I am having great difficulty that I can not solve and need help.Fill a DataTable with a sql statement that seeks accounts payable and accounts receivable overdue and wanted to show these accounts are grouped into a treeview format OutlookExpress.+ Accounts Payable - Account 1 - Account 2 - Count 3+ Accounts Receivable - Account 4 - Count 5 - Count 6Someone help me please.
Typically the OutlookExpress ViewStyle is used to present data relations that are recursive in nature, i.e., records that exist in a flat table, but where some records refer back to other ones. The classic example is Microsoft's OutlookExpress application (hence the name of the viewstyle), whereby newsgroup articles are presented with the first article as a root node, and each response to it as descendants of that first post. In that exampl, your post here would appear as a root node, and this response to it would appear as a child of that node.
You can get the view you describe above, but it would require that one of the rows in the table represents 'Accounts Payable', that is, would be actual data but a row that you somehow add in there manually. Frankly, however, I have no idea how you would get the data back to the database.
I created a dataTable (dtList) with the following structure:id - type - description - value-------------------------------------------------- ---------1 - R - C1 - 15.462 - R - C2 - 89.303 - D - C3 - 9.214 - R - C4 - 27.405 - D - C5 - 76.11Define the data source as dtLista treeview.So far so good, it appears right, but I need the treeview to group the data according to column type.Here is my problem.
WinTree doesn't have any grouping functionality. You could sort by a column, but it doesn't support the kind of grouping that Outlook does, for example. If that's what you need, then you may want to consider using UltraWinGrid, which has an OutlookGroupBy feature.
