webos background image updating problem -


There is a priority screen in my application that has a feature to change the background color or theme, I am using PNG images as well. When I go to the main screen, I am using some other image based on the selected image in the preferences. To do this, I am changing the background image with the CSS in the inactive () method of the priority screen, in the emulator, it works fine. When I install the app on the device and check the same case, it shows the blank, then it changed the main screen image.

How can I avoid the moment of the empty background in the transition from the main location on the screen?

It seems that the second is going to load the image. You can sprat images together so that they are always stored in memory, or you can create a new image in JS and run visual transitions when the image is loaded. 

  var img = new Image (); Img.onload = function () {/ * Run the visual transition} Img.src = "path / in / by / background";

'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
