RadContextMenu attributes adding problem

We are using RadContextMenu in our product.
I am using Contextmenu within Repeater, The problem I am facing is, I have tried to add client side events in itemdataboud and itemcreated but nothing works.
I am adding it like:
contextMenu.Attributes.Add("OnItemClicked","return test1();");

But the test1 has never fired.
Note here that I don't care about sender and args parameters.
Can someone please tell me how to add client side attribute in server side code, although the above statement worked for other radcontrols like RadNumericTextbox.

Any help will be greatly appreciated, I have tried to find solutions for many hours now but nothing help, please.

RadTabStrip + RadMultiPage + RadAjaxManager Problem

I have a scenario where I have a RadTabStrip with 2 tabs and a RadMultiPage with 2 pages. In the first page I have a RadGrid and the second page is a form. I am using RadAjaxManager to ajaxify the page. I want to be able to click an edit link from the RadGrid and have the multipage and tabstrip change to the form page.

The problem I am having is when I click on edit, the RadMultipage changes, but the RadTabStrip does not. If I take the RadAjaxManager out then it works correctly.

I have replicated the problem using a simple setup with just buttons in each page. Clicking the button should change both the RadTabStrip and RadMultipage.

Here is my aspx code

    
                <telerik:RadTabStrip ID="RadTabStrip1" runat="server"   
        
                    MultiPageID="RadMultiPage1">  
        
                    <Tabs> 
        
                        <telerik:RadTab runat="server" Text="List">  
        
                        </telerik:RadTab> 
        
                        <telerik:RadTab runat="server" Text="Form">  
        
                        </telerik:RadTab> 
        
                    </Tabs> 
        
                </telerik:RadTabStrip> 
        
                <telerik:RadMultiPage ID="RadMultiPage1" runat="server">  
        
                    <telerik:RadPageView ID="RadPageView1" runat="server">  
        
                        List View<br /><br /> 
        
                        <asp:Button ID="Button1" runat="server" Text="Go to Form View" /> 
        
                     </telerik:RadPageView> 
        
                    <telerik:RadPageView ID="RadPageView2" runat="server" Width="100%">  
        
                        Form View<br /><br /> 
        
                        <asp:Button ID="Button2" runat="server" Text="Go to List View" />

                </telerik:RadMultiPage> 
        
                <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server"   
        
                    Skin="Default" Transparency="1">  
        
                </telerik:RadAjaxLoadingPanel> 
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"   
        
                    DefaultLoadingPanelID="RadAjaxLoadingPanel1">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="RadTabStrip1">

                                <telerik:AjaxUpdatedControl ControlID="RadTabStrip1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadMultiPage1" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                        <telerik:AjaxSetting AjaxControlID="RadMultiPage1">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadTabStrip1" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadMultiPage1" />

                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager>

Here is the code behind

    
                Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
                    If Not Page.IsPostBack Then 
        
                        RadTabStrip1.SelectedIndex = 0  
        
                        RadMultiPage1.SelectedIndex = 0  
        
                    End If 
        
                End Sub 
        
                Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click  
        
                    RadTabStrip1.SelectedIndex = 1  
        
                    RadMultiPage1.SelectedIndex = 1  
        
                End Sub 
        
                Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click  
        
                    RadTabStrip1.SelectedIndex = 0  
        
                    RadMultiPage1.SelectedIndex = 0  
        
                End Sub

If I take out the RadAjaxManager it works correctly.
Using the RadAjaxManager the RadTabStrip does not update. Any ideas?

p.s. I have tried this with version 2009.2.701.20, 2009.2.826.20, 2009.3.1103.20 of Telerik.Web.UI

Filter problems.

I have a RadGrid driven by a LinqToSQL data layer that returns a dataset for binding. I also have custom paging implemented. Under normal conditions the data layer only returns a page's worth of data, 10 to 15 records. If a filter is entered, custom paging is turned off and the entire data set is returned. Normally this is not a burden as the total data set is usually around 100 records or so and the users know that filtering slows things down a bit.

However I've just seen some behavior I can't explain. The field most likely to be filtered on is a varchar(max), although for display purposes only the first 75 char are displayed.

The problem is as follows: The filter works but only if a Refresh of the grid is done first. (i.e. doing 2 filters in a row will not work.) Otherwise it seems to hang.
I've seen this same problem using both old and new versions of the RadGrid. (Our production version is running a 2012 version. I have the latest on my development machine.)

What could I be missing?

As currently implemented the Refresh button calls the following code.

RadGrid1.MasterTableView.SortExpressions.Clear();

// Clear all filters
foreach (GridColumn column in RadGrid1.MasterTableView.OwnerGrid.Columns)
{
column.CurrentFilterFunction = GridKnownFunction.NoFilter;
column.CurrentFilterValue = string.Empty;
}

RadGrid1.MasterTableView.FilterExpression = string.Empty;

RadGrid1.Rebind();

The value selected in "target" property of hyperlink manager of rad editor is not getting saved properly.

Hi,
we are facing issue in radeditor hyperlink manager.
I tried setting the target window for the link using hyperlink manager. No matter which option you choose, the link only opens in a 'new window'. The other choices available in hyperlink manager such as 'same window ' or 'parent window' do not work.

by default 'target' value is getting saved as 'new window', when i am choosing any other options like 'parent window 'and after clicking ok it is modified as 'new window'. when I reopen the hyperlink manager I am only getting 'new window' but not the previous option what i have chosen.
can any one help me in finding the solution. currently we are using telerik version '2012.2.912.35' and i have given the EditModes="Design".

Thanks.

RADWindow Skin

Hi,

I have a MasterPage that opens a RADWindow in Model Window. Then when the user click on a new button in the RadWindow, it opens another RadWindow on top with no problem. However I can not set the skin of the 2nd RADWindow.

function GetRadWindow() {

var oWindow = null;

if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz az well)

return oWindow;

}

function NewStatus() {

var oManager = GetRadWindow().get_windowManager();

setTimeout(function () {

var winId = "Win" + Math.random().toString();

var winPage = "AddStatus.aspx" + winId;

var oNew = oManager.open("", "Window2");

oNew.setUrl(winPage);

oNew.SetSize(750, 550);

oNew.set_visibleStatusbar(false);

oNew.set_title("Status Screen");

oNew.Skin = "Forest";

oNew.set_keepInScreenBounds(true);

oNew.set_enableShadow(true);

oNew.set_destroyOnClose(true);

oNew.set_animation(Telerik.Web.UI.WindowAnimation.Slide);

oNew.set_initialBehaviors(Telerik.Web.UI.WindowBehaviors.None);

oNew.set_behaviors(Telerik.Web.UI.WindowBehaviors.Close);

oNew.add_close(OnClientCloseHandler);

oNew.setActive(true);

oNew.set_modal(true);

oNew.Show();

}, 0);

}

Am I missing something? What is the correct way of getting the result needed ?

Dynamically change GridColumnGroup text

I have a simple radgrid that has one GridColumnGroup that displays above 4 bound columns.
------------------------------
<ColumnGroups>
<telerik:GridColumnGroup HeaderText="Reporting Period" Name="ReportingPeriod"/>
</ColumnGroups>

<telerik:GridBoundColumn DataField="Numerator" HeaderText="Numerator" UniqueName="Numerator" ColumnGroupName="ReportingPeriod" />

That is all, there is no "grouping", etc. It is purely for display.

Is there a way to change the HeaderText of the GridColumnGroup dynamically? I cannot seem to be able to access it on itemdatabound, or any other way. I want to change the text to a "value", but there is no way to reference it? (to the reporting period dates dynamically)
Any help would be appreciated.
Thanks

Select multiple timeslot

Hi,
I am kinda stuck with multiple timeslot selection, like that of outlook. Although it highlights all the selected timeslot but then I am not able to find out the date selected.

Since I am using my own UserControl I disabled Insert/Edit/Delete of Radscheduler, so FormCreated wont' be fired.
I am using RadAjaxManager for server side event. In my Client event
OnClientTimeSlotContextMenuItemClicked="OnClientTimeSlotContextMenuItemClicked"

function OnClientTimeSlotContextMenuItemClicked(sender, eventArgs) {  var menuItem = eventArgs.get_item();  var timeSlot = eventArgs.get_slot();  if (menuItem != null) {  var selectedMenuItem = menuItem._properties._data.value;  if (selectedMenuItem == "createTimesheet") { } else if (selectedMenuItem == "createTodo") { } else if (selectedMenuItem == "AllDay") {  var radWindow = $find("<%=rWindowAppointmentInsert.ClientID %>"); radWindow.show();  var startDate = new Date(timeSlot._startTime);  var duration = timeSlot.get_durationInMinutes();  var arg = "Type=AllDay,Start=" + timeSlot._startTime.toDateString() + " " + startDate.getHours() + ":" + startDate.getMinutes(); arg += ",Duration=" + duration; $find("<%=rAjaxMgrScheduler.ClientID %>").ajaxRequest(arg);  return false; } else if (selectedMenuItem == "Insert") {  var radWindow = $find("<%=rWindowAppointmentInsert.ClientID %>"); radWindow.show();  var startDate = new Date(timeSlot._startTime);  var duration = timeSlot.get_durationInMinutes();  var arg = "Type=Insert,Start=" + timeSlot._startTime.toDateString() + " " + startDate.getHours() + ":" + startDate.getMinutes(); arg += ",Duration=" + duration; $find("<%=rAjaxMgrScheduler.ClientID %>").ajaxRequest(arg);  return false; } else

{ <br>                    <br>                    }<br>                }<br>

return false; }

I cannot find how to get start and end date.

Thank you
