Order by Resource items

I am trying to get my scheduler entries to show up in order of a resource (called PeriodID). The resource is used to store the ID of the Period selected (from the Period Table) as follows:

On Call (ID=1)
AM (ID=2)
PM (ID=3)
All Day (ID=4)

I am using SQL Datasources for binding.

I have tried using Order By PeriodID in the Datasource Select statement for the Schedule Data but that doesn't work. I then tried creating a class and using the appointmentcomparer as shown here http://www.telerik.com/community/forums/aspnet-ajax/scheduler/oder-of-entry-in-scheduler.aspx#1155620 but that adds another field to the Advanced form for manual PeriodID entry which is not what I need.

Does anyone know how to have the scheduler order entries by Resource? Thanks.

Populating Recurrence Editor?

I'm having difficulty getting the RecurrenceEditor to populate from existing values.

Here's Telerik's example on how to populate the control:
http://www.telerik.com/help/aspnet-ajax/recurrenceeditor_serverside_populating.html

I created some code to read my selection and it spits out:



Recurrence Rule Text:

DTSTART:20101124T173647Z DTEND:20000102T000000Z RRULE:FREQ=DAILY;UNTIL=20101130T000000Z;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR

Scheduled Dates

11/24/2010 5:36:47 PM

11/25/2010 5:36:47 PM

11/26/2010 5:36:47 PM

11/29/2010 5:36:47 PM

The control's state renders fine between post backs. I then store the Recurrence Recurrence Rule Text in my database but when I try to read it back to the control later on I get nothing. None of the items are selected in the control and even the Recurrence Checkbox isn't selected? So, how do I assign this control it's values? Here's my assignment code:



protected

void Page_Load(object sender, EventArgs e)

{

this.RecurrenceEditor1.StartDate = Convert.ToDateTime("11/24/2010 5:36:47 PM");

this.RecurrenceEditor1.RecurrenceRuleText =

"DTSTART:20101124T173647Z DTEND:20000102T000000Z RRULE:FREQ=DAILY;UNTIL=20101130T000000Z;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR"

;

}

Any help would be appreciated,

Thanks,

Scheduler

Show Hide RadComboBox depending on RadioButtonList Selected Value

Folks,

Is it possible to show/hide RadComboBox depending on the RadioButtionListSelected Value? For example In RadioButtonList1_SelectedIndexChanged event, if my RadioButtonList1's selected Value = "1", show RadcomboBox (CountryName), else hide the RadComboBox. Both My RadioButtonList and ComboBox are within EditTemplate of RadGrid.

Below is my code.

Thanks

<telerik:GridTemplateColumn DataField="rblLIST" HeaderText="rbl" UniqueName="rBL">

<EditItemTemplate>

<asp:RadioButtonList ID="RadioButtonList1" runat="server" AutoPostBack = "true"

onselectedindexchanged="RadioButtonList1_SelectedIndexChanged"

RepeatDirection="Horizontal">

<asp:ListItem Text="Yes" Value="1"></asp:ListItem>

<asp:ListItem Text="No" Value="2"></asp:ListItem>

</asp:RadioButtonList>

</EditItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn DataField="CountryName" HeaderText="Country" UniqueName="CountryName">

<ItemTemplate>

<asp:Label ID="Label3" runat="server" Text='<%# Eval("CountryName") %>'></asp:Label>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadComboBox ID="rcbCountries"

runat="server"

AutoPostBack="true"

Skin="Vista"

DataTextField="Name"

DataValueField="CountryID">

</telerik:RadComboBox>

AJAX: RadGrid and User Control in RadSplitter

Hi there,



I have a page with RadSplitter which contains RadGrid and my custom user control (Footer) in two separate 

RadPanes. I enabled ajax on the grid, but I would like to update the footer with ajax as well. In code 

below I have tried inserting the footer id or the id of a panel that wraps the footer as ControlID in 

AjaxUpdateControl tag. None of them worked and they even caused that the RadGrid doesn't work properly 

(when I click on the next page button, it doesn't change the page, but loading icon is shown). 

The footer user control contains only <%Reponse.Write(DateTime.Now);%>. 



What am I missing?

Adding items to the HeaderContextMenu

I have tried several attempts to add a item to the HeaderContextMenu. I was able to add a item utilizing this method

Protected Overloads Overrides Sub OnPreRenderComplete(ByVal e As EventArgs)

Dim menu As

RadContextMenu = rgvSchedules.HeaderContextMenu

Dim item As New RadMenuItem()

item.Text = "Paste Results"

item.PostBack = True

menu.Items.Add(item)

MyBase.OnPreRenderComplete(e)

End Sub

The Postback method is because I was attempting to find a way to set a server side procedure on click. I removed the excess code from my failed attempts. There inlies the problem. I cannot for the life of me find a way to set the onclick method for the item that I added and when it is clicked I get a runtime error:

Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.

Automaticaly inserted spaces to Header in programmaticaly created Grid

Hello All,
I've faced to problem, that in Q3 2010 for AJAX when I use programmatically created RadGrid, header text is changed against SQL datasource - automatically inserted spaces in string (e.g. "Order ID" instead of "OrderID", "NBREQ_ TCP" instead of "NBREQ_TCP").
Is there any way to avoid header text change in dynamic grid without static columns declaration?

This code is used to fill Grig (DGrid) with data from DataSet (dst)

dtv = dst.Tables("SourceTable").DefaultView()

dtv.Sort = sortstring

DGrid.DataSource = dtv_stat

DGrid.DataBind()

Thanks,
MexaHukyc

Issues w/ Radgrid Maskedcolumn Input

Have a grid w/ in-place editing enabled. One of the fields stores a dollar amount (unit price) which is databound to my sql database via an sqldatasource, decimal(10,2) field. The column definition is as follows:

<telerik:GridMaskedColumn DataField="UnitPrice" DisplayMask=""

HeaderText="Unit Price" Mask="$##,###.##" UniqueName="Unit Price"

DataFormatString="{0:C2}">

<HeaderStyle HorizontalAlign="Center" Width="100px" />

<ItemStyle HorizontalAlign="Center" Width="100px" />

</telerik:GridMaskedColumn>

Let's take an item with a unit price of $110.00 from the database.

When the grid initially loads, the column properly displays the amount as $110.00

If I click edit, my in-place editing form appears and the input box for the unit price appears as:

$11,0__.00

Suffice to say, this is clearly incorrect. There are other editable columns in the grid... if the user intends to edit a different field (such as description) they also have to "correct" the incorrect unit price -- each and every time they perform an edit operation -- otherwise if they attempt to update w/o correcting it, they receive a "Exception Details: System.FormatException: Input string was not in a correct format." error when trying to update. This is very annoying to the user community.

Why is the masked control displaying the data incorrectly for edit, and how can I correct it so the value is properly displayed on the edit form to avoid this issue?

Client event for when expansion animation is done

Hi All,
I have a panelbar set up in FullExpandedItem mode.
Inside one of these I have a grid that scrolls. I have found that on a callback, the grid loses it's scroll position, so I need to track that. Ok, I have that working.
My issue comes when my scrolling code is fired before the expand animation is complete - basically, once the animation is complete, the grid scroll position gets set back to the top.
I have solved it partially by choosing an arbitrary setTimeout number to make my scrolling code fire after the expand animation has finished, but I am having trouble finding out what this is meant to be!
I have an ExpandAnimation Duration of 200, 0 Delay, type OutQuart, but for some reason, I need to wait 500 ms to run my code. Why is this? If I use the Duration, it is too soon. The client event OnClientItemExpand seems to occur when the expansion starts, so is no good to me.
Is there a reliable way to find out whether the animation has completed so that my scrolling code will work without a pause and reliably?
Thanks,
Steele.
