Fill ComboBox From Table In Access
Aug 6, 2010I am creating a form for entering technical data about a part into an Access database. In the same form I have several ComboBoxs that need to have their lists filled from the same reference table in my database. I have a number and unit field for the twist and bending radius properties. I made the unit fields ComboBoxes and I am trying to bind them to referance table in my database called UnitsLength. The relevant structure is as follows....
Form: NewPartForm
Database: CableDataSet
Main Table: PartMechanical - with fields: TwistNom, TwistUnits, BendingRadiusNom, BendingRadiusUnits
Reference Table: UnitsLength - with fields: Unit, Shorthand, Conversion Factor
First tired the following settings....
Data Source: Other Data Sources > NewPartForm List Instances > CableDatase
Display Member: UnitsLength.Shorthand
Value Member: UnitsLength.Unit
SelectedValue: PartMechanicalBindingSource > [The associated unit field]
But the lists didn't populate.... Then I tried these settings
Data Source: UnitsLengthBindingSource
Display Member: Shorthand
Value Member: Unit
SelectedValue: PartMechanicalBindingSource > [The associated unit field]
But now every ComboBox displays the same value but still stores the data in the proper field... it just sets them all the same.
Fill Combobox With Database Query?
Apr 28, 2010I am having a problem with filling a combobox with unique values.Im not very good at vb either so I will explain what I have done so far.
1. I added a combobox to my form called Combobox1
2. I clicked the little triangle widget thing on the ComboBox1 set the dataset to MyDATASETDataSet1
3. Display Member: CurrencyCountry, Value Member: FCode, Selected Value = None
4. I fill MyDATASETDataSet1 when the form loads using:
PricesTableAdapter.ComboBoxQuery(CurrencY_DATABASEDataSet1.Prices)
ComboBoxQuery =
SELECT DISTINCT [CurrencyCountry], [FCode] FROM [Prices]
The form does not load, i get the error: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.If I replace ComboQuery with Fill Query (which is the default fill command) it displays results....but not unique results, i see the same items being repeated throughout the list in the combobox.I guess my questions are:
1. when you fill a dataset do you need to select all the fields when you are creating your query?
2. if i simply wanted to perform the following lookup:
SELECT DISTINCT [CurrencyCountry], [FCode] FROM [Prices]and set the combobox Display Member: CurrencyCountry, Value Member: FCode how would I do this in the code?
3. how can i change my query to display only unique values, distinct doesnt seem to be working?

Fill Other ComboBoxes DataSources When Another ComboBox Changes?
Sep 23, 2011I have a form that has three comboboxes in it, cbxStudy, cbxMethod, & cbxAnalyte. When I call the form I load a data table and use that table to fill the comboboxes. I want to assign a value to cbxStudy, then fill cbxMethod by filtering the data table using the value in cbxStudy, then fill cbxAnalyte by filtering the data table using the values in cbxStudy and cbxMethod.
This code keeps failing when the forms New constructor is called, but once the form is loaded the code works great. I indicated below where the code is failing. It's failing because Me.cbxStudy.SelectedValue is = {System.Data.DataRowView} when the constructor is called even though I set the SelectedValue myself.
Public Class frmSelectMethod
