Intercept "Expand" event for nested views and process the expansion by hand

I am having a bunch of issues trying to use data sources with radGrid nested views, therefore, I was wondering if there is an event I can intercept when clicking on the expand arrow so that I can, myself, retreive the data and display it for that particular item.

Also, when I do this, where should I store the information I get on other expanded items? Use a generic list and put it in the view state? If so, how would I render the whole grid when the postback is received? How do I walk through the hierarchy and update those items which where previously expanded?

Thanks

Sal

Cascading Combo Boxes > How To Get the Third Combo To Update?

I have read the sample and it was very helpful, but I guess I am missing something, because I cannot get the third combo to update properly.

In the attached sample, I have 3 combos: Content Area, Teacher Name, Student Name

When a user changes the Content Area, I want both combos to refresh. It is a true cascade, because the teacher name also determines the list of students.

For demo purposes, I have made it so the students lat names start with the same letter as their teachers. So, if you select [Mathematics], not only should [Euler, Leonhard] appear (which it does), but also his first student [Edwards, Ernie]. This does not happen. The student list remains for the previous teacher, until you manually change that second combo.

I am sure this is simple -- I am probably missing something on the control that would trigger the update to the third combo -- but I've been struggling with this for a few days now and need a more experienced set of eyes.

Suggestions are much appreciated!

RadEditor long content printing issue

When the content inside a RadEditor in a form is more than one letter page long is not printing properly, creating one or more page breaks before printing the content. I guess it has to be with the IFrame. What can I do to print the content continuously as the rest of my form?

Thanks,

RadDateTimePicker Button Images Not Showing

I have a RadDateTimePicker that is hidden when the page is loaded but if the user selects a specific type of field to search against it then gets shown. When the control gets shown, the buttons for the date and time popups do not show. Weird thing is that if I put a seperate RadDateTimePicker control on the page they do show. This is a control that is hosted on a content page in case that would matter.

<telerik:RadDateTimePicker ID="SearchValueDate" runat="server" Calendar-ShowRowHeaders="false" Visible="false" TabIndex="4" >

</telerik:RadDateTimePicker

if (ddlSearchCriteria.SelectedValue == FilterOperator.DateOnlyRange.ToString()

|| ddlSearchCriteria.SelectedValue == FilterOperator.DateTimeRange.ToString())

{

lblStart.Text = GetString("CustomSearch.lblStart.StartDate.Text");

lblEnd.Text = GetString("CustomSearch.lblEnd.EndDate.Text");

lblStart.Visible = true;

lblEnd.Visible = true;

SearchValueDateEnd.Visible = true;

}

pretty straight forward stuff so I'm not sure where this is broken. Is there anything else I need to do to make this happen?

Radeditor Strip font not working when content paste from pdf document.

Hi,

RadEditor strip font not working when content paste from pdf document.

I am using the RadEditor (version: 2011.1.315.40) with edit form as a model popup.

Below is code snippet that I used in my application

<telerik:RadEditor ID="RadEditor1" runat="server" SpellCheckSettings-DictionaryPath="../RadSpellControl/TDF/"
   EditModes="Design" BorderStyle="None" BorderWidth="0px" Height="129px" Width="250px"
        ContentAreaCssFile="~/css/radeditor.css" OnClientPasteHtml="OnClientPasteHtml"
        OnClientLoad="InitialDescriptionText">
        <Tools>
            <telerik:EditorToolGroup>
                    <telerik:EditorTool Name="Bold" />
                        <telerik:EditorTool Name="Italic" />
                        <telerik:EditorTool Name="Underline" />
                </telerik:EditorToolGroup>
                <telerik:EditorToolGroup>
                        <telerik:EditorTool Name="InsertOrderedList" Text="Ordered List" />
                </telerik:EditorToolGroup>
                <telerik:EditorToolGroup>
                          <telerik:EditorTool Name="PasteFromWordNoFontsNoSizes" />
                 </telerik:EditorToolGroup>
        </Tools>
</telerik:RadEditor>

I have a client application that allows them to enter comments into the RadEditor with Bold, Italic, Underline and numbering option only. so when any content pasted in

RadEditor is strip all style and css except Bold, Italic, Underline and numbering option. that's thing working properly in when content paste from ms-word document for

IE and Firefox browser.

But when content copied and paste from any pdf document then it works only for IE properly with help of "Paste from Word, strip font" button.

but in Firefox, it remove(striped) all style and css with Bold, Italic, Underline and numbering option with help of "Paste from Word, strip font" button..

Could you let me know what is reason of it is not working when the contents are copied from pdf document?

Awaiting for response.

Regards,

Nimesh
