I find that if I have EmptyValue.Mode set to Approximation, I get undesired results in my graph if I have multiple values missing in a row. For example, if I have these consecutive values in my series:

1, 2, <empty>, <empty>, <empty>, 3, 4, 5

The dotted line looks like it is using:

1, 2, 2.5, 2.5, 2.5, 3, 4, 5

In this series, I would expect the approximation to result in, or even just 1, 2, 3, 4, 5:

1, 2, 2.25, 2.50, 2.75, 3, 4, 5

I would actually like to ignore those three data points entirely.. Consider this data:

0.05     1     5
0.10     2
0.15
0.20            6
0.25            7
0.30     3
0.35     4
0.40     5     9

I essentially want the empty fields to be ignored for each ChartSeries, or approximated better than I described above (2.5 for all three missing values in the second column). Is there a mode I can set in the approximation that I'm missing, or is what I'm getting the only possible behavior? The only two EmptyValue modes I see are "Zero" and "Approximation", neither of which do what I want.

Thanks,

I have a form (parent) that instantiates a DocumentWindow object which adds a child form (documentWindow.Controls.Add(childForm)) and sets the autoscroll property to true (documentWindow.AutoScroll = True).  I am trying to figure out how to bring focus to this control. 

How can I set focus to a DocumentWindow's scrollbar through code?

Thanks,

Hi,

I was wondering if there is an article or section that contains documentation to create your own GridViewDataColumns as well as IInputEditors.  I've tried searching the forums and the library's documentation but certain classes/interfaces don't even have a complete reference texts.

For each row I add in the GirdView, I set a tag like this

GridViewDataRowInfo row = aGridView.Rows.AddNew();
row.Tag = 1;

RadGridView.Rows.Add(row);

and when I click on a row in the Girdview, I want to get the associated tag to the selectedrow.

The problem is that RadGridView.SelectedRows[0].tag is always null.

I found out that RadGridView.SelectedRows[0] return a GridViewRowInfo and not a GridViewDataRowInfo.

Is there a quick way to have the tag of the GridViewDataRowInfo object of the selectedrow ?

 

I set up a datagridview, it contains 6 columns, 2 buttons, 2 fields, and 2 comboboxes, when I link the LinqToSql datasource to the datagridview's datasource it loads the fields I defined, and then appends all the fields in the database table to it as well dynamically.  Any thoughts on why this might be happening, and more importantly, how do I fix it?

Thank you in advance,
Jim

Hi

I have an MDI Parent (inherits from RadRibbonForm) and an MDI Child (RadForm).

The application programmatically sets the state of the window using the following code :



When this code is called in the Form_Load event, or in the Form constructor after InitializeComponent(), and the child form does not show correctly, the top 20 odd pixels are hidden behind the Ribbon Bar.

If the same code is called from the Form_VisibleChanged event, then the behaviour is normal.

I can use the VisibleChanged event as a work around, but think that this is a bug and would like to report it.

I would also be interested in knowing if you feel this code should be called from somewhere other than the constructor or form_load.

I am using v2009.2.9.729 of the controls.

I would like to use the carousel control in a touch-screen application.  My users would like a 'pause/go' button - something more visual - and I'm not sure the best way to simulate the AutoLoopPauseCondition.  At this point, I've simply set EnableAutoLoop on/off with the click of the button.

Is there a better approach?

Hello,
We are building an application where we need to add radscheduler but before we do that we had few questions, the first one is does radscheduler have reminders and 2nd does radscheduler support multi user like (http://www.devcomponents.com/dotnetbar-wpf/WPFScheduleControl.aspx). And the 3rd one is where we need to replace the days on x-axis with people's name and the whole calendar becomes one day (which we are calling group calendar). Please let us know if this is possible.
Thanks

I have version 2009.2.9.729 for Winforms installed.  Doing a save layout as a file works great.  It's a valid xml file that can be read ok.  However the need is to save the xml to sql.  Straight forward to do using XmlWriter.  However, doing this the closing tag </RadGridView> is missing.  I've worked around this by appending it to the xml string.  After changing the encoding to utf-16 it saves to sql fine.

Either I'm doing something wrong or is this a bug?

Thanks..Bill
