Adding line graph with months and a point for each day

I have data that I need to add a point for each day. I have my code working well enough to label my x axis as mar feb apr etc. Where I'm stuck is on how I add all of the data points.
I have the stored in a datatable with three fields, label (the month), position (an int of its position i.e. 0 is jan, 1 is feb etc), and value (the daily value)

Here's the code I have so far on trying to add the points but it doesn't seem to be working. I'm fairly new with these charts, so please bear with me.

'a holder for the current month

Dim currentMonth = ""

'a holder for the count

Dim count = -1

Dim rangeTable As New DataTable

rangeTable.Columns.Add("Label")

rangeTable.Columns.Add("Position")

rangeTable.Columns.Add("Value")

Using myconn As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("connection").ToString)

myconn.Open()

Dim cmd = New SqlCommand(sql, myconn)

Dim reader = cmd.ExecuteReader()

While reader.Read()

'if the currentMonth is new, then we add it to the data table for a range

If Not (currentMonth = (Format(reader("DateHour"), "MMMM"))) Then

currentMonth = Format(reader("DateHour"), "MMMM")

count = count + 1

End If

rangeTable.Rows.Add(currentMonth, count, reader("PointAverage"))

'Dim tempSeries As New ChartSeries

'tempSeries.SetValues(1, 2)

'chart.Series.Add(tempSeries)

End While

myconn.Close()

End Using 'using myconn

'add the range

chart.PlotArea.XAxis.AddRange(0, count, 1)

For Each i As DataRow In rangeTable.Rows

chart.PlotArea.XAxis(i("Position")).TextBlock.Text = i("Label")

Dim tempSeries As New ChartSeries

tempSeries.SetValues(i("Position"), i("Value"))

chart.Series.Add(tempSeries)

Next

A sample of what my data table would look like is something like this
Label Position Value
january 0 10
january 0 20
january 0 30
february 1 10
february 1 20
etc.

Essentially, I need to add all of the points in each month, but they are in succession by day. So I pull all of the days for jan, feb, and so on. Any ideas on how to go about this?

Moving from RadGrid to Kendo UI Grid

Hi

I currently use RadGrids for displaying data on mobile devices and am having trouble with the Client Side Select column. It will only allow a single select to be made even though multi row select is true - it works fine on a PC browser.

Will switching to the Kendo UI Grid be more compatible with mobile browsers and if so what is the transition from RadGrid to KendoGrid like, for example can I still bind to a list of items server side during page load?

Cheers
Cliff

Bullet List and IE

I'm having trouble with IE not handling and producing the same results with bulleted lists than other browsers.

I've pasted the same HTML in the online demo on Telerik and I still get the same issues across browsers.

The following is HTML created by my client, you can see a mix of P tabs and BR tags, but yet when highlighting two paragraphs, the browsers handle creating the bullets positions differently.

<p><strong>Lorem ipsum dolor sit amet, consectetur <br />

Lorem ipsum dolor sit amet, consectetur <br />

Lorem ipsum dolor sit amet, consectetur </strong></p>

<p

>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce ultricies dignissim diam, sed vestibulum metus semper sed. Nullam cursusLorem ipsum dolor sit amet, consectetur. </

p>

<p

>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce ultricies dignissim diam, sed vestibulum metus semper sed. Nullam . <

br />

<br />

<strong>Lorem ipsum</strong> <br />

RadInput breaks when inside jScrollPane using Chrome and Firefox

Hi there,

I am using jScrollPane (http://jscrollpane.kelvinluck.com/) for one of my project.

Whenever the scroller from jScrollPane is showing, none of the RadInput (RadTextBox, RadDateTimePicker) is selectable. It is like they are being disabled.

But if I am using the regular ASP.NET TextBox, this issue doesn't happen.

This only happens when i am using Chrome and FireFox. On IE 9, it works fine.

Below is the code i use to demonstrate the problem. The first DIV will show the scroller, the second DIV won't show the scroller. In the first DIV, I can't type anything to the RadTextBox, but on the normal TextBox, it is working.

On the second DIV, where the scroller is not showing, both textbox are working.

Thanks.

Accessing Controls in Template Columns on DataBound Grid via Client-Side Scripting

I have a data bound grid that also contains two template columns. One column contains a checkbox, the other contains a textbox. Only if the checkbox is checked should the textbox be enabled. I have added code that does this on the server side, but I'd rather execute this on the client side to reduce processing on the server.

Here's the grid definition:

<telerik:RadGrid ID="grdContentManagement" runat="server" SkinID="StaticColumnsNoPagingBuiltInSorting"

OnItemCommand="ContentManagementGridItemCommand" OnNeedDataSource="grdContentManagement_NeedDataSource"

OnItemDataBound="grdContentManagement_OnItemDataBound" CellSpacing="0" GridLines="None"

AllowSorting="True" AllowPaging="True" PageSize="15" Height="478" ShowFooter="false">

<MasterTableView DataKeyNames="Id" ClientDataKeyNames="Id" AllowSorting="true">

<Columns>

<telerik:GridTemplateColumn UniqueName="Selected" HeaderText="Display" HeaderStyle-HorizontalAlign="Center"

HeaderStyle-Width="50px" ItemStyle-HorizontalAlign="Center">

<ItemTemplate>

<asp:CheckBox ID="chkSelected" runat="server" onclick="CheckBoxClicked(this)" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn HeaderText="Property" UniqueName="PropertyName" DataField="PropertyName"

SortExpression="PropertyName" HeaderStyle-Width="200px">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn UniqueName="DisplayName" HeaderText="Label" HeaderStyle-Width="200px"

SortExpression="DisplayName">

<ItemTemplate>

<telerik:RadTextBox ID="txtDisplayName" runat="server" MaxLength="255" Width="100%" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn HeaderText="Data Type" DataField="DataType" SortExpression="DataType"

HeaderStyle-Width="100px">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn HeaderText="Object Type" DataField="ObjectType" SortExpression="ObjectType" />

<telerik:GridBoundColumn DataField="Id" SortExpression="Id" Visible="false" />

</Columns>

<EditFormSettings>

<EditColumn FilterControlAltText="Filter EditCommandColumn column">

</EditColumn>

</EditFormSettings>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="True" />

<Scrolling UseStaticHeaders="False" />

<Resizing EnableRealTimeResize="true" />

</ClientSettings>

<FilterMenu EnableImageSprites="False">

<WebServiceSettings>

<ODataSettings InitialContainerName="">

</ODataSettings>

</WebServiceSettings>

</FilterMenu>

</telerik:RadGrid>

I create the checkboxes as follows:

protected void grdContentManagement_OnItemDataBound(object sender, GridItemEventArgs e)

{

GridDataItem item = e.Item as GridDataItem;

if (item != null)

{

TelerikGridHelper.SetGridToolTips(item as GridDataItem);

TelerikGridHelper.SetGridHtmlEncode(item as GridDataItem);

CheckBox chkBox = (CheckBox)item["Selected"].Controls[1];

chkBox.Checked = ((ContentManagementFieldForDisplay)(item.DataItem)).Selected;

chkBox.Attributes.Add("rowIndex", item.ItemIndex.ToString());

RadTextBox txtBox = (RadTextBox)item["DisplayName"].Controls[1];

txtBox.Text = ((ContentManagementFieldForDisplay)(item.DataItem)).DisplayName;

}

The issue I'm experiencing is that I can't figure out how to access the textbox based on the checkbox row index on the client side. If I place an alert in the following code, it will fire whenever the box is checked/unchecked, so I know it's reaching that point in code, but trying to access the "rowIndex" attribute I defined for the checkbox on the server side doesn't work.

function CheckBoxClicked(checkBox) {

if (checkBox.checked) {

//enable the textbox

}

else {

//disable the textbox

}

Any ideas?

Drag/Drop overlay won't go away using Metro theme

Hi there,

When I use the Metro theme, any page that has a RadAsyncUpload control, when the page loads the overlay is visible and will not go away.

This is using the latest Chrome and FireFox.

This is the declaration:

<telerik:RadAsyncUpload ID="RadUploadAlertDocuments" runat="server" AutoAddFileInputs="true"

MaxFileSize="2147483647" MultipleFileSelection="Automatic"

InputSize="70">

</telerik:RadAsyncUpload>

Attached is what shows as soon as the page loads.

Can the overlay be disabled completely? I couldn't find a property for it.

Thanks!!!!!

reset paging after node loses focus

I'm relatively new to using the RadGrid, but I'm sure there's a way to do what I'm trying to do--I just don't know where to start.
I've got a 3-level hierarchical grid. In any of the levels, if there is paging taking place I need to reset the page anytime that node loses focus. In other words, if a user starts working in one node but switches to another (whether already expanded or not), I need to reset the page to page 1 for the node that lost focus.
I didn't see any obvious examples of this, or at least nothing that deals with the complexity of managing 3 levels. Any advice would be greatly appreciated.

Thanks,

Glen MacAfee
