How would I go about checking if a control (in this case a textbox) is selected? I have searched Google as well as gone through all of the possible functions and still found nothing. I know it's relatively easy as I've seen it done before but I can't remember how.

View 3 RepliesMy code follows. I have six items (indices 0-6) and I'm trying to check if one has been selected or not. If not, then messagebox yells at you to select one. If it does, it tells you what you have selected. I'm having a horrible brain fart and contemplated coming here for about 45 minutes as I couldn't get it.
If ListBox1.SelectedItem.ToString <> "" Then
MessageBox.Show("You selected " + ListBox1.SelectedItem.ToString)
Else
MessageBox.Show("Please select an item.")
End If

View 3 RepliesHow do I make an if statement that would check if the user has selected an option from the select list named cboGrade and also to check if the user has selected a radio button from the group named gbCalcType? I have an action that is carried out when a button is clicked, but before that action is carried out, I need to check the above.
I have this so far:
If rbPlus.Checked Or rbMinus.Checked Or rbMultiply.Checked Or rbDivide.Checked Then
instructions are here
End If
This checks that one of the radio buttons are selected. How do i check that an option is selected from the option list? There are three options: 3rd, 4th, and 5th. And the text starts out saying Select One and it locks the control once they choose one.

View 2 RepliesI have a dropdown list that will add new titles to my database, however I would like to add a textbox that will allow the user to type in a new title if there is nothing in the dropdown that makes any sense for what they are trying to add.
I have the dropdown dynamically getting titles from the database. Unfortunately, this means that the first value in the dropdown list is not a default that says "Select an option." I don't know how to get the dropdown to have the first option listed as "Select" when the values are being pulled from the database. I can't add Select an option to the database so how would this even work?
What can I add to my codebehind that will allow the textbox to insert into the database if the dropdown list is not inserting anything? Right now I don't have any codebehind for the textbox but I do have the dropdown list inserting the correct information.
