I have a radPanelBar that is is bound to an SqlDataSource. Normally I would use findcontrol in the OnItemDataBound event to access the controls in the template as follows:

Private Sub rpbVehicles_ItemDataBound(sender As Object, e As RadPanelBarEventArgs) Handles rpbVehicles.ItemDataBound

Dim imgThumb As Image = e.Item.FindControl("imgThumb")

End Sub

But apparently ItemDataBound is too early in the cycle to access controls as findcontrol always returns Nothing.

I can access the controls in the ItemCreated event, but how do I access the DataItems there?

I want to do something like:

Private Sub rpbVehicles_ItemCreated(sender As Object, e As RadPanelBarEventArgs) Handles rpbVehicles.ItemCreated

Dim vehicleID As Integer = e.Item.DataItem("ItemID")

Dim cbShow As CheckBox = e.Item.FindControl("cbShow")

cbShow.Attributes.Add("VehicleID", vehicleID.ToString)

End Sub

How do I access the DataItems?

Thanks

Confirmation message for the AutoGenerate delete button

Hi,

I have an AutoGenerate delete link in my aspx page.

AutoGenerateDeleteColumn="True"

Currently, when the use clicks on the delete button, the record is deleted without any warning or confirmation. How can I ask the user if they are sure of the deleting the record or not? After confirmation only the record should be deleted. I am currently deleting the records from the DeleteCommand event in the code behind.

I saw a thread about the same issue, but I am not able to understand, how can I set the ConfirmText property for the AutoGenerateDeleteColumn. Can anyone help me with addition of this feature without requiring to change my current set up. Thanks..

AppointmentsPopulating fails to fire

Hi there,

I am trying to implement getting data for the Scheduler (Q1 2014) via a Web Service.

I have followed the instructions and created a new class derived from SchedulerInfo.

My aspx contains the following: <telerik:RadScheduler ID="RadScheduler1" runat="server" OnAppointmentsPopulating="RadScheduler1_AppointmentsPopulating" OnResourcesPopulating="RadScheduler1_ResourcesPopulating">
<WebServiceSettings Path="SchedulerWebService.asmx" ResourcePopulationMode="ServerSide" />

</telerik:RadScheduler>

I can add custom values to this in the server side code using

protected void RadScheduler1_ResourcesPopulating(object sender, Telerik.Web.UI.ResourcesPopulatingEventArgs e)

so I seem to be on the right course.

However, when I try to do the same for the AppointmentsPopulating event, this is never fired.

Have I done something obviously wrong?

RadTextBox emptyMessage is still there on focussing

Hi,

I set a textbox to be focussed from server side inside the IsPostBack event as txtUserName.Focus(). Once the page gets rendered completely my focus is retained in that control but the empty mesage in that textbox is still there. My empty message is still there as normal text so once if i start typing the text also the empty message is still there like this,
If my empty message is like "Enter user name" and if i start typing it is like "adminEnter user name".

Rest of the textbox in the page is working as per functionality but only if i set focus to a textbox that textbox alone looses the style,,,

Client API: read values inside a radNumerictextBox

Hi

I have a radGrid with template columns.

Inside one of them, there is radNumericTextBox which fire the client events onValueChanged, that go through each row to make some calculation.

I'd like to make everything client-side without any postback, but I'm not able to access the value of the radNumericTextBox.

Is there a way to do this?

Here is the code:

<telerik:RadGrid ID="GrdCartList" runat="server" AutoGenerateColumns="false" OnNeedDataSource="GrdCartList_NeedDataSource" Skin="Bootstrap">

<MasterTableView DataKeyNames="ProductId">

<Columns>

<telerik:GridTemplateColumn DataField="ProductId" FilterControlAltText="Filter ProductId column" FilterControlWidth="100px"

HeaderText="Id" UniqueName="ProductId" SortExpression="ProductId" AutoPostBackOnFilter="true">

<ItemTemplate>

#<%# Eval("ProductId") %>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="ProductName" FilterControlAltText="Filter ProductName column" FilterControlWidth="350px"

HeaderText="Prodotto" UniqueName="ProductName" SortExpression="ProductName" AutoPostBackOnFilter="true">

<ItemTemplate>

<%# Eval("BrandName") %> - <%# Eval("ProductName") %>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="ProductSellPrice" FilterControlAltText="Filter ProductSellPrice column" FilterControlWidth="150px"

HeaderText="Prezzo" UniqueName="ProductSellPrice" SortExpression="ProductSellPrice" AutoPostBackOnFilter="true">

<ItemTemplate>

<%# Eval("ProductSellPrice") %>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="ScProductQuantity" FilterControlAltText="Filter ScProductQuantity column" FilterControlWidth="150px"

HeaderText="Quantita'" UniqueName="ScProductQuantity" SortExpression="ScProductQuantity" AutoPostBackOnFilter="true">

<ItemTemplate>

<telerik:RadNumericTextBox ID="TxtQuantity" runat="server" Value='<%# Convert.ToInt32(Eval("ScProductQuantity")) %>' NumberFormat-DecimalDigits="0"

Type="Number" MinValue="1" ShowSpinButtons="true" >

<ClientEvents OnValueChanged="onClientValueChanged" />

</telerik:RadNumericTextBox>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

<script type="text/javascript">

function onClientValueChanged(sender, args) {

calculateCart();

}

function calculateCart() {

var grid = $find("<%=GrdCartList.ClientID %>");

var masterTableView = grid.get_masterTableView();

var selectedRows = masterTableView.get_dataItems();

var total = 0;

for (var i = 0; i < selectedRows.length; i++) {

var row = selectedRows[i];

var cellPrice = masterTableView.getCellByColumnUniqueName(row, "ProductSellPrice")

var cellQty = masterTableView.getCellByColumnUniqueName(row, "ScProductQuantity")

alert(cellQty.innerHTML);

// total += (cellPrice.innerHTML * cellQty.innerHTML);

}

</script>

Radscheduler Row Height Issues

Hi I am having some difficulties after setting the Row height for the radscheduler to something other than the default.

It seems that after the row height is changed the end time of the actual appointment block created no longer matched what was set via the editor. i.e. I create an appoint from 12:00 - 15:00 and the scheduler will show the appointment running from 12:00 - 13:00.

I also noticed the same happens in the Scheduler demo (Scheduler - Day, Week and Multi-day Views) Is there any fix for this?

e.Container.FindControl("RecurrentAppointment") returns "Nothing"

Hi,

i implemented an .aspx page, with a RadScheduler.

1. <telerik:RadScheduler ID="RadScheduler1" runat="server" Culture="Italian (Italy)" ProviderName="AllotmentSchedulerData" SelectedView="TimelineView" DayEndTime="08:00:00" AdvancedForm-EnableCustomAttributeEditing="True" CustomAttributeNames="Contingente Camere,Release,Attivo,explode" RowHeight="55px" FirstDayOfWeek="Monday" LastDayOfWeek="Sunday" ShowHoursColumn="False" WorkDayEndTime="08:00:00" OverflowBehavior="Expand" Style="top: 0px; left: 0px" MonthHeaderDateFormat="MMMM, yyyy" StartInsertingInAdvancedForm="True" >

<AppointmentTemplate>

<asp:Label runat="server" ID="RecurrenceIcon" />

<%# Eval("Subject") %>

<asp:Label runat="server" ID="TCpL" />

<asp:Label runat="server" ID="TCL" />

</AppointmentTemplate>

<MonthView VisibleAppointmentsPerDay="5" HeaderDateFormat="MMMM, yyyy" />

<TimelineView HeaderDateFormat="dd/MM/yyyy" NumberOfSlots="25" SlotDuration="1.00:00:00" ColumnHeaderDateFormat="dd/MM" ShowInsertArea="true" GroupBy="roomType" GroupingDirection="Vertical" /><DayView DayEndTime="08:00:00" ShowHoursColumn="False" WorkDayEndTime="08:00:00" UserSelectable="False" /><WeekView UserSelectable="False"/>

</telerik:RadScheduler>

...and this is the code behind

1. Private Sub RadScheduler1_FormCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.SchedulerFormCreatedEventArgs) Handles RadScheduler1.FormCreated ............. Dim chk2 As CheckBox = e.Container.FindControl("AllDayEvent")  Dim chk1 As CheckBox = e.Container.FindControl("RecurrentAppointment")  Dim chk3 As RadTimePicker = e.Container.FindControl("StartTime")  Dim chk4 As RadTimePicker = e.Container.FindControl("EndTime")  CType(e.Container.FindControl("AllDayEvent"), CheckBox).Style.Add(HtmlTextWriterStyle.Visibility, "hidden")  CType(e.Container.FindControl("RecurrentAppointment"), CheckBox).Style.Add(HtmlTextWriterStyle.Visibility, "hidden")  CType(e.Container.FindControl("StartTime"), RadTimePicker).Style.Add(HtmlTextWriterStyle.Visibility, "none")  CType(e.Container.FindControl("EndTime"), RadTimePicker).Style.Add(HtmlTextWriterStyle.Visibility, "none")...............End Sub

the code "CType(e.Container.FindControl("RecurrentAppointment"), CheckBox).Style.Add(HtmlTextWriterStyle.Visibility, "hidden")" returns me an error, in the ScriptResource.axd file (Object reference not set to an instance of an object)

the variable chk1 is "Nothing".

Any idea how to solve the issue?

Thanks in advance
