DataSource Controls :: Having To Detach SQL Database After Changing And SQLdatasource In Design View?
May 14, 2010
everytime I modify an SQLdatasource using VS wizards, I have to dettach the mdf in VS's server exporer, then hit refresh in the browser, then get the applicaiton is offline error message please remove some pia file, but i usually just count to 12 and then hit refresh again and the page renders properlyhad scoured the forum on more than one ocasstiion, think it has something to do with the Admin rights within SQL, Ive tried the SQL server surface configuration tool, and add administrator stuff, but not sure if i should add (user to provision) something like the asp.net thing, or network services or ??also cant figure out where to view which administrators are actually on SQL server,

Not sure if this is for SQL or .net! I have 3 tables which looks like
table1
ID Name
1 Jon
and
table2
ID Number Job
1 1 IT
2 1 Web
3 1 Admin
table1
ID ContractType
1 Temp
1 Perm
An inner join makes one table with 3 rows (I excluding the ID from table 2 for the join) which is saved as a view
viewTable
ID Name Number Job ContractType
1 Jon 1 IT Temp
2 Jon 1 Web Temp
3 Jon 1 Admin Temp
4 Jon 1 IT Perm
5 Jon 1 Web Perm
6 Jon 1 Admin Perm
I want to display these results on a web page via the grid view. However, I don't want to show the user 6 times! I want to show the user name once, the contract type once and each Job! What is the best way to do this? Is there a fault with the database design already? I assume the easiest answer is to not join them in a view but query each section 3 times from the website but I'd rather 1 connection only!

In an asp.net 3.5 web app, I have a page with the following markup/code (this is the brief version, but I believe I got all the relevant info).
[Code]....
The form contains 2 different record types, accessed using the paging controls, depending on the ParentSR field; a parent SR will be something like '1234' while its sub-record will be something like '1234.1'. There are only a few differences in the fields used between the 2 different record types and that is why they are stored in the same table. However, the activity depends on the record type. When browsing from the parent record to the sub-record, the itemtemplate loads fine (notice in the formview's datasource
query, that the sractivity_id field is being pulled along with the subquery value). But when going to edit the record, the page throws an error:
System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.ArgumentOutOfRangeException: 'ddlActivity' has a SelectedValue which is invalid because it does not exist in the list of items.
If i click 'back' and retry, it may take 3 attempts, but then the edittemplate will load just fine. I should also point out that this error does not always occur. I've been trying to figure this out for a couple months and it is driving me nuts, mainly due to the fact that I can't reproduce the error in development--it seems to only occurr in production. Anyone with any thoughts on what is going on?

I am building a page that displays a product's details, with the information being called from an MSSQL database.I would like to be able to have a variable number of features listed for each product, so for example, Product A has a list of 3 features, Product B has a list of 7 features, Product C has 2 features listed etc.I would like to avoid having a lot of NULLS in my database, and would prefer not to restrict the number of possible features listed.Is there a common way to tackle this problem? Is it simply a case of setting up a table just to store features?

I have this sqldatasource:

FROM Items WITH (NOLOCK)

When I call select in codebehind, after 30sec it throws timeout expired SqlException:
[Code]....
again , this select took up to 3 sec to be executed. In application I tried to use SqlConnection and SqlTableAdapter instead of SqlDataSource, with the same query, and again it took up to 3 sec.
If I choose tighter interval (e.g '2011-01-20 00:00:00' - '2011-01-21 00:00:00') , there is no timeout exception, so I know that sqldatasource select is executed correctly. So the conclusion is that sql server is not using index while executing query sent from sqldatasource, but is using index whenever else. I have also checked the index statistics on sql server and it is like that. In profiler i can see slight difference between this two cases. As for SqlDataSource, in events table, in first column "EventClass" after 30 sec, there is this: "RPC:Completed" and application throws timeout. If i use SqlConnection and SqlTableAdapter then at the same place there is this: "SQL:BatchStarting" and "SQL:BatchCompleted" and application does not throws timeout(the index has been used).
what is so special on SqlDataSource connection, that Sql Server performs differently compared to other types of connections?

I have this working on another project I have but cannot figure out why I can't get it to work on another. I have a dropdownlist box with employee names. When an employee is selected, I display the data (address, phone, email, etc.) in a series of textboxes. User can make changes and then click on an "Update" button where I attempt to update the database with the changes using the sqldatasource. The code works without any errors, but the database does not update.
Here's the sqldatasource code (the code behind follows):

In general terms, which way will require more server processing power and which way will return faster queries... if there is even a difference. The client's database is still on the dev MS SQL server but is essentially but the client has decided they want to collect two more fields of information. Both fields are going to be collection text data and probably varchar(300) will be sufficient for the column data types. Would it ultimately be more efficient to
Add two additional columns in the main table so the data is entered directly into each record, or Add an additional table (or two) with a foriegn key to the primary table that holds the info for each new field The SELECT statement for the main table could be modified to either add the new columns (a.NewColumn1 and a.NewColumn2) or it could contain nested SELECT statements that pull in the data from the other tables. Custom daisy-chained Insert or Update statements would be no problem and a cascade Delete relationship would take care of any deletions. I'm just trying to figure out which would be better from a performance standpoint?

i have two sqldatasource controls. one i use to display data in textbox's ,filter'd by a select parameter in page behind code. Once checked, i want to copy this data to the other datasource ,by selecting checkbox.Then display this data in detailsview control.
At present the two datasource controls declared , render data to the page simultaneously during pageload. I want to first check data in textbox's from first source, before second datasource is rendered to screen. note, both are filtered by a page variable. i wish to leave the textbox datasource control in situ, as other controls and code depend on it.The other detailsview datasource is my problem?

I'm playing around with dependency injection in a web-forms website al a Ninject and whilst I have had no problem at all getting the site running smoothly I've had a pretty big problem when viewing individual pages using design mode.
I wouldn't normally use design mode but dragging and dropping web user controls onto a design space is the easiest way by far to add them to a page.
The set-up is pretty much identical to guidelines here The error on the design page is thus:
The type "page name" requests an injection, but no kernel has been registered for the web application. ensure that your project defines a NinjectHttpApplication.
I'm using Asp.Net 4.0 with Ninject and Ninject.Web 2.2 utilizing property injection

I have a GridView bound to a SqlDataSource with a default SelectCommand defined as such:
<asp:SqlDataSource ID="SqlDataSource1" runat="server" DataSourceMode="DataSet"
ConnectionString="<%$ ConnectionStrings:MyConn %>"
ProviderName="MySql.Data.MySqlClient"
SelectCommand="select * from blah blah" />
There are cases where I have to change this query dynamically at runtime, so I do the following:
SqlDataSource1.SelectCommand = sql; // 'sql' is the new query
GridView1.PageIndex = 0;
GridView1.EditIndex = -1;
GridView1.SelectedIndex = -1;
GridView1.DataBind();
updatePanel.Update();
This works just fine actually, but when I click the pagination controls, the result set defaults back to the SelectCommand defined in the SqlDataSource1.
