Hi guys:

I want to assign value to label.text form database
but if the value is null i want to assign specific value to the label.text

in brief code like that:

if (UserProfileInformation.Tables[0].Rows[0].IsNull("UserFirstName"))
        {
            UserFirstNameData.Text = "not found";
        }
        else
        {
            UserFirstNameData.Text = UserProfileInformation.Tables[0].Rows[0]["UserFirstName"].ToString();
        }


that code work good ,
but it somewhat long and i have many labels on the page ,
so i want gentle and simple code if it could possible

thanks........

No too difficult

private static void CheckForNull(object obj, Label label, string text)
{
  string labelText = text;
  if(obj != DbNull.Value)
  {
     labelText = obj.ToString();
  }
 
  label.Text = labelText;  
}
 
CheckForNull(UserProfileInformation.Tables[0].Rows[0]["UserFirstName"],
UserFirstNameData, "not found");
