The data area passed to a system call is too small.

I am using Telerik.Web.Design version 2010.1.630.20, and get the following error when opening the document manager of the telerik editor:

The data area passed to a system call is too small.

I have been in touch with my hosting provider, and they believe this is because the code needs 'full trust level' whereas the host only provides 'medium trust level'.

How can I fix this?

Thanks

RadDock Custom Attributes Undefined in FireFox

I have a simple program where I assign attributes to a raddock in Page_Load and then pull these attributes using Javascript when the dock is moved (dock.get_element().MyAttribute). In IE, this works great, but in FireFox and Safari the "get_element().MyAttribute" always returns "undefined". I'm assuming it is simple syntax, but need some guidance.

ASPX:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

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

<script type="text/javascript">

var zones;

function OnClientInitialize(dock, args) {

zones = Telerik.Web.UI.RadDockZonesGlobalArray;

}

function OnDockChangedPosition(dock, args) {

var zone;

zone = dock.get_dockZone();

var sDockJustMoved;

sDockJustMoved = "";

sDockJustMoved = dock.get_element().TestDock + "~" + zone.get_element().TestZone;

alert(sDockJustMoved);

}

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title>Untitled Page</title>

RadGrid Paging after bending from search

Hi,
In this case I am binding the grid programmatically in the page load, then when a user does a search, I am binding the grid with a different dataset, when I enable paging after the search it binds back the original dataset; here is the code:

public partial class PageSearch : System.Web.UI.Page

{

public ACHPagingDLL.dl dl = new ACHPagingDLL.dl();

protected void Page_Load(object sender, EventArgs e)

{

LoadGrid();

}

public void LoadGrid()

{

DataSet dsPatients = dl.c_FN_Paging_getAllEmployees();

rgEmployees.DataSource = dsPatients;

rgEmployees.DataBind();

}

protected void btnSearch_Click(object sender, EventArgs e)

{

if (txtSearch.Text.Length < 2)

{

litResult.Visible = true;

litResult.Text = "<FONT color=#cc0000 size=3>Search for 2 or more characters!</FONT>";

LoadGrid();

return;

}

else

{

DataSet dsSearch = dl.c_FN_seachEmployees(txtSearch.Text);

rgEmployees.DataSource = dsSearch;

rgEmployees.DataBind();

}

And here is the HTML:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

<table class="style4">

<tr>

<td class="style5">

Search for employee by name:</td>

<td class="style6">

<telerik:RadTextBox ID="txtSearch" Runat="server" Width="160px">

</telerik:RadTextBox>

<telerik:RadButton ID="btnSearch" runat="server" onclick="btnSearch_Click"

Text="Search">

</telerik:RadButton>

</td>

<td>

<asp:Literal ID="litResult" runat="server"></asp:Literal>

</td>

</tr>

<tr>

<td colspan="3">

<telerik:RadGrid ID="rgEmployees" runat="server" AllowPaging="True"

AutoGenerateColumns="False" GridLines="None" Skin="WebBlue">

<MasterTableView pagesize="20">

<CommandItemSettings ExportToPdfText="Export to Pdf">

</CommandItemSettings>

<Columns>

<telerik:GridBoundColumn DataField="EmployeeNo" UniqueName="EmployeeNo"

Visible="False">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="EmployeeName" HeaderText="Employee"

UniqueName="EmployeeName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Pager" HeaderText="Pager"

UniqueName="Pager">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Office" HeaderText="Office#"

UniqueName="Office">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Cell" HeaderText="Cell Phone"

UniqueName="Cell">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Email" HeaderText="Email"

UniqueName="Email">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<HeaderContextMenu EnableImageSprites="True"

CssClass="GridContextMenu GridContextMenu_Default">

</HeaderContextMenu>

</telerik:RadGrid>

</td>

</tr>

<tr>

<td colspan="3">

</td>

</tr>

</table>

</telerik:RadAjaxPanel>

I am not sure if there should be a code to be inserted in the index paging?
Please let me know.

Thank you in advance,
Shehab

Mega Drop-Down with XML file?

Hello,

I am currently using the regular menu control and loading an XML file for the content of the menu. Can this still be down when using a mega drop-down? How would the XML file be structured? I haven't found any information on this and I am guessing that the mega drop-down doesn't support this...

thanks,

Steve
