scrollIntoView not working for TreeView in a ComboBox

I've got this as my code for the ComboBox opened client-side event...

function DropdownOpened(sender, e)

{

var treeView = sender.get_items().getItem(0).findControl("RadTreeView1");

treeView.get_element().focus();

var node = treeView.get_selectedNode();

if (node)

{

while (node.get_parent() && node.get_parent() instanceof Telerik.Web.UI.RadTreeNode)

{

node.set_expanded(true);

node = node.get_parent();

}

treeView.get_selectedNode().scrollIntoView();

}

The code works but the scrollIntoView call doesn't have any impact.

FWIW, I've tried wrapping the scrollIntoView call in a timeout call but to no avail.

Am I doing it wrong or are my expectations too high?

Problems with updating Scheduler on Calendar Change

Hi,

Just starting to use the scheduler and have tried to create a test program based on the 'overview' demo. This has a RadCalendar and a RadScheduler and it looks to be working correctly to start with but my problem is that when I click on a date in the calendar the scheduler is not refreshing to pick up the change. I have checked my code and other than changing the data source for the scheduler to read from an object list I cannot see what I have changed yet it doesn't work. I have checked that the OnCalendar1DateSelected event is being called when I click on the calendar and this is calling the set_selectedDate method of the scheduler but the scheduler itself stays on the original date. Any suggestions most welcome as I have been looking at this for a while now and cannot see why my test is different from the sample.

How to add new items to RadGrid in aspx from usercontrol asxc

Hi,

I am currently developing RadGrid control in the web form (aspx) and also develop usercontrol (asxc) which has RadTreeView and two buttons (Add and Cancel).

How can I add new items to the RadGridView in the web form when I checked some boxes of the treeview and then clicked "Add" button in the usercontrol?

I have source code below.

.ASPX

<telerik:RadGrid ID="rgRequestLocations" runat="server" CellSpacing="0" GridLines="None" AutoGenerateColumns="False"

OnNeedDataSource="rgRequestLocations_NeedDataSource" OnPreRender="rgRequestLocations_PreRender" OnItemInserted="rgRequestLocations_ItemInserted">

<MasterTableView InsertItemDisplay="Top" CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Add Locations to Request">

<NoRecordsTemplate>

<table>

<tr>

<td>

<asp:Label ID="lblNoRecords" runat="server" Style="color: red; font-weight: bold" TabIndex="14">You have not added any locations to the request.</asp:Label></td>

</tr>

</table>

</NoRecordsTemplate>

<Columns>

<telerik:GridEditCommandColumn UniqueName="EditCommandColumn">

</telerik:GridEditCommandColumn>

<telerik:GridBoundColumn SortExpression="location_pk" HeaderText="Location ID" HeaderButtonType="TextButton"

DataField="location_pk" Visible="false">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Location Name" HeaderButtonType="TextButton"

DataField="location_name">

</telerik:GridBoundColumn>

<telerik:GridEditCommandColumn ButtonType="PushButton" UniqueName="modify" EditText="Modify">

</telerik:GridEditCommandColumn>

<telerik:GridButtonColumn ButtonType="PushButton" CommandName="Delete" Text="Remove Location" UniqueName="removelocation">

</telerik:GridButtonColumn>

</Columns>

<EditFormSettings EditFormType="WebUserControl" UserControlName="~/Registration/Controls/PO_Registration.ascx">

<EditColumn UniqueName="EditCommandColumn1">

</EditColumn>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

In the Code-Behind of ASPX

protected void rgRequestLocations_ItemInserted(object sender, GridInsertedEventArgs e)

{

UserControl userControl = (UserControl)e.Item.FindControl(GridEditFormItem.EditFormUserControlID);

//insert a new values

Hashtable newVlaues = new Hashtable();

newVlaues["Grid"] = (userControl.FindControl("rtvlocation") as RadTreeView).GetAllNodes();

}

ASCX

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="PO_Registration.ascx.cs" Inherits="Registration_Controls_PO_Registration" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<div style="padding: 10px">

<telerik:RadDropDownList ID="ddlAdministrations" runat="server" AutoPostBack="true"

OnSelectedIndexChanged="ddlAdministrations_SelectedIndexChanged">

</telerik:RadDropDownList>

</div>

<div id="displayTreeViewAdmin" runat="server" visible="false" style="padding: 10px">

<div>

<telerik:RadTreeView ID="rtvLocations" runat="server" CheckBoxes="True"

CausesValidation="False" TriStateCheckBoxes="False" DataFieldID="location_pk"

DataFieldParentID="parent_fk" DataTextField="location_name" DataValueField="location_pk" />

</div>

<div style="padding: 10px">

<telerik:RadButton ID="btnAddLocations" runat="server" Text="Request Checked Locations" CommandName="Add" Visible='<%# !(DataItem is Telerik.Web.UI.GridInsertionObject) %>' OnClick="btnAddLocations_Click"></telerik:RadButton>

<telerik:RadButton ID="btnCancel" runat="server" Text="Cancel" OnClick="btnCancel_Click"></telerik:RadButton>

</div>

In the code-behind of Ascx

private object _dataItem = null;

public object DataItem

{

get

{

return this._dataItem;

}

set

{

this._dataItem = value;

}

#region Control Methods

override protected void OnInit(EventArgs e)

{

InitializeComponent();

base.OnInit(e);

}

private void InitializeComponent()

{

btnAddLocations.Visible = true;

PopulateAdminstrations();

}

#endregion

#region Button Events

protected void btnAddLocations_Click(object sender, EventArgs e)

{

/*loop through tree, create datatable with appropriate columns, and bind the datatable to radgrid*/

//create new properties

const string locationid = "location_id";

const string locationname = "location_name";

//initizlize new object of datatable level 1

DataTable dt = new DataTable();

dt.Clear();

//create a new colum for table level 1

DataColumn dcol = new DataColumn(locationid, typeof(System.Int32));

dt.Columns.Add(dcol);

dcol = new DataColumn(locationname, typeof(System.String));

dt.Columns.Add(dcol);

foreach (RadTreeNode row in rtvLocations.GetAllNodes())

{

if (row.Checkable)

{

if (row.Checked)

{

//Create a new row

DataRow drow = dt.NewRow();

drow[locationid] = row.Value;

drow[locationname] = row.Text;

//add row to the datatable

dt.Rows.Add(drow);

}

Session["RequestAdded"] = dt;

}

protected void btnCancel_Click(object sender, EventArgs e)

{

/*Close radgrid edit form*/

}

#endregion

Your help is very appericated very well.

Thanks,
