User Controls in ListView are losing their viewstate

Hi,
I have custom user controls dynamically added to a RadListView.
The user controls themselves govern their sub controls user access (hidden, readonly, etc...)
Although X Controls are Created, X - Y controls remain after the ItemDataBound event is done firing based on the user's access. (where Y is between 0 and X).

The problem is, on Postback the User Controls lose their viewstate... why is this happening?

I can do Everything in the ItemCreated Event and it functions as intended; however, since that is fired on every single Postback it is doing unnecessary calculations going through and figuring out which fields are visible, readonly, and which controls are even part of the List,

Am I stuck doing everything in the ItemCreated Event?

Or is their a way to Just Do my Processing and DataBinding in the ItemDataBound Event? <--(This would work now, if the controls retained their viewstate on postback)

Thanks,
~Patrick

RadTextBox Line Break Issues

I am using the RadTextBox with MultiLine enabled. The issue i am having is that i need to determine whether or not there have been changes from what is being held in the database, and if there has been changes then display a warning message. Chrome, Safari, Firefox all work fine; however, in Internet Explorer and Opera new lines are changed from Line Feeds (\n) to a Carriage Return followed by a Line Feed (\r\n). Therefore, even if a person doesn't make changes to the RadTextBox, Internet Explorer/Opera will see the string coming from the database (the string with just \n's) different from what's in the RadTextBox (the string with \r\n's).

I have attached images of what is being displayed, along with what is being seen in the RadTextBox (ContentEditor.Text) and what is being seen in the database (CurrentContent). Also, below should be a snippet of the aspx code for my RadTextBox:

<telerik:RadTextBox runat="server" ID="ContentEditor" Height="200px" Width="580px" TextMode="MultiLine"
Wrap="true" ></telerik:RadTextBox>

Is there anyway to fix this, or is there a reason why this is happening?

Thanks again for the help,

- Pat

DatePicker Script Error

Hello,

I have a page with a datepicker control as well as a textbox. When the date changes in the datepicker, I would like to change the text in the textbox. I do not want to postback during this process so I have ajaxified the datepicker control with the ajaxmanager. The problem is that when I select a date, the page stops responding and I get the IE message "A script on this page is causing Internet Explorer to run slowly. If it continues to run, your computer may become unresponsive. Do you want to abort the script?" How can this problem be resolved? My code is below:

---------------------------------------------------------------------------

<

rad:RadAjaxManager ID="RadAjaxManager1" runat="server">

<rad:AjaxSetting AjaxControlID="dateWeekStartDate">

<rad:AjaxUpdatedControl ControlID="dateWeekStartDate" />

<rad:AjaxUpdatedControl ControlID="txtWeekEndDate" />

</UpdatedControls>

</rad:AjaxSetting>

</AjaxSettings>

</rad:RadAjaxManager>

<

div class="row">

Date:

</div>

<rad:RadDatePicker ID="dateWeekStartDate" runat="server" Skin="None" OnSelectedDateChanged="dateWeekStartDate_SelectedDateChanged">

</Calendar>

</rad:RadDatePicker>

</div>

Date:

</div>

<asp:TextBox runat="server" ID="txtWeekEndDate" ReadOnly="true"></asp:TextBox>

</div>

</div>

-----------------------------------------------------------------------------------------------------------------------

protected

void dateWeekStartDate_SelectedDateChanged(object sender, Telerik.WebControls.SelectedDateChangedEventArgs e)

{

txtWeekEndDate.Text = dateWeekStartDate.SelectedDate.ToString();

}

------------------------------------------------------------------------------------------------------------------------

Any help would be greatly appreciated.

Thank you,

Jennifer

Two Way Sorting only

Hi Support,

I have two Question:
Q. 1 => I have a situation where I need only two way sorting that is Ascending OR Descending...
In my grid if I click on column header it works like:

First Click : Ascending Order
Second Click: Descending Order
Third Click: Sorting Removed

I want on third click it should sort it again Ascending order and so on....
An example will be great help.

Q.2. => I saw an example where you are handling 300,000 records in a grid that works at great speed. In that example you are binding data from some web service.
http://demos.telerik.com/aspnet-ajax/grid/examples/client/caching/defaultcs.aspx

I have 700,000 records for a report and SQL Server 2008 as back-end. I am binding from code behind using DataSet. It is working but it is very slow... it took almost 45 seconds to retrieve data for one screen.

Can you suggest me how can I speed it up like your demo example.

Thanks

Getting reference to RadPanelBar in IE

Hi,
I have a radpanelbar with PersistStateInCookie="True". It's is populated dynamically in code behind. I want to write a javascript code to check if there is no level 0 item expanded then it expands the last level 0 item. I have written the following code:

function ExpandFirst() {

var panelBar = $find("<%= _radpnlbarMenu.ClientID %>");

if (panelBar) {

var item = panelBar.get_expandedItem();

if (panelBar.get_expandedItem() == null) {

var items = panelBar.get_items();

if (items.get_count() > 0)

items.getItem(items.get_count() - 1).expand();

}

$(document).ready(function() {

ExpandFirst();

});

<telerik:RadPanelBar OnItemDataBound="RadpnlbarMenuOnItemDataBound" runat="server" ID="_radpnlbarMenu" ExpandAnimation-Type="InQuart" ExpandAnimation-Duration="500" CollapseAnimation-Duration="500" CollapseAnimation-Type="InQuart" Height="250px" ExpandMode="FullExpandedItem" PersistStateInCookie="True">

<DataBindings>

<telerik:RadPanelItemBinding Depth="0" Expanded="true" />

</DataBindings>

</telerik:RadPanelBar>

It works fine in Firefox but in IE the panelBar object is always null.
Is this the best way to do the trick?
Can you please help me?
