xpath problem

[vrrruuumm]

help please ...... going nuts over this

My code returns error on the maindatasource call, and I dont seem to see the problem.

public void FormEvents_Loading(object sender, LoadingEventArgs e) {

XPathNavigator myRoot = MainDataSource.CreateNavigator();



ProfileService.UserProfileService profileService = new ProfileService.UserProfileService();

profileService.UseDefaultCredentials = true;



ProfileService.PropertyData[] userProps = null;

try {

// Passing null to this method causes the profile of the current user to be returned.

userProps = profileService.GetUserProfileByName(null);

}

catch { }



if (userProps == null || userProps.Length == 0) {

return;

}

for (int i = 0; i < userProps.Length; i++) {

XPathNavigator node = null;

switch (userProps[i].Name.ToLower()) {

// these property names can be obtained by reviewing the user profile properties in the MOSS SSP.

case "preferredname":

node = myRoot.SelectSingleNode("/my:myFields/my:userName", NamespaceManager);

break;

case "accountname":

node = myRoot.SelectSingleNode("/my:myFields/my:userAccount", NamespaceManager);

break;

case "workemail":

node = myRoot.SelectSingleNode("/my:myFields/my:userEmail", NamespaceManager);

break;

case "workphone":

node = myRoot.SelectSingleNode("/my:myFields/my:userPhone", NamespaceManager);

break;

default:

continue;

}

ProfileService.ValueData[] values = userProps[i].Values;

if (values.Length > 0) {

if (node != null && string.IsNullOrEmpty(node.Value)) {

node.SetValue(values[0].Value.ToString());

}

}

}

}

What is the error you're getting? Have you initialized MainDataSource?
Could you show us the code where you're doing so?
