Stacked Columns - Y-axis grows logarithmically with each new series

I'm having an issue I can't find any similar posts to so here goes.

I am generating a pivot table using Linq where I won't know the column names until run-time. So I am creating the data series in codebdhind and then binding the Radhtmlchart to the data table. Things work somewhat well but for one problem. Each new series I add changes the Y-Axis scale by a factor of 10. I have added images below to show how it grows (data points are set to 1 or 2 in each case for simplicity). Note that the Y-axis grows from roughly 1 to 10 to 100 and the column height of each successive series is correspondingly bigger.

Here is the aspx for the Chart:

<telerik:RadHtmlChart ID="RadHtmlChart1" runat="server">

<PlotArea>

<XAxis DataLabelsField="DayHour">

<LabelsAppearance Step="4">

</LabelsAppearance>

</XAxis>

<YAxis Type="Numeric">

<LabelsAppearance Step="1">

</LabelsAppearance>

</YAxis>

</PlotArea>

<Appearance>

<FillStyle BackgroundColor="Transparent"></FillStyle>

</Appearance>

<ChartTitle Text="Hourly Clicks">

<Appearance Align="Center" BackgroundColor="Transparent" Position="Top">

<TextStyle Bold="true" FontSize="24px" />

</Appearance>

</ChartTitle>

<Legend>

<Appearance BackgroundColor="Transparent" Position="Bottom"></Appearance>

</Legend>

</telerik:RadHtmlChart>

And here is the codebehind where I generate the ColumnSeries dynamically and bind. There is some code to test different configurations of the 'stacked' attribute based on some older articles I saw but it was not helpful. T is the Data Table and looks exactly as it should.

int i = T.Columns.Count;

bool bstacked = true;

foreach (DataColumn col in T.Columns)

{

if (col.ColumnName == "DayHour") continue;

ColumnSeries newSeries = new ColumnSeries();

newSeries.Name = col.ColumnName;

newSeries.GroupName = "colGroup";

newSeries.DataFieldY = col.ColumnName;

i--;

if (i == 1) bstacked = false;

newSeries.Stacked = bstacked;

newSeries.LabelsAppearance.Position = Telerik.Web.UI.HtmlChart.BarColumnLabelsPosition.OutsideEnd;

RadHtmlChart1.PlotArea.Series.Add(newSeries);

}

RadHtmlChart1.DataSource = T;

RadHtmlChart1.DataBind();

I would appreciate any help with this.

Thanks.

RadGrid Hierarchy - Custom Command Item

Hi,

Initially, we had a RadGrid whose DataSource is assigned via NeedDataSource (via List Of). All worked perfectly. We now need to add a hierarchical system to have a Parent / Child relationship at the level of our bookings. Visually, the display is what we want.

However, I can not Bind the CommandItemTemplate actions for the DetailTable (RadToolBarGridChildEdit). How can I get information from my parent item for the FireCommand?

Thank you and have a good day

Javascript

01.function onPanelBarItemClicked(sender, args) {

02. var button = args.get_item();

03.

04. switch (args.get_item().get_commandName()) {

05. case "AddResource":

06.

//Ajouter une nouvelle ligne.  Le paramètre "InitInsert" est OBLIGATOIRE et DOIT être écrit EXACTEMENT comme il est inscrit

07. var argument = args.get_item().get_commandArgument();

08. document.getElementById('<%=gridMid.ClientID%>').value = argument;

09.

10. $find('<%= RgPanelSummary.ClientID%>').get_masterTableView().fireCommand("InitInsert", argument);

11. break;

12.

13. case "AddChildResource":

14.

//Ajouter une nouvelle ligne.  Le paramètre "InitInsert" est OBLIGATOIRE et DOIT être écrit EXACTEMENT comme il est inscrit

15. var argument = args.get_item().get_commandArgument();

16. document.getElementById('<%=gridMid.ClientID%>').value = argument;

RadGrid Javascript Problem

Hi everybody,

I have a ASP page with a UserControl. In this userControl I have a Radgrid implement with hierarchy.

Invalid postback or callback argument.

Hey people,
now ive tried to use the radajax panel at a certain time am getting the error as
"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation."

i find no actions take place if i click enableevent validation="false"

a)may i knw what is the cause of this error?
b)In Most of the Telerik Demo i find that they have been using sql datasource to bind data to the controls rather than code behind,wuld that be the reason for it?

Guys this is getting so serious and close pls just give me hint and ill be so greatfull to you all.
Awaiting for your Swift Reply
Thanks
Regards

[Solved] Help with Hierarchy in RadGrid

I have an ASP.NET Web Forms project i am working with and need some help with my grid.

I have a pretty basic grid on my page. i am able to populate it mostly.

i use codebehind to bind a list to it from c#.

I need to figure out how to perform this,

I have the proper data in my list to be bound to the grid. i want to have my rows show some important data to my customer, but when he expands the row the data in the expansion is more data from the same list, for that row.

so when a user is browsing the grid, they can click on any row and it does its thing, but if they click the expander icon they get a bit more data about the row.

I hope i explained this well, im about to break out mspaint and draw it up...

Could not load file or assembly 'Telerik.Windows.Documents.Spreadsheet, Version=2015.1.225.45'

When trying to use the export to excel functionality on my asp.net website the following error is displayed:

Could not load file or assembly 'Telerik.Windows.Documents.Spreadsheet, Version=2015.1.225.45, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Not sure why it is looking for version 2015.1.225.45 when the assembly references version 2016.2.421.40 and it is also set to Copy Local = True.

Have tried rebuild but still nothing. I have no idea where the old version is being referenced as I have searched the whole solution without success.

What is the solution here?
