Web Forms :: Deleting A Folder Clears Static String?
Jul 14, 2010
i have an a web app where i have a .cs file and .aspx file ..I have a function called display which calls the .cs file and use the static connecting sting to display data.I have a log folder which is just used by update function.No connecting with display.
The app runs completely fine when nothing is being done.But when i delete the log foler manually and press refresh button (which calls the display method) then the static string value is set to null.It seems very wierd.I kept a break point at the .cs file declared static varaible.Its declared in class so its value is for the whole class.
public class mon
{
static string constr;
[code]...
It works completely fine (i mean not clearing the constr) until i delete a folder in the MONWeb1 directory.So what happens is that i delete a folder and when i press refresh button which instiante the class vairable.
It comes here.
public class mon
{
static string constr;
& makes it null .. (i had a watch on that variable).This is really very odd.
new to asp.net I'm trying to dynamically delete a folder so far I have this code
[Code]....
This works well when there are no files or folders in the directory. But if the directory is not empty then I get an error. How can I delete all the files and folders within that directory
I develop a simple file manager inside an ASP.NET Web site (not web application). I notice that every time I rename or delete a folder, the site gets recompiled - i.e. the very next web request after delete or rename operation takes considerably much time to execute.
It's only true for folders, not for files.Why does this occur?
P.S. I use WebDev server (Cassini), haven't tested in on IIS yet.
UPDATE: The same disaster happens with ASP.NET MVC Web Applications :(
I have put a css file in App_Data folder and referrenced it properly in the page to be used. But when I browse the page then it does get loaded and page is shown without styling. Well I know why it is happening because Asp.Net run time blocks access to App_Data folder at run time. But I wanna ask that how we can make it working that is I put the css file in App_Data folder and it still works.
I write a simple web site in asp.net. In one page i want to delete a folder of web root. When i delete it folder, the all session in project is changed to null. I write a post in this forum. Here is the adress of it post: ([URL]) Some pepole answer me to change the session state mode to StateServer. In default the session state mode is Inproc, and i changed the session state mode to stateServer.but when i changed the session to stateserver this error is appear in application eventlog after two day and my web site dont working in iis. This error is like this:

When i reset ASP.NET State service, the problem is fixed, but after one or two days, this problem apears again. What's the problem and how can i fix it? And how can i delete a folder in asp.net without the session is lost?
I have a web page, loads multiple web user controls. One Control loads Yes/No radio button and a link. Each link has a javascript to identify the radio button group and if click on link button, JS clears up the selection from radio button. It works fine in VS 2008 where I copied the page over to VS2010. In 2010, it behaves different.Here is the code.
I'm using a ListView and in both the ItemTemplate and EditItemTemplate I have, amongst other controls, an AsyncFileUpload inside a ModalPopupExtender and a RadioButtonList further down the page. The file upload process works great, but after uploading an image file and inserting it in the page, if you happen to refresh the page at that point, both the buttons of the RadioButtonList clear and one of my validation check for the RBL kicks in and an error message is, of course, displayed.
I have an UpdatePanel around the RadioButtonList, which is confusing because I thought that the purpose of AJAX was to shield the affected control from a refresh that occurs on the rest of the page.
One thing I tried unsuccessfully was to fill the RBL control again. I tried it after many different events (PageLoad, PageLoadCompleted, Databound, etc.), but none of those worked.
Actually, the RBL and DDL controls have been a real pain to deal with in .Net 3.5. Are they any better in 4.0?
I have a repeater which binds a set of data. Within this repeater is a column with various controls for updating, deleting, etc. These are image buttons which fire an onclick event such as "DeleteRecord". All this does is fire a stored procedure, passing in the ID of the record to delete from the CommandArgument of the object.
This works wonderfully... except for one rather huge problem. Once you delete a record, if you refresh the page, the record where the first deleted record used to be gets deleted. For instance... if I have 4 records
1 Record1 2 Record2 3 Record3 4 Record4
and I delete record 2... The page reloads with (which is fine):
1 Record1 3 Record3 4 Record4
...if I then hit refresh...
1 Record1 4 Record4
I assume this is because the erroneously deleted object (record3) is now in the same hierarchical place as the old object used to be and .net therefore doesn't know the difference, the page refreshes and fires the onlick event, grabbing out the command argument of the new object and deletes based on the ID as obtained from the commandargument of the new object. This is obviously a huge problem, if a client did this it would destroy data erroneously and I'm at a loss here. Is there any way to stop this from happening? I'm not sure if there is a better way to go about doing things or not. If there isn't, I need some sort of way to tell the page not to execute the event or to cross reference the ID of the object that is intended for deletion against the object itself...
Code below for convenience...
EDIT Wrapped a LinkButton around it because I have some jquery code in here as well which stops the page execution to wait for user confirmation. Pressing "ok" continues page execution.
<asp:LinkButton ID="oDeleteLink" CssClass="oDeleteIcon" CommandName="Delete" CommandArgument='<%# Eval("iAccountID") %>' runat="server"> <asp:ImageButton ImageUrl="/files/system/icons/trash-steel-16.png" ToolTip="Delete This Account" AlternateText="Delete" ID="oDeleteIcon" runat="server" /> </asp:LinkButton> protected void oAccounts_ItemCommand(Object Sender, RepeaterCommandEventArgs e) { if (e.CommandName == "Delete") { int ID = e.CommandArgument.ToString().Numeric(); db.SPs.SpDeleteAccount(ID).Execute(); UI.Confirm(uiBroadcast, "Account has been deleted", "300px"); BindAccounts(); } }
I need to keep a global variable throughout the whole time the user is at my site, but do I use Application or a static class? The string variable should store a region name and my site makes a few changes depending on which region that has been set.
I read that Application was mainly for classic ASP, but I also read that a static class cannot be instantiated at runtime (e.g. when the user has logged in).
So, have I got something wrong here and which solution do I use?
I have a details view on my page that has a template field in it. In the template field is a button that when clicked, sets the visible property of another field to true. When this happens the whole detailsview resets and anything that was entered into other fiields is cleared. Is there any way to prevent the other fields from being cleared when the hidden field is set to be shown.
I'm using a Gridview with Paging enabled. Also i'm using the Datakeys in Gridview. I can able to get the DataKeys values on first page. But when i click on the second page, i'm not able to get the DataKeys values. How to get the DataKeys values on Paging.
I have a Repeater and an update button inside the repeater
[Code]....
When I run this databound control to wire a javascript function it clears the viewstate and I don't get itemcommands. When I remove the button attributes command it works.
[Code]....
Obviously I can find a more creative way to add the javascript function, but this was the clearest way. Can anyone determine why adding an OnClientClick even in the ItemCreated would cause viewstate to fail?
Alright, I am completely baffled by this one. When filling out this page in IE8, it will SOMETIMES clear all entered data (including radio choices) when you select Yes, No, or Not sure (line 892 in the code). This is a postback question, as it should potentially show more questions. This problem does not happen in any other browser, and rarely in IE8. I have no idea what is causing it, the code I am using has been used in similar applications and I can't find any change which results in this behavior.

I have a bound data field, a detailsview, one of the records I have formatted to currency in the item template. Yet when I go to delete a record, I get a error message "Input string was not in correct format". Take away the formatting and the page runs fine. I tried changing the datatype from int to money, it makes no difference.
I have a GridView with two templatefields, one with a DropDownList and the other with a TextBox, both loose their values once I hit the "update" button. Is it any way I can make the controls keep the values?
I have a private static field in my Controller class in an MVC web application.
I have a static method in that controller that assigns some value to that static field, I want to apply lock on that static field until some other instance method in the controller uses the value stored in the static field and then releases it.
DETAILS:
I have a controller named BaseController having a static ClientId field as follows and two methods as follows:-
public static string ClientId = ""; static void OnClientConnected(string clientId, ref Dictionary<string, object> list) { list.Add("a", "b"); // I want the ClientId to be locked here, so that it can not be accessed by other requests coming to the server and wait for ClientId to be released:- BaseController.clientId = clientId; } public ActionResult Handler() { if (something) { // use the static ClientId here } // Release the ClientId here, so it can now be used by other web requests coming to the server. return View(); }
I have a AsyncFileUpload and a ImageButton inside the same UpdatePanel. The problem is that, after I upload a file and then click on the ImageButton, the AsyncUploadFile is cleared.
I did some research after posting. All I found was simple examples for no-layer architectures, like connecting to a database from your aspx page, so, in a corporate environment, it is unnaceptable.
I need to call a server-side method (using ASP.NET Ajax) in a 3-layer architecture.
For example, my Default.aspx contains a method LoadProducts().
[Code]....
[Code]....
This cannot change. There is no way to convert Business and Data layers to static.
How can I call the LoadProducts() method using ASP.NET Ajax?
I have an AnimationExtender to popup a div Resizing window for animation
[Code]....
[Code]....
The div [Code]....
The anchor that fires the event <div id="divJumpToActivityManager"> <a id="hypGoActivities" runat="server" href=""><h3 id="picLearnMoreAboutActivities"></h3></a> </div>
So the problem is that the first time it pops up my window fine and animated. The second time it pops up the window and all my markup is gone. Just a blank window. Any ideas how to resolve this so my markup always appears?
just for my testing purpose i know i can define both the connection's outside in a single web config file by different name's and access them in my front end according to it but what if i want to have seprate for both connection's web.config situation is like this see image so i want to access my connections from second web config file how i can do that.
Or any class that's not X.aspx.vb. I've imported the Globalization, Threading, Threading.Thread, and UI.Page namespaces. But it won't come up in Intellisense and it gives error lines in my code. Is there a way to access use the GetLocalResource("Y") method in other classes?
Strange problem, not sure why it's happening. Basically I have inside an UpdatePanel a dropdownlist, a textbox, and a regex validator. page loads, ddl is bound and then based on the value in the ddl, a different regex is applied to the textbox. DDL could have search by "date" (with date regex), "last name" (with az regex), or "zip code" (with a zip regex). This way one search box can be used with 3 different regexes. Select zip code in the ddl, the OnSelectedIndexChanged is fired and the new regex is applied to the textbox. Simple.
The problem is, though, is that the page loads, I select Zip Code in the DDL, type in a zip code and then tab out NOT clicking the search button, and as soon as I do the regex validator fires with the red *. I wait about 2-3 seconds and it appears there's a postback that's fired somewhere because the textbox gets cleared out. Here's the update panel.
[Code]....
There is nothing in the code-behind that causes any postback except the dropdown list that applies the appropriate regex to the textbox.I see no reason why after 2-3 seconds the textbox gets emptied out. Is there a way to stop this?
