Data entered in textbox not visible when back arrow used

In page-1 I have 8 textbox with a checkbox and a button. All these are inside update panel.
All textbox's have 'autopostback=false'. The checkbox is with 'autopostback=true'. Now, after filling all the textbox's (checkbox not ticked) I click the button. The page-1 is redirected to page-2. From page-2 I use back arrow button. Page-1 with data in Textbox's are displayed as it is.
Now, with same data I tick the checkbox (autopostback=true) and press that button. Page-2 is displayed. Now at page-2 I use the back arrow button. Page-1 is blank without any data in any of the textbox's!. If I keep the checkbox outside the update panel it works well but when I tick the checkbox the page goes to server and returns. How to find a solution for this? I want the checkbox to be inside the UpdatePanel. Should I have a separate UpdatePanel for thsis checkbox within the main UpdatePanel.

Can't you handle the CheckedChange functionality at client side? What exactly you are doing in that?

<asp:CheckBox ID="GuestChkBox" runat="server"
OnCheckedChanged="CheckBox1_CheckedChanged" Position="Absolute"
Checked="false" Text='Send to guest' AutoPostBack="true"
style=" z-index:1; margin-top:620px; margin-left:245px; font-size:larger; left: 215px; top: 124px; position: absolute;"
Width="153px" >

<asp:RadioButtonList ID="RadioButtonList6" runat="server"
RepeatDirection="Vertical"
style="z-index: 1; left: 610px; top: 745px; position: absolute; height: 35px; width: 262px"
AutoPostBack="True"
onselectedindexchanged="RadioButtonList6_SelectedIndexChanged">
<asp:ListItem>Deliver at the above address
<asp:ListItem>Deliver at a different address

protected void CheckBox1_CheckedChanged(Object sender, EventArgs e) // 'send to guest' check box
{

Panel4.Visible = true;
Label18.Visible = true;
if (GuestChkBox.Checked)
{

RadioButtonList6.Visible = true;
v_SendToGuestTag = "*";
v_sendtoguestyesorno = "Y";
}
else
{

v_sendtoguestyesorno = "N";
v_SendToGuestTag = "";
RadioButtonList6.Visible = false;
Panel1.Visible = false;
RadioButtonList6.Items.Clear();
RadioButtonList6.Items.Add("Deliver at the above address");
RadioButtonList6.Items.Add("Deliver at a different address");
Label183.Visible = false;
}

}

Try to all these things in client side.

With regard to that checkbox, how to do in client side?

Add a onclick client side event or simple attach jQuery event for checkbox. You can easily find the implementation through Google.

In that event try to achieve all the things you are currently doing in server side, which I guess you can easily do.

Which is the .net framework?

3.5

I dont think an nested updatepanel can be an option here.

JoCodes 27-Dec-13 10:22am

Handling it in Clientside is a good suggestion by Tadit. Or try placing the Checkbox outside the update panel and add an asynchronouspostback trigger for checkbox selection event.Try and revert.

I tried with asynchronouspostback trigger . It doesnt work.

JoCodes 27-Dec-13 10:44am

Can you show the markup code which tried?

<asp:UpdatePanel ID="UpdatePanel133" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GuestChkBox" />
</Triggers>
<contenttemplate>
<asp:CheckBox ID="CheckBox1" runat="server"
OnCheckedChanged="CheckBox1_CheckedChanged" Position="Absolute"
Checked="false" Text='Send to guest' AutoPostBack="true"
style=" z-index:1; margin-top:620px; margin-left:245px; font-size:larger; left: 215px; top: 124px; position: absolute;"
Width="153px" >

<asp:RadioButtonList ID="RadioButtonList1" runat="server"
RepeatDirection="Vertical"
style="z-index: 1; left: 610px; top: 745px; position: absolute; height: 35px; width: 262px"
AutoPostBack="True"
onselectedindexchanged="RadioButtonList6_SelectedIndexChanged">
<asp:ListItem>Deliver at the above address
<asp:ListItem>Deliver at a different address
