How to validate a textbox for the spaces

[compu66]

Hi all,

I have textbox,if the user enters spaces it should throw an error.
I think it can only be possible by custom validator.Or is there any thing other way than this.

Thanks.

If Trim(TextBoxName.Text) == "" then
throw ex;

The regualar i am using is [a-z A-Z -]{1,20},this is working good but dont handle spaces.

You can use a RegularExpressionValidator, and/or you could check it yourself by using the IndexOf method on the Text property.

Hi,

I tried using Custom Validator handling Client and server side code.

function tbSpaces(source,args){
if(trim(txtFirstname)==""){
args.IsValid=false;}
else{
args.IsValid=true;}

}


Protected Sub tbSpaces(ByVal source As System.Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs)
args.IsValid = True
If Trim(txtFirstName.Text) = "" Then
args.IsValid = False
Else
args.IsValid = True


End If
End Sub


But not reached the solution.

Thanks for the help in advance.
