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:

• Any idea how to solve it, i think this couse by style overwritten but i don't know to solve it.

• i had try using this code below to solve it

Dim htmlContent As String =
"

" &
"

title

" &
"

Custom content goes here...

" &
"

"
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

Nicky

Hello,

A few issues here:

• You said you are using 2.5.32. Wisej 2 is no longer supported. You are welcome to ask questions about Wisej 3 or 4 on this forum

• We would need a runnable test case in order to investigate this issue, using Wisej 3 or 4. Please attach one if you want us to investigate this further.

Thanks,

Julie
