One one page I use the radchart and it's all working fine.
at the top of that working page I have ...

<%

@ Register Assembly="RadGrid.Net2" Namespace="Telerik.WebControls" TagPrefix="radG" %>

Now I create a new page and I want a radchart on it

I do this ...

<%

@ Register Assembly="RadChart.Net2" Namespace="Telerik.WebControls" TagPrefix="radC" %>

and i put in this code ....

<

radC:RadChart ID="RadChart1" runat="server" Width="480px" Height="290px">

</radC:RadChart>

and it says "Chart has no or empty series?"

but if I put in this code ....

<

radC:RadChart ID="RadChart1" runat="server" Width="480px" Height="290px">

<radC:ChartSeries Name="1">

<Items>

<radC:ChartSeriesItem YValue="1" Name="1"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="2" Name="2"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="3" Name="3"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="4" Name="4"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="5" Name="5"></radC:ChartSeriesItem>

</Items>

</radC:ChartSeries>

<radC:ChartSeries Name="2" YAxisType=Secondary>

<Items>

<radC:ChartSeriesItem YValue="10" Name="1"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="20" Name="2"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="30" Name="3"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="40" Name="4"></radC:ChartSeriesItem>

<radC:ChartSeriesItem YValue="50" Name="5"></radC:ChartSeriesItem>

</Items>

</radC:ChartSeries>

Updating RadDock Title on PostBack

Hi,

I have a RadDock that has a user control inside it. The control is embedded in a RadAjaxPanel. The rough structure is something like this

<telerik:RadDock id="xxxxx"..........................>
<ContentTemplate>
     <telerik:RadAjaxPanel id="xxxx"......................>
         <Usercontrol:Mycontrol   Id="xxx" runat="server" onButtonClick="Button_Click"............ />
     </telerik:RadAjaxPanel>
</contentTemplate>
</telerik:RadDock>

Whenver the Button_Click event is fired, I want the RadDock title to be updated.
Is there a way we could achieve this ?

http://demos.telerik.com/aspnet-ajax/editor/examples/builtincontentfilters/defaultcs.aspx
But does not stop from converting & to &amp (also £ to &pound)

pl see the attached files contentfilter1.png and contentfilter2.png

Also tried adding code as well as specified in http://www.telerik.com/support/kb/aspnet-ajax/editor/converting-unicode-symbols-to-numeric-html-entities-using-a-content-filter.aspx

ItemDataBound event in Dynamic Treeview

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!
