why I got error: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>). for RadAjaxManager

hi,

I have RadTimePicker, and i need to forbid posting back when time is picked, so I have decided to use RadAjaxManager, now when I have use it and select time picker to update it self, I got this error in my other jquery/ javascript when I am getting ID of server controls client id:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

so what do I do to take out this error? or how do I prevent post back for time picker when time is selected?

OnClientAppointmentInserting incorrect timeslot

Hi,

I am trying to get the selected time range for a new appointment and am getting incorrect information passed into the OnClientAppointmentInserting method. As shown in the screen shot "appointment selection.jpg" I select a time period of 10:30 am to 12:30 pm, I then right click and select new appointment. When the OnClientAppointmentInserting method is fired the start time is now 12:00 pm and the end time is now 12:15 pm (see "timeslot.jpg").

Am I missing something or is this an issue with the OnClientAppointmentInserting event?

Thanks

Gavin.

Here is my code

<telerik:RadScheduler ID="rsAppointments" runat="server"

DataEndField="AppointmentEndDate"

DataKeyField="PatientAppointmentID"

DataStartField="AppointmentStartDate"

DataSubjectField="AppointmentTypeID"

DataDescriptionField="AppointmentTypeID"

Height="600px" MinutesPerRow="15"

onnavigationcomplete="rsAppointments_NavigationComplete"

OnClientAppointmentInserting="OnInsertAppointment"

OnClientAppointmentEditing="OnEditAppointment"

GroupBy="Clinicians"

onappointmentcreated="rsAppointments_AppointmentCreated"

onappointmentupdate="rsAppointments_AppointmentUpdate"

onappointmentdelete="rsAppointments_AppointmentDelete">

<TimelineView UserSelectable="False" />

<ResourceTypes>

<telerik:ResourceType Name="Clinicians" KeyField="UserID" TextField="ClinicianName" ForeignKeyField="ClinicianID" />

</ResourceTypes>

<AppointmentTemplate>

<table border="0" cellpadding="3" cellspacing="0" width="100%">

<tr>

<td style="border: none;" rowspan="2"><asp:Literal ID="litContent" runat="server"></asp:Literal></td>

</tr>

</table>

</AppointmentTemplate>

<AppointmentContextMenuSettings EnableDefault="true" />

<TimeSlotContextMenuSettings EnableDefault="true" />

</telerik:RadScheduler>

function OnInsertAppointment(sender, args)

{

var slot = args.get_targetSlot();

var dteStart = slot.get_startTime();

var dteEnd = slot.get_endTime();

var res = slot.get_resource();

var resourceID = res.get_key();

var oManager = GetRadWindowManager();

var oWnd = oManager.getWindowByName("rwAppointment");

var URL = "AppointmentEdit.aspx?mode=insert&start=" + dteStart.toString("dd/MM/yyyy HH:mm:ss tt") +

"&end=" + dteEnd.toString("dd/MM/yyyy HH:mm:ss tt") +

"&cID=" + resourceID +

"&pid=" + <%= PatientID %>;

oWnd.setUrl(URL);

oWnd.show();

args.set_cancel(true);

}

Telerik RadScheduler AdvancedForm At Insert/Update

Hello,

Within the AppointmentInsert or AppointmentUpdate event handler, how can I get ASP.NET control references from an advanced form edit/insert template? I need to find an ASP.NET control in the template within these two events only, and use its value for save.

Thanks.

Argument Null Exception when using AddAjaxSetting

Hello,

I am working on an ASP.Net page (using VB) that dynamically builds a table and form. When the page loads and it's building the form and table there are a series of controls that I'm trying to create and add to an Ajax Manager (that is also created in code) but when I'm trying to do an AjaxManager.AjaxSettings.AddAjaxSetting(oCheckbox, oRadTextBox) I get an error:

ArgumentNullException was unhandled by user code.
Value cannot be null.
Parameter name: page

I was doing some research into the problem and found this post:
http://www.telerik.com/community/forums/aspnet-ajax/ajax/problem-when-using-radajaxmanager-in-umbraco.aspx

At the end of the post Maria Ilieva was following up with the original poster and said something about MasterPages and how the ajax manager is placed. I'm using master pages so I suspect that's my problem. The master page is very simple and has nothing more than formatting, style statements, logos, etc. The web form that uses the master page is where the ajax manager resides. I've paraphrased a stripped down simple version of the code here so you can see what I'm doing. I'm creating two controls, adding them to cells to a row and table then trying to add them to the ajax manager.

oCheckbox.ID = "chk1"

oCheckbox.AutoPostBack = True

oCell.Controls.Add(oCheckbox)

oRow.Cells.Add(oCell)

oRadTextBox.ID = "txtSerial"

oCell.Controls.Add(oRadTextBox)

oRow.Cells.Add(oCell)

oTable.Rows.Add(oRow)

oAjaxManager.AjaxSettings.AddAjaxSetting(oCheckbox, oRadTextBox)

The ArumentNullException error occurs on the last statement with the AddAjaxSetting method. How am I supposed to be calling this from the web form when using master pages?

Empty Column & Row

Grid is displaying an empty column and row. I have tried setting the width of the grid to exactly the width of the column widths combined, however, this results in a horizontal scroll which is not desired unless the columns get resized. In addition, even when I made the grid exactly the size of the column widths combined the empty column and row still appeared. The only column sizing I do in the C# code behind is to set the filter text box size (which is 25px less than the column width).

protected void RadGridAggressiveMatches_ItemCreated(object sender, GridItemEventArgs e)

{

if (e.Item is GridFilteringItem)

{

GridFilteringItem filteringItem = e.Item as GridFilteringItem;

//set dimensions for the filter textbox
TextBox box = filteringItem["Column1"].Controls[0] as TextBox;
box.Width = Unit.Pixel(50);

box = filteringItem["Column2"].Controls[0] as TextBox;

box.Width = Unit.Pixel(50);

box = filteringItem["Column3"].Controls[0] as TextBox;

box.Width = Unit.Pixel(175);

box = filteringItem["Column4"].Controls[0] as TextBox;

box.Width = Unit.Pixel(175);

box = filteringItem["Column5"].Controls[0] as TextBox;

box.Width = Unit.Pixel(175);

box = filteringItem["Column6"].Controls[0] as TextBox;

box.Width = Unit.Pixel(175);

box = filteringItem["Column7"].Controls[0] as TextBox;

box.Width = Unit.Pixel(15);

box = filteringItem["Column8"].Controls[0] as TextBox;

box.Width = Unit.Pixel(45);

}
