How do I get search engine results programatically?

How do I get search engine results programatically? Some search engines use AJAX to display content and so the URL does not change. This makes it difficult to get result content from a search engine programatically.

Most search engines do not use AJAX. But two popular ones that I am interested in is YANDEX and DUCKDUCKGO. Both of these search engines use AJAX to advance beyond the first page of results. How do I find a way to programatically access these pages?

Management of many records

Hi,
since the sql select using the radcombox charged over 1000 records, you can upload a video, when I open the radcombobox, only 10 records at a time? And then you decide to continue to view other records.
Maybe I need to use the property ShowMoreresultsBox = True?
My side code vb net is:

Protected Sub RadComboBox1_ItemsRequested(sender As Object, e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs) Handles RadComboBox1.ItemsRequested

Dim sqlSelectCommand As String = "SELECT [id], [descrizione] from [tab_categorie] WHERE [descrizione] LIKE @desc + '%' Order By [descrizione]"

Dim adapter As New SqlDataAdapter(sqlSelectCommand, ConfigurationManager.ConnectionStrings("TrycontactString").ConnectionString)

adapter.SelectCommand.Parameters.AddWithValue("@desc", e.Text)

Dim dataTable As New DataTable()

adapter.Fill(dataTable)

For Each dataRow As DataRow In dataTable.Rows

Dim item As New RadComboBoxItem()

item.Text = DirectCast(dataRow("descrizione"), String)

item.Value=dataRow("id").ToString()radComboBox1.Items.Add(item)

item.DataBind()

Next

End Sub

While the ASP side code is:

<telerik:RadComboBox ID="RadComboBox1" Runat="server" DropDownWidth="325px"

EmptyMessage="Choose a Catogory" EnableLoadOnDemand="true" Filter="Contains"

Height="150" HighlightTemplatedItems="true"

OnItemsRequested="RadComboBox1_ItemsRequested"

Width="325px" ErrorMessage="Dato errato" IsCaseSensitive="True">

</telerik:RadComboBox>

RadFileExplorer with EnableAsyncUpload

I have a page with RadFileExplorer and EnableAsyncUpload="true" option. We are using selenium tool for automation testing. But we are not able to perform "click" option with EnableAsyncUpload option.

If i remove EnableAsyncUpload option then i am able to do it.

Our findings are as below
---------------------------------------------------------------------------------------------

1) There are 2 separate objects, a "text" and a "button" manually clicking on which the Select File window opens. However, through Select IDE and Selenium RC, on performing click on these objects, the Select File window does not open, due to which AutoIT is unable to select the file to upload. This looks to be more of a selenium issue that though the Click action is executing successfully, the click event is not getting fired and the Select File Window is not invoked.

I am able to perform a "type" in the text box.However, the file is not uploaded by doing a type as your application does not support that.

2) Using the IE developer tool, it is highlighting the file object as below

Usually, to upload a file, the html input object used is of the "type=file" which I dont see in the above object.

Request you to have a word with your dev team and let us know if this object is a flash component (Notice the "type" attribute).

--------------------------------------------------------------------------------------------

can anybody please provide any input?

No data for some custom attributes on insert/edit

Hello,

I'm using the scheduler with a few custom attributes to handle some additional fields. Here's an example below.

When I perform the insert (the edit works the same way), I am handling the "AppointmentInsert" event and accessing the values with e.Appointment.Attributes("CustomAttribute").

For the AdminNotes and PublicNotes, this gets a value, for the AllocationGroupID and SlotCode, it just comes back as an empty string. Everything is otherwise identical and I can't figure it out here...

Anybody have any ideas?

Thanks,

Mike

Browser Compatability

Hello

Sorry if this is obviously available info elsewhere, but I checked the help docs and change logs and couln't see it.

Anyway, I'm (still!) stuck using an older version of the ASP.NET AJAX controls (2010 Q3 SP2), and was wondering what the officially supported browsers are/were. I'm guessing that it's simply the latest versions if IE amd Firefox as of the time, plus IE6, but just wanted to confirm?

If so, and for future reference, is that a general case -- that on release the supported versions of each browser are up to the latest version on release?

Cheers.

Client dataBind and repaint not working

Hi
I am using VS 2008 with your latest release and .net 3.5 and C#. I have a radgrid whith data columns defined using templates as follows:

<

telerik:GridTemplateColumn

<asp:Label ID="ShortActivityDescription"

runat="server"

Text='<%# Eval("ShortActivityDescription")%>'>

</asp:Label>

</ItemTemplate>

</telerik:GridTemplateColumn>

I originally load the grid (server side) during page load using the OnNeedDatasouce method defined in the RadGrid definition. Thereafter, I am using javascript and webservice(s) to do the insert, update, and delete logic and database IO. The webservice returns a list of data records to the calling javascript function. the successful completion method then does the following code (exactly like your demo example):

function Get_West_Activity_Grid_Complete(result)

{

if (result != null)

{

var tableView = $find("<%= Grid_West.ClientID %>").get_masterTableView();

tableView.set_dataSource(result);

tableView.dataBind();

var grid = $find("<%= Grid_West.ClientID %>");

grid.repaint();

}

The data gets added, changed, or deleted to/from the database but the grid does not refresh reflecting the changed data. The data properties in the web service result list contain the correct data and number of list objects are correct. The List properties identifiers(names) match the label id in the item template. The grid has the EnableAJAX property set to true.

I have researched the Forum material, user documentation and clientside api material and cannot see what I am doing wrong. I have read thru the following sources:

Grid / WebService Binding
Grid / .NET 3.5 Client-side Data Binding - automatic binding to WCF and ADO.NET services
Grid / Declarative Binding
Grid / Programmatic Binding
Grid / Client-side Binding and Caching

Please help

Weird RadGrid Error - Please help

I am getting an error that is just causing me all sorts of consternation finding a solution to. My code was working until I made some changes and posted it back onto the production server. The biggest problem here is that I don't get the error to occur on my dev machine so I can't use my debugger for any help.

I have an ASPX website with a Telerik RadGrid (version 2011.2.915.40) with another couple of RadGrids inside of the main

NestedViewTemplate.  I have checked all throughout my code looking for a place where this conversion from
nvarchar to int may be taking place yet i can't find it.  I don't understand why this error is occurring and 
would be most grateful to anyone that has run into something like this before and can give me a heads up
on what might be happening.  Please see error message below.

Thanks,

James
