I’m sure there must be a reason: Why is a Grid row’s height greater when a subrow is present. See screenshots below. The difference is obvious… and, I might add, undesirable!
This issue also seems to be affecting TreeGrids as well. See screenshot below.
(Custom images shown are all 18px high, just like the samples included witht the Grid control)
Because of the higher row height, Tree Grid Lines cannot be enabled, since the vertical descenders don’t link up. I tried this with the standard/default leaf.gif images and the same higher row height was manifest.
The issue does not appear related to my own additonal css file, since I can remove it entirely and the higher row height is still present.
I have discovered why the row heights are different when grid subrows are used, or when using treegrid. This symptom will occur if enableMultiline is set true. I believe this to be a design flaw, or a bug, since I understand enableMutliline to be an inline editor option and, as it turns out in this case, that option is not being employed. In any case, my more immediate issue is resolved.
