Hello,

I have a label that displays data from a database.  I would like to add some code which would only display the first 30 characters and then at the end it would have a link that would open a message box and display all the text.

Is something like this easy to create?

Thanks.

You could very easily call <string>.Substring(0,30) to display the first 30 characters if your string is over 30 characters. You can then add a ToolTip object onto your form at design time, which will then expose a property on your label to set the ToolTipText, so that the full text will display on hover. You can call the ToolTipText property within code.

I missed the message box. You could also show/hide a LinkLabel or a Button that will show the full text in a MessageBox. You could also make the original label a LinkLabel as well.

Yes. Let's say you've a label named 'lblName'
in the code behind do the following
if (<yourtext>.Length > 30)
{
lblName.Text = Left(<text>, 30) + "<a href='javascript: alert(\"" + <text+ "\")'>Click here to view the full name</a>";
}
else
{
lblName.Text =<text>;
}

First 30 Characters will cut off words. In code is a function to get the first x words. Your choice.

label1.Text = FirstWords(myString, 10)

If you insist on using first 30 chars try:

label1.Text = myString.Substring(0, 29);

for the popup i don't know.. is this a ASP.Net webform or Windows Forms Application?

    public static string FirstWords(string input, int numberWords)
    {
        try
        {
            int words = numberWords;
            for (int i = 0; i < input.Length; i++)
            {
                if (input[i] == ' ')
                {
                    words--;
                }
                if (words == 0)
                {
                    return input.Substring(0, i);
                }
            }
        }
