Can you give the validation condition your using as well as the button click functionality?

Member 10523130 16-Jan-14 10:47am

yes my validation expression is-
^[a-zA-Z\\s]+$
what is meant by button click functionality? I didn't get it

Your expression should not find a match if digits are entered.
Can you post the code for your button click.

I have used asp.net validation control regular expression and i have given above expression. and i have not written any code on button clk for this validation.what shud i do

Have you added the ControlToValidate property to your RegularExpressionValidator?

Edit:
You would have added it already because it cannot be left blank, but have you pointed it to the correct control?

Post your code please!

<asp:RegularExpressionValidator ID="RegularExpressionValidator3" runat="server" ErrorMessage="Invalid Surname" Enabled="True" ControlToValidate="txtsur" ForeColor="Red" ValidationExpression="\b[A-Za-z]+\b" Display="Dynamic" SetFocusOnError="True">

Show the code for SurName textbox

Member 10523130 16-Jan-14 12:22pm

i have not written any code for surname textbox..what shud i write?

I mean the SurName textbox control added to aspx page. In ControlToValidate you have assigned "txtsur", so txtsur is the ID of the SurName textbox right?

Member 10523130 16-Jan-14 12:47pm

yes it is the id of surname textbox

As per your regular expression validation the textbox doesn't accepts digits, if you want to have digits in SurName textbox in the ValidationExpression add 0-9 or \d.

In the code behind on the button click function add a condition
if(Page.IsValid) then only make DB call to insert the text values into database.

Your code should look like this

SignUp.aspx

XML

<asp:TextBox ID="txtSur" runat="server"></asp:TextBox>
    <asp:RegularExpressionValidator ID="RegularExpressionValidator3" runat="server" ErrorMessage="Invalid Surname" Enabled="True" ControlToValidate="txtSur" ForeColor="Red" ValidationExpression="\b[A-Za-z0-9]+\b" Display="Dynamic" SetFocusOnError="True">
    <asp:Button ID="SignUpButton"
        runat="server" Text="Sign Up" onclick="SignUpButton_Click" />

In SignUp.aspx.cs

C#

protected void SignUpButton_Click(object sender, EventArgs e)
        {
            if (Page.IsValid)
            {
                //Make a DB call and insert the text values into the DB
            }
        }
