I'm displaying a relatively simple chart plotting time of the xaxis and counts on the yaxis. the chart displays fine, but I simply cannot get the xaxis labels to display as time values! I've tried all the suggestions I could find in the forums with no luck.
Here is my aspx file:

<%@ Page Title="Tickets Received by Time of Day" Language="VB" AutoEventWireup="false" CodeFile="TixByTime.aspx.vb" Inherits="Statistics_Misc_TixByTime" MasterPageFile="~/MasterPage.master" %>

<%@ MasterType VirtualPath="~/MasterPage.master" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Charting" TagPrefix="telerik" %>

<asp:Content ID="cpHeadContent" ContentPlaceHolderID="mpHeadContent" runat="server">

</asp:Content>

<asp:Content ID="cpSideMenuContent" ContentPlaceHolderID="mpSideMenuContent" runat="server">

</asp:Content>

<asp:Content ID="cpMainContent" ContentPlaceHolderID="mpMainContent" runat="server">

<telerik:RadChart ID="rcChart2" runat="server" Height="500px" Width="900px" Skin="WebBlue">

</telerik:RadChart>

</asp:Content>

And here is my codebehind:

Imports Workforce

Imports System.Data

Imports Telerik.Charting

Imports System.Data.SqlClient

Partial Class Statistics_Misc_TixByTIme

Inherits System.Web.UI.Page

Protected Sub Page_Load(sender As Object, e As System.EventArgs) Handles Me.Load

SetupChart()

LoadData()

End Sub

Private Sub SetupChart()

Dim dStart As Double = DateTime.Today.ToOADate()

Dim dEnd As Double = DateTime.Today.AddDays(1).ToOADate()

Dim dHourStep As Double = (1 / 24)

With rcChart2

.ChartTitle.TextBlock.Text = "Tickets Received by Time of Day"

.SeriesOrientation = ChartSeriesOrientation.Vertical

With .PlotArea.XAxis

.AutoScale = False

.IsZeroBased = False

.LayoutMode = Styles.ChartAxisLayoutMode.Inside

.AddRange(dStart, dEnd, dHourStep)

.Appearance.MajorGridLines.Visible = False

.Appearance.ValueFormat = Styles.ChartValueFormat.ShortTime

.Appearance.CustomFormat = "hh:mm tt"

.Appearance.LabelAppearance.RotationAngle = 90

.Appearance.LabelAppearance.Position.AlignedPosition = Styles.AlignedPositions.Top

End With

With .PlotArea.YAxis

.Step = 1

End With

Dim oSeries As New ChartSeries()

With oSeries

.Name = "TicketCounts2"

.Type = ChartSeriesType.Area

.Appearance.ShowLabels = False

End With

.Series.Add(oSeries)

End With

End Sub

Private Sub LoadData()

Dim oSeries As ChartSeries = rcChart2.Series(0)

Dim oConn As SqlConnection = Nothing

Dim oReader As SqlDataReader = Nothing

Dim oCmd As SqlCommand = New SqlCommand()

Dim sSQL As String

Try

Dim sConn As String = Profile.Company.ConnectionString

oConn = New SqlConnection(sConn)

oConn.Open()

sSQL = <sql>

SELECT Substring(Convert(nchar(8),recvdatetime,8), 1, 5) AS daTime

,Count(*) AS daCount

FROM cwtg..tix4tbl

group by substring(convert(nchar(8),recvdatetime,8), 1, 5)

order by daTime

</sql>.Value

oCmd.CommandText = sSQL

oCmd.Connection = oConn

oReader = oCmd.ExecuteReader()

Do While oReader.Read

Dim dTime As Double = DateTime.Parse(oReader.GetString(oReader.GetOrdinal("daTime"))).ToOADate()

Dim dCount As Double = oReader.GetInt32(oReader.GetOrdinal("daCount"))

Dim oItem As New ChartSeriesItem()

oItem.XValue = dTime

oItem.YValue = dCount

oSeries.Items.Add(oItem)

Loop

Finally

If oReader IsNot Nothing Then oReader.Close()

oConn.Close()

oConn.Dispose()

End Try

End Sub

End Class

The values are all correct, but the xaxis labels display as 41047, 41047.0416, ... 41047.9999 (the last digits of the labels are truncated)

RadSplitter and MOSSRadEditor on the same page causes splitter bug

Hello,

I have these two controls on the same page, the splitter containing a RadTreeview, a Formview and a gridview (left, right and bottom panes).
When I add a MOSSRadEditor, the vertical splitter shows a horizontal resizing icon, and allows resizing "horizontally" (though the orientation is "Vertical")...

Is there a workaround ?

RadAjaxPanel not updating __ViewState

I'm having a problem with my RadAjaxPanel and my viewstate.

We are keeping our last ten viewstates in session. The problem is on a certain page.. the user hits the page and selects a CATEGORY from a drop down. Another drop down is populated with CategoryTYPES depending on the CATEGORY that was selected.

To keep the page from posting back, I have a RadAjax panel around the controls on the page.

After selecting a CATEGORY/TYPE, the user can add that combination to a listbox and select another CATEGORY/TYPE. These selections are then used in a search that populates a RadGrid.

Our legacy system allowed the users to then use the browser back / forward buttons to move backward and forward, which loaded each viewstate version from memory. So each step was saved.

With my RadAjax panel on the page though, the hidden __VIEWSTATE value is not being updated on the page. I can see my SavePageStateToPersistenceMedium Sub is firing and that my subsequent viewstates are being saved to memory, but since the hidden field isn't being updated on the page, I'm continually loading the wrong version of the page (the original version from when I first hit the page) after doing an actual postback.

I think my main problem is the hidden field __VIEWSTATE is not getting updated. The hidden field has no runat="server" on it since it's being put there dynamically, and although I've managed to find the control and read the value from it, I can't find a way to update it during the ajax postback.

I've tried adding EnableViewState="true" to my ajax panel, but I'm still not updating the hidden field on the page when then ajax postback occurs.

I know I can't be the only one who's run into this and I'm hoping someone has a solution or even a work around that will allow me to keep track of where I'm at and what viewstate version I'm supposed to be loading when the user tries to browse backwards or forwards.

And yes, I know.. but they insist on being able to use the BACK and FORWARD browser buttons, so I have to live with it. :)

I appreciate any suggestions or tips on how I can get around this problem...

Bug in RadDatePicker options..

Hi,

If i create a control like this:

RadDatePicker date = new RadDatePicker();
            date.EnableTyping = false;
            date.ShowPopupOnFocus = true;

Disabling typing also disables Popup.. ..but i only want the popup, that's why i disable typing! :D

So now i have a control that allows no input at all!

Disabling typing should actually force popup = true

Also, you should probably not show a caret in the input box when typing is disabled. Very misleading.

break;
}

private void GridReport_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{
//do something

GridReport.DataSource = dt;}

void GridReport_PageIndexChanged(object source, GridPageChangedEventArgs e)

{

// DO SOMETHING, HERE THE BREAKPOINT NEVER HITS!
}

Thanks for your help!

Access GridTemplateColumn?

How do I access a GridTemplateColumn in the Grid row that was clicked?

With the getDataKeyValue() method I can get the value of GridBoundColumns after defining the columns using the ClientDataKeyNames property of the MasterTableView.

But how can I get the value of GridTemplateColumns?
