I am trying to "highlight" text in a TextBox control during the "Enter" event as follows

private void txtPriorPlantTotal_Enter(object sender, System.EventArgs e

this.txtPriorPlantTotal.SelectionStart = 0
this.txtPriorPlantTotal.SelectionLength = this.txtPriorPlantTotal.Text.Length


However, when I run the program and click on the textbox none of the text is physicaly highlighted. SelectedText shows I have selected all the text in the textbox but nothing is highlighted. I tried a few other textboxes just to make sure it wasn't the control

What gives

C# with framework 1.1

Click to expand...

Try to call the control's 'SelectAll' method. If this doesn't work, add
the code to the control's 'GotFocus' event handler.
 
I have tried using the SelectAll and it still doesn't "highlight" any text
I also tried using the GotFocus event and still nothing. I can see the event being fired and the SelectedText show I have the text but still nothing is highlighted
 
Use TextLength (is one word) instead of Text.Length (note the missing dot)
and it should work. In your example:

Change this line ...

this.txtPriorPlantTotal.SelectionLength =
this.txtPriorPlantTotal.Text.Length;

to ...

this.txtPriorPlantTotal.SelectionLength =
this.txtPriorPlantTotal.TextLength;
