Hi, i would like to use FilterTextBoxExtender to have a control on a textbox where user can only key in "+" and integer to the textbox.
For example : +60125966874
Does ayone has idea on this? I currently only know how to set it either be numeric or aphabeths only....
Re: FilterTextBoxExtendet to support specific string
My question would be if every response will require a + sybol... if so then there isn't a need to input it, you can prepend the symbol to the number post submittal. If that isn't the case you can always add a radio button with the value of the symbol before your form field and then concatenate the two form values for the final you are looking for.
