I have a TreeList object that allows inplace editing. Two of the columns are TemplateColumns that display using a label but edit using a RadComboBox. When I press the edit button everything works fine (my drop downs load and everything) but when i press Cancel or Update after editing the system throws a "Failed to load viewstate" error. Treelist code below:

                <telerik:RadTreeList ID="rtl_Content" runat="server" 
                    AutoGenerateColumns="False" DataKeyNames="ID" ParentDataKeyNames="ID_Parent" Skin="Office2010Blue" EditMode="InPlace">
                    <ExportSettings ExportMode="RemoveControls"><Pdf PageHeight="11in" PageWidth="8.5in"></Pdf></ExportSettings>
                    <Columns>
                        <telerik:TreeListBoundColumn DataField="ID" UniqueName="column" Visible="False">
                        </telerik:TreeListBoundColumn>
                        <telerik:TreeListBoundColumn DataField="ID_Parent" UniqueName="column1" Visible="False">

Not sure if it makes a difference but the whole thing is inside a RadPageView

The thread title pretty much covers it;

but i've got a PagerStyle-Position="Bottom" because i want the user to scroll past the items in the grid before being able to change page.
but i'd also like to display the item count at the top of the grid ; # items in # pages

Sure this is very simple to do,

Thanks

Hi,
RadTreeView expands a node by clicking the plus button or by double clicking the text node.
I want to change this by just simple click on plus or text.
I tried this by handling the ClientNodeClicked event but it's not working
<script language="javascript"> function ClientNodeClicked(sender, eventArgs) { var node = eventArgs.get_node(); node.toggle(); } </script>
I used the load on demand server side. when i clicked the text  the plus button changed to minus and when i click on minus button it open the node and next time i redo the same operation on the same node  it works (because is already loaded).
please help.

Hi,

I want to disable all dates in my datepicker control except the first and the last date of the month.

I tried this code but this does not help:

protected void Calendar_OnDayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)
        {
            DateTime dt = e.Day.Date;
            DateTime dtFirst = new DateTime(dt.Year, dt.Month, 1);
            DateTime dtLast = new DateTime(dt.Year, dt.Month, 1).AddMonths(1).AddDays(-1);

            if (e.Day.Date != dtFirst.Date)
            {
                RadCalendarDay calendarDay = new RadCalendarDay();
                calendarDay.Date = e.Day.Date;
                calendarDay.IsSelectable = false;
                rdpBeginDate.Calendar.SpecialDays.Add(calendarDay);
            }
        } 

aspx:

<telerik:RadDatePicker ID="rdpBeginDate" runat="server">
                        <Calendar UseRowHeadersAsSelectors="False" UseColumnHeadersAsSelectors="False" ViewSelectorText="x"
                            runat="server" OnDayRender="Calendar_OnDayRender">
                           
                        </Calendar>
                        <DatePopupButton ImageUrl="" HoverImageUrl=""></DatePopupButton>
                        <DateInput EnableEmbeddedSkins="false" Enabled="false">
                        </DateInput>
                    </telerik:RadDatePicker>

Please help.

Hi,

I have a requirement where I have a RadDock with 2 zones.
I want to load all docks on it initially and then set for each container its own refresh time.
For example dock A will refresh in 5 minutes. Dock B will refresh in 20 minutes.
I want to do this with no postback - everything updates seamlessly. How do I do this?

Note: I have the latest 2011 telerik version.


Update: I have tried using webservice and javascript to populate the docks but found a problem.
The types controls within my docks are TagCloud, Graph and Treeview. I found that if I use webservice and javascript
I can't populate my tag cloud because I have to bind it as a RadTagCloudItem.


Thank you so much,

In rad editor, if i click  cut,copy and paste image buttons it shows please click ctrl + x for cut etc.. Please help me, Suppose i click  cut image button the selected text must be cut. what i do for it?

I have two radrotators, a horizontal scroller with 4 images at the bottom, and a single 'main' image radrotator at the top. I have it set up to display the disappearing item in the bottom scroller to the main image section as it moves forward. Is it possible to have the main image radrotator change based on the index of the lower one while still using the 'slide show' or 'automatic advance' rotator type? Or running two rotators off the same timer would help. After a couple minutes they get out of sync. I set both rotators to have the same scrollduration and frameduration. If this is possible, can you please offer a sample. Thanks!

Currently, my RadChart's datasource receives what a method returns (a request LINQ to SQL). What i return is more precisely

I would like to display underneath the X Axis a field of this objet ( a name for instance )

How is it possible to chose between the fields of an object those i want to use for my histogram

Thanks in advance for your help
