you can cancel post back using the Ajax.

get the instance by following

var obj=Sys.WebForms.PageRequestManager.getInstance()

then check if this is Async postback and check with the element id that triggers the post back you can abort the post back.

obj.abortPostBack();

put your rating star control inside the update panel not the whole page. post your design code here so that i can identify the issue.

arya.anu 13-Dec-12 2:09am

<asp:UpdatePanel ID="UpdatePanel1" runat="server" >
<contenttemplate>
<div class="NewRating">
<span style="float: left; margin-bottom: 10px; width: 130px; margin-right: 10px">Clean:</span>
<ajaxToolkit:Rating ID="Rating1" runat="server" CssClass="ratingStar" CurrentRating="1"
EmptyStarCssClass="Empty" FilledStarCssClass="Filled" MaxRating="10" StarCssClass="ratingItem"
Style="float: left; margin: 0px; position: static; margin-left: 50px;" WaitingStarCssClass="Saved"
Width="131px" AutoPostBack="false" önChanged="Rating1_Changed">

<div style="clear: both">
</div>
</div>

it seems ok so far.post "Rating1_Changed" event code.

arya.anu 13-Dec-12 2:16am

protected void Rating1_Changed(object sender, AjaxControlToolkit.RatingEventArgs e)
{
Evaluate_Rating1(int.Parse(e.Value));
}

Solution 2

Add this
protected void Page_Load(object sender, EventArgs e)
{
Rating1.Attributes.Add("onclick", "return false;");
}
