on using ajax, asp.net button control click event not working

I am using Ajax with asp.net C#. What I am trying to do is, on click of a link, a div should appear. A div contains file upload controls and a button named 'Upload Files'. When upload files button is clicked, it is checking if any of the file upload controls has files. If yes, it uploads files to some directory and updates a label to show how many files are uploaded 0 or more. Here is the screenshot to explain:
Here's the code snippet, I am using Ajax with asp.net C#
<div class="form-group row">
<asp:UpdatePanel runat="server" id="UpdatePanel1" updatemode="Conditional">
<ContentTemplate>
<div class="col-xs-5">
<% if (Session["MemberID"]!= null)
{%>
<asp:LinkButton ID="insertMore" runat="server" OnClick="insertMoreclicked">(Insert More Attachments)</asp:LinkButton>
<%} %>
</div><br />
<div id="moreUploadsDiv" runat="server" visible="false">
<br />
<asp:FileUpload ID="moreUpload1" runat="server" />
<asp:FileUpload ID="moreUpload2" runat="server" />
<asp:FileUpload ID="moreUpload3" runat="server" />
<asp:FileUpload ID="moreUpload4" runat="server" />
<asp:Button ID="uploadMoreFilesBtn" runat="server" Text="Upload" OnClick ="uploadMoreClicked" CausesValidation="false" />
<br />
<asp:Label ID="uploadInfoLbl" runat="server" Text=""></asp:Label>
</ContentTemplate>
</asp:UpdatePanel>
Here's the code behind file event for button:
protected void uploadMoreClicked(object sender, EventArgs e)
{
int countFiles = 0;
if (moreUpload1.HasFile)
{
moreUpload1.PostedFile.SaveAs(Server.MapPath("/Upload/") + moreUpload1.FileName);
string fn2 = moreUpload1.FileName;
bool status2 = blReg.insertFiles(fn2, FileID);
countFiles++;
}
if (moreUpload2.HasFile)
{
moreUpload2.PostedFile.SaveAs(Server.MapPath("/Upload/") + moreUpload2.FileName);
string fn2 = moreUpload2.FileName;
bool status2 = blReg.insertFiles(fn2, FileID);
countFiles++;
}
if (moreUpload3.HasFile)
{
moreUpload3.PostedFile.SaveAs(Server.MapPath("/Upload/") + moreUpload3.FileName);
string fn2 = moreUpload3.FileName;
bool status2 = blReg.insertFiles(fn2, FileID);
countFiles++;
}
if (moreUpload4.HasFile)
{
moreUpload4.PostedFile.SaveAs(Server.MapPath("/Upload/") + moreUpload4.FileName);
string fn2 = moreUpload4.FileName;
bool status2 = blReg.insertFiles(fn2, FileID);
countFiles++;
}
uploadInfoLbl.Text = countFiles + " file(s) uploaded<br/>";
}
But button click event doesn't work. Please suggest me what i am doing wrong. Thanks in Advance!

ERROR :- DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Optiont4'

In .aspx page , I’ve taken Label Control in order to display question form the database,
4 radio buttons in order to display four option related to a particular question, and last but not the least, I’ve used hidden field in which I will store answer of the particular question.
And finally I’ve taken a Button Control, for which I’ve created the onclick event, on which I will perform the operation to generate score.
In .aspx.cs page, on the onclick event of the button, , I’ve fetch the controls form the aspx page using code mentioned below, and further I’ve used if statement in order to see which radio button is active and have store the corresponding value in the varialbe “selans”, using this “selans”, I will compare it with the value of hidden field in order to find whether checked radio button is the correct answer or not, it the answer is correct, i.e value in “selans” matches with the value in hidden field ( the actual answer) and the variable “count” ( initially initialized with value 0) increments accordingly, and all this code is placed in the “for loop” which will execute till the no. of controls in the GridView (you can relate it with the no. of question, as for every record GridView generates new control).
But when I run it I am getting this error :-
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Optiont4'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

You have a typing error in your GridView2 definition.
<asp:RadioButton ID="rad4" runat="server" Text='<%#Eval("Optiont4")%>' GroupName="A" />
should be
<asp:RadioButton ID="rad4" runat="server" Text='<%#Eval("Option4")%>' GroupName="A" />

Deleting images from server

I'm writing a code that selects images in a Listview and delete them from the server. Unfortunately I haven't been able to delete any image and no error during debug. Here is the code:
<asp:ListView ID="ListView2" runat="server" DataKeyNames="ID_BG" DataSourceID="SqlDataSource_BGdelete">
<ItemTemplate>
<label><input id="checkbox1" name="BG_list" type="checkbox" runat="server" value='<%# Eval("BG_fileName") %>'/>
<img alt="" style="width:150px" src="/Members/images/BG/icons/<%# Eval("BG_fileName") %>"></label>
</ItemTemplate>
<LayoutTemplate>
<div id="itemPlaceholderContainer" runat="server" style="">
<span runat="server" id="itemPlaceholder" />
</div>
<div style="">
<asp:Button class="btn btn-default" ID="DeleteBackground" runat="server" Text="Delete" OnClick="DeleteBackground_click" />
</div>
</LayoutTemplate>
.....
CODE BEHIND
protected void DeleteBackground_click(object sender, EventArgs e)
{
foreach (ListViewItem itemRow in this.ListView2.Items)
{
var checkBtn = (HtmlInputCheckBox)itemRow.FindControl("checkbox1");
if (checkBtn.Checked)
{
string fileName = ("~/Members/images/BG/" + checkBtn.Value);
if (fileName != null || fileName != string.Empty)
{
if ((System.IO.File.Exists(fileName)))
{
System.IO.File.Delete(fileName);
}
}
}
}
}

These 2 lines
if ((System.IO.File.Exists(fileName)))
System.IO.File.Delete(fileName);
must be
if (System.IO.File.Exists(Server.MapPath(fileName)))
System.IO.File.Delete(Server.MapPath(fileName));
P.S.
It makes no sense to check if (fileName != null || fileName != string.Empty) because fileName is never null or empty.

certainly that the id="checkbox1" is rename by the renderer for not to have the same Id in item listView. Check the generated html.

Send information stored in a repeater to email recipient?

I would like to take all information stored in a repeater and place it in the body of an email message for sending. Basically, it's a product order form (which also makes use of a repeater) that sends users to an order review page with a form at the bottom that allows them to send the order information to someone else. I am allowed to set up the order information as a table. I have everything working, and my code successfully sends emails. However, I am not sure how to pull the order review repeater's contents into the message body for an email.
Any suggestions/tips are appreciated! Thanks!

I think this answer has what you're looking for. Basically, you can use javascript to send the html to the server in order to include it in your email:
asp.net get html controls in code behind
Also, make sure you include a ValidateRequest="false" on the page in order to post back html

if someone else has same problem and the repeater object has no image this solution is simple and easy instead of trust to a client javascript feedback !!
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =new HtmlTextWriter(stringWrite);
Repeater1.RenderControl(htmlWrite);string emailContent = stringWrite.ToString();
