C# - Read Data From SqlDataReader?
Oct 25, 2010I have a SQL Server 2008 database and I am working on it in the backend. I am working on asp.net/C#
SqlDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
//how do I read strings here????
}
I know that the reader has values. My SQL command is to select just 1 column from a table. The column contains strings ONLY. I want to read the strings (rows) in the reader one by one. How do I do this?

DataSource Controls :: Get ArrayList Value In SqlDataReader

DataSource Controls :: Loading Datatable From SQLDataReader Does Not Call Set Method?
Apr 28, 2010When using the DataTable.Load(SQLDataReader) method, if the datatable is a property of a class, the set method is not called to populate the object. For example...
MySQLDataReader = command.ExecuteReader();
if (MySQLDataReader.HasRows)
myObjDataTable.Load(MySQLDataReader); -- The result of this will be 0 rows returned. The "Set" method of the object is never called.
DataSource Controls :: SqlDataReader And The Invalid Attempt To Call FieldCount Error?
Mar 30, 2010I have several methods where I return a SqlDataReader to populate Gridviews, Listview, etc. I get random "Timeout expired" errors regarding connection pooling, so I decided to add using{} to my methods. The lack of using is a carry over from my more beginner days.Below I included the before and after code. The after code always gives me the "Invalid attempt to call FieldCount when reader is closed" error. I have tried various combination of using{}, but ALL result in the same error.What am I doing wrong? Also, from the code below what is the best way to structure this code to ensure no connection leakage?Before:

Using Statement When Setting Control's Datasource To Sqldatareader
Aug 25, 2010I know it is recommended to use a using statement with a sqldatareader, but I was wondering if it is necessary when you are setting the datasource of a control to a datasource directly. in some places in my code I do this.
using (SqlDataReader reader = getReader())
{
while (reader.Read())
{
// do stuff with data
}
}
when binding to a control I do this.
ddlCustomer.DataSource = getReader(); // get Reader returns a sqldataReader
ddlCustomer.DataBind();
In the second case, do I need to use a using statement. Do i have to first declare an SqlDataReader in a using statement, then set the DataSource to that object. Seems like more clutter in the code, so i was hoping binding to the SqlDataReader disploses of the SqlDataReader.

DataSource Controls :: Data In Sql Read Is Not Getting Refreshed?
Feb 1, 2011I am running the code below to read a sql table and populate the values into a list. This works on the first run through, but after the data has been processed, and the process then re runs, if the sql table has been modified externally, the read of the records does not change. I imagine it is being cached somwhere but as I re dim the dData variable, shouldn't it all be dropped and run afresh?
