[RESOLVED] text properties read only

What this error message mean?How to solve it?My combo box style is dropdownlist

Combo1.Text = .Fields("Negeri").Value

When comnbo is drop down list, it acts much like a list box. One way to around this to make sure the value you are assigning is already in the list.
try something like this

Code:

---

Combo1.AddItem  .Fields("Negeri").Value
Combo1.Text = .Fields("Negeri").Value

---

But you may have to check whether item exists before you add it up
:wave:

This is another approach. You capture the error and add it before setting text to the combo. But this way, you wont have duplicates in the combo box. If the text is there in the combo, the text will be set to it. Otherwise, its addded to the list and then Text is set.

eg:

Code:

---

Option Explicit

Private Sub Form_Load()
    Combo1.AddItem "Test1"
    Combo1.AddItem "Test2"
    Combo1.AddItem "Test3"
    Combo1.AddItem "Test4"
   
   
End Sub

Private Sub Text1_KeyPress(KeyAscii As Integer)
  On Error GoTo Text1_KeyPress_Error

   
   
    If KeyAscii = vbKeyReturn Then
        Combo1.Text = Text1.Text
    End If
   
   


  Exit Sub

Text1_KeyPress_Error:
    If Err.Number = 383 Then
        If Len(Trim(Text1.Text)) > 0 Then
            Combo1.AddItem Text1.Text
            Combo1.Text = Text1.Text
        End If
    Else
        MsgBox "Error " & Err.Number & " (" & Err.Description & ") "
       
    End If
   
End Sub

---

You will need a Text Box(Text1) and Combo box(Combo1) to test this.
Type something in the Text Box and press enter to work it out.

:wave:

EDIT: Changed code: Trim and Len switched

Actually I want to update the record.

The current record doen't have this value. So When I push edit button, I want to update the record by choose the value in the dropdownlist and insert this new value.

Where do you want to update the record ? In DB or combo box?
Anyway, the solution is for the error you have mentioned here. Try to change the code in Post #3 to suit your need. the Error handler part specially.
