Table Properties in IE11 broken

The following problem happens when using IE11. I haven't been able to recreate the issue with Firefox and Chrome.

1. Use the Editor demo page and the HTML below.
2. Switch to design mode and right click either table...select table properties.

The version on your demo page currently places the edited table inside the table below it. I'm currently using version 2014.2.724.45...for me it deletes the table when the Table Properties dialog is closed.

This doesn't happen with all tables...and for the most part editing tables works as expected in IE11. The HTML below is an example of what can cause the problem.

<table style="width: 746px; height: 274px;">
<tbody>
<tr>
<td style="text-align: center; vertical-align: top;">

<a href="#0" tabindex="-1">
<img alt="" style="border-width: 3px; border-style: solid; margin-right: 0px; vertical-align: top;" src="0.jpg" />

Grid Batch Editing Problem IE9/8 with Readonly Field

Hello Folks,

we are having trouble with a specific constellation of the Grid Batch Edit Mode and Read Only Textfields (Gridbound Textcolumns).
Im blocking the Batcheditmode in the OnBatchEditOpening event and with modern browsers everything works as expected.

Though with IE 9 and IE 8 in Compatiblity Mode, we are having issues.

CSS wise, the fields are blocked and readonly, but unfortunatly the user is still able to enter text. Is there any known workaround?
The code is used in a SharePoint Webpart, hence changing the Documentmode is not a viable solution.

We are using the latest 2014 Release: 2014.3.1209.35

Asp Net TreeView

Hi,

I'm new to kendo and i was trying to display a treeView using the ASP MVC approach so i followed the exemple you provided :

var employees = from e in db.Employees
where (id.HasValue ? e.ReportsTo == id : e.ReportsTo == null)
select new
{
id = e.id,
Name = e.FirstName + " " + e.LastName,
hasChildren = e.Employees1.Any()
};

My question is: where the Employees1 comes from ? (I guess from the model) but what is the code inside this function ? where's the recursive function to loop on each child ? Can you provide the model and see what is inside ?

Thanks

TreeView

Nullable UInt32 From OpenAccessLinqDataSource Filtering Difficulties

I have an OpenAccessLinqDataSource that pulls from some FK linked tables. The FK value is nullable (UInt32?) and while sorting works, I'm having some difficulties filtering.

Here's my LinqDataSource

<telerik:OpenAccessLinqDataSource ID="OA_Promos" Runat="server" ContextTypeName="Flow.ST2_Data" EntityTypeName="" OrderBy="ID desc" ResourceSetName="Promos" Select=

"new (ID, identifier, descriptor, lastUpdated, notes, startDate, endDate, startTime, endTime, priority, Promo_art.Art, Promo_art.width, Promo_art.height, Promo_art.fileName, Promo_topic.SpotID)"

Where="Deleted == @Deleted" >

<WhereParameters>

<asp:Parameter DefaultValue="0" Name="Deleted" Type="Int16" />

</WhereParameters>

</telerik:OpenAccessLinqDataSource>

The Promo_topic.SpotID is the column I'm trying to filter on using the following:

<telerik:GridBoundColumn DataField="Promo_topic.SpotID" AllowFiltering="true" SortExpression="SpotID" CurrentFilterFunction="EqualTo" FilterControlAltText="Filter SpotID Column" AutoPostBackOnFilter="true" ShowFilterIcon="False" UniqueName="SpotID" HeaderText="Spot ID" DataType="System.UInt32"></telerik:GridBoundColumn>

but I get 0 results returned when I filter on a valid Promo_topic.SpotID

I tried custom filtering:

<telerik:GridBoundColumn DataField="Promo_topic.SpotID" AllowFiltering="true" SortExpression="SpotID" CurrentFilterFunction="Custom" FilterControlAltText="Filter SpotID Column" AutoPostBackOnFilter="true" ShowFilterIcon="False" UniqueName="SpotID" HeaderText="Spot ID" DataType="System.UInt32"></telerik:GridBoundColumn>

with the following ItemCommand event:

protected void ItemCommandFired(object sender, GridCommandEventArgs e)

{

if (e.CommandName == RadGrid.FilterCommandName)

{

Pair filterPair = (Pair)e.CommandArgument;

if (filterPair.First.ToString() == "Custom")

{

string colName = filterPair.Second.ToString();

TextBox tbPattern = (e.Item as GridFilteringItem)[colName].Controls[0] as TextBox;

e.Canceled = true;

grid_promos.MasterTableView.FilterExpression = string.Format("(Promo_topic.SpotID.Equals({0})) AND (Promo_topic.SpotID != null)", tbPattern.Text);

grid_promos.Rebind();

}

but then get the error "Methods on type 'UInt32?' are not accessible"

Before I switch the entire DataLinqSource to reference a custom object, is there something I'm doing wrong?

Thanks.

<br> tag added before with pasteHtml in chrome

Hi,

When adding content using pasteHtml method, it's adding <br> tag before the text in chrome browser due to which an extra line is appearing. This issue can also be reproduced using existing tool e.g. "Insert Time". The issue will be gone when you switch between HTML view and Design view. Check this screen cast: http://screencast.com/t/liOx9ryeIp1

Any work-around to fix this issue?

I'm using "ASP.NET AJAX Q2 2014" (2014.2.724.40) version.

Also I'm disabling ConvertToXhtml, ConvertCharactersToEntities, ConvertFontToSpan, and RemoveScripts filters. And NewLineMode = EditorNewLineModes.Div.

Thanks,
Anil

Control border colour via JQuery CSS

Hi,
I've got my drop down lists working with border coloured validation using JQuery. Now that I am trying to do the same thing with RadComboBoxes I can't seem to get the relevant css classes. Below is how I am doing this to the drop down lists. How do I do the same with ComboBoxes?

Regards

Jon

var $ = $telerik.$;

var dropDown = dropDownTree.get_element();

if (eventArgs.IsValid === false) {

$(dropDown).find(".rddtInner").addClass("RadDropDownTreeFieldErrorHighlight");

} else {

$(dropDown).find(".rddtInner").removeClass("RadDropDownTreeFieldErrorHighlight");

}
