Re: dynamic Filter ( Using multiple drop down list)

This code is not crashing anymore but it is not generating data anymore. 

 string s = "@segment = ";
                        //string @segment = "";
                        // get selected segments
                        int[] selectedsegments = lbSegments.GetSelectedIndices();
                        // add selected segments to s
                        for (int cnt = 0; cnt < selectedsegments.Length; cnt++)
                            {
                            // @segment += lbSegments.Items[selectedsegments[cnt]].Text + ",";
                            s += lbSegments.Items[selectedsegments[cnt]].Text + ",";
                            }
                        // display
                        //lbSegments.Text = @segment.Trim(',');
                        selectCommand.Parameters.AddWithValue("@campaignId", this.ddlCampaigns.SelectedValue);
                        selectCommand.Parameters.AddWithValue("@campaign", DBNull.Value);
                        selectCommand.Parameters.AddWithValue("@segment", s);
