I have set up the textbox to show the MfgControl.AdvancedHMI.Controls.AlphaKeyboard on click. It then returns the typed in value to the text box. If I click on the textbox with text already there, the MfgControl.AdvancedHMI.Controls.AlphaKeyboard clears the data and I have to retype the entire number. Can I have the MfgControl.AdvancedHMI.Controls.AlphaKeyboard show the current textbox value for editing?
