Hi,

I am creating a StackedBar chart from the code behind, where each item on the Y axis is the name of a Customer, and the X values are the amount of invoices completed/outstanding today. Please see the attached screenshot for an example.

It's working well, except the labels for each item on the Y axis is a meaningless number (1-5). How can I get the label to be 'Name' property of each item?

Thanks - the code is below

IEnumerable<Invoice> invs = Invoice.GetTestInvoices(100);

var s = from i in invs

group i by i.Name;

ChartSeries chtOutstanding = new ChartSeries("Outstanding", ChartSeriesType.StackedBar);

ChartSeries chtCompleted = new ChartSeries("Completed", ChartSeriesType.StackedBar);

chtOutstanding.Appearance.LabelAppearance.LabelLocation = Telerik.Charting.Styles.StyleSeriesItemLabel.ItemLabelLocation.Inside;

chtCompleted.Appearance.LabelAppearance.LabelLocation = Telerik.Charting.Styles.StyleSeriesItemLabel.ItemLabelLocation.Inside;

foreach (var item in s.OrderBy(a => a.Key))

{

chtCompleted.AddItem(item.Where(a => a.Status == 1).Count());

chtOutstanding.AddItem(item.Where(a => a.Status != 1).Count());

}

RadChart1.Series.Add(chtOutstanding);

RadChart1.Series.Add(chtCompleted);

Using Load On Demand with BinaryImage

We have images stored in a database as blobs which we want to load on demand into a slideshow. Is it possible to use the BinaryImage control convert and display the images into the radrotator control from a memory stream?
If this isn't the correct approach, how would we go about creating this functionality?

Your help is very much appreciated!

Thanks,

Ben

Multiple RadAsyncupload and RadProgressArea

Hi,
I have multiple radAsyncUpload controls in one page with radprogressarea control for each of them.I have also one radprogressmanager.
When a radAsyncUploadControl is uploading a file to the temporary folder then all the radprogressarea controls are displayed.
How I can limit that so when a file is uploaded only the relevant radprogressarea is displayed?

Thank you

GridAttachmentColumn does not insert

i have a radgrid with a gridattachmentcolumn column. the grid is bound to an entitydatasource having the 3 columns stipulated in the documentation - FileName, DataText, and Attachment, the last being a varbinary(max) column.

<telerik:GridAttachmentColumn AttachmentDataField="Attachment"

AttachmentKeyFields="ItemID,ForeignKeyID,AttachmentID"

DataSourceID="ItemAttachmentEntityDataSource" DataTextField="DataText"

FileName="attachment" FileNameTextField="FileName"

FilterControlAltText="Filter column column" HeaderText="Attachment"

UniqueName="Attachment">

</telerik:GridAttachmentColumn>

when i click add new record, fill in the three columns, the text columns are inserted but not the attachment. i thought that the insert would be handled by the grid, yet all of the examples for gridattachmentcolumn i have seen include a prodigious amount of code to handle the insert. do i need to manually insert the data myself? if so, what is the point of the column type? which event would be the best one to write the code? i am handling the insertcommand so would hope there are no objections to doing it there.

if indeed i am required to manually insert the data, please update your documentation to stress this point. if radgrid can declaratively handle my scenario, are there any reasons why my insert is failing?

if (!Page.IsPostBack)

{

rCal.RegisterWithScriptManager = false;

rCal.RangeMinDate = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day);

if (SelectedDateForSearch.HasValue)

{

rCal.SelectedDate = SelectedDateForSearch.Value;

rCal.FocusedDate = SelectedDateForSearch.Value;

}

Show file size next to file name

Hello,

Could somebody help me ? What I have been trying to do is to show our users not just file name, but also file size information (ContentLength), when file is selected and uploaded...

It seems that from server side method there are just readonly properties about uploaded files. For example e.File.ContentLength (15423 bytes), etc...

protected void fileUploaded(object sender, FileUploadedEventArgs e)

{

if (RadAsyncUpload1.UploadedFiles.Count > 0)

{

}

Because of this, I suppose, that it should be done from client side, but I don't know how.

For further information, please check the attachment.

Please help me to solve this issue.

Best regards

Vasssek

Accessibility issues (various)

Hi all,

Does anyone know of a solution to the following accessibility issues, all of which are failing the WCAG2.0 AA compliancy standards...?

Examples...

1. RadGrid Pager elements - missing "title" attribute

The PagerStyle "NextPrevNumericAndAdvanced" produces (amongst other stuff!) the following two text input fields...
- GoToPageTextBox
- ChangePageSizeTextbox

These input fields do not have the "title" attribute by default, and it's not possible for me to relate them to separate <LABEL> tags due to design considerations.

Is there any way of specifying a "title" attribute for these fields? I notice all the other links in the Pager enable this with the "xxxToolTip" attributes, but I can't find a similar attribute for the GoToPage and ChangePageSize inputs.

2. RadDatePicker (and others) - presentation tables include "summary" attribute.

Many of the controls produce tables to lay out the various components, but these layout tables include a "summary" attribute which the AA guidelines stipulate must either be not included, or contain a null value.

For example...
- RadDatePicker produces...

<table cellspacing="0" summary="title and navigation" border="0">

- RadComboBox produces...

<table summary="combobox" style="border-width:0;border-collapse:collapse;">

So, is there any way to easily customise the "summary" attribute?

Also while I'm here... the ComboBox table example above (correctly) uses "style" attribute to control the table's cellspacing and border, whereas the DatePicker uses "cellspacing=0" and "border=0", which are not recommended.

Thanks in advance,
Jon

(Note: Sorry if this has already been answered elsewhere; I've searched the forums but can't find the answer if it exists!)

Can't press "Enter" to fire Update Command when using MultiLine RadTextBox in RadGrid Edit Template.

Hi,

I have set the RadGrid Edit Mode to be "InPlace". I have also enabled the keyboard support on the RadGrid so that while in Edit mode, if I press enter after finished typing a line, the Update Command will fire. It works great in Single-Line RadTextBox, but not with Multi-Line RadTextBox, as in Multi-Line mode, when I press Enter, the caret move to the next line in the textbox instead of firing Update Command.

I tried Ctrl + Enter, Shift + Enter, Alt + Enter, but none of them can trigger the Update Command.

Please let me know if there any work-around on this issue.

Thanks

Lamk.
