How I can know my sqldatasourse found any record or not I dont want to use datalist or another data table .and how I can put each feild that sqldatasource found on a string object( ineed just one record that sqldatasource found.)
I need a code that on page load automaticly goto another page
What is the C# code I use to do this?
I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 with SQL Express 2005 with VB as the code behindi have one database and three tables in itfor manipulating each table i am using separate SqlDataSource() is it sufficient to use one SqlDataSource() for manipulating all the three tables ? i am manipulating all the tables in the same page only please help me

View 2 Replies View Relatedhi all,
in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>.
I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular.
thanks in advance,

Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks

When more than one checkbox is ticked, I'm getting the error 'The variable name '@ProgrammeID' has already been declared'. How do I close or reset my Datasource before I try and use it again?

Hi, I want to know when to use an sqlDataSource object because I used to populate for example a listBox control in visual studio net 2003 from AQLK server database by using a connection object, command object, dataAdapter object and a DataSet object. I discovered if I use sqlDataSource object (using visual studio net 2005) ,all I need is to write the connection string and a Select statement as properties for that sqlDataSource, so why to use the above mentioned objects(connection,command,adapter,dataset) while I can access any database in sql server through the use of sqlDataSource?
I appreciate if you can explain to me the difference and when to use an sqlDataSource
thx
How can I update more than one table with one UpdateString in SqlDataSource?
View 5 Replies View RelatedHi,
I have an application w/ n-tier design so I've never used the SqlDataSource up to this point but having to do my own sorting for GridViews is not something I want to keep dealing with. I'd like to take advantage of some of the packaged features too.
My question is: are there any purists out there who opted to use SqlDataSource. If so, what do you think about it? It's nice that SqlDataSource makes things simple but having data classes and dealing w/ exceptions in those classes certainly make an application pretty robust. Should I entertain the idea of using SqlDataSource or stay as a purist and keep doing things the old fashioned way?

Dear Friends in my project , i' ve used two SqlDataSource, one button and one gridview control;
the process that i want to do is when i click the button control ,according the if structure in this button control ; one of the SqlDataSource control assign to the gridview control DataSource property (but i assign the DataSourceID property for the gridview , it runs);
but i couldnt do it, what can i do for it? (my code doesnt give any errors but doesnt do anything too)
my code is here;

Could someone help me with syntax? Everything works until line 23. At that point, I get a NullReferenceException. When I examine the SqlDataSource object, everything inside reads "Object cannot be null" or "The pointer for this method was null." The SQLDataSource looks ok, just before executing line 23.
Does anyone have a complete example of how to do this ADO operation?

Hello,What's the difference between using sqldatasource to get data vis-a-vis ado.net?Both can retrieve datareaders and datasets.Any thoughts? Which one is better?From my experience, code-wise, sqldatasource is muuuuch easier.a s a f. . .

View 2 Replies View RelatedHello guys i am a bit confused, because i cannot do a simple select using the SQLDataSource from ASP.NET 2.0
here is how was doing after droping the SQLDatAdapter using the VS2003
Example
SqlDataAdapter1.SelectCommand="select * from users"
SQLDataAdapter1.Fill(Datasource1,"users")
TextBox1.DataBind()
my question is how to do it in VS2005 since that i dont see theDataAdapter anywhere, do i have to do by hand like declaring everything??
thank you in advance!!
normally after a SqlDataSource is added...
if want to update, i will
sqldatasource.updatecommand = "some command"
sqldatasource.update() *runs the function
similarly can be done for insert and delete
however, if i want to change the select command
sqldatasource.selectcommand = "some command"
how do i get the command to run ?? because
sqldatasource.select("Arguments As System.Web.UI.DataSourceSelectArguments")
what command or argument shd i add in btw the ( )??
I have set up a sqlDataSource that returns one value.

Hello All,
I want to use SQLDataSource as a base of all Gridview in my application. I have read that SQLDataSource support caching.
I want to know as SQLDataSource is a child control of page class. It will get unloaded when page is unloaded. So how caching works. Like I am using SQLDataSource as base of my GridView control. When I perform paging or sorting,In theory It says that It will not hit the Datbase again. It will keep that Data in memory as DataSet, but this will stay alive upto life of page, which starts again and again when a page is requested, So as its child controls.
Can anybody give me more intrinsics on this.
Any Help from Microsoft is appreciated !!!!
Thanks !!
Hello, I'm having a problem with SQLDataSource . I'm running a stored procedure that needs to have a the param "@param1" but I have no idea how to supply it with SQLDataSource. Here is what I have so far:Here is the message I get when I try to view the page:Procedure or Function 'list_sp' expects parameter '@param1',
which was not supplied. Front End: <asp:sqldatasource id="CustomersSource" OnUpdating="CustomersSource_Updating" SelectCommandType="StoredProcedure" connectionstring="<%$ ConnectionStrings:DatabaseTEST%>" runat="server" SelectCommand="list_sp"> <UpdateParameters> <asp:Parameter Name="Param1" Type="String" /> </UpdateParameters> </asp:sqldatasource>Back End: protected void CustomersSource_Updating(object sender, SqlDataSourceCommandEventArgs e) { e.Command.Parameters["@Param1"].Value = BaseUtility.regionString(this.User.Region.ToString()); e.Command.Parameters.Add(e.Command.Parameters["@Param1"].Value); }Needless to say, my solution doesn't work and I really don't know what I'm doing as SQLDataSource is new to me. Does anyone out there know how to supply the param value to my stored procedure? Thank you very much :)
