Dear All,

Please let me know if its possible to open RadWindow using severside code from Application_start event of Global.asax. I am trying to open the radwindow in a callback method of cache item whenever the cache item expires. Please find the code below for your reference. Any help will be appreciated.

Regards,
Noor Hussain

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)

' Fires when the application is started

RegisterCacheEntry()

End Sub

''' <summary>

''' Register a cache entry which expires in 1 minute and gives us a callback.

''' </summary>

''' <remarks></remarks>

Private Sub RegisterCacheEntry()

' Prevent duplicate key addition

If HttpContext.Current.Cache(DummyCacheItemKey) IsNot Nothing Then

Return

End If

HttpContext.Current.Cache.Add(DummyCacheItemKey, "Test", Nothing, DateTime.MaxValue, TimeSpan.FromMinutes(1), CacheItemPriority.NotRemovable, _

New CacheItemRemovedCallback(AddressOf CacheItemRemovedCallback))

End Sub

''' <summary>

''' Callback method which gets invoked whenever the cache entry expires.

''' We can do our "service" works here.

''' </summary>

''' <param name="key"></param>

''' <param name="value"></param>

''' <param name="reason"></param>

Public Sub CacheItemRemovedCallback(ByVal key As String, ByVal value As Object, ByVal reason As CacheItemRemovedReason)

Debug.WriteLine("Cache item callback: " & DateTime.Now.ToString())

' Do the service works

DoWork()

' We need to register another cache item which will expire again in one

' minute. However, as this callback occurs without any HttpContext, we do not

' have access to HttpContext and thus cannot access the Cache object. The

' only way we can access HttpContext is when a request is being processed which

' means a webpage is hit. So, we need to simulate a web page hit and then

' add the cache item.

HitPage()

End Sub

''' <summary>

''' Hits a local webpage in order to add another expiring item in cache

''' </summary>

Private Sub HitPage()

Dim client As New WebClient()

Format and export telephone number (stored in DB as string) from RadGrid to excel.

Hi,

I have a column field in SQL Server database which is a string file, which contain phone number (11 digits, for example: 12223334444). In RadGrid, I used following code to format the number to display in RadGrid as a proper telephone number:

protected void RadGridResult_ItemDataBound(object sender, GridItemEventArgs e)

{

//Format string to phone number.

if (e.Item is GridDataItem)

{

GridDataItem item = (GridDataItem) e.Item;

Object ob = item["ConfirmationLogPhone"].Text;

if (!Convert.IsDBNull(ob))

{

Int64 iParsedValue = 0;

if (Int64.TryParse(ob.ToString(), out iParsedValue))

{

TableCell cell = item["ConfirmationLogPhone"];

cell.Text =

String.Format(System.Globalization.CultureInfo.CurrentCulture, "{0:#-(###) ###-####}", new object[] { iParsedValue });

}

However, when I export the grid to excel, the number is display merely just a string (Ex: 12223334444). MS Excel even report error that "Number stored as text field" on every cell in the column.

Would you please tell me how to format and export string of telephone number to excel properly?

Thanks

RadListBoxes with AllowTransfer - need to access transfer items server side

I have an aspx page with 2 RadListBox controls. AllowTransfer = true for RadListBox1. RadListBox1 gets populated from a database and is also tied to a TextBox used as a filter.

After transfering items from RadListBox1 to RadListBox2 by clicking the client-side arrow button that gets displayed with RadListBox1 I can see the items on the client side of RadListBox2. but these items are not accessible on the server side.

I need to get server-side access the new items in RadListbox2 during a postback in order to pass them to another method ... but the server-side items colleciton is empty.

Setting a breakpont I do see a value in RadListBox2.ClientChanges ... and an array like this:

>? RadListBox2.ClientChanges

Count = 2

[0]: {Telerik.Web.UI.ClientOperation<Telerik.Web.UI.RadListBoxItem>}

[1]: {Telerik.Web.UI.ClientOperation<Telerik.Web.UI.RadListBoxItem>}

Is there a way to access these items in a server side postback? Thanks

Button cannot be disabled from client side

Hi,

I am trying to disable a submit button from the client side. I am using the following code:

function OkClicked(sender, args) {

document.getElementById("<%=btnConfirm.ClientID %>").set_enabled(false);

}

This is the markup for the button:

<telerik:RadButton ID="btnConfirm" runat="server" OnClick="btnConfirm_Click" Enabled="true">

<Icon SecondaryIconCssClass="rbOk" SecondaryIconRight="4" SecondaryIconTop="4" />

</telerik:RadButton>

When the button gets clicked it deosn't get disabled, but does a postback.I also tried the following script:

document.getElementById("<%=btnConfirm.ClientID %>").disabled = true;

In this case the button APPEARS disabled, but still responds to clicks and any other events (like hover).

What's going on here?

RadPanelBar and SPDataSource

I've followed the example at http://demos.telerik.com/aspnet-ajax/panelbar/examples/populatingwithdata/databindings/defaultvb.aspx to add a RadPanelBar and RadPanelItems to a SharePoint 2010 page without any success. The RadPanelBar doesn't show on the page when I give values to DataFieldID & DataFieldParentID. No error given. When I leave those properties blank and set DataTextField="Title" then I get the menu but only the 1st level.

Instead of an SQLDataSource I'm using an SPDataSource. The spdatasource does work however, with an asp:DropDownList control.

Are there issues with RadpanelBar and SPDataSource?

TabStrip Validation

Hello,

I have a tab strip of five tabs, each has a user control dynamically loaded into a corresponding multi page. Each of the user control's has it's own validation, and when I click a button that causes validation, I only want it to validate that particular user control, with javascript. Everything is set up properly as far as the validation controls, but every tab validates when I only want the currently selected tab to validate. Can anyone help me on this?

RadTreeView problem in Fieldset

Hey guys...hope you can help with this one.

I've got a RadTreeView control inside a fieldset. For the purposes of this request I cannot change how the project is organized :) The problem is, in IE only of course, the TreeView overlaps content below the fieldset as it is expanded (image attached).

This problem goes away if I remove the fieldset! Is there any redraw or refresh events that I can trigger on the TreeView that will solve this issue?

Occurs in IE8 in both regular and compatibility modes.

Words added to .TDF not shown in suggestions

Hello,

I've added 9900 + words to the default .TDF dictionary file using the Dictionary Configurator downloaded from another forum here at Telerik.

While testing some of the words, all medical in nature, I don't seem to have consistent suggestions.

For example I enter zygapophy and I should get zygapophyseal, zygapophyses, and zygapophysis as suggestions but I only receive the last two. In my dictionary I have the following entries:

zygapophyses:SKPF:SKPF
zygapophysis:SKPF:SKPF
zygapophyseal:SKPF:SKPF

I have a total of 159,596 words in the default .TDF file. Using the Custom Dictionary is not an option because of my security/network set up.

I loaded a list of words into a word document with a .TXT extension then used the Dictionary Configurator to load all of them to the existing .TDF list - this was successful. I used the DC to test this same scenario and it works perfectly but in my application I'm experiencing the issue I stated above - missing zygapophyseal from the suggestion list.

I assume the spell checker uses the second and third columns to help group words for the suggestion list, but in this case it seems not to work correctly.

Have any ideas/suggestions?

Thanks in advance,

Dan

PS. I'm using VS.Net 2008 and C#
