GroupBy with multiple fields
Hi, How can do multiple group-by consolidation? As mentions in the docs that can be done, But I didn't find a way. For example suppose I wish to group by by both "Country" and "City": S:= TSummary.Create(nil); S.AddGroupBy(Data['Country']); S.AddGroupBy(Data['City']); S.AddMeasure( Data['City'], TAg...

Performance issues and a bug
I'm working with a TDataset that contains 100,000 records. I noticed some a performance issue and while resolving it I also noticed a bug. 1. I'm using TZMemTable (zeoslib 8.0) which is a in memory TDataset (i.e. all the records are loaded into the memory) 2. I noticed that every time the grid acces...

Grid view changes after sorting
To recreate:
1. The user scrolls vertically (to the right) and put into view a column that was not first visible
2. Then sorts by this column
The grid scrolls back back to the left (the sort is being maintained)
I'm using: windows 10, Lazarus 2.2.4, Grid 1.1

TeeGrid and tab
How can I prevent the "tab" key to move between cells?
I want to reserve "tab" and "shift+tab" to move the focus between the controls on the form. not within the grid itself.
Thanks.

Bug - Pasting into a cell while in readonly mode
Hi, I have a gird with ReadOnly set to true. While I tried to copy data from one of the cells I accidently pressed ctrl+v (paste) and got the following error: "Dataset is read-only" That should never happen, if the grid is in ReadOnly mode it should block any attempts to change the content from user...

Re: Bug/Usability Issue: Column with data renders as empty
Hi Marc,
Thank you, but that is a good solution when the application uses static queries. When the user defines its own query the *default* should not be blank. It gives the false impression that the field is null.
The default should me something like: {unprintable data...}
Thanks,
Yoni

Bug/Usability Issue: Column with data renders as empty
Hi, Please see the attached image for reference. The column "authors" in the database has a none standard type, but while in the standard grid the user *knows * it has some kind of value, In TeeGrid the user get to think that is has none. As it involves a postgressql database, I cannot send an examp...

Re: Usability Issue: Keyboard navigation doesn't put the column into view correctly
I suppose I didn't explain myself... You can see the issue I talked about in the example you prepared. Look at the "company" column on the first row , you never see the entire content of it. Only after the user leaves the column and moves to the "address" you see the rest of the name. but never its ...

Feature Request: OwnerDraw event in certain cases
Please enable user OwnerDraw event for the following situations: 1. Before any datasource is attached to the grid 2. When the datasource is attached but is *empty* 3. When data is being fetched from the server (so you can have "Loading..." text or animation) For example, see the difference for use c...

Re: Usability Issue: Keyboard navigation doesn't put the column into view correctly
Attached is a simple source code for a project that reproduce the problem.
You need to download sqlite3.dll and place it in the project's directory (due to size limit I couldn't upload it directly)

Re: Usability Issue: Keyboard navigation doesn't put the column into view correctly
Hi, I cannot find the TeeGrid_Themes_VCL. I do not own Delphi, so when I specify Lazarus it doesn't get installed (Lazarus has 2 demos installs that I cannot run, I'll open another issue regarding the demos). I'll prepare a small project that only uses the default components (I'm using ZEOS in the f...
