Hi.

I'm making a html-editor and I want to have a function that inputs HTML-tags before and after a marked word. This is the code:

string strInsertBefore = "<a>";
string strInsertAfter = "</a>";

string text = textBox4.Text.Substring(textBox4.SelectionStart, textBox4.SelectionLength);

text =  strInsertBefore + text + strInsertAfter;

string strInsert = text;

textBox4.Text = textBox4.Text.Insert(textBox4.SelectionStart, strInsert);

This results in <a>hello</a>hello .

but i want it to result in <a>hello</a> only.
But i can't get it to work!

Here is a code that I've tried which removes the marked word.

textBox4.Text.Remove(textBox4.SelectionStart, textBox4.SelectionLength);

Thank you!

Solution 1

Have you considered combining the two functions?
First, remove the word from your textbox.
Then, insert the word, surrounded by the HTML tags...

Solution 2

why don't you simply insert strInsertBefore and strInsertAfter at the right places

textBox4.Text = textBox4.Text.Insert(textBox4.SelectionStart, strInsertBefore );

textBox4.Text = textBox4.Text.Insert(textBox4.SelectionStart + textBox4.SelectionLength + strInsertBefore.Length, strInsertAfter);

thing is untested code, you will need to adjust the index for the second one as needed.

Better solution: insert the second one first...

Why didn't I think about that.
