Google maps ShowInfoWindows didn't appear the windows

Dear All

I had try to using google maps extensions 2.5.32.

When i want to showInfoWindows, the windows didn’t, only show “arrow image”.

I had try debug in chrome, i found there trouble with class=”gm-style-iw gm-style-iw-c”,  when i add “height:200px” in chrome debug, the windows appear.

My Question is, is:

1. Any idea how to solve it, i think this couse by style overwritten but i don’t know to solve it.
2. i had try using this code below to solve it

Dim htmlContent As String =
“<div style=’height:200px ; width:200px !important; overflow:auto !important;’>” &
“<h3>title</h3>” &
“<p>Custom content goes here…</p>” &
“</div>”
GoogleMap1.ShowInfoWindow(e.Marker, htmlContent)

Dim js As String =
“document.querySelectorAll(‘.gm-style-iw.gm-style-iw-c’).forEach(function(el) {” &
” if (!el.style.height) {” &
” el.style.height = ‘150px’;” &
” }” &
“});”
js = js & “document.querySelectorAll(‘.gm-style-iw-chr’).forEach(function(el) {” &
” if (!el.style.height) {” &
” el.style.height = ’30px’;” &
” }” &
“});”
GoogleMap1.Eval(js)

but the code above, only work when the showinfowindow success load, i try to add listener “google.maps.event.addListener(GoogleMap1.getInfoWindow(), ‘domready’, function() “, but error GoogleMap1 not found in chrome debug.

Thanks all for your support
