I have a related combo box inside a form view insert item template that is returning the error message of "'regionsComboBox' is null or not an object".

I suspect that the issue is related to my use of the $find syntax of the 2nd combo box in the .aspx code, but cannot see it.

Can anyone see/help me with my error?

Here is my .aspx code:

    
                <script type="text/javascript"> 
        
                    var regionsComboBox; 
        
                    function pageLoad() { 
        
                        regionsComboBox = $find('<%#((FormView)Container).FindControl("RadComboBox2").ClientID %>'); 
        
                    } 
        
                    function LoadRelatedRegions(combo, eventArqs) { 
        
                        var item = eventArqs.get_item(); 
        
                        regionsComboBox.set_text("Loading..."); 
        
                        if (item.get_index() > 0) { 
        
                            regionsComboBox.requestItems(item.get_value(), false); 
        
                        } 
        
                        else { 
        
                            regionsComboBox.set_text(" "); 
        
                            regionsComboBox.clearItems(); 
        
                        } 
        
                    } 
        
                    function ItemsLoaded(combo, eventArqs) { 
        
                        if (combo.get_items().get_count() > 0) { 
        
                            combo.set_text(combo.get_items().getItem(0).get_text()); 
        
                            combo.get_items().getItem(0).highlight();

FindControl on WebUserControl

Hey,

I am in a big hurry by my boss. I need a way to find a control that is on a webusercontrol via javascript. I have tried document.getelementbyid and $find('<% RadControl.ClientId %>') and nothing is working properly. If anyone can get back to me really quick I would greatly appreciate it.

RadDateTimeColumn TimePicker

Hi,

I have following datetime column:

<

telerik:GridDateTimeColumn PickerType="TimePicker" DataField="DrivingMinutesFromLastCity" HeaderText="Driving Time (MM)"

SortExpression="DrivingMinutesFromLastCity" DataType="System.DateTime" UniqueName="DrivingMinutesFromLastCity" DataFormatString="{0:HH:mm}" >

</telerik:GridDateTimeColumn>

now in the edit / insert form I have to enter only minutes in the form of HH:MM e.g. 00:50 . But in edit mode I have a small timeview button and when i type time 00:50 and press tab it converts it into 12:50 AM on the edit form. Time is represented in correct format (hh:mm) in the grid because i have setup dataformatstring. Now two questions:
1) How can I remove that TimeView button in the Edit mode?
2) How can I setup the input format for datetimecolumn , so that it should enter the time as it is entered e.g. 00:50 and not 12:50 AM.

Your help in this will be highly appreciated.

Cheers,
Ali

Problem with persisting state in cookie.

Hi

I have implemented the radpanel bar, and using the "SPNavigationProvider" i SharePoint (MOSS 2007). I have set PersistStateInCookie to True in order to keep the menu in the right state when clicking on the links in the menu, but when I go to another site which doesn't have the rad panel bar, the panelbar on the page I left will be in the same state as I left when I open that site again. I want the menu to reset to default when I visit other sites. Is that possible?

Another problem that I have is that the menu doesn't expand when I hyperlink from another site. It just stays the way it was. Is it possible to make the menu expand when I link to a "point" in the menu?

Please advise :)

This is my code

    
            <telerik:RadPanelBar  
        
                    Runat="server"   
        
                    DataSourceID="SPNavigationProvider"   
        
                    AllowCollapseAllItems="true" 
        
                    Skin="WebBlue"   
        
                    ExpandMode="SingleExpandedItem"   
        
                    PersistStateInCookie="True" 
        
                    CollapseDelay="300"   
        
                    EnableTheming="True"   
        
                    Font-Bold="False"   
        
                    ExpandDelay="300"   
        
                     EnableViewState="true" 
        
                    Width="215px">  
        
                     <CollapseAnimation   
        
                      Type="Linear"   
        
                      Duration="100">  
        
                     </CollapseAnimation> 
        
                     <ExpandAnimation   
        
                      Type="None" 
        
                       Duration="100">  
        
                     </ExpandAnimation> 
        
                   </telerik:RadPanelBar>

[Solved] RadDatePicker fails when moved to RadGrid AJAX

This RadDatePicker calendar control works in standard ASP INSERT record form.

          <td style="width:90px;">
            <TRad:RadDatePicker ID="dpDATE_INSTALLATION_INSERT" runat="server"
                                SelectedDate='<%# Bind("DATE_INSTALLATION","{0:d}") %>' AutoPostBack="False">
              <Calendar ID="Calendar2" runat="server" Skin="Outlook" ShowRowHeaders="false"
                        BorderStyle="Solid" BorderWidth="1px" BorderColor="Black"
                        TitleStyle-Backcolor="PaleGoldenrod"></Calendar>
              <DateInput ID="DateInput2" runat="server"
                         DateFormat="dd-MMM-yyyy" DisplayDateFormat="dd-MMM-yyyy" ></DateInput>
            </TRad:RadDatePicker>
          </td>

In the insert parameter I use the DateTime datatype.

When moved to AJAX Rad Grid form it fails when attempting to insert new record inthe Grid Form with error

"Conversion from string "" to type 'Date' is not valid."

I did not have to handle NULL or zero-length strings before.
