Hi,
Based on certain criteria Im binding items in RadMenu, in which am supposed to populate the RadTreeView inside one of the RadMenuItem (named "Tools") dynamically. Ive done this using ItemDataBound of RadMenu. (below is the Code) :

protected void TopMenu_ItemDataBound(object sender, RadMenuEventArgs e)

{

if (!string.IsNullOrEmpty(e.Item.NavigateUrl))

e.Item.Attributes["onclick"] = "return Redirect(this.href);";

if (e.Item.Text.ToLower() == "Tools".ToLower())

{

RadMenuItem radTools = new RadMenuItem();

RadTreeView radToolTreeView = new RadTreeView();

radToolTreeView.DataTextField = "Text";

radToolTreeView.DataFieldID = "MenuID";

radToolTreeView.DataFieldParentID = "ParentID";

radToolTreeView.DataNavigateUrlField = "Url";

radToolTreeView.LoadingMessage = "Loading...";

radToolTreeView.Skin = "Web20";

radToolTreeView.CssClass = "MenuTreeView";

radToolTreeView.DataSource = BindToolMenu1();

radToolTreeView.BackColor = System.Drawing.Color.Aqua;

radToolTreeView.DataBind();

radToolTreeView.ExpandAllNodes();

radTools.Controls.Add(radToolTreeView);

e.Item.Items.Add(radTools);

}

from the above code, I am able to set the attributes for RadMenuItem

e.Item.Attributes["onclick"] = "return Redirect(this.href);";

I need to set the same attribute on clicking on TreeViewNode. Please tell me how to do this?

Thanks in advance

History Points and RadGrid

I'm hoping someone can help me by either pointing me to a straight forward example or pointing out the error(s) in my code. I'm attempting to provide history points when a user is interacting with an ajax grid. I've started just with paging but eventually want to get this working with sorting as well.

I have a master page which defines a RadScriptManager:

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnablePartialRendering="true" EnableHistory="true" EnableSecureHistoryState="false"></telerik:RadScriptManager>

On a content page I have a ScriptManagerProxy to invoke the OnNavigate event (when a browser back/forward button is clicked):

<asp:ScriptManagerProxy ID="ProxyScriptManager" runat="server" OnNavigate="ScriptManager_OnNavigate" />

The ScriptManager_OnNavigate handler is defined as such:

protected void ScriptManager_OnNavigate(object sender, HistoryEventArgs e)

{

if (e.State.Count <= 0)

{

// setup default state

RadGrid1.MasterTableView.CurrentPageIndex = 0;

RadGrid1.Rebind();

return;

}

string key = e.State.AllKeys[0];

string state = string.Empty;

if (string.Equals(key, GridPageHistoryKey))

{

state = e.State[key];

int pageIndex;

if (int.TryParse(state, out pageIndex))

{

RadGrid1.MasterTableView.CurrentPageIndex = pageIndex;

RadGrid1.Rebind();

}

On the grid's OnPageIndexChanged event handler, I set a private variable to true which is then checked in the grids OnPrerender event:

protected void RadGrid1_PageIndexChanged(object sender, GridPageChangedEventArgs e)

{

_saveState = true;

}

protected void RadGrid1_PreRender(object sender, EventArgs e) {

if (_saveState)

{

if (RadScriptManager.GetCurrent(this.Page).IsInAsyncPostBack && !RadScriptManager.GetCurrent(this.Page).IsNavigating)

{

var state = RadGrid1.MasterTableView.CurrentPageIndex.ToString();

RadScriptManager.GetCurrent(this.Page).AddHistoryPoint(GridPageHistoryKey, state);

}

It appears that the add history point is getting created and the OnNavigate code is executing but the grid doesn't update when clicking the back button. Am I missing a crucial step? Is there an example that doesn't just point me to: http://www.telerik.com/help/aspnet-ajax/ajax-back-forward-btns.html

Thanks for any help!

Rad Textbox IE 7 Compatibility View Issue

Filtering a DateTimeColumn that displays time

I am trying to filter a GridDateTimeColumn that has the the DataFormatString = "{0:MM/dd/yyyy hh:mm tt}" and PickerType ="DatePicker"

The DataField = "ReferralDate" which is a Nullable<DateTime> property on my business object.

I would like to filter on date and simply ignore the time. For example if the data in the grid contains:

3/11/2012 3:23 PM
1/4/2011 12:00 AM
3/11/2012 12:00 PM

Applying the filter "3/11/12" "EqualTo" will produce the following:

3/11/2012 3:23 PM
3/11/2012 12:00 PM

I've been looking through the forums for a solution and found lots of posts related to GridDateTimeColumns and filtering which I'm finding to be either incomplete as far as a solution goes or not really applying to my specific need. Any help/direction would be appreciated!

$telerik VS Sys.Componet.find() or $find()

I've noticed after updating several sites to the newest hot fix version, and adjusting the Script Manager on the page to include the telerik's Jquery core Module. that $telerik is alot cleaner, easier to use and just generally better than the methods used in the tutorials and help files (eg. $find('Controlname');)

is there a reason we shouldn't be using the $telerik, are there situations where one shouldn't concisder this (like where Jquery isn't loaded or used) i'm at a loss for other situations where it's use would cuase issues.

I understand it takes time to update documentation. that's not really the point.

Tooltips not generating

I'm creating a line chart with multiple series created dynamically.

Here is the code.

For Each mdItem As ModalityTrendWrapper In ModalityTrend

Dim newSeries As New Telerik.Charting.ChartSeries()

newSeries.Name = mdItem.Modality

newSeries.Type = ChartSeriesType.Line

For Each dateCount As ModalityTrendItem In mdItem.DateCounts

Dim chrItem As New ChartSeriesItem()

chrItem.YValue = dateCount.Count

chrItem.Name = dateCount.Modality

chrItem.Label.TextBlock.Text = dateCount.Count

chrItem.ActiveRegion.Tooltip =dateCount.Modality

newSeries.Items.Add(chrItem)

Next

RadChart1.Series.Add(newSeries)

Next

Dim MaxValue As Integer = Enumerable.Range(0, CInt(ModalityTrend.Count)).Select(Function(ex) ModalityTrend(ex).DateCounts.Max(Function(dc) dc.Count)).Max()

RadChart1.ClientSettings.XScale = DateList.Count / 7

RadChart1.PlotArea.XAxis.AddRange(1, DateList.Count, 1)

RadChart1.PlotArea.YAxis.MaxValue = MaxValue + 2

For i As Integer = 0 To DateList.Count - 1

RadChart1.PlotArea.XAxis(i).TextBlock.Text = DateList(i)

RadChart1.PlotArea.XAxis(i).Appearance.Border.Visible = True

Next

For some reason the tooltips just aren't showing up. Is there anything that I'm missing?
