Add a Drop down menu / Combo Box into a specified cell of a multi column lsit box

[smercurio_fc]

Your solution is based on a completely different premise, so you're trying to compare a watermelon to a peach. Your premise is that each element is a dropdown. Well, this is a trivial and obvious solution - use an array of dropdowns. The original premise is to use a multicolumn listbox or table that would behave like a DataGrid in which specific columns (and only those columns) are dropdowns. Totally different beast.

Like I said the other solution posted on this thread takes you through gyrations..... Attached you will find a simpler way of getting this done...Yes, 1 out of many ways to do this....

Basically, single click to edit the Table cell, double click to use the pop down menu... You can edit as you see fit cus it rough cut.... go ahead comment away, I've seen this done b4, yea its not new...

What exactly do you consider a "gyration"? The VI in reply #6 suffers from relying on constants rather than picking up this information directly from the control. Other than that I see no "gyrations". The solution that Eugen had started to put together seems fairly straightforward to me as well, as it relies on the control itself.

Here's a sample, NI "style" of coding... I have to check the rule book. And this is not all either. I do believe a LAVA contributor mentioned "complex" or to that liking

FYI

There is an invoke node method available to help translate clicks to cells (which I am not sure would help here but it's worth sharing )

Indeed, and that's exactly what I meant in my statement

However, the VI that Eugen had started to put together still seems fairly straightforward to me, as it does just that, and is a better starting solution that the one posted in reply # 8, since using the Edit Pos places the dropdown's top-left corner where the user double-clicked, which is in the wrong place. Also, requiring the user to double-click seems counterintuitive to me. But perhaps I'm just old-fashioned.

This is precisely what I've already done (use Invoke node), the VI is posted above, see the attached pic of the BD. Open it and have a look at the Invoke node. Not the only way to do either...

Ya the reply from #6 seems foolish stuff. But at the end I still prefer TSPopup.Lookup.vi, contributed from LAVA. Thanks to JDave.

By TSPopup.Lookup.vi, just feed in current coordinate and control reference, and u get what u wanted. You need not care about the "constant" coordinate, as where the control is located.

Just to share out some good stuff here. Feel free to shoot me.  🙂

hi, 

i modified yours with more flexible, no need manual offset when the table is moved
