I am using Winform and MySQL in my project.
When I try to get the ComboBox Vales in Different Method I saw the ComboBox Selected Text Propriety is empty.
Why it is empty?.
And Please say the Difference b/w ComboBox Selected Item and Selected text?.
SelectedItem is the combobox item which is selected by the user, whereas the SelectedText property contains the possible selected part of the item text.
In your example "CITY" is the string representation of the selected item. If the user only selects "IT" in the text area of the combobox (if possible) this is the value of SelectedText.

I have a Sales form that contains the ItemSoldID field.
It was difficult to write itemSoldID for every item by memory because new items are frequently added and the list has reached to More than 100 Items. It is difficult to remember id number for every item.
I want to make a combo box. That should Choose Item Name in the box and the ItemSoldID gets autofilled based on the Selection.
I tried dlookup on gotfocus property of ItemSoldID but i am new to access. Something is wrong.
Please Help............
I have a column in my database that is set to memo. I am trying to view the data in a textbox.
I have enabled new line in field from the Enter Key Behaviour property but all the data from the record is now showing - What am I missing?
The data is being pulled from a list box, example code below:
Textbox1 = listbox.column(1)
Thanks in advance
This has nothing to do with the EnterKeyBehavior property of the text box.

Row Source
A Memo field in the Row Source of a combo box or list box will
truncate.
Don't use memo fields in combos or list boxes.
You'll need a different method to load the text box, e.g. read the ID from the listbox and use DLookup().
I have three combo box controls(MFG, Code, and GrpID) in my VBA access form. Once the user selects an option from the first combo box (MFG), rest of combo boxes give me available options. But I need to do some validation i.e. what if the user decided to change the value of first combo box? The values of rest combo box should be cleared. All I need to do is once the first combo box is changed the second and third combo box need to be cleared out or at least set to focus on them so that users will realize that they can't use old values as first value is cleared in the first combo box. I added a code block 'AfterUpdate for first combo box as shown below:
Private Sub MFG_AfterUpdate()
Code.Value = " "
GrpID.Value = 0
End Sub
The problem after writing above code is: they don't get empty until they(Code and GrpID) get clicked. In other words, I need to click them to empty them every time I change the value of MFG. Can anyone direct me how do I clear them or at least focus them?
Set the combo to null to wipe any displayed value in them;
Me.Code = Null
Me.GrpID = Null
This assumes your combo controls are called the same as your field names.
Edit for clarity: Including the Me. makes sure your are changing the form control values. If your field names are the same as the controls then Access will change the underlying field values, and as you have discovered on your form these aren't reflected until you click in that fields bound control.
I have a form in Access with a textbox and a combobox, and need to filter the combobox dropdown options using the value in the textbox. The textbox contains a Category for the choices.
I've done this using
SELECT Options.Choice
FROM Options
WHERE (((Options.Category)=[forms]![FormName]![Text10].Value));
Is there a way to refer to the value in Text10 without explicitly referring to FormName?
I'll need to duplicate this form within the same Access file and changing all combobox row sources for a new form is not feasible. I can't hard code the Category value for each combobox because there are many comboboxes per form, and the value in the textbox will be different on every form. Any help is appreciated.
You can refer to whatever form you're currently on in Access using Screen.ActiveForm. So in your case you'd have:
SELECT Options.Choice
FROM Options
WHERE (((Options.Category)=[Screen].[ActiveForm]![Text10].Value));
As long as the field name stays constant this should work.
When i saw the Combo box Propriety Selected item and text Returns Same value in WinForms.
So What is Difference in between,.. Where i use ComboBox.SelectedItem ?
and Where i use ComboBox.Text?
combobox.text is always a string, combobox.selectedItem is an object
You can put any object to the ComboBox control.
SelectedItem will return this object.
Text will return string representation of the SelectedItem when ComboBoxStyle = DropDownList ( text portion is not editable), the result may be like this - SelectedItem.ToString().
Find more information here - ComboBox Class.
In your case, if you add strings into the ComboBox.Items, then there is no difference what to use SelectedItem or Text.
