Two thumb slider

Hi guys,

New slider looks very tasty (in fact it all does) but can we have a two thumb version of the slider. Very useful for specifying numeric ranges ie. ring size > 4 and ring size < 8

Cheers,

Pete

RadGrid esdatasource and dropdownlists - cannot access selected dropdown value when inserting

Hi,
I'm relatively new to the Radgrid and EntitySpaces. I know that they work extremely well together but I've been stumped for a few hours today with a problem. I've got a rad grid that is bound to an esDataSource, the datasource has a field that is a lookup value. I can bind the grid to the initial datasource and at this stage insertion and editing works fine. However, when I use a template column to add an dropdown control for the look up field (binding it in the ItemDataBound event handler), I can edit values well but when I insert new values though the lookup values are saved as empty values. I cant seem to grab the lookup dropdown value during the insert event.

Any suggestions would be helpful. Sample code or examples would be appriciated.

Here's my code:

<asp:Panel ID="pnlBreadcrumb" runat="server">

</asp:Panel>

<asp:Label ID="lblMessage" runat="server" Visible="false" Text="No list configuration found" />

<telerik:RadGrid ID="grdLevelValues" runat="server" GridLines="None"

AllowAutomaticInserts="True" AllowAutomaticUpdates="True"

DataSourceID="datListValues" AutoGenerateColumns="False"

onitemcommand="grdLevelValues_ItemCommand"

onitemdatabound="grdLevelValues_ItemDataBound"

onitemcreated="grdLevelValues_ItemCreated"

AllowSorting="True"

AllowPaging="True"

PageSize="25"

>

<HeaderContextMenu EnableAutoScroll="True"></HeaderContextMenu>

<MasterTableView datakeynames="IdBusinessUnit" datasourceid="datListValues" CommandItemDisplay="Top" EditMode="InPlace">

<Columns>

<telerik:GridBoundColumn DataField="BusinessUnitName" HeaderText="Business Unit"

UniqueName="column1">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="State">

<HeaderTemplate>

<asp:Label ID="lblStateNameHeader" Text="State Name" runat="server"></asp:Label>

</HeaderTemplate>

<ItemTemplate>

<asp:Label ID="lblStateName" runat="server" Text='<%# Eval("UpToAddressStateItemByIdState.State") %>' />

</ItemTemplate>

<EditItemTemplate>

<asp:DropDownList ID="ddlStateName" runat="server"></asp:DropDownList>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridEditCommandColumn></telerik:GridEditCommandColumn>

</Columns>

<EditFormSettings>

<EditColumn UniqueName="EditCommandColumn1"></EditColumn>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

<cc1:esDataSource ID="datListValues" runat="server"

onescreateentity="datListValues_esCreateEntity"

onesselect="datListValues_esSelect"

AutoPaging="true"

AutoSorting="true"/>

code behind:

dropDownList.DataTextField = "State";

dropDownList.DataValueField = "IdState";

//Find the selected index by assuming that the ddl datasource will maintain the order inwhich its items were added.

int ddlSelectedIndex =0;

foreach(AddressStateItem state in states)

Support for Japanese?

I have version 2008.3.1125.20 of the Telerik RadControls for ASP.NET AJAX.

Does some newer version of Telerik.Web.UI.dll support Japanese language in the chart? Currently, all I get is squares showing up in place of the actual characters.

Thanks so much for your help.

Export to Excel

I'm exporting a radgrid to Excel successfully. This is my code

gvwMaterial.ExportSettings.ExportOnlyData = true;

gvwMaterial.ExportSettings.IgnorePaging = true;

gvwMaterial.ExportSettings.OpenInNewWindow = true;

gvwMaterial.ExportSettings.Excel.Format = GridExcelExportFormat.Html;

gvwMaterial.ExportSettings.FileName = String.Format("File_{0}_{1}_in_{2}.xls", aaa, bbb.ToString(), ccc.ToString());

gvwMaterial.MasterTableView.ExportToExcel();

When Excel is opened, numbers with decimals, (percents like 0.12), are rounded to 0 or 1
How I can to format this columns?

Thanks

Filters in RadGrid not working when page loads for first time

Hi! I have a RadGrid which uses the FilterTemplate with a RadComboBox in GridBoundColumns. When the page initially loads all of the filter options in the RadComboBox are not listed, however, if the page is refreshed all the options appear in the filter.

Currently the SQL statement used to initially populate the filter is in the Page_Load method, and is outside of the 'IF Not IsPostBack' logic.

A method to refresh the combo boxes gets called in the RadGrid1_PreRender event handler. This method takes the original SQL statement and appends a where clause which contains the value selected in the combo box by the user, after which a call to RadGrid1.MasterTableView.Rebind() is made. The actual filtering does work as expected.

I was wondering if someone could provide some insight on how the filtering works in regards to a page initially loading, and if there is a better place to put the logic.

Thanks!

List Box not scrolling with page elements

I'm using the basic features of the list box (Q2 2009) and the functionality seems to work fine. I am having an issue with how it handles page resizing and div scrolling.
1. when I resize the browser window (IE 7) - the list box does not move and it overlaps the div border, causing it to cover the footer content.
2. when I scroll the div - all other controls move up or down, but the list box stays put.

I have it sitting in a <div> that has overflow set to auto and it's height set dynamically. The same div contains several Labels.

The short and sweet version of the aspx...

    
            <div id="MainDiv">   
        
            <telerik:RadAjaxPanel> 
        
            <div id="MultipageDiv">   -- this div is set to overflow:auto in a stylesheet;   
        
            <telerik:RadMultiPage> 
        
            <telerik:RadPageView ID="RadPageViewCustomers" runat="server">   
        
            <div id="ViewPageDiv" >              
        
            <asp:Table ID="Table1" runat="server" Width="800px">   
        
            <asp:TableRow> 
        
            <asp:TableCell>   
        
            <telerik:RadListBox>

Any ideas?
