Updating Objects

Hi$0$0$0$0Any help appreciated. I'm binding a radGrid to an object I have written. I can display data from the object fine. I have set the property AllowAutomaticUpdates = False so that I can handle updates to the object within the UpdateCommand event. However, whilst in that event I can't seem to find the actual data that has changed. Perhaps someone could point me to the data or have I not understood something?$0$0$0$0$0Thanks.$0$0Luke$0$0$0$0

Second level to open RadWindow?

I set up a page based on this example where windows can be opened with tab links:

http://demos.telerik.com/ASPNET/Prometheus/Window/Examples/RadWindowAndMDI/DefaultVB.aspx

I have a menu that uses RadMenu with a drop down hierarchy similar to this:

I got my tablist to show sub links like the menu.

<telerik:RadTabStrip OnClientTabSelected="OnClientTabSelected" ID="RadTabStrip1" runat="server" SelectedIndex="2" Skin="Office2007">
                  <Tabs>
                    <telerik:RadTab runat="server" Text="Home" NavigateUrl="HomeTest.aspx">
                    </telerik:RadTab>
                    <telerik:RadTab runat="server" Text="Home2">
                    <Tabs>
                            <telerik:RadTab runat="server" Text="Home2 Page" NavigateUrl="Default2.aspx"></telerik:RadTab>                                            </telerik:RadTab>
                    </Tabs>
                    </telerik:RadTab>
                    <telerik:RadTab runat="server" Text="Home3" Selected="True">
                        <Tabs>
                            <telerik:RadTab runat="server" Text="Home3" NavigateUrl="Default3.aspx"></telerik:RadTab>
                        </Tabs>
                    </telerik:RadTab>
                </Tabs>
            </telerik:RadTabStrip>

However, it only wants to open a window when you click on the main tabs, but I only want windows to open for the sub pages.

Is this possible?

Disable fonctionnality in RadDatePicker

Hi,

Is it possible to disable the DateInput style modification inside a RadDatePicker ?
I would like to disable some fonctionnality like HoverStyle and FocusStyle.

In my case, I have a RadDatePicker with a customvalidator and a ValidatorCalloutExtender attached to it :

    
            <telerik:RadDatePicker ID="RadDatePicker1" runat="server"> 
        
                            </telerik:RadDatePicker> 
        
                            <asp:CustomValidator ID="CustomValidator1" runat="server" Text=" " ControlToValidate="RadDatePicker1" 
        
                                ClientValidationFunction="RadDatePicker1_Validate" ValidateEmptyText="true" /> 
        
                            <cc1:ValidatorCalloutExtender ID="ValidatorCalloutExtender7" runat="server" Enabled="True" 
        
                                TargetControlID="CustomValidator1" HighlightCssClass="validatorCalloutHighlight"> 
        
                            </cc1:ValidatorCalloutExtender>

When the RadDatePicker is empty, I change its textbox background color :

    
            <script language="javascript" type="text/javascript"> 
        
                function RadDatePicker1_Validate(sender, args)  
        
            {  
        
                var picker = $find("<%= RadDatePicker1.ClientID %>").get_dateInput();  
        
                var textbox = $find("<%= RadDatePicker1.ClientID %>").get_textBox();  
        
                if (picker.get_value().length == 0)  
        
                {  
        
                    textbox.className = "validatorCalloutHighlight"; 
        
                    args.IsValid = false;  
        
                }  
        
                else  
        
                {  
        
                    args.IsValid = true;  
        
                }  
        
            }  
        
                </script>

Everything is fine until I hover or focus the textbox. In those cases, the default skin of the RadDatePicker is back.

That's why I would like to disable the hover and focus fonctionnality. Is there a way to do it ?

Thank you
Ab

RadGrid, Custom Paging and Ajax -- Oh My!

I have a RadGrid that is populated from an object DataSource (bound in code-behind). I have the sutom pagin all working except it is posting back instead of making the paging call through Ajax. I have a RadAjaxManager on the page that sets the AjaxUpdatedControl to the RadGrid and I even have a RadAjaxLoadingPanel set up and have tol the AjaxManager to use that as it's Default Loading Panel. What am I missing. I've read all the examples (most of which are old enough that they don't use the RadAjaxManager or the RadAjaxLoadingPanel.

Any help will be appreciated.

[Solved] Paiting multi-nodes with different color

Hi!

I want to create a client function that "paints" an array of nodes.
It should look like a traditional selection but in a green color for example.
Its not a selection really, I just want to paint some nodes green and when the users clicks over a green-selected node the node should go back to its original state.

Thanks!

Export to PDF when Grid in an UPdatePanel and Tab Control

I read an old post on the forum that explains what is needed when the RadGrid is contained within an Update Panel in order for the export functionality to work.
(http://www.telerik.com/help/aspnet-ajax/grdexportwithajax.html).

So I added the Triggers to the UpdatePanel but this didn't work since my Grid (and export button) was contained within a tab of a Tab Control

This resulted in error:
A control with ID 'btnExport' could not be found for the trigger in UpdatePanel 'upTabs'.

For a workaround I had to move the Export button outside of the tabcontrol but this isn't the desired behavior.

Any suggestions?

Thanks!
Debbie

[Solved] EmtyValuesMode.Zero

I’m using VS 2008, framework 3.5, and RadChart for ASPNET AJAX Q1 2008.

I’m binding the some data to the RadChart; one of the fields = NULL. I’m trying to disable the “Approximation”, i.e. set EmtyValuesMode.Zero through code behind. How can I do that?

Thanks,

[Solved] Footer aggregate causes "Specified Cast is not valid." exception

Whenever I try to set Aggregate="Sum" for an integer column, I get the "Specified Cast is not valid." exception. I've tried all kinds of things, but always get the exception. It works fine with Decimal columns.

These cause an exception:

    
            <rad:GridNumericColumn DataField="EstQty" HeaderText="Est. Qty." 
        
                        UniqueName="EstQtyColumn" Aggregate="Sum" NumericType="Number" 
        
                        DataType="System.Int32" DataFormatString="{0:N0}">  
        
                 <HeaderStyle HorizontalAlign="Center" /> 
        
                 <ItemStyle Width="6em" /> 
        
            </rad:GridNumericColumn> 
        
            <rad:GridNumericColumn DataField="FinalQty" HeaderText="Final Qty." 
        
                        UniqueName="FinalQtyColumn" Aggregate="Sum" NumericType="Number" 
        
                        DataType="System.Int32" DataFormatString="{0:N0}">  
        
                 <HeaderStyle HorizontalAlign="Center" /> 
        
                 <ItemStyle Width="6em" /> 
        
            </rad:GridNumericColumn>

While this works fine:

    
            <rad:GridNumericColumn DataField="Postage" HeaderText="Postage" UniqueName="PostageColumn" 
        
                        NumericType="Currency" DataType="System.Decimal" Aggregate="Sum" 
        
                        FooterAggregateFormatString="{0:C}">  
        
                 <HeaderStyle HorizontalAlign="Center" /> 
        
                 <ItemStyle HorizontalAlign="Right" /> 
        
            </rad:GridNumericColumn>

I'm using Q2 2008 SP1, btw.
