
If you want to create multiple lines inside the label, you can use Environment.NewLine to achieve that for example. But a StringBuilder and using AppendLine will probably work too.
If you really need to use a TextBox to achieve your needs, your best option would probably be to write a custom TextBox which supports your wanted text align.
Think this is possible with a RichTextBox but it would be a long work around. I would suggest using a Label. To align the text to the bottom right in a label you can use:
label.TextAlign = ContentAlignment.BottomRight;
To change the look of the Label you can use:
label.BackColor = Color.White;
label.BorderStyle = BorderStyle.FixedSingle;
To change the label from looking like a single line:
label.AutoSize = false;
label.Size = new Size(100,100)
I need to adjust height of the textbox so it is suitable for touchscreen.
I understand people recommend Multiline = "true" but if I do that, text inside of the box is justified with top which is not proper in my application.
I tried to adjust font size, but the size should be ridiculously huge to fit the height for my need.
Is there any other way to increase the height of textbox?
Try this:
textBox1.AutoSize = false;
It won't show up in the intellisense, but it will work.
To have it work with the designer, you would have to make your own TextBox:
public class TextBoxEx : TextBox {
public TextBoxEx() {
this.AutoSize = false;
}
}
Trick steps:
Set the multi-line = true
No need to change the Font size.
change the Max-length . so that it should not enter the next line.
For what I wanted to do using a label instead with BorderStyle=Fixed3D and AutoSize=False did the trick.
In the process of translating an application with C# + Winforms, I need to change a button's text depending on the language.
My problem is the following :
Let's say I want to translate a button from "Hi all!" to "Bonjour tout le monde" !
As you can guess, the button's size won't be the same if I enter english text or french one... My question is "simple", how can I manage to resize the button on the fly so the text fits its content in the button ?
So far I got something like that !

There's absolutely no need to use the underlying Graphics object as the other posters have said.
If you set the button's AutoSize property to true, the AutoSizeMode to GrowAndShrink, and the AutoEllipsis to false, it will resize automatically to fit the text.
That being said, you may need to make several layout adjustments to make this change fit into your UI. You can adjust the button's padding to add space around the text, and you may want to place your buttons in a TableLayoutPanel (or something) to stop them from overlapping when they resize.
Edit:
#mastro pointed out that: AutoEllipsis is only valid when AutoSize is false (As explained in the documentation), so it can be safely ignored as long as the other three properties are set correctly.
Your best bet is to set the AutoSize property as described ach's answer
However if AutoSize isn't working for you, resizing the button in code is easy enough. You can just need to set the button's width. The trick is making it big enough to fit your text.
using(Graphics cg = this.CreateGraphics())
{
SizeF size = cg.MeasureString("Please excuse my dear aunt sally",this.button1.Font);
// size.Width+= 3; //add some padding .net v1.1 and 1.0 only
this.button1.Padding = 3;
this.button1.Width = (int)size.Width;
this.button1.Text = "Please excuse my dear aunt sally";
}
Try this:
Button.AutoSize = true;
Button.AutoSizeMode = System.Windows.Forms.AutoSizeMode.GrowOnly;
Button.TextAlign = ContentAlignment.MiddleLeft;
Button.Padding = new Padding(0, 0, 0, 0);
To enable a Button in WinForms grow and/or shrink depending on the size of the Text, you need to set the button's AutoSize property to True and the AutoSizeMode property to GrowAndShrink.
// C#
btn.AutoSize = true;
btn.AutoSizeMode = AutoSizeMode.GrowAndShrink;
' VB.NET
btn.AutoSize = True
btn.AutoSizeMode = AutoSizeMode.GrowAndShrink
Please note that the AutoSize property will only allow the button's size to grow if the AutoSizeMode property is set to GrowOnly; by changing the AutoSizeMode property to GrowAndShrink, the button will now automatically extend or reduce in width and height based on its Text property.
Also note that in setting the two properties as shown above, you can make use of new lines (Environment.NewLine or vbCrLf) in the Text property and the button will scale down as needed.
As Andrew Hanlon explains, you can set AutoSize = true.
When doing so, you can also attain a perfect layout of the buttons automatically by placing them on a FlowLayoutPanel.
The horizontal distance between them will always stay the same when the FlowDirection of the FlowLayoutPanel is LeftToRight or RightToLeft. You can adjust this distance by setting the Margin property of the buttons appropriately. You can create groups of buttons by increasing the left margin of buttons beginning a new group.
If you set the Dock property of the buttons to DockStyle.Fill, they will even grow their width automatically in order to fit to the widest button if the FlowDirection of the FlowLayoutPanel is TopDown or BottomUp.
btn.AutoSizeMode = AutoSizeMode.GrowOnly;
btn.AutoSize = true;
btn.Dock = DockStyle.Fill;
In addition to setting the AutoSize to true and the AutoSizeModeto GrowAndShrink, as suggested in the other answers, you may also need to set the TextImageRelation property, if you have set the button image, so that the text doesn't overlap the image.
