raise_passwordStrengthCalculating

[SSirica]

I ran across a java script function called raise_passwordStrengthCalculating but I can't find any documentaion on it or how to use it?  See I've figured out a way how to get a value from a database into a password field, but I haven't figured out how to get the password field to calculate the password strength.  And I think that function would do it, but can't quite wrap my head around how to call it.

I guess I didn't get my secret decoder ring along with my subscription.

There has got to be a way manually invoke the password strengthchecking via code?  You guys have such nice tools why do you make them so hard to navigate?

OK I figured out how to invole this.  I'm using Subroutine:

Sub setTelerikValue(oObj As Object, sVal As String)
    Dim sScript As String = "<script language='javascript'>" & _
                            "function f() {$find(""" & oObj.ClientID & """).set_value('" & sVal.Trim & "'); " & _
                            "$find(""" & oObj.ClientID & """).raise_passwordStrengthCalculating();" & _
                            "Sys.Application.remove_load(f);}; " & _
                            "Sys.Application.add_load(f);</script>"
    ClientScript.RegisterStartupScript(Me.GetType(), "setPass", sScript)
End Sub

Now I'm getting an error in my OnClientPasswordStrengthCalculating java function:

function CalculatingStrength(sender, args) {
        //throw new Error;
        document.getElementById("<%=txtPassScore.ClientID%>").value = args.get_strengthScore();
}

args is empty, so it throws an error.  What am I missing?

Hi,

You need to construct the event args that you want to pass to the client event.

var eventArgs = new Telerik.Web.UI.PasswordStrengthCalculatingEventArgs(Value, Score, LabelText);
RadTextBox1.raise_passwordStrengthCalculating(eventArgs);

The Value that you pass in the upper code, will be the same as args.get_strengthScore() will return in your handler later.

And if you actually want to make the input to calculate the score and call the event, you need to use this code:

Telerik.Web.UI.PasswordStrengthChecker.prototype.showStrength(TextBox1, TextBox1._textBoxElement, TextBox1._passwordSettings);

where TextBox1 is the client object of your textbox.

Dude you ROCK!!!  That worked perfectly!!!  I can't thank you enough.  For anyone else interested this is the final working version of the Subroutine: 

Sub setTelerikValue(oObj As Object, sVal As String)
    Dim sScript As String = "<script language='javascript'>" & _
                            "function f() {var Obj = $find(""" & oObj.ClientID & """); " & _
                            "Obj.set_value('" & sVal.Trim & "'); " & _
                            "Telerik.Web.UI.PasswordStrengthChecker.prototype.showStrength(Obj, Obj._textBoxElement, Obj._passwordSettings); " & _
                            "Sys.Application.remove_load(f);}; " & _
                            "Sys.Application.add_load(f);</script>"
    ClientScript.RegisterStartupScript(Me.GetType(), "setPass", sScript)
End Sub

and this is how you'd call it:
            setTelerikValue(txtPassword, "PasswordValueHere")

That will set a password field and force the calculation of the password strength.
