Visual C# Net 2003 , Clear textBox problem

[Lennie]

Hi there,
I am a newbie to using Visual C# Net 2003. I am having problem trying to clear all the textbox using FOREACH command structure. In VB6 there was no problem but in C# I do not know how to write the script. Please help me.

Here is the sample of the VB6 version. My boss wants similar events. Private Function FCleartextBox()
Dim ctl As Object
For Each ctl In Me.Controls
If TypeOf ctl Is TextBox Then
ctl.text = ""
End If
Next
End Function
-----------------------------------
C# version tried by me.
Private void FClearTextBox()
{
control ctl = textbox;
foreach ctl in this.controls
{
if typeof ctl is textbox
{
ctl.text = ""
}
}
}

This is a very un-OOP approach. However, if you insist, you can use the typeid() operator to detect the type of an object or better yet, use the safer dynamic_cast operator to detect whether the object is of the desired type.
In proper C++ programming, you would rarely do such things. Instead, a class hierarchy with overridden virtual functions will do the trick.

Hi Danny,
Thank you for your reply. I did not insist of using the VB6 way of clearing the textbox. As I have mentioned I am new to Visual C# Net 2003. In the OOP approach, could you please share with me sample script.

Hi there,
I have tried out this script and it's working. Would like to share this with all Visual C# Net 2003 Newbies just like me. This script main event is to clear all textbox in a Form.

using System.Text;
using System.Collections;

private void FClearTextBox()
{
    foreach ( Control ctl in this.Controls)
           {
               if (ctl.GetType == typeof (TextBox))
                    {
                         ctl.Text = "";
                    }
           }
}

Good Luck and Enjoy yourself.

Have a Good Day.

Hi Hack,
Nice hearing from you again. It has been quite a while. I have edited the block of script I have posted here to share with other C#Net 2003 Newbie using your suggestion of
I am not sure whether to use it on individual line or from before the Start and at the End of the block of script.

Thanks you for your help.
