What cell in the data grid was clicked?

[James Hurley]

The user clicks on a data grid cell.

What variables determine the row and column numbers of the cell?

And the text of the cell?

Thanks,

Jim Hurley

Re: What cell in the data grid was clicked?

It doesn't seem like the datagrid commands made it into the dictionary I have. 
I foraged around on the runrev website and found some info. You might find what 
you need on the following links. As a warning, I don't know jack about 
datagrids, just trying to be helpful.

Jim,

Each row in a Data Grid form/table and each column in a Data Grid  
table have custom properties that help you determine this information.  
Note that you use names to reference columns rather than numbers  
however. These properties include the dgLine or dgIndex and the  
dgColumn.


I just updated the "How Do I Get Data Associated With a Row or  
Column?" lesson in the manual to provide some more useful examples.


How Do I Get Data Associated With a Row or Column?: 



And the text of the cell?


The lesson also shows how to get the value associated with a cell  
using GetDataOfIndex. Look at the very last step in the lesson.

One other lesson you might want to look at discusses how to define  
your own mouseDown handlers in a Data Grid. You have to make sure that  
the Data Grid is allowed to process the mouseDown message before your  
code does.

Trevor,

Thanks once again. The  GetDataOfIndex  was the function I needed.

Unfortunately I am trying to learn data grids the way I learned the  
rest of RunRev, by applying the "Necessity is the mother of discovery"  
method.
There are too many bits and pieces of the data grid control for this.  
I need to exercise the discipline to go through your excellent  
tutorials. Sounds like a new year's resolution to me.


Regards,

Jim Hurley
