I have a TextBox(Multiline) problem in C#. do u have any solution?

I have a TextBox(Multiline) problem in C#.


For example, if i type "apple" (in lower case), Expected ouput is "APPLE". But the outcome is, "ELPPA".


The Cursor is not working as per our expectation.


Cursor moves to left-sided end when we type.





Purpose of the code: "To convert the (input) text typed in to Upper Case by using a method. And strictly without using the CharacterCasing property of TextBox to convert case".


Pls try to give me a good solution, iff u hav any solution.


I'm facing problem with the code below.


Pls solve it ASAP


Thanx in Advance.





Code:





public String ToCaps(String str)





{


return str.ToUpper();


}





private void textBox1_TextChanged(object sender, EventArgs e)


{


try


{


textBox1.Text = ToCaps( textBox1.Text);


}


catch (Exception ex)


{


Environment.Exit(1);


}


}

better ask a real computer programmer about this case...
Reply:Nope.
Reply:it is because, when you this:


textBox1.Text = ToCaps( textBox1.Text);





The Event textBox1_TextChanged is again fired.





Try using KeyPress event:


private void textBox1_KeyPress(object sender, KeyPressEventArgs e)


{





if (e.KeyChar %26gt;= 'a' || e.KeyChar %26lt;= 'z')


e.KeyChar = char.ToUpper(e.KeyChar);








}


You might require to add some more validation.
