C#

protected void Button6_Click(object sender, EventArgs e)
   {
       ddl_title.Items.Add(TextBox1.Text.ToString());
       lblAddedSalutation.Text = "Your new title is now ready to be selected";
   }

I am adding the text to a dropdown in ASP.net page.

It is working fine but I have few text boxes below this button and I have used required field validator for those text boxes.

When the textboxes are empty the page is re-loading and ask me to enter the text boxes but I don't to do the requiredfield validator checking at this stage.

Hi, you can't disable postback, but you can use client side postback, its fast and easy to use with Asp.net ajax extension (in the tool box).

here is a link how to use it:

Solution 2

just add display="dynamic" for the requiredfieldvalidator
like this

XML

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
            ControlToValidate="TextBox1"  Display="Dynamic" SetFocusOnError="true" ErrorMessage="*" ForeColor="Red"></asp:RequiredFieldValidator>
