Hightlight today's date for all calenders in the solution

Hello,

First of all, I'm familiair with the following solution tot hightlight today's date in a calender:

<Calendar ID="Calendar1" runat="server">

<SpecialDays>

<telerik:RadCalendarDay Repeatable="Today" ItemStyle-BackColor="Green">

</telerik:RadCalendarDay>

</SpecialDays>

</Calendar>

However, one of the new demands in my solution is to highlight all calenders in the solution. Is there any way of doing this on solution level so that i have to set this up only once?

Regards

Calendar

Sorting a column with a graphical image doesn't fire an Ajax request

Hi,

Let's consider the following markup:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" DefaultLoadingPanelID="RadAjaxLoadingPanel1">

<ClientEvents OnRequestStart="requestStart" />

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadGrid1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadGrid1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<div>

<telerik:RadGrid ID="RadGrid1" runat="server" AllowSorting="True" AutoGenerateColumns="False" GridLines="None"

OnNeedDataSource="RadGrid1_NeedDataSource" OnSortCommand="RadGrid1_SortCommand">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" SortExpression="Name" UniqueName="colTextual" />

<telerik:GridBoundColumn DataField="Name" HeaderImageUrl="Images/someImage.gif" SortExpression="Name"

UniqueName="colGraphical" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

</div>

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Default">

</telerik:RadAjaxLoadingPanel>

<telerik:RadCodeBlock ID="codeBlock1" runat="server">

<script type="text/javascript">

function requestStart(sender, eventArgs) {

alert("requestStart");

}

</script>

</telerik:RadCodeBlock>

And a bit of code-behind:

protected void RadGrid1_SortCommand(object source, Telerik.Web.UI.GridSortCommandEventArgs e)

{

RadAjaxManager m = RadAjaxManager.GetCurrent(Page);

bool inAjax = m == null ? false : m.IsAjaxRequest;

}

The grid has two columns. The only difference between them is that one of them has a textual header, the other one - a graphical header. But the columns, when clicked to sort, behave differently:
- the textual one (colTextual): on the client side calls the requestStart handler (displays the alert); on the server side the Ajax manager reports being inside an Ajax request (isAjax == true)
- the graphical column (colGraphical): doesn't call the client side handler; the Ajax manager reports that it is not inside an Ajax request (isAjax == false)

The interesting thing is that the loading panel is displayed in both cases.

What should I do to make colGraphical column to behave in the same way as colTextual?

Regards
Tomasz

Select Multiple Dates (More Than One Week)

When the RadScheduler is in MonthView, I want to be able to highlight multiple days that span more than one week. We have implemented a custom context menu when the user right-clicks in the highlighted area, that adds an all-day appointment for each day in the highlighted range once they have selected an option. The problem is we can only highlight a week at a time (on the same row) to get this to work. Once we span multiple rows, the date range does not work.

Is there some property that lets us achieve this?

function OnClientTimeSlotClick(sender, eventArgs) {

if (!sender.get_readOnly()) {

var startTime = sender._rowSelectionState.rowSelectionStartSlot._startTime;

var endTime = sender._rowSelectionState.rowSelectionEndSlot._startTime;

var dateStart = window.document.getElementById("<%= DateStart.ClientID %>");

var dateEnd = window.document.getElementById("<%= DateEnd.ClientID %>");

dateStart.value = startTime.toDateString();

dateEnd.value = endTime.toDateString();

}

Protected Sub RadScheduler_TimeSlotContextMenuItemClicking(ByVal sender As Object, ByVal e As TimeSlotContextMenuItemClickingEventArgs)

Dim scheduler As RadScheduler = DirectCast(sender, RadScheduler)

Dim MyDateStart As Date

Dim MyDateEnd As Date

If Me.DateStart.Value <> "" Then

'date range set

MyDateStart = CDate(Me.DateStart.Value)

MyDateEnd = CDate(Me.DateEnd.Value).AddDays(1)

If Not ((e.TimeSlot.Start >= MyDateStart) And (e.TimeSlot.End <= MyDateEnd)) Then

'single cell is NOT within highlighted range; reset dates

MyDateStart = e.TimeSlot.Start

MyDateEnd = e.TimeSlot.End

End If

Else

'date range NOT set

MyDateStart = e.TimeSlot.Start

MyDateEnd = e.TimeSlot.End

End If

For Each appt As Appointment In scheduler.Appointments.GetAppointmentsInRange(MyDateStart, MyDateEnd)

'delete appointment(s)

Appointments.Remove(FindById(appt.ID))

Next

AddAppointment(scheduler, MyDateStart, MyDateEnd, e.MenuItem.Text, e.MenuItem.Value)

End Sub

VS Not Displaying Telerik Controls

1st problem: Probably a simply problem, the page runs fine but the ASP.NET Radcontrols don't display in the Designer - see attached screen capture - "Error Rendering Control - button" - in the Bin\ folder are: Telerik.Web.UI.dll, Telerik.Web.UI.Skins.dll and Telerik.Web.UI.xml. Again, it runs fine.

2nd problem: I can't drag any ASP.NET Radcontrol to the Designer, the control doesn't get placed on to the page. I CAN drag any Standard control (i.e. button, textbox, etc...) which works fine, but not Telerik controls. I've been typing them in the Source, but it'd be really nice to drag them too.

Thank you in advance!

Kind regards,
Derek

GridButtonColumn, CommandArgument and GetDataKeyValue

Hi,

I have a grid with two GridButtonColumn columns. In the ItemCommand event handler I want to extract the key value of the clicked row. First, I've used the following technique:

var keyValue = (e.Item as GridDataItem).GetDataKeyValue("keyField"));

It worked with one of the columns but soon I've found out that it doesn't work with the other one. In this case it always extract the key value from the very first row. So I've used another technique (directly from your documentation):

GridDataItem item = MyGrid.Items[int.Parse(e.CommandArgument)];

var keyValue = item.GetDataKeyValue("keyField");

This technique works with the second column but - surprise, surprise :-) - it doesn't work with the first one (where e.CommandArgument is always empty).

OK, I can deal with it (when e.CommandArgument is empty use one technique, when not empty - another) but I'm curious, what is the rule. I don't set the CommandArgument value explicitly - in any case. The columns are not designed identically but the differences seem to be not vital:

CommandName standard (RadGrid.DeleteCommandName) / non-standard
ImageUrl declared / declared but further adjusted dynamically (ItemDataBound, ImageButton control found, its ImageUrl attribute adjusted)
not sortable / sortable

The worst is that I've tried to reproduce all that stuff in a test application but I've failed (only the first technique worked - e.CommandArgument was always empty).

Can the authors of RadGrid check, when they set CommandArgument to the index in the Items collection and when - not?

GUID Not Being Passed to Detail Table

I have been attempting to get a detail table working connecting through a LINQ data source in a Grid. When I attempt to expand the detail table, the ID for the SelectParameter is being passed through as null. Does anyone know why this might be happening?

ASPX code:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="rgFacilities">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgFacilities" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadGrid DataSourceID="ldsFacilities" AutoGenerateColumns="false" AllowPaging="True" PageSize="20" AllowSorting="True" ID="rgFacilities" runat="server">

<MasterTableView DataKeyNames="FacilityID" DataSourceID="ldsFacilities" AllowMultiColumnSorting="False" GroupLoadMode="Server">

<DetailTables>

<telerik:GridTableView DataKeyNames="EquipmentID" DataSourceID="ldsEquipment" Width="100%"

runat="server" AutoGenerateColumns="true">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="FacilityID" MasterKeyField="FacilityID" />

</ParentTableRelation>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="Name" HeaderText="Facility Name"

DataField="Name" UniqueName="Name">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="City" HeaderText="City"

DataField="City" UniqueName="City">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="Region" HeaderText="State/Province"

DataField="Region" UniqueName="Region">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="Country" HeaderText="Country"

DataField="Country" UniqueName="Country">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn SortExpression="Description" HeaderText="Description"

DataField="Description" UniqueName="Description" AllowSorting="false">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:LinqDataSource ID="ldsFacilities" OnSelecting="ldsFacilities_Selecting" runat="server">

</asp:LinqDataSource>

<asp:LinqDataSource ID="ldsEquipment" OnSelecting="ldsEquipment_Selecting" runat="server">

<SelectParameters>

<asp:SessionParameter Name="FacilityID" SessionField="FacilityID"/>

</SelectParameters>

</asp:LinqDataSource>

Data Source Selecting Code:

protected void ldsFacilities_Selecting(object sender, LinqDataSourceSelectEventArgs e)

{

Data.EcofitDataContext db = new Data.EcofitDataContext();

e.Result = (from f in db.Facilities

select f);

}

protected void ldsEquipment_Selecting(object sender, LinqDataSourceSelectEventArgs e)

{

Data.EcofitDataContext db = new Data.EcofitDataContext();

e.Result = (from eq in db.Equipments

where eq.FacilityID == Guid.Parse(e.SelectParameters["FacilityID"].ToString())

select eq);

}

Any help would be greatly appreciated!
