Custom client or server events for TimeLineView Headers?

I would like to use RadScheduler in conjunction with a RadGrid. Basically, I'd like to present events in the RadScheduler's Timeline View. When a user clicks on a day in the Timeline view, I would like to load a list of all of the day's events in a RadGrid.

Is there a simple way to do this?

Load on Demand - Repeat Items

I am using Load on Demand with ShowMoreResults and I am binding to the combobox on the intitial Page_Load so the first page of results is in the combobox before a user actually requests them. I am pretty sure that this initial binding on the page_load is what is causing the problem, but it is necessary for my requirements.

When I click the more results button, the ItemsRequested event is fired off and I add more items to the combobox. When the results are finished being loaded into the combobox, I get the original first page of results with the second page after it, then the first page of results again.

Why am I getting these repeat items? How can I stop these repeat items from being added. It has something to do with the fact that I am making this initial load. I noticed when the ItemsRequested event gets called and I don't make that initial load, the combobox.items.count always starts off at 0 when the ItemsRequested event begins, but when I make that initial load, the count is always the size of my first page 100 when it begins.

Here is my aspx code for the combobox:

    
            <telerik:RadComboBox ID="testDdl" runat="server" Width="350px" Height="200px" DataTextField="DocumentId" DataValueField="MainId" Skin="Outlook" AllowCustomText="true" ShowToggleImage="true" MarkFirstMatch="true" OnItemsRequested="TestDdl_ItemsRequested" EnableLoadOnDemand="true" ShowMoreResultsBox="true" />

Here is my page load event:

    
            protected void Page_Load(object sender, EventArgs e)  
        
            {  
        
               Documents testDocuments = new Documents();  
        
               for (int i = 0; i < 100; i++)  
        
               {  
        
                  Document document = new Document();  
        
                  document.DocumentId = i.ToString();  
        
                  document.MainId = i;  
        
                  testDocuments.Add(document);  
        
               }  
        
               testDdl.DataSource = testDocuments;  
        
               testDdl.DataBind();  
        
            }

Here is my ItemsRequested event:

    
            protected void TestDdl_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)  
        
            {  
        
               int myTotalRecordCount = 1000;  
        
               const int itemsPerRequest = comparisonSetPageSize;  
        
               int itemOffset = e.NumberOfItems;  
        
               int endOffset = itemOffset + itemsPerRequest;  
        
               if (endOffset > myTotalRecordCount)  
        
               {  
        
                  endOffset = myTotalRecordCount;  
        
               }  
        
               e.EndOfItems = endOffset == myTotalRecordCount;  
        
               for (int i = itemOffset; i < endOffset; i++)  
        
               {  
        
                  RadComboBoxItem newnewItem = new RadComboBoxItem(i.ToString(), i.ToString());  
        
                  testDdl.Items.Add(newItem);  
        
               }  
        
               e.Message = "Items 1 - " + endOffset + " of " + myTotalRecordCount;  
        
            }

Sort icon click does not sort (clientside databinding)

Clicking on the sort icon does nothing. Clicking on the header text works fine.

Grid markup:

    
            <telerik:RadGrid ID="RadGrid1" runat="server" 
        
                 AllowSorting="true"

Using LINQ to search nodes?

Has anyone successfully employed LINQ to search the Nodes collection for a substring in the node's text value? I have a need to allow site visitors to search the node list without necessarily needing to know the full text of the node.

For example, if I have "Bob's Pizza" buried in the hierarchy, I'd like them to be able to search for "pizza" and select that node. My thought was to use LINQ to query the collection for matches then allow the person to go from match to match.

Has anyone done this before? Is it possible?

Rad Editor issue with alert emails

In a scenario where the rad editor is used as a replacement for the moss editor in list item editing, if you click edit on an item with two columns - title and a multiple lines of text column, make no changes to the text column thats using the rad editor control, but make a change to the title and click ok, the alert thats registered on the list will show that the text column has changed when it hasn't.

The reason seems to be that the guid in the first div element defined in the html of the control changes each time you click edit on the list item.

Using the default moss editor this is NOT the case.

If i need to clarify this problem further please let me know.

Sort GridTemplateColumn

Hi guys,

I need help with sorting a customised GridTemplateColumn. The column snippet is shown below:

    
            <telerik:GridTemplateColumn UniqueName="NameCommandColumn" AllowFiltering="False"  
        
                    ItemStyle-Width="150" HeaderStyle-Width="150" ShowSortIcon="true" > 
        
                        <HeaderTemplate>Name</HeaderTemplate> 
        
                        <ItemTemplate>               
        
                            <asp:HyperLink ID="hlnkContactName" runat="server"></asp:HyperLink>  
        
                            <asp:Label ID="lblContactName" runat="server"></asp:Label> 
        
                        </ItemTemplate>          
        
                    </telerik:GridTemplateColumn>

The column is used to display names either as a hyperlink or a simple label depending on the user's access rights. The main problem I have is that the values for these controls are generated at RadGrid's Item_Created event where it concatenates 2 strings (i.e. GivenNames & Surname) and binds the final output to the controls. See snippet below:

    
                    protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e) 
        
                    {             
        
                        if (e.Item is GridDataItem) 
        
                        { 
        
                            //Check the user's permissions. if the user has edit permissions then allow edit.                 
        
                            if (SecurityHelper.IsAllowedTo("Modify","PhoneList")) 
        
                            { 
        
                                #region Instantiate Name link 
        
                                HyperLink hlnkContactName = (HyperLink)e.Item.FindControl("hlnkContactName"); 
        
                                if (hlnkContactName != null) 
        
                                { 
        
                                    Label lblContactName = (Label)e.Item.FindControl("lblContactName"); 
        
                                    if (lblContactName != null) 
        
                                        lblContactName.Visible = false; 
        
                                    hlnkContactName.Attributes["href"] = "#"; 
        
                                    hlnkContactName.Attributes["onclick"] = string.Format("return ShowForm('{0}')", 
        
                                        Constants.URL_PHONELISTEDITOR + "?" + Constants.QUERYSTRING_PARTYID + "=" + e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["PartyId"].ToString()); 
        
                                    hlnkContactName.Text = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["GivenNames"].ToString() +" "+ 
        
                                        e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Surname"].ToString();  
        
                                } 
        
                                #endregion 
        
                            } 
        
                            else 
        
                            { 
        
                                #region Instantiate Name Label 
        
                                Label lblContactName = (Label)e.Item.FindControl("lblContactName"); 
        
                                if (lblContactName != null) 
        
                                { 
        
                                    HyperLink hlnkContactName = (HyperLink)e.Item.FindControl("hlnkContactName"); 
        
                                    if (hlnkContactName != null) 
        
                                        hlnkContactName.Visible = false; 
        
                                    lblContactName.Visible = true; 
        
                                    lblContactName.Text = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["GivenNames"].ToString() +" "+ 
        
                                        e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Surname"].ToString();  
        
                                } 
        
                                #endregion                    
        
                            } 

                      } 
        
                 }

What I would like to do, is to be able to sort the column by its final output. but I'm not sure how to go about doing it. Please help!

Image in ComboBox in Grid?

I have a ComboBox defined in a grid column as follows:

    
            <telerik:GridTemplateColumn UniqueName="den_type_id" HeaderText="Den Type">  
        
                <ItemStyle Width="175" /> 
        
                <ItemTemplate> 
        
                    <asp:Label Width="170" CssClass="gridDropDownLabel" runat="server" ID="lbl_den_type_id" Text='<%#DataBinder.Eval(Container.DataItem, "den_type_nm")%>' /> 
        
                </ItemTemplate> 
        
                <EditItemTemplate> 
        
                    <telerik:RadComboBox Width="170" MarkFirstMatch="true" Skin="scSkin" EnableEmbeddedSkins="false" DataTextField="den_type_nm" DataValueField="den_type_id" DataSourceID="DenTypeDataSource" ID="dd_den_type_id" runat="server" SelectedValue='<%#Bind("den_type_id") %>' Text="Select a Type" /> 
        
                </EditItemTemplate> 
        
            </telerik:GridTemplateColumn>

I also have a function in the code behind that adds a row

    
                Private Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGrid1.ItemDataBound  
        
                    If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then  
        
                        Dim item As GridEditableItem = e.Item  
        
                        Dim combo As RadComboBox = item.FindControl("dd_den_ldr_id")  
        
                        combo.Items.Insert(0, New RadComboBoxItem("Select a Den Leader", "0"))  
        
                    End If  
        
                End Sub

Is there a way to add an image to each item so that there's text + image? In the demos, they use ImagePath, but I can't figure out if this property is available when using the combobox in a grid column. Thanks.
