How can I display the line position in a TextBox on the status bar?
I have added a 开发者_高级运维StatusStrip
control and placed a StatusLabel
inside of it. But now I want to know how to connect it to my TextBox to show the line number and position of the cursor, like: "Line 2, Row 6".
Thank you
Get the index of the caret in the TextBox:
C#
int caretIndex = textBox.SelectionStart;
VB.NET
Dim caretIndex As Integer = textBox.SelectionStart
Get the line number from the caret index:
C#
int lineNumber = textBox.GetLineFromCharIndex(caretIndex);
VB.NET
Dim lineNumber As Integer = textBox.GetLineFromCharIndex(caretIndex)
Get the character index in the current line:
C#
Point characterXY = textBox.GetPositionFromCharIndex(caretIndex); int characterIndex = textBox.GetCharIndexFromPosition(characterXY);
VB.NET
Dim characterXY As Point = textBox.GetPositionFromCharIndex(caretIndex) Dim characterIndex As Integer = textBox.GetCharIndexFromPosition(characterXY)
I guess you can continue from here ...
