CheckedListBox1.DataSource = Me.BindingSource1

        CheckedListBox1.DisplayMember = Me.DataSet1.ITEM.ITM_TYPEColumn.ToString()


I have created the Bindingsource and dataset1 using visual studio 2005 tools, no hardcoding. I dont know how to hardcode this into my code.

When starting the program all i get inside the checked listbox is system.data.DataViewManagerListItemTypeDescriptor

Im connecting to a oracle database, and i dont understand why i dont get the Item types in the checked listbox when i start program :/

Please help!!

CheckedListBox1.DataTextField = "ColumnName"
 CheckedListBox1.DataValueField = "ColumnName"

Replace column name with the names of the columns you want displayed in the checked listbox.

Basically, you need to tell it what columns to use.

try this

       With CheckedListBox1

                .DisplayMember = "ITM_TYPEColumn"
                .ValueMember = "ITM_TYPEColumn"
                .DataSource = DataSet1.Tables("ITEM")

     End With

ok the error seemed to be that my form didnt have a tableadapter to it. I got this to show up when added a datagrid view and just deleted it after.

The code i had worked fine too :)

But then another question you might know

i need two lines in the checkedlistbox, like "Customer_first name" and on the same line in the checkbox "customer_lastname"

how can i do this?

ive tried to CheckedListBox1.DisplayMember = Me.DataSet1.ITEM.ITM_TYPEColumn.ToString() & Me.DataSet1.ITEM.ITM_TYPEColumn.ToString()

without any luck, then the "error system.data.DataRowView" appears inside the checkbox when trying this

The easiest way I have found to do this is in the query/stored Proc.  For example:
Select Name, Company, Name + '-'+Company and Name_Company...

i resolved it by using        


Dim drv As DataRow
Dim rows As DataRowCollection = Dataset.customer.Rows

        For Each drv In rows
            Me.checklistbox.Items.Add(drv(2).ToString() + " " + drv(1).ToString() + " " + drv(3).ToString())
        Next
