Default Applying Multiple Selected Values to a Listbox

Hi All

I wonder if anyone can help provide a little guidance...

I have created a listbox that is populated using data from a SQL Server table. I have another table which is used for the selectedvalue property of my ListBox.

I seem to be having a problem with applying the selectedvalue as my code doesn't seem to let me apply more than one selected value though my listbox's ListSelectionMode is set to Multiple.

I think the problem is more to do with my logic applying the selected values for the listbox...

Say that I have already populated my listbox and have collected the data for the selectedvalue items, which are stored within a dataset called GenreTable... the code below is where I try to apply it to the selectedvalue property...

Dim i As Integer
For i = 0 To GenreTable.Tables("reporttbl").Rows.Count - 1
                ListGenre.SelectedValue = GenreTable.Tables("reporttbl").Rows(i)("genreID").ToString()
What it is doing is only applying the selected value of the last row item within my dataset.

Many thanks in advance

OK, after a sleepless night at the PC I have found an answer...

Selectedindex, selectedvalue and selecteditem do not work in Multiple selection mode. The following code works though...

           Dim i As Integer
            For i = 0 To GenreTable.Tables("reporttbl").Rows.Count - 1
                ListGenre.Items.FindByValue(GenreTable.Tables("rep orttbl").Rows(i)("genreID").ToString()).Selected = True
