AJAX UpdatePanel lost focus

01-12-2010

Hi There,
I'm writing web application VB VS2008 with ajax. My page has user control
and textboxes. I group the textbox together and have 3 <asp:updatePanel ...
updatemode="Conditional"> each group has about 6 textboxes each textboxes
has AutoPostBack=true when I go to the third textbox with focus on, I cannot
type any characters to the box. Please helps. Thanks.

Hi Madison,

I have made a test application based on your description. After testing it,
I found that if we type some value into the first TextBox and then click
the second one, the cursor would disappear and we cannot type value into
the second one. Please tell me whether this behavior is the same to what
your mentioned.

If so, let me explain the cause of the behavior first.

We type some values into the first TextBox and then click the other place
of the window, the page would be refreshed because we set the AutoPostBack
property of the TextBox with true. Although we click the second TextBox,
the application would run the server side post back firstly whether these
controls are inside the UpdatePanel or not. The cursor which is inside the
second TextBox would disappear because the page's post back. This is the
default setting by the ASP.NET Life-cycle.

If these TextBoxes are placed into an UpdatePanel, we cannot see the
refresh of the page, so, the cursor's disappearance would be weird.

To make a workaround, we can set the AutoPostBack property with false. In
the second TextBox's client side click event, doPostBack and store the
current TextBox into a HiddenField. In the end, set the focus() function
after the asynchronous request is ended.

Refer to this sample:
<%@ Page Language="vb" AutoEventWireup="false"
CodeBehind="TestUpdatePanel.aspx.vb"
Inherits="_44456996.TestUpdatePanel" %>

<asp:TextBox ID="TextBox5" runat="server"
onclick="TextBoxOnClick(this)" AutoPostBack="false"></asp:TextBox><br />

onclick="TextBoxOnClick(this)" AutoPostBack="false"></asp:TextBox><br />
</div>
</ContentTemplate>
</asp:UpdatePanel>
</div>

<script type="text/javascript">

Sys.WebForms.PageRequestManager.getInstance().add_ endRequest(
function(sender, e) {
if ($get("HF1").value) {
var textbox = $get($get("HF1").value);
textbox.select();
textbox.focus();
}
});

function TextBoxOnClick(tb) {
if ($get("HF1").value != tb.id) {
$get("HF1").value = tb.id;
__doPostBack(tb.id, "");
}
}

</script>

</form>
</body>
</html>

Note that, to make these script run correctly, please place the script tag
under the ScriptManager control.

Another choice is set the AutoPostBack property with false and use a Button
to make a post back.

Meanwhile, I think these tutorials of the UpdatePanel can help you use it
and understand the AJAX function more clearly:

Thank you for your reply.
Here is my coding and problems that I try to do

<asp:UpdatePanel ID="UpdatePanel4" runat="server" UpdateMode="Conditional">

</table>
</ContentTemplate>
</asp:UpdatePanel>

The textbox for no.6 will have the total values of 1-5 and everytime the
value change the line 6 total will get update. The AutoPostsBack need to set
to true for re-calculate the line 6. Each textbox 1-5 have the the
TextChanged event that call the function to calculate the total then follow
by ScriptManager1.SetFocus(textboxname.ClientID) to set focus on the next
box. I can see the cursor at the next textbox but I cannot enter any values
to the box. This is only one group of the textbox, I will have more group of
textbox familiar to this in the page. I cannot use the button to calculate
because it means that users must click button everytime they enter the
values.

Any suggestion would be appreciate. Thanks.

Hi Madison,

I have explained that if we set the AutoPostBack with true, the focus of
TextBox would always disappear by the page's reloaded. Although we can set
focus on the Control which makes this post back by using the ScriptManager
class setFocus method, there is no way to know which control is clicked.

So, I think we have to set the AutoPostBack with false to enable the client
side behavior. As a workaround, we can use the Timer control to make a post
back and calculate the sum for TextBox6.

Refer to this:

Hi Madison,

I have modified some of my code, maybe this behavior can be more smoother.
I use a HiddenField to store the clicked TextBox's ID and then setfocus
back in the Timer's tick event.

Hi Zhi-Qiang Ni,

Thank you for your sample codes. I created new page and pasted your sample
and run. It did not work for me. I still have the same problem when I try to
enter the values into the textbox.

Hi Zhi-Qiang Ni,

Thank you for your help. Your samples for using the client side give me the
idea that I will switch my coding to use javascript for display the total
check and validation. I still have the server side validation before saving
to database. I thought that AJAX will help me with less coding but I guess
not. I hope that the new release VS2010 will make the things better. Thank
you again for your helps.

Hi Madison,

Thanks for your understanding of my supporting. The Ajax does help us
enable the asynchronous post back and partial refresh of the page with less
coding. However, the problem-we cannot stay the cursor in the client side
TextBox after a PostBack - is a default behavior whether we use the
UpdatePanel or not. I have explained the reason of it in my last reply. The
page needs to reload after the first TextBox is on blur. So, it's easy to
focus back to the first TextBox but hard to remember the client side click
of the next TextBox.

You can enjoy the other convenient and useful functions of the ASP.NET AJAX
and AjaxControlToolkit:
