In uploading files and determining their length, I want to know if there is any alternative to
<code>
file1.PostedFile.ContentLength
</code>
It seems that this quantity is counted up as the actual uploading is taking place.
Once the customer has selected his file-to-be-uploaded and put it in the textbox, is there any
other way for my script immediately to say "This file is 5 Mb and it is therefore too big" ?
find a good tutorial for uploading files to a virtual directory?
I have been googling for a while now.
I found is this:

But I need code examples, more specific information about security in IIS etc.
I am using a datapager on a page where different images are shown. Now i am using the following code:-
PHP Code:
<asp:DataPager ID="DataPager1" runat="server"
PagedControlID="lvPhotoViewer" PageSize="1"
onprerender="DataPager1_PreRender">
<Fields>
<asp:NextPreviousPagerField ButtonType="Link"
PreviousPageText="<< Previous" NextPageText="Next >>"/>
</Fields>
</asp:DataPager>
Now this code does run through all the images, but i need to alter the querystring and make it change to match the ID of the photo displayed. I tried adding QueryStringField="String" but this was hopeless.
I have a querystring like so:-
Quote:
[URL]
When i click on next image i need it to change to something like:-
Quote:
[URL]
See the PhotoID has changed. But it currently does not do this. When i arrive on the page the PhotoID stays the same. I have been trying for a while and im starting to give up!
So was wondering if there was an alternative.
I am developing a new project to list files and directories under an specified location on disk. I use normal methods like Directory.GetFiles() to achieve this task but the amount of files is getting very big (> 300000) and the site is becoming terrible slow.
I worked with Index server with previous versions of Asp.Net but I was wondering if there is a new way for my website running Asp.Net 4.0.
Also I heard something about Index Server is obsolete to achive file listings and search. Is there any new alternative?
Is there any alternative of Crystal Reports. I dont want to use it....Crystal Reports are just useless,But I didnt get any other alternative!
View 4 RepliesQuick question: Is there a "per-user" data storage object (similar to Session) that I can store data in the global scope (similar to HttpRuntime.Cache)? Almost as if Session and HttpRuntime.Cache had a baby.
Full Background: I have a ASP.NET website that was originally written for a single thread. Now I changed it so that certain actions will spawn a background thread and the browser polls a service to get status updates.
The problem I am having with this is that certain pieces of data are stored into the HttpContext.Session[] object (membership authentication token, for example). These pieces of data need to be unique to each user and accessible to the background thread. Session is not available to the background thread.
I am aware of HttpRuntime.Cache but that would require micromanagement to segment out the users and to expire it at the same time the session is expired. Session, on the other hand, automatically expires this things at the right times that I want it too and is already used by things like the SqlMembershipProvider.
My question is, is there something that behaves similar to the Session but exists in the global scope?
I am working on a Report Module for a DNN website and have found that the reports do not show in the reportviewer control if there is no ScriptManager control on the module. I am not sure where but somewhere I read it was needed. THe problem is when it is on the module so the reportviewer works correctly I am getting some errors with my other controls( mainly drop downs I want to use for selecting the reports) I am not getting an error just the DDL is not showing up on the page when scriptmanager is included but it does show up when its not included of course then the reportviewer shows no report.

I create a menu control in a user contol, named as RightUserrControl.ascx.
and i kept this RightUserrControl.ascx in nearly in 200 pages.
every thing is working fine , but when ever i am going to any page the page loading is very slow, nearly each page is taking 1 minute to load.
set caching for the user control, if this is the case , do i need to declare output cache in all 200 pages or is there any alternative way to resolve this issue.
As a workaround for the fact that asp:Checkboxes don't have values, I am attempting to dynamically create the ID's of checkboxes in a DataList so that it inserts the primary keys into the control ID. This is surprisingly difficult.
I have placed a PlaceHolder in my DataList ItemTemplate, then in the ItemCreated I create the checkboxes using string.Format("Checkbox{0}", DataBinder(e.Item.DataItem, "ID")). The problem is that this only works in a non-postback condition, as on postback the DataItem is null. And of course ItemDataBound isn't called on PostBack so that won't work either.
I can't seem to find a good way to handle this short of if (IsPostback) dataList.Bind(), which i don't think is a good way to do it.
Can anyone provide me with any alternatives here?
In my Application I am using one Modal popup extender. I have one Grid View with Item Template containing Link button. I want to set Target Control Id of Popup extender to link Button of the Item Template. As it is inside the Item Template I can not access it directly in the page.

I am trying to freeze my gridview header for last 2 days and got this link and many other links too provided to me on Stackoverflow as well as from googling. This worked fine when i used it on IE 6,7 and under compatibility mode in IE8 but in normal mode, this code is not working.
This line is giving me an error. I want to implement this functionality.
trs[x].style.setExpression("top", "this.parentElement.parentElement.parentElement.scrollTop + 'px'");
On reading comments, I came to know that scrollableTable.js uses setExpression Method which has been depreciated in IE8.
How to replace setExpression method with some other alternative in this code

I have a table with 4 columns: ID, signId, storeNum, quantity with ID, SignId, and storeNum as composite primary keyif storeNum is -1, that means the quantity is the default quantity. If a store has a store-specific quantity, the storeNum is this store's number.
I need to show all rows that have specific quantity for a store, and all rows that have default quantity and of which the store does not have store-specific quantity
currently I use table-value function with storeNum as parameter to return the list. first, I get all rows that have specific quantity for a store; then, I use cursor to loop through all rows that have default quantity and check each row if the store has a specific quantity. It takes 9 seconds to run the function for a store.
The function is called within a stored procedure, which in turn is called by a function in a class, which in turn is called by a aspx code behind file. It takes about 20 seconds to load the page. 20 seconds to load a page is too long. I am trying to improve
the performance.
I wonder if there is an alternative method to the cursor to get the second part of the list.
i have just found that i cant create postback triggers on the fly (i had a function that runs onclick that creates buttons and postback triggers)
so i need an alternative or a method to achieve this
what happens is onclick of a button, updatepanel1 is updateded and depending on what button you click in panel1 more buttons are added, these buttons that are added also have an oncllick event that should update a wysiwyg in panel2 with content
heres my code below, if anyone has any ideas or knows of other methods to get this to work it would be great

View 4 RepliesI need to upload images from client to server as follows:
1. Server is passing the client a file name
2. Client is checking file extensins to ensure it's an image then issues a __dopostback to the server.
3. Server uses the FileUpload control to save the image on the server.
I have that all covered, but, if image is too large, the upload fails with the following error: 'System.Web.HttpException: Maximum request length exceeded.'
Is there a way to check file size on the client (without the use of ActievX which also errors out), before it is passed back to the server?

I have a problem with selecting a control from codebehind.
This is my scenario:
1. i get a string from a webservice (session): string boxstring = "<input type="text" id="MainContent_TextBoxStopRoadName01" name="ctl00$MainContent$TextBoxStopRoadName01">";
2. i insert this string to a <div id="boxcontainer"> from codebehind like this:
boxcontainer.InnerHtml=boxstring;
3. Page loads
4. User types text in the box, and clicks a button to submit it
5. How do i find this textfield from codebehind from its id? I would like to get the field as an TextBox control, but the text value is the most important.
I´ve tried several things, like Findcontrol("id") and Findcontrol("id").Findcontrol("id") and so on. But it doesent work.
Another thing does work though, if instead of a string I create the textfield as an TextBox control, and then insert it: BoxContainer.Controls.Add(TextBox); - then it works! But it is not a possible solution in my situation. I only have the textbox (among many other elements) in a string.
I have a hierarchy in my website project as below:
[CustomControl1 - folder]
- CustomControl1.ascx
- CustomControl1.css
- CustomControl1.js
I load css and js files dynamicaly based on which controls are used on particular page. I am doing it by using following code:
[code]....
where AddLinks method adds HtmlLink controls to Page.Header with href attribute set to coresponding css and/or js file.
I would like to add Interface that would force new controls to have AddLinks method but it is impossible since it is a static method. Because my custom controls inherit from Control class I cannot use abstract class and/or virtual methods either. How can I achieve my goal?
