How Can I Avoid Lots Of Spaces Being Added To The End When Saving Contents Of A Textbox

Hi
I am using FormView, SQL 2005, VB 2005
When I save the contents of Title and Area entry fields , I have lots of spaces added to the end.
Title and Area are MultiLine Textboxes and database:varchar(100)
I thought I had solved the issue using;
TextBox Title = FormView1.FindControl("TitleTextBox") as TextBox;
TextBox Area = FormView1.FindControl("AreaTextBox") as TextBox;
TitleLenTrim = Title.Text.Trim().ToString();
if (TitleLenTrim.Length > 100)
{
TitleLenTrim = TitleLenTrim.Trim().Substring(0, 99);
}
string AreaLenTrim;
AreaLenTrim = Area.Text.Trim().ToString();
if (AreaLenTrim.Length > 100)
{
AreaLenTrim = AreaLenTrim.Trim().ToString();
}
 
string insertSQL;
insertSQL = "INSERT INTO Issue(";
insertSQL += "ProjectID, TypeofEntryID, PriorityID ,Title, Area)";
insertSQL += "VALUES ( '";
insertSQL += ProjectID.Text.ToString() + "', '";
insertSQL += EntryTypeID.Text.ToString() + "', '";
insertSQL += PriorityID.Text.ToString() + "', '";
insertSQL += TitleLenTrim.Trim().ToString() + "', '";
insertSQL += AreaLenTrim.Trim().ToString() + "', '";

Is there any other way I could remove spaces?
Thanks in advance.
