Question

Can't change text in TextBox Control

Asked by: C_Sharp_Programmer

I have a mobile application I am developing in Visual Studio 2008 for a Windows Mobile 5.0 Pocket PC.  I have several TextBox controls on the form, as well as a button to enable/disable them.  When the button is pressed I set the focus of the first TextBox:

txtName.Enabled = true;
txtName.focus();

I also enable the on-screen keyboard:
inputPanel.Enabled = true;

However, I cannot change the text in the TextBox control. I can highlight it, and the Tab key works to tab between controls, but I cannot type anything into the TextBox itself (the TextBox is not set to ReadOnly).

Any helpful ideas? Thanks!

can you do a MessageBox.Show(txtName.Enabled);  so we can know the state of the textbox when  you want to edit it?

 

by: C_Sharp_ProgrammerPosted on 2009-09-22 at 12:06:23ID: 25396305

The result of:
MessageBox.Show(txtName.Enabled.ToString() + "\n" + txtName.ReadOnly.ToString());

is:

true
false

So it's definitely enabled and not read only.  Again, I can use the arrow keys on the on-screen keyboard to move the cursor position within the TextBox, and the tab key works to tab between it and other controls, but when I try and type anything (including backspace), nothing happens. Ctrl + C does not work to copy the text either...

Any thoughts?
Thanks!

is there any handlers?
Can you create a new textbox with no code behind it and see if you can change the text? Maybe the form is locked or something.

 

by: C_Sharp_ProgrammerPosted on 2009-10-07 at 19:28:38ID: 25522000

Mikal613, Thank you for the suggestion, There was a KeyDown event handler that was prohibiting any text from being changed in the Textbox.  I modified the handler, and it worked like a charm.
