Clienside validation before server side

由 可紊 提交于 2019-12-13 04:17:20
问题 My issues: 1) Postback always occurs 2) Is that the correct way to see if requiredFieldValidator is valid client side? What I would like: User clicks the visible click button. This invokes isValid(). If page is valid then invoke server side function. If page is invalid do alert. <asp:Button ID="btnSubmit" runat="server" Text="Submit" ToolTip="Submit" CausesValidation="true" CssClass="blueNew buttonNew" OnClientClick="isValid(); return false;" /> <div style="display: none;"> <asp:Button ID=

Client-side JS and ASP.NET Postback

由 瘦欲@ 提交于 2019-12-13 03:30:26
问题 I have some client-side JavaScript that sets form fields. When the page posts back, those fields are reset. Why is this? Aren't the field values captured and put in the ViewState when the postback occurs? EDIT: When I break the debugger on Page_Load(), before any code executes after the postback, the form field values are empty. 回答1: Are the form elements that are being populated from your client-side javascript set as disabled? If so, ASP.NET will ignore the value. For example: <asp:TextBox

问题 I have an ASP.NET TextBox with TextMode = TextBoxMode.MultiLine that is used within an AJAX Update Panel. The .Text value has been pre-set to a value that has multiple lines.
