i have a confirmbuttonextender from ajax and also i have customvalidation control and i want my custom validation to be fired and my custom validation is server side events.
what happening is, when i click on the button, first i get the confirm message and then i get the errors in the page
is that possible that, first it validates the page and if everything is valid in the page then i get the confirm message ?
below is my code:
<ajaxToolkit:ConfirmButtonExtenderTargetControlID="btnSave"ID="ConfirmButtonExtender1"runat="server"></ajaxToolkit:ConfirmButtonExtender>
this.ConfirmButtonExtender1.ConfirmText ="Are you sure you want to save!";
my custom validation control:
<asp:CustomValidatorID="cv_Remarks"runat="server"ControlToValidate="txtRemarks"ErrorMessage="At least 3 characters required!"OnServerValidate="cv_Remarks_ServerValidate"ValidateEmptyText="True"></asp:CustomValidator>
protectedvoid cv_Remarks_ServerValidate(object source,ServerValidateEventArgs args){
if (this.txtRemarks.Text.Length >= 3)
{
args.IsValid =true;
}
else
{
args.IsValid =false;
}
}
i want to use server side control to process other information but i have just give you the simple example to make my point.
thanks

I don't think you should use server side validation in your situation. Here is a sample which use client side validation.
<%@. Page Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> </script><html><head id="Head1" runat="server"> <title>CustomValidator Example</title></head><body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:Label ID="Message" Text="Enter an even number:" Font-Size="10pt" runat="server" AssociatedControlID="Text1" /> <br /> <asp:TextBox ID="Text1" runat="server" /> <br /><%=DateTime.Now.ToString()%> <asp:CustomValidator ID="CustomValidator1" ControlToValidate="Text1" EnableClientScript="true" ClientValidationFunction="ClientValidate" Display="Static" ErrorMessage="Not an even number!" ForeColor="green" Font-Size="10pt" runat="server"/> <ajaxToolkit:ConfirmButtonExtender ID="ConfirmButtonExtender1" runat="server" TargetControlID="Button2" ConfirmText="Are you sure?"> </ajaxToolkit:ConfirmButtonExtender> <div style="display:none"><asp:Button ID="Button2" runat="server" Text="Button"/></div> <br /> <asp:Button ID="Button1" runat="server" Text="Click" OnClientClick="submitForm()" /> </div> </form></body></html><script type="text/javascript" language="javascript"> var flag =false; function submitForm(){ flag = true; } function ClientValidate(sender, clientside_arguments) { if (clientside_arguments.Value % 2 == 0 ) { clientside_arguments.IsValid=true; if(flag){ flag = false; $get("<%=Button2.ClientID%>").click(); } } else {clientside_arguments.IsValid=false}; }</script>I hope this help.
Best regards,

Jonathan,
there is a big reason why i'm using the server_side validation.
thanks
Hi Nisarkhan,
Ok, here is a sample which use server side validation. It is a little urgly, but get what you want. We suggest that you should wholly copy it to your project and have a test. This sample shows if the input is a plural, it will show your the confirm dialogue when the Button is clicked.
<%@. Page Language="C#" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"> void ServerValidation(object source, ServerValidateEventArgs args) { try { // Test whether the value entered into the text box is even. int i = int.Parse(args.Value); args.IsValid = ((i % 2) == 0); if (i % 2 == 0) // Actually, it postback twice, but the we should only show confirm once. { if(HiddenField1.Value == "true") HiddenField1.Value = "false"; else HiddenField1.Value = "true"; } } catch (Exception ex) { args.IsValid = false; } }</script><html><head id="Head1" runat="server"> <title>CustomValidator Example</title></head><body> <form id="form1" runat="server"> <div> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:Label ID="Message" Text="Enter an even number:" Font-Size="10pt" runat="server" AssociatedControlID="Text1" /> <br /> <asp:TextBox ID="Text1" runat="server" /> <br /><%=DateTime.Now.ToString()%> <asp:CustomValidator ID="CustomValidator1" ControlToValidate="Text1" OnServerValidate="ServerValidation" Display="Static" ErrorMessage="Not an even number!" ForeColor="green" Font-Size="10pt" runat="server"/> <ajaxToolkit:ConfirmButtonExtender ID="ConfirmButtonExtender1" runat="server" TargetControlID="Button2" ConfirmText="Are you sure?"> </ajaxToolkit:ConfirmButtonExtender> <div style="display:none"><asp:Button ID="Button2" runat="server" Text="Button" /></div> <asp:HiddenField ID="HiddenField1" runat="server" Value="false" /> <br /> <asp:Button ID="ValidateBtn" runat="server" Text="Click" /> </div> <script type="text/javascript" language="javascript"> function pageLoad(){ if($get("<%=HiddenField1.ClientID%>").value=="true") $get("<%=Button2.ClientID%>").click(); } </script> </form></body></html>Best regards,
Jonathan
Its not working the way it should work... some times i don't get the error and some times i get the confirmation dialog box and sometimes not...
i think i can deal with confirmation first and then validation.
but your sample its not stable if you run the above sample you know what i mean by that.
thanks for your help.
Hi Nisarkhan,
i think i can deal with confirmation first and then validation.
Yes , I agreee.
but your sample its not stable if you run the above sample you know what i mean by that.
Please be sure, my sample shows the confirm dialogue just when a plural is entered If it's empty, no confirm dialogue when you click the Button. For us, we usually provide a way that our community members can follow or reference instead of a perfect sample. A perfect sample should based on its usage. So thanks for understanding.
Best regards,
Jonathan
