How to handle TreeView ClientSide data binding with WebService

<telerik:RadTreeView ID="rtvResources" runat="server" OnClientNodeClicked="rtvResources_OnClientNodeClicked"

OnClientContextMenuItemClicking="rtvResources_OnClientContextMenuItemClicking"

OnClientContextMenuShowing="rtvResources_OnClientContextMenuShowing" OnClientNodePopulationFailed="function(o,e){}" >

<Nodes>

<telerik:RadTreeNode runat="server" Text="Public" AllowDrop="false" CssClass="PUBLIC"

ImageUrl="~/Images/folder-icon.png" Selected="true">

</telerik:RadTreeNode>

<telerik:RadTreeNode runat="server" Text="My Resources" AllowDrop="false" CssClass="USER"

ImageUrl="~/Images/folder-icon.png">

</telerik:RadTreeNode>

<telerik:RadTreeNode runat="server" Text="Search Folders" AllowDrop="false" CssClass="SEARCH"

ImageUrl="~/Images/search-folder-icon.png" Value="SEARCH">

</telerik:RadTreeNode>

</Nodes>

<ClientNodeTemplate><span id="#=Value#_span">#=Text#</span> <input type="text" value="#=Text#" style="display:none;width:100px;" id="#=Value#_txtEdit" onblur="javascript:Rename();"></input>

</ClientNodeTemplate>

<WebServiceSettings Path="ManageResources.aspx" Method="wmGetResources" />

</telerik:RadTreeView>

This is working fine .
But if I get exception in webservice it throws exption message using alert popup.
I try to handle with OnClientNodePopulationFailed="function(o,e){}" but still it shows expetion message in window .Please provide way to handle it.

Thanks ,
Somnath

Modifying GridDateTimeColumnEditor timeview

I currently have a GridDateTimeColumn with PickerType = DateTimePicker. I want to change the timeview to display in 2 columns instead of the default 3. I've searched the forums and found what I thought should be solutions but the code seems to have no effect.
(http://www.telerik.com/community/forums/aspnet-ajax/grid/many-grid-questions.aspx ; http://www.telerik.com/community/forums/aspnet-ajax/grid/how-to-localize-datetimepicker-s-tooltip-in-filter-menu.aspx )

In the RadGrid1_ItemDataBound event I have the following code:

GridEditableItem item = (GridEditableItem)e.Item;

RadDateTimePicker expiresTimePicker = (RadDateTimePicker)item["Expires"].Controls[0];

expiresTimePicker.TimeView.Columns = 2;

GridDateTimeColumnEditor colEd = (item.EditManager.GetColumnEditor("Expires") as GridDateTimeColumnEditor);

(colEd.PickerControl as RadDateTimePicker).TimeView.Columns = 2;

The column is declared as:

<telerik:GridDateTimeColumn DataField="Expires" DataFormatString="{0:g}" ReadOnly="false" PickerType="DateTimePicker"

HeaderText="Expires" UniqueName="Expires" SortExpression="Expires" AllowFiltering="false" ConvertEmptyStringToNull="true" >

</telerik:GridDateTimeColumn>

While debugging, these statements do get executed and the Columns value is updated to 2. When I test the result in the browser the TimeView still pops up with a 3 column layout - so the code appears to have had no effect.

Is the itemDataBound event the wrong event for such a change? I've tried to add similar code to the ItemCreated event but not been able to access the editor there at all.

DateTime Filter Problem

I'm trying to use the MonthYearPicker as my control for filtering datetime. However, when I try the code below, I get:


String was not recognized as a valid DateTime.
I've tried formatting several ways with no luck. I was trying to look at the event in the code behind, but I see no arguments at all that contains my filter values themselves. Just the  column name and expression.  Any help would be appreciated. Than you!





<

FilterTemplate>

<telerik:RadMonthYearPicker ID="RadMonthYearPicker1" runat="server" ClientEvents-OnPopupClosing="MeasurementDateChanged" />

<telerik:RadScriptBlock ID="RadScriptBlock3" runat="server">

<script type="text/javascript">

function MeasurementDateChanged(sender, args) {

var tableView = $find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

var year = args._picker.FocusedDate[0];

var month = args._picker.FocusedDate[1];

var fromDate = new Date(year, month-1, 1);

var toDate = new Date(year, month, 0);

tableView.filter("MeasurementDate", fromDate.toISOString() + " " + toDate.toISOString(), "Between");

}

</script>

</telerik:RadScriptBlock>

Hotkey shortcut underline is not congruent.

the Hotkey short text is not congruent, some of the button with the same hotkey text is displayed different, I what I mean, is that the underline is closer to the letter on some buttons and other have more space below the texts and the underline. The hotkeys are all using the same code.

I have attached a picture for clarity.
any solution or ideas.

RadTreeView in Master Page

Hi, I can not keep the state of the tree in the Master page.
This is my code

public List<string> BindNodes

{

get

{

List<string> dataNodes = new List<string>();

dataNodes.Add("item1");

dataNodes.Add("item2");

dataNodes.Add("item3");

return dataNodes;

}

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

BindTree();

}

private void BindTree()

{

List<string> data= BindNodes;

for (int i = 0; i < data.Count; i++)

LoadRecursive(data[i], null);

}

private void LoadRecursive(string item, RadTreeNode parentNode)

{

if (parentNode == null)

{

RadTreeNode childNode = new RadTreeNode();

childNode.Value = "5";

childNode.Text = item;

childNode.Category = "category1";

childNode.ExpandMode = TreeNodeExpandMode.ClientSide;

tree.Nodes.Add(childNode);

parentNode = childNode;

}

List<string> secondList= new List<string>();

secondList.Add("sec1");

secondList.Add("sec2");

for (int i = 0; i < secondList.Count; i++)

{

RadTreeNode childNode = new RadTreeNode();

childNode.Value = "5";

childNode.Text = secondList[i];

childNode.Category = "category2";

childNode.ExpandMode = TreeNodeExpandMode.ClientSide;

parentNode.Nodes.Add(childNode);

//LoadRecursive(subSite[i], childNode);

}

protected void tree_NodeClick(object sender, RadTreeNodeEventArgs e)

{

switch (tree.SelectedNode.Category.ToString())

{

case "category1":

Response.Redirect("~/Member/Cat1.aspx?id=" + tree.SelectedValue);

break;

case "category2":

Response.Redirect("~/Member/Cat2.aspx?id=" + tree.SelectedValue);

break;

}

I looked at other similar threads in the forum, but couldn't do it
