When I add an item to a listbox in c#, if the string is > 4680 characters it displays as a blank line. I can still access the entire string from within the program.
Did I run up against a limit or am I doing something wrong?
The limit of text in a textbox is 64 KB worth of text. Here ya go.
displaying 4680+ characters for a single list item is not useful for the end user. You need to truncate the text or find another way to reference the text that is more user friendly.

Now, I'm trying to create a novel(boot) text reader by C# WPF.
I am facing on a problem.
I don't know how can I split a string(from a text file) as a page of screen. ( like a book page )
(a page of screen is implmented by a label UI control. )
Because the string has 'New Line \n' & 'Tab' character.
So I cannot count how many characters can be inserted into a label(a page of screen).
label.TextLength returns the numbers of characters which can insert into the label.
But, if the string has '\n', it makes a lot of blanks.
So I hope to know how can I count the length of string which can inserted into a label with '\n'.
Or, Please guide me how can I create this program easily by using another UI controls.
< Additional info >
Thanks for your opinion. I added how I use label control.
In default label UI control changed it's size by the string which is inserted the label.
However, In this program, I will fix the label control size. It's size will be fit in Form size.
So, I should know the width & height(lines) of the label.
Or I hope to know controls or libraries for my program.(Unfortunately, I can't found it yet.)
Thank you!
Your label can have AutoSize=true and MaximumSize=new Size(maximumPageWidth, 0);
This way your label will automatically word wrap when maximum width is reached. Every line will only increase the height of label.
Then you will need to add your text to this label line by line. Every time you add a line to this label, check if maximumPageHeight is reached or not.
If maximum height is reached then that's where your page ends. After this you need to add your next line to new page.
Edit: Above solution will work if you use System.Windows.Forms.Label
FlowDocument is the solution what I want!
Thank you to let me know that thing. - cicciorocca!!
This should be very simple.
I have a Label control on my Form and I am trying to put a tab character between text
Label.Text = "Is there a\ttab";
The output is "Is there atab";
What am I doing wrong?
Tab is actually a non-printing character—or rather, a control character. What it does is entirely dependent on the application. What exactly do you expect? 8 spaces? 4 spaces? As many spaces as needed to get to a multiple of 8 columns? Indentation of the following text by one cm?
To put it short: The Label control doesn't support tabs. Actually, Label just uses normal graphics routines for rendering its text and how should they know what you intend to do with your tab character?
If you need to display that character as a number of spaces, then you should replace it by that number of spaces.
I wanted to add tabs ("\t") to a dropdown list of items. The items have a ToString method that gives about 3 words concatenated together. They did not line up. For example:
1-I 45
123-AB 511
123456-MMM 611
A long list like this is hard to read. So I used string.Format like this:
string.Format("{0,6}-{1,-4} {2}",id,name,num);
The number after the comma will right align/pad if positive and left align/pad if negative.
Then I changed my font in the Combobox to be monospaced, like Courier New, and you get something like this:
1-I 45
123-AB 511
123456-MMM 611
That is much easier for a user to read.
Nothing, windows forms labels are very limited in functionality and don't support the \t character.
A (slightly awkward) alternative might be:
label1.Text = "test\ting\t123".Replace("\t"," ");
Old thread, but since none of the answers seemed to work for me, I will go ahead and throw in my 2 cents. I could not get a "\t" or even use manual spaces to add spacing to the label. What I ended up doing was using alt code alt-255 5 times. This worked like a charm. Gotta love total hacks...
Right, to insert a tab, just add the spaces desired.
If you want to offset the next by a specified length, you could try
int offset_text = 20;
label1.Text = "Is there a".PadRight(offset_text)+"Tab";
label2.Text = "More Text".PadRight(offset_text)+"Too";
Just use a literal string and you should be good to go...
label1.Text = #"Test for Tab";
Where that big space is where I actually hit tab three times...hope this helps
I had the same problem. A textbox does instead a label accept Tabs. So if you change the label in a textbox, the pro
Just click in the arrow at the right of the Text property of the label (click in the Text property content and the drop-down-arrow will show up). A box for text-editing will open, and in that box you can use Enter, Tab, and so on.
So I have a listView that references a series of rtf files saved to my disc. When you click on a list item it will display the contents of the rtf file in a RichTextBox.
I want to implement a TextBox that will reorder the list based on the number of times the TextBox's string appears in each rtf file (ideally excluding rtfs that don't have the string altogether)
Anyone have any ideas how to approach this?
I would probably build a list of the strings along with a count, starting at 0, when you go through the files, and just increment it whenever that word is found. Then you can order your list based on the counts it gives.
Currently i'm generating a PDF using iTextSharp in ASP.Net.
One of a field of variable lenght needs to be underlined. Actually in the output file the particular field is shown with lines (as in a ruled notebook).
For example, the field has been allocated 10 lines, so that the user can fill-in depending upon the requirement he has or may be left blank. But, now after automation, data will be fed by the user, which will be later generated as a PDF file, and this particular field is of variable length.
Is there a way i can underline the leading spaces of the field, say only 500 out of 1500 chars width is filled and rest 1000 chars can be underlined. Is there any way i can achieve it with iTextSharp.
i tried it by appending underscores to the actual data (while retrieving it from DB) and underlining the text data by assigning the underline property to the chunk class, but didn't help.
Thanks for any pointers/advise/suggestions
Download http://www.manning.com/lowagie2/samplechapter2.pdf and take a look at the figures in section 2.2.6. Is that more or less what you're looking for? In that case, you need to use a LineSeparator as described in that section.
This should be very simple.
