AJAX :: Implementation Of Seadragon And Preloading Images
Oct 4, 2010
I've been implementing Seadragon (as part of the ACT), but have recently found some users complaining of slow speeds whilst using it - I thought this odd because the whole idea of Seadragon and DeepZoom is streaming images as they're required rather than loading one huge image in one request.
I've done a bit of testing (using Firebug) on both our web pages and the ASP.net ACT Sample website Seadragon control, and have found that when the control is opened on screen, the browser decides to load all the tile images at once (even the tiles which aren't at the default zoom level).
Has anyone else experienced this and does anyone know why it does it/if there's a fix? The fact it happens on the ACT sample site has left me tearing my hair out because I know that it's not just my implementation of the control that's causing problems.
I need to display multiple images in seadragon. I have developed these in deep zoom compmser and checked in preview, it works fine.but when i put this in seadrgon's sourceurl,i am facing the following error. icrosoft JScript runtime error: Object doesn't support this property or method.
Has anyone ever tried to put a seadragon control in an accordion extender? I just tried and I can't get it to work. The seadragon control dosn't render the image when you open a pane in the accordion. Something like this...
I used the DeepZoomTools.DLL to convert a JPG file to XML using the following code:
In my appliction I have 4 tabs. Ex- HOME,ABOUT US,LAYOUT,CONTACT US. these tabs are in tabcontainer. Using Seadragon I have created the image(LAYOUT).Image is displaying only when I set the Activetabindex to LAYOUT. Otherwise it is not displaying the image.
use a textbox and the AutoCompleteExtender to search for the customer. For example, on the PurchaseOrder form, I have a textbox with a Customer field, and when I type in the name of the customer, the AutoCompleteExtender shows the possible matches.Now, it takes a few seconds to show the list of values, even with setting the correct values on the extender, and if the user types in the name of the company, e.g. Contoso, and leaves the textbox, there might be 2 Contoso's in the database. The AutoCompleteExtender does not continue when the user leaves the textbox, thus the CustomerId is not determined yet.
I'm trying to implement an auction website and I search in web the Ajax Push is the best way where I can use! So, I'm finding some samples in web to learn how to implement Ajax Push (comet) in client and server. By the way, I find some samples in ASP.Net Webforms, but no in MVC version. I'd like to find a demo, sample, anything ... that use MVC
i have a template page which open from several page and load the data from several tables in data base.want to know what is the best way to implement this tepmlate page?i want some nice control to implement this page.i wrote its code but want use some graphical controls like rad window to implement it. i use rad window but it doesnt enough to me.
I have teh seadragon working, but when I try to active it with a hovermenu or popupcontrol, I don't get an error, I just get everything except for the actual image. It has the background, the controls of enlarge, shrink etc, but no image.
This is Ravi and like to learn AJAX concepts,and wrote small application ,but getting response along with html page .

I like this idea when I don't have to use slow expression compilation to be strongly typed. But the current implementation is too aggresive for me - I hate virtualization my action methods.My question is: Are you planning some (branch) implementation that will not require action method virtualization? I think that most of code could be shared in both branches...
We have application build in asp.net in which on button we need to go to OBIEE dashboard. Similarly need to come back from OBIEE to ASP.NET application.
Currently I am using redirecting from ASP.net page to OBIEE with username and password in the URL. But as per my requirement i need to implement SSO or username and password should not be passed in URL query string.
When using a databound control the Bind() method does some magic to first extract the current value from the datasource and then pass an update back to the datasouce when an update is performed.
Now I have created a custom datasource and am supplying my own custom data which all works fine. For read only the following code works a treat. As you can see I am accessing both a named index into the collection and a property.
Now when using Bind() I cannot find a way to accomplish this. Bind() would appear to look for either an object property or a database row column (not sure how it does this) and I cannot find a way to change this.
It shouldn't be that difficult because the hard part is obtaining the data, which my code below can already do. The changes are passed back as a dictionary which should be simple. But I need a way to write my own bind method and I haven't managed to find out how.
I'm fairly new to dependency injection but it seems like a proper DI implementation will be fairly complex.
For example, DI requires a centralized class that manages the configuration and resolves the dependencies at runtime.
DI is also based on the concept of using interfaces. For example, a SpecialLogger should use an ILogger interface.
The centralized DI manager class will need to register types - for example, associate ILogger to SpecialLogger.
SpecialLogger will also need to implement the ILogger interface so SpecialLogger can be used through the DI ILogger interface.
Therefore, it seems like a sln using DI will need multiple projects to support DI. Here is an example for logging:
* MyCompany.MyDivision.Framework.DI.Management - this would have the DI manager where dependency types are registered and resolved at runtime * MyCompany.MyDivision.Framework.Logging - this would have the implementation of a logging class. The main logging class would need to implement ILogger. * MyCompany.MyDivision.Framework.DI.Interfaces - this would have the ILogger interface.
Interfaces would need to be stored in a separate class library from the DI manager because both the DI manager and SpecialLogger use the ILogger interface. Since the DI manager associates SpecialLogger to ILogger a circular reference would be encountered without a separate class library to store the ILogger interface.
I want to use Event Aggregator to allow communication between presenters on the page. I am using currently this implementation http://kentb.blogspot.com/2008/03/event-hub.html. But in asp.net I am not sure about side effects which can occur.
