Question

Ajax ModalPopupExtender and Google Map

Asked by: vbnewbie01

hi, there; using asp.net 2.0 (vb), i have placed a ModalPopupExtender on my page containing an asp.net panel and, within this, a google map.

first off, let me say that this map displays perfectly outside of the ModalPopupExtender however, when i place it inside and click the link to reveal the ModalPopupExtender, the google map does not display entirely (see image: http://www.gigantech.com/dkelly/modal.jpg)

i have scoured the net without much success but did happen to come across one poster who had a similar issue:

http://forums.asp.net/p/1091908/1848191.aspx

unfortunately, i am not using javascript as this poster is.  my data is pulled from sql server then attached via a procedure, to the google map.  that said, i still tried to use the poster's OpenModalPopup function but without success.

i'm wondering if anyone has had a similar issue or has any solutions to resolve what appears to be a bug.

thanks in advance.

<div>
       
        <asp:linkbutton ID="lbMap" runat="server">Click to see map</asp:linkbutton>

        <div>
        <Reimers:GoogleMap ID="gmMap_lg" Width="600" Height="400" runat="server"/><br /><br />

        <asp:Button ID="cmdOk" Text="Okay" runat="server" />&nbsp;
        <asp:Button ID="cmdCancel" Text="Cancel" runat="server" /><br />

I've had the same problem, I used a workaround.... Put an Iframe on the page wich is displayed in your modal window and use it to display the google-map.

It seems to be a problem in the timing on wich all the components are loaded into the page...

 

by: vbnewbie01Posted on 2007-08-20 at 14:54:20ID: 19734056

perfect.  thanks, psodermans.  i can't tell you how long i searched for a resolution or, at the least a work-around to this.  good suggestion ... i wouldn't have thought of that.

on a side note, i've also run into other timing issues ... for example, displaying a control (in my case, another google map) within an ajax AccordionPane.  

for anyone having a similar issue, i resolved it with this workaround:

http://couldbedone.blogspot.com/2007/07/what-wrong-with-accordion-control.html

basically, add:

Accordion1.FindControl("nothing")

to the Sub Page_Init() event:

Sub Page_Init()
        Accordion1.FindControl("nothing")
End Sub

hopefully these issues will be resolved in the next ajax release.

thanks again!!
