Im using radgrid in a custom module in DNN Community Edition 06.01.04 which uses Teletik.Web.UI 2011.3.1115.35.
However I cant get radgrid's deletes, change page... commands to work.
Im using LinqDataSource
I get this error:

Refreshing RadGrid after downloading file via ashx

I have a grid with a column that shows whether a file has been downloaded or not (via an image in a grid column)

When the user clicks the Checkout toolbar button, I call an .ashx file, which downloads the file to the user's desktop and updates the the database that the file's been checked out. The issue I'm having is that when I try and refresh the grid by calling the grid.rebind method (on either the client or server side), not all the logic in the .ashx file gets executed (well, the database is updated, but the file isn't downloaded).

How can I refresh the grid on the client side after *successfully* calling the ashx method (where successfully means the file is downloaded *and* the database is updated)?

Here's the relevant code:

function CheckOut(){

var isExternal = false;

var rgGrid = $find("<%= rgAttachmentVersion.ClientID %>");

if ( rgGrid._selectedIndexes[0] == null ) {

rgGrid = $find("<%= rgExternalAttachment.ClientID %>");

isExternal = true;

}

var selectedVersionId;

if ( isExternal ) {

selectedVersionId = rgGrid._clientKeyValues[rgGrid._selectedIndexes[0]].ID + "&isExternal=true";

} else if ( rgGrid._selectedIndexes[0].indexOf(":") > 0 ) {

selectedVersionId = rgGrid._clientKeyValues[rgGrid._selectedIndexes[0]].ID;

} else {

selectedVersionId = rgGrid.MasterTableView.getCellByColumnUniqueName(rgGrid.MasterTableView.get_dataItems()[rgGrid._selectedIndexes[0]],

"OpenVersion").innerHTML;

}

var finalUrl = "~/VersionCheckoutHandler.ashx?id=" + selectedVersionId + "&callback=false" + "&rand=" + Math.random(); // add random number to make sure the browser does nto cache it

var xhReq = new XMLHttpRequest();

xhReq.open("GET",$Url.resolve(finalUrl),false);

xhReq.send(null);

if ( xhReq.responseText == "FILEDOWNLOADERROR" )

{

alert("An error has occurred. Please contact your system administrator.");

}

else if ( xhReq.responseText == "VERSIONALREADYCHECKEDOUT")

{

alert("This version is currently checked out.");

refreshAttachmentList();

}

else if ( xhReq.responseText == "UNABLETOCHECKOUTREMOTEREPOSITORY")

{

alert("This version is unable to be checked out from the remote repository.");

}

else

{

triggerIsPostBack = true;

window.location = $Url.resolve("~/VersionCheckoutHandler.ashx?id=" + selectedVersionId + "&callback=true");

triggerIsPostBack = false;

}

I have a client-side call that rebinds the grid (below) successfully from other methods, but when I call that after calling the CheckOut function, the file isn't saved locally (even though the grid rebinds).

function refreshAttachmentList() {

try{displayLogoffWarning = false;} catch(ex) {}

try {

$find("<%= rgAttachmentVersion.MasterTableView.ClientID %>").fireCommand('<%=RadGrid.RebindGridCommandName %>');

} catch (ex) { }

try {

$find("<%= rgExternalAttachment.MasterTableView.ClientID %>").fireCommand('<%=RadGrid.RebindGridCommandName %>');

} catch (ex) { }

}

Customize Floating Toolbar

Hello,

I would like to assign the Floating Toolbar with a behavior similar to the PageTop mode: will open on the top of the page, floating (pinned) by default, but will allow unpin and user reposition as option.
I set the Toolbar Mode to "Floating" and added the following code in OnClientLoad:

function OnClientLoad(editor, args) {

// Pin the Floating Toolbar

var wnd = editor.get_toolAdapter().get_window();

wnd.add_show(function () {wnd.togglePin();});

// Activate The Toolbar

editor.get_toolAdapter()._showToolbarHolder(true);

// Set Focus to the Editor

editor.setFocus()

// Move the Floating Toolbar to the Top

editor.get_toolAdapter().get_window().moveTo(0, 0);

}

However, it seems togglePin() function prevents the reposition of the Toolbar (Toolbar reposition works fine when togglePin() is commented out), can I integrate both functionalities?

Also (very different issue), is there a way to make the editor inherit all styles from the location it is opened (assuming div content area is used)? I know I can assign a class that includes all required styles but I would like the styles to be automatically inherited in the editor content area.

Thanks in advance!

How to disable the timeslot focus

How can I disable the focus being set in a timeslot when clicked? It is mighty slow even on IE9, and I don't need it.
When having a few dozens appointment in the control, it could take several seconds for the control to set the focus with the style, then raise the OnClientTImeSlotClick event.

I just need the event OnClientTimeSlotClick to be raised, but with no change in the style of the time slot.
Changing the style itself, will not help, because still will be applied by the browser, I will like to remove the application of the style all together while leaving the raising of the event OnClientTimeSlotClick intact.
