Yes. App_Data is storage for files like Mdf, XML etc. The real advantage is that any file you place in App_Data won't be downloadable.
Those file can be accessable by developer/Coder but not from outside, because these are not downloadable. This is the reason I guess Image not showing, as they get downloaded.
Please share your input.

Yeah. You are right. I just tried with a simple sample. The image in the App_Data is inaccessible. Good to know.

Hi,
i developed the application in .Net Framework 1.1, the same application is working other Operating System Machines except Windows 7. if i open the application in Windows 7 Machine and click any buttons the Validation controls not working. What should i do for this? should i do any setting changes for this?
|
|
|
|
|
Could you give a few more details? (i.e. code snippet) Were you using regular expression validator controls or similar? What browsers have you tried?
|
|
|
|
|
I used the required field validator control, for checking the text box is null or not. but the same application is working in other operating system server. In the Windows 7 System , IIS is 7 and IE 8.0
. In other OS Machine when we click on the buttons it is checking the textboxes and showing the Error Messages.i copied the same application in other machines.

Hi,
this is no direct answer to your question - so sorry in advance - but maybe you can solve your issue
the other way arround. Target your popup extender to a simple label like:
<asp:label id="NullControl" runat="server">
<ajax:modalpopupextender id="someExtender" runat="server" targetcontrolid="NullControl"
="" popupcontrolid="DetailsPopupPanel" cancelcontrolid="CloseButton" dropshadow="false">
And then, when your itemcommand fires, open the popup from codebehind using [extenderName].Show();.
Im doing that in a gridview and it works perfectly.
Good Luck
|
|
|
|
|
Don't set the target to the link button. Set it to some other button outside the repeater that isn't visible. Then in the item command call .show on the popup control. If you don't want a full postback you need to wrap it all in an updatePanel.

If you are using a button to trigger the postback you could examine the data in each listbox within that event and store the data in some way (Session, ViewState, etc) and repopulate the boxes during the OnLoad event taking into account that this is a PostBack so you might have a method like:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
if (IsPostBack)
{
}
else
{
}
}
That should get you started.

Hey Abdul,
Changes done in the client-side using JavaScript will not save it ViewState. To ASP.NET, it doesn't know that you have changed something. To fix this, use a hiddenfield. When you hit the button, get the list of item into the hiddenfield with delimiters. Once the page is back, fill the list with the items with the hiddenfield value.
Only HiddenField can maintain states all the times.

|
|
|
|
Thanks, HiddenField do save the status, Its really appreciated.

hello all,
I want to fetch the static text written at html design page and then fetched data be entered into some variable at code-behind.
could anyone know the code to do so?
|
|

You might face problem of having some html into string variable. Please use the class "HttpUtility" and it method/property as required.
Thanks,

If content is inside a td/div/span/p then you can give the container control an Id and set its runat="server". At the server side you can access the control text using the InnerText or InnerHTML property.

I think you have problem for getting server side error when enter html code in textbox.
For the security reason asp.net does not allow this.
But you can enable it by making
<%@ Page validateRequest="false" %>

Do you have screen to upload the files? If yes, check whether it is uploading to the right location or probably uploading?

You can give a try just checking whether you have anything 'hard coded' inside the application code.
Even deleting from source downloads the same file prompts me thinking same.

Is it possible to use ASP.NET Control in MVC Patterns

Why not! You can use them... MVC is a pattern..There is a framework too that can be used to build ASP.NET application using it.
