How To Delete / Add More Session Value To Repeater
Nov 2, 2010
I've got this problems n till now i could not find the answer. I create an custom cart application, and the problem occur when I'm trying to solve the final page. This cart model like a wizard, it means there are pages to be passed before getting to the last (Cart) page.
The problem here is, every value which is checked/choose in the beginning pages are saved in Session (Session["CurrentCartItem"]). And in the final cart page, the collected value in the "CurrentCartItem" Session is inserted to the "repeater". Now the question is, how can I add more values in the repeater (which is returning again to the beginning pages) without the value which showed in the repeater is gone?
And how can I delete one of the values from the repeater ? FYI, I'm saved all the value using the Session, not database.

I have a Silverlight application using a WCF service hosted in IIS. I make use of some aspects of ASP.NET. I have the following folder structure for my application:
inetput
wwwroot
myapp
reports
{user-guid-folders}
report1.pdf
report2.pdf
App_Data (folder)
bin (folder)
Client_Bin (folder)
(various .aspx files, plus web.config, etc.)
The application dynamically generates reports and puts them in a folder with a GUID for the name which is unique to the user. This all works fine. However, when the user logs out I was cleaning up and deleting the PDF files in their folder, then deleting their GUID folder.
Deleting the files works fine, but if I delete the folder, the application recycles (which then removes all other users' sessions - I get a Session_OnEnd event for every user's session, and an Application_OnEnd event. The next user request causes the whole application to restart. So, while I can fix this by not deleting the GUID folder (which my application itself created), what is the reason for this? Is there any way I can prevent this from happening?

I use the simple code in onunload's body method like this:
<body
onunload="closeIt()"> ... </body>
The closeIt method is call a server method, like this:
function closeIt ()
{
$.ajax({
type: "POST",
url: "mypage.aspx/myFunc",
data: '{}',
contentType: "application/json; charset=utf-8",
dataType: "json",
//async: false,
success: function(response){},
failure: function(response) {
alert(response.d);
}
});
}
I delete a folder in temp directory in myFunc method. The folder's name is the same of value in Session["id"], like this:
string id = Session["id"];
string temp = "~/temp" + id;
temp = Server.MapPath(temp);
DirectoryInfo dr = new DirectoryInfo(temp);
Directory.Delete(dr.FullName);
When the last code( Directory.Delete(dr.FullName) ) is run, the all session in project is changed to null. If i disable the last code( //Directory.Delete(dr.FullName) ) every thing work properly(all session have the value). Why when i enable the last code, all session are null? What's the problem and how can i solve it?

I am writing a chat application, in which a chat starts in a chat room. Now, i want this room active only for a certain amount of time and not more. i.e 1 hour etc. So, to check the time constantly what and how should i write something in the background, so that when the time is over, the sessions of all the users logged in at that chat room get destroyed. And the users are again redirected to the login page. e.g The chat has been setup from 3 to 4 pm. At 3.55 everybody should be given a popup that the chat will end in 5 mins. And at 4 everybodys session should be destroyed and they should be redirected to the login page.

first off I can't post the code, so I will do my best to try to explain what I am trying to do. I have a repeater with three literals (a member ID, a name, a uservalue) and three hyperlinks. Each of the hyperlinks goes to a different page (obviously).What I am trying to do is when the user clicks on one of the hyperlinks, (doesn't matter which one because the three literals need to be put into session variables regardless) I want the session variables set to the literal values before calling the next page.How do I get the session variables set when the user clicks on one of the hyperlinks?

I have a file delete option for the files uploaded by the user, user can upload many files at a time.The uploaded files will be stored in a folder in server and when its is deleted its is moved to trash folder from where it will be manually cleared.
when a user tries to delete many files in the web page IIS get hangs and all session is expired. This case only present in server,in local host this issue is not available.
ALL the operations is carried out completely ie
Database gets updated. Files is moved from upload folder to trash folder in server.
I cannot determine what is going wrong,I just tried to delete many files totally around 35-36 MB. Is the issue with process taking long or is there any changes have to be made in order to perform large files operation, my project is done on VS2005 which is running in 2008 server.

I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Below is the code to fill the grid, paging and fill repeater on rowdatabound event of grid.

How do I reference the delete button to add the delete confirmation box when I have both the Edit and Delete buttons as the last two columns in the Gridview control. The following code works fine without any issues when I have the delete button only:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.DataRow) return;
int lastCellIndex = e.Row.Cells.Count - 1;
Button db = (Button)e.Row.Cells[lastCellIndex].Controls[0];
db.OnClientClick = "if (!window.confirm('Are you sure you want to delete this record?')) return false;";
}
But, when I have both the Edit and the Delete buttons, I get the following error when I click the edit button while the delete button works fine.
Specified argument was out of the range of valid values. Parameter name: index
How do I reference the delete button so the edit button is not affected in this case?

Using "Enable Delete" from Gridview control, I can delete (besides, update, sort, paging, etc) data from the database (this is done automatically). However, how can I delete the actual image that resides in my image folder (i.e. from "pix" folder )? What is the best way to delete image? If using code behind, how? Please write a full code for me. Here is my source code.

I am interested in building an intranet document management system to be used from Internet Explorer using ASP.net, VB.net, and MS SQL Server but have no experience in doing a project like this. Supported file types would be txt, pdf (from scanner or imported from file system), or jpg. What concepts I should look at researching/learning about to build the system in a way that files will be stored as small as possible, retrieved and displayed quickly, and secured. The users would be spread out over a regional area covering 4 states.

I have a grid contol that allows delete what I would like to have is someway to say Are you sure you want to delete?I found this code online, and tried it but it did not work, Do I need something more some behind code maybe?Here is what I found online:Adding 'Delete Protection' to controls If you use a control set up to allow Delete, the Delete button gives a straight delete without any warning, which can be dangerous.To give a warning dialog box, add an OnClientClick event to the Delete button, as follows.
<asp:LinkButton
ID="DeleteButton"
runat="server" CausesValidation="False"
CommandName="Delete"
OnClientClick="return confirm('Are you sure you want to delete this record?');"
Text="Delete">
</asp:LinkButton>
Here is my code: You can see where I added the code from above.
<ItemTemplate>
ID:<asp:label id="IDLabel" runat="server" Text='<%# Eval("ID") %>' /><br />
Name:<asp:label id="NameLabel" runat="server" Text='<%# Bind("Name") %>' /><br />
Destination:<asp:label id="DestinationLabel" runat="server" Text='<%# Bind("Destination") %>' /><br />
OutDate:<asp:label id="OutDateLabel" runat="server" Text='<%# Bind("OutDate") %>' /><br />
ReturnDate:<asp:label id="ReturnDateLabel" runat="server" Text='<%# Bind("ReturnDate") %>' /><br />
LeaveTime:<asp:label id="LeaveTimeLabel" runat="server" Text='<%# Bind("LeaveTime") %>' /><br />
ReturnTime:<asp:label id="ReturnTimeLabel" runat="server" Text='<%# Bind("ReturnTime") %>' /><br />
ContactNumber:<asp:label id="ContactNumberLabel" runat="server" Text='<%# Bind("ContactNumber") %>' />
<asp:linkbutton id="EditButton" runat="server" CausesValidation="False" CommandName="Edit" Text="Edit" />
<asp:linkbutton id="DeleteButton" runat="server" CausesValidation="False" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete this record?');" Text="Delete" />

I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:
<%@ Register Tagprefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls"
Assembly="Microsoft.SharePoint, Version=11.0.0.0, Culture=neutral,
PublicKeyToken=71e9bce111e9429c" %>
and I added this as a Gridview column:
<SharePoint:DeleteItemButton
runat="server"
ID="CustomFormDeleteItemButton"
ControlMode="Edit"
/>
and this is the error I get:
An error occurred during the processing of . System.Web.UI.WebControls.DataControlFieldCollection must have items of type 'System.Web.UI.WebControls.DataControlField'. 'SharePoint:DeleteItemButton' is of type 'Microsoft.SharePoint.WebControls.DeleteItemButton'.
