Load all Items Silently [optimize]

Hi All,

I have a combobox which is on the edittemplate of a gridview. The configuration of my combobox is Automatic Load on Demand. Every time I click the edit button on my gridview the combobox loads all items then expands the list. Is there way to load the items silently by not expanding the list and disable the control to prevent the user in entering text while loading for the first time.

The combobox has the setting filtering="contains" and contains ~30,000 items from an sqldatasource. It's slow, Is there a way to speed up the loading of this huge amount of list.

Thank You,
Aivan

How to access all fields in row for custom validator

Hola,

I'm currently developing a form using a radgrid to allow users to register multiple guests for an event. Each row in the grid is a guest and the grid is editable to allow the users to add their own guests.

Two of the columns are Age & GuestOption

    
            <telerik:GridTemplateColumn UniqueName="Age" HeaderText="Age (Child Only)"> 
        
                            <ItemTemplate> 
        
                                <asp:Label runat="server" ID="lblAge" Text='<%# Bind("Age") %>'></asp:Label> 
        
                            </ItemTemplate> 
        
                            <EditItemTemplate> 
        
                                <asp:TextBox runat="server" ID="editAge" Text='<%# Bind("Age") %>' Width="20px"></asp:TextBox> 
        
                                <asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="editAge" runat="server" ValidationExpression="^[0-1]?[0-7]$" ErrorMessage="Whole numbers, under 18"></asp:RegularExpressionValidator> 
        
                            </EditItemTemplate> 
        
                        </telerik:GridTemplateColumn> 
        
                        <telerik:GridDropDownColumn DataField="GuestOptionsID" DataSourceID="GuestOptionsDataSource" 
        
                            HeaderText="Options" ListTextField="GuestOption" ListValueField="GuestOptionsID" 
        
                            UniqueName="GuestOption" ColumnEditorID="GuestOptionsIDEditor"> 
        
                        </telerik:GridDropDownColumn>

    
            <asp:SqlDataSource ID="GuestOptionsDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:edu_yale_som_alumnireunion_connectionstring %>" 
        
                ProviderName="System.Data.SqlClient" SelectCommand="SELECT [GuestOptionsID], [GuestOption] FROM [GuestOptions] WHERE Visible='true' order by DisplayOrder"> 
        
            </asp:SqlDataSource>

I have age being validated so that if they enter an age is needs to be less than 18. But, I also need to validate based on the option the select in the GuestOption drop down.

I'm trying to use a custom validator, but I need to be able to have access to both the value in the Age column & the value in the GuestOption drop down. Is there an easy way for me to access both those values during the validation? I can just do this all after the post the form, but I would prefer to do this with validation so that they cannot enter invalid data from the get go.

thanks,

-Jon

FilterMenu overflow problem

Currently if there is not enough room to fit the filter options inside of the grid it will extend beyond the top of the grid.

I want to make the list extend beyond the bottom instead... I tried changing the Expand Direction property for FilterMenu with no luck.

How can I do this?

[Solved] RadWindow with GridView

I dont know why I guess its because we are on IE6, but the normal GridView control is a lot quicker than the RadGrid retutning the same data, so I'm stuck with the GridView.

I've implemented RadWindows to give me modal pop ups for data from the Gridview rows.

But what is happening is this - with RadAjaxManager the pop up would only show once, I then removed the RadAjaxManager and the pop up appears once after a postback. ie on load it works, I then hit the buton again and the page postsback (no ajax) then the pop up works again.

This is my code behind in the rowdataBound event:

    
                        'SET UP BUTTON FUNCTIONS  
        
                        'set View Demog button action  
        
                        Dim ibd As ImageButton = CType(e.Row.FindControl("btnViewDemog"), ImageButton)  
        
                        ibd.Attributes("href") = "#"  
        
                        ibd.Attributes("onclick") = [String].Format("return ShowDemog('{0}');", e.Row.DataItem("id"))

And this is my client side javascript:

    
                        function ShowDemog(id) {  
        
                            alert("Boo");  
        
                            window.radopen("ShowDemog.aspx?Patient_ID=" + id, "ShowDemog");  
        
                            return false;  
        
                        }

In the pop up page after processing I call this:

    
            ClientScript.RegisterStartupScript(Page.GetType(), "mykey", "CloseAndRebind();", True)

Any help would be appreciated

share data among panels before refreshing

Hi everybody,
I'm testing Telerik controls in order to use them in a wss/moss custom application. I need help passing data between different Panels.

My final goal is to make refreshing different web parts when i click on a control on a single web part passing some data to the other web parts before they render again.

I designed my app with 2 panel: a menu area and a content area.
The idea was to customize the master page where I put:

1 asp:ScriptManager
1 telerik:RadAjaxManager

    
                <asp:ScriptManager runat="server" ID="ScriptManagerMain" /> 
        
                 <telerik:RadAjaxManager ID="RadAjaxManagerMain" runat="server"> 
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="CustomPanelMenu"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadAjaxLoadingPanelMain"></telerik:AjaxUpdatedControl> 
        
                                <telerik:AjaxUpdatedControl ControlID="CustomPanelMain"  /> 
        
                             </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                        <telerik:AjaxSetting AjaxControlID="CustomPanelMain"> 
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="RadAjaxLoadingPanelMain"/> 
        
                                <telerik:AjaxUpdatedControl ControlID="CustomPanelMenu" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager>

1 asp:Panel to be used for menu purposes

    
                            <asp:Panel ID="CustomPanelMenu" runat="server"> 
        
                                <WebParts:TestMenu001 runat="server" ID="TestMenu001_1" Title="MenuSx" __MarkupType="vsattributemarkup" __WebPartId="{0ce525f0-089d-4f57-902a-78d4b87b34b9}" WebPart="true" __designer:IsClosed="false" /> 
        
                          </asp:Panel>

1 asp:Panel where I put the standard moss content placeholder "PlaceHolderMain" for main content web parts
1 telerik:RadAjaxLoadingPanel to make the application more interactive

    
            <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanelMain" runat="server"/> 
        
            <asp:Panel ID="CustomPanelMain" runat="server"> 
        
                <asp:ContentPlaceHolder id="PlaceHolderMain" runat="server"> 
        
                </asp:ContentPlaceHolder> 
        
            </asp:Panel>

As you can see in the first code block, I configured the RadAjaxManager in order to update the panels.
I had to pass data between the web part I will put in the panels:
For example: when I click on a control in the web part put in the menu panel I want the web part put in the CustomPanelMain will refresh with the id I chose.

I try to put data in the Page.Session, but I tested that the refresh on the main web part will start before the data is written in the menu web part.
What am I wronging? What do you suggest to do that?

Many thanks,
RF
