Refresh partial page on user control text change event

I have one Usercontrol Textbox with some radio buttons.
I want to refresh some of these buttons when I change the usercontrol textbox value.
In short, when I select Specific button it displays RM row & for All radio button selection it hides RM row. After selecting RM & checking Client radio button, it again displays two radio button below. By checking any of radio it displays the grid data below. For Prospect & Closed button it displays grid data below after checking it.
For all radio all the functionality is same except RM selection.
My all functionality is working as expected just need to add one more addition in it.
Now I want to refresh 5 radio buttons(Client, Prospect, Closed, Client, Family) which are below RM user control screen when I change the RM name from usercontrol textbox.
I tried using update panel but it couldn't work as it got mess for me so reverted all that changes. My current working code is as below:
<script type="text/javascript">

Why no CSS showing after printing using Window.Print()?

I want to print one particular div in my page. And to do so I am using the following code:

WindowObject.document.writeln('<!DOCTYPE html>');
WindowObject.document.writeln('<html><head>');
WindowObject.document.writeln('<style type="text/css" media="all">.labelalign {float: right !important;}.design {font-size: 16px;}.design1 {font-size: 15px;}.td {background-color: #A4A4A4;}</style>');
WindowObject.document.writeln('</head><body>');
WindowObject.document.writeln(DocumentContainer.innerHTML);
WindowObject.document.writeln('</body></html>');
WindowObject.document.close();
WindowObject.focus();
WindowObject.print();
WindowObject.close();

I am getting like this into the printing window:
But this is my original design:
But when it prints it is not taking any CSS style specified for each label or TD. Please help me on this. Thanks.

Try creating the sytle element using document.createElement('style').
function printDiv(divID) {
var DocumentContainer = document.getElementById(divID);
var WindowObject = window.open('', 'PrintWindow', 'width=750,height=650,top=50,left=50,toolbars=no,scrollbars=yes,status=no,resizable=yes');
var style = document.createElement('style');
var css = '.labelalign {float: right !important;}.design {font-size: 16px;}.design1 {font-size: 15px;}.td {background-color: #A4A4A4;}';
WindowObject.document.writeln('<!DOCTYPE html>');
WindowObject.document.writeln('<html><head>');
WindowObject.document.writeln('</head><body>');
WindowObject.document.writeln(DocumentContainer.innerHTML);
WindowObject.document.writeln('</body></html>');
style.type = 'text/css';
if (style.styleSheet){
style.styleSheet.cssText = css;
} else {
style.appendChild(document.createTextNode(css));
}
head = WindowObject.document.head || WindowObject.document.getElementsByTagName('head')[0];
head.appendChild(style);
WindowObject.document.close();
WindowObject.focus();
WindowObject.print();
WindowObject.close();
}

Ok , here is your working code , i have added test table with small test style , updated to your html
<Button ID="Btnpdfprint" runat="server" Text="Print to PDF" OnClick="printDiv('mydiv')" />click</button>
<script type="text/javascript">
function printDiv(divID) {
var DocumentContainer = document.getElementById(divID);
var WindowObject = window.open('', 'PrintWindow', 'width=750,height=650,top=50,left=50,toolbars=no,scrollbars=yes,status=no,resizable=yes');
WindowObject.document.writeln('<!DOCTYPE html>');
WindowObject.document.writeln('<html><head>');
WindowObject.document.writeln('<style type="text/css" media="all">#mydiv{color:red;font-size:30px; background-color: #1a4567 !important;-webkit-print-color-adjust: exact; }</style>');
WindowObject.document.writeln('</head><body>');
WindowObject.document.writeln('<div id="mydiv"><table><tr><td>table for test</td></tr></table></div>');
WindowObject.document.writeln('</body></html>');
WindowObject.document.close();
WindowObject.focus();
WindowObject.print();
WindowObject.close();
}
</script>
notes : i just replaced this line WindowObject.document.writeln(DocumentContainer.innerHTML);
with the html directly
and i have added small css attribute to the style
-webkit-print-color-adjust: exact;

how to count of datalist item (which is an image)

i want to count items image (ImageUploaded) in Datalist in javascript how can i do that.
<asp:DataList ID="DataListUploadedPhotos" ClientIDMode="Static" runat="server" RepeatDirection="Horizontal" RepeatColumns="3" CellPadding="10" CellSpacing="10" OnItemDataBound="DataListUploadedPhotos_ItemDataBound" ItemStyle-VerticalAlign="Top">
<ItemTemplate>
<table border="0" cellpadding="2" cellspacing="0" align="left" width="100%">
<tr> <td align="left" style="width:200px; height:30px">
<b>
<asp:Label ID="LabelImageTitle" runat="server" Text='<%#Eval("title")%>' Height="10px"></asp:Label>
</b> </td> <td align="right"> </td> </tr> <tr> <td align="center" colspan="2" style="background-color: #eeeeee; width: 260px; height: 260px" valign="middle">
<asp:Image ID="ImageUploaded" runat="server" ImageUrl='<%#"../upload/photos/LargeThumbs/"+Eval("fileName")%>'
AlternateText='<%#Eval("title")%>' ClientIDMode="Static" Style="border: 5px solid #eeeeee;" onclick='<%# "return ImageSelected(this.id, " + Eval("photoId") +",\"ContentPlaceHolder1_txtIds\");"%>' /></td>
</tr>
<tr>
<td>
<a href='<%#"../upload/photos/PopUpThumbs/"+Eval("fileName")%>'>
<asp:ImageButton ID="ImageButtonResultClose" runat="server" ImageUrl="~/images/enlarge.png" /> </a>
<asp:Label ID="LabelPhotoid" runat="server" Text='<%#Eval("photoId")%>'></asp:Label>
</td>
<td>
<asp:ImageButton ID="details" runat="server" ImageUrl="~/images/details.png" OnClick="details_Click"
CommandArgument='<%#Eval("photoId")%>'/>
</td></tr>
<tr>
<td>
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>

you need to count the items in the folder where you are uploading the image
Something like this
string mydir = #"C:\images\";
string[] files;
int numberofFiles;
files = Directory.GetFiles(mydir);
numberofFiles = files.Length;
string nextFileName = (numberofFiles + 1).ToString() + ".jpg";
Let me know if that helps

Give your image a class for example ClassName = "imgUploaded". if you use jQuery then the count of the img will be $(".imgUploaded").length

Open a ModalPopupExtender on an UpdatePanel using javascript

I'm trying to open a ModalPopup with JavaScript, and i've searched here on stackoverflow and the general advice seems be to use something like this:
$('#inputAdd').live("click", function () {
$('#addRow').show();
$find('<%=mpeIndications.BehaviorID %>').show();
});
Where #inputAdd is an html input image that i have in the ModalPopup, its objective is to show a row (#addRow) where a TextBox is shown. However, when i click on the #inputAdd button, it show the row, but then the ModalPopup hide, I think the reason maybe because there is an UpdatePanel that include the ModalPopup, I am right? In that case which may be a solution? I've putted some of the code I've in the .ascx. Thanks.

Then try this approach:
Add a hidden link for ModalPopup Extender to attach to(which will NEVER be used)
<a href="#" style="display:none;visibility:hidden;"
onclick="return false" ID="dummyLink" runat="server">dummy</a>
Add the ID of the hidden link to the ModalPopupExtender
<act:ModalPopupExtender ID="mpeIndications" runat="server" PopupControlID="pnlIndications"
BackgroundCssClass="modalBackground"
TargetControlID="dummyLink"
CancelControlID="imbCloseIndications"
BehaviorID="mpeIndications">
Showing the modal popup
$find('MyMPE').show();
