just trying the HtmlChart from Version 2012.2.724.35 using a List DataSource and the sample code from the HtmlChart List demo. While running the control in IE9, discovered this javascript error

The Java Debug returns an error

Expected ']' at line

[-] this._dataSource "[[{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45}]{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45},{\"MarketShare2010\":0.19,\"MarketShare2011\":0.45}]"

It appears to be malformed. Any suggestions are appreciated

Problems after Q3

I'm relatively new to Telerik, under a year, and everything has been going great so far, up until I installed Q3 yesterday - that's when the blank hit the fan!

My VS2010 did not crash like others reported, however, the minute I launched my website I had crash after crash dealing with my Master page - not 10 minutes before, under Q2, it worked perfectly!

I opened a ticket, sent the error info and other info to get to the bottom of it.

Then I decided to go back to Q2 so I uninstalled all Teleriks, got Q2 and installed it and thank heavens, when I launch my website, it does not crash and that's good.

But then I found this odd ball problem, if you look at the before and after attached jpgs you'll see when I call RadAlert() all of the RadTextboxes lose their style! After clicking OK on the RadAlert, you have to hover the mouse over each textbox to revert it back to the before jpg.

I need help with this problem (and this is while running Q2!). All of the other updates went really well too!

Thanks in advance!

Vertical align of button within wollbar

Hello,

[update: the title contains a typo: is not a wollbar, it's a toolbar]

I'm using the Toolbar with the metro touch skin.
I have a template tab with a textbox and a button inside of it.
The textbox is aligned correctly but the button appears lower than the other controls.
Could you please let me know how to position the button on top aligment?
I already tried wrapping the content within a div like the following with no results:
<div style="vertical-align:top; height:40px">

Thanks,

ToolBar

Reload grid in RadWindow1 when RadWindow2 closes

Hi!
I have a page that opens a radwindow with a radgrid.
When I click a row in the grid, I open another radwindow with the details.
When i save the details and close that second window, I want the grid to reload.

Both RadWindows are in a RadWindowManager on the main page, so any OnClientClose event ends up there.
Is there any way to access the first radwindow and refresh the grid from the parent page, or add a listener to it so it knows when the second window closes?

InvalidOperationException when loading dynamically RadComboBoxes with ITemplate

Hi,

I have an ASPX page (WebReportGenerator.aspx) which contains an ASCX custom control (Palette.ascx). That custom control is in fact just a panel where I load some RadComboboxes dynamically based upon the results of a stored procs.

WebReportGenerator.aspx :

<body>

<form id="formWebReportGenerator" runat="server" onmouseup="DisableDrag();" onmousemove="resizePanel();">

<CustomControl:Palette ID="PaletteControl" runat="server">

</CustomControl:Palette>

</form>

</body>

The page_load of the WebReportGenerator just create some RadComboBoxes and ask to the CustomControl Palette to display them in an PlaceHolder.

WebReportGenerator.aspx.cs :

protected void Page_Load(object sender, EventArgs e)

      {

          GetSomeComboBoxes();

          PaletteControl.WebReportGeneratorView = this;

          PaletteControl.SetDimensionsPanel(ContextSelector);//ContextSelector is a class which contain some ComboBoxes

      }

As I said previously my custom control Palette.ascx have a Place Holder which is in an UpdatePanel.

Palette.ascx :

<asp:UpdatePanel runat="server">

    <ContentTemplate>

        <asp:PlaceHolder ID="DimensionsHolder" runat="server"></asp:PlaceHolder>

    </ContentTemplate>

</asp:UpdatePanel>

Here is what my SetDimensionsPanel function looks like :

Palette.ascx.cs:

internal void SetDimensionsPanel(ContextSelector contextSelector)

{

    foreach (var comboBox in contextSelector.HierarchicalComboBoxes.Values)

    {

        DimensionsHolder.Controls.Add(comboBox);

    }

}

The RadComboBoxes are in fact in a Custom User Control (ComboBoxView.ascx). Please look at the code lower.

ComboBoxView.ascx

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="ComboBoxView.ascx.cs"

    Inherits="AS.Cpm.Web.Site.WebReportGenerator.Views.ComboBoxView" %>

        var dimensionString = "";

        for (var i = 0; i < checkedNodes.length; i++) {

                dimensionString += checkedNodes[i].get_text();

            }

        combo.set_text(dimensionString);

        var node = eventArgs.get_node();

        var combo = $find("<%= RadComboBox.ClientID %>");

        var checkedNodes = sender.get_checkedNodes();

        for (var i = 0; i < checkedNodes.length; i++) {

            }

_hierarchicalComboBoxAge.InitNonHierarchicalComboBox("", CreateSomeItems("Age"), false);

_hierarchicalComboBoxAge.ID = "Age" + "§" + "NotDefined";

comboBoxViews.Add(_hierarchicalComboBoxAge);

//Hierarchical

ComboBoxView _hierarchicalComboBoxTree = (ComboBoxView)new UserControl().LoadControl("~/Controls/ComboBoxView.ascx");

_hierarchicalComboBoxTree.InitHierarchicalComboBox("", CreateSomeNodes("Tree"), false);

_hierarchicalComboBoxTree.ID = "Tree" + "§" + "NotDefined";

comboBoxViews.Add(_hierarchicalComboBoxTree);

The problem :

When I first load the page everything is ok. I get my ComboBoxes in my ContextSelector object which is stored in the ViewState of the page and there is no Exception fired. On post back, I have to clear the placeholder and then add some different ComboBoxes. However on each postback I have an Exception :

The reason why I'm opening that thread here is because when I replace the ComboBoxes with simple Button, it works perfectly.

So does anyone know how to fix this or has a better solution to this?

Thanks.

the average fucntion is showing average of a page in radgrid instead of average of whole grid

Hi
the average fucntion is showing average of a page in radgrid instead of average of whole grid. In all other places that I have used the average function:

FooterAggregateFormatString

="{0:n0}" Aggregate="Avg" DataType="System.Double"

It work fine. But in one grid alone. the average is showing for each page. I am not getting what is gone wrong in this grid.
Thanks in advance.

Found the solution, it was something is to do with grouping being denabled in the grid.
