Question

C# -- Filling a "ComboBox"

Asked by: finance_teacher

Where can I change this ComboBox to use my
new "Order By FMENTITYNAME" FILL method and
still have the other ComboBox use the
other "Order By Nothing" FILL ?
-----------------------------------------------------------------------
SETUP - General

1.      create new APP
2.      Data, Add DataSource, select "FMENTITY" table
3.      drop two "ComboBoxes" onto Form1 and do the below for both "ComboBoxes"
§      check "Use Data Bound Items"
§      DataSource = FMENTITY
§      DisplayMember = FMENTITYNAME
§      ValueMember = FMENTITYOBJECTID
§      don't select "Add Query" since this just puts a "FillByToolStrip" onto Form1
4.      run APP
5.      "ComboBoxes" displays items, but they are not in "ALPHA" order
-----------------------------------------------------------------------
SETUP -- Alpha Order

1.      open DataSet1.xsd
2.      rightClick FMENTITYTableAdapter
3.      leftClick AddQuery
4.      Next, Next, add "Order By FMENTITYNAME", Next, Name = "FillBy_Sort_FMENTITYNAME" &  "GetBy_Sort_FMENTITYNAME"
5.      reopen Form1
6.      click first ComboBox
7.      PROPERTIES window

creata seperate query IN your database. Open THIS as your datasource for the one combobox and the other directly to FMENTITY

You can use the built in controls for this.

Add a Bindingsource to your form. Select the datasource property of the binding source. Click Add a project datasource and finish the setting up of the binding source. A dataset should have been created.

on you combobox datasource property select the table that you require under the bindingsource that you added at the beginning. Set the display and value members. A knew binding source was created

select a datasource for the other combo in the same way as the first one.
Another binding source was generated for you and you can set that bindings sources sort property as follows "ColumName asc" or "ColumnNameDesc".

Eventhough this is functional it creates a lot of overhead.
