Which is better for binding data to the Grid & for data access.

I have 2 sample codes I want to share, I just want to know which is better.


Class Module:

Public connClaims = <connection string>

Public Function ExecQuery(ByVal ConnStr As String, ByVal query As String, ByVal tablename As String) As DataTable

Return ExecCommand(ConnStr, query, tablename)

End Function


Dim dtAgent As New DataTable

dtAgent = objLibMain.ExecQuery(class1.connClaims, "Select * from ...", dtAgent.TableName)

GridView1.DataSource = dtAgent



I'll Just use a sqldatasource?

like for example:

Sqldatasource1.selectcommand = "Select * from........."

Wizard DataSource such as SqlDataSource are good but for me,I would prefer using (Option 1 with DataSets/DataReader over Wizard DataSources)- I called it the hard-coded dataset  because I can write my own logic there. SqlDataSource is good and could be preferred if a simple query is to be generated. But it tends to get complicated and confusing when it comes to intertwined queries. SqlDataSource is also hard to maintain in case of huge blocks of code and we have to generate umpteen DataSources for different data controls. Where as in the case of hard-coded sql databind, we can reuse the code without any hiccups changing the basic query here and there according to requirements and It is also a lot easier to maintain it.

 Hi Friend,

     You can bind the grid manually or with sql datasource. As  a programmer we must know what will happen in the code and what time the code will be execute. If you are using sql datasource we need to declare every thing before page execution. If we need to assign at the runtime somany complications will come with the sql datasource. So manually binding the data to the grid is better. If we are not using multiple tables then datatable is better than the dataset.

Bind Data to an Image Control not in a Data Presentation Control
I've been searching for two days but I don't really know what to search for.I'm making a site for a photographer.  The Default.aspx page displays Albums by showing a title, image and description from the database table Albums.

Diff Between Data Reader & Data Set in Webb App / Grid COntrol
I know this subject is probably a little to big for a forum answer but I have been wondering what the difference is between a datareader and a dataset is in terms of a web app? Whether I use a datareader or a dataset to populate a grid with 100 records, the html sent to the browser is almost exactly the same, judging from the browser's source button. I would also think that once the grid is populated by the dataset or datareader object and control exits the function, both the data reader and the data set object would be destroyed, only to be recreated the next time the grid is p...

Data presentation without a data control
The Gridview and Formview controls provide good functionality in some circumstances but are clumsey in others. As a newbie to .NET I was wondering if its appropriate to do databinding with textboxes and other data controls outside of one of the new data controls (formview, gridview, etc). Or is it a new standard to always use one of the new data controls. If the answer is yes, would you still use an SQLDatasource, or would you set up the connection in code? And, how would you deal with the syntax? In the Formview we have: <asp:TextBox ID="fnameTextBox" runat="server" ...
