Regular Expression Validator Does Not Validate Empty Textbox?
Jun 30, 2010I would like to validate the textbox for specific text and it must not be blank. But the regular expression validator is not validating if the text box is BLANK. However, it validates if I type something in the text box.
How can I make regular expression to trigger even if the text box is empty?
Should I use Required Validator + Regex Validator at the same time?
<asp:TextBox ID="txtcard" runat="server" MaxLength="16"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator2" runat="server"
ControlToValidate="txtcard" ErrorMessage="Please type credit card no"
ValidationExpression="^d{16}$"></asp:RegularExpressionValidator>

View 3 RepliesWeb Forms :: Java Script - Check If More Than One Checkboxs Checked
Mar 16, 2011I have a web form with a gridview control on it. The GridView has a column of check boxes. Before the web form closes I need to check if more than one check box was checked. If more than one check box was checked, then I need to display a popup message box informing the user that only one check box should be checked? I need to check to see if more than one check box was checked, when a "Submit" button on the form is pressed.
How can this be done using Asp.net/C# and Java Script? I know how to iterate through rows of a Grid control so I can do that in the C# code. But how to keep the web form open before I iterate through the rows, I don't know?
