HTML encoding for RadTreeNode.Text fails

Hello

I use RadTreeView with load-on-demand feature (ServerSideCallback). When a node is expanded I create child nodes and do HtmlEncode for its' texts. I see "<input>" text as "<input>" and that's OK. But when I click any child node (I have server-side Click handler that actually do not change any nodes) all "<input>" nodes become text boxes!

I guess it's a bug. Could you give me some workaround?
Thanks.

Grid Paging doesn't work

I am currently running into a major issue where when using the paging navigation and I try to move to the next page nothing happens. I get a brief flash where the grid header row's columns adjust and then settle back to their original widths.

I might assume it's something with a Script or RadManager maybe?
Anyone have any suggestions?

"Cannot Write To Target Folder" Error

I have a File Explorer:

    
            <telerik:RadFileExplorer   
        
            ID="EquipmentFileExplorer"   
        
            runat="server"   
        
            InitialPath="~/AppData/Uploads/" 
        
            VisibleControls="TreeView, Grid, Toolbar, ContextMenus">  
        
            <Configuration   
        
            MaxUploadFileSize="2004800"   
        
            SearchPatterns="*.doc,*.pdf,*.gif,*.jpg,*.jpeg,*.tif,*.tiff"   
        
            DeletePaths="~/App_Data/Uploads/" 
        
            UploadPaths="~/App_Data/Uploads/" 
        
            ViewPaths="~/App_Data/Uploads/">  
        
            </Configuration> 
        
            </telerik:RadFileExplorer>

When I run the project, either locally or on a dev server, I receive an alert saying "Cannot Write To Target Folder". NETWORK SERVICE has modify set on the folder, so it should be ok?

I am using the latest ASP.NET release. Puzzled.

Columns don't have unique values error

Please ignore this post, I found an error in the SQL Statement

I attempting to populate a tree view via databinding and keep getting the error columns don't have unique values. The dataset results I'm binidng to is repeated below. The parent ID column has dupes because many of the parents have multiple children which I assume is fine, but the ID field is unique for all of the records. Obviously I'm missing something but I don't get it, any guidance is appreciated.

Also, here is my binding code:

Me

.RadTreeView1.DataSource = oDS.Tables(0)

Me.RadTreeView1.DataFieldID = "ID"

Me.RadTreeView1.DataFieldParentID = "ParentID"

Me.RadTreeView1.DataTextField = "Name"

Me.RadTreeView1.DataValueField = "ID"

Me.RadTreeView1.DataBind()

Cascading multi-select comboboxes

I have two comboboxes, one dependent on the other. There's a checkbox beside each item in each combobox so users can make multiple selection on each. This is how both my comboboxes are coded.

    
                        <input id="hdnProduct" runat="server" type="hidden" /> 
        
                        <telerik:RadComboBox ID="rcbProduct" runat="server" EmptyMessage="All" HighlightTemplatedItems="true" AllowCustomText="true" 
        
                            OnClientDropDownOpening="rcb_ClientDropDownOpening" OnClientDropDownClosing="rcb_ClientDropDownClosing"  
        
                            OnClientSelectedIndexChanging="rcb_ClientSelectedIndexChanging" OnClientBlur="rcb_ClientBlur"> 
        
                            <ItemTemplate> 
        
                                <asp:CheckBox ID="chk" runat="server" onclick="rcbProduct_CheckBoxClicked();" /> 
        
                            </ItemTemplate> 
        
                        </telerik:RadComboBox>

Based on every checkbox clicked, it appends the selected text in the text area on the combobox and value in the hidden input field.

After I finish making my selection here, I need to populate another combobox (which is coded in the same style) to be populated dynamically. Right now the problem I am having is how can I do it? Do I use the ClientItemRequested and ItemsRequested methods in the second combobox to populate it? Will doing so have any problem with creating the checkboxes dynamically? If so then do I need to do a full postback after the selection is complete in the first combobox (I don't want to do a full postback if possible)? Is there a better solution to this?

Thanks.

exporting with datakey problem

hi I have a radgrid with 1 detailtable. The master table is Members, the datakey is MemberId, the detailtable is Students, the datakey is StudentID. At runtime i can expand any mastertableview record to view the detailtable records. However once I click on export button i get this error: StudentID is neither a DataColumn nor a DataRelation for table Members. StudentID only exist in the StudentTable, not the Member table.... I could not understand why the Grid Exporting tries to find the StudentID in Members Table?
my export code is:

    
            RadGrid1.MasterTableView.HierarchyDefaultExpanded = true;     
        
            RadGrid1.MasterTableView.DetailTables[0].HierarchyDefaultExpanded = true;     
        
            RadGrid1.AllowPaging = false;     
        
            RadGrid1.MasterTableView.Rebind();     
        
            RadGrid1.ExportSettings.OpenInNewWindow = true;     
        
            RadGrid1.MasterTableView.ExportToCSV();

please help

Traversing all records in gird with Paging

Hello,

I have a radgrid with Paging turned on and set to display 10 items per page.

What I need to be able to do is to loop through all records in the grid, not just the 10 displayed on each page. For example, if I have 25 records, I need to loop through all 25, not just the first 10.

Is there a way to do this through Javascript?

I have tried to use the dataItems property on the grid's master table, but that only returns the items on the currently displayed page of the grid.

Thanks!
