Re: Listbox name edit Dave Kreskowiak16-Jan-07 9:22 Dave Kreskowiak 16-Jan-07 9:22  Uhhh, no. You'll have to remove the item from the ListBox and re-add it. Your other alternative is to create a typed dataset, load your data into that, then bind the ListBox to the dataset. If you do that, then any changes to you make should be updated in the ListBox when they're made. Dave Kreskowiak Microsoft MVP - Visual Basic Validate All controls on form priya_p23315-Jan-07 23:09 priya_p233 15-Jan-07 23:09  hi, i wrote following code to validate my all controls on form. it is working well but when i run my project & for testing purpose i leave the textbox as it is following code executed & showing appropriate message but it is validating controls randomly....& i wnt that it should validate control in a sequence ( e.g. employeeid ,empname,designation......etc). i have given tabindex to all controls in sequence though it is validating controls in random manner Wht shuld i do?? Is there anyone who will solve my problem???? Public Function Validate_Ctrl(ByVal sender As Form) As Boolean For Each obj In sender.Controls If TypeOf obj Is TextBox Then If obj.Name = "txtSearch1" Or obj.Name = "txtSearch2" Or (TypeOf obj Is CheckBox) Then Continue For If obj.Text = "" Then MsgBox("Please Enter Values In " + obj.Name, MsgBoxStyle.Exclamation + MsgBoxStyle.OkOnly, obj.Name + " Validation") obj.Focus() Validate_Ctrl = False Exit Function End If End If Next Validate_Ctrl = True End Function priya Re: Validate All controls on form shreekar16-Jan-07 1:03 shreekar 16-Jan-07 1:03  As far as I know, the for each loop will visit the controls not according to tab index, but something else. A cumbersome method can be to load all the controls in an array and then sort them based on their tab index and then apply the validations on them. A simpler method might be to use ErrorProvider and the validate events for a better control over validation (This applies only in .Net 2.0) - so if you are using VB 6, ignore this part.

Sounds more like the former, but either way, the way to do this is well documented online, if you're not willing to do some research and start your project, you're on your own.  If you're willing to give it a go, and ask specific questions when you get stuck, we're here to help.
