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.

Javascript - Developing Application, Use Google Maps Or Bing Maps?

Feb 17, 2011

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?

With Google Maps, Can Use Google's Own Popup Windows

Jan 11, 2011

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.

Web Forms :: Button Onclick Event Not Firing After Postback?

Sep 24, 2009

I have an asp.net button to which I am adding onclick as an attribute from code behind like this

CType(fvBasicDetails.Row.Cells(0).FindControl("btnUpdate"), Button).Attributes.Add("onclick",
"javascript:alert(""hey"");")

This javascript fires when clicked on the button after page loads for the first time BUT never works after the post back!

Web Forms :: Attributes.Add() Onclick Event Disappearing After Postback?

Mar 29, 2010

- 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.

Web Forms :: Button Onclick Event Only Triggers Postback On The First Click?

Nov 11, 2010

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.

Getting User Input From Google Maps?

May 22, 2010

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).

Newbie, Trying To Add Google Maps To Site?

Nov 13, 2009

I am trying to figure out how to set up Google Maps for my site. I just signed up for Google maps and received a Google Maps API Key. I am in the very beginning stages of this. I've been using ASP.NET (ver 3.5) for about 6 months and SQL Server (2008) for the same amount of time. I've read several books on both ASP.NET and SQL Server, but really I'm pretty new to this stuff. Before this, I have been programming in VBA for about 6 years (doesn't help much in .NET-world).

Here is a link to my site:
[URL]

I am planning to add Google Maps so a user can click on an address for a pub (in New York City) and see the location in a map. Or, perhaps click several locations and see all on a map. How hard, or how easy, is it to do these things? How do I get started? What do I need to do?

C# - Put A .net Control In A Google Maps InfoWindow?

Dec 20, 2010

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).

<html>
<head>
<title>
title here
</title>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=true"></script>

Getting JS Data Back In VB - Google Maps API?

Jan 2, 2009

I'm using the Google API, which is accessed via Javascript.

For a given zip code, I'm getting the lat/long values.

I wanted to use this in a web service, but since I have to access it via JS, it won't work directly in the web service.

What I did was created a .aspx file that accepts a location parameter, which gets fed in to the onload Javascript event.

When I run this, getlatlong.aspx?location=90033, manually, I get an output.

When I call the page from my web service via WebRequest, there is no output. The idea was to parse the page output for lat/long.

I realize that JS is executed on the browser, so that makes sense. However, a while back a fellow programmer wrote a website spider where he was able to add the browser type to it. Using this format, I don't think this would still execute the JS, but I'd like to find a way to get this working.

So how do I create a VB Javascript wrapper, so I can get these values back from JS in some code-behind?

In short, what I need is to be able to call JS functions from the code-behind, and get the results in the code-behind.

I've already seen the C# libraries, and http://an-it-solution.blogspot.com/2008/12/use-google-maps-in-aspnet-c.html# seems decent, but I don't need the full functionality of the C# library, and don't need to rewrite the whole thing.

On the other hand, can I import the DLL and just use that in my code for getting lat/long?

C# - Stop Setting Onclick Event For LinkButton If No OnClick Event Was Explicitly Defined?

Feb 25, 2010

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)

Web Forms :: Implementing Google Maps In Website?

Sep 25, 2009

I've been asked to implement Google Map into an existing ASP.NET 3.5 website.In addition to implementing the map they also wants locations to be stored in their existing database - so the website can display locations stored in the database. For example having restaturants in a town on the map

Now I wonder how to implement this. Is there a ASP.NET control I should use or should I do what Google says in it's tutorials?

Make Google Maps API Get Restaurants In Specified Area

Jul 7, 2010

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.
