RadMenu with StylesManager

Good morning Telerik Team,

In our application, we disabled Telerik stylesheet CDN and enabled stylesheet combined in the stylesmanager. When we open a page with RadMenu control, the menu mess up and we found one webresource throw 500 error. Is there any setting we need set?

/Telerik.Web.UI.WebResource.axd?d=C6CXK_NKqeRQozdHamsVHY4iEh2-WHZ0hR2lZ4lb0QXhxNgPaCKJi-mbpKFkZJFyaLS96jrWiH-vS8d1mRcnCLyJDy45wzq4xT8qZIVpH1iN6XQB3Ms8R0ovsOLLDEf275IHDg2&t=635025536200000000&compress=1&_TSM_CombinedScripts_=%3b%3bTelerik.Web.UI%2c+Version%3d2015.3.930.40%2c+Culture%3dneutral%2c+PublicKeyToken%3d121fae78165ba3d4%3aen-US%3af59d7c8d-045a-4b22-9f9c-e124aae8c608%3a92753c09%3a91f742eb%3aed2942d4%3a8cee9284%3aed057d30%3aa3b7d93f%3a1f65231b%3a7f7626a2%3a9e1572d6%3ae25b4b77%3a45085116

Thanks in advance,

InitialPath - Invalid characters in folder name.

Code FileExplorer.InitialPath = "~/Documents"; or on any folder throws message box "Invalid characters in folder name."
This bug was introduced in Telerik.Web.UI_2010_2_826 and later. All previous releases until Telerik.Web.UI_2010_2_817_hotfix.zip was all right in such a functionality.
Check it, please.

Resolution has been found. Thanks.

Expand/Collapse issues using Grouping

We recently upgraded from the ASP.NET Classic controls to the ASP.NET AJAX controls on one of our largest projects. One of our requirements was to maintain current behavior and appearance on all controls. Unfortuantely, we are having a fair amount of trouble with RadGrids.

We are using a RadGrid with server side grouping and expand/collapse functionality enabled. When a user expands/collapses an item, the ItemCommand event is fired which updates a session variable to keep track of which items are expanded. When the user returns to the page, the ItemDataBound method determines whether or not to expand a GridGroupHeaderItem depending on the values stored in the session variable. The good news is that expanded/collapsed states are rendering correctly on subsequent page loads. Unfortunately, if the user then expands or collapses any item, all GridItems that were expanded in the ItemDataBound disappear. The groups that these items belong to are still expanded and items that have been expanded after page load are not affected. Clicking on the group again collapses the group with the missing items, and the next click re-expands it revealing the items that were missing.

Does anyone have any idea why our items are being hidden? I included snippets from the aspx and aspx.cs files below. Specific names and details have been changed to protect the innocent.

Clear datepicker filter from radgrid

I am attempting to do something similar to this but slightly different. I am attempting to put a raddatepicker in a radgrid filter template with the textbox disabled so the user cannot enter a date and must use the datepicker button. Then I want to have an imagebutton next to the datepicker that will clear the filter. The datepicker works as expected and filters the radgrid appropriately but clicking the imagebutton does not clear the filter. Here is my code for the column including javascript:

<telerik:GridTemplateColumn DataField="openDate" DataType="System.DateTime" HeaderText="Open Date"

SortExpression="openDate" UniqueName="openDate" ReadOnly="True" FilterControlAltText="Filter open date">

<HeaderStyle Width="150px" />

<FilterTemplate>

<telerik:RadDatePicker ID="OpenedRadDatePicker" runat="server" ClientEvents-OnDateSelected="OpenDateSelected"

<ClientEvents OnLoad="OnClientLoad" />

</DateInput>

<DatePopupButton HoverImageUrl="" ImageUrl="" />

<ClientEvents OnDateSelected="OpenDateSelected" />

</telerik:RadDatePicker>

<asp:ImageButton ID="ClearOpenDateButton" runat="server" ImageUrl="images/cancel.gif"

AlternateText="Show All" ToolTip="Clear Open Date Filter" Style="vertical-align: middle"

Height="15px" Width="15px" OnClientClick="ClearDateSelected(); return true;" />

<telerik:RadScriptBlock ID="OpenDateSelectedRadScriptBlock" runat="server">

<script type="text/javascript">

var datePicker;

function OnClientLoad(sender, args) {

datePicker = sender;

}

function ClearDateSelected() {

datePicker.clear();

}

function OpenDateSelected(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var date = FormatSelectedDate(sender);

var nextDate = GetNextSelectedDate(sender);

if (date != "" && nextDate != "") {

tableView.filter("openDate", date + " " + nextDate, Telerik.Web.UI.GridFilterFunction.Between);

}

else {

tableView.filter("openDate", "", Telerik.Web.UI.GridFilterFunction.NoFilter);

}

var formattedDate = "";

var date = picker.get_selectedDate();

if (date != null) {

var dateInput = picker.get_dateInput();

formattedDate = dateInput.get_dateFormatInfo().FormatDate(date, "M/d/yyyy");

}

return formattedDate;

}

function GetNextSelectedDate(picker) {

var formattedDate = "";

var date = picker.get_selectedDate();

if (date != null) {

date.setDate(date.getDate() + 1);

protected DateTime? SetOpenedDate(GridItem item)

{

string openFilter = item.OwnerTableView.GetColumn("openDate").CurrentFilterValue;

if (string.IsNullOrEmpty(openFilter))

{

return new DateTime?();

}

else

{

return DateTime.Parse(openFilter.Substring(0, openFilter.IndexOf(" ")));

}

When I press the ClearOpenDateButton while the radgrid is filtered, I do get the partial page postback. The RadGrid_ItemCommand event is properly fired, the LinqDataSource Selecting and Selected events run correctly as well and in the Selected event, it does indeed indicate in the arguments that all rows are being returned from the datasource but the grid doesn't get updated. I'm thinking it's just an update problem but I'm not sure why it works fine with the raddatepicker but not the imagebutton.

Also when I press the ClearOpenDateButton, the datepicker does clear the selected date as expected.

Rotator Styling

I've bumped up against an issue where in the basic rotator, my button on the right overlaps the content. This happens only in Chrome, and it looks fine in all other browsers. I haven't added any styling and I'm doing it on a blank test page. So either the existing default styling is off, or there is some setting (like my widths?) that I need to adjust. Any help is appreciated.

<telerik:RadRotator RenderMode="Lightweight" ID="RadRotator1" OnItemDataBound="RadRotator1_ItemDataBound" runat="server" Width="930px" Height="200px"

RotatorType="Buttons" ItemHeight="200" ItemWidth="896" >

<Items>

<telerik:RadRotatorItem></telerik:RadRotatorItem>

</Items>

<ItemTemplate>

test test test

</ItemTemplate>

</telerik:RadRotator>

How to register to OnClientDropDownOpened in the javascript

Hi,

I have to do add a class to all the combo box items which has checkbox in the page and do some other manipulation on it. So right now am doing on page load using the $('.RadComboBoxDropDown').find('label') this code. But this will not solve my issue completely since the combo items can change dynamically. So i thought of doing it on drop down open event. But I can't find how to register for this event in javascript ?

Thanks
