I've been exploring use of the Spreadsheet control. I followed an example which shows me how to define the provider and read from an XLS file in App_Data folder of ASP.NET application. Uses latest versions of UI/AJAX, VS2015, Azure, etc.

I am finding that simple spreadsheets load reliably.

Medium size ones take a few seconds to load, and then show a blank sheet, no error message.

See attachment for this error.

Large size ones take a long time and timeout.

I am wondering whether there are severe capacity and/or performance issues with the Spreadsheet control, or this behavior is a side-effect of reading a file within my app's directory.

Dear All,

      In  My Application I am using RadGrid Inside the RadWindow. In RadGrid i have used RadTextBox under Item Template. My Requirement is in my form when i will click the button radwindow will be displayed. But the actual problem is i cant set the focus inside the RadTextBox. Because RadGrid was located inside the RadWindow. I have tried the following code. But it doesnt help. I am looking for your valuable help & suggestions.

  private void FocusOriginalRow(short index)
        {
            foreach (GridDataItem gridItem in rGrdItemDet.Items)
            {
                if (gridItem.ItemIndex == Convert.ToInt32(index))
                {
                    gridItem.FindControl("txtSPCS").Focus();
                    return;
                }
            }
        }

I have a page with a RadEditor on it.  I have a test button that posts causing a model RadWindow to open over the RadEditor. When the page refreshes, the editor gets its text but then disappears when the RadWindow opens over it. The RadEditor text reappears when the RadWindow is closed.

The test window is open from a javascript function that is initiated by code.

OpenTestWindow is

I need to be able to look at the editor contents while the RadWindow is open.

This is a very strange problem

We were given the below style from a marketing firm who is redesigning our primary website.  It is needed for other area's of the site but it breaks the styling within our RadTreeView.  Without changing the below style how can we get our RadTreeView back to normal?  I have attached what is happening when the style is applied.

I have been using two Menu controls with Metro Touch skin applied.

Last year I modified the CSS to remove borders, background and a few other elements, as you can see in the first screen shot (2015)

Sometime this year, in another project with more recent releases, now on the latest Q2, I find that there are vertical lines, as shown in screen shot 2016.

The CSS is identical for both.

All I need is to modify an unknown style that puts the vertical line there, at the right of each of the two menus.

Hi I need retain the Satete of the panelbar after navigation, but also I need use databind this to SiteMapDataSource

This is the code that I use, but not Working, (the idea is expand the parent and set to selected the item node that match with the url (Or cointains this))

what is bad in the code?

<telerik:RadPanelBar RenderMode="Lightweight" OnItemDataBound="RadPanelBar1_ItemDataBound"  
                ID="RadPanelBarMenu" ViewStateMode="Enabled" EnableViewState="true" runat="server"  Width="100%" ExpandMode="SingleExpandedItem"
                DataSourceID="SiteMapDataSource1" DataFieldID="id" DataFieldParentID="ParentId" DataTextField="">
                <DataBindings>
                    <telerik:RadPanelItemBinding  Depth="0" Expanded="true" />
                </DataBindings>
            </telerik:RadPanelBar>

            <asp:SiteMapDataSource runat="server"  ID="SiteMapDataSource1" ShowStartingNode="false"></asp:SiteMapDataSource>

In code Behind

protected void RadPanelBar1_ItemDataBound(object sender, RadPanelBarEventArgs e)
    {
        System.Web.SiteMapNode row = (System.Web.SiteMapNode)e.Item.DataItem;
     
        string url_menu = row.Url.Replace(".aspx", "").ToLower();


        if (!string.IsNullOrEmpty(row.Url) && Request.Url.AbsoluteUri.ToLower().Contains(url_menu))
        {
            e.Item.Selected = true;

            e.Item.ExpandParentItems();

        }


    }

The sitemap

<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >

<siteMapNode title="All">
<siteMapNode title="APP">
<siteMapNode title="Historical" url="~/webpages/HistoricalAppMobileSender.aspx" />
<siteMapNode title="Message" url="~/webpages/AppMobileSender.aspx" />
<siteMapNode title="Agenda" url="~/webpages/Scheduler.aspx" />
</siteMapNode>

</siteMap>

Is it possible to load spreadsheet content from an XLS file stored as a BLOB in Azure Storage?

I've gone through the exercise of embedding an XLS file directly in my ASP.NET application

by using an example found here.

  RadSpreadsheet1.Provider = new SpreadsheetDocumentProvider(Server.MapPath("~/App_Data/semda.xlsx"));

Also note that I have uploaded the XLS file using the CloudUpload control, works great!

Now I need to figure out how to make the data connection.
