Web Forms :: Google Map API And Javascript GetElementById?

Mar 8, 2010

I'm trying to get the Google map API to work with ASP.NET. I got it working on an HTML page but it does not work on a ASP.NET master page/content page. The problem seems to be getElementById not finding a div assigned to an ID.

Forms Data Controls :: Find Control Inside A View Of Multiview Using Javascript (document.getElementById)

Nov 19, 2010

i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function.

On the HTML code is rendered only the first view or the view that is activated on page load.

Is there any way to find a control inside the view using javascript? or I am doing something wrong?

Web Forms :: Trying To Pass A String Variable As A Parameter To The Document.getElementByID Function

Jan 17, 2011

I have a label "lbl1" that I am trying to locate in a content page from the Master page. I want to do it dynamically so I am trying to pass the name of the control (which in this case is lbl1) through as a parameter. I don't get an error, it just doesn't work. If I do an alert to see what the string "temp" looks like, it is correct, but iit seems as if Javascript ignores it. I believe it has something to do with the '<%= not being interpreted correctly by the browser&nbsp; I'm sure it is a simple solution, but I can't figure it out!

I have a page with some datasources in it. I am doing reenginering of the page itself and would like to split some parts of the page in several user controls. In my code I have an ObjectDataSource object with the following params

<asp:ObjectDataSource ID="ObjectDataSource1" runat="server"
TypeName="DataSetTableAdapters.PhotosTableAdapter"
SelectMethod="GetPhotosForAlbum">
<SelectParameters>
<asp:ControlParameter Name="albumID" ControlID="txtAlbumID" Type="Int32"/>
</SelectParameters>
</asp:ObjectDataSource>

This piece of code automatically bind the hidden field "txtAlbumId" to the datasource. In my revision this datasource should be moved to a user control. What is the best way to handle a scenario like this?

The value of the parameter will be seletectedValue of the first dropdownlist ddlCategoryFooter&nbsp;or&nbsp;ddlCategoryEdit).I know it could be done in code behind, but i prefer to bind my datasource in asp page.

Getting Javascript Libraries From Google / Microsoft CDNs Through SSL?

Oct 7, 2010

I'm getting a couple of libraries from Google / Microsoft CDNs.

ONLY one page on the system uses SSL but since I'm referencing libraries on the master page I'm getting the javascript libraries using the SSL so the single page that actually requires it doesn't throw security errors because accessing unsafe resources.

I've read that the browser cache doesn't work for most of the browsers if the resource is loaded using SSL, my test using fiddler indicates the opposite (Firefox and IE).

What's the truth? I'm using the CDN for improving performance so if getting the library using SSL is against my purpose, I would revert this "improvement".

I could build send the code for referencing the library on the code behind ans use SSL or not according the case, but I would like to avoid this.

Javascript - Loading Webpages That Contain Google Adsense?

Nov 11, 2010

I have been experiencing some issues loading some web pages from my development machine. They were painfully slow. I disregarded this until I tried running my own site and found that the culprit was the show.ad.js file provided by google adsense.

Using firebug I see that the page hangs on the loading of this file and then aborts after about 5-10seconds. If I am calling multiple database records to a page it will load one, hang, abort and then load another.

Trouble shooting I have done and things I can rule out are:

My router or any other external peripheral. If I go to any other PC in the house the page loads fine and very quickly. I have tried cabled and wireless. The problem appears to be something unique with my machine.
It is not just my website, it is all websites with google adsense. I have turned off my firewall and shutdown anti virus. No change. It is from all browsers on this PC. I have tried chrome, safari, firefox and ie. No change. I do not have any ad blocker software installed that I know about.

I know there could be a million reasons why I could be having this problem but I thought someone out there may have had a similar experience. Failing that, is there any way I can trace the problem as I have no idea where to start.

My question - the example code shown below there does not move the gauges like that (or at least when I tried it in my own project.)

how to get it moving dynamically like that?

(Also, will these gauges slow down my site connecting to Google? On the other hand, will it bring up my rankings?)

Forms Data Controls :: GridView And Html Select - Find The GV Object (getElementByID("GridView1") Returns Null)?

Jul 10, 2010

I have a webpage with a select object and a GridView object. For testing my problem i've created asp button and html button.On pageLoad the GV is empty and select is being filled with names. (GV is not appearing)After choosing a name from the select options, the user should click a button and then the GV need to be filled with relevant info.I am having 2 "related" problems:

1. When clicking on the asp button and getting into the click function on the aspx.cs file, i can't find the select object and retrieve the selected option. How can i get this?

2. When clicking on the html button and getting into the button_click function on the aspx file (javascript), i can't find the GV object (getElementByID("GridView1") returns null). I guess that it's because the GV is not loaded initialy since it's empty.I've tried also using callback methods, but the although it seems like i am reaching the GV and performing DataBind(), the GV table won't show on the page.
