Persist node Enable/Disable across post back

This issue is related to another form post, but slightly different regarding maintaining state of the tree view nodes changed by client side code across post back.

I have four nodes w/Check boxes
A
B
C
D

When A is clicked, if it is checked, it will disable and uncheck every other node. If A is unchecked it will re-enable all other nodes.
What I have found is that if I check B, and then check A, post back, I get my expected result - only A checked with all others disabled and unchecked.
Now, if I uncheck A (which re-enables everything), on the next post back all the other nodes are once again disabled. As if the enable/disable did not persist across the post back (yet it did the first time?).

Code below (code behind is empty):

    
                function TVOnNodeChecked(sender, e)  
        
                { 
        
                    var Tree = $find('<%=rtvTest.ClientID %>'); 
        
                    var TreeNodes = Tree.get_allNodes(); 
        
                    var ClickedNode = e.get_node(); 
        
                    if (ClickedNode.get_value() == 1)  
        
                    { 
        
                        Tree.trackChanges(); 
        
                        for (var i = 0; i < TreeNodes.length; i++)  
        
                        { 
        
                            var thisNode = TreeNodes[i]; 
        
                            var thisNodeCB = thisNode.get_checkBoxElement(); 
        
                            if (thisNode.get_value() != 1)  
        
                            { 
        
                                if (ClickedNode.get_checked()) { 
        
                                    thisNode.set_checked(false); 
        
                                    thisNode.set_enabled(false); 
        
                                } 
        
                                else  
        
                                { 
        
                                    thisNode.set_enabled(true); 
        
                                } 
        
                            }             
        
                        } 
        
                        Tree.commitChanges(); 
        
                    }

SelectedItems returning zero

Have the following grid in my aspx page:

    
            <telerik:RadGrid id="gridMessages" runat="server" AllowSorting="True" OnNeedDataSource="gridMessages_NeedDataSource"

            </telerik:GridBoundColumn> 
        
            </Columns> 
        
            </MasterTableView> 
        
            <ClientSettings> 
        
            <Selecting AllowRowSelect="True" /> 
        
            </ClientSettings> 
        
            </telerik:RadGrid>

I'm attempting to set up a Hashtable to the values from the grid with the following code:

    
                    public List<Hashtable> getSelectedValues()  
        
                    {  
        
                        List<Hashtable> list = new List<Hashtable>();  
        
                        GridItemCollection items = gridMessages.SelectedItems;  
        
                        foreach (GridItem item in items)  
        
                        {  
        
                            Hashtable values = new Hashtable();  
        
                            ((GridDataItem)item).ExtractValues(values);  
        
                            list.Add(values);  
        
                        }  
        
                        return list;  
        
                    }

I can check any number of rows in the GridClientSelectColumn, but no matter what, gridMessages.SelectedItems is always zero. Any ideas?

Problem with break out from IFrame

Hi!

I'm trying to use the RadTabStrip to control the display of data in an IFrame in a Microsoft Dynamics CRM form. My application uses two TabStrips to filter out information displayed in the CRM IFrame. Both TabStrips are data bound to the CRM filtered database views. When the CRM form is loaded, my page is loaded OK in the IFrame. The top TabStrip is populated with two tabs, the tab text is correctly selected from the CRM database.

When I click the first tab, which has an ontabclick function (CS) that copies the label's text into another label used in the where clause in the data source for the second TabStrip, the page in the IFrame braks out and opens a new browser window outside the MS CRM application. Why does this happen, and is there a way to make my page stay inside the IFrame?

            DateTime firstday = datenow.AddDays(-1);
            DateTime endday = datenow.AddDays(2);
            DayOfWeek firstdayofWeek = firstday.DayOfWeek;
            DayOfWeek enddayofWeek = endday.DayOfWeek;
            RadScheduler1.FirstDayOfWeek = firstdayofWeek;
            RadScheduler1.LastDayOfWeek = enddayofWeek;

        }

This process what happens in the code of telerik and I can not change.
I need help for this problem.

Printing only works with first frame

Hello,

When I'm printing my webpage the image in the rotator only prints out properly when on the first frame. If any other frame is the active frame the image prints blank. Is there anyway to get it to print the second or third frame when the user clicks 'print' while that frame is showing?

Grid with Slider Paging, Throws exception while moving paging slider.

Hi,

I am doing POC on RADGrid with Slider paging.
But I am getting an exception as "Input string was not in a correct format." when I move / drags slider for paging. It's not working for me. I am attaching my ASPX and VB.Net code along I will appreciate if I can get feedback as early as possible.

We are planning to incorporate Telerik controls in our application for rich feel and high performance but only if I get rid of these kind of minor error which eats lots of head.

Default2006 skin still supported?

I ask because its not a choice on the skin demo, and more importantly, more and more css sprite images seem to be wrong in the last builds. For example, the icons on the AJAX spell check context menu now seem wrong. The alignment icons (like in table wizard) have been wrong for awhile.

RadScheduler Appointment Update

Hi

I am getting this problem. Please help me.

In my scheduler, if I add a new appointment, its getting added and reflected in the schedule.
If I drag or resize an appointment, it is getting updated and reflected in schedule. If I delete an appointment it also works fine.

Problem is: Suppose I am editing an appointment immediately after creation, The advanced editor is not getting opened. If I press refresh after adding an appointment and then editing it, then it opens.

Also if I am editing an appointment using advanced editor, the update is done in database, but it is not reflected in scheduler. I need to refresh the screen to see the update.

Note: I am using Telerik RAD controls Q3 2008 Trial version. I also have resource types (additional drop down lists) in my appointment.

Thanks.
