Hi,

I have seen this:

http://www.telerik.com/community/forums/aspnet-ajax/treeview/radtreeview-client-side-scrollintoview-for-selected-node-question.aspx

and this:

http://www.telerik.com/community/forums/aspnet-ajax/treeview/scrolling-to-last-expanded-node.aspx

However it doesnt achieve the results I need.

What is happening is that when I scroll all the way down the tree view and expand the last node (at the top level nodes) then it doesnt focus on the expanded children, I need to scroll down again to view the child nodes. What I want is for the childnodes to be shown upon expanding the parent node.

Using EditMode="Batch" does not work with Skin=""

I am trying to create a RadGrid which uses the batch edit mode feature but does not use any skin. When I change the Skin property from "Default" to "" the click to edit functionality stops working. I have been able to recreate the issue with a very basic example. Is this a known issue? Is there some sort of Skin="None" that I could use instead of an empty string?

Here is my ASPX

<telerik:RadGrid ID="RadGrid1" runat="server" Skin="" AutoGenerateColumns="False">

<MasterTableView CommandItemDisplay="TopAndBottom" EditMode="Batch" AutoGenerateColumns="False">

<BatchEditingSettings EditType="Cell" />

<Columns>

<telerik:GridBoundColumn DataField="Item1"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Item2"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

Here is my C#

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

List<Tuple<string, string>> source = new List<Tuple<string, string>>();

source.Add(new Tuple<string, string>("First Item", "Value1"));

source.Add(new Tuple<string, string>("Second Item", "Value 2"));

source.Add(new Tuple<string, string>("Third Item", "Value 3"));

RadGrid1.DataSource = source;

RadGrid1.DataBind();

}

Hyperlink Manager Error

Hi there,

We are using the RadEditor version 2008.1.515.20 in our application.

IE8: MultipleFileSelection and UploadedFilesRendering="BelowFileInput" Error

I'd been experiencing problems in IE8 when using multiple file selection, selecting >1 file in browser dialog and then immediately cancelling either uploadING files or files pending TO BE uploaded. IE would throw an exception detailed below which would then break client side scripting. The silverlight plugin is being used by IE.

After a lot of diagnosing I identified it to due to a possible bug caused by using multiple file selection with the UploadedFilesRendering="BelowFileInput" option on the control.

I managed to replicate this issue by testing the multiple selection example which initially had no issues cancelling files. Then when the UploadedFilesRendering="BelowFileInput" option is added cancels are broken as described (attached broken example for reference).

Please advise if there is any workaround for this issue as I still require the layout to be such that the uploaded files are listed below the file input. Thanks in advance.

IE exception:

Feature Request

Hi,

before the DropdownTree comes up, we used RadComboBox with embedded RadTreeView in the ItemTemplate.
In the Databindings of the RadTreeView there where some nice settings like this:

<DataBindings>

<telerik:RadTreeNodeBinding CheckedField="isChecked" Expanded="True" CheckableField="isSelectable" />

</DataBindings>

Would be nice to have this settings in the DropdownTree too.

Kind Regards

Thomas

Index Outside Bounds of Array

The rows in my grid need to be updated with the value of a checkbox. The rad dropdown gets a value, then based off of that value, the checkbox gets an assigned value of 'active'(checked) or 'not active'(unchecked). When the user clicks on 'Save', each checked box will then take the ID and associate it to the ID of the dropdown list. Debugging stops at the GridCommandItem line and throws the error `Index was outside the bounds of the array.` Can someone please help me out here? I don't work with arrays much so I don't know how to fix this.

PivotGridAggregateField with Calculated DataField

Hi:

I am trying to emulate a given Excel pivot table with the RadPivotGrid control. This pivot table has a calculated field used on the ‘∑ Values’ section with a ‘SUM’ aggregate function. I haven’t found a way to correctly set the PivotGridAggregateField tag. The formula for the calculated field is to divide other two fields, ex. field1/field2. What happens is that for each row Excel do: sum(field1) / sum(field2).

I am using ASP.NET 4.5, Windows 8, Internet Explorer 10.0.9200.16721, Telerik v.2013.2.717.45, C#.

The provided help will be appreciated.

Thanks!

Jose
