Hi,
Try this
private bool txtNumericStringIsValid()
{
if (txtpin.Text == string.Empty)
{
return true;
}
char[] testArr = txtpin.Text.ToCharArray();
bool testBool = false;
for (int i = 0; i < testArr.Length; i++)
{
if (!char.IsNumber(testArr[i]))
{
testBool = true;
}
}
return testBool;
}
Thanks & Regards,
Deepika

In the keypress event of textbox write below code..
If (char.IsDigit()) then
e.handled=true
else
e.handled=false
End if
The keypress event will be be fired every time u press any of the key
and TextBox will accept only numbers u have entered.

if (!Char.IsControl(e.KeyChar))
{
e.Handled = !Char.IsDigit(e.KeyChar);
}

Hello friend,
Here is a solution i am writing to you.
The code restricts as user to enter any letter in the textbox,i.e. only digits can be entered by this code.
Here is the solution ---------------
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
If e.KeyChar.IsDigit(e.KeyChar) = False And Asc(e.KeyChar) <> 8 Then
If Asc(e.KeyChar) = 13 Then
MsgBox("Please focus to next control.")
Exit Sub
End If
e.Handled = True
MsgBox("Please Enter only digits")
End If
End Sub
---------
Enjoy programming.
AMARJIT SINGH.

Hello friend,
Use Ajax FilteredTextBoxExtender to do this,
<ajaxToolkit:FilteredTextBoxExtender id="FilteredTextBoxExtender2" runat="server" TargetControlID="txtCCNo" FilterType="Numbers"></ajaxToolkit:FilteredTextBoxExtender>
(FilterType="Numbers") means that textbox only allows integer values..
