Object reference not set to an instance of an object

I'm looking for a tool that enhances the RTE and found radEditor that looks like something what I need. So today I downloaded the zip 4.4.0 and tried to install it but failed directly.

Run:
stsadm -o addsolution -filename RadEditorMOSS.wsp

Got this message:
Object reference not set to an instance of an object.
RadEditorMOSS.wsp: The Solution installation failed.

Where do I look for a solution?

Cheers,
Klaus

RadConfirm then spinny

Hi Support,

In my application, I have a sequence where the following happens. The user clicks a button. A radconfirm message box containing a callback function executes which then potentially executes more code based on whether the user clicks OK or Cancel. If OK then more servier side code executes. If Cancel nothing more happens. This is all working fine with only one problem exists which I'm trying to remedy. The problem is I would like a "spinny" to work as the code executes since the code takes a long time to finish. To do this, I imagined I would put code that would ajaxify a panel containing an animated gif. For example(note, the Button is not shown):

Aspx

<asp:Panel ID="PanelLoadPlace" runat="server" style="padding-bottom:5px;">

<asp:Label ID="LabelSpacerForLoadingPanel" runat="server" Width="100px" Height="20px" />

</asp:Panel>

<telerik:RadAjaxLoadingPanel ID="panelLoading" runat="server" Style="margin-top: 0px;"

HorizontalAlign="center" IsSticky="false" Transparency="30" InitialDelayTime="100"

MinDisplayTime="500">

<asp:Image ID="ImageLoading" runat="server" ImageUrl="~/Images/loading.gif" BorderWidth="0px"

AlternateText="Loading..." />

</telerik:RadAjaxLoadingPanel>

C#

protected void Manager_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

RadAjaxManager

.GetCurrent(Page).AjaxSettings.AddAjaxSetting(Button, PanelLoadPlace, panelLoading);
}

However, this didn't work. I tried placing the above line AddAjaxSetting line immediately after the RadConfirm and that didn't work either. Any ideas?

RadGrid PagerItem Customization

Hi,

We are trying to use RadGrid to display results from SharePoint Search. We are using custom paging and getting only 10 pages at any time.

We tried using Custom paging for Radgrid to get correct total count and pager.

Paging for sharepoint behaves in a different way and we need to change URL for pager links to get it working.

Current URL for any pager item is similar to below:

javascript:__doPostBack('ctl00$m$g_97f5302f_eb53_4e7e_ad4d_174495682a37$ctl00$InvoicesGrid$ctl00$ctl03$ctl01$ctl05','')

We need to change it to something similar to below…

http://<sitename>/Sites/Search/Pages/results.aspx?k=ABC%3ALAB&start1=1

where start1 indicates the starting index of current page i.e PageSize * PageIndex + 1

Thanks.

Child nodes not inheriting parent checked value when load on demand

Hi,
I'm using a RadTreeView like this:

<

telerik:RadTreeView ID="WebTreeFolders"

runat="server"

Height="100%"

CheckBoxes="True"

CheckChildNodes="true"

PersistLoadOnDemandNodes="false"

EnableViewState="false" >

</telerik:RadTreeView>

The treeview loads child node when expanded using a static page method, and eveything works fine but the following scenario:
1) A node which NOT expanded is checked.
2) that node is then expanded.
3) Upon expand, the child nodes are populated using a web service method.
4) child node appear un-selected, although their parent node is selected.

How can I overcome this?

ConfirmText ignoring result

Hi,
I might be misunderstanding the use of ConfirmText on a GridButtonColumn, but if the user chooses "Cancel" then I would expect the ItemCommand event would not fire? We have a grid with a Delete button seen here

<telerik:GridButtonColumn Text="Delete" CommandName="Delete" ButtonType="ImageButton"

ConfirmText="Are you sure you want to delete this attachment?">

<HeaderStyle Width="20px" />

</telerik:GridButtonColumn>

The code for performing the delete occurs in the ItemCommand event. Unfortunately no matter what the user chooses (both Ok or Cancel) the event still fires performing the delete. Is this the correct behavior? If so, is there an argument I can grab from the GridCommandEventArgs to determine if the user select Ok or Cancel?

Thanks,
Mike

ListView Open RadWindow Code Behind Close Window Refresh Parent

I have a page with a RadListView Control:

<telerik:RadListView ID="rlv_Responses" runat="server" DataKeyNames="IDTicketsResponses"

DataSourceID="sds_Responses" Skin="WebBlue" BorderColor="#5A7594"

BorderStyle="Solid" BorderWidth="1px" Width="400px">

<div class="rlvA">

<table cellpadding="3" cellspacing="0"

style="border: thin solid #293852; padding: 10px; width: 100%">

<asp:Label ID="lbl_TicketsResponses1" runat="server"

Text='<%# Eval("IDTicketsResponses") %>' />

</div>

</SelectedItemTemplate>

</telerik:RadListView>

Because I need to get the value of the DataKey from the list view I need to open a RadWindow during the ItemCommand Event in the code behind:

Protected Sub RadListView1_ItemCommand(ByVal sender As Object, ByVal e As RadListViewCommandEventArgs) Handles rlv_Responses.ItemCommand

If e.CommandName = RadListView.SelectCommandName Then

Dim item As RadListViewDataItem = TryCast(e.ListViewItem, RadListViewDataItem)

Dim IDTicketsResponses As String = item.GetDataKeyValue("IDTicketsResponses").ToString()

Session("IDTicketsResponses") = IDTicketsResponses

Dim scriptstring As String = "radopen('helpdesk_tickets_respond_edit.aspx', 'EditResponse');"

RadAjaxManager1.ResponseScripts.Add(String.Format("refreshGrid('{0}')", "Server Response!"))

ScriptManager.RegisterStartupScript(Me, Me.[GetType](), "radopen", scriptstring, True)

End If

End Sub

Before adding the ListView control to the ASPX page, I used to open the window from the ASPX page using Java:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript" language="javascript">

function getQuerystring(key, default_) {

if (default_ == null) default_ = "";

key = key.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");

var regex = new RegExp("[\\?&]" + key + "=([^&#]*)");

var qs = regex.exec(window.location.href);

if (qs == null)

return default_;

else

return qs[1];

}

function AddResponse() {

var param1 = getQuerystring('IDTicket');

var param2 = getQuerystring('IDRequestor');

var oWnd = radopen("helpdesk_tickets_respond.aspx?IDTicket=" + param1 + "&IDRequestor=" + param2, "UserListDialog");

return false;

}

function refreshGrid(arg) {

if (!arg) {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

}

</script>

</telerik:RadCodeBlock>

And close the RadWindow that was opened with this Java:

<script type="text/javascript">

function Close(args) {

GetRadWindow().BrowserWindow.refreshGrid(args);

GetRadWindow().close();

}

function GetRadWindow() {

var oWindow = null;

if (window.radWindow) oWindow = window.radWindow; //Will work in Moz in all cases, including clasic dialog

else if (window.frameElement.radWindow) oWindow = window.frameElement.radWindow; //IE (and Moz as well)

return oWindow;

}

function CancelEdit() {

GetRadWindow().close();

}

</script>

When I used the ASPX page and java to open the window and then closed the window, the java did a great job of calling the RadAjaxManager and refreshing my ListView.

Now when I open the window from the VB code behind, the RadAjaxManager is no longer called when the pop up window is closed.

How can I ensure that the the RadAjaxManager fires when the pop up window closes even though the pop up is opened from the code behind?

I hope this was not TOO confusing. :)

Possible to have a RadGrid in a RadGrid?

Hi all,

I'm wondering if anyone knows if it's possible to have a RadGrid in RadGrid. Previously, I was able to do something similar where I had a DataList within a RadGrid column like so:

<telerik:GridTemplateColumn HeaderText="Keys" DataField="Keys">

<asp:DataList ID="DataList1" runat="server" DataSource='<%# Eval("Keys") %>'>

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Number") %>'></asp:Label>

</ItemTemplate>

</asp:DataList>

</ItemTemplate>

</telerik:GridTemplateColumn>

Note, in this code, I used data binding with the DataSource property in DataList. I was thinking I could so something similar with RadGrid. However, I just realized that RadGrid has no DataSource property.

Has anyone ever tried putting a RadGrid in a column in another RadGrid? Is there a way to do it, or is this a known limitation?

Jon
