we have a AutoGenerateColumns-enabled WmxDataGrid in which we are able to update table rows in a DataBase connected with a SqlDataSource.
Each time we clear a field an empty string is written to the database where we want to write DBNull values.
At the moment we generate the update string via UPDATE... SET.. and the SQL Server function NULLIF(value, '').
Works proper but when I want to add the values to e.NewValues in BeginUpdate event I'm not able to read the values from the auto generated text boxes. How do I do that? Is there an easier way to automatically convert empty strings to NULL values?

I'm having a problem with the results of a Gridview. The SQL statement I use works in SQL Management Studio, but in my .NET app, it only display a few of the results. The part of the SQL that seems to be effecting it is in the where statement I use like:
[Code]....
@Consultant comes from the value of a selected dropdown.

I am using VS 2008.I am building a datatable of records to be inserted into a SQL Server 2005 table.
The program loops through this table and builds a SqlParameter for each DataColumn in the datatable. The SqlParameters are used in the SQL Insert statement.
The field I am having a problem with is of type 'bit' in the database table and has no default value and cannot be nulls. The field is called 'Active' The meaning of this field in the application is Boolean i.e True or False. When inserting the record, I wish to default the field to "False".
When I define the columns in the datatable I am forced to use the following code to build the datatcolumn containing the boolean field i.e. dtcActive.DataType = GetType(Boolean) as there is no GetType(Bit)
Dim dtcActive As New DataColumn("Active")
dtcActive.DataType = GetType(Boolean)
dtcActive.Unique = False
dtcActive.AllowDBNull = False
dtcActive.DefaultValue = False
dtProviderDayDetails.Columns.Add(dtcActive)
However, when I build the SqlParameter I am forced to use this:
If field.ColumnName = "Active" Then
prm.SqlDbType = SqlDbType.Bit
prm.Value = "False"
End If
This is because there is no SqlDbType.Boolean. The problem I have is there is no value I have been able to give the SqlParameter that is accepted by the Insert statement. It complains that the boolean field cannot be null on Insert.

I'm using the asp.net membership on my website. On the User Administration page i've got a GridView to show the details of the users on the site. As a datasource rather than just using the Membership.GetAllUsers function i've got a SQLDataSource as i need to display user information from 3 different tables. I'm trying to add a delete button to the GridView. I'm setting the Membership's UserName as a DataKey and then using the RowDeleting event to call Membership.DeleteUser for the appropriate UserName. This works fine and the user is deleted however i then get an error showing up that "Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified."
I don't want to use the SqlDataSource for deleting as i've already done it using the Membership. How can i stop it from trying to do this? Here is the cut-down that i have if you're interested. The selectcommand in the sqldatasource was auto-generated by it.

i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource();
sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString();
sq.SelectCommandType = SqlDataSourceCommandType.Text;
sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1";
string result = sq.Select(some overload that's stopping me);

I am planning to start learning asp.net mvc. And also I want to learn Microsoft's Data Access application block. But I dont want to waste time in MDAC block if theres a better option to go for, or if MVC provides any good feature than MDAC. As I have heard MVC architecture automatically generates code.

It looks that the old SqlHelper class from the Microsoft Enterprise Library has been mostly replaced by the Database class which is included in the new Enterprise Library version 5.
I have a very simple and trivial example:
using Microsoft.ApplicationBlocks.Data;
private void PopulateCheckBoxGroup()
{
const string strConnTxt = "Server=(local);Database=DataBindTests;Integrated Security=True;";
const string strlSql = "select Technology from PreferredTechnology where ParentId = 1";
CheckBoxList1.DataSource = SqlHelper.ExecuteReader(strConnTxt, CommandType.Text, strlSql);
CheckBoxList1.DataTextField = "Technology";
CheckBoxList1.DataBind();
}

I want to know how I could fix the following. I essentially have two almost identical SQL functions and want to combine them into one. The only difference between the two functions is the SQL Command text that is being used. Here is a brief idea of what I have unsuccessfully tried thus far:
[Code]....
I receive no compilation errors, but the exception is thrown and table is not filled. I have a feeling that I am overlooking something obvious.

No matter what I do I keep getting the error that my input string is not valid and that the system cannot convert a string to a double. I have a table with two fields, both are defined as nvarchar(25). My command text is:INSERT INTO OtherProducts VALUES ('Sample','Test') am using Visual Web Developer. This is as simple as it gets. I have tried parameters as well.
