Hi
I have a radsplitter and I am trying to collapse it on a button click. OnClientClick of the button, I have this method called.
function OnCollapse()
{var splitter = "<%= RadSplitter1.ClientID %>";
var pane = "<%= radPaneAdminLeftMenu.ClientID %>"
pane.Collapse();
return false;
}
It says pane.Collapse() is not supported.

Microsoft JScript runtime error: Object doesn't support this property or method

Please advice.
Thanks.

 

Hello,

I'm new to Telerik and we are evaluating the tool sets, and so far I like what I see, but I am currently stuck on a problem with the treeview.

The goal, is to have a tree view that is comprised of folders and of reports, and when the user drags the report into the viewer, it loads (right now it's off a button click).

I have the hierarchy working, but I don't think I'm currently doing this correctly. Namely, I haven't figured out how to identify if a RadTreeNode is a Folder, or a Report, which is causing some issues. Secondly, I'm trying to set it where the folders, use the image Icons we have in the project (which I've been able to do) but because I can't 100% tell if it's a report or a folder, the only way I can set it is via if the node has no children, which won't always be the case.

I've got a lot of work to do in cleaning this up, so I figured I'd post this question and hopefully get some direction. I've been reading the documentation and it has helped me get this far, so I'll go ahead and post my code:

Thanks,

Here is my TreeView

<telerik:RadTreeView ID="reportsTree" Runat="server" EnableDragAndDrop="True" EnableDragAndDropBetweenNodes="True" Height="100%" RenderMode="Auto" Skin="Outlook" BorderStyle="Solid" BorderWidth="2px" OnNodeDrop="reportsTree_NodeDrop">
                    </telerik:RadTreeView>
                    <telerik:RadContextMenu ID="treeMenu" Runat="server" Skin="Office2010Blue" OnItemClick="treeMenu_ItemClick">
                        <Targets>
                            <telerik:ContextMenuControlTarget ControlID="reportsTree" />
                        </Targets>
                        <Items>
                            <telerik:RadMenuItem runat="server" Text="Create Folder">
                            </telerik:RadMenuItem>
                            <telerik:RadMenuItem runat="server" Text="Delete Folder">
                            </telerik:RadMenuItem>
                        </Items>
                    </telerik:RadContextMenu>

I have a context menu, that I need to hook up to some events, and will do that later.

Here is the code behind that populates the TreeView

private void CreateTreeView()
        {
            // Get the list of folders
            List<Report_Folders> _folders = new List<Report_Folders>();
            _folders = rm.Report_Folders.Where(x => x.isUserFolder == false && x.isPublished == true).ToList();

            List<Report_Folders> _myFolders = new List<Report_Folders>();
            _myFolders = rm.Report_Folders.Where(x => x.isUserFolder == true && x.isPublished == true && x.UserID == myProfile.Id).ToList();

            // Get the list of reports
            List<Report> _reports = new List<Report>();
            _reports = rm.Reports.Where(x => x.OwnerID == 0 && x.isPublished == true).ToList();

            List<Report> _myReports = new List<Report>();
            _myReports = rm.Reports.Where(x => x.OwnerID == myProfile.Id && x.isPublished == true).ToList();

            List<TreeViewItem> treeNotes = new List<TreeViewItem>();

            //foreach (Report_Folders item in _folders.Where(x => x.ParentID == null && x.isPublished == true))
            //{
            //    treeNotes.Add(new TreeViewItem(item.FolderName, item.FolderID, item.ParentID, _folders, _reports));
            //}

            foreach (Report_Folders item in _folders)
            {
                treeNotes.Add(new TreeViewItem(item.FolderName, item.FolderID, item.ParentID, true, null));
            }

            foreach (Report_Folders item in _myFolders)
            {
                treeNotes.Add(new TreeViewItem(item.FolderName, item.FolderID, item.ParentID, true, null));
            }

            foreach (Report item in _reports)
            {
                treeNotes.Add(new TreeViewItem(item.ReportName, item.ReportID, item.FolderID, false, item));
            }

            foreach (Report item in _myReports)
            {
                treeNotes.Add(new TreeViewItem(item.ReportName, item.ReportID, item.FolderID, false, item));
            }

            reportsTree.DataFieldID = "ValueID";
            reportsTree.DataValueField = "ValueID";
            reportsTree.DataTextField = "ValueName";
            reportsTree.DataFieldParentID = "ParentID";
            //reportsTree.data
            reportsTree.DataMember = "TreeViewItem";
            reportsTree.DataSource = treeNotes;

            ddlFolders.DataSource = treeNotes.Where(x => x.isFolder == true);
            ddlFolders.DataTextField = "ValueName";
            ddlFolders.DataValueField = "ValueID";
            ddlFolders.DataBind();

            reportsTree.DataBind();

            foreach (RadTreeNode item in reportsTree.Nodes)
            {
                foreach (RadTreeNode sub in item.Nodes)
                {
                    sub.ImageUrl = "~/Content/Images/SmallImages/folder.png";
                    sub.ExpandedImageUrl = "~/Content/Images/SmallImages/open.png";
                }

                item.ImageUrl = "~/Content/Images/SmallImages/folder.png";
                item.ExpandedImageUrl = "~/Content/Images/SmallImages/open.png";
            }

            reportsTree.ExpandAllNodes();
        }

As you can see, I have a collection of TreeViewItem which I populate from the Reports_Folders table, and the Reports table. It has properties like this:

public TreeViewItem(string Name, int ID, int? _pID, bool _isThisfolder, Report _reportValue)
        {
            this.ValueId = ID;
            this.ValueName = Name;
            this.ParentID = _pID;
            this.isFolder = _isThisfolder;
            this.SelectedReport = _reportValue;
        }

I would like to set it's image properties, but for the time being, I don't know if I'm doing this correctly, or if there is a better way to go about setting up this tree view the way that I want it to be handled. 

The main issue right now, is that I can't seem to get TreeViewItem from the selected node in the treeview, so I'm a bit confused. 

If you can help point me in the right direction that would be fantastic. I've been reading the documentation over on http://www.telerik.com/help/aspnet-ajax/treeview-data-binding-hierarchical.html but am still not 100% there.

Contrary to what I mentioned in this thread...

http://www.telerik.com/forums/missing-dropdown-scrollbar#VJvAA0Py9kitURlSmCO7iw

It would appear that the Dropdownlist control suffers from the same issue of not displaying scrollbars and calculating its height from available screen space (a la radcomobox) without explicitly setting a DropDownHeight property. Why is this so? It doesn't make any sense.

I have Telerik Assemblies (old and new) registered in GAC.
i want that my RadImageEditorControll run with new assemby. How can i do it?

i want all my application and controlls to run with old assembly only radimageeditor to run with new assembly?
is there any way to do it in web.config?

How can I check or uncheck the button from server side?  I'm using the following code to set the checked state of the Radbutton control from the server side to no avail.

When i click on insert image tool on RadImageEditor it asks for a url and when i give an image url in it and SET, image is placed on the RadImageEditor Canvas but i am unable to save that from RadImageEditor after insertion of image from url.
Even i have tried it from your demo but i am unable to save after insert image. is it a BUG?
http://demos.telerik.com/aspnet-ajax/imageeditor/examples/toolbarmodes/defaultcs.aspx  and   http://demos.telerik.com/aspnet-ajax/imageeditor/examples/canvassupport/defaultcs.aspx are the demos i have used and https://yt3.ggpht.com/--5R1fXG2ZC0/AAAAAAAAAAI/AAAAAAAAAAA/dxGi8Yriddc/s100-c-k-no/photo.jpg   is the image i have used.

Hi,

are you publishing somewhere the RadScheduler database schemas used in your sample applications?

Thanks,

Hello,

I am working on a project with a RadWindow.
Controls are added dynamically to the RadWindow. (TextBox, radioButton CheckBox etc.)
The user can enter data into the dynamic controls. 

My ASPX code::

VB.NET:


How can I access the controls and the data which the user entered?
I want to retrieve this information when the user clicks a button.

Thanks,

Daniel.

Hi am able to select value on server side but I am not able to add the same selected node text on client are. My code is mention below.
RadTreeNode node = rdTreeView.FindNodeByValue(nodeValue);
if (node != null)
{
    node.Checked = true;
}

Means When we select node using "OnClientEntryAdded" then node is checked and text belong to node will available to client area. But the same is not working when we do it programmatically

Hi,

Can you help me with the following.

I'am using the RadGrid inside the RadComboBox itemtemplate and I have problems with setting the combobox selected text/value on grid's OnRowSelected client side event. When I select a row from grid after the page has been loaded then the combobox selected text will be every grid row's values concatenated but when I select a new row after that then the selected text will be displayed correctly. Can you tell me why this happens?

I also want to access the combobox selected text/value on server side after postback. I added trackChanges() and commitChanges() methods like below but still the combo.ClientChanges count property is 0 e.g. after asp:button click.

Grid is grouped by two columns, so is it possible to configure combobox so that if user clicks the category row then combobox should not be closed?



Thanks,
Pete
