Google Maps Onclick Event To Cause Partial Postback Of Page C#?
Oct 21, 2010
I have used jQuery to invoke an AJAX webmethod in c#. This webmethod runs a query and stores the resulting information in a session variable. I have a gridview that has an objectdatasource that uses the session variable with the selectmethod to then populate the gridview with data from a query. I need the final piece to get the gridview to databind() again with the new value.
So click map, update gridview. However, maybe I'm going about this all wrong. In essence, take javascript variable, push to ASP.NET in C# and refresh gridview on page with new data from query.

I need to use a map in an application that I develop. In my application I want to use pins that will show infoboxes on the map. Use the zoom in, zoom out functionality and the ability to show several maps on the same page. I won't need to use the search locations or routing directions.Which type of maps should I use? Google or Bing? As I understand, they both have good user interface, but which one is easier to develop with? If I'll use Bing then will it be more Microsoft like, I mean, it will let me use visual studio convenient programming? More or less javascript so it will be a hassle do debug it?

I have a database table with Lat, Long, City and Url colums
On aspx, i am using google v3 maps with markerCluster enabled to.
The problem i am having is the map loads fine and shows the clusters. when i click the cluster it zooms to the markers but then If I click a marker I want it to redirect to another URL - that corresponds to that marker in the SQL database - Url Columns....
All my code is below:
<link href="Style/PlayMeStyle.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src = "https://maps.googleapis.com/maps/api/js?key=xxxxxxxxxxxxgEk&sensor=false">
</script>
<script type="text/javascript" src="http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/src/markerclusterer_compiled.js"></script>
<script type="text/javascript">
function initialize() {
[Code] .....

- I've created a Survey with multiple sections in it
- The answer types are variable and, thus, the controls are created dynamically
- I have a Repeater where each RepeaterItem corresponds to a Category. (I have 5 categories in my current test, so I have 5 DataItems in the Repeater) Each RepeaterItem contains another Repeater which will hold the Question / Answer values
- After I data bind the Category Repeater, I loop through each RepeaterItem, find the Repeater contained in each RepeaterItem, and DataBind() this second Repeater to a list of Questions
- After DataBinding the Repeater containing the Questions, I sent that Repeater object to another routine, which is where the Answer controls are dynamically created and added to a Panel inside each of this Repeater's RepeaterItems.
I am able to navigate back-and-forth among Categories, save / delete answers, and fill in answers for Surveys that were left incomplete when a user logs back in.
One of the the potential control types for an answer is a ComboBoxList.
Each Question has an option for answers that require a ComboBoxList called "MaxAnswers." When this value > 0, I inject a little javascript that prevents the user from selecting more boxes than the "MaxAnswers" value. This is done during the last step described above like so:
[Code]....
This appears to always be added regardless of how many questions I answer or don't answer or how many times or directions I navigate around inside the survey. (I can push "Back" and "Previous" buttons as well as jump directly to any individual category by clicking a LinkButton)
Another option for Questions requiring a CheckBoxList is to specify if the selection of a specific ListItem within the CheckBoxList should display a TextBox. (e.g. a selection of "Other" will display a TextBox for the user to write-in an answer) I want to prevent a post-back just to show/hide a TextBox, so I inject an onclick event attached to the specific ListItem to accomplish this. The following code appears as the very next routine following the code pasted above:
[Code]....
This also works the first time the page is loaded but not after any PostBacks...
The lblMessage.Text lines are written to the page after ever PostBack, the MaxAnswers routine correctly adds the onclick event to the necessary CheckBoxList controls, but the "fncShowFTB" event is not added. Viewing the HTML with Firebug does show the onclick the first time the page is loaded, but it's missing after every subsequent postback.
Can anyone see what I am doing wrong that causes me to lose this event?
The Firebug HTML on initial page load looks like:
<input type="checkbox" onclick="fncShowFTB(this,'FTB50');" name="dnn$ctr556$View$rptCategoryPanels$ctl02$rptQuestions$ctl11$ctl00$6" id="dnn_ctr556_View_rptCategoryPanels_ctl02_rptQuestions_ctl11_ctl00_6">
After PostBacks, it looks exactly the same except that the onlick event is missing.

I have created a user control which has a form and 2 buttons; Save and Submit. Both buttons are created at design time. Users can enter details in the form (e.g. title and description of an item) and click Save which does some server-side processing to create an 'Item' then clears the form.
The buttons:
[Code]....
[Code]....
And a placeholder to add dynamically created controls:
[Code]....
I am saving the Items in ViewState and dynamically creating a LinkButton control for each Item which allows the user to edit the item:
[Code]....
[Code]....
Now, when I test this in Visual Studio 2010, it works fine;
1. Enter Item title and description in form
2. Click Save
3. Save button triggers postback and onClick event code is run
4. ViewState list is displayed below the form
When I create a local IIS web site for testing, the postback on the Save button only works the first time I click it. Postback is false on the second click and the page reloads without running the onClick event code.

I've implemented a google map with points and stuff that uses an address that the user inputs. When you click a point, the popup bubble appears with the name and address in.Often this name and address is a prominent location, as it's used for meetings and things, such as a university. If you google the address yourself on maps.google.co.uk then you get google's own popup bubble, which often has a photo, information, opening hours, links to directions, reviews, etc. etc.I am wondering if there's a way to use that popup dialog instead of my own, where it is available. I can't see anything in the API to do this.I'm using V2 as we support IE6 in a lot of our users, but I've been told recently I can upgrade to V3 should I need functionality from it.

I am using GMap2.

How do I setup a default setting so that if I do not set an OnClick (i.e the asp.net OnClick attribute) explicitly for an asp:LinkButton tag, it will not render an onclick(html attribute for javascript) attribute client side? By default, asp.net adds an onclick='doPostBack....' for the LinkButton.
Case for use:
There is a LinkButton tag on the page. For this page, if the user has one friend, I only want to run client side code if the button is clicked and would not for any reason want to make a post back. If the user has more than one friend I would want a click to trigger a postback.
Using any asp.net Ajaxtoolkit
Dynamically switching the control type (i.e. if friends == 1 use a asp:Hyperlink)
-I want to avoid this because it is not scalable. There might be many cases where I want an asp:Link tag to do a postback or to not do a postback depending on the user context or user attributes Using OnClientClick (I am using jQuery would like to avoid this)

I have a few Link Buttons on my AJAX enabled page, all basically the same:
[Code]....
Here's the OnClick method they're attached to:
[Code]....
I ensure these LinkButtons trigger Async in my Page_Load method:
[Code]....
Then on the page there are three UpdatePanels (as called in the btnCampus_Click method). All are similar to this (only the ContentTemplate changes):
[Code]....
why the UpdatePanel's aren't triggered when clicked. I've been using UpdatePanels for a long time, but I can't seem to figure this one out.

If you map a google maps application and want to store every location the user clicks on, how can you store that data in vb.net/asp.net in a collection, with the intention of putting it in a database later.
I'm pretty sure I know how to store it in javascript, perhaps with an array, but I'm unsure of how to transfer that into the application (Without sticking it in visible text that the user sees or adding it to a form).

I used it as my POC and created a .net project from the concept. I now have markers and infoWindows being populated from the database which is pretty cool.
My problem is I want to add InfoWindows in a slick way (not only to the map, but also save to the db). Instead of having .net controls outside of the map window I want to be able to add info to the map directly. If the user clicks in the map I would like to be able to add a marker and InfoWindow with asp controls in the window (textbox and button).

I am using an updatepanel and a grid is placed within the same.Now,I have a checkbox corresponding to each row of the grid.If I check it,say corresponding to one row and click a button(placed outside the panel), a popup will be opened which is a separate aspx page having its own functionality.
The requirement is like I need only the panel to refresh not the whole page.

So far I use [URL] to get the longitude and lattitude of some address.
function load()
{
if (GBrowserIsCompatible())
{
map = new GMap2(document.getElementById('"mapHolderID');
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
map.setCenter(new GLatLng(lattitude,longitude), 15);
var point=new GLatLng(lattitudelongitude);
map.addOverlay(new GMarker(point);
}
}
So if user enters Downtown it would take the user to downtown. Now what I want is that if user searches for downtown resturants search result should point to downtown as well as list all the resturants in downtown.
