Hello all. I have a GridView and a DetailsView which is bounded to the first one, so that when I click in the Grid's "select" command, it shows the related data in the DetailsView. So far, this is working smoothly.
However, now I have a table with two primary keys. I changed the declaration of my asp:GridView tag and edited the DataKeyNames to include both primary keys. So I run the ASP.NET. So far, I have this data:
PK1 PK2 DESC
=========================
1 1 Desc1
1 2 Desc2
1 3 Desc3
where both PK1 and PK2 are primary keys. The grid shows the data correctly. When I select the first item, the DetailsView displays the data correctly. However, when selecting the second or third row, it does not select anything (furthermore, not even the controls --textboxes-- are shown).
So I believe it has something to do with the fact of having two primary keys, even though I specified them in the GridView control.
I'm I missing something here? Has anybody ran into the same problem? A clue? I've googled and so far I've found sites saying that multiple primary keys are allowed, yet they do not remark any particular aspect for doing so.
Thanks in advance.

So, I solved it. What I did was to capture the GridView's SelectedIndexChanged. There, I placed the following code:
DataKey dataKey = CatalogGridView.SelectedDataKey;
_detailsDataSource.SelectParameters["IdAtributo"].DefaultValue =
dataKey["IdAtributo"].ToString();
_detailsDataSource.SelectParameters["IdRol"].DefaultValue =
dataKey["IdRol"].ToString();
_catalogDetailView.DataBind();
where _detailsDataSource is the... well, the data source associated to the DetailsView _catalogDetailView. Before this, I had the following declaration of my data source's select parameters:
<SelectParameters>
<asp:ControlParameter Name="IdAtributo" Type="String" Size="5" ControlID="_catalogGridView"/>
<asp:ControlParameter Name="IdRol" Type="String" Size="5" ControlID="_catalogGridView"/>
</SelectParameters>
While this works perfectly when having only one primary key (the GridView passes the selected index to this data source and hence the DetailsView is updated automatically), for some unexplained reason it is not working with multiple primary keys. Thus, I just passed the values manually in the GridView's SelectedIndexChanged and DataBinded the control manually.
Now it is working perfectly. Notice however that the parameters cannot be of type asp:ControlParameter, but rather they must be simple asp:Parameter.
Thanks anyway.

Hello All,
I have a boggling question (For myself anyway)
First of all, here is the code.
If Not FILE1 Is Nothing Then
If Not FILE1.PostedFile.FileName = "" Then
Dim sFile As String
'sFile = UID & "_" & Replace(FILE1.PostedFile.FileName.Substring(FILE1.PostedFile.FileName.LastIndexOf("\")), "\", "")
sFile = UID & "_" & FILE1.PostedFile.FileName
'spath = Server.MapPath("\files\") & UID & Path.GetFileName(FILE1.PostedFile.FileName)
FILE1.PostedFile.SaveAs(Server.MapPath("../Files/" & sFile))
sql = "update events set eventfile='" & sFile & "' where eventid=" & UID
myCom = New SqlCommand(sql, myCon)
myCom.ExecuteNonQuery()
Else
sql = "update events set eventfile= '' where eventid=" & UID
myCom = New SqlCommand(sql, myCon)
myCom.ExecuteNonQuery()
End If
End If
The problem is, most machines (All to my knowledge with the exception of one) work fine with this code. They can upload files with no problems, shove the path in a DB, and carry on like normal.
One client cannot. The error she recieves is looking like instead of passing the filename as sole, it is passing her local filepath as well..
Here is the error:
Server Error in '/' Application.
--------------------------------------------------------------------------------
'../Files/210_G:\OH&S Certification Training\Marketing Info\Spring 2008.doc' is not a valid virtual path.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Web.HttpException: '../Files/210_G:\OH&S Certification Training\Marketing Info\Spring 2008.doc' is not a valid virtual path.
The String '../Files/210_G:\OH&S Certification Training\Marketing Info\Spring 2008.doc' should simply be '../Files/210_Spring 2008.doc'
Any ideas on why this client is having such a problem? All help is greatly appreciated.. and if possible I would email some brewskies. 
Thanks in advance.

Are you using the inbuild extender controls?
If not, have you created your own extender control?
Do let us know this info so that we can move forward..

Hi,
1. Tell me, when you created your report, did you use the dataset that you created, or did you connected directly to the database?
2. When creating the Dataset, dropping the tables from the database on the dataset, have you deleted the fill objects at the bottom of the table?
3. Have you created an instance of your dataset and fill the tables in the dataset with the code from the database?
4. Lastly you have to set the datasource for this report to the dataset instance that you created and filled.
Let me know if you need assistance. I struggled myself with this in the beginning.
Kind Regards,
Elizma

Look at this
Table Name Attributes<br />
ID 1<br />
qty1 1<br />
price1 20<br />
<br />
qty2 10<br />
prices 15<br />
<br />
qty3 50<br />
prices 10<br />
<br />
qty4 100<br />
prices 8<br />
<br />
qty5 200<br />
prices 6<br />
<br />
qty6 500<br />
prices 4
Now, If I enter qty=5,return prices 20 and 15 (qty 1 to 10)
for qty=75,return prices 10 and 8 (qty 50 to 100)
for qty=250,return prices 6 and 4 (qty 200 to 500)
and so on.....
got it.
Thanks

I think that you should look at your DB design, for two reasons:
1. You are making this very hard to query for yourself.
2. It's not extensible - what happens if your customer wants to add another quantity band - you add another column and update any sql??
I would suggest that you have a table with your ID (I'm guessing that it's a product table) and then another table like this:
ProductID Quantity Price
Where ProductId and Quantity are the combined PK.
So for product 1 you might then have entries in the above table like:
ID Qty Price
1 10 20
1 30 40
1 40 50
And you then want the price for a band, the select statement would be as follows:
SELECT TOP 1 PRICE
FROM ThisTable
WHERE ID = 1
AND Quantity < 15
ORDER BY Quantity DESC
|
|
|
|
|
try something like this
select Price from Tablename
where qty =(select top 1 qty from TableName where qty<=5) or
qty =(select top 1 qty from TableName where qty>5)

hi imran try this

select price from attributes where qty in (select Max(qty) as qty from attributes where qty < EnterValue) Or qty in (select Min(qty) as qty from attributes where qty > EnterValue)

It's not possible to do for normal public website. (All web developers know that due to the security reason, it's not possible to access the client's system from website.)
But if your client added your website in trust websites and you are also using ActiveX or flash then it is possible.
