Hi,

Post your code.

Re: avoid refresh in a button click event

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>

<table id="main" style="margin-top: 0px; margin-left: auto" cellspacing="0" cellpadding="0"
        align="center" bgcolor="#ffffff" border="0" width="100%">
        <tr>
            <td>

<asp:CheckBox ID="ChkAdmin" Text="ADMIN" runat="server" AutoPostBack="true" OnCheckedChanged="ChkAdmin_CheckedChanged"
TabIndex="3" />
</td>

</tr>

<tr>

<td>

<asp:Button ID="btnBack" runat="server" AccessKey="B" CssClass="RSMenuItemColor"
                                OnClick="btnBack_Click" onmouseout="this.className='RSMenuItemColor'" onmouseover="this.className='RSMenuItemOverColor'"
                                TabIndex="5" Text="Back" />
                             <asp:Button ID="btnReset" runat="server" AccessKey="R" CssClass="RSMenuItemColor"
                                OnClick="btnReset_Click" onmouseout="this.className='RSMenuItemColor'" onmouseover="this.className='RSMenuItemOverColor'"
                                TabIndex="5" Text="Reset" />

Hi,

What you want to achive exactly???

Don't write onclick event of button. Page won't get postbacked!!!

Re: avoid refresh in a button click event

Hi raja_durai1,

I am not sure whether I have understood your meaning. Assuming that you don't want to refresh the CheckBox when you click the Button, you can use UpdatePanel control. However, you need to modify your code and move the CheckBox out of the UpdatePanel. In order to help you understand, I have written a demo below:

In the .aspx

<asp:ScriptManager ID="ScriptManager1" runat="server" />
        <asp:UpdatePanel runat="server" id="UpdatePanel" updatemode="Conditional">
            <ContentTemplate>
                <asp:Label runat="server" id="DateTimeLabel1" />
                <asp:Button runat="server" id="UpdateButton1" onclick="UpdateButton_Click" text="Update" />
            </ContentTemplate>
        </asp:UpdatePanel>
        <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="true"
            oncheckedchanged="CheckBox1_CheckedChanged" />
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

In the code behind

 protected void Page_Load(object sender, EventArgs e)
    {
        TextBox1.Text = DateTime.Now.ToString();
    }
    protected void UpdateButton_Click(object sender, EventArgs e)
    {
        DateTimeLabel1.Text = DateTime.Now.ToString();       
    }

    protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
    {

    }

Please test it locally. When you click the Button and CheckBox, you will find the difference.

Note that when you set AutoPostBack="true", the event CheckBox1_CheckedChanged will occur and make a postback. When you set it false, it willn't do a postback. In addition, I would suggest you to use IE Develop Tools to debug step by step.

Best wishes,

The page will postback regardless of whether or not the button has an OnClick handler attached to it.
