Find UserForm ComboBox Value & Transfer TextBox Data To Same Row

My question is, instead of deleting the row, how can I use the combobox to replace that row with the updated info rather than delete and resort? I have a combobox that selects names from a sheet, column A and populates itself on Userform activate/initalize. Using the Combobox to select a name, this code below populates all the fields on the form, various text and comboboxs.

When users hits the update button, it currently finds the row and deletes it, see second code example, but this reaks havoc on various parts of the program, I have to move the combobox and add name textbox's because when it deletes the row, the combobox takes on the next rowsource and then writes that info, rather than the info selected.

Private Sub ComboBox1_Change()
If bBlockEvents = True Then Exit Sub
If ComboBox1.Value = "" Then
Reset
bBlockEvents = True
ComboBox1.ListIndex = -1
bBlockEvents = False
Exit Sub
End If
userow = ComboBox1.ListIndex + 3
usercolumn = 1
If userow = "0" Then
ComboBox1.Value = ""
Reset
Else.......................
