[Solved] Google Map in RadGrid

[Soren Michelsen]

I have a radgrid bound to a database containing geographical data:
Location (ex. "London")
Latitude
Longitude

The grid displays the Location field, and in a NestedViewTemplate, I display a Google Map with a marker set at the latitude/longitude coordinate.

To only allow one item to be expanded at a time, I have enabled "Single Expand" according to this article:
http://www.telerik.com/help/aspnet-ajax/grdsingleexpandinhierarchicalgrid.html

What I'd like:

1. To be able to collapse the single expanded item. Right now I can't do that. Here is my current ItemCommand eventhandler:

If e.CommandName = "ExpandCollapse" Then
    For Each item As GridItem In e.Item.OwnerTableView.Items
        If item.Expanded = True Then
            item.Expanded = False
        End If
    Next
End If

2. To ajaxify the grid to prevent full-page refreshes when I expand a new item. Right now it fires an "access is denied" error if I try to ajaxify using a radAjaxManager.

A simple project that replicates my problem can be downloaded from http://www.stmtest.net/GoogleMapsGrid.zip

Note: Telerik dll's are not included in the /bin folder in .zip

Any ideas appreciated,

Hi Jeppe,

I suggest you review this code library which demonstrates how to expand/collapse hierarchical grid with ajax request on row double-click (without page refresh). Feel free to modify the code logic to be executed on single click.

Hmmm... the last four bullet-points in the addition to the original post are (for a newbie like me) very, very vague.

Any way anyone can elaborate on those or maybe even provide  a working example with a current version of RadGrid?

Thx :-)

Yes, very similar issue, but have switched to Bing Maps (Microsoft).

I will post solution here once we get there :-)
