You can use threads to fetch data for the different grids. Threads were independently and you can use ajax to show busy indicator.

Is it perhaps "jumping" to align with another control? Or is it inside of some flow control that determines where its children are positioned?
If not, you can always position it precisely with the arrow keys or by typing the position in the properties.

Hi tridip
Here in vs 2008 you can not move control directly by selecting it,,, to move controls you just click the lines of a control in left corner then move to left or right ,if you want to move top or down positions you have to click on left top corner lines then drag the position where you want.
Hope you understand the answer..

Tridip Bhattacharjee wrote: i want to generate a div dynamically
You can create a new div, or other way you can have a div design time in display:none state,Now whenever you require,just change the display property and set the top and left property and also height and width.
For that you require , the position of the multiline textbox ( which renders as textarea) and set it to the div.

thanks for reply but it would be better if u provide some code for my requirement.

The below code gives you the position of an object passed
function findPosition(obj)
{
var curleft = curtop = 0;
if (obj.offsetParent) {
do {
curleft += obj.offsetLeft;
curtop += obj.offsetTop;
} while (obj = obj.offsetParent);
}
return [curleft,curtop];
}
pass the DOM object to findPosition and get the position of the textarea.
Now set the top and left with this position.
Also set the width and height of the div as your textarea.

Relatively new to asp.net. I want to develop a page that uses an AJAX Tab Panel Control. Based on the tab, the user selects, a filter is applied to the result set shown on a grid. I'm wondering if I should just have the tabs display without showing anything in the tab itself, or develop a custom control (.ascx) which I would include on the tab, thus I'm writing code once instead of having a unique grid on every tab.
If I use the custom control and have the grid on the tab, how do I access controls on the .aspx page? Simple example. I have a label on the .aspx page which displays messages, based on what someone is doing on the grid. If the grid is in the .ascx, how do I access the label in the .aspx?

Just wonder is it a good practice to host web site and web services in the same app pool and same virtual directory ?.
The asp.net web site will call the business facade directly and the web services will host the business facade for others .net application.

It's better if assign both web services and web application, different application pool.Because if you are consuming your web services from multiple applications, then if your app pool gets down due to web application problem, your webservices will also be down. And rest other other application will not be able to use it.
But if webservices is just consumed by one application, then you can deploy in same application pool

Hi All,
I am using asp.net MVC 2 and am having an issue running two getJSON commands at the same time.
However I try to re-arange the code the second one waits for the first one to finish before runnning. Consider this code as an example.
var InProgress = false;
function Start(){
InProgress = true;
DoSomething();
UpdateProgress();
}
function DoSomething(){
$.getJSON("url", {}, function(data){
InProgress = false;
$("#text").text("Complete");
});
}
function UpdateProgress(){
if(InProgress){
$.getJSON("url2", {}, function(data){
$("#text").text(data.Percent);
setInterval(UpdateProgress(), 500);
}
}
}
Basically, I am trying to get a progress report for the main process.
What is happening is...
Start() called
UpdateProgress() called
text updated
DoSomething() called
UpdateProgress() called (But only after DoSomething getJSON has finished)
The whole process runs for about 5 - 10 seconds so UpdateProgress should be called many more times.
Can anyone help with why this would happen? I cannot find anything on the web to help me out
Thanks
EDIT
--------
I have found what the problem is. I was using Session (assigning the progress value to) in the Actions that the getJSON commands called. And for some reason this was forcing the second getJSON to wait. Removed session references, problem fixed.
However my problem now is, what do I use instead of Session. I basically need to persist a variable value across multiple action calls. I understand that essentially for two action to run together then they must be on different threads somewhere along the line. So I guess that is the issue.
Any idea's cleaver people?
Life goes very fast. Tomorrow, today is already yesterday.

Tridip Bhattacharjee wrote: another thing i notice that when i comment all the line in function ShowDiv() then postback is not happening.
This is happening because there is an error in your code. Once there is an error, return false; is not getting executed, that's why postback occurs.
The error is in lines
modalWindow.style.left = (modalWindow.style.height - getDocHeight())/2; modalWindow.style.top = (modalWindow.style.width - getDocWidth())/2;
here you are trying to like 180px-100px, so this is throwing an error. Get the height, remove px from the height then try, it will work

Because of Masterpage's heaving occupying space, it is difficult to design content pages.
Is it possible to switch content page w/t or without MasterPage in DesignView.
|
|
|
|
|
I don't think, there is any way.
But another way you can do, create a page without master page, do your designing and and at last, change the page to content page.
|
|
|
|
|
No , its not possible, mybe what you can do , create a Master page and dont do anything to it, just add content pages and start working and you will have a lot of space. When you are done , then link it with the final master page
