Web Forms :: DropdownList Not Displaying Spaces In Column?

I have a dropdownlist which is bound to a SQL Server 2008 Table.

My issue is i am having some spaces in one of the columns.

But while binding the datasource to this table the column spaces are truncated .

This is illustrated below

The table name is DataTable

DataValue is the column which I needs to get displayed in the dropdownlist

[code]....

I am not sure where the spaces are gone.

The code snippet I used to bind with data is given below

void bindData()
{
strConn = "Data Source=local;integrated security=true;Initial Catalog=Testing";
mycn = new SqlConnection(strConn);
myda = new SqlDataAdapter("Select * FROM DataTable ", mycn);
ds = new DataSet();
myda.Fill(ds, "Table");
DropDownList1.DataSource = ds.Tables[0];
DropDownList1.DataTextField = ds.Tables[0].Columns["DataValues"].ToString();
DropDownList1.DataValueField = ds.Tables[0].Columns["Id"].ToString();
DropDownList1.DataBind();
}
