Hi,

I am getting this error randomly on a page which has a lot of Telerik Controls, RadGrid, RadDock, RadToolTip and other.

Error : Sys.ScriptLoadFailedException : The script /Test/Telerik.Web.UI.WebResource.axd?_TSM_HiddenField......... could not be loaded.

The error is not coming all the time and sometime only it comes.

Any suggestion for solving this?

Thanks.
Jimmy.

Export row to csv using ItemCommand

I have a grid with at most 10 rows. Each has a button (buttoncolumn) that will export that row's fields to CSV. I'm unable to export only the row when I click the button. It exports all the rows. I tried hiding the other rows but it didn't work.

protected void rgridAdp_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "Export")

{

GridDataItem dataItem = e.Item as GridDataItem;

int batchId = StringHandlers.GetSafeInteger(dataItem["BatchNumber"].Text);

foreach (GridDataItem item in rgridAdp.MasterTableView.Items)

{

if (StringHandlers.GetSafeInteger(item["BatchNumber"].Text) == batchId)

{

item.Visible = true;

item.Display = true;

}

else

{

item.Display = false;

item.Visible = false;

}

rgridAdp.ExportSettings.FileName = "ADPExport-" + batchId;

rgridAdp.ExportSettings.ExportOnlyData = true;

rgridAdp.ExportSettings.OpenInNewWindow = true;

rgridAdp.MasterTableView.GetColumn("Export").Visible = false; // don't export button

rgridAdp.MasterTableView.ExportToCSV();

[Solved] Scheduler inside a scrolling div

Hello, I have a page that has scrolling disabled on the page so that the header stays in place. Instead there is a div on the page below the header that has scrolling enabled. When I put a scheduler in the div, it does not stay within the div. This simple bit of code is enough to demonstrate the issue:

<div style="height:300px;width:300px;overflow:scroll;">

<Telerik:RadScheduler runat="server" OverflowBehavior="Expand"

DataKeyField="none" DataSubjectField="none" DataStartField="none" DataEndField="none" />

</div>

Another option that I have tried is to use the built-in scrolling of the scheduler:

<Telerik:RadScheduler runat="server" OverflowBehavior="Scroll"

DataKeyField="none" DataSubjectField="none" DataStartField="none" DataEndField="none" />

But in this case a height for the scheduler needs to be decided ahead of time. The scheduler will either not fill the available space or it would expand outside of the div. As far as I can tell, the height can't be adjusted to take up all the available space using the client-side API when the window is resized. (I had success doing this with the RadSplitter on other pages.)

Is there a solution that would allow all the available space to be taken up without the scheduler expanding outside of the div, even when the window is resized?

Please let me know if there are other options.

File corrupted using multiple upload

I got this problem when I tried to upload 2 or more file at 1 time. The uploaded files are corrupted. But if upload just 1 file, the uploaded file will be ok. The files were saved in the session so that can be validate at the next page and then save to a document library. I'm using 2009.3.1314.20 version

Here some of the code:
1st Page
aspx:

<telerik:RadUpload ID="Upload1" runat="server" MaxFileInputsCount="5" Width="600px" InitialFileInputsCount="1" ControlObjectsVisibility="RemoveButtons, AddButton" />

<asp:Button ID="Button1" runat="server" Text="OK" OnClick="Button1_Click" />

Codebehind:

private void SaveFilesToSession()

{

IList list = new List<UploadedFileInfo>();

foreach (UploadedFile uploadedFile in UploadDocument.UploadedFiles)

{

int fileLength = uploadedFile.ContentLength;

byte[] buffer = new byte[fileLength];

uploadedFile.InputStream.Read(buffer, 0, fileLength);

UploadedFileInfo info = new UploadedFileInfo();

info.Name = uploadedFile.GetName().Trim();

info.FileInByte = buffer;

info.ContentLength = uploadedFile.ContentLength;

list.Add(info);

}

Session["UploadedFiles"] = list;

}

protected void ButtonSubmit_Click(object sender, EventArgs e)

{

SaveFilesToSession();

Response.Redirect("Upload2.aspx");

}

Thanks in advanced.

RadScheduler and RadXmlHttpPanel?

Is it possible to have the ServiceRequest of a RadXmlHttpPanel to load/refresh the data of a RadScheduler?

Or, can the RadScheduler only work via a DataSource and postbacks when using navigation?

What I'm trying to do is eliminate the postbacks when navigating to the previous/next month.

Thanks.

[Solved] persist states

There is a radgrid on my aspx page. I did some sorting and filtering, and selected a different gridpage.
After a while I return to this aspx page, then all the sorting and filtering and current selected gridpage are lost.
Is there a setting or something in the radgrid which can automatically persist all these states without me having to hardcode the logic?

Two Dependent RadMenus

Hi,

Is there a working example of how to get the RadMenu to cause an ajax request that occurs when a user mouses over a menu item, pass that item text to the server, then use that name as a key to look up other items to populate another dependent RadMenu? I have tried this using the following code but was unsuccesful.

UserControl.ascx

<div id="CloudDropDown" class="clearfix">

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

<script type="text/javascript">

function ChangeSubMenu(s, e) {

$find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequestWithTarget("<%= mainMenu.UniqueID %>", e.get_selectedItem().get_text());

}

</script>

</telerik:RadCodeBlock>

<telerik:RadAjaxManagerProxy ID="ajaxManagerProxy" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="mainMenu">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="subMenu" LoadingPanelID="radAjaxLoadingPanel" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManagerProxy>

<telerik:RadMenu ID="mainMenu" runat="server" DataSourceID="SitemapDataSource1" Flow="Horizontal" OnClientMouseOver="ChangeSubMenu" MaxDataBindDepth="1" EnableEmbeddedSkins="false" Skin="MedpacRed">

</telerik:RadMenu>

<telerik:RadMenu ID="subMenu" runat="server" EnableEmbeddedSkins="false" Skin="MedpacRed" Visible="false">

</telerik:RadMenu>

<asp:SiteMapDataSource ID="SiteMapDataSource1" runat="server" ShowStartingNode="false" />

</div>

UserControl.ascx.cs

protected void Page_Load(object sender, EventArgs e)

{

RadAjaxManager manager = RadAjaxManager.GetCurrent(Page);

manager.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(manager_AjaxRequest);

}

protected void manager_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

Guid rootGui = Utility.FindPageGuid(e.Argument);

List<SiteNavigationItem> items = Utility.ConvertCmsPages(Utility.FindChildren(e.Argument), rootGui);

subMenu.DataSource = items;

subMenu.DataTextField = "Text";

subMenu.DataNavigateUrlField = "Url";

subMenu.DataFieldID = "ID";

subMenu.DataFieldParentID = "ParentID";

subMenu.EnableEmbeddedSkins = false;

subMenu.DataBind();

subMenu.Visible = true;

}

Here is my master page that houses my user control.

<%@ Master Language="C#" AutoEventWireup="true" CodeFile="Base.master.cs" Inherits="App_Master_Base" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<body class="outthere">

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

<telerik:RadAjaxManager ID="ajaxManager" runat="server" />

<telerik:RadAjaxLoadingPanel ID="radAjaxLoadingPanel" runat="server" BackgroundPosition="Center" Skin="Default" />

<div id="pageWrapper">

<div id="page">

<div id="header" class="clearfix">

<div id="medpacBanner" class="clearfix">

<div id="logo">

<img id="medpaclog" runat="server" src="~/App_Themes/MedpacRed/images/medpacLogo.gif" />

</div>

<div id="menu" class="clearfix">

<asp:ContentPlaceHolder ID="contentMenu" runat="server"/>

</div>

<div id="genericBanner">

<img id="Img1" runat="server" src="~/App_Themes/MedpacRed/images/PinTek_MedPak_WebsiteBanner.png" alt="banner" width="1000" />

</div>

<div id="contentWrapper" class="clearfix">

<div id="content" class="clearfix">

<div id="baseMainContentWrapper">

<asp:ContentPlaceHolder ID="baseContent" runat="server"/>

</div>

<div id="footer">

<asp:ContentPlaceHolder ID="contentFooter" runat="server"/>

</div>

</div>

</div>

</div>

</form>

</body>

</html>

Can this be accomplished or am I doing something wrong?

Thanks for you help,
Bobby

Completely hide the input textbox field

I have a requirement to have the upload control completely hide the textbox. Essentially I only want to show the "browse" button to the user.

Previously I was able to achieve this by setting: ControlObjectsVisibility="None"
and then using the CSS:
            .ruFakeInput
            {
                display: none;
            }

After upgrading the Telerik controls (Q2 2010) I have noticed that in IE8/7 that the textbox now displays.
I found this: http://www.telerik.com/help/aspnet-ajax/upload-how-to-hide-input-textbox.html

Which uses slightly different CSS but this does not help either.

Any ideas?

Cheers
Aaron
