Populate Textbox Based On ComboBox Selection Not Using Databinding
Apr 27, 2010I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:
frm1:
Public Class frmLocations
Dim conn As New SqlConnection("Data Source=f03d3s-dev01; Initial Catalog=dos_track;User Id=vbuser; Password=tran3;")
Dim depot_refnbr As Integer
Private Sub frmLocation_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
conn.Open()
[Code] .....
What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.

View 20 RepliesVS 2010 Populate Textbox With Excel Data Based On Combobox Selection?
Nov 29, 2011Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.
What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

Change List Of Combobox A Based On Item Chosen From Combobox B?
Jun 17, 2011I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.

ASP.Net Auto-populate Field Based On Other Fields?
Nov 15, 2010how i can implement below requirement using asp.net and vb.net.I have three fields in a form which are filled by users. Based on these three values, i need to auto-populate the 4th field.I have planned to implement this in the following way.Write a separate class file with a function to calculate the possible values for the 4th fields based on 1st 3 inputs. This function can return some where between 1-10 values. So I've decided to use drop-down for 4th field, and allow users to select the appropriate value.Call the above function in onchange function of 3rd field and take and use the return values to populate the 4th field. I'm planning to get the return values in array field.(Does this need a post back?)
