Forms Data Controls :: GridView RowDeleting Is Called Twice?
Oct 20, 2010I 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:

The Code-behind:

what triggers the second Row-Deleting event?

Forms Data Controls :: Delete Confirmation Box In Gridview With Edit And Delete Buttons?
Nov 18, 2010How 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?

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.

Forms Data Controls :: How To Insert Delete Confirmation Dialog To Gridview Delete Button
Apr 6, 2010I am using Sharepoint Designer and trying to insert a Delete button into a gridview. I added this to the top of my ASPX:

and I added this as a Gridview column:

ControlMode="Edit"
/>
and this is the error I get:

Forms Data Controls :: GridView1.RowDeleting Event Occurring For All Command Fields (Edit & Select)
May 11, 2010I'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

Forms Data Controls :: When Gridview DELETE Bombs?
Dec 7, 2010I have several "standard" GridViews in the "admin" side of a web site I am developing. In the past, none of these have ever shown any problems with a standard Delete.
To review: Each of the subject tables has a "RowID" field specified as Identity and as the Primary Key.The BoundField for the Rowid is set to ReadOnly. There is "Edit, Delete, Select" specified for the CommondField. Edit and Select operate as they should.
HOWEVER, Delete results in a "Must declare the scalar variable "@RowID" (with the associated "unhandled exception" verbiage).

DELETE FROM [Events] WHERE [RowID] = @RowID

Forms Data Controls :: Gridview Clearing Out After Delete?
Mar 4, 2010I have a gridview which at run-time contains X number of records. Upon clicking a DELETE linkbutton on a particular row the gridview completely disappears from the page, when it should reflect simply the loss of that one record. Everything is okay on the database end, the record is deleted, so I know that part is working. I run a query and rebind the gridview within the Rowdeleted event. I even try hardcoded a value in the query which I know exists in the database and it still doesn't refresh with this record showing. Whatever code I need to post, let me know.
