Hi,
- Declare your variable as public in the aspx.cs
- in your .Aspx use : <%=myVar%> in any place

سلام
اگر فارسی می نویسیم به این دلیل است که از نوع عناوین جنابعالی فهمیدم که ایرانی هستید.
به هر حال برای Bind کردن DetailsView با این روشی که شما انتخاب کرده اید و از SqlDataSource استفاده می کنید، برای گرفتن نتیجه باید از DetailsView1.DataSourceId استفاده کنید درضمن هنگام تعریف DetailsView میتوانید در کد های HTML نیز این مشخصه را تعیین نمایید برای مثال:
asp:DetailsView ID="dtl1" DataSourceId="SQLDS_ALLV_TitleIE" runat="server" ..... /asp:DetailsView
در ضمن بهتر است دستور Select شما حاوی شرطی باشد که موجب برگرداندن یک رکورد شود.
اگر هم با SqlDataSource مشکل دارید می توانید از DataTable استفاده کنید.
البته با عرض معضرت باید بگویم که روشی که شما انتخاب کرده اید با مراجعات متعدد به سایت رفته رفته از سرعت آن کاسته خواهد شد یعنی خاصیت SqlDataSource چنین است که در هر بار PageLoad اجرا شود در حالی که شما فقط به یکی از SqlDataSource ها نیاز دارید ولی در هر بار هر دوی انها اجرا خواهد شد که این روش خوبی نیست.
به هر حال اگر به نتیجه نرسیدید اگر کمکی از دست من بربیاید یا در همین سایت و یا به آدرس abolfazl585@yahoo.com میل بزنید.
باتشکر

Hi all,
I use Application object in ASP.NET.
I set it’s value in one page and read it in another page but I don’t know when I can dispose this object in order to in the first page it’s not set and if an event accord it set again.
Thanks in advance

You should only use the application object for things you want to keep across user sessions. Like some sort of static data that all users would be looking at. It sounds like you should be using a session variable to pass things from one page to the next. Session is very similar to the application object except it is only for that user, other users can see that object, they can only see their own session object.
Either way if you want to remove and object from the session or application you can just set it to null or Nothing in vb.net. There is also a Remove method in the object to remove something from the application or session object.
Hope that helps.

When i can use it?(What event)
|
|
|
|
|
You can use the session and application object anywhere in the codebehind. All events have access to it.

I use it in Finalize Method of the page but in order to access again to it i don't know What i can?
|
|
|
|
|
Perhaps it is better for you to explain what you are trying to do and then I might be able to suggest something for you to try. Finalize method of the page seems like a strange place to set a variable in session or application. Most of the time I set it in th page load event.

You have to grant WRITE permission for asp.net account, I think
<< >>
|
|
|
|
|
manage your asp.net account permissions
or config your web.config file

create new folder in your hard drive. c:\temp for example.
select it and right click over the folder and chose properties.
select the security tab and then press add button to adding new user.
select aspnet user and press ok.
in the permissions section allow fullcontrol access.
then your operations(delete,modify,create,...) must be referenced to this folder.

I'm not sure...but here is just a suggestion
Open IIS MMC, check the ASP.NET version setting of your site
<< >>
|
|
|
|
|
goto windows\microsoft.net\framework directory and find .net Frameworke version that your application use it and from it's location find aspnet_regiis.exe and execute it such as "aspnet_regiis.exe /i"
