Web Forms :: SQL Delete Function Produces BC30506?
Jan 25, 2011
When I try to load a page on my site that has a link that allows users to delete a row from a SQL Database, I get the following error:C30506: Handles clause requires a WithEvents variabledefined in the containing type or one of its base types.
I have a log-in panel that when a user is logged in will show a Log Out button. Only problem is when I go to debug I get the error message:
"error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types."
This is my back-end code:
[Code]....
And this is the front-end:
[Code]....
The log-in button works fine and I was just wondering if any of you could spot what is wrong as it looks like it should work perfectly as it is the same as the log in button.
I have wrote some codes and also i have added delete column with gridview and would like to make it work ,i mean when someone press delete button i want to delete that row.
I put a server side button on the header page. The website is running fine. I use the same source and put it on IIS, it's also working fine but the problem is, i couldn't compile it anymore using my VS studio. It's showing no error so when I go and check the output (after scrolling down a bit and found one line says error). it says
C:InetpubwwwrootAmFraserIntranetheader.master.vb(31,0): error BC30506: Handles clause requires a WithEvents variable defined in the containing type or one of its base types.
C:InetpubwwwrootAmFraserIntranetheader.master.vb(32,0): error BC30451: Name 'keyword' is not declared.
keyword is the textbox on the header page. I also played around with AutoEventWireUp (true/false) and defining onclick event on the server tag but it is still not solving the problem.
I have really stucked at a big problem using the AsyncFileUpload inside a TabContainer. It seems that when I have put the AsyncFileUploadControl inside a TabPanel in the TabContainer and now switch tab manually by clicking I receive an error that is another codefile than the .cs file. I cant understand what is causing this error ?
The Error that is highlighted in the code will be this:
Just knocked up a quick sub site and everything was working great until I put my code in the getquote button and now it shows the below error. Done a bit of searching but everything I find says I need to insert something like: Protected WithEvents {buttonname} As LinkButton

How can i make my own delete method to prevent that the data really gets deleted? i want to set a datetime field when it gets deleted insted of a normal delete. i read about overriding the submitchanges function, but i don't get it to work
Could you teach me how to make girdview pass my object (with all it properties) to my ObjectDataSource delete method please?So far the object received by the delete method has only the datakey value, other properties are null.From this article indicates that this is default behaviour - ttp://www.manuelabadia.com/blog/PermaLink,guid,c72852ae-1fdd-4934-a715-f565ceaf21cc.aspxBut i need the other properties pass to the delete method too so i can do other thing before I actually delete the record.
We are using ASP security on the site, i found months back a tutorial on implementing a pretty simple management page that allows you to create, edit, delete and add roles as well as adding users to roles from 1 page..
It has been working fine, but we added our own security matrix to the site, everything that has to do with the ASP side of the security works as expected and no issues or concerns.. but with our matrix in place, i need to tie the 2 together for 1 thing.. the deleting of a user..
The delete function works great.. but i would like to add my delete to that function so that the users security matrix is deleted as well when their account is done.
Within the class that is handling all the membership functionality, there is this portion tha handles the deleting, i would like to add a call to my class that has the delete method so that when you click delete, the membership account as well as the matrix record is deleted. Since the delete is already setup within my 2nd class, how can i call it to execute it from within the first class?
Sure this is something obvious, but I can't see it.I have an area in my project, UserAdministration. Whenever I call anything in the area I get a 404 error.The AreaRegistration class contains:
[Code]....
The AdminController contains a method for Index.RouteDebug shows the route is to the correct controller (Admin) and action (Index).
When the page loads it works fine. (and lots 10 links) on the update panel it hits the same function and tries to get another 10 links. I set the navigationURL to something like
"../Folder/Mypage.aspx?498592ghjgfosdfgo"
It is set identically both times(load and updatepanel postback) but when i try to render it to html the second time (on the update panel) it adds "../" to the front so i end up with
"../../Folder/Mypage.aspx?498592ghjgfosdfgo"
The function where it changes here
Public Shared Function RenderControl(ByVal c As Control) As String Dim sw As New IO.StringWriter Dim htmlw As New HtmlTextWriter(sw) c.RenderControl(htmlw) Return sw.ToString End Function
c is the hyperlink which has the propertry navigationurl (this never gets changed) but the sw which ends up looking like this on load
List<string> tracks = new List<string> { "ABC", "DEF" }; var items = (from i in Agenda.AgendaSessions select i).Where(p => p.Tracks.Any(s => tracks.Contains(s.Code)));
this returns all sessions which track contains either ABC or DEF, now when I rewrite the statement like the following, it returns All sessions regardless, as if the clause always yeilds into true,
var items = from i in Agenda.AgendaSessions where i.Tracks.Any(s=> tracks.Contains(s.Code)) select i;
Update
if there are other clauses within the where, does that affect the results?
You have used the attribute named above in your document, but the document type you are using does not support that attribute for this element. This error is often caused by incorrect use of the "Strict" document type with a document that uses frames (e.g. you must use the "Transitional" document type to get the "target" attribute), or by using vendor proprietary extensions such as "marginheight" (this is usually fixed by using CSS to achieve the desired effect instead).
This error may also result if the element itself is not supported in the document type you are using, as an undefined element will have no supported attributes; in this case, see the element-undefined error message for further information.
I have a ajax combobox in my page, when i try to select an item from it i can select by typing in text and its selectedindexchanged event fires, but when that event is complete and when i try to select another item from the combobox it produces the following error:

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 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.

I have a gridview with edit and delete parameters enabled. When I click on the edit link, I can edit the record successfully. However when I click on the delete link, nothing happens (the record does not get deleted).

I have a site that is running on a Windows Server 2008 machine with IIS 7.0, when I try to open it with Visual Web Developer 2010, it says the following:
error: unable to open site: ... The Web server does not appear to have FrontPage Server Extensions installed.
Looking on the server Frontpage Extensions 2002 are installed, so what could be wrong?
The thing is, I used to be able to open the project and work on it, etc...
Open Website -> Remote Site -> Enter remote site name -> tries to open & error above!
I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below
I have this import function which can be changed by the client in his desired way.Now I want to code such that if the client tries to import his own data on the page and doesnot give the tags in the order mentioned below his import function should be stopped.
It shouldn't make any changes unless the tags are in the right format because the problem now is if the tags are not in the right format when client changes then its importing over the existing files and directing to an error page which I dont want it should simply stop the import function if they are nt in the order.the code for this function is below
