problem with switch case statement

Hey,

I have been working on a project where I have to disable certain menu items according to user level in the load event. For that first I retrieve database info as form name (BA,BB etc.) and value (true/false) columns to a datagrid. The form name is assigned to variable formName .If value = true the relevant form is enabled.

My problem is after geting the formName the switch statement doesn't get executed. But when string formName = "BA"; is given manually it goes inside the switch. I tried with if statement and got the same problem. Please help me out with this.I tried a lot but coudn't find the error.

Thanks in advance.

for (int i = 0; i < dt.Rows.Count; i++)

{

if (Boolean.Parse(dt.Rows[i][1].ToString()) == true) //if true enable relevant form

{

string formName = dt.Rows[i][0].ToString(); // doesn't work

// string formName = "BA"; works this way

switch (formName) // doesn't go inside the switch

{

case "BA":

BA.Enabled = true;

break;

}

The only conclusion that can be drawn is that formName doesn contain "BA" - perhaps it includes some whitespace as well which would be enough to prevent the code in the switch statement from executing.

To ascertain the true position, I'd do a MessageBox.Show:

string formName = dt.Rows[i][0].ToString(); // doesn't work
MessageBox.Show(string.Format("{0}, length {1}", formName, formName.Length));
// string formName = "BA"; works this way

switch (formName) // doesn't go inside the switch
{
//..
}

If whitespace is the reason for the bug, then apply the Trim() method to formName:

switch (formName.Trim())
{
//..
}
