From DropDown to MultiSelect

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.

Re: From DropDown to MultiSelect

I solved with solution by creating an function pass in a parameter and return the Guid.

Example function

public static Guid getProduct(string name)
{

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

DataSet1 dataset = mainForm.GetDataSet();

// Get distinct set of Families referenced in opportunity dataset

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

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

Guid aPro = Guid.Empty;

// Create list of region options

foreach (DataRow aPFRow in distinctAProductFamily.Rows)

{
if ((string)aPFRow["productfamilyname"] == name)

                {
                    aPro=(Guid)aPFRow["productfamily"];
                }
            }

return (aPro);

}

Thank you.
