Dear All,

When i am using combo box, my skeleton code work fine as this:-

Boolean filterByProductFamily = false;           

Guid productFamily = Guid.Empty;           

if (tscboProductFamily.ComboBox.SelectedValue != null)  {

                productFamily = (Guid)tscboProductFamily.ComboBox.SelectedValue;

                filterByProductFamily = (productFamily !=null && productFamily != Guid.Empty) ? true : false; 
}

productFamily  will stored the Guid

But when i try to change to multiselect as below, i having problem on Guid, Please advise. My skeleton code not completed as below:-

foreach (ToolStripMenuItem item in tsddbSegment.DropDown.Items) {               

if (item.Checked == true)
{
    productFamily = (Guid)item.Text;   //I stuck on this portion. How can i get Guid instead of value string. It maybe can call from Find segment method  at helpers.cs file. But i dono how to call it & return into Guid.
    filterByProductFamily = (productFamily !=null && productFamily != Guid.Empty) ? true : false;      }
}

Helpers.cs

 //  Return dataset of options          

public static List<SegmentItem> GetChoices()

{             

//  Establish reference to dataset              

frmMain mainForm = (frmMain)Application.OpenForms["frmMain"];              

DataSet1 dataset = mainForm.GetDataSet();               

//  Clear down existing list

possibleChoices.Clear();               

//  Add option 'All'

possibleChoices.Add(new SegmentItem("(All)"));               

//  Get distinct set of account managers refrenced in opportunity dataset               

DataView tempView = new DataView(dataset.OpportunityElement, null, "productfamilyname", DataViewRowState.CurrentRows);               

DataTable distinctSegments = tempView.ToTable(true, new string[] { "productfamilyname" });

//  Quit now if no account managers               

if (distinctSegments.Rows.Count == 0)

 {                 

    return possibleChoices;

}

//  Create list of account manager options               

foreach (DataRow segmentRow in distinctSegments.Rows)

{                       

        SegmentItem segmentItem =     new SegmentItem((string)segmentRow["productfamilyname"]);

         possibleChoices.Add(segmentItem);

}              

return possibleChoices;

 }         

//  Find segment method          

public static SegmentItem Find(String optionName)

 {               

      return possibleChoices.Find(delegate(SegmentItem option) { return option.Name == optionName; });

            }

        }

Please Advise.

Thank you.
