Questions on UI for ASP.NET AJAX Forum

I have a Modal ToolTip with ShowEven and HideEvent both set to FromCode. The ToolTip displays a panel that contains a RadGrid and two buttons. The Grid is set to allow column filtering.

When I run the page and display the ToolTip it works fine. However, if I apply a filter, that causes a PostBack which "closes" the ToolTip. I think from other posts I have read that I need to either reshow the ToolTip or "ajaxify" the grid so that the postback is only a partial.

What's the best approach? If I decide to reshow the ToolTip, how do I determine that it was supposed to be open? If I decide to ajaxify the interaction, what settings? I tried setting the Grid as the Target and the ToolTip as the Updated control but that didn't help.

Detect if ToolTip is Open

I have a ToolTip that is set to Modal with the ShowEvent and HideEvent both set to FromCode. Is there a way to determine if the ToolTip is showing in the CodeBehind?

RadWindow close error on second display

Hello,

I have a project that basically looks like this:

Default.aspx - the page from which all activity begins
Vendors.aspx - a page displayed in a RadWindow opened from Default.aspx
VendorDetails.aspx - a page displayed in a RadWindow opened from Vendors.aspx which is used to add/edit a vendor.

When I open for the first time the Vendors window from Default.aspx and do some add/edit operation using the VendorDetails window (close/open several times), there is no problem. After I close the Vendors window, then open it again from Default.aspx, then open the VendorDetails, the first time I close the VendorDetails window, I get an error: Microsoft JScript runtime error: Can't execute code from a freed script.

I'm displaying the VendorDetails using Javascript:

var parentRadWindowManager = GetRadWindow().BrowserWindow.GetRadWindowManager();

var oWnd2 = parentRadWindowManager.open("VendorDetails.aspx?VendorID=0", "rwAddNewVendor");

window.setTimeout(function () {

oWnd2.set_title("Add new vendor");

oWnd2.setActive(true);

oWnd2.set_modal(true);

oWnd2.setSize(800, 420);

oWnd2.set_behaviors(Telerik.Web.UI.WindowBehaviors.Move + Telerik.Web.UI.WindowBehaviors.Close);

oWnd2.set_visibleStatusbar(false);

oWnd2.set_showContentDuringLoad(false);

oWnd2.center();

oWnd2.add_close(RefreshGrids);

}, 0);

return false;

I suspect the problem is in the VendorDetails.aspx RadWindow. This window contains the following Javascript:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function GetRadWindow() {

var oWindow = null; if (window.radWindow)

oWindow = window.radWindow; else if (window.frameElement.radWindow)

oWindow = window.frameElement.radWindow; return oWindow;

}

function windowClose() {

var oWindow = GetRadWindow();

oWindow.showConfirm = false;

oWindow.argument = null;

oWindow.close();

return false;

}

</script>

</telerik:RadCodeBlock>

http://www.toplinestrategies.com/dotneters/random-error-message/random-error-message-sys-webforms-pagerequestmanager-getinstance-_destroytreeb/?lang=en
http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-vs2010-bug.aspx

I do not have RadAjaxManager either on the page or master page which it's use ( But it's there in other pages of application), but I do have the RadComboBox on the same page.
Can you please tell me is there any workaround available for the version of telerik we are using??

GetRadWindowManager and $find()

Hi,

I have been unsuccessful in obtaining a reference to the RadWindowManager via the GetRadWindowManager or the $find() calls.

$find returns null and GetRadWindowManager returns undefined.

Any help would be greatly appreciated.

Thanks in advance,

SortAscImageUrl or SortDescImgUrl in GridTemplateColumn?

Hi, I can't seem to get my sort arrow icons to appear for a GridTemplateColumn. There isn't even an "X" appearing as if it didn't find the file. Is there something special I need to do?

<telerik:RadGrid ID="grdSearchResult" EnableEmbeddedSkins="false" ImagesPath="~/Images" runat="server" AllowSorting="true" AutoGenerateColumns="false" OnSortCommand="grdSearchResult_SortCommand" OnItemDataBound="grdSearchResult_OnItemDataBound">

<telerik:GridTemplateColumn ShowSortIcon="true" SortAscImageUrl="~/Images/down.png" SortDescImageUrl="~/Images/up.png">

....

Is there another setting or something I need to do in the OnSortCommand event? Thanks, Dave

Page Layout+RadTabStrip

I have this error

The Visible property cannot be set on Web Part 'g_XXX'. It can only be set on a standalone Web Part.

It gives error when add document to list webpart which is in radtabstrip's tab. Or when i want to edit page.
Everybody says not use "webpart.visible", use "webpart.hidden" but i did not do anything on code. Maybe radtabstrip doing this?
What is the problem and how can i fix this?
I have a pagelayout like this,

Weird problem with upload sometimes not working

I have a strange problem!
When I upload via the windows explorer upload facility on 4 out 60 directories it does not upload the files.

The directories are all created via Directory.Create();
The 4 directories that are in question are not the longest file names, but all have similar names, they are:
Safari Bella Leopard
Safari Bella Zebra
Safari Tall Leopard
Safari Tall Zebra

yet the file names:
Safari Short Zebra Collection
Safari Short Leopard Collection
work fine and more interestingly I can create the dummy file "blah.txt" (as you can see in the code below) in the directories that are having the issues.

Below is the code I use

<telerik:RadFileExplorer ID="RadFileExplorer1" Runat="server"

Width="600px" EnableAsyncUpload="True"

EnableCreateNewFolder="False" ExplorerMode="Thumbnails"

VisibleControls="Toolbar, ContextMenus, FileList"

AvailableFileListControls="Thumbnails" Skin="Office2010Blue">

<Configuration EnableAsyncUpload="True" SearchPatterns="*.*" />

</telerik:RadFileExplorer>

string physicalPath = Directory.GetParent(Server.MapPath("").ToString()).ToString() + "\\Product Images\\" + Request.QueryString["id"].ToString();

if (!Directory.Exists(physicalPath))

{

try

{

Directory.CreateDirectory(physicalPath);

}

catch (Exception ex) { RadAjaxManager1.Alert(Misc.CleanForDatabase(ex.Message)); }

}

try

{

File.CreateText(physicalPath + "/blah.txt");

}

catch (Exception ex1) { RadAjaxManager1.Alert(ex1.Message); }

string[] relativePath = new string[] { "~/Product Images/" + Request.QueryString["id"].ToString() + "/" };

RadFileExplorer1.Configuration.UploadPaths = relativePath;

RadFileExplorer1.Configuration.DeletePaths = relativePath;

RadFileExplorer1.Configuration.ViewPaths = relativePath;

RadFileExplorer1.Configuration.MaxUploadFileSize = 10485760;

I hope someone has some ideas on this... I have exhausted all of mine ((

Thanks in advance :)
