Web Forms :: Enable And Disable Regular Expression Validation For Textbox
May 7, 2012
I having a two radio button. When the second radio button is enabled, a text box which accept the email id will appear. I am validating the Email using Regular expression validator.
When the second radio button is clicked, and I enter the invalid email id so that it shows me and error. But when I click the first radio button, it is showing the save validation. I need this to not show the validation when the first radio button is clicked and invalid email id is there in the text box.

I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>

I have a regular expression validation set on text box. I have a grid on the same page with edit and delete buttons. In some cases I don't want the regular expression to fire. For example, I have a scenario where the text box will be disabled but I can still enter data in to the grid and modify it, but the regular expression fires when I modify the grid and the changes in the grid are not processed.how can I stop the validation when I am working on grid. I can see a property causes validation for button to stop validation but don't know how can I stop for the grid.

To validate it I use the regular expression .Then I want to edit the record later. I don't want to edit the zip code ,it's bounded from the select but, the update is keeping asking to re-enter the code.I attached the code to that template as well as the select and update statement

I am using regex for server side validations.
I am facing a problem with regex. I want to check for sepecial characters like ><*&()%$@!~+...
I need to filter these special charecters...but the problem is in my 10 textboxes there only 3 are required...
I can submit the form without entering anything...but my regex is not allowing me to submit the form without giving a space from keyboard...
I just want to check for special charecters and empty textbox without giving a spacebar...
I just check these sites(http://regexlib.com/ and http://www.regular-expressions.info/) and read some documentation on regex...its kind of confusing....
Here is my regex for Middlename: ^[a-zA-Z''-'s]|[ ]{1,40}$ its worked but its not correct....then I changed it to ^[a-zA-Z''-'sd*]{1,40}$ this also not taking emptytextbox without giving a space...
My Goal:
In most of the textboxes I need to allow only numbers and - # _ in some textboxes....
For Address: need to allow alphabets and numbers and #-_' "
City: numbers and alphabets no special chars...
Main problem is I can write regex for most of these stuff but need to all textboxes without entering anything (empty textboxes).My work got stoped due to this.

ID="txtACK855Quantity"
runat="server"
Text='<%# Eval("ACK855Quantity") %>'></asp:Textbox>
<asp:RegularExpressionValidator
id="RegularExpressionValidator1"
runat="server"
ErrorMessage="Invalid" ControlToValidate="txtEstimatedDeliveryDate"
ValidationExpression="^d+$"
Display="Dynamic"></asp:RegularExpressionValidator>
But it's not working. I key a 1 in the textbox and I get the "invalid" errormessage. What am I doing wrong?
