delphi - Grouping items inside TListView object? -


I am trying to group items within the TListView object, but I find the class responsible for grouping the object I can not, neither am I able to do this within the document.

  • What is the class about grouping items within the TListView object, and how to use it properly?

Platform FireMonkey (Android / iOS) / Delphi X6

This property I believe is you talking about TListGroups , is a collection in which TListGroup items are provided in the Delphi document < / P>

Unfortunately, this is not only available in VCL and is not FMX, because the built-in functionality is a part of the Windows List View Control which can be found in the TListView Wrapped.

The closest you can get in FMX is using TListBox and a TListBoxGroupHeader which is included in the Multi-Device Tutorial A table view (Using ListBox component to display iOS and Android)) : 

  Process TForm1.FormCreate (Sender: Toubys); Var c: Four; I: integer; Buffer: string; Listbox item: TLITboxime; ListBoxGroupHeader: TListBoxGroupHeader; Start ListBox1.BegginUpdate; For C: = 'A' starts with 'Z' // Add 'Headset' ('A' to 'Z') in the list list box group header: = TListBoxGroupHeader.Create (ListBox1); ListBoxGroupHeader.Text: = UpperCase (C); ListBox1.AddObject (ListBoxGroupHeader); // I: Add items to the list from 1 to 3 ('A', 'A', 'AA', 'B', 'BB', 'BBB', 'C', ...) / Repeat StringOfChar Returns a string with a specified number of characters going. Buffer: = stringoff (c, i); // Just add items // ListBox1.Items.Add (buffer); // Or, you can automatically add items by ListLoxItem by creating an example of TListBoxItem: = TListBoxItem.Create (ListBox1); ListBoxItem.Text: = buffer; // (aNone = 0, a = 1, a decree = 2, aCheckmark = 3) ListBoxItem.ItemData.Accessory: = TListBoxItemData.TAccessory (i); ListBox1.AddObject (ListBoxItem); End; End; ListBox1.EndUpdate; End;

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
