Hai,

I have a listbox control that having multiple selections.It is populating the values from sql table.In the below code "lstPrimaryImpactedArea" is listbox name.If we select multiple items it should be inserted into sql table.It is working in UI.But if we use dataaccesslayer how we can solve this.

<tr>
              <td align="right">


                <asp:Label ID="lblPrimaryImpactedArea" runat="server" Text="Primary Impact Area"></asp:Label>
              </td>
              <td>
                 <asp:ListBox ID="lstPrimaryImpactedArea" runat="server" SelectionMode="Multiple">

                  </asp:ListBox>
              </td>

          </tr>

foreach (ListItem item in lstPrimaryImpactedArea.Items)
       {

           if (item.Selected)
           {

               try
               {
                   lblMessage.Text = lblMessage.Text  + item.Text+",";
                   cmd.Parameters[
"@primaryimpactedarea"].Value = lblMessage.Text;
                  // string s;
                  // string str = item.Text + "," ;
                  // cmd.Parameters[
                  //  "@primaryimpactedarea"].Value = str;


               }
               catch (Exception ex)
               {

               }
           }
       }

Thanks in advance

[EDIT - Data Access Layer Code]

C#

SqlCommand dCmd = new SqlCommand("InsertBugsdata", conn);
            dCmd.CommandType = CommandType.StoredProcedure;
            try
            {
                dCmd.Parameters.AddWithValue("@bugnumber", bugs.BugNumber);
                dCmd.Parameters.AddWithValue("@publishtopartner", bugs.PublishToPartner);
                dCmd.Parameters.AddWithValue("@impactscale", bugs.ImpactScale);
                dCmd.Parameters.AddWithValue("@primaryimpactedarea", bugs.PrimaryImpactedArea);
                dCmd.Parameters.AddWithValue("@secondaryimpactedarea", bugs.SecondaryImpactedArea);
                dCmd.Parameters.AddWithValue("@impactedentity", bugs.ImpactedEntity);
                dCmd.Parameters.AddWithValue("@impacttype", bugs.ImpactType);
                dCmd.Parameters.AddWithValue("@percentimpact", bugs.PercentImpact);
                dCmd.Parameters.AddWithValue("@title", bugs.Title);
                dCmd.Parameters.AddWithValue("@description", bugs.Description);
                dCmd.Parameters.AddWithValue("@defectdiscovered", bugs.DefectDiscovered);
                dCmd.Parameters.AddWithValue("@eta", bugs.ETA);
                dCmd.Parameters.AddWithValue("@defectstatus", bugs.DefectStatus);
                dCmd.Parameters.AddWithValue("@defectstatusdetails", bugs.DefectStatusDetails);
                dCmd.Parameters.AddWithValue("@defectclosetime", bugs.DefectCloseTime);
              
                return dCmd.ExecuteNonQuery();
            }
            catch
            {
                throw;
            }
            finally
            {
                dCmd.Dispose();
                conn.Close();
                conn.Dispose();
            }

Hi Dude,
i have made a sample code,u can use this as reference to fix ur issue..

private void savedata()
       {
           BusinessLayer objBusiness = new BusinessLayer();
           int[] arySelectedItems = lstPrimaryImpactedArea.GetSelectedIndices();
           for (int i = 0; i < arySelectedItems.Length; i++)
           {
             string text =  lstPrimaryImpactedArea.Items[arySelectedItems[i]].Text;
             objBusiness.SaveData(text);

           }
       }

       protected void btn_Click(object sender, EventArgs e)
       {
           savedata();
       }
   }

   public class BusinessLayer
   {
       DataLayer objDataLayer;
       public void SaveData(string data)
       {
           objDataLayer = new DataLayer();
           objDataLayer.SaveData(data);
       }
   }
   public class DataLayer
   {
       public void SaveData(string data)
       {
           // write ur ado code to save the data in the database
       }
   }
