How to setup checkbox to this feature?

Answer 1

While I hope you aren’t actually doing this, the following will accomplish it:

protected void chkSex_CheckedChanged(object sender, EventArgs e)
{
    CheckBox chkSex = (CheckBox)sender;
    chkSex.Text = SexString(chkSex.Checked);
}
protected string SexString(bool sex)
{
    return sex ? "Male" : "Female";
}

And the markup:

<asp:UpdatePanel runat="server">
    <ContentTemplate>
        <asp:CheckBox runat="server" 
            Checked='<%# Eval("Sex") %>'
            OnCheckedChanged="chkSex_CheckedChanged" 
            AutoPostBack="true" 
            Text='<%# SexString((bool)Eval("Sex")) %>'/>
    </ContentTemplate>
</asp:UpdatePanel>
