Error combining CheckBoxes, AutoPostBack and EnableVirtualScrolling

I have this ASPX code:

<telerik:RadComboBox runat="server" ID="instituicao" Width="450" CheckBoxes="true"

AutoPostBack="true" ItemsPerRequest="10"

EnableLoadOnDemand="True" ShowMoreResultsBox="true" EnableVirtualScrolling="true"

OnItemChecked="instituicao_ItemChecked" OnItemsRequested="instituicao_ItemsRequested" />

And this code behind:

protected void instituicao_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)

{

DataTable dt = GetData();

int total = dt.Rows.Count;

int itemOffset = e.NumberOfItems;

int endOffset = Math.Min(itemOffset + instituicao.ItemsPerRequest, total);

e.EndOfItems = endOffset == total;

instituicao.Items.AddRange(

dt.Rows.OfType<DataRow>().Skip(itemOffset).Take(endOffset - itemOffset)

.Select(i => new RadComboBoxItem(i["Id"] as string, i["Id"] as string)));

}

protected void instituicao_ItemChecked(object sender, RadComboBoxItemEventArgs e)

{

// do stuff

}

private DataTable GetData()

{

DataTable dt = new DataTable();

dt.Columns.Add("Id", typeof(string));

for (int i = 1; i <= 100; i++ )

{

DataRow row = dt.NewRow();

row["Id"] = i;

dt.Rows.Add(row);

}

return dt;

}

When I check an item I got this error and my code is never executed:

[ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index]

System.Collections.ArrayList.get_Item(Int32 index) +7487944

System.Web.UI.StateManagedCollection.System.Collections.IList.get_Item(Int32 index) +12

Telerik.Web.UI.ControlItemCollection.get_Item(Int32 index) +48

Telerik.Web.UI.RadComboBoxItemCollection.get_Item(Int32 index) +37

Telerik.Web.UI.RadComboBox.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +238

System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13

System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175

System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

Any clues?

Problem with editor menus when scrolling Firefox

We're having a problem accessing context and toolbar menus in the Editor using Firefox when the browser page has been scrolled. No problem with IE.

I'll include a link to a short video demonstrating the problem. You'll see that once the browser has been scrolled, the context and toolbar menus appear in different positions, and clicking an item on the menu has no effect; the menu disappears on mousedown. Once the browser page is scrolled back to the default position, the menus become functional again.

The problem seems to have manifest after upgrading the site to .NET 4.0.

The version of Telerik.Web.UI.dll is 2009.2.701.20. I realize this is not the current version of the editor and upgrading is in our near future, however, this problem has to be resolved immediately. Any help would be appreciated.

Source File: http://localhost:6444/CJIS/Pretrial/Lookup.aspx?NewInterview=2034111
Line: 164

However, again, it works fine in IE and Chrome.

Any suggestions? Thanks!

Performance Problems with RadGrid in IE8

I have a client-side performance problem in IE8 with RadGrid. The grid has only 150 rows and looks like this:

<telerik:grid runat="server" ID="rgArtikel" AllowSorting="false" AllowFilteringByColumn="false"

AutoGenerateColumns="false" EnableAjaxSkinRendering="false" EnableViewState="true"

Visible="true" OnNeedDataSource="rgArtikel_NeedDataSource" OnItemDataBound="rgArtikel_ItemDataBound">

<ClientSettings AllowKeyboardNavigation="true" EnablePostBackOnRowClick="false">

<Selecting AllowRowSelect="false" />

</ClientSettings>

<MasterTableView AllowFilteringByColumn="false">

<Columns>

<telerik:GridTemplateColumn UniqueName="Key" InitializeTemplatesFirst="false" HeaderText="">

<ItemTemplate>

<asp:Literal ID="lKey" runat="server" Visible="false"></asp:Literal>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="Icon1" InitializeTemplatesFirst="false" HeaderText="Leit.">

<ItemTemplate>

<asp:Image ID="iLeitArtikel" runat="server" Visible="false"></asp:Image>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="Icon2" InitializeTemplatesFirst="false" HeaderText="Info">

<ItemTemplate>

<asp:Image ID="iArtikel" runat="server" Visible="false"></asp:Image>

<uc1:RDisplayArtikel ID="RDisplayArtikel" runat="server" Visible="false" />

<uc2:RSammelArtikel ID="RSammelArtikel" runat="server" Visible="false" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="Icon3" InitializeTemplatesFirst="false" HeaderText="">

<ItemTemplate>

<asp:Image ID="iPfand" runat="server" Visible="false"></asp:Image>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="Akt.VKP" InitializeTemplatesFirst="true"

HeaderText="Aktions-VKP">

<ItemTemplate>

<telerik:RadNumericTextBox ID="tbAktVkp" runat="server" Width="50px" Height="10px"

Type="Currency" DecimalSeparator="," Visible="false" Editable="Editable" MinValue="0">

<ClientEvents OnValueChanged="setChanged" />

</telerik:RadNumericTextBox>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="Aktionen" InitializeTemplatesFirst="false"

HeaderText="">

<ItemTemplate>

<asp:Image runat="server" ID="iAktionen" Visible="false"></asp:Image>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="iBeschaffung" InitializeTemplatesFirst="false"

HeaderText="">

<ItemTemplate>

<asp:HyperLink ID="iBeschaffung" runat="server" Visible="false" ToolTip="Beschaffungsregel vorhanden"></asp:HyperLink>

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</tegut:XYGrid>

The grid is filled in backend with max. 150 rows und is rendered fast. But when the site is shown in IE8, the CPU-Load is up to 100% and the IE doesn't react for about 3s. If I allow scrolling and enable fixed header, the IE stops working for about 5s.

Is there any trick to speed this up ?? I think 150 is not a large number of rows the grid can't handel anymore.

And by the way another problem: the resizing didn't work proper with scrolling enabled too. It's getting only larger not smaller (smallest size is size on load)!

Issue Adding Button in Sitecore 6.4

Hello,

I am trying to add a button to a RadEditor in Sitecore 6.4 that will open up a dialog when clicked. The button is displaying correctly, but I get an error when the button is clicked. An alert pops up saying "The command EmbedBrightcoveVideo is not implemented yet."

I have added the following code to /sitecore/shell/Controls/Rich Text Editor/RichText Commands.js, which is what I thought was all I had to do to get it to work...

RadEditorCommandList["EmbedBrightcoveVideo"] = function(commandName, editor, tool) {

alert('EmbedBrightcoveVideo fired.');

}

The JavaScript never fires. I don't seem to be getting any JavaScript errors either. Any ideas as to what could be wrong?

Thanks a lot.

Toolbar Mode - Floating - Default On

Hi,
We're using Telerik RAD Editor for MOSS version 8.5.0.0 and we have a slight question on the toolbar mode 'Floating'.

1. Can you tell me if there is an option to have the tool bar appear by default instead of clicking on the icon to turn the toolbars on each time?
2. Can you tell me if there is an option to set the default option on the 'pin' to lock the floating toolbar in position, to 'On'?

Thanks,
Jason.
