How can I get the mouse event object if I attach the client event inline?

<telerik:RadButton runat="server" ID="testButton" OnClientClick="onclicktestbutton" />
<script type="text/javascript">
function onclicktestbutton(sender, args) {
// I don't use window.event (it is non-standard)
}
</script>

Where can I set the event object??
I wanted to do it like this:

<telerik:RadButton runat="server" ID="testButton" OnClientClick="onclicktestbutton(event)" />

but we all know you can't insert paragraph on a telerik client event attribute because it automatically includes in the function the parameters (sender, args).

I don't want to export Hierarchical Grid Rows that have no child records.

Hi,

I am using version 2015.1.401.40 of the ASP.NET controls for AJAX.

I would think my question would be very common and easy to do.

I have a RadGrid with a MasterTableView and 1 DetailTable (GridTableView). I am using NeedDataSource for binding and it is all working fine.

Not all records in the master, have child records. For the rows that do not, I have hidden the expand/collapse button in the DetailTableDataBind event.

When I export to Excel, I want to expand all rows that contain a child record, so that those rows get exported. I was doing that in DetailTableDataBind by setting every GridDataItem .Expanded = True.

ISSUE:

The problem with this is that it expands and exports the child rows that say "No Child Records".

Question: How can I NOT have it export the gridtableview, if there are no child records?

In the DetailTableDataBind, if there are no child records I set the DetailTableView.Visible = False, but my export still contains a blank row (which is better than the "No Child Records", but not perfect).

Thanks,
Brent

Open custom dialog from RadWindow

Hi all,

I have an editable grid. When row is edited new RadWindow is opened. User can make some changes and after pressing save some serve-side code is executed. When specific conditions are met I want user response to continue correctly. I am using RadWindowManager and method RadConfirm for user response. It worked fine, but I need more possibilities now and I want to put 4 buttons instead of Ok/Cancel.

So I created new window DialogDeleteConfirm on my page



<telerik:RadWindowManager ID="radWindowManager1" runat="server" ViewStateMode="Disabled" >
  <Windows>
    <telerik:RadWindow ID="RadWindow1" runat="server" ShowContentDuringLoad="false" DestroyOnClose="false" ViewStateMode="Disabled" KeepInScreenBounds="true"
      VisibleStatusbar="false"  Modal="True"  >
    </telerik:RadWindow>
    <telerik:RadWindow ID="DialogDeleteConfirm" runat="server" Width="450px" Height="120px" Modal="true">
        <ContentTemplate>
          <div style="padding: 10px; text-align: center;">
            <p style="text-align: center;">Do you want to delete items automatically?</p>
            <asp:Button ID="btnOk" runat="server" OnClientClick="returnArg('O'); return false;" />
            <asp:Button ID="btnSelection" runat="server" OnClientClick="returnArg('S'); return false;" />
            <asp:Button ID="btnKeepAll" runat="server" OnClientClick="returnArg('K'); return false;" />
            <asp:Button ID="btnCancel" runat="server" OnClientClick="returnArg('C'); return false;" />
          </div>
        </ContentTemplate>
    </telerik:RadWindow>
  </Windows>
</telerik:RadWindowManager>

According another discussion I simply replace my existing code

radWindowManager1.RadConfirm(messageToUser, "autoDeleteCallback", 450, 120, null, "");

by

DialogDeleteConfirm.VisibleOnPageLoad = true;

But it doesn't work and no window is displayed. Unfortunately there is no method in RadWindowManager to open window.

Can you help me how to open new window immediately?

Thanks a lot,
Petr

Could not load type 'Telerik.Web.Examples.Scheduler.ExchangeSchedulerProvider'

Hello,

I have installed the RadControls trial version and the sample ScheduleBuilder (that is the only sample that I have installed). The sample is in C# and in the header of the Default.aspx sample, it contains:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

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

My reason for pointing this out is because on your webpage Scheduler / Binding to Generic List, the VB example contains several additional lines of script between the <%@ Page... line and the <!DOCTYPE.... line (as follows):

<%@ Page Language="VB" AutoEventWireup="true" CodeFile="Default.aspx.vb"

Inherits="Telerik.Web.Examples.Scheduler.BindToList.DefaultVB" %>
<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>
<%@ Register TagPrefix="qsf" Namespace="Telerik.QuickStart" %>
<%@ Register TagPrefix="qsf" TagName="Header" Src="~/Common/Header.ascx" %>
<%@ Register TagPrefix="qsf" TagName="HeadTag" Src="~/Common/HeadTag.ascx" %>
<%@ Register TagPrefix="qsf" TagName="Footer" Src="~/Common/Footer.ascx" %>
<%@ Register TagPrefix="sds" Namespace="Telerik.Web.SessionDS" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/tr/xhtml11/dtd/xhtml11.dtd">

I'm not sure if this has anything to do with my issue, so I want to point out this difference between the VB and C# examples.

The ScheduleBuilder sample has, but default, connection strings for SQL Server. I am trying to replace those connections with a connector to my Exchange data store. That is possible, right?

I am using Visual Studio 2010 and Exchange Server 2010. These are 2 different machines. The sample ScheduleBuilder is running from the VS2010 machine and attempting to connect to the Exchange server machine (both machines are in the same network).

I modified the Web.config that is included with the sample. Under the <configuration> node of the Web.Config, I added:

<

configuration>

</sectionGroup>

</configSections>

<telerik.web.ui>

</appointmentProviders>

</radScheduler>

</telerik.web.ui>

.

</configuration>

In addition, I went to the Default.aspx script and along with the attributes already assigned to telerik:RadScheduler, I added attribute:

ProviderName="ExchangeSchedulerProvider"

The sample project compiles clean, but when I try to view Default.aspx, the browser displays:

Server Error in '/ScheduleBuilder.Web' Application.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Could not load type 'Telerik.Web.Examples.Scheduler.ExchangeSchedulerProvider'.

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.225

Using the serverURL that you see above, I can successfully add a Web Reference to https://myExchSvr.myDomain.com/EWS/Services.wsdl, and when adding the reference, I was prompted for credentials, so I used the same username and password specified in the Web.Config. I was able to successfully add a reference to Services.wsdl. Therefore I am assuming that I should have access to Exchange.asmx as well.

The error that I am encountering does not appear to be a server-side issue, but it appears that maybe the ExchangeScheduleProvider did not properly register when installed on the VS2010 machine??? Regardless, I did test with Anonymous access both enabled and disabled on the EWS virtual (Exchange Server machine), but the same error occurs.

I believe I am overlooking something obvious, but don't know what, and I have been trying to resolve this for several hours now. My boss wants me to prove that this control will be able to read/write appointments directly from/to an Exchange data store before he will buy this product. And I would like to prove that this radControl will work so that I don't have to design something from scratch.

How do I resolve this problem?

Thank you,
Steven

Loading items from WebService

I have a textbox and a listbox that displays customer information. On page load my listbox populates just fine from a webmethod and shows in a ClientItemTemplate. I want to be able to call this webmethod from code-behind and repopulate the listbox based on what text is typed in the textbox (onkeyup). The problem is I keep getting the error "JavaScript runtime error: Object doesn't support property or method 'get_parent'"

Here is the server-side code:

<WebMethod()> _

Public Shared Function GetCustomers() As RadListBoxItemData()

Dim data As DataTable = GetData("248")

Dim result As New List(Of RadListBoxItemData)()

For i As Integer = 0 To data.Rows.Count - 1

Dim itemData As New RadListBoxItemData()

Dim FullName As String = data.Rows(i)("FName").ToString() & " " & data.Rows(i)("LName").ToString()

itemData.Text = data.Rows(i)("CPhone").ToString()

itemData.Value = data.Rows(i)("CPhone").ToString()

itemData.Attributes.Add("FullName", FullName)

itemData.Attributes.Add("Phone", data.Rows(i)("CPhone").ToString().Insert(0, "(").Insert(4, ") ").Insert(9, "-"))

'--Determine opt-in icon

Select Case data.Rows(i)("OptIn").ToString()

Case -1

itemData.Attributes.Add("OptIn", "<img alt='Opted-In' src='images_zw/OptIn_OptedIn.png' />")

Case 0

itemData.Attributes.Add("OptIn", "<img alt='Blocked / Opted-Out' src='images_zw/OptIn_Blocked.png' />")

Case 1

itemData.Attributes.Add("OptIn", "<img alt='Pending Opt-In' src='images_zw/OptIn_Pending.png' />")

Case 2

itemData.Attributes.Add("OptIn", "")

End Select

result.Add(itemData)

Next

Return result.ToArray()

End Function

Here is my client-side code:

<script type="text/javascript">

function Generate()

{

var listbox = $find("<%= lstContacts.ClientID%>");

var result = PageMethods.GetCustomers(function (response) {

response.forEach(function (listitem) {

listbox.trackChanges();

listbox.get_items().add(listitem);

listbox.commitChanges();

});

//listbox.insertItems(response);

});

}

</script>

<div>

<div><telerik:RadTextBox runat="server" id="txtSearch" AutoPostBack="False" onkeyup="Generate();" Text="248"></telerik:RadTextBox></div>

<div>

<telerik:RadListBox runat="server" ID="lstContacts" width="300" height="500" AutoPostBack="False">

<ClientItemTemplate>

<div class="Search_Conversation_Container">

<div class="Search_OptIn">

#= Text #

</div>

</ClientItemTemplate>

<WebServiceSettings Path="testlist.aspx" Method="GetCustomers"></WebServiceSettings>

</telerik:RadListBox>

</div>

RadComboBox remove all items and repopulate

I have two related RadComboBoxes as following:

<div class="subv"><telerik:RadCodeBlock ID="RadCodeBlock2" runat="server"> <%= SelectedSitesText %></telerik:RadCodeBlock></div>

</div>

What i am trying to achieve is to have the second comboBox (RadComboBoxSites) populated upon selected Values of first comboBox.

Tried to achive that by deleting all items of RadComboBoxSites each time a SelectedIndexChanged event is occured on comboBox RadComboBoxCountries in the way depicted below:

Protected Sub RadComboBoxCountries_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)

If (RadDropDownParameterX.SelectedValue.Equals("Sites"))

Dim collectionPopulatedSites = RadComboBoxSites.Items

For each s In collectionPopulatedSites

Dim RadComboBoxSite As RadComboBoxItem = RadComboBoxSites.Items.FindItemByValue(s.Value)

If RadComboBoxSite IsNot Nothing Then

RadComboBoxSite.Remove

End If

Next

' get new list of selected countries

Dim collectionSelectedCountries = RadComboBoxCountries.CheckedItems

For each c in collectionSelectedCountries

Dim listaCountrySites As List(Of AffideaGeneralWeb.BLL.General.Sites)

listaCountrySites = GetAllCountrySites(c.Value)

For each s in listaCountrySites

Dim RadComboBoxSite As RadComboBoxItem = RadComboBoxSites.Items.FindItemByValue(s.ID)

If RadComboBoxSite Is Nothing Then

RadComboBoxSite = New RadComboBoxItem()

RadComboBoxSite.Text = s.Title

RadComboBoxSite.Value = s.ID

RadComboBoxSites.Items.Add(RadComboBoxSite)

End If

Next

End If

End Sub

However when i am trying to "RadComboBoxSite.Remove" i am getting an exception:

An exception of type 'System.InvalidOperationException' occurred in mscorlib.dll but was not handled in user code. Additional information: The collection has changed, the enumeration operation may not be performed

Is there any working example of related comboBoxes (handles in the server side)?

How could i delete all items of second comboBox and re-build it, each time the user alters selection on the first comboBox?
