How to give the maximum length of label in .Net.
I have to display 4000 characters in a label.

You want to show 4000 characters but it won't? I don't understand the question.

There is nothing difficult to understand. I want to display 4000 characters in a label. So that all the 4000 characters can be visible to the user.How to set the maximum length of the label?

I don't think so we can set label's maximum length.You can show the 4000 characters to the user by increasing Width property.

why don't you do a function to maximize your 4000 character? it is like

If Len(lblSample) > 4000 Then
lblSample = Left(lblSample, 4000)
End If

(I appologize for my inability to understand your question, despite its lack of detail.)

What kind of application are you building? You have not specified if this is a windows or web form application, though I can assume from the fact that you have not been able to get it to work that you are building a windows form application. Perhaps more detail about your application would be helpful.

I do not know if there are any "visual metrics" capabilities in windows forms controls such that you can determine if the contents of a control such as a label are getting "clipped".

Hi there,

Your question *was* difficult to understand. Since you didn't specify your target application, it was hard to guess what you wanted. By default, a Web "label" will adjust its size to display all 4,000 characters automatically.

Anyway, if you want to measure the size of a String look into the MeasureString method. The following code will tell you how large String to Measure will be:

Code:

string measureString = "String to Measure";
Font stringFont = new Font("Arial", 12);
Bitmap myBitmap = new Bitmap(100, 100);
SizeF stringSize = new SizeF();
Graphics myGrahpics = Graphics.FromImage(myBitmap);
stringSize = myGrahpics.MeasureString(measureString, stringFont);

You'll need the System.Drawing namespace for this work.

The SizeF struct, stringSize, exposes a Height and a Width property of your string in Pixels as a float, so you may need to do some rounding.

I haven't found a way yet to do this without creating the intermediate Bitmap object, but there may be ways around it.

Cheers,

Imar
