Setting DataXColumn for every Databound Series

Hi,

I'm trying to put together a line chart showing transactions per day over a period of time, separated out by store. I noticed that the dates on the X-axis are not correct when compared to the actual data. The dates on the bottom of the page don't scale, (instead it just uses each date point, so a hash mark can be one day, then jump to a week) and rather than place the datapoint at the right date, it just places it on the next one over.

When I set the DataXColumn setting for some hardcoded series, it worked fine. So, is there a way to set the DataXColumn for each series and have the chart display the correct dates? My code is below.

<telerik:RadChart runat="server" ID = "chartTransactions" AutoLayout="true" DataSourceID="datTransactions" DefaultType="Line" DataGroupColumn = "Store" Width="800" >

<ChartTitle><TextBlock Text = "Transactions - Store"></TextBlock></ChartTitle>

<PlotArea>

<XAxis DataLabelsColumn = "AppRejDate" >

<Appearance ValueFormat="ShortDate">

<LabelAppearance RotationAngle="270">

</LabelAppearance>

</Appearance>

</XAxis>

</PlotArea>

</telerik:RadChart>

<asp:SqlDataSource ID = "datTransactions" runat="server"

ConnectionString="<%$ ConnectionStrings:DBString %>" SelectCommand = "Select tblStore_Ref.Description, CAST(DATEADD(Day, DATEDIFF(Day, 0, AppRejDateTime), 0) AS Float) + 2 AS AppRejDate, Count(*) as Transactions From tblTransactionHistory INNER JOIN tblTransactionItems ON tblTransactionHistory.TransactionID = tblTransactionItems.TransactionID INNER JOIN tblStore_Ref ON tblTransactionItems.Store = tblStore_Ref.Store Where Status = 'A' AND AppRejDateTime Between @dateBegin AND @dateEnd Group By DATEADD(Day, DATEDIFF(Day, 0, AppRejDateTime), 0), tblStore_Ref.Description Order By AppRejDate, tblStore_Ref.Description">

<SelectParameters>

<asp:ControlParameter ControlID = "dateBegin" Name = "dateBegin" PropertyName="SelectedDate" />

<asp:ControlParameter ControlID = "dateEnd" Name = "dateEnd" PropertyName="SelectedDate" />

</SelectParameters>

</asp:SqlDataSource>

Some sample data:

40513   S-2   1
40518   S-2   2
40519   S-2   1
40549   S-2   4
40553   S-2   3

Thanks.

Retrieve Data from underlying Datarow

Is it possible to retrieve the underlying datarow when in any of the RadGrid Events, e.g. ItemDatabound? If this can be done can someone post an example.

From reading various posts it would seem that one would need to access the grid itself to get any data, though it seems rather an overhead to add a hidden column to the grid to have the data bound to it and then retrieve values from the grid. In my case I simply want to retrieve values from the datasource and build a tooltip for each row and I could do without the clutter of numerous hidden grid columns.

Thanks for any help.

Regards
Alan

GirdDateTime Column Max Date

I have been trying to get this to work forever now.. is there something that I am just not seeing.

I am trying to set the max date from the code behind and it's just not cooperating... yet everything else is.

Here's the code behind in the item_created method:

if (e.Item is GridEditFormItem && e.Item.IsInEditMode)

{

GridEditFormItem dataItem = e.Item as GridEditFormItem;

TableCell cell = dataItem["InspectionDate"];

RadDatePicker rdp = cell.Controls[0] as RadDatePicker;

rdp.Calendar.UseColumnHeadersAsSelectors = false;

rdp.Calendar.UseRowHeadersAsSelectors = false;

rdp.MaxDate = DateTime.Now;

}

any ideas would be great... basically it can figure out that the date is too large if you pick past the date, but when the calendar pops up, the dates past today are not grayed out... If I set the max date manually in the markup, it works fine.

please let me know if you need any more info.

Thanks,

Dustin

Using RadAsyncUpload to add files to a Sharepoint document library?

Hi

I'm working on a Sharepoint 2010 installation, and have had a bit of trouble using the ASyncUpload in a custom Visual WebPart.

I can add files to the RadUploadTemp folder fine, and in fact any folder on the 80 hive, but as far as I can tell there is no way to upload into the 14 hive. Is this correct?

In the past, I have used the standard ASP FileUploader, with an IO Stream to upload directly to the url of my Sharepoint Library, but this does not seem to work with the RAD Async Upload, I just get this error:

'http://local-sharepoint/TestLibrary' is not a valid virtual path.

If I browse to that URL normally it works fine, and works fine with a standard uplader.

Any ideas what's going on here?

Thanks for any help

RadGrid Performance Issue

When clicking on a link in my RadGrid I am getting very slow performance. I've done some performance profiling in VS 2010 and with Fiddler and I've found the following.

First, there is a large amount of data being sent to the client (about 250kb) for an AJAX enable grid that can be paged, filtered and sorted. Bandwidth however isn't the problem because this is all running locally in my debug environment.

Since bandwidth wasn't the issue I decided to profile the code. When running VS Profiler and looking at the slow operations it tells me that the following functions are mostly responsible for the slow results:

gridItem.onBubbleEvent
system.text.regularexpressions.matchenumerator.movenext
system.text.regularexpressions.regex.match

Where onBubbleEvent is calling the functions beneath it and those function are responsible for 70% of the time it takes to render the page. Can anybody suggest ideas for improving the performance? If I had to guess I'd say that given the large amount of data that RadGrid is just having a tough time slogging through it all and rendering html.

How to create custom filter menu for one column

Greetings,

I created a custom filter menu that I want to use for one of my radgrid columns. It works fine, but the problem is the menu appears for all columns. I only want this menu to appear for the column "Constituents." Note that I can't use "VaryByDataType" because my columns are all strings. Is it possible to create a custom filter menu for just one column?

Automatically spellcheck a RadEditor?

I stumbled upon a previous question that dealt with forcing spellcheck in a RadEditor here: http://www.telerik.com/community/forums/aspnet/editor/force-spell-check.aspx, however the link provided by the Telerik team (http://www.telerik.com/Default.aspx?PageId=2202&b311D=FJIfc) has since expired.

Is there an updated solution (preferrably for ASP.NET AJAX controls) that will allow me to force a RadEditor to be spellchecked prior to allowing a web form submit?
