RadTextBox Mutliline

Dear Telerik-Support,

I use a lots of RadtextBoxes and some of these are used with Textmode="multiline".

With the new Q2 2012 release something strange occur. In EnableSingleInputRendering = fallse the text value of the textarea only disapear if I click into the textbox. If i set the text box to EnableSingleInputRendering = true everything is ok.

Unfortunalty currently I need the EnableSingleInputRendering = fallse behaviour.

I can't find a css problem but If i set the textmode other than multiline everything is ok in EnableSingleInputRendering = fallse.

Whats wrong here?

Kind reagrds,

Christian

Poor perfromance selecting row on scrollable grid

We are facing performance issues when selecting a row in a radgrid with nopaging and AllowScrrol = true.
Data bindng and scrolling performances are good, but when it comes to select a single row, the selection process takes 5 seconds for a 100 rows dataset and endless 15 seconds for a 600 rows dataset.
Don´t need to say that these times are unacceptable for a comercial web application.

I am trying to get these performance issues solved before getting into the keyboardnavigation problems.

What should I do to solve the selection poor performance?

TIA.

Binding to more than one table using TreeList

I am new to Telerik and I am trying to set up a TreeList that binds to an ObjectDataSource, which gets its data from LINQ. The primary LINQ entity is Matter; every matter has an associated Client record.

For the TreeList, Client would be the parent and Matter would be the child.

The problem is, Clients and Matters are in different tables. Can I build out a TreeList programatically like I can a TreeView with nodes? Is there an easier way?

The Client/Matter relationship is defined as an association in LINQ.

---UPDATE---

I've bound ListView to an ObjectDataSource that combines the two tables together. It isn't returning any data, however. Any idea what I am doing wrong? Again, Clients contain Matters. A record will be unique for each Matter but will contain non-unique data for its parent, Client.

<asp:ObjectDataSource ID="ClientMattersOds" runat="server" OldValuesParameterFormatString="original_{0}" SelectMethod="GetMattersBilledInPastYear" TypeName="Data.ClientMatter">

<SelectParameters>

<asp:Parameter Name="emplUno" Type="Int32" DefaultValue="66" />

</SelectParameters>

</asp:ObjectDataSource>

<telerik:RadTreeList ID="ClientsMattersTreeList" runat="server" DataKeyNames="MatterUno" ParentDataKeyNames="ClientUno" DataSourceID="ClientMattersOds"

PageSize="25" OnNeedDataSource="ClientsMattersTreeList_NeedDataSource" OnDataBound="ClientsMattersTreeList_DataBound">

<ExportSettings ExportMode="RemoveControls">

<Excel PageLeftMargin="0.7in" PageRightMargin="0.7in"></Excel>

<Pdf PageWidth="8.5in" PageHeight="11in"></Pdf>

</ExportSettings>

<EditFormSettings EditFormType="AutoGenerated">

<EditColumn MinWidth="" MaxWidth=""></EditColumn>

</EditFormSettings>

<Columns>

<telerik:TreeListBoundColumn DataField="CLIENT_UNO" DataType="System.Int16" MaxWidth="" MinWidth="" UniqueName="column">

</telerik:TreeListBoundColumn>

</Columns>

</telerik:RadTreeList>

[DataObjectMethod(DataObjectMethodType.Select, true)]

public static List<ClientMatter> GetMattersBilledInPastYear(int emplUno)

{

var dc = new Data.DdDataContext();

//Get the matters by searching all the time entries for this timekeeper from the past year

//Select only the resulting records that match records from this class

var records = dc.TimeEntries.Where(a => a.TK_EMPL_UNO == emplUno).Select(a => new ClientMatter()

{

_matter_Uno = a.MATTER_UNO,

_client_Uno = a.Matter.CLIENT_UNO,

_matter_Code = a.Matter.MATTER_CODE,

_client_Code = a.Matter.Client.CLIENT_CODE,

_matter_Name = a.Matter.MATTER_NAME,

_client_Name = a.Matter.Client.CLIENT_NAME

}).Distinct().ToList();

return records;

}

need your help with grid client api

okai i am following a tutorial on rad grid using hierarchies , so when on command event is triggered from the nested table i want to get a reference to the parent row that contains this nested table i am pasting the logic that is used in the tutorial , but its rather very complicated

function RadGrid2_Command(sender, args) {

   ordersView = sender.get_masterTableView();
    var nestedViewItem = sender.get_element().parentNode.parentNode;
    var parentGridDataItem = $find(Telerik.Web.UI.Grid.GetNodePreviousSiblingByTagName(nestedViewItem, "tr").id);
    var customerID = parentGridDataItem.getDataKeyValue("CustomerID");

    args.set_cancel(true);

    ordersCommandName = args.get_commandName();

    WebService.GetOrdersByCustomerID(customerID, ordersView.get_currentPageIndex() * ordersView.get_pageSize(), ordersView.get_pageSize(),
                    ordersView.get_sortExpressions().toString(), ordersView.get_filterExpressions().toDynamicLinq(),
                        updateOrdersGrid);
}

but why cant i use
   var c = sender.get_masterTableView().get_parentRow();
method ?, its returning null when i use it in the on command event , and if any one of you can please explain me the logic behind the on command event that i have pasted , i will be much grateful!!!

GridBoundColumn GroupByExpression format string

Is it possible to use a format string for a column? I saw a similar post here about formatting the text in the GroupByExpression for the column but it doesn't seem to work correctly.

Is this on the TODO list or anything? I'm still using Q3 2011 Ajax controls so if its been added to the latest ones, let me know.
