Refresh On Combobox Update

[tommyf]

I have a combobox bound to a dataset using databinding.

 

When the form loads it popultes the rest of the text boxes with the relevant information from the first record.

 

What I can't seem to find out what to do is when I change the record in the combobox the rest of the text boxes change to.

 

Do I have to use the position of the record as the key to all this.

you can use the selectedindexchanged event, and use the selectedindex property to retrieve the desired row from the dataset

binding data

 

After establishing the complex binding (to the combobox) and simple binding (to the text boxes), setting the BindingContext of the form establishes which record is displayed on the form. Set it equal to the selectedindex of the combobox.

 

example:

cmbEmployeeName.DataSource = dataset1.Tables("Employees") 
cmbEmployeeName.DisplayMember = "Name"



lblEmployeeName.DataBindings.Add("text", dataset1, "Employees.Name")
lblPhone.DataBindings.Add("text", dataset1, "Employees.Phone")

then, in the selectedindexchanged event of the combobox, reset the bindingcontext:

   Private Sub cmbEmployeeName_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmbEmployeeName.SelectedIndexChanged
  
       Me.BindingContex(dataset1, "Employees").Position=cmbEmployeeName.SelectedIndex
    
   End Sub
