that it’s only within the OnSelectItem event that SelCount appears 0.
Using a 1ms Timer to display the SelCount is working, but rather crude in my

<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'>In D7, I’m
using a Virtual ListView (OwnerData=true) for the first time in a project, and
there appears to be a bug in the VCL. I’m hoping I can make a fix in the
VCL code if possible.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'>I’ve searched
the internet and found a person asking the same question on a forum but no one
answered him.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'>The ListView is
MultiSelect. When using Shift Click to select multiple items, the
SelCount property returns 0. When using Ctrl Click to select multiple
items individually then SelCount is correct.<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'>I would rather
not traverse all the items to check the selected state as this could be in the
hundreds of thousands. Does anyone know of a fix?<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></p>
<p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'>Many thanks.<o:p></o:p></span></p>
