Implementing two contact forms with validation controls in a single page in ASP.NET?

I'm using two contact forms in the same aspx page, one has 4 textbox controls (name- email- subject- body) and send button control.
The second form has 2 textbox controls and send button, all (except the second textbox of the second form) has validation controls (requiredFieldValidator).
This is the code inside the first button click event:
protected void ButtonSend_Click(object sender, EventArgs e)
{
if(Page.IsValid)
{
LabelIRespond.Visible = true;
.....
}
}
there is no code in the second button click event.
the problem is, when the first form validated successful and the second form not validated, the code inside click event not executed. and the error message of the second form appears. They act like they are one form!
The markup for both forms:
<section id="sendSection">
<div id="contactMe">
<h1>Contact me</h1>
</div>
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">

You need to hook up validation controls with the correct button. Right now, button click in first form is causing validation in first contact form as well as second contact form, which is causing Page.IsValid to be false since second form fields are empty and therefore invalid.
So set the validation group of first contact form different from the second contact form as in code below. Then set the ValidationGroup on corresponding validation controls with the same value.
<asp:Button ID="ButtonSend" runat="server" Text="Send" CssClass="btnSend"
Width="80px" OnClick="ButtonSend_Click" UseSubmitBehavior="False"
Font-Names="Century Gothic" ValidationGroup="FirstGroup"/>
<asp:Button ID="Button1" CssClass="sendCV" runat="server"
Text="Request CV" Font-Names="Century Gothic" OnClick="Button1_Click"
ValidationGroup="SecondGroup"/>
NOTE: Make sure that all validation controls have their ValidationGroup also set to appropriate value after you make above code change.

<asp:UpdatePanel > doesn't work inside a table <tr>?

I have a problem getting an <asp:UpdatePanel..> to work inside a <table>.. <tr> </tr> structure and I don't know why. When the UpdatePanel is commented out everything works fine, but when I un-comment the UpdatePanel the contents of the <tr> </tr> tag doesn't even show up in Visual Studio 2010. This content does display when I run the web page but the UpdatePanel doesn't work. Non of my other web pages in this project have this problem but, then again, I use <div>s instead of <table>s in them.
One other thing. The is in my MasterPage.
Here is my script:
<asp:UpdatePanel ID="W9UpdatePanel" runat="server" UpdateMode="Always">
<ContentTemplate>
<tr>
<td colspan="6">
<div class="branchSetupSectionTitle">W-9 Information:</div>
</td>
</tr>
<tr>
<td colspan="2">
<asp:Button ID="btnDownloadW9Pdf" runat="server"
Text="Download W-9" onclick="btnDownloadW9Pdf_Click" AutoPostBack="True" />
<%--<asp:RegularExpressionValidator ID="RegularExpressionValidator24"
runat="server" ControlToValidate="txtFirstPaymentAmount" Display="Dynamic"
ErrorMessage="The dollar amount you entered is in the wrong format."
ForeColor="Red" ValidationExpression="^\d+(\.\d\d)?$">*</asp:RegularExpressionValidator>--%>
<asp:CheckBox ID="chkW9FormSubmitted" runat="server" AutoPostBack="True"
oncheckedchanged="chkW9FormSubmitted_CheckedChanged"
Text=" I have submitted this W-9 Form" />
</td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</ContentTemplate>
</asp:UpdatePanel>
</tr>
The event fires for both the button and the checkbox but the entire page is refreshed.
Thanks for your help.

UpdatePanel needs to render a div or span in order to function correctly. Since neither of these elements can be rendered between table rows, UpdatePanel does not have a placeholder to render the postback response html, and thus it doesn't work.
A workaround in your case may be to see which part of your page does not need to be inside the update panel and leave it outside. You could leave just the contents of <td colspan="2"> inside the UpdatePanel.

The update panel need to be put outside the table. Look at

Toggle visibility of specific elements in a ListView

I have a list view on a page and am trying emulate the toggling effect of a tree view. When first bound the detail elements (LBL_ActionTitle, LBL_Action, LBL_UrlTitle, LBL_Url) are set to visibility = false. I would like to have the click event of the element (LB_ExpandCollapse) toggle the visibility of detail elements directly related to it. IE not all the elements of that type on the page. I am not sure how to accomplish this, or if it can be done, and was hoping that someone could point me in the right direction. Here is the control for reference.
<div id="logContainer">
<asp:ListView ID=LV_Logs runat="server">
<LayoutTemplate>
<table border="0" cellpadding="0" cellspacing="0" style="width:100%">
<tr>
<td></td>
<td style="width:85%" />
</tr>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</table>
</LayoutTemplate>
<ItemTemplate>
<tr>
<td>
<hr />
<asp:LinkButton ID="LB_ExpandCollapse" runat="server" CausesValidation="false" OnClick="expandCollapse_Click">+</asp:LinkButton>
<asp:Label ID="LBL_MessageType" runat="server" Text='<%# Eval("messageType") %>'></asp:Label>
<hr />
</td>
<td style="text-align: right">
<hr />
<asp:Label ID="LBL_Message" runat="server" Text='<%# Eval("messageTime") %>'></asp:Label>
<hr />
</td>
</tr>
<tr style="text-align: left">
<td style="padding-left: 65px">
<asp:Label ID="LBL_ActionTitle" Visibility="false" runat="server" Text="User Action:"></asp:Label>
</td>
<td style="padding-left: 10px">
<asp:Label ID="LBL_Action" Visibility="false" runat="server" Text='<%# Eval("action") %>'></asp:Label>
</td>
</tr>
<tr style="text-align: left">
<td style="padding-left: 65px">
<asp:Label ID="LBL_UrlTitle" Visibility="false" runat="server" Text="URL:"></asp:Label>
</td>
<td style="padding-left: 10px">
<asp:Label ID="LBL_Url" runat="server" Visibility="false" Text='<%# Eval("url") %>'></asp:Label>
</td>
</tr>
</ItemTemplate>
</asp:ListView>
<asp:DataPager ID="DataPagerProducts" runat="server" PagedControlID="LV_Logs"
PageSize="20" OnPreRender="DataPagerProducts_PreRender">
<Fields>
<asp:NextPreviousPagerField ShowFirstPageButton="True" ShowNextPageButton="False" />
<asp:NumericPagerField />
<asp:NextPreviousPagerField ShowLastPageButton="True" ShowPreviousPageButton="False" />
</Fields>
</asp:DataPager>

I suggest you put the ID of the record as an ID on the TR containing the fields you want toggled. Then in your expandCollapseClick also pass the ID, so that you can set the row's style to display:block. Of course this assumes that all the rows start out at display:none. ie.
<tr id='<%# Eval("recordId") %>' style='display:none'>
and then in Javascript (pseudo-code)
function expandCollapseClick(row)
{
document.getElementById(row).style.display = 'block';
}
Then change your button to execute client-side as in:
<button onclick='expandCollapse(<%# Eval("recordId") %>)'>+</button>
This will call the code to display the row, passing in the id of the correct row. Of course this assumes that the table is fully populated when the page is retrieved and all you want to do is hide/show detail.

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.

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...

can anyone help me out from this problem.

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.
