Forms Data Controls :: GridView RowDeleting Is Called Twice?
Oct 20, 2010
I have a GridView and provide the user with sorting, paging, editing, deleting and selecting functionality.
When the user klicks the delete-button in the GridView, the Row-Deleting event is triggered, the record is correctly deleted from Database after user confirmation. Then the Row-Deleted event is triggered and afterwards the Row-Deleting event is triggered AGAIN, resulting in a second user confirmation and a Delete-instruction running into void if the user confirm again the question.
Between the Row-Deleted event and the second Row-Deleting event I saw the GridView binds his data again (comprehensible because it wants to provide an updated view to the data), maybe somwhow there is generated or provoced the second Row-Deleting event.
My GridView:
[Code]....
The Code-behind:
[Code]....
what triggers the second Row-Deleting event?

I'm creating a confirm delete like popup with an iframe to use along with a gridview. When you click delete on a gridview row, the iframe shows up and asks if you would like to delete the associated image as well from the server. It works perfectly the first time I delete a row. After that whenever I click select or edit on a new row, it calls the rowdeleting event from the last deleted entry every time. I'm stumped.Here's the Sub:
'// Event that Occurs when the Delete Button is Clicked //'
Protected Sub Confirm_Delete(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting
Dim file_name As Array = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "/")
If file_name.getLength(0) = 1 Then
file_name = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "")
End If
Dim fn As String = file_name(file_name.getLength(0) -1)
fn = replace(fn, ",", "%2C")
fn = replace(fn, " ", "%20")
Dim url As String = Me.Master.get_root_url & "CrimeBulletinProject/ConfirmDelete.asp?img_list=" & fn & "~!"
confirm_delete_frame.Attributes.Add("src", url)
confirm_delete_frame.Attributes.Add("style", "display: block; left: 50%")
End Sub
Here's the GridView:

I have a GridView with a delete button next to each row. When I click the delete button, I want it to delete the file listed in the 'News_Image1' column of the table. However when I try and recall this data by using e.Values, it doesn't work, and returns nothing. I have also tried e.Keys and e.Command.Parameters. My code is as follows:

How can I get data from a specific column in the record that I am deleting in VB?

I have been researching this issue for a couple of days and have found a lot written about it, but none of what I have found has fixed the problem I am having.
I work for a school system, and my principals are wanting to take a list of the staff members at their school and create staff lists for different activities they perform. I thought I would load the staff into Gridveiw1, and when they select a record have it move over into Gridview2 and "delete" from Gridview1.
I am loading my full staff into a datatable (SQL Server backend), and setting this datatable as my gridview1 datasource. At this point, it loads great, and cosmetically speaking sorts and pages fine. The problem occurs in the codebehind after a Sort or Page change has occurred -- when I select a record and move it over into Gridview2, it is moving the original record that was at that postion on Page 1 instead of the sorted or "new page" record.
So if the initial list comes in as:
Teacher 1
Teacher 2
Teacher 3
The sort button is hit so that the list now starts out like:
Teacher 7
Teacher 13
Teacher 5
If they select "Teacher 13" to be moved over after the sort, instead it is still moving over "Teacher 2" -- the initial teacher in that index before the sort.
The Gridview setup on my aspx page looks like this:

I have a Data Grid View which display values from a SQL Query, and inside the data grid view I have two template fields one is Quantity and it is a text box and the other is Total Price and it is a label.
What I want to do is to insert a button called update and when I press this button the price Column should be multiplied by the quantity Column and the result should be displayed in the total Column.

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:
1- footer
2- Toolbar Control
3- Scrolling Data Grid with Header
ListView give us only one ItemPlaceHolder to Bind Data as per LayoutTemplate, so I cannot able to manupulate my Toolbar Controls with ItemTemplate :(, therefore I decide to use ItemDataBound to add ImageButtons Dynamically using Init Page Event and I am able to get the result as you saw above:
ImageButton with funnel icon is with CommandName="Filter"
ImageButton with magnifier icon is with CommandName="View"
ImageButton with stop icon is with CommandName="Delete"
Now I can able to handle Filter and View with OnItemCommand Event but when I click Delete button I am getting an error as shown below: The grid used CSS I am sending you the HTML and code behind to resolved this problem: HTML CODE:

I'm using Sqlreader to get some information from a database table. Right now I have it looping through a while loop, and adding in the appropriate information in to an asp table contol. I'm not haveing any difficulty with that, what I am having problems with is sorting the data. I just want it to sort it by a field called title. I tried putting an ORDER BY statement into my SQL command, but it throws an error saying it cannot sort a text field. So the only thing I can think of is instead of adding the data right from the sqlreader to the table control is that I first put it into an array, sort the array, and then add it to the table control. It seems like an ineffieint way of doing it. Is there a better way of sorting this stuff or is there a way to get the database to do it for me like with the ORDER BY command?
