Web Forms :: Create One Subroutine To Handle All Deletes For Page?
Mar 5, 2011
I am trying to create one subroutine that can handle all deletes for a web app. I have one delete popup panel in my master page, and I call it each time from my content pages. When an instance of delete is called from a content page, I store the name of a delete subroutine specific to the delete instance in a session variable and popup the delete panel in the master page. If a user types YES into a delete textbox in delete popup panel, a confirmDelete Subroutine in codebehind of the Masterpage is called. When the confirmDelete subroutine in the Masterpage is callled, I want to call a subroutine in the content page that has the name stored in the session variable. What is the simplest way to do that?

I have created a page with a gridview in asp.net that displays the records of a database table and allows users to delete checked records by clicking on a delete button. After I delete a record and I try to refresh the page from the browser (I am using mozilla)I get the follow message:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
and if I click resend another record is deleted automatically. Even though I am reloading the gridview after the deletion the application executes again the onclick event of the delete button is executed and the gridview things that there is a checkedbox selected so the code executes my delete function again.
Is there any way to get rid of these behavior. I have been trying quit a few things but nothing works for me.

I would like to create a webpage which can handle user events like page navigation and page close. And also I would like to handle the event on server-side coding.

I am not trying to activate an event or run a subroutine from a control from the masterpage, I am trying to activate or run from VB codebehind of the master page.
I have a button in a content page with a particular .click even that I want to activate from the masterpage codegehind periodically.
Also, how do I access or run a subroutine in a content page from codebehind in a master page.

I am building in error-logging into my site, and want to be able to get hold of the current page name that the error occurred in, as well as the specific subroutine or function, to then pass to a VB.NET function. Is there anyway to get hold of this information without hard-coding the names manually? For example,
Dim strCurrentPageName = ???
Dim strCurrentRoutine = ???

If I have a subroutine in codebehind called:
Subroutine1
and I store it in a session:
Session("tempSub") = "Subroutine1"
How can I then pull it out of the Session and call it?
something like this, but it doesn't work.
Dim tempSub as object = Session("tempSub")
tempSub()
Which would actually be subroutine1() if it actually worked.

The delete link on my gridview deletes the previous row instead of selected row....Also, it doesnot delete the already existing rows. When I add new rows and try to delete them then my delete works that too incorrectly.

I'm trying to pass in an ID of an activity (RefNum) to my codebehind via OnDataBound called in the CheckBoxList, but can't seem to find the correct syntax.
I know I'm supposed to use parentheses when passing parameters to subroutines and methods, and I've tried a number of ways and keep receiving the following error:
BC30203: Identifier expected.
So I tried to hard-code it in the code below [ OnDataBound="FillSectorCBList("""WK.002""")" ], but it's obviously wrong. :(
Front-end:
[Code]....
Code-Behind:

I have a GridView control which is populated by an SQLDataSource. When I select a row the details are shown in a DetailsView control. Is it possible to intercept the select and run a VB subroutine at the same time so that I can make a Panel in a separate part of the page disappear?

I moved a site to another server, it worked fine for a a while, but then crashed. I figured out that System.Web.Extensions.dll was missing, so I copied it again. After a while it was missing again. Using Process Monitor I figured out that IIS (w3wp.exe) deletes the file soon after I copy it to the bin folder. (CreateFile with "Read Attributes, Delete" access.)

Sometimes I am getting a time out exception when reading an XML via a URL. Is there something I can do to prevent this, or is this a problem with the remote server? Below is my simple code:
XmlDocument doc = new XmlDocument();
doc.Load(XmlReader.Create(this.RssUrl));
I do not know how to pass that setting into the code above (or if that is even the correct solution): [URL]
Exception Details: System.Net.WebException: The operation has timed out

I am trying to delete three related objects on one submit. Delete fails on one of the child objects, because of foreign key contraint with another table, It deletes one (the parent) but not the two child objects. All in one SubmitChanges(). I even used the TransactionScope, still same thing. So here is the scenario:
I have an object called Page which has a collection of objects called Webinars. There is another object Called Product which is one to one with Webinar.

I am trying to create a method that accepts multiple types of controls - in this case Labels and Panels. The conversion does not work because IConvertible doesn't convert these Types.
public void LocationsLink<C>(C control)
{
if (control != null)
{
WebControl ctl = (WebControl)Convert.ChangeType(control, typeof(WebControl));
Literal txt = new Literal();
HyperLink lnk = new HyperLink();
txt.Text = "If you prefer a map to the nearest facility please ";
lnk.Text = "click here";
lnk.NavigateUrl = "/content/Locations.aspx";
ctl.Controls.Add(txt);
ctl.Controls.Add(lnk);
}
}

I'm working on a functionality in my asp.net web site that enables the user to download some files as a zip file. I'm using the DotNetZip library to generate the zip file.
My code looks like this:
protected void OkbtnZipExport_OnClickEvent(object sender, EventArgs e)
{
var selectedDocumentIds = GetSelectedDocIds();
string archiveName = String.Format("archive-{0}.zip", DateTime.Now.ToString("yyyy-MMM-dd-HHmmss"));
AddResponseDataForZipFile(Response, archiveName);
try
{
string errorMessage = Utils.ExportToZip(selectedDocumentIds, arkivdelSearchControl.GetbraArkivConnection(), Response.OutputStream);
if (!string.IsNullOrEmpty(errorMessage)).......
Now, if anything goes wrong, say the Utils.ExportToZip method fails, I want to present an error message to the user and not the download dialog. Do I have to remove some data from the Response object in order to cancel the download operation?

I have a set of keywords (about 1000 keywords), and I want to build a wide table, up to 1000 columns:
+each column corresponding to a keyword
+each row will represent an article document, which each cell will be the frequency of the keyword in the document
How to do that in a programmatically way? (e.g., using Linq and C#)

In a base class object, I have an overridable subroutine that I would like all derived objects to have the ability to include. However, they don't have to, and if it's not necessary for them to use it, I don't want them to be forced to declare it. To enforce this, I've left the default behavior empty. For example, here's my whole sub:
Protected Overridable Sub MySubroutine(ByVal someObject As Object)
End Sub
Is this bad practice? I don't want to declare it as MustOverride, but I don't want default behavior. Is there a "better" way of doing this, or is this perfectly acceptable? I don't want to be that hack programmer... just trying to learn :)

I am still at the elementary stages of Linq To Sql and Entities usage. I started practicing MVC developement by following the NerdDinner tutorial here at asp.net, and I back myself up with fully developed NerdDinner sample (1.0 -- still on VS2008). I am also at the first half of the NerdDinner tutorial (I think -- maybe I'm further along) - so far I have gotten up to the Delete View. In the fully developed sample I noted that it uses ascx file (which I guess I will find out if the tutorial also will use
ascx files down the road). My sample app, which I am developing from the tutorial, seems to work OK so far. My issue is that I am not clear how the Delete mechanism works. In the DinnerRepository.cs I have this code (from the tutorial):
[code]....
It looks like a dinner object is being passed to these mechanisms and the delete occurs based on a row ID value. But what if I wanted to delete multiple rows - say where ID between 15 and 20 - how to go about this? I was looking for a Delete statement but am not finding it either in what I have developed so far from my tutorial sample or from the fully developed sample. How can I control Deletes in MVC?

I have a page that has a data grid and about 25 drop down lists.The datagrid displays Name and has an id col not visible. I was thinking that whan the user selects the select link button on the grid to then get all the data for all the ddl and populate the list and select the value or multiple values for that specific name that was selected. Thinking of it seems more like i should populate all the ddl and when a grid name is selected only get the keys for that specifc record and then mark the ddl items per that name. there are lots of ddl and lots of data, im not really sure the best way to proced. Any ideas appreciated.
I have a table with id typeId and Name that contains all of the data for the drop down list (different types of service providers , (plumbers, elec)I was thinking of selecting everything from that table and then in the page applying a filter by service provider type and using that to populate the ddls.

When setting up my database, I forgot to set the delete rule to cascade on foreign keys. Now, I can't delete a user from the ASP.net control panel due to the FK constraints. So, I need to go through all my tables and allow cascade delete on all keys.Once I do this, will I need to redo my Linq .dbml? (ie: delete each table on it and drag it back on) or does it not matter?

I have button, which fires an event, that deletes a record from the database. This is the source of the button:
<asp:Button ID="btnDelete" runat="server" Text="Delete" onclick="btnDelete_Click" />
But how can I make a confirm box appear before the deletion?
