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.

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.

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

hi guys. i have strange bug or problem with this two controls. i will simplify my code as much as i can.
i have this markup:
<asp:FormView ID="fv" runat="server" DataSourceID="sds" DataKeyNames="id">
</asp:FormView>
<asp:DetailsView ID="dv" runat="server" DataSourceID="sds" DataKeyNames="id">
</asp:DetailsView>
<asp:SqlDataSource ID="sds" runat="server" ConnectionString="<%$ ConnectionStrings:TestConnectionString %>"
ProviderName="System.Data.OleDb" SelectCommand="SELECT * FROM [tablica]" >
</asp:SqlDataSource>
and lets say i need on first PageLoad get SelectedValue from eather of these:
protected void Page_Load(object sender, EventArgs e)
{
object fvValue = fv.SelectedValue;
object dvValue = dv.SelectedValue;
}
so here is strange situation (looks like evil bug!). fvValue and dvValue have null value, but debuging code using Visual Studio with brakepoints; when i collapse fv or dv and navigate to SelectedValue property it changes from null to "something"?
anyone encounter this situation?

I have a page which does an upload functionality. Once it is uploaded successfully, I should be able to go to the third step of a Wizard control in another page. Is it possible to do so? Could anybody please help me on this? Any links or tutorials is fine.
Thanks in advance

If you are using the ASP.NET Wizard control then you should be able to set the ActiveStepIndex to the appropriate page.

Thank you for the reply.
I am using ASP.Net Wizard Control only. But I need to come frome another page to the Wizard page. For eg. I have two pages, a.apx and b.aspx. Assume that Wizard controlis in b.aspx and Upload functionality in a.aspx. Once the upload becomes successful in a.aspx,I should be able to navigate to the 2nd or 3rd step of Wizard Control in b.aspx. Is this possible in Wizard Control?
Is it possible to write something like FindControl in a.aspx by referring the b.aspx page and setting the activestepindex in a.aspx itself so that it directly come to the 2nd or 3rd step of Wizard control in b.aspx?
Thanks

I think you need to stop and think a bit, and learn/understand the asp.net model.
You can't find a control on page b from page because it doesn't exist until the page is served.
What you can do is pass the data to set the wizard from page a to page b via query string or session variable. Then in your page load event set the wizard property appropriately. This is basic ASP.NET development.

What are industry standards on customizing a product to fit your needs, such as aspdotnetstorefront? Changes may include source code change, database structure changes, etc. When there is any upgrade to the product, it should be smooth process w/o loosing the customizations.

You can't add a control to the textbox, what is most likely happening is a div containing the progress indicator is floated over the textbox. You can use javaScript to asertain the positions and widths to position it correctly.
