Could you plz explain that using a concrete example? thanks

I m not using Forms at all I wanna go for Session or queryString to do this. Is it appropriate? or am I going to have a hard time going this way?
I m using a Master Page, I m thinking of using QueryString and check it in this master page and see whether the user is logged in or not? the querystring will be encrypted and contain the username, something like this

I got it work, i still have just some minor problems in the execution of the ifs. here are the ifs i ve put in my logic:
protected void SearchButton_Click(object sender, EventArgs e)
{

BLL.EmpLNameValidate bl = new BLL.EmpLNameValidate();

if (!bl.RequiredLname(LNameText.Text))
{
Label1.Text = "Last Name is required!";
lblLnameValid.Visible = true;
EmpDataView.Visible = false;
}
else if(!bl.LenghtValidate(LNameText.Text))
{
Label1.Text = "Please enter at least 2 characters!";
lblLnameValid.Visible = true;
EmpDataView.Visible = false;
}
else if (!CharactersValidate(LNameText.Text))
{
Label1.Text = "Only alphabets are allowed!";
lblLnameValid.Visible = true;
EmpDataView.Visible = false;
}
else if (FNameText.Text.Length > 0 & !bl.LenghtValidate(FNameText.Text))
{
Label2.Text = "Please enter at least 2 characters!";
lblFnameValid.Visible = true;
EmpDataView.Visible = false;
}
else if (FNameText.Text.Length > 0 & !CharactersValidate(FNameText.Text))
{
Label2.Text = "Only alphabets are allowed!";
lblFnameValid.Visible = true;
EmpDataView.Visible = false;
}
else
{
lblLnameValid.Visible = false;
lblFnameValid.Visible = false;
Label1.Text = null;
Label2.Text = null;
BindData();

if (EmpDataView.Rows.Count == 0)
{

NewUserLabel.Visible = true;
NewUserButton.Visible = true;

}
else
{
EmpDataView.Visible = true;
NewUserLabel.Visible = false;
NewUserButton.Visible = false;
}

}
}

where my BLL file (Class) looks like this:

namespace Phonebook.BLL
{
// TODO Validate that the user have entred characters for Last Name field
public class EmpLNameValidate
{

// to validate last name is required
public bool RequiredLname(string txt)
{
if (!string.IsNullOrEmpty(txt))
{
return true;
}
else
{

return false;
}
}

// to validate 2 characters lenght
public bool LenghtValidate(string txt)
{
if (txt.Length < 2)
{
return false;

}
else
{
return true;
}

}
}
}

i run it it's working but still some minor "inpurities" in the ifs.

I've done like you said before but it didn't work, maybe I am missing something or I misplaced the logic behind this.
thnks anyway Wes

Predator008 11-Sep-12 11:32am View

:D yeah I can. I've wrote something like that to check characters entred

public bool validateCharacters(string input, string msg) {

const string regExpr = @"^[a-zA-Z]+$"; //regular expression for valid string

// match input with regular expression

System.Text.RegularExpressions.Match m = System.Text.RegularExpressions.Regex.Match(input, regExpr);

if (m.Success) { msg = null;

return true; } else {

msg= "characters"; return false; }

}and like this to check requiered field:

public bool RequiredLname(string txt, string msg) {

if (string.IsNullOrEmpty(txt)) {

msg = "Last name required"; return false;

} else { msg = null;

return true; } }

But I would like to do is use the IsValid in my main page to check the validation using my customvalidators.

Predator008 11-Sep-12 11:20am View

could you plz translate that to a concrete example? like how I should declare my function in BLL file? what parameters to pass?

Predator008 11-Sep-12 11:16am View

to be clear here is what I want:

I have a search button and a GridViewcontrol, whaen a user clicks the button the validation sould validate that the last name has been filled in, and if so it should contain at least 2 characters, then if the user chooses to include first name, he should also enter 2 characters, but it's not a required field:

protected void SearchButton_Click(object sender, EventArgs e) {

//if validation passesBindData();

if (EmpDataView.Rows.Count == 0) {

NewUserLabel.Visible = true;

NewUserButton.Visible = true; }

else {

EmpDataView.Visible = true;

NewUserLabel.Visible = false;

NewUserButton.Visible = false; }

// else show error messages

suppose I create a function called LNameValidate() in BLL file, now I want to call it form my main page in whcich my customvalidator resides, as you said I should go to the events and on Server Validate cell put the name of that function (BLL.LNameValidate())?

Predator008 11-Sep-12 11:01am View

Hey, the problem is that those functions now exist in my main page code behind, I want to place them in a file named BLL in which there is a Class file. I want to put them in this Class file and call them from there. The logic how to do this is not clear to me, how to handel the ServerValidate and TextChanged events from another location.
