TimeSlotCreated event raised before and after page load event

Hi, during debugging with VS 2008 (Q2 2008 build 723) we remarked the following behavior:

On the first request to the page, we have the page load event called, and then a series of TimeSlotCreated event raised. Then if we cause a refresh of the scheduler using ajax (we click on the day or week button on the ajaxified scheduler) , we notice that the TimeSlotCreated event are fired before the page load event, and then again after the page load event, which caused us problems.

We noticed this after upgrading from the future build (708) to the release sp2 build (723). In the future build, the TimeSlotCreated event is always raised after the page load event.

We can fix our problem, but i'd like to know why the behavior is different (set of TimeSlotCreated raised twice in the latest build)

Thanks

Open RadWindow from code behind

I am using RadControl AJAX, I want to open a radwindow from code behind after some functions are handled, I try to use registerStartupScript as below:

string newWindowUrl = "Popups/Default1.aspx?WindowArgs=" + windowArgs;

string javaScript =

"<script type='text/javascript'>\n" +

"<!--\n" +

"var newwindow = window.radopen('" + newWindowUrl + "' +',' + 'RadWindow1');\n" +

"newwindow.focus();\n" +

"// -->\n" +

"</script>\n";

Page.ClientScript.RegisterStartupScript(t, "Email", javaScript);

and my aspx page is:

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false" EnableViewState="true"

ReloadOnShow="true" runat="server" Skin="Default" EnableShadow="false" >

<Windows>

<telerik:RadWindow ID="RadWindow1" VisibleTitlebar="false" runat="server" Behaviors="Close, Move, Resize" AutoSize="true" NavigateUrl="~/Popups/Default1.aspx">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

But it doesn't work. Any suggestions?

Thanks in advance!

Radwindow, can I go back to previous page?

Is there back/forward navigation like in a webbrowser. For example in the demo of Radwindow I can open up Google in a radwindow and do a search. If I click on a link how do I go back to the search results.

I could save the NavigateUrl property and reload that page when the user clicks a back button. I was just hoping it was built in.

Thanks,
Corey

How to call a Javascript function from RadGrid Update Button

Hello,

I have a Radgrid in my web application . When I edit a row in the Radgrid, I want to call a javascript function (which will get the geocodes ) from the update button. I know we can add the attributes if the button is on the form. But that is not the case now.

I am accessing that update button in the itemDatabound event like this

Dim editItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
Dim updateButton As ImageButton = DirectCast(editItem.FindControl("UpdateButton"), ImageButton)

Appreciate the Help
Thanks

[Solved] ObjectDataSource bound RadComboBox inside RadGrid

I have a EditFormSettings FormTemplate inside a RadGrid that contains two comboboxes:
(Looks something like this):

    
            <FormTemplate> 
        
                                <table> 
        
                                    <tr> 
        
                                        <td>

                                            <asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False" 
        
                                            CommandName="Cancel"></asp:Button></td> 
        
                                    </tr> 
        
                                </table> 
        
                            </FormTemplate>

Simple enough... There are two RadComboBoxes with two different ObjectDataSources applied. The ObjectDataSources look like this:

    
                <asp:ObjectDataSource ID="ObjectDataSourceInventoryName" runat="server"  
        
                    TypeName="Ams.Web.BackOffice.InventoryAdapter"  
        
                    DataObjectTypeName="Ams.Core.DomainObject.Inventory"  
        
                    OldValuesParameterFormatString="original_{0}" 
        
                    ConflictDetection="CompareAllValues" 
        
                    SelectMethod="GetInventoryForComboBox"> 
        
                 </asp:ObjectDataSource> 
        
                <asp:ObjectDataSource ID="ObjectDataSourceAttribute" runat="server"  
        
                    TypeName="Ams.Web.BackOffice.InventoryTypeAttributesAdapter"  
        
                    DataObjectTypeName="Ams.Core.DomainObject.InventoryAttribute_InventoryType"  
        
                    OldValuesParameterFormatString="original_{0}" 
        
                    ConflictDetection="CompareAllValues"  
        
                    SelectMethod="GetAttributeByInventoryId"> 
        
            <SELECTPARAMETERS> 
        
                            <asp:ControlParameter Name="aInventoryId" PropertyName="SelectedValue" ControlID="RadComboBoxInventoryName" /> 
        
                        </SELECTPARAMETERS> 
        
                 </asp:ObjectDataSource>

Note, the ObjectDataSource of interest is the second, as it has a dependency on the first for one of its SelectParameters. When the page loads, I get an error stating:

Could not find control 'RadComboBoxInventoryName' in ControlParameter 'aInventoryId'.

Basically, it reports that it cannot find the control for the aInventoryId parameter (as its not rendered on the page yet).
Is it possible to use ObjectDataSources with parameter dependencies inside an edit form? If not, is there a work around?
Thanks in advance,
Tim
PS. I've tried the $ sign trick some other have posted.. No dice. (Inspected the client "name" attribute for the input control of the RadComboBox --

ctl00$ContentPlaceHolderBody$mImportMappingGrids$RadGridOrigin$ctl00$ctl07$RadComboBoxInventoryName

Nope...
