How to keep two buttons for two different functions in an ASP.NET web page?

I want to make a website. Following screenshot are of my Login/Signup link page. When I'm clicking on Login button without giving any data, it is showing me an ALERT. Its OK. But the problem is that, when I'm pressing Register button to go to Signup/Registration page, at that time "Text Boxes" is also showing me this validation. That's why I'm unable to go to Signup/Registration page.
<table id="Table2" runat="server" align="center" style="margin-top:15px; width:72%; height:170px">
<tr style="text-align:center; width:80%; height:8px;">
<td style="font-size:medium; font-family:Courier New; font-weight:bold ;color:#000000; text-align:left ; width:20%; height:8px;">Mobile No</td>
<td style=" width:40%;height:8px"><input type="number" id="mobnum" runat="server" style="width:70%; height:23px" required="required" /></td>
</tr>
<tr style="text-align:center; width:80%; height:8px">
<td style="font-size:medium; font-family:Courier New; font-weight:bold ;color:#000000; text-align:left ; width:30%; height:8px">Password</td>
<td style="width:50%; height:8px"><asp:TextBox id="TextBox8" runat="server" style="width:70%; height:23px;" TextMode="Password" re ></asp:TextBox></td>
</tr>
<tr style="text-align:center; width:80%; height:29px">
<td style="width:30%; height:29px"></td>
<td style="width:50%; height:29px"><asp:Button ID="Button2" runat="server" ValidationGroup="IsValid" height="30px" width="100px" BackColor="#006400" BorderColor="White" BorderStyle="None" ForeColor="White" Text="Login" Font-Bold="true" /></td>
</tr>
</table>
<table id="Table4" runat="server" align="center" style="margin-top:15px; width: 72%; height:170px">
<tr style="text-align:center; width:100%; height:8px;">
<td style="width:100%; height:10px; text-align:center"><asp:Button ID="Button1" runat="server" PostBackUrl="~/Signup.aspx" CausesValidation="false" height="30px" width="100px" BackColor="#006400" BorderColor="White" BorderStyle="None" ForeColor="White" Text="Register" Font-Bold="true" OnClick="Button1_Click" /></td>
</tr>
<tr style="text-align:center; width:80%; height:22px;">
<td style="width:100%; height:22px"></td>
</tr>
</table>

You need to group those validations per page (or) based on different actions. In essence you should look for Specifying Validation Groups

There are two ways you can handle this situation;
1. In regester/signup button set CauseValidation to false.
Set ValidationGroup property of Login button and give same ValidationGroup name to all validators.

Just add the attribute CausesValidation="false" to your Register button.
Like this
<asp:Button runat="server" OnClick="OnClick" CausesValidation="false"/>
That will skip any validation on your page and allow you to go to your registration page.

</tr>
<tr id="Tr2" runat="server">

</LayoutTemplate>
</asp:ListView>
this is code behind...
dataSource.ConnectionString = connetionString;
dataSource.SelectCommand = "SELECT * FROM tbl_WebMenu where MenuID like'3_';";
mylistView.DataSource = dataSource;
mylistView.DataBind();
thanks in advance.

Eval is used to bind to an UI control that is supposedly read only. it can be used to set any type of property of control.
The complete syntax is "Databinder.Eval", it has to be used in conjunction with databind.
Look at this example.
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="lblRead" runat="server" Text='<%# Eval("FieldName") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
you can even set a property of control using eval. it provides flexibility.
But there is a downside of eval as it uses reflection to evaluate the expression.

When I am applying the column ID into targetconrtolID of Hovermenuextender its not working and error coming is
The TargetControlID of 'HoverMenuExtender2' is not valid. A control with ID 'cable' could not be found.
I need to display my sub menu on the column ending
the code written is here
<cc1:HoverMenuExtender ID="HoverMenuExtender2" runat="server" PopupControlID="ProjectMenu" TargetControlID="cable" PopupPosition="Bottom" >
</cc1:HoverMenuExtender>
<td align="center" style="border: medium solid White" class="style5" id="cable">
<asp:LinkButton ID="lblmenudashboard" runat="server" Font-Bold="False" Font-Underline="False"
ForeColor="white" OnClick="lblmenudashboard_Click">Dashboard</asp:LinkButton>
</td>
<asp:Panel ID="ProjectMenu" runat="server" Visible="true" Width="210px">
<table cellpadding="0" cellspacing="0" class="style8" align="center">

<asp:LinkButton ID="lblsubMenu_Udaan" runat="server" Font-Bold="False" Font-Underline="False"
ForeColor="white"> Project1</asp:LinkButton>
</td>
</tr>
</table>
</asp:Panel>
I have applied the scriptManager. Also Let me know how can I select that hovermenu so that I can open tab from their itself.

ValidatorCalloutExtender and ModalPopupExtender Issues on MasterPage

I have just created a website with a MasterPage. I have two conditions that will illustrate my problem:
Condition 1:
I have added a ModalPopupExtender on website.master. It has three fields and each field has a RequiredFieldValidator and a ValidatorCalloutExtender.
Condition 2:
I have a few different pages where you can click on a registration link. When you click the registration link, a registration form will appear. This form also has RequiredFieldValidators and ValidatorCalloutExtenders for each field.
Problem:
If I open a registration form and want to place my feedback, I click on the feedback button. The feedback modal popup displays. If I click on the submit button without filling the feedback form, it should give me the error in ValidatorCalloutExtender format on the ModalPopupExtender panel. However, it doesnt show me any error but the ValidatorCalloutExtender does show on the registation form along with respective validation.
<cc1:ModalPopupExtender CancelControlID="lnk_cancel" ID="popup_change_password" BackgroundCssClass="modalBackground"
runat="server" TargetControlID="ImageButton1" PopupControlID="panel_change_password">
</cc1:ModalPopupExtender>
<asp:Panel ID="panel_change_password" runat="server" Style="display: none; height: 400px;

Put the above code in an UpdatePanel with UpdateMode="Conditional" and ChildrenAsTriggers="False".
So it will look something like :
<asp:UpdatePanel ID="sbsModalExtenderUpdatePanel" runat="server" UpdateMode="Conditional"
Visible="False" ChildrenAsTriggers="False">
<ContentTemplate>
<asp:Panel ID="StepByStepBookingPanel" runat="server" Enabled="false" EnableViewState="false"
Style="display: block" CssClass="mediumModalPopup" ScrollBars="Auto" Width="800px"
Height="300px" ViewStateMode="Enabled">
<div id="clientCoordDiv" runat="server">
<table id="StepByStepTable" runat="server">
etc...
</table>
</div>
</asp:Panel>
<ajax:ModalPopupExtender ID="mpeStepByStepBooking" runat="server" BackgroundCssClass="modalBackground"
PopupControlID="StepByStepBookingPanel" CancelControlID="BtnCancel" OnCancelScript="ClearStepByStepPopup"
TargetControlID="hdnStepByStepButton" DropShadow="true" BehaviorID="modalwithinput" />
<asp:CompareValidator ID="ClientCoordinatorCompareValidator" runat="server" ErrorMessage="Please select a Client Coordinator"
ControlToValidate="ddlClientCoordinator" Display="None" Operator="NotEqual" SetFocusOnError="True"
Type="Integer" ValueToCompare="0" ValidationGroup="SelectionRequired">
</asp:CompareValidator>
<asp:CompareValidator ID="CVOCoordinatorCompareValidator" runat="server" ErrorMessage="Please select a CVO Coordinator"
ControlToValidate="ddlCVOCoordinator" Display="None" Operator="NotEqual" ValueToCompare="0"
Type="Integer" SetFocusOnError="True" ValidationGroup="SelectionRequired">
</asp:CompareValidator>
<ajax:ValidatorCalloutExtender ID="CompareClientCoordinatorExt" runat="server" Enabled="True"
TargetControlID="ClientCoordinatorCompareValidator" BehaviorID="ClientValidatorExt">
</ajax:ValidatorCalloutExtender>
<ajax:ValidatorCalloutExtender ID="CVOCoordinatorCompareValidatorExt" BehaviorID="CVOValidatorExt"
runat="server" Enabled="True" TargetControlID="CVOCoordinatorCompareValidator">
</ajax:ValidatorCalloutExtender>
</ContentTemplate>
</asp:UpdatePanel>
This will keep the dialog up while you validate it. Unfortunately, I do not have the full solution since my validator messages are not displaying. So far, from what I am getting on the Net it is a problem with the Ajax library. Ugly!
Oh well, hope this helps someone...

only one thing i just need in web.config and make it working
<httpRuntime executionTimeout="90" maxRequestLength="2000000" useFullyQualifiedRedirectUrl="false" requestLengthDiskThreshold="8192"/>
Point up my answer if you got your solution.

You can set Triggers on update panel. After that you can get file at server side.
<Triggers>
<ajax:PostBackTrigger ControlID="btnAddNews" />
</Triggers>
Hope it will help.
