<telerik:RadTreeView ID="RadTreeListUsers" runat="server" CheckBoxes="True" Width="585px" TriStateCheckBoxes="True" CheckChildNodes="True" meta:resourcekey="RadTreeListPermissionsResource1" />

var userValues = new HashSet<string>(users.Select(p => NodeValue.FormatTreeLabel(p.DataTypeName, p.ToDataTypeStateAutoId, p.ServiceAreaNum, p.OperationName, p.AttributeName)));

var userNodes = GetUserNodes(userValues);
RadTreeListUsers.Nodes.Clear();

RadGrid GroupByExpressions Sorting

Hi,

I have a RadGrid that gets its data from a stored procedure and the data is already ordered in the desired way. The RadGrid's group by automatically re-orders the group by field by alphabetical order. Is there a way to leave the order of the rows in its initial state? For example, if we're grouping on column X, if B appears before A from the data source, in the RadGrid B would be the first grouping section and A the second.

If not, then is there a way I can sort the group by field by a specific field? For example, this is what I would want to do:

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldName="Category" SortField="ColumnXYZ" SortOrder="Ascending" />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="Category" />

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

Thanks in advance!

Problems with create folder

When I create new folder I get an error

Error Message: Object reference not set to an instance of an object.
Stack Trace:
at Telerik.Web.UI.RadFileExplorer.CreateFolder(String currNodeValue, String newDirName)

This suggests the folder is not created.

However when I got to the server the folder has been created.

It is also there when I log back in.

What can I do to prevent this?

Is there a way to hide the possibility of adding and removing sheets?

We've been asked by our client to hide the workbook tabstrip buttons for adding and removing sheets.

We've searched all over but couldn't find a way to hide these buttons (the "+" and "x" buttons).

Any help would be most appreciated.

Find button on toolbar

Hello,
First I tried to access button by its index, i.e. toolbar.getAllItems()[3]. That worked for some time. But when 1st button is not a button but a dropdown with more buttons in it, that method returns wrong button. Next I tried to access buttons by value. That also worked for some time. But on buttons which may contain child items, like RadToolBarDropDown, that method won't work. Now what do I have to do? Search button by text? My buttons don't have a text at all. So what now?

PLEASE tell me is that a so HUGE problem do add a simple ID property to each button and implement FindButtonByID method? Is that a feature which requires a deep planning? You are developing this control so long and you can't implement this simplest feature? I can't believe that.

radeditor change font size, type, and color

In a vb.net 2010 web form application that I support, the application uses the Telerik Radeditor to edit letters sent to parents of students.
After the application runs, the html is stored in a SQL Server 2016 field called stringtemplate where the value is declared as varchar(max).
My question is I am trying to change the font size and color of the letters that are generated. When I look at the html that is stored in the stringtemplete field,
I do not see the html changes that I made.
Thus I am wondering if there is some part of the radeditor that I need to set so the font size and colors of parts of the letter can change. If so,
would you show me what I need to change?
