Thanks in advance,

[Solved] Preventing Transfer of Disabled Items

I have 2 ListBoxes. If an item in one ListBox is disabled I need to stop it from being transferred to the other.

I've already established that I need to limit the buttons to remove the TransferAll... options in an attempt to achieve this.

With only the TransferTo and TransferFrom buttons working it appears that you can stop the transfer of disabled items 'cos you can't select 'em, but no...

If I select an item above the disabled item and transfer it to the other ListBox, the source ListBox automatically selects the next item down in the list whether or not it is disabled". Similarly, if the disabled item is at the top of the list and I transfer all of the other items in the ListBox, the disabled item is selected when it is the remaining item and it can be transferred.

Now, I personally think that having the system select a disabled item automagically is a bug. If it's not and this functionality is by design, can I request a new property on the ListBox; AllowDisabledItemTransfer. If you set the default to true then the existing functionality will remain unchanged.

Document manager not working

Hi!
I've set the document manager to point to a virtual folder that is linked to a folder on a different site on the same server.

For some reason it's not working on the live server but the same schema does work on the test environment.

When I click on the document manager icon on the editor it opens a window where I see the manager with all controls disabled and the message "No records to display".

There is no visible error so I wonder how I can detect why it's not able to access the appropriate folder. I've played with permissions with no luck. If the folder it's a "normal" folder and not a virtual folder, works perfectly.

I just want to see a message telling me what's wrong, just that. I'm totally blind on this.

Thanks in advance!

Retain expanded hierarchy state after parent column filter

I have read and implemented the information from this post: Retain expanded/selected state in hierarchy on rebind, and it works well as long as I do not use column filtering. When I filter the parent grid columns, the incorrect data items are expanded. The index is the same, but the in data in the row is different and the child of that row should no longer be expanded.

From what I can tell, the recommended method of retaining the expanded state is based off of storing DataSetIndex of the row in a hash table. When you filter a parent column, the original parent row can change to a different index in the grid or even disappear. I would like to know the recommended practice for this scenario. Should I simply closed all expanded child grids or could I possibly use something other than an index (such as a primary key of the data row) to identify which rows should be expanded?

If I should simply kill all the child grids, what is the best way to do this?

Thanks,
Jim

Issue with RadScriptManager at page in RadWindow.

Hello, i show RadWindow from parent form:

<telerik:RadTreeView ID="tvFile" runat="server">

OnClientContextMenuItemClicking="onClientContextMenuItemClicking">

<ContextMenus>

<telerik:RadTreeViewContextMenu ID="MainContextMenu" runat="server">

<Items>

<telerik:RadMenuItem Value="Rights" Text="Rights"/>

</Items>

</telerik:RadTreeViewContextMenu>

</ContextMenus>

</telerik:RadTreeView>

<telerik:RadWindowManager ID="winManager" ShowContentDuringLoad="false" VisibleStatusbar="false"

ReloadOnShow="false" runat="server" Skin="Sunset" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="RadWindow2" Modal="true" onClientClose="OnClientClose"

NavigateUrl="UserRights.aspx" runat="server" Behaviors="Close">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

<script type="text/javascript">

function OnClientClose(oWnd, args)

{

var arg = args.get_argument();

if (arg)

{}

}

function openWin(path) {

var oWnd = radopen("UserRights.aspx?file="+path, "RadWindow2");

}

function onClientContextMenuItemClicking(sender, args)

{

var menuItem = args.get_menuItem();

var treeNode = args.get_node();

var nodeValue = treeNode.get_value();

menuItem.get_menu().hide();

switch (menuItem.get_value())

{

case "Rights":

openWin(nodeValue);

break;

}

</script>

At UserRights.aspx I need RadScriptManager for RadListBox like this:

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server"/>

<asp:Button runat="server" ID="ds" Text="fd" />

<telerik:RadListBox runat="server" ID="dcs"></telerik:RadListBox>

</form>

But when RadWindow opens at my firebug I got js error:

this._form is null

Type._registerScript("MicrosoftAjaxWeb...UI._UpdateProgress",Sys.UI.Control);

When I haven't got RadScriptManager all is OK. But I need it for RadListBox and UpdatePanel features.

Problem with reloading/refreshing treeview

Hello,

I have a problem with updating/reloading my treeview.
I have a TreeView that is popultated from a StoreProcedure. I then have some buttons that give a popup where you can enter some information that will update the DB that the StoreProcedure use to populate the TreeView.

When I call a WebService to update the DB everything works fine, it updates the database and everyone is happy, the problem is that after this I want to close my popup and reload/refhresh the TreeView, I have tried some diffrent tactics with window.close(), window.opener.location.reload() and similar and I don't get it to work. I can get the popup to close, but if I also do the reload then i just open up again and also it still doesn't refresh the treeview AND i get a question from IE about that I need to retry geting information.

I read somewhere that you could use window.open('', '_self', ''); to get rid of that message and the funny part is that I use that in another project and there it works but not here. I'll post some of my code but I don't think that helps so much I need to understand how to refresh my TreeView and if there is any smart way todo it.

function cancel_click() {
    window.open('', '_self', '');
    if (window.opener && !window.opener.closed) {
        window.opener.location.reload();
    }
    window.close();
}

That is my javascript for when someone either press the closebutton on the popup or after the WebService have succefully updated the database, it should in theory close the window and refresh the parent. I guess that there is some way to refresh the treeview also.
Please remeber that I want todo this from a popup window, and I need access to the treeview or in someway reload it.

EDIT: Forgot to mention that if I reload the page (just press F5) I still don't get the TreeView updated, but when I close the application and start it again then it refreshes as it should and I can see the post that I have added.

EDIT2: I have also tested having the window.close() before the reload, but this doesn't do any diffrence for me atm. the biggest problem I have is that when I do the reload it opens up my popup again (should only open when you press a button) and the TreeView doesn't get any new data.
