c1maps: Bing Map tiles are not cached (bug?)

freds72 — Tue, 07 Sep 2010 10:02:02 GMT

Looking at a Fiddler trace, I see that tiles are re-requested between each application run.

WPF Studio (evaluation) version is: 3.0.20102.101.

I would have expected the tiles to be cached in the IE (or .Net HTTP) cache.

Is caching to be activated in code (if so, I could not find the right entry point) or a missing feature?

C1DataGrid : disable redrawing of the grid by code, in order to avoid scrolling visual issues while positionning the row inside the grid.

loponionf — Tue, 07 Sep 2010 07:39:36 GMT

I would like to know if it is possible to disable redrawing of the grid by code, in order to avoid scrolling visual issues while positionning the row inside the grid.

The reason i'd like to avoid redrawing, is that i position the row on the first line when i sort or group.

On the event "SortChanged, i use a timer"

In this timer, i find the row in wich i was positionned (it is the variable l_objRowData)

and then i position it on the first line of the grid :

A s you can see by code, i scroll into the view the first time. And on the next UI Thread, i ensure myself to put the row on the first position (if possible)

The variable : l_NbLignesGrid corresponds to the number of visible rows on the screen.

The problem with this solution, is that the UI shows the scrolling for the 2 scrollintoview.

Validate C1NavigationListInputItem

MiamiLux — Tue, 07 Sep 2010 05:55:49 GMT

I found this example how to validate a C1NavigationListInputItem
http://demo.componentone.com/iphone/LiveExamples/Login.aspx

Is there any documentation for this sample?

I had to look at the source of the HTML in order to get some parts working.

It would be nice if we could get documentation for all the examples.

FlexGrid SubTotals issue

Dan — Tue, 07 Sep 2010 05:32:47 GMT

Hi,

Am using the FlexGrid.SubTotals() methos as per the Subtotals sample, but am gettgin some strange behaviour. Basically, the fourth level of grouping is not grouping correctly.

My code is:

_flex.Subtotal(AggregateEnum.Clear);

_flex.Tree.Column = 1;

    _flex.Subtotal(AggregateEnum.Sum, 0, -1, transAmtCol, "Grand Total");
    _flex.Subtotal(AggregateEnum.Sum, 1, classCol, transAmtCol, "Class Total for {0}");
    _flex.Subtotal(AggregateEnum.Sum, 2, acctTypeCol, transAmtCol, "Account Type Total for {0}");
    _flex.Subtotal(AggregateEnum.Sum, 3, transTypeCol, transAmtCol, "Transaction Type Total for {0}");

where classCol, acctTypeCol, transTypeCol & transAmtCol are 1, 2, 5 & 40 respectively.

The behaviour I get is the grouping at level 3 does not match the Transaction Type column (see screenshot attachment). As you can see, it has produced a series of sub totals for Transaction Type of Fee. Looking closer, the grouping appears to follow the Transaction ID column - but, when I set the values in this column to null, the grouping does not change. What am i doing wrong?

NOTE: have moved columns in the screenshot so relevant columns are all visible.

IsTabStop and selectable C1ComboBoxes

csmall — Mon, 06 Sep 2010 15:31:03 GMT

We're trying to emulate the combobox you get in a browser (the standard windows forms control behaviour) where using the keyboard selects the first item it finds in the combobox, and arrow keys open the combobox.

We've got quite a few c1ComBoBoxes on a user control - the standard Silverlight ComboBox doesn't support the two behaviours mentioned. However we don't want the comboboxes to be tab-able, but you need to be able to select one, press a key to select an item, click the next box and continue.

Here's a demo: http://jsfiddle.net/qMCpg/ in HTML (click and press 2, then click the next item).

The problem we have is the C1ComboBox doesn't allow the keyboard to be used if IsTabStop is false.

headings with multiple columns in report

HMaster — Mon, 06 Sep 2010 15:22:22 GMT

We are using the C1PrintPreview control and creating reports in code.

We would like to create a report with this style of page layout:

-----------------------------------------

My Section Heading accross the page

Item 1                           Item 6
Item 2                           Item 7
Item 3                           Item 8
Item 4                           Item 9
Item 5                           Item 10

My Second section heading

Item A                           Item D
Item B                           Item E
Item C                           Item F

-----------------------------------------

That is, using the columns option create sections whereby the data (probably a RenderTable) is rendered into columns, but with a heading that is not also "squashed" into the columns too.

Is such a layout possible, and if so, how?

Thank you.
Nick.

Simple example of C1Uploader with PHP script on server?

Tom — Mon, 06 Sep 2010 14:43:44 GMT

Is there a simple example of sending a string using C1Uploader to a PHP script?

I currently use UploadStringAsync, which works fine, but the string is now so long that I need a progress bar, and the progress indicator I get from UploadProgressChangedEvent only fires at 50% and 100%.

This is what I tried with C1Uploader:

public void uploadFile(string[] keys, string[] values, string URL, fromGetData returnCall, string file)

{

returnData = returnCall;

string parameters = "";

for (int i = 0; i < keys.Length; i++)

{

if (parameters.Equals(""))

parameters = parameters + "?" + keys[i] + "=" + values[i];

else

parameters = parameters + "&" + keys[i] + "=" + values[i];

}

Random random = new Random();

parameters = parameters + "&Unused=" + random.Next().ToString();

URL = URL + parameters;

Uri uri = new Uri(URL);

C1Uploader uploader = new C1UploaderPost(uri);

Encoding utf8 = Encoding.UTF8;

byte[] utf8Bytes = utf8.GetBytes(file);

MemoryStream ms = new MemoryStream(utf8Bytes);

uploader.UploadProgressChanged += uploader_UploadProgressChanged;

uploader.UploadCompleted += uploader_UploadCompleted;

uploader.AddFile("mydata", ms);

uploader.BeginUploadFiles();

}

Thanks

Curves on the chart wouldn't clear.

sergeyzuev — Mon, 06 Sep 2010 14:19:27 GMT

Hello! I want to clear all the curves from the chart. I tried something like this:

this.mainChart.BeginUpdate();

this.zoomChart.BeginUpdate();

this.mainChart.Data.Children.Clear();

this.zoomChart.Data.Children.Clear();

this.mainChart.EndUpdate();

this.zoomChart.EndUpdate();

Unfortunately, it didn't work correctly. Dataseries were deleted, but PlotElements didn't and they are still visible. They are not only visible, but there are still their objects in the memory.

What can be done about it? Thanks in advance!

P.S. I'm aware of Reset method, but after this.mainChart.Reset(true) I have to customize axes and so on. Is there any better way?

ChartEditor can’t edit and remove ChartLegend added in XAML

dopydo — Mon, 06 Sep 2010 12:21:04 GMT

I attached sample solution.

It contains 2 charts and 2 chart editors.
- First Chart has ChartLegend and ChartEditor can’t remove/edit it.
- Second Chart doesn’t have legend. ChartEditor can add it and then edit/remove.

Do I use correct way to add chart legend? It looks like ChartEditor has other way.

<chart:C1Chart x:Name="chart1" Grid.Column="0" Grid.Row="0" ChartType="Pie" Width="400" Height="400">
            <chart:C1Chart.Data>
                <chart:ChartData>
                    <chart:DataSeries Values="1,0,2,4,5,2" Label="s1" />
                </chart:ChartData>
            </chart:C1Chart.Data>
            <chart:Legend />
        </chart:C1Chart>
<chartEditor:ChartEditor Grid.Column="1" Grid.Row="0" DataContext="{Binding ElementName=chart1}"/>

Performance on 100Hz live signal

juergen.andres3 — Mon, 06 Sep 2010 07:50:53 GMT

Hey,

I'm testing the ComponentOne chart to display a 100Hz live signal. The charts are really good looking but i get a CPU load of 80 to 90% and the user interaction is totally blocked. Is there a way to decrease it ?

I'm using three XYPlot charts on a window, each one is binded to an ObserveableCollection of a ViewModel.

<c1chart:ChartData ItemsSource="{Binding ChartViewModel.DataPointCollection, Mode=OneWay}">

The ObserveableCollections get new Points added with 100Hz over a time of 3 to 5 minutes. I tried SetOptimizationRadius(this.Chart, 2.0) but it brought no success!

Natural looking toolbar buttons

LinusDillon — Mon, 06 Sep 2010 07:18:18 GMT

Hi,

We recently purchased Studio for iPhone and so far qre very happy. However one issue I have run into and have spent a fair chunk of time on trying to solve is how to create useable toolbar buttons in a view port which resemble those used elsewhere in iOS.

I can create suitable looking buttons using normal HTML style images in the tollbar area, however their onclick and/or URL properties do not then seem to work.

I can also create working buttons using the Studio for iPhone button and segmented button controls, however these do not look anything like normal toolbar buttons. My attempts to style these using CSS and custom style to match have largely failed (I am admitidly weak in this area).

We are using Studio for iPhone version 4.0.20102.112.

Any help welcome, examples particularly.

why do not implement the same behavior with ado.net dataset in c1.silverlight.data.dll

szbluesky — Mon, 06 Sep 2010 03:36:22 GMT

1. why do not implement the same behavior with ado.net dataset in c1.silverlight.data.dll

in silverlight client we must use:

ds.GetChanges(DataRowState.Deleted);

to get the delete record, cannot use the same behavior with ado.net: (rowState)

            foreach (DataRow dr in ds.Tables[0].Rows)
            {
                if (dr.RowState == DataRowState.Deleted)
                {
                    // to do
                }
            }

and the DataTable in silverlight don’t contain the deleted data now, so I send to the server has no deleted data.

How can I get a data copy that contain all data in a single table：unchanged, deleted, modified, AddNew ?

I want to send whole data to the server side, because I will use the all data to process some busineslogic？

· 2. and the 2nd question:

how to copy and clone a dataset&dataTable in c1.Silverlight.DataSet

Has no public method: Row.Copy, DataTable.Copy, DataSet.Copy

Another way I can copy a dataset , then append the deleted data to the source dataset:

            DataSet ds2 = ds.GetChanges(DataRowState.Deleted);
            foreach (DataRow dr in ds2.Tables[0].Rows)
            {
                dr["__RowState"] = -1;
                ds.Tables[0].Rows.Add(dr.ItemArray);
            }

but I cannot modify the original dataset, So I want to copy the Orignal dataset, but no public method for copy.

I want to copy a table,but the RowState is a private method:

DataTable table = new DataTable(src.Name);
    table._columns =src.Columns;
    table.PrimaryKey =src.PrimaryKey;
    foreach (DataRow row in src.Rows)
    {
        if (((byte) (row.RowState & state)) != 0)
        {
            table.AddRowClone(row).SetRowState(...)

        }
    }

How to get rid of evaluation popup message for C1Report

MASchaefer — Sun, 05 Sep 2010 20:02:00 GMT

I cannot get rid of the evaluation popup box when my code executes the following:

Dim subrptweb1 As New C1.C1Report.C1Report

I normally get rid of the popup messages by dragging the control onto a web form, thus adding the token to the licenses.licx file.

How do I do this for the C1.C1Report dll? As far as I can tell, there is no control that I can drag onto a web form.

Thanks,

Two questions. Add event Link support C1SuperTooltip ? Use C1SuperTooltip and C1TopicBar ?

GigaZiv — Sun, 05 Sep 2010 10:14:51 GMT

1. It would be nice if you could add support for links, like an event that is fired if the mouse hovers over a link and another event that is fired if the user clicks on a link. Very much it would be desirable to see this functional !!!

2. What event to use in C1TopicBar for Link item (in Page Collection) to call C1SuperTooltip ?

Thanks!

C1DataPager and Ria Services

gregoryagu — Sat, 04 Sep 2010 03:23:44 GMT

OK, so I am trying to implement Server Side Paging. I have this part working fine using skip and take and bundling it all up in a PagedCollectionView. I then bind this view to a C1DataPager. This works fine, except that the total number of items is the local item count, not the server count.

I know how to get the TotalItemCount on the query, but I don't see how to bind that to the DataPager. If I could bind that property to my ViewModel, then it would reflect the server data. But the DataPager Item count is read only, so it cannot be set.

Once that is done, then I would just need to handle the PageIndexChanging to fetch the next page. I am not using the DomainDataSource.
