Access :: Data Type Mismatch While Inserting Into A Number Field In An Access Database Using A Parameterized Query?
Jun 9, 2010I have a data type mismatch while inserting into a number field in an access database using a parameterized query.I think this should be pretty simple but I am still learning a lot.

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.
Forms Data Controls :: Deleting A Record On A File With Multiple Keys / Access The Rest Of The Keys?
Feb 8, 2010I have a DataGrid that I need to be able to use to delete records form a file
[Code]....
[Code]....
I use
((TextBox)GridMenuOptions.Rows[e.RowIndex].Cells[1].Controls[0]).Text;
To access the data in the Grid for updating, but it doesn't work for deleting
I can use

but that only returns the first key.
How do I access the rest of the keys?

View 4 RepliesForms Data Controls :: Access Data From Unbound Field?
Apr 6, 2010I think it's very simple but i just don't see it at this point: I have a detailsview that's bound to a sqldatasource. I want to have access to the data in a field in the table thats not currenty bound/used in the detailsview. I have a table which has one collumn that contains a username of the user who submitted the record. This field is not bound in the detailsview.I want to have the detailsview show delete/edit buttons only if the current identity matches the value in this collumn of the currently bound record. But i don't want to show this field as a row in the detailsview. I thought maybe i can access this field in the databound event of the dview and create/show the buttons here. But how can a access this data if it's not used in a dview field? I also tried creating a templatefield for this field and set it to visible = false. But then i also can't access the data it seems.

C# - Deleting From Repeater Item - Erroneous Deleting?
Sep 27, 2010I have a repeater which binds a set of data. Within this repeater is a column with various controls for updating, deleting, etc. These are image buttons which fire an onclick event such as "DeleteRecord". All this does is fire a stored procedure, passing in the ID of the record to delete from the CommandArgument of the object.
This works wonderfully... except for one rather huge problem. Once you delete a record, if you refresh the page, the record where the first deleted record used to be gets deleted. For instance... if I have 4 records
1 Record1
2 Record2
3 Record3
4 Record4
and I delete record 2... The page reloads with (which is fine):
1 Record1
3 Record3
4 Record4
...if I then hit refresh...
1 Record1
4 Record4
I assume this is because the erroneously deleted object (record3) is now in the same hierarchical place as the old object used to be and .net therefore doesn't know the difference, the page refreshes and fires the onlick event, grabbing out the command argument of the new object and deletes based on the ID as obtained from the commandargument of the new object. This is obviously a huge problem, if a client did this it would destroy data erroneously and I'm at a loss here. Is there any way to stop this from happening? I'm not sure if there is a better way to go about doing things or not. If there isn't, I need some sort of way to tell the page not to execute the event or to cross reference the ID of the object that is intended for deletion against the object itself...
Code below for convenience...
EDIT Wrapped a LinkButton around it because I have some jquery code in here as well which stops the page execution to wait for user confirmation. Pressing "ok" continues page execution.
<asp:LinkButton ID="oDeleteLink" CssClass="oDeleteIcon" CommandName="Delete" CommandArgument='<%# Eval("iAccountID") %>' runat="server">
<asp:ImageButton ImageUrl="/files/system/icons/trash-steel-16.png" ToolTip="Delete This Account" AlternateText="Delete" ID="oDeleteIcon" runat="server" />
</asp:LinkButton>
protected void oAccounts_ItemCommand(Object Sender, RepeaterCommandEventArgs e) {
if (e.CommandName == "Delete") {
int ID = e.CommandArgument.ToString().Numeric();
db.SPs.SpDeleteAccount(ID).Execute();
UI.Confirm(uiBroadcast, "Account has been deleted", "300px");
BindAccounts();
}
}
