Using the Chart that comes with Visual Studios I can set the Hatch Style of a particular column with the code below. I need to know how to do the same using the RadChartView.

                                this.ChtEvolution.Series[0].Points[16].BackHatchStyle = ChartHatchStyle.BackwardDiagonal;
                                this.ChtEvolution.Series[1].Points[16].BackHatchStyle = ChartHatchStyle.BackwardDiagonal;
                                this.ChtEvolution.Series[2].Points[16].BackHatchStyle = ChartHatchStyle.BackwardDiagonal;
                                this.ChtEvolution.Series[3].Points[16].BackHatchStyle = ChartHatchStyle.BackwardDiagonal;
                                this.ChtEvolution.Series[4].Points[16].BackHatchStyle = ChartHatchStyle.BackwardDiagonal;
                                this.ChtEvolution.Series[5].Points[16].BackHatchStyle = ChartHatchStyle.BackwardDiagonal;

Hi,

I am trying to make a DateTimePicker readonly and having limited success. A forum search returns a ton of candidate workarounds for this, but some of them stretch back to 2009 and it is very difficult to figure out whether these workarounds are still valid, supported, required or optimal with the latest release.

I am trying to suppress input (either keyboard, mouse, direct input or via the calendar dropdown) for a datetimepicker and the logical approach would seem to be to set the ReadOnly property to true, but this doesn't appear to have any effect.

The most common approach on the forums (from 2009 onwards) is to set the control to disabled and then fudge the styling to make it match other readonly controls, which is the approach we have taken in the past. However we are currently refactoring our control code with a view to simplifying it by removing any overly complicated hacks and fudges, so ideally this is an approach we are looking to replace.

Many of the posts recommending this approach are over 8 years old, so I am hoping this has been superseded but I am again struggling to achieve this intuitively with the latest control release.

Is there a way to set the control to readonly rather than disabled, or is the styling approach still the recommended solution?

Thanks,

Mark.

Hi, Is there any way to change the background color in some specific column when the user does click on "Add new row" text.? I can change the color after the row was added but I don't know if its possible.

Something like this.

Separately, the comboBoxs work fine, but they do not want to do it together, but at the time of loading it gives an error: an entry with this key already exists on the radGridView5.Columns [3] = comboColumn_operation ;.
Downloading occurs once

radGridView5.Invoke(new MethodInvoker(delegate ()             {                 radGridView5.AutoSizeRows = true;                 radGridView5.DataSource = _bindingSocOperationGrid;                   GridViewComboBoxColumn comboColumn = new GridViewComboBoxColumn("соц. работник");                 comboColumn.DataSource = _bindingSocRabotnik;                 radGridView5.Columns[1] = comboColumn;                 comboColumn.FieldName = "fio";                   GridViewComboBoxColumn comboColumn_operation = new GridViewComboBoxColumn("операция");                 comboColumn_operation.DataSource = _bindingSocOperation;                 radGridView5.Columns[3] = comboColumn_operation;                 comboColumn_operation.FieldName = "operation";             }));

I would like create Finical chart to update real time data, let say every 1 second. I have create a small application with CandlestickSeries type and timer to add data point to chart. i also attached my code to this post.

Questions:

- please look at video, chart keep re-render and keep refreshing. Is that a way that to prevent hold chart refreshed? (I think that Vertical Axis no need to render).

- I would like to build a chart to let use scroll back to see last hour data but on current screen i would liek to show only last 2 mins data. Is that a sample to resolve the requirements?

Please help

Regards

I have 5 Collapsible panels, all are lined up unexpanded on the right side of my screen.  When I run my program and expand the top panel, I would expect the others to move down to the bottom of the expanded first panel.

Please advise how to accomplish this

It looks like the Browsable attribute, which I use on a data model class property to hide it from the properties grid, also stops the property from being used by the Diagram control.

e.g. if my 'x co-ord' property is as below, then all my objects in the diagram have their X position at 0.

Is there a way I can either hide properties from the properties grid in another way, or make the Diagram able to use these properties regardless of being Browsable? I should think the latter, as I am explicitly telling the Diagram control to use specific properties, but that request is ignored.

Thanks

I have diagram elements that are just text, and I noticed there's a RadDiagramTextShape so I'm using that. What I'm wondering is how to set the text alignment within the bounds. Currently the text is always centered, but I'd like to set it to Left or Right also. I've seen HorizontalAlignment and HorizontalContentAlignment properties but that's the closest I could find.

Thanks.
