Docking 2008 Q1 SP1

In some strange cases opening a new document seems to cause repeated repainting / resizing(?) of documents that are in the background. Are there known repainting/refresh bugs? To provide a test application is probably quite complicated. I've noticed this mainly with UserDockForms that contain nested Table Layout Panels and .net UserControls.

Refreshing the chart will not showing the X-axis lables

hi,

I have drawn the Gantt chart with date on X-axis, time on Y-axis.
I have added the range of the X-Axis using the following Statement

radChart1.PlotArea.XAxis.AddRange(GraphStartTime.ToOADate(), GraphStartTime.AddDays(7).ToOADate(), 1);

I have set the Y-AxisLabel text to "XYZ".

My requirement is to change the AxisLabel text to "ABC", when the user clicks on the button.

I add the following code:
private void btnChangeAxisLabel_Click(object sender, EventArgs e)
{
            radChart1.PlotArea.YAxis.AxisLabel.TextBlock.Text = "XYZ";
            radChart1.Refresh();
            radChart1.UpdateGraphics();
            radChart1.Update();
}

It is changing the AxisLabel text to "ABC".
But X-Axis ChartAxisItem's TextBlock.Text is not appearing(i.e The dates what i have added to X-axis is not appearing).

Please share the sample code.

Using Objects as Datasources

I've recently started using DevForce for middle-tier development on my winform applications and am having difficulty binding with the Telerik GridView. I saw in the example the grid binds to arraylists but what about Generic Collections? The grid binds to all properties and I don't see a way to control that. Am I missing something?

VisbileChanged Event fired at DesignTime?

Hello,

I am having problems with the docking manager (6.0.2.0) at Design time again.

One of the Panels I am using in the docking manager has a Handler for the VisibleChanged-Event (so it fills its components with data the first time its actually visible)

This caused the visual studio designer (!!) to freeze (CPU 100%).
When I comment out the VisibleChanged Handler of the Panel , everything works fine.

At runtime both alternatives work.

So do events actually get fired at design time ?

Which DockPanel-Event should I handle if I want to intialize components (for example fill a RadComboBox with data) at runtime when they are first visible to the user.

Greetings

Value of RadMaskedTextBox is reset.

Hi,

Just want to ask if why the value of my RadMaskedTextBox is always reset to current date when ever I clicked or the cursor is on the said field.

Scenario is the RadMaskedTextBox is populated during the Load_Form event and whenever I click or put the cursor on the said field, it would reset the value to current day. Example is when the loaded data is 04/04/1980, and when I click or put the cursor on the said field, it would reset to current date, which is 06/03/2008.

Hoping for your swift reply.

Regards,
Jhun

[Solved] Shortcuts Issue

Hi, I assigned the shortcut of Ctrl + S to a btn_save_Click, and it works most of the time. However, when I run a child window, press Ctrl + S while the child has focus, and return to the parent form, the shortcut no longer works.

Thanks in advance.

Zooming On Y-axis and Vertical Line

hi,

I want to Zoom the chart along the Y-axis.

Ex:-

http://www.smartmoney.com/eqsnaps/index.cfm?story=charting&symbol=IBM

open the above link.
In that one When the user clicks on the chart and drags along X-axis, it is zooming that part. But I want to Zoom it along Y-axis (i.e when the user clicks on the Y-axis and drags the cursor, we have to zoom the chart along Y-Axis.)

One more thing is, It is showing one vertical line for all the charts.
I have charts one above the other(for all date on X-axis).
Instead of that one I want one fixed vertical line, it should have to pass through all the charts.
suppose I have a combo box. I will select one particular range in that combo box. i have to highlight that particular range data items with one vertical line
(i.e That vertical line should have to be expand, and should have to cover the data items of the combobox selected dates range).

Thanks and Regards,
chandra

Formatting problem with Grouping on Q3 2007 SP1

First of all, yes we are using Q3 2007 SP1 because we don't dare upgrade at this late point in our development.

Secondly, I have no posted screenshots yet because I am hoping this is a known issue.

Basically, we have a grid with one level of grouping and a theme applied.. everything works pefectly.. except if we scroll up and down on the grid really fast using the mouse wheel, suddenly cells start to lose their style, reverting back to the default font and color.

Using RadControlSpy confirms the cells are losing all custom styling.

Is this a known issue? If not I can create an example to upload.

Thanks,

Capstone
