Thank you. This is fixed in the latest update (not announced yet). It is regression WJ-7683.

Hi Frank.

Thanks. Works as expected!

Hi Alex,

On the 1 column scenario, I use the ListView as it is out of the box. I never took the trouble to investigate whether a 1 column DGV, hiding row headers and with some more tweaking (hide grid lines, smaller line height, etc) could be as easy to read as the ListView. It’s a question of “Why bother if ListView gives me exactly what I need?”

I understand a lot of people doesn’t use ListView at all and prefer to use DGV in all scenarios. One of the reasons is native ListView doesn’t support DataBinding. As I said earlier in this thread, I use a ListView version that supports Data Binding (btw VWG ListView also supports DataBinding). So I don’t face this problem. On the other hand, some people prefer to use DGV only when they must, arguing it’s slower than ListView. This might have been an issue when .NET 2.0 was released. Computer performance increased a lot in the last 10 years so I don’t believe this is an issue nowadays, except if you are loading thousands of rows.

Dear Tiago,

Thank you so much for taking the time to reply in such detail and for the useful links and your project. I’ll have to study it and I’ll get back to you.

For the moment, I understand that the most obvious (and fair) comparison of DataGridView with ListView is when ListView is is Detail mode.  So, in case 3, where you say that you’d use a 1-column ListView in Detail mode, why do you find the ListView provides superb readability compared to DataGridView? What is making the DGV less readable to you?

Thanks again,

Alex

That’s a tricky question…

First of all, lets put aside hierarchical data. Next, let’s presume both controls are data binding capable.

Now consider the need for a detail panel. If I have a master list, do I need a detail panel to show or edit my items?

DGV is kinda replacement for Excel.
I would prefer DataGridView to

1) Show tabular data (data organized in columns)

• you should use tabular data when objects have a lot of properties or
• you want to sort data using one or more columns or
• you want to filter data by one or more columns.

2) In place editing of objects with more than one property.

Provided all object properties fit comfortably on the available screen space (when your user doesn’t have to use the horizontal scroll bar), inline editing avoids the use of an editing panel.
Note – If you use a DGV as a master list, I presume you are showing more than a few properties and the DGV will be widish. In that case, most of the times the best location for the detail panel is below the DGV. This means te DGV can’t be very tall, and your users will have to use the scroll bar. If the DGV isn’t that wide, you can use a full height DGV on the left side, and put the detail panel on the right side of the DGV. This is an interesting design that opens a number of possibilities, depending on the specifics of your object. But that’s a bit besides the point.

ListView is file system manager-style interface with four view modes: LargeIcon, SmallIcon, List, and Detail.
I would definitely prefer ListView when

3) I need and editing panel anyway and the master list displays just 1 column (a few properties that can be put in a single string).

Note – For this scenario (say a list of user names), I would use the ListView in Detail mode. It has a very clean presentation (you can even hide grid lines) and provides superb readability. I presume I could use a full height ListView on the left end, with the editing panel on the right, possibly with… again, there are a lot of possibilities. And that’s besides the point.

4) I need the ability to show the list using icon view modes or list mode.

For hierarquical data, use tree like controls; ask google about

I attach a sample WindowForms ListView project that illustrates all view modes. I hope I can convert it to Wisej soon enough 🙂

Hi Luca,

I am trying your sample above (Wisej.CustomColumnEditor) but don’t see anything on the grid when I start editing. And I am getting an error as per attached image.

Thanks.

Hello everybody,

This is a general question, I believe more for you, Tiago, to answer, but it could be interesting to more people.

Since the days of VWG, I used to hear about the goodies of ListView, but I had failed to see in what way it is so different from DataGridView. So, I’d like to ask in which kind of scenarios do you favour ListView over DataGridView? Any examples from real life applications would be very much appreciated.

Best regards,
Alex

Hi Frank,

It is now working as expected.

Thanks.

Hi Frank,

I tested it and yes, system messages localization is now working in 1.2.76. Thank you very much!

Hi Robin,

please retry with the latest build (1.2.76).

Best regards
Frank

We have uploaded a new build that includes the following fixes and enhancements

For WJ-7681 you can take a look at the updated Localization sample to see how to localize system message boxes.

Hi Marcy,

This issue is related to WJ-7648 “Deleting multiple rows from a DGV removes the wrong rows on the client.” which was marked as fixed and I have now reopened. The issue is the order of deletion. The correct rows are deleted on the server, it’s the client update that is wrong depending whether you are deleting from the top or the bottom.

If you hit refresh you can see that the deleted rows are correct, it’s the update that is wrong. It will be fixed in the next update.

Thanks,

Luca

Glad to help.

I think we should add data binding to as many controls and properties as possible, and the ListView is the perfect candidate. It will be added after the release, I will get back to you directly about using your implementation.

Thanks!

Luca

Hi Luca,

I know WindowsForms’ ListView doesn’t support DataBinding. Will the Wisej’s ListView support DataBinding as VWG does? Personnaly I don’t care as I have a BoundListView that runs under Windows Forms (I sent you the code, along with the BoundTreeView) and I hope it will be quite easy to port to Wisej.
