HI

What would cause this line to return Undefined. This was working in the VB version, but I'm redoing it in C# binding to an oData webservice deserialised using NewtonSoft.json library.

function OnClientAppointmentClick(sender, eventArgs) {
var booking_id = eventArgs.get_appointment().get_attributes().getAttribute("Id");
alert(booking_id);

I have the id in the datasource and the following markin in the control.

DataKeyField="Id"
CustomAttributeNames="Id"
DataSubjectField="Descrption"
DataStartField="SlotStart"
DataEndField="SlotEnd"

OnDemand Duplicates Items on virtual scrolling

I have a RadComboBox with multiple columns of text shown, I have not found a solution to the virtual scrolling duplicating all items in the combo.

Here is the code - aspx:

<telerik:RadComboBox ID="radcmbProduct" runat="server" Width="400px" Height="200px" AllowCustomText="false"

EmptyMessage="Select a Product" EnableLoadOnDemand="True" ShowMoreResultsBox="true" DropDownWidth="600px"

EnableVirtualScrolling="true" HighlightTemplatedItems="true" MarkFirstMatch="true" ItemsPerRequest="60"

NoWrap="true" OnItemsRequested="radcmbProduct_ItemsRequested" OnItemDataBound="radcmbProduct_ItemDataBound">

<HeaderTemplate>

<ul>

<li class="col1">Title</li>

<li class="col2">System</li>

<li class="col3">Price</li>

</ul>

</HeaderTemplate>

<ItemTemplate>

<ul>

<li class="col1">

<%# DataBinder.Eval(Container.DataItem, "Title") %></li>

<li class="col2">

<%# DataBinder.Eval(Container.DataItem, "GameSystemName")%></li>

<li class="col3">

<%# DataBinder.Eval(Container.DataItem, "DisplayPrice")%></li>

</ul>

</ItemTemplate>

</telerik:RadComboBox>

and here is the code behind:

private DataSet GetProductDataSet(string productText)

{

string errorMsg = string.Empty;

DataSet DS = new DataSet();

Product.GetByName(FacilityID, productText, ref DS, ref errorMsg);

return DS;

}

protected void radcmbProduct_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

DataSet data = GetProductDataSet(e.Text);

radcmbProduct.DataSource = data;

radcmbProduct.DataBind();

}

protected void radcmbProduct_ItemDataBound(object sender, RadComboBoxItemEventArgs e)

{

e.Item.Text = ((DataRowView)e.Item.DataItem)["Title"].ToString() + " | " + ((DataRowView)e.Item.DataItem)["GameSystemName"].ToString() + " | " + ((DataRowView)e.Item.DataItem)["DisplayPrice"].ToString();

e.Item.Value = ((DataRowView)e.Item.DataItem)["ProductID"].ToString();

}

So I need to find a way to prevent the items duplicating on scrolling, while maintaining the multiple column text capability. I have tried adding radcmbProduct.Items.Clear() prior to the DataBind() in the Items Requested method, however, this had no effect.

I have tried using the attributes as suggested in a previous post however, there were issues with that where the multi-column would only populate the first column.

I have not found a working solution.

Telerik RadGrid AJAX UI Batch Edit Mode Template Column with Dropdo

I am using Telerik RadGrid for AJAX UI. The grid is being used in batch edit mode. Grid has a column which needs to display dropdown in edit mode. In telerik forums, the approach is used by using SQLDatasource. But I wish to populate the dropdown when the the cell is clicked. I guess the only way to achieve is to use the client side api. Can somebody guide me on how to achieve this.

How To Show Multiple Projects RadGanttChart?

Hi,

I'm trying to show more than one projects on a single GanttChart. I've tried using an xmlProvider an using the structure <Projects><Project><Tasks><Task>, but nothing happens. The xmlProvider throw me an exception "incorrect structure". There's any way to do that?

my code:

<telerik:RadGantt runat="server" ID="GanttChart" CssClass="GanttChart" OnDataBound="GanttChart_DataBound" Skin="Silk" ListWidth="400px" Height="450px" Width="1000px" SelectedView="WeekView" AutoGenerateColumns="false" WorkWeekStart="Monday" WorkWeekEnd="Friday" >

<Columns>

<telerik:GanttBoundColumn DataField="Title" HeaderText="Attivita" DataType="String" UniqueName="Title" Width="150px" AllowEdit="false"></telerik:GanttBoundColumn>

<telerik:GanttBoundColumn DataField="Start" HeaderText="Inizio" DataType="DateTime" UniqueName="Start" DataFormatString="dd/MM/yy" Width="65px" AllowEdit="false" />

<telerik:GanttBoundColumn DataField="End" HeaderText="Fine" DataType="DateTime" UniqueName="End" DataFormatString="dd/MM/yy" Width="65px" AllowEdit="false" />

<telerik:GanttBoundColumn DataField="PercentComplete" HeaderText="Completamento" DataType="Number" UniqueName="PercentComplete" Width="110px" AllowEdit="false" />

</Columns>

<YearView UserSelectable="true" />

<DataBindings>

<TasksDataBindings IdField="ID" ParentIdField="ParentID" StartField="Start" SummaryField="Summary" EndField="End" TitleField="Title" PercentCompleteField="PercentComplete" OrderIdField="OrderID" />

<DependenciesDataBindings TypeField="Type" IdField="ID" PredecessorIdField="PredecessorID" SuccessorIdField="SuccessorID" />

</DataBindings>

</telerik:RadGantt>

My code behind

public XElement GetGantTasksByProjectId(int projectId)

{

using (var db = new HrNoteEntities())

{

var tasks = (from t in db.vw_sw_GanttTasks

where t.ProjectId == projectId

orderby t.ParentId, t.Start

select new

{

ID = t.ID,

ParentId = t.ParentId,

Start = t.Start,

End = t.End,

PercentComplete = t.PercentComplete == null ? 0 : t.PercentComplete,

Summary = t.Summary == 1 ? true : false,

ProjectId = t.ProjectId,

Title = t.Title

});

XElement tasksList = new XElement("Tasks");

int hasNext = 0;

foreach (var item in tasks)

{

XElement task;

if (item.ParentId > 0)

hasNext = 0;

else

hasNext = 1;

task = new XElement("Task",

new XElement("ID", item.ID),

new XElement("ParentID", item.ParentId),

new XElement("Start", item.Start.ToString()),

new XElement("End", item.End.ToString()),

new XElement("Title", item.Title),

new XElement("PercentComplete", ((decimal)item.PercentComplete).ToString("G")),

new XElement("Summary", item.Summary),

new XElement("Expanded", true),

new XElement("OrderID", item.ProjectId)

);

if (hasNext == 1 && tasksList.HasElements)

tasksList.Add(new XElement("NextID", item.ID));

tasksList.Add(task);

}

return tasksList;

}

public XDocument GetGanttByProjectId(int projectId)

{

XDocument xdoc = new XDocument();

XElement project = new XElement("Project");

xdoc.Declaration = new XDeclaration("1.0", "utf-16", "true");

project.Add(GetGantTasksByProjectId(projectId));

xdoc.Add(project);

return xdoc;

}

// Binding

GanttChart.DataSource = model.GetGanttDataSource(selectedProjectId);

GanttChart.DataBind();

Any Idea?

Thanks,

Gantt

More than one appointment with same ID

Hi

I use telerik RadScheduler for application in which i have to make reservations using the scheduler.
The problem what i have is this. Due to our database design we have reservations that use multiple resources.
For example i have reservation in which i use Resource 1 and Resource 2.
Also the application is grouped by this resources: Resource 1, Resource 2, Resource 3 ...
In our database the relation between reservation - resource is many to many so when i make select to bind it to the scheduler i have the same reservation two times, one for Resource 1 and one for Resource 2. This reservation is show twice in the Resource 1 column and in Resource 2 column.
I have allowed drag and drop functionality. Before this on the scheduler everything worked fine.
When i drag and drop the reservation from Resource 1 to another time it's OK (Resource 1 is first column, than comes Resource 2 column). But when i try to drag the reservation from Resource 2 (this is basically the same reservation as that in Resource 1) appointment update method handler doesn't get executed.
I think this is because the two reservations (in the database is one reservation) have the same ID.
In the attachment you have the image of my scenario.

Can anybody tell me how to find work around this problem.

Thanks
