How to select again the previously selected text after changing its case in WinForms SyntaxEditor (EditControl)?

Platform: WinForms |
Control: EditControl

Select the text

The SetSelection() method is used to select the text in EditControl. We need to invoke SetSelection() method after converting the case of the SelectedText.


//Selecting the text after converting to lowercase
string lowerCaseStr;
lowerCaseStr = this.editControl1.SelectedText.ToLower();
this.editControl1.SelectedText = lowerCaseStr;
this.editControl1.SetSelection(col - lowerCaseStr.Length, this.editControl1.CurrentLine, col, this.editControl1.CurrentLine);
//Selecting the text after converting to uppercase
string upperCaseStr;
upperCaseStr = this.editControl1.SelectedText.ToUpper();
this.editControl1.SelectedText = upperCaseStr;
this.editControl1.SetSelection(col-upperCaseStr.Length, this.editControl1.CurrentLine, col, this.editControl1.CurrentLine);



`Selecting the text after converting to lowercase
Dim lowerCaseStr As String
lowerCaseStr = Me.editControl1.SelectedText.ToLower()
Me.editControl1.SelectedText = lowerCaseStr
Me.editControl1.SetSelection(col - lowerCaseStr.Length, Me.editControl1.CurrentLine, col, Me.editControl1.CurrentLine)
`Selecting the text after converting to uppercase
Dim upperCaseStr As String
upperCaseStr = Me.editControl1.SelectedText.ToUpper()
Me.editControl1.SelectedText = upperCaseStr
Me.editControl1.SetSelection(col-upperCaseStr.Length, Me.editControl1.CurrentLine, col, Me.editControl1.CurrentLine)
