VS 2008 Delete SQL Row(s) Automatically Without Human Intervention?
Jun 23, 2010
Is there a way to delete a SQL row automatically, without human intervention? I plan to use this concept on advertisements. A user or guest can post his/her advertisement in my site. That advertisement should only last for a specific amount of time, let's say 30-days. After 30-days, the application automatically deletes the said advertisement without me, or any other person, doing anything. I've been searching for a solution these past few days, but it seems I can't find the right words to use in Google.
I have a GridView and a SqlDataSource, which I have set to automatically generate Delete/Insert/Update statements. I then just enabled Deleting on the GridView, and usually away I'd go. For some reason though, the row is not being deleted - the page is posting back but the row is still there. When Delete is clicked, RowDeleting does fire though. What possible causes could this be?
Edit: SELECT command: SELECT id, templatename, CASE WHEN type = 'W' THEN 'Weekly' WHEN type = 'M' THEN 'Monthly' WHEN type = 'Q' THEN 'Quarterly' WHEN type = 'S' THEN 'Six-monthly' WHEN type = 'A' THEN 'Anually' END AS TypeText, CASE WHEN invorcred = 'I' THEN 'Invoice' WHEN invorcred = 'C' THEN 'Credit' END AS 'InvOrCredText', nextinvdate, lastinvdate FROM InvoiceTemplates WHERE (sageaccount = @sageaccount)
I am moving a site from one godaddy account to another godaddy account. Same ASP.NET 4 IIS 7 settings.
What I notice is that all the friendly urls like home.aspx _login.aspx_ return a 404 ERROR, as if the rewrite was not working. As a desperate attempt, I switched from urlFormat="humanfriendly" to urlFormat="searchfriendly" and it started working. But humanfriendly, that allows short and clean urls won't work at all.
I have a gridview control in which there is a column with checkbox. I will have to delete the rows of the grid selected by the checkbox. After the delete operation i am re-binding my grid we new datasource to populate latest data. The data is comig up correctly and the no of rows in the grid are also correct.
But the problem is that, if i select row 1 to delete and click on delete button, row 1 is deleted, grid is refreshed with new list, but row 2 checkbox is getting automatically checked. I don't know how this is happening. I have tried of writing code to uncheck all checkboxes after i rebind the grid. None of them are working. When i debug and see the items are actually showing as checked=false, but on the screen the check box is checked.
This is kind of cross-post; however, can a custom http handler be automated to run either using a timer or a filesystemwatcher to post an xml document to another server (with no human interaction)?
I can open the modalpopup, can close the popup, but if i click the "edit" button to edit any of rows, the popup closes automatically. If I click again, the "Update" and "Cancel" buttons shows, and after clicking one of those, popup closes again. The above code works, if i use gridview the insert, edit or delete the data, does not close automatically. What may be the cause of this problem.
So I am a beginner with .NET, Visual Studio, C#, etc. But I am wondering something about the code behind a form and a difference I am seeing in 2008 versus 2005. So lets say I have a simple Windows Form app, C#, and I throw a couple controls on it. Then I add some MessageBox.Show event handlers for the default events....in 2005 there is that little section within the code that is hidden that basically contains the code that 'registers' the controls with the system....I think. That may be a bad definition?? Basically I think that automatic code generated here just basically associates the event to the event handling code....anyway.
I can see this is 2005 (once I click the like gray box), but it does not appear anywhere in 2008. So this has to exist somewhere, and I just wanted to ask to be familiar with what is going on since I am new to this. I still have to figure out how to turn on the code line numbering in 2008, but I can google it.
the application which i created is a web application which doesnt need much of a database,so i am just using the sql express free version which allows 4 gb of data,to avoid disasters iw ould like to delete records which are very old like,1 month,2 months old etc,how can i do this periodically should i do this on client side or the server side...

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.

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).

My source codes for both the UI, BLL, DAL is shown below
