[Solved] list of complex objects as datasource

I want to try and use a list of objects as my data source where the object contains multiple fields and I am populating the listbox programmatically. If I set the Datasource of my list box to the object how can I set what fields actually show up in the listbox I tried using templates but I couldn't get that to work.

List<Keyword> resultList = keywordService.FindKeywords();

canonicalSearchResults.DataSource = resultList;

canonicalSearchResults.DataBind();

I want the Keyword's name field to appear in the textbox but be able to keep the datasource as a list of keywords so that I can later access them. Right now it calls the tostring method and displays the result but the toString method is different than what I want displayed

ListBox

The given assembly name or codebase was invalid. (Exception from HRESULT: 0x80131047)

Hello Telerik,
We are encountering an error that is very perplexing.
we found how to correct this,
if you would indicate why this fix works. This was extremely hard to
find. Is there a best practice as to how this section should be formatted in web config going forward...to avoid this.

Removing this block bypasses the error below, but it has to do with - Telerik.Web.UI.Skins.Web20.Grid.Web20.css:

<

telerik:RadStyleSheetManager ID="RadStyleSheetManagerPrePaidSettlements" runat="server">

<telerik:StyleSheetReference Name="Telerik.Web.UI.Skins.Web20.Grid.Web20.css" Assembly="Telerik.Web.UI" />

</StyleSheets>

</telerik:RadStyleSheetManager>

in the web config.....to fix
move this entry below after the 2nd verb entry and the error noted will be gone.

Delete in RadListView from ToolTip

Similar to how a RadToolTipManager is used to insert a record into a RadGrid, I have a RadListView where the user clicks a button on a record to load a tooltip to see more info about the record, including some function buttons (namely, the "Delete" button). Because other controls update both the listview and the tooltipmanager via ajax, both controls are included in RadAjaxManagerProxy ajax settings on the page. When user clicks "Delete" in the tooltip, the record should be removed from the database, tooltip hidden, and parent listview updated. Everything is working except for updating the listview.

How do you setup ajax settings so a button in the tooltip (loaded dynamically on tooltipmanager's AjaxUpdate event) can ajax update it's parent control?

French spellcheck with single quote appostrophe

Dear Telerik,

We have a problem with the French spellchecker. When spellchecking words with appostrophes, words with single quotes as appostrophe ( ' ) will be seen as error. There are no problems with real appostrophes ( ’ ). The English dictionary allows both of them while the French one doesn't.

Since a vast majority of our users will use the single quote appostrophe in their texts, having to validate and ignore manually all these false positives a gazillion times over and over makes the spellchecking a real pain in the ***. All they're left with is the impression that the spellchecker is buggy and therefore, they won't trust the result... that is, if they got the patience to go through all the spellchecking operation.

Is there a way to fix this?

Thanks in advance.

Themes

Hi,
I use themes for my controls so I set the page theme in one place and all telerik controls get that theme applied. (ie Me.Theme = "Web20")

I now have an issue where for one combo control on the page I want it to use the default skin. Setting Skin="Default" in the control doesn't override the Theme setting. How do I override it for one control?

I'm sure I've seen how to do this before but cannot find it now :(

Any pointers?

Regards,

Jon

RTF Conversion Sample

We need the RTF conversion capability for our Telerik products. However, there is definitely some problems with handilng multiple font styles within the same document. To reproduce, use the link to your demo, http://demos.telerik.com/aspnet-ajax/editor/examples/rtfexport/defaultcs.aspx

Highlight the middle paragraph, then change the font to something other than Times New Roman (like MS Sans Serif). When you select the 'Export RadEditor content to RTF' button, the resulting file still shows Times New Roman for all paragraphs. Thinking it was not using the data in the control, I even added some custom text. The new text showed in the output file, but the font still went back to Times New Roman.

Any ideas on this?

Open RW from hyperlink (inside FormView)?

Hi all,

How do I open a radWindow from a hyperlink that resides inside a formview. I need to pass some ID to the querystring, this is what my current FormView looks like:

                    <asp:FormView ID="FormViewLatestBlog" runat="server" Width="100%" OnDataBound="FormViewLatestBlog_DataBound">         
                <ItemTemplate>         
                    <div class="post">         
                        <h1 class="title">         
                            <a href="#">         
                                <asp:Label ID="LabelTitle" runat="server" Text='<%#Bind("BLOG_TITLE") %>'></asp:Label></a></h1>         
                        <div class="entry">         
                            <asp:Label ID="LabelContent" runat="server" Text='<%#Bind("BLOG_CONTENT") %>'></asp:Label>         
                        </div>         
                        <p class="meta">         
                            Posted by <a href="#">         
                                <asp:Label ID="LabelAddedBy" runat="server" Text='<%#Bind("BLOG_ADDED_USERNAME") %>'></asp:Label></a>         
                            (<asp:HyperLink ID="HyperLinkEditBlog" runat="server" CssClass="comments" NavigateUrl='<%# String.Format("~/Admin/Blogs.aspx?Edit=True&BlogID={0}", Eval("BLOG_ID")) %>'         
                                Visible="false">Edit</asp:HyperLink>) on         
                            <asp:Label ID="LabelAddedDate" runat="server" Text='<%#Bind("BLOG_ADDED_DATE") %>'></asp:Label>&nbsp;&bull;&nbsp;         
                            <asp:HyperLink ID="HyperLinkComment" runat="server" CssClass="comments" NavigateUrl='<%# String.Format("/Blog/Comment.aspx?BlogID={0}", Eval("BLOG_ID")) %>'>Leave A Comment</asp:HyperLink>         
                            (<asp:Label ID="LabelCommentCount" runat="server" Text='<%#Bind("BLOG_COMMENT_COUNT") %>'></asp:Label>)&nbsp;&bull;&nbsp;         
                            <asp:HyperLink ID="HyperLinkReadFullArticle" runat="server" CssClass="comments" NavigateUrl='<%# String.Format("~/Blog/Default.aspx?BlogID={0}", Eval("BLOG_ID")) %>'>Read full article</asp:HyperLink></p>         
                    </div>         
                </ItemTemplate>         
            </asp:FormView>         

Now I want to make the "HyperLinkComment" to open a radWindow instead of going to that page, what should I do?

Thank you very much.

Actually i have added 20 columns in child grid but i'm able to see only 14 columns (based on screen REsolution) , rest of the columns are inside that grid. If i get scrolling to that Child grid then i'm able to see those columns properly. But there are no property to enable scrolling for detailed Table view. Ultimately Horizontal scrolling is not at all working for Parent Grid also. Can you suggest me how to Enable Horizontal Scrolling
