Apr 21, 2010
i have a project that allows users to send requests to another user. When the user views the requests he can select reply. I want to be able delete the item after the user selects reply
I have an asp.net 2.0 web app and one of the pages uses a grid to add/edit items before exporting the contents to excel. The items in the grid are selected based on a dropdown list--after the item in the list is selected, the grid goes and gets the items, populates a dataset and binds the dataset to the gridview. Some of my users are experiencing an issue where after deleting a random number of rows, a row not deleted will disappear or reappear. Though I have witnessed the behavior, I cannot duplicate it on my machine where the developement occurs (Win XP Pro, IIS 5.1, vwd2005 express). The windows 2003 server uses ASP.Net 3.5
Here is the code related to editing and deleting:
[Code]....
If I had to make a guess as to what was occuring, I would say that it appears at times to retain the deleted item's index after the grid is sent back to the user and tries to delete another row. But like I said, I can't duplicate the problem on my dev machine. if this might be caused by .Net 3.5 trying to run a 2.0 site?
I'm using the asp.net membership on my website. On the User Administration page i've got a GridView to show the details of the users on the site. As a datasource rather than just using the Membership.GetAllUsers function i've got a SQLDataSource as i need to display user information from 3 different tables. I'm trying to add a delete button to the GridView. I'm setting the Membership's UserName as a DataKey and then using the RowDeleting event to call Membership.DeleteUser for the appropriate UserName. This works fine and the user is deleted however i then get an error showing up that "Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified."
I don't want to use the SqlDataSource for deleting as i've already done it using the Membership. How can i stop it from trying to do this? Here is the cut-down that i have if you're interested. The selectcommand in the sqldatasource was auto-generated by it.

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.

In one of my Web Page, there is one Modal Pop up, in which I am using Gridview Edit, Update, CancelEdit, Delete functionality.Main functionality is : If while deleting any of the Gridview Row, if only 1 row remains in Gridview (that row can be any row), then that row should not get deleted.Rest of Edit, Update, CancelEdit functionally is working fine.
problem is: When any last row is left in Gridview, its Delete button is disables that time (as per requirement and functionality). But when user clicks on Gridview "Edit" button, update section opens, and at that time "Delete" button gets Enabled, so that time user can delete the last row of Gridview which should not be done.I had fixed this problem for "Cancel" and "Update" button of Gridview using below line:
Response.Redirect(Request.Url.AbsoluteUri); but unable to fix it for "Edit" button of Gridview. If Last row is left in Gridview , and user clicks on Gridview "Edit" button of that row, then at that time "Delete" button should not get "enabled" it should remain "disabled"
