Non HTML5 compatible browser support

HI Telerik

Is it possible to play video files using radmediaplayer in browsers that are not HTML5 compatible? Like the control can make use of flash plug-ins installed on the browser to play videos if it does not support HTML5.

RadDatePicker Calendar Month/Year Changed Server-Side Event

Hi all,

I am currently using the OnDayRender event of the Calendar of my RadDatePicker which executes normally but, on a number of times only. My objective is to disable dates which are already taken and enable only Sundays for selection. So here's my code:

protected void Calendar_OnDayRender(object sender, Telerik.Web.UI.Calendar.DayRenderEventArgs e)

{

// disable all days except Sunday

if (e.Day.Date.DayOfWeek != DayOfWeek.Sunday)

{

CalendarDatesDisabler(sender, e);

}

// for Sundays, disable the dates already taken in the records

// if no records with this date do not disable

else // if (e.Day.Date.DayOfWeek == DayOfWeek.Sunday)

{

if (_dtForCalendarDayRender.Rows.Count > 0)

{

if (_dtForCalendarDayRender.Select(string.Format("startdate = '{0:MM/dd/yyyy}'", e.Day.Date)).Length == 0)

return;

CalendarDatesDisabler(sender, e);

}

The above block of code runs just what it is expected to do, but it seems to trigger only for 30 number of days, maybe, after that it stops executing and then leaving other Sundays as enabled where it should not be. What can you suggest with this? I have searched the web with the server-side event of on month/year changed so that each time the month or year is selected it will disable the specific calendar days but found nothing.

Thanks for your response!

RADAjaxLoadingPanel + Addthis won't show on Chrome and Safari

Hi,

Can you help us with our problem on safari and chrome? The ajax loading panel will only show once and after that it will not show up anymore. I tried to debug this found out that after a successful ajax on first try, it displays a javascript error on console.

TypeError: 'null' is not an object (evaluating 'f.cssRules.length').

I tried to debug and found out that the f variable was the addthis css ("http://ct1.addthis.com/static/r07/counter014.css")

Thanks,

JP

Grid not ignoring Paging on Export

Never had a problem with this until now and I think it is some extra code I need with C#, just switched over last month and its always worked with VB. BUt my grid will not ignore paging on export, it only exports the current page. Is there some extra code behind I need. I put in the GridExporting and BiffExporting but niether made a difference still only 1 page that gets exported. So what am I missing?

<telerik:RadGrid ID="myRadGrid" runat="server" Skin="Web20" Width="80%" OnNeedDataSource="myRadGrid_NeedDataSource" CssClass="CentDiv3" OnPageIndexChanged="myRadGrid_PageIndexChanged"

OnPageSizeChanged="myRadGrid_PageSizeChanged" OnSortCommand="myRadGrid_SortCommand" OnGridExporting="myRadGrid_GridExporting" OnBiffExporting="myRadGrid_BiffExporting">

<ExportSettings ExportOnlyData="true" Excel-Format="Biff" IgnorePaging="true" OpenInNewWindow="true"></ExportSettings>

<MasterTableView runat="server" AutoGenerateColumns="false" Font-Size="9" AllowPaging="true" AllowSorting="true" CommandItemDisplay="Top">

protected void myRadGrid_PageIndexChanged(object sender, GridPageChangedEventArgs e)

{

fillGrid = true;

myRadGrid.Rebind();

}

protected void myRadGrid_PageSizeChanged(object sender, GridPageSizeChangedEventArgs e)

{

fillGrid = true;

myRadGrid.Rebind();

}

protected void myRadGrid_SortCommand(object sender, GridSortCommandEventArgs e)

{

fillGrid = true;

myRadGrid.Rebind();

}

protected void myRadGrid_GridExporting(object sender, GridExportingArgs e)

{

fillGrid = true;

myRadGrid.Rebind();

}

protected void myRadGrid_BiffExporting(object sender, GridBiffExportingEventArgs e)

{

fillGrid = true;

myRadGrid.Rebind();

}

Hide Add new record command item

I found the tutorial that talked about hiding the default command items, but I don't think it showed how to do it. When I use the CommandItemSettings tag I only find the Show command for the four export types and not the Add new or Refresh item. How can I hide the "Add new record" command item?

Sorry if this is an elementary issue. I can't figure out how to do it....

Heirarchy table alignment

I have a Radgrid that has a MasterTable and a DetailsTable. They basically have the same columns, the Master is top level view and the details is broken down data. However, when I export the data to Excel the columns are no longer aligned. How can I get them to align?

Thank You in advance!

Dropdown has so items until after postback

I have a DropDownList (have also tried ComboBox with the same results) that gets populated during page_load if it's not a post back. The code executes fine and the DropDownListItems are created and appear to be added from the code behind but when the page renders the DropDownList is empty/disabled. As soon as I do a post back (checkbox click), when it reloads, all of my DropDownLists now actually show the data and can be clicked on.

I've isolated this down to being caused when I load data into the DropDownList during page_load. On the post back, the data loading doesn't occur (as expected) and allows the items loaded from the initial page_load to be displayed.

Any ideas why this happens or what I can do to fix it? I've searched and searched but haven't found a solution that works. The ComboBox exhibits the exact same behavior.

Relevant code:

DropDownList markup:

<telerik:RadDropDownList ID="cmbPayment_CardType" runat="server"

OnSelectedIndexChanged="cmbPayment_CardType_SelectedIndexChanged"

Width="160px" DropDownHeight="90px" DropDownWidth="160px" />

page_load from code behind:

protected void Page_Load(object sender, EventArgs e)

{

try

{

if (!IsPostBack)

{

List<CreditCardListItem> lstCreditCards = null;

//Load the list of accepted credit cards

cmbPayment_CardType.Items.Clear();

lstCreditCards = GetCreditCardsList();

if ((lstCreditCards != null) && (lstCreditCards.Count > 0))

{

foreach (CreditCardListItem ccDetails in lstCreditCards)

cmbPayment_CardType.Items.Add(new DropDownListItem() { Text = ccDetails.DisplayName, Value = ccDetails.DisplayOrder.ToString() });

}

lstCreditCards.Clear();

}

catch (Exception ex)

{

System.Diagnostics.Debug.Print("Error: " + ex.ToString());

}
