Experience with TMS Component Pack or ExpressQuantumGrid Suite –

I see they both have DB-aware components, so I’m wondering: They are shown in toolbox choose item optionas COM component, not as. This includes an intelligent scroll bar, and the two display styles using the LookandFeel Property Flat or Standard. This means that you own the ExpressQuantumGrid xepressquantumgrid with full source code. Please download the trial version http: Even using it in bound mode can, with a number of events especially the display based ones mean that you have to somehow sync the display with the dataset to do anything.

Borland had their own vision. Ultimately, the grid is designed to allow you to do what you want and not to be at the mercy of someone else. The learning curve is short and quick. Hi Roy, I don’t mind having to include ID columns in the dataset tied to the grid, as I was used to doing that with expressqjantumgrid dbgrid from DevExpress too otherwise it could sometimes not select a single row for example as they were not unique anymore. Essentially then you have a loaded stringgrid not a DBGrid.

And expeessquantumgrid as important, sorting can be done against one or more columns in the grid, be it a standard column or a calculated one. File Exploration is Disabled We’re sorry, but errors in the uploaded zip file prevent it from being explored. I can’t remember what the problem was with rDBGrid.

Unfortunately, both lacked some feature that I regard as critical ie I’m doing it now and want to keep on doing it. I’ve spent a lot of time looking at the various grids out there and there are more based on TStringGrid or a company’s equivalent than on DBGrid.


A couple of minor components don’t work at all in XE2, complaining of missing resource files. Bart Looking back at your original post you said “I especially want the DB-aware grid component to be powerful enough” but didn’t expand on what that means. Unless you run the grid exprezsquantumgrid unbound mode ie load all the data into the grid there are conflicts between DB operation a nd normal stringgrid operation plus you have to load the datasets ID columns even if you don’t want to display them because ultimately that’s the only way of keeping things in sync.

I’d try them both as a trial, but I don’t expresssquantumgrid the time to do so in a decent way. Arguments are fiercely debated in both camps. Exprressquantumgrid the way you draw the header, expressquantumgtid the spacing of the columns using the AutoWidth feature.

Needless to say, my end users are amazed at the functionality we are providing them. To meet the demands of your end-users. XLSX has been promised for years now but just never arrives and I have reached a stage where I just have to update some of my software. Just set two properties at design time or runtime and you are on your way to enabling an extremely powerful data viewing and manipulation metaphor inside your applications.

The error generated by the Zip attachment is: Using data aware editor components in the grid is easier and more intuitive in Devexpress, IMO. Operations on the data are generally faster with it all loaded into memor y.

I can’t remember what the problem was with rDBGrid. Even using it in bound mode can, with a number of events especially the display based ones mean that you have to somehow sync the display with the dataset to do anything. Pierre Duparte replied on Jul A DBGrid simply provides a scrolling window into the table. I especially want the DB-aware grid component to be powerful enough, but I need good DB-aware edit controls too.


To include debug information in QuantumGrid controls, do the following: About Suggest a fix License Print. Personally I had significant problems with their DBGrid and eventually swapped it out. I would really like to go to the DevExpress package, but I just saw they removed the ability to buy seperate packages.

At that point the grid has all the data loaded. Footer Display to allow you to summarize data such as Sum, Count, Avg, Min and Max, as well as a custom draw capability.

Runtime Row Resizing so your users can adjust the height of QuantumGrid rows to meet their specific needs. You can specify expfessquantumgrid design time the columns to include both within the ExpressQuantumGrid as well as those available as part of the runtime column selector window.

Developer Tools

exprsssquantumgrid Since I only have experience with the DevExpress grid, and I don’t have the time to test other ones, and since the DevExpress one has been recommended often, I think I’ll go for this one For me the expressquatumgrid problem with the stringgrid based DBGrid was the fact that the display and underlying dataset can be out of sync, and if you use it in unbound mode it WILL be out of sync.

Everything else I wanted it could do.

For the TMS grid you could set up the datasource for the grid, open the dataset with PageMode set then once the data is loaded set it to False, and preferably set the datasouce to nil. However, I am sick of re-installing XE2 so have given up on that one. Hi all, I’d like to start using some DB-aware components in the new applications I’m about to write.
