RadGrid Mobile Rendering and Filterlist

I noticed that when using Mobile Rendering in RadGrid, that the Filterlist I had create does not work. Instead it does the generic filtering with the mobile view. Do I take it that Filterlist is not supported in RadGrid when using Mobile rendering?

Saving / Restoring RadGrid Layout

Using the Q3 version of the ASP.NET/AJAX RadControl Suite, is there a built-in way to save / restore the current layout (ie: filtering, sorting, column order, visible columns, etc) of the grid?

ie: Similar to what DevExpress provides: http://www.devexpress.com/Help/?document=ASPxGridView/CustomDocument4342.htm&levelup=true

I found a code sample on your help site which seems to provide a sample piece of code for this (http://www.telerik.com/help/aspnet-ajax/grdsavingsettingsonperuserbasis.html) but the code does not compile. (Haven't really dug into why...)

Thanks,

Roy

Forms authentication with Grid

Hi, I have a site which uses forms authentication and has a grid with an AJAX manager. When the session expires, I'd like the user to be bounced back to the login page. A page refresh sends me back to the login correctly. However, when interacting with the grid (sorting, filtering, etc) after the session has expired, I get the following error in a popup box:

Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 0

I searched the forum for solutions, but all the posts appear to be a few years old. What is the current solution to this problem? Thanks.

Error with AutoCompleteBox inside asp:Repeater

Hello,

I have a page that I'm building that uses a AutoCompleteBox inside of a repeater. I am trying to load the control inside of the the ItemDataBound method of the repeater, but an error gets thrown before it can even be called saying "Datasource not set" referring to the AutoCompleteBox. Is there a specific way that I should be loading the control? Here is a snippet of the control being loaded inside the ItemDataBound method of the repeater. Thanks for any help.

{

RepeaterItem item = e.item;

txtAgent = (RadAutoCompleteBox)item.FindControl("txtAgent");

txtAgent.DataSource = Agent.GetListOfAgents();

txtAgent.DataBind();

}

Include pdf/pictures attachment to final pdf

Hi,

I'm trying to generate a full report as a single pdf and I'm wondering if it's possible to add for example an existing pdf file between 2 pages of the pdf rendered ?

Should I find a way to render the pdf on a view page using third party js libraries for pdf rendering or is there a way to do this using only this component ?

Thanks,

Send other data than PDF

Would it be possible to use the ClientExportManager to send a chunk of raw data to the server.

Just send the data and skip the PDF and Image conversion part?

Thanks,

Marc

I copied the example from the autocompletedemo page, but I got this error : "The server method 'GetCompanyNames' failed."
There is a snippet of my code:

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

<div>

<fieldset style="width: 400px">

<p>

<asp:Label runat="server" ID="Label2" />

using System.Web;

using System.Web.Services;

using System.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

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

{

protected void Page_Load(object sender, EventArgs e)

{

}

[WebMethod]

public AutoCompleteBoxData GetCompanyNames(object context)

{

string searchString = ((Dictionary<string, object>)context)["Text"].ToString();

List<AutoCompleteBoxItemData> result = new List<AutoCompleteBoxItemData>();

AutoCompleteBoxItemData childNode = new AutoCompleteBoxItemData();

childNode.Text = "aaaa";

childNode.Value = "aaaa";

result.Add(childNode);

AutoCompleteBoxData res = new AutoCompleteBoxData();

res.Items = result.ToArray();

return res;

}

Thank you for your help,
Kind regards,

How to avoid IO Exception when using RadAsyncUpload

Only occasionally I am receiving the "IOException: The process cannot access the file 'file path' because it is being used by another process".

How can I handle my upload to avoid encountering this error?

Here's my code example.

On the webform page.

<telerik:RadAsyncUpload
runat="server"
ID="fileUpload"
ChunkSize="3145728"
MaxFileInputsCount="1"
AllowedFileExtensions=".htm,.html,.HTML,.doc,.DOC,.docx,.zip,.txt,.mht,.MHT,.msg,.mp4,.pdf,.PDF"
OnClientValidationFailed="uploadValidationFailed">
</telerik:RadAsyncUpload>
<telerik:RadProgressArea
runat="server"
ID="RadProgressAreaTechNotes">
</telerik:RadProgressArea>

Codebehind

foreach (UploadedFile file in fileUpload.UploadedFiles)
{
uploadedFilename = file.FileName;
asyFileExtension = file.GetExtension().Replace(".", string.Empty);
asyFileSize = file.ContentLength;
string spath = storePath + uploadedFilename;

file.SaveAs(spath);
}
