I have now tested MultiSelect == true in DAItemDialog with version 5.23.1162.1, and it works as expected. I have not tested version 5.21. Can you switch to 5.23 please (if you are a licensed user, then version 5.23 needs a different key file, but you can obtain it from us free of charge in this case).

While making the test first time, I have, however, fallen myself into a trap: Be aware that in a multi-selection mode of DAItemDialog, the items that are considered select in the dialog need to appear in the bottom list of the dialog. It is not sufficient to select (highlight) them in the list view on the right side. You have to press the button with the down arrow, to make them appear in the bottom list. This design exists to allow selection of items from different branches in the tree. I have marked up the UI elements in the picture below.

Can you please provide the full version/build? Right-click on one of the QuickOPC assemblies, select Properties, and find the version on the Details tab.

Thank you

(a copy of the code from the previous post:)

Code:

DAItemDialog dlg = new DAItemDialog();
dlg.MultiSelect = String.IsNullOrEmpty( item.Name ); // MultiSelect if name of // item not specified yet.
dlg.ServerDescriptor.MachineName = server.MachineName;
dlg.ServerDescriptor.ServerClass = server.ServerClass;
if ( dlg.ShowDialog( this.ParentLine.ViewControl ) == DialogResult.OK )
{
    int i = 0;
    foreach ( DANodeElement element in dlg.NodeElements )
    {
        if ( i == 0 )
        {
            if ( element.IsItem )
            {
                item.ItemID = element.ItemId;
                if ( String.IsNullOrEmpty( item.Name ) )
                {
                    item.Name = element.Name;
                }
                short vtValue = (short) m_instance.OPCClient.GetPropertyValue(
                    server.MachineName,
                    server.ServerClass,
                    item.ItemID,
                    DAPropertyId.DataType );
                item.OPCDataType = ItemData.ToOPCValueType( vtValue );
            }
            else
            {
            }
        }
        else
        {
            // Add new item to my list
            if ( element.IsItem )
            {
                ItemData it = new ItemData( item.ParentObject );
                it.Name = element.Name;
                it.ItemID = element.ItemId;
                this.ItemsList.Insert( this.ItemsList.IndexOf( item ) + i, it );
            }
        }
        i++;
    }
}

DAItemDialog returns nothing when using MultiSelect was created by Jan

Hi.

I'm trying to let the user select more than one element in the DAItemDialog.
But when I select more than one item the NodeElements property is an empty list.

Any idea what's wrong?

Im using QuickOPC 5.2.
