Add Hidden Fields to OrgChart Node/Group Item

Hi,

I have created an OrgChart and added a rendered field using RadOrgChart.RenderedFields.ItemFields.Add().

Is there a suitable way that I can add additional data to each Node/Group Item in the OrgChart without displaying it to the user and be able to access it from the client-side? Could this be done through a hidden field or through additional rendered fields?

Thanks,

Mark

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

We are getting this error when the following code is added to a User Control:

    
            <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">  
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="JawbCategoryComboBox">  
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="JawbOccupationComboBox" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManagerProxy>

It is the <telerik:AjaxUpdatedControl> line that is causing the issue. If I comment it out, the error goes away. I read the other posts about code within the <head> tags, but the only code in the <head> section is stylesheet code. There aren't any <% %> tags anywhere in the <head> section of the master page or any of the children. Here is the exact error:

[HttpException (0x80004005): The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).]
   System.Web.UI.ControlCollection.AddAt(Int32 index, Control child) +8669270
   Telerik.Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated) +132

[HttpException (0x80004005): Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error.]
   Telerik.Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated) +180

   System.Web.UI.Control.RenderControl(HtmlTextWriter writer) +25
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1266

What else causes this error?

Thanks,
Bill

RadToolTip(Manager) on RadGrid column header

I have RadGrid with many custom filters and I want to use RadToolTip(Manager) to show tooltip window with information of applied filter on column with filter. Tooltip can be closed by user manually and then I programmatically remove filter. I have been trying unsuccessfully for three hours to attach RadToolTip to column header because that element does not have either server or client ID. How to open programmatically RadToolTip over column name?

Sitemap Column Question

I have been looking for a bit, and have not found the answer. I feel like I just might have overlooked it.

How does the RadSiteMap control know where to break the items into the next column. I am using one of your demos (loading it with XML from code behind - which doesn't work straight out of the ZIP btw). The menu item is set up with a RadSiteMap control with three columns. I can add and remove items from each of the groups, and it will continue to break in the same place. There are two groups under the first column, and one group under each of the others. How does it know, or - more importantly - how do I tell it when to break to another column?

validation and editFormColumnIndex

Is it possible to use ColumnValidation and EditFormIndexColumnIndex index together?

I have a grid where the validation was working as expected. Added editformcolumnindex and now it cannot "find" those columns.

Example following works fine without EditFormIndexColumnIndex

<telerik:GridDropDownColumn DataField="itemManager" UniqueName="editManager" HeaderText="Manager"

DataSourceID="sqlDataSource6" ListValueField="adId" ListTextField="adName" EditFormColumnIndex="2"

EnableEmptyListItem="true" EmptyListItemText="Select" DropDownControlType="RadComboBox">

<ColumnValidationSettings EnableRequiredFieldValidation="true" EnableModelErrorMessageValidation="true">

<RequiredFieldValidator ForeColor="Red" ErrorMessage=" Required Field"></RequiredFieldValidator>

<ModelErrorMessage BackColor="Red" />

</ColumnValidationSettings>

</telerik:GridDropDownColumn>

Resources manually

Hi

I bind Appointments manually with resources, but i can't see the added appointment in radscheudler.

RadScheduler1.Resources.Clear();
RadScheduler1.ResourceTypes.Clear();
ResourceType UserName = new ResourceType("User");
UserName.ForeignKeyField = "TEILNEHMERID";
UserName.KeyField = "TEILNEHMERID";
UserName.TextField = "NACHNAME";
UserName.DataSource = dsTLNINGRP_VIEW.Tables[0].DefaultView;
RadScheduler1.ResourceTypes.Add(UserName);
RadScheduler1.GroupBy = "User";
//RadScheduler1.GroupingDirection = GroupingDirection.Vertical;
RadScheduler1.DataSource = ds.Tables[0].DefaultView;
bindHolidays(dsTLNINGRP_VIEW);
RadScheduler1.DataBind();

Here is the bindHolidays Method

…

Appointment appointment = new Appointment();
appointment.ID = ds.Tables[0].Rows[i]["TEILNEHMERID"].ToString();
appointment.Subject = WAMResource.Abwesend;
appointment.Attributes["TYP"] = "A"; //Abwesend Custom Attributes
appointment.Attributes["BACKCOLOR"] = Color.Red.ToString();
appointment.BackColor = Color.Red;
appointment.Resources.Add(new Telerik.Web.UI.Resource("User", ds.Tables[0].Rows[i]["TEILNEHMERID"].ToString(), "Toprak"));
appointment.Start = DateTime.Parse(ds.Tables[0].Rows[i]["STARTTIME"].ToString());
appointment.End = DateTime.Parse(ds.Tables[0].Rows[i]["ENDTIME"].ToString());
RadScheduler1.InsertAppointment(appointment);
