text box empty problem

i am using gridview and in Rowupdating event using following code:

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)


objCallerListUserMaster.PhoneOne = (((TextBox)GridView1.Rows[e.RowIndex].FindControl("txtPhoneOne")).Text).ToString();

string FinalPhoneNumber1 = "";

if ((objCallerListUserMaster.PhoneOne != "") || (objCallerListUserMaster.PhoneOne != null))


Do something.




lblValidUpdateNumber.Visible = true;

lblValidUpdateNumber.Text = "Please enter valid phone number or numbers in update. please try again.";


My problem is even textbox is empty and i did not enter any thing, it bypass my condition and execute "Do Something"

objCallerListUserMaster.PhoneOne shows ''''' in it but in visualizer it is empty please help

You have used OR (||) condition, use AND (&&) condition...

well i was using or condition in it just to satisfy that it must not enter into code if it donot have phone number.
i solved my problem by writing following code

  if (!string.IsNullOrEmpty(objCallerListUserMaster.Pho neThree))
