Using Visual Studio 2008

The use for this is in a Timesheet entry webpage where a 2 week period is in
view, using the DataList ItemTemplate only.

The popup's targetcontrol is the Hours textbox(16 total & 16 popupcontrol's;
one for each of them), the popup is a text box to enter a memo about the
time entry.

This works really well for the user & each popup is properly bound to the
correct row and target textbox without having to select the row first, but
the popup control has to be located in the ItemTemplate and ajax does the
rest.

Here is the problem, Ajax does not hide the popup control until after the
pageload. That means 16 popup's per row that are visble until the
popupextendercontrol hides them one at a time; very slowly.

If I set the popup's visible to false that works to hide them on pageload,
but I will need to do an onclick javascript to make them visble again (if
that is possible) on the Hours textbox, which I don't know how to do.

Any thoughts as how to achive what I am doing with the popup within the
Datalist ItemTemplate; I just want to have my Cake & eat it Too! Is that
bad?
Maybe the new ListView would work better?
Thanks
John

Hello John,

From your post, my understanding on this issue is: you wonder how to make
the popup controls invisible before the whole page load. If I'm off base,
please feel free to let me know.

As you see, the popup controls are visible before the whole page is loaded.
It is because PopupControlBehavior.js registers the page load event and
calls the hidePopup method in its event handler:

// Called automatically when a page load/postback happens
_close : function(result) {
¡* ¡* ¡*
// Hide the popup
this.hidePopup();
}

Therefore, the popup controls will be hidden only when the whole page is
loaded.

The method this.hidePopup calls "this._popupBehavior.hide();" in
PopupBehavior.js, which internally calls $common.setVisible(element,
false); The method setVisible is in Common.js. When the second parameter
(value) is false, it calls element.style.display = 'none'; and
element.style.visibility = 'hidden' to hide the control.

To resolve your problem, we can add the style ""display:none;
visibility:hidden" to the popup control so that the controls are invisible
before page load.

<asp:TextBox runat="server" ID="popupTextBox" style="display:none;
visibility:hidden"></asp:TextBox>

Please have a try and let me know the result. If you have any other
concerns or need anything else, feel free to let me know.

I gave it a try and from the visual point of view it works, but in the
background it is still going thru the process of hiding them again & I
suppose activating them too.

I have it in an update panel with a progress bar, which stays active for
quite some time & even though you can begin entering time, the popups only
become available as it cycles thru each row to process them.

Maybe the hiding is only part of the problem and each has to be made active
regardless?

If so is there a way to use just one popupcontrol inside or outside of the
DataList & assign it to the Time Textbox thru an onclick JavaScript event? I
would need to assign the Popups binding too.

Thanks
John

Hello John,

What do you mean by "in the background it is still going thru the process
of hiding them again"? After the page is loaded, the method hidePopup will
be called on each popup control. Because we have already set the visibility
of the popup controls as false (style="display:none; visibility:hidden"),
this operation (hidePopup) takes no effect.

>If so is there a way to use just one popupcontrol inside or outside of
>the DataList & assign it to the Time Textbox thru an onclick JavaScript
>event? I would need to assign the Popups binding too.
Would you let me know whether the term 'popupcontrol' refers to the
popupcontrolid: the textbox or the popupcontrolextender?
If you meant the popup control, the answer is yes based on my test.
If you maant the popupcontrolextender, the answer is no. It will throw an
exception that says "The TargetControlID of 'TextBox1_PopupControlExtender'
is not valid", because the target control Id varies in different rows of
the data list.

Last but not least, I would suggest posting Ajax Control Toolkit issues in
ASP.NET forum:
http://forums.asp.net/1022.aspx
The reason why we recommend posting appropriately is you will get the most
qualified pool of respondents, and other partners who the newsgroups
regularly can either share their knowledge or learn from your interaction
with us. Thank you for your understanding.

Have a nice day!

Hi, thanks for you reply,

There must be more involved than just hiding each control on page
load/postback, because even though all the rows display right with the
popups hidden, the popup control does not work on all the rows until the
ajax prorgress bar for the update panel goes away. For example: row 1 works
1st & then works its way to that last row, which then will display the popup
too when I click it, but not until the updatePanel acitity has ended, but it
takes a little while. If I do anything that then requires a postback the
same reprocessing occurs again.



I was referring to the PopupControl as the Textbox that would popup when the
Textbox in the DataList is clicked. If I could get that down to Just one
Control per Row instead of the 16 I have now, it would be faster maybe, so
long as I could onclick:



Reset the PopupControlExtender's TargetControlID to the one I am clicking

Rebind the Textbox that pop's up to the correct corresponding Binding, which
is a memo field.



Can that be done with JavaScript? Would I need just one PopupControlExtender
too then if that is viable, I now have 16, one for each popup TextBox that
is clicked as its TargetControlID?



So if Below is the 1st Clicked Textbox , when clicking of the 2nd TextBox:
<%# Eval("M1") %> would be reset to <%# Eval("M2") %>



and TargetControlID="txtDay1" would be reset to TargetControlID="txtDay2"





<asp:TextBox ID="MyPopupMemo" runat="server" Text='<%# Eval("M1") %>'

TextMode="MultiLine" Width="220px"></asp:TextBox>



<cc1opupControlExtender ID="PopupControlExtender1" runat="server"

PopupControlID="MyPopupMemo" Position="Bottom" TargetControlID="txtDay1">

</cc1opupControlExtender>







I did notice that the asp.net forum has a lot more activity after I posted
to this one.

Thank,

John

Hello,

According to the description, you expect that a PopupControlExtender
control can be dynamically bound to a target control which is click on. I
don't think this is an expected behavior when the community
design&developed the PopupControlExtender. Have you tried the ASP.NET forum
(http://forums.asp.net/1022.aspx)? Because Ajax Control Toolkit is
monitored by the community, I think you will get a better explanation and
resolution there.

Happy New Year!

Hi,

If you put the html that you want to display in a panel and then
assign the CssClass attribute according to below, then the panel will
not initially be displayed
<style>
.cssInitalTag
{
visibility:hidden;
position:absolute;
}
</style>

<aspanel ID="pnlPop" runat="server" CssClass="cssAvailMod">
Here is the popup control HTML
</aspanel>
