Fixed Bands to help you present data to users with efficiency. I hate to tell them that all I have to do is drop a grid in place and its done, got to keep some of suiye mystery going. I can’t remember what the problem was with rDBGrid.

Experience with TMS Component Pack or ExpressQuantumGrid Suite –

I can’t remember what the problem was with rDBGrid. I am in the middle of a major corporate database front end development effort and am using the ExpressGrid and MemData heavily. I ended up looking in depth at two alternatives: Essentially then you have a loaded stringgrid not a DBGrid. I will now be upgrading to Devexpress.

They are shown in toolbox choose item option exprewsquantumgrid, as COM component, not as. It does install the D edition on the same box. I see they both have DB-aware components, so I’m wondering: Only a windows worth of data is in memory at any given time most decent engines will also have a buffer so there’s a bit more loaded as well and initial access is pretty much instantaneous.


At that point the grid has all the data loaded. 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.

Preparing Application With QuantumGrid Controls for TestComplete

Bart Greyson replied on Jul But price isn’t everything; Devexpress has comprehensive documentation and context sensitive help. Can any body suggest alternatives and comment on their experience with these?

You may want to look at X-DBGrid http: Personally I had significant problems with their DBGrid and eventually swapped it out. Unfortunately, though, a version for use with Excel format files. For more rxpressquantumgrid, see http: It hasn’t been anywhere near as a productive outcome as I had hoped.

Everything else I wanted it expressquantkmgrid do. On the other hand if you link a table to a DBGrid and the appropriate indices are there its a lot faster to change the index rather than resort the data. NET Component Suite to use? If you allow, your users can continue to edit records even if data has been grouped by one or more columns.

Even using it in bound mode can, with a number of events especially the display expresssquantumgrid ones mean that you have to somehow sync the display with the dataset to do anything.


Runtime Summaries for Grouped Nodes so you can summarize information and eliminate the need to write complex banded reports using a traditional report writer. But I’m not sure what the difference is between the so called stringgrid and the dbgrid Look and Feel – From screen painting to scroll bars I still get a lot of access violations using the TMS components, but that is probably also down to me.

Banded Columns – The QuantumGrid Suite allows you to create banded columns to enhance the display of information to end-users at runtime.

Developer Tools

William Meyer replied on Jul After you have performed the mentioned steps, TestComplete will be able to access internal objects, methods and properties and recognize Epxressquantumgrid controls in expressquantumfrid application under test. Especially when compared to the TMS approach which requires an intermediary, non-visible, link component between the editor VLC and the dbgrid.

This includes an intelligent scroll bar, and the two display styles using the LookandFeel Property Flat or Standard. In this case, you can handle grid controls in black-box mode, by simulating mouse clicks and keystrokes.
