Listbox items text and text boxes? - Derek275 - 11-20-2012 Ok, I have I have a list box, kryptonListBox1, and a text box textBoxX1. I want to get the selected item in the listbox's text into the text box. My code is: textBoxX1.Text = kryptonListBox1.SelectedItem.ToString I've tried using .Text.ToString, but with both I get the error 'Object reference not set to instance of an object' What am I doing wrong and what's the easiest way to fix it? Re: Listbox items text and text boxes? - Derek275 - 11-20-2012 Also, to clear something up, when it's using .Text.ToString, it says 'Object variable or With block variable not set' Re: Listbox items text and text boxes? - Snake_eyes - 11-21-2012 The code you are using should work fine but just in case try with the code below: [code2=vbnet]TextBox1.Text = KryptonListBox1.SelectedItems.Item(0).ToString[/code2] Try using break points and trace the error because the problem is not with the code you're using. Also try to use a try/catch block and see if that corects the problem by ignoring it. For further help please provide more info like what kind off error it is , where exactly are you using the code and so on.. Re: Listbox items text and text boxes? - brandonio21 - 11-21-2012 As Snake_eyes suggested (Thanks!), this code should definitely work. The error may be appearing due to the fact that a valid item is not actually being selected. You can try to make sure an item is being selected by checking first, like so: [code2=vbnet]If Not (kryptonListBox1.SelectedItem Is Nothing) Then textBoxX1.Text = kryptonListBox1.SelectedItem.ToString End If[/code2] |
