RadFileExploerer deletes files on right-click (sometimes)

We are experiencing an issue where, when right clicking on a file in the RadFileExplorer, the file is sometimes deleted immediately. No confirmation dialog is displayed, as is usually the case when deleting files.

It only seems to happen in Safari and seems to happen intermittently. We have reproduced it on both Mac and Windows platforms.

I'm just wondering if this has been reported before or if you have any suggestions.

Any help you can offer will be appreciated.

Thanks

Export to Excel from RadGrid inside RadWindow

We have several pages where we have successfully exported RadGrid contents to Excel using the ExportToExcel() method. However, we now have a situation where we have a multi-page wizard using a MultiView controls and one of the View controls has a RadGrid on it with a preview of some results. The users would like to be able to export this RadGrid to Excel. However, the typical code does not work:

protected void ExportToExcelButton_Click(object sender, EventArgs e)
{
PreviewGrid.ExportSettings.IgnorePaging = true;
PreviewGrid.ExportSettings.OpenInNewWindow = true;
PreviewGrid.MasterTableView.ExportToExcel();
}

The RadGrid is fairly simple:

<telerik:RadGrid ID="PreviewGrid" AutoGenerateColumns="False"
OnNeedDataSource="PreviewGrid_NeedDataSource"
runat="server" Width="730px" Height="362px">
<ClientSettings>
<Selecting EnableDragToSelectRows="false"/>
<Scrolling AllowScroll="true" UseStaticHeaders="True"></Scrolling>
</ClientSettings>
<MasterTableView DataKeyNames="Key" NoMasterRecordsText="Nothing would be generated." CommandItemDisplay="Top" >
<CommandItemTemplate>
<div class="floatRightDiv" style="margin-top: 3px;margin-left: 700px;display:none;">
<asp:Button ID="ExportToExcelButton" runat="server" CssClass="rgExpXLS" OnClick="ExportToExcelButton_Click" Visible="false"/>
</div>
</CommandItemTemplate>
<Columns>
<telerik:GridBoundColumn UniqueName="Field1" DataField="Field1" HeaderText="Field1"></telerik:GridBoundColumn>
<telerik:GridBoundColumn UniqueName="Field2" DataField="Field2" HeaderText="Field2"></telerik:GridBoundColumn>
<telerik:GridBoundColumn UniqueName="Field3" DataField="Field3" HeaderText="Field3"></telerik:GridBoundColumn>
<telerik:GridBoundColumn UniqueName="Field4" DataField="Field4" HeaderText="Field4"></telerik:GridBoundColumn>
<telerik:GridBoundColumn UniqueName="Field5" DataField="Field5" HeaderText="Field5"></telerik:GridBoundColumn>
<telerik:GridBoundColumn UniqueName="Amount" DataField="Amount" HeaderText="Amount" DataFormatString="{0:N2}" ItemStyle-HorizontalAlign="Right" HeaderStyle-HorizontalAlign="Right"></telerik:GridBoundColumn>
</Columns>
</MasterTableView>
</telerik:RadGrid>

How can we export from a grid in a window?

Buttons overlapping

I'm having issues with the rad editor buttons overlapping at smaller window sizes. In attached image, look at the buttons to the right of the "Aa" button. Code is below.

                                            <telerik:RadEditor ID="rtbBannerHtml" runat="server"
                                                Skin="Silk"
                                                ToolbarMode="Default"
                                                Height="300px"
                                                Width="100%"
                                                ToolsFile="/ets/radcontrols/Editor/config/AdvancedBaseTools.xml"
                                                ShowSubmitCancelButtons="false">

HTML formatting issue with Editor

We have recently upgraded the telerik controls from v2010.2.1029.35 to v2014.3.1209.35. With old version, when we paste the HTML content shown below in the 'HTML' mode and then switch to the 'Design' mode, the editor removes the duplicate 'HEAD', 'TITLE', 'BODY' tags automatically. But when the same thing is done with the upgraded one, the editor removes all the content with the duplicate tags except the last one.

Any suggestion why it is behaving differently? Thanks in advance for the suggestions.

SelectedValue lost on postback in dynamically added user controls

We recently upgraded to the lates version of Telerik Ajax Controls (from 2010 Q2), and have an issue with the ComboBox.

We are dynaimcally loading user controls that contains comboboxes with autopostback set to true.
The problem is that the comboboxes selected values are lost on postback.

This works well when we use the old dll (2010 Q2).

I have tried the dll from Q3 2011 and i have the same problem with that.
Do you have any idea what would cause this?

Regards, Richard

No client data key names on masterTableView, cannot use getDataKeyValue()

I have my Radgrid defined with the master table in Batch mode as follows:

<telerik:RadGrid ID="EventSubjects" CssClass="eventSubjectsGrid" ShowStatusBar="true"

AutoGenerateColumns="False" GridLines="Both" AllowPaging="True"

PagerStyle-AlwaysVisible="true"

OnNeedDataSource="EventSubjects_NeedDataSource"

OnBatchEditCommand="EventSubjects_BatchEditCommand"

Skin="Sunset"

runat="server" GroupPanelPosition="Top">

<ClientSettings AllowKeyboardNavigation="true">

<Selecting AllowRowSelect="True" />

<ClientEvents OnCommand="gridCommand" />

</ClientSettings>

<ValidationSettings EnableValidation ="true" CommandsToValidate="PerformInsert,Update,UpdateEdited,saveChanges,BatchEdit"></ValidationSettings>

<MasterTableView EditMode="Batch" CommandItemDisplay="Bottom" DataKeyNames="PhotoSubjectID,EventPhotoSubjectID,EventPhotoSessionID">

<BatchEditingSettings EditType="Cell" />

In the ClientEvents OnCommand js function I am trying to the the Data Key for the current DataGridItem, but it comes back null (rowPhotoSessionID . When I check the masterTableView, masterTable.get_clientDataKeyNames(), it returns an empty array.

function gridCommand(sender, args) {

if (args.get_commandName() == "BatchEdit") {

var masterTable = sender.get_masterTableView();

var batchManager = sender.get_batchEditingManager();

var dataItems = masterTable.get_dataItems();

var validationFails = false;

for (var i = 0; i < dataItems.length; i++) {

var barcodeCell = dataItems[i].get_cell("Barcode");

var barcodeValue = batchManager.getCellValue(barcodeCell);

var rowPhotoSessionID = dataItems[i].getDataKeyValue("PhotoSubjectID");

.

.

How do I get the DataKeys for the current DataGridRow in this situation?

In case you are wondering, I am trying to do validation when the user clicks the 'Save Changes' button in BatchEdit mode, by passing the barcodes on the page to the server in an ajax call, and then update the cells that are invalid. So, I need both the barcode value and the PhotoSubjectID so that I can tell which barcodes changed.

I looked all over to find a property or method that would return me JUST the edited data values, I found this forum entry Batch Editing - Need to have the save changes button outside the grid , that said that this internal collection has the edited data, but did not recommend using it.

$find('RadGrid1').get_batchEditingManager()._changes

Is there some other way, in BatchEdit mode to get the edited values on the Client side so that I can do validation?

Row fields and user created GrandTotals ?

I have the need to either, create my own GrandTotal column to the right of the grid or .. allow me to show a PivotGridRowField to the right of the report.

Here are my fields (that are displayed as columns):

PivotGridColumnFIeld: Period

PivotGridAggregateFields: Plan, Actual

I want to add a column that is a percentage of Actual / Plan but I only want this column to show at the end in the GrandTotals section? Is there any way to do this?

Also, is there anyway to display PivotGridRowFields to the right of the GrandTotal columns?

Thanks,

PivotGrid
