Filter grid with checked listbox

[David Botero]

Hello, I have a grid and a checked listbox, what I want to do is filter de grid by selecting/deselecting the listbox items, i had it working, but I don't know why it stopped working, this is the code:

private void fncGridData(){
        try
        {
            DataView dvDataView=new DataView();
            dvDataView = ((DataTable)Cache["Materials"]).DefaultView;
            if (lstSubcategories.CheckedItems.Count == lstSubcategories.Items.Count)
            {
                dvDataView.RowFilter = "";
            }
            else if(lstSubcategories.CheckedItems.Count==0){
                dvDataView.RowFilter = "id_sub_category=-1";
            }
            else {
                dvDataView.RowFilter = "id_sub_category IN (" + fncQueryComplement() + ")";
            }
            RadGrid1.DataSource = (DataTable)Cache["Materials"];
        }
        finally
        {
            SqlConnection.Close();
        }
    }

This code was exceuted on the ItemCheck property of the listbox, but then I made some changes to other parts of the code and it stopped working, why is this?

Regards.

Hi David,

Based on the supplied information, it is hard to determine what is causing this unwanted behavior. To further track the issue, it will be best if you open a formal support ticket, and send us a small working project, demonstrating your setup, and showing the unwanted behavior. We will debug it locally, and get back to you with more information on the matter.
