function deleteParentElement(n){
n.parentNode.parentNode.removeChild(n.parentNode);
}

<input type="button" önclick="deleteParentElement(this)" value="Remove this DIV" />

I tried this .. its working fine .. but I dont why but I am getting scrollbar to scroll divs added by user

And there is one more problem is that .. this function is deleting the div element .. but when user enter new comment .. the value again coming from database and old comment it gets displayed

because you have only deleted the element and not the comment... You will have to delete the comment also from database or if you want to keep history of the comment add a bit field to the database as isActive whose value will become false when deleted. And populate the comments using isActive=true in the where clause of you SQL

Can you post a new question with the code you have used both .aspx page and code page. I'll have no idea what you want unless I see your code. Considering this question has been solved by you.

<asp:Repeater ID="repNotes" runat="server">

<itemtemplate>
<div class="SummaryWrapper">
<div class="Summary_Title_WrapperText">
<div class="Summary_Title_Wrapper_Left">
Comment :
</div>
<div class="Summary_Title_Wrapper_Right">
<%# Eval("Comment")%>
</div>
</div>
<div class="Summary_Title_WrapperText">
<div class="Summary_Title_Wrapper_Left">

</div>
<div class="Summary_Title_Wrapper_Right">
<%# Eval("AddedByName")%>

Replace Input tag with a Link Button
<asp:LinkButton ID="btnDeleterepNotes" runat="server" CommandType="Del">Delete </asp:LinkButton >
Raise an event of repeater OnRowCommand you can do that by going to the design view clicking on the repater control and clicking on the Lighting type button on the top of properties window.
There you will find a list of controls for the repeater. Click in the Double click on the Onrowcommand and you will be redirected to the code page

Here Inside that event write following code

if(e.CommandType == "Del")
{
SqlConnection conn = new SqlConnection();
conn.ConnectionString= [Your Connection String];
conn.Open();
SqlCommand cmd = new SqlCommand(conn);
cmd.CommandType= CommandType.Text;
cmd.CommandText = [SQL DELETE STATEMENT HERE];
cmd.ExcecuteNonQuery();
conn.Close();
Response.Redirect("[Your Page]");
}

Actually there are many ways to do but this is the basic one. I dont mean to be rude but you basic are not clear. :)
