Gridview update not working for AccessDataSource

[Morris Neuman]

Hi,

I am trying to update a row in a GridView that uses a table with a join to
another table and using hidden column info for a parameter. I have set the
DataKeyNames for the GridView.

The page is working when I bind the GridView (GridView1) to my SqlDataDource
(SqlDataSource1), however it does not work when the GridView is bound to my
AccessDataSource (AccessDataSource1).

The page accesses 2 tables as follows:
1) Attendant which has AttendantID Text PK, TimeOfDay Int PK, Extension to
Dial Text.
2) AttTimeOfDayXref which has TimeOfDatNumber Int PK, TimeOfDayDescription
Text.
There is an Inner Join between the tables on the TimeOfDay and
TimeOfDayNumber fields.

My GridView is on the Content Page of a Master page. The GridView shows
fields from both tables

The source code below is set-up where DataSourceID="AccessDataSource1". You
can change to point to SqlDataSource to see it working.

Any help would be very much appreciated.

Hi Morris,

From your description the AccessDataSource doesn't work while the
SqlDataSource does, right?

Please pay attention to this line:
<asp:AccessDataSource ID="AccessDataSource1" runat="server"
DataFile="<%$ ConnectionStrings:CALLMasterMDB %>"

From above code I guess you specify the connection string to the DataFile
property of the AccessDataSource, correct? Actually this property is used
to specify the location of the data base file instead of the connection
string:
http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.accessdata
source.datafile.aspx

If my guess is correct please change the DataFile to point to the location
of the data base file. If it still doesn't work please send me a demo
project that can reproduce this problem. My email is
(e-mail address removed). Looking forward to your reply.

You may note some changes in my code comparing to yours. First one is the
DataKeyNames. I think we only need two.The second is, I used
Eval("TimeOfDayDescription") instead of Bind.It's a good practice to use
Bind when it's really need.The third one is to change the UpdateCommand.
The last one is removing some redundant parameters in the UpdateParameters.

BTW,please have a look at this tutorial about Styles, Themes, and Skins. It
will help to write neat aspx code and save your time:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/themes/default.aspx

Please have a try and let me know if it works.

|
| Hi,
|
| I am trying to update a row in a GridView that uses a table with a join
to
| another table and using hidden column info for a parameter. I have set
the
| DataKeyNames for the GridView.
|
| The page is working when I bind the GridView (GridView1) to my
SqlDataDource
| (SqlDataSource1), however it does not work when the GridView is bound to
my
| AccessDataSource (AccessDataSource1).
|
| The page accesses 2 tables as follows:
| 1) Attendant which has AttendantID Text PK, TimeOfDay Int PK, Extension
to
| Dial Text.
| 2) AttTimeOfDayXref which has TimeOfDatNumber Int PK,
TimeOfDayDescription
| Text.
| There is an Inner Join between the tables on the TimeOfDay and
| TimeOfDayNumber fields.
|
| My GridView is on the Content Page of a Master page. The GridView shows
| fields from both tables
|
| The source code below is set-up where DataSourceID="AccessDataSource1".
You
| can change to point to SqlDataSource to see it working.
|
| Any help would be very much appreciated.

Thank you very much. Your solution solved the problem.

Just for the future so I can learn, was it the change from Bind to Eval that
solved it and if so why?

Also if I have a field declared in the DataKeyNames then I do not need to
declare as a parameter in the db query?

Once again I appreciate your help.

 

[Allen Chen [MSFT]]

Hi Morris,

Glad to know you've solved this issue. As to your questions:

Q: Was it the change from Bind to Eval that solved it and if so why?

A: No. I think I need to clarify when to use Bind. Generally speaking Bind
is used when we need to provide a parameter in updating or inserting. In
your case, the TimeOfDayDescription field is not needed for the
UpdateCommand. So it's a good practice to use Eval. Otherwise a redundant
parameter will be provided, which can cause some problems if we write code
carelessly.

Q: If I have a field declared in the DataKeyNames then I do not need to
declare as a parameter in the db query?

A: Yes. The field declared in the DataKeyNames will be assigned to the
parameters automatically. Another note is, the fields in the DataKeyNames
are readonly. They cannot be updated.

Please feel free to ask if you need further assistance.

Allen Chen

| Thank you very much. Your solution solved the problem.
|
| Just for the future so I can learn, was it the change from Bind to Eval
that
| solved it and if so why?
|
| Also if I have a field declared in the DataKeyNames then I do not need to
| declare as a parameter in the db query?
|
| Once again I appreciate your help.

join

set

to

| > | AccessDataSource (AccessDataSource1).
| > |
| > | The page accesses 2 tables as follows:
| > | 1) Attendant which has AttendantID Text PK, TimeOfDay Int PK,
Extension
| > to
| > | Dial Text.
| > | 2) AttTimeOfDayXref which has TimeOfDatNumber Int PK,
| > TimeOfDayDescription
| > | Text.
| > | There is an Inner Join between the tables on the TimeOfDay and
| > | TimeOfDayNumber fields.
| > |
| > | My GridView is on the Content Page of a Master page. The GridView
shows

| > |
| > | The source code below is set-up where
DataSourceID="AccessDataSource1".
| > You
