I tried to bludgeon it into submission by writing: and got appropriately vulgar results.
Public Class Form1 Private Builder As New OleDb.OleDbConnectionStringBuilder With ' Use original LINQ above and append Where via Lambda Query = Query.Where(Function(c) c.Country = cboCountries.Text) DataGridView1.DataSource = Query.

#VISUAL BASIC DATA TABLE TO COMBOBOX HOW TO#
How to append parts to the select statement in regards to the WHERE clause, this is one. Select FirstName as the Display Member and Value Member. Do the following query to create a table in the database that you have created. I have a method which binds Datatable to the combobox. After that, right click the database, then select New Database and name it dbperson 3. //define DataTable DataTable dt new DataTable(dataTable) dt.Columns.Add(Id, typeof(int)) dt.Columns. A new binding source Table1BindingSource will be created and selected itself. HI, I have a ComboBox in my WindowsForm(Vb 2005). Select the option Use Data Bound Items from the ComboBox Tasks: Select Table1 for the Data Source property. Granted there are many different ideas on Place a new ComboBox1 and Label1 to the project Form Design. In the Button1 click event we check the user selections and build a SQL statement followed by executing the statement against the backend database. The example below is simple, provideĭistinct values for two columns in a table in the form load event. One method would be to load ComboBox controls with distinct values for specific columns from the database table you want to query against then have the user select from these ComboBox controls and build a SQL statement. dim mycon as new sqlconnection('connectionstring') mycon.open() dim da as new sqldataadapter('select from table1',mycon) dim dt as datatable da.fill(dt) combobox1.datasource dt combobox.displaymember 'field name you want to show ' combobox.
