Options in DataFormComboBoxField

Hello,

I am trying to implement a RadDataForm using a DatFormComboBoxField. Following this section of documentation: http://docs.telerik.com/devtools/wpf/controls/raddataform/how-to/raddatafor-edit-lookup-values-with-radcombobox

I have been unable to produce results.

I stumbled across the ability to use an enum within a class to allow all of the enum's values to be combo box items. Sadly, as our combobox options will be changing based on our database, this won't be an effective solution. Are there any similar methods to add options to a combo box (dictionary, json object, etc)?

This has been a struggle for a few days now, any help is greatly appreciated...

Customizing Selection Behaviour

Is there a way to customize how selection works in the RadRichTextBox. We have an application where we would like to restrict certain AnnotationRanges from being selected. I am aware of the IsCopyable property on annotation ranges, but I am specifically looking for the ability to restrict selection as opposed to restricting copying.

In addition to this, we make use of tables and when selecting the contents of a cell we would like to be able to restrict the selection to the cell contents and not allow the cell itself, the table row, or the table to be selected.

Is there any functionality that allows us to override this behaviour or see what selection is about to be made and change it before it is made?

Thanks.

Open XLTX with IWorkbookFormatProvider

Hi there,

i'm using the IWorkbookFormatProvider to open an XLSX, modify some values and save it under another name. Works fine.

Is it also possible to open an XLTX (Excel Template) File with the IWorkbookFormatProvider? That would be the much nicer solution than opening a XLSX and save it under another name. If i just change the source of for the FormatProvider to an .xltx an error is thrown.

Thanx for your help.

[Solved] Changing of LinearAxis.MajorStep property doesn't affect the axis.

Hello. I'd like to change Y-axis scale for RadCartesianChart with BarSeries. I do the following for it: 1) Define the property that is binding data source.

/// <summary>

/// Step (selected by a user) for vertical axis.

/// </summary>

private double _currentStep;

/// <summary>

/// Gets or sets the step (selected by a user) for vertical axis.

/// </summary>

private double CurrentStep

{

get { return this._currentStep; }

set { this.SetProperty(ref this._currentStep, value); }

}

2) Use the property in binding in XAML (here I don't display all XAML but if you need I'll do it):

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis x:Name="verticalAxis" Title="Percents [%]" Minimum="{Binding ChartMinimum}" Maximum="{Binding ChartMaximum}" MajorStep="{Binding CurrentStep}"/>

</telerik:RadCartesianChart.VerticalAxis>

As you can see I also set Minimum and Maximum properties here.

3) I assign MajorStep, Minimum and Maximum properties by the values I've got from modal dialog:

private void raiseScalingMinMaxInputWindow()

{

InputScalingValuesNotification inputScalingValuesNotification = new InputScalingValuesNotification();

inputScalingValuesNotification.Title = "Set the scale";

this.InputScalingValuesConfirmationRequest.Raise(inputScalingValuesNotification,

returned =>

{

if (returned != null && returned.Confirmed)

{

this.ChartMinimum = (double)returned.MinimalScalingValue;

this.ChartMaximum = (double)returned.MaximalScalingValue;

this.CurrentStep = (double)returned.MajorStepValue;

}

});

}

I've checked in debugger so values are assigned correctly. Eventually, LinearAxis.Minimum and LinearAxis.Maximum properties are set correctly but LinearAxis.MajorStep is not set. If you open Scale.PNG file attached you can see the example of it. There I set LinearAxis.Minimum == 1, LinearAxis.Maximum == 12 and LinearAxis.MajorStep == 1. But the value of LinearAxis.MajorStep there is equal to 2. Why does it have place? And the second, why do not all fit in the scale window? So I need that the MajorStep must match the specified value (for example 1 in our case) and all Y-axis scale fits to the window size and not to go outside the window.

May be I do something wrong? May be I should use LinearAxis.ActualRange property instead of LinearAxis.Minimum and LinearAxis.Maximum properties? Please tell me and help me. As always, I will be very grateful to you.

Select cell content when readonly

Hi,

I have a RadGridView with CanUserSelect="True". I define my columns manually using nested GridViewDataColumn. Each column is bound to some property of some object. The properties only have a 'get' method. When i run my app, I cannot select the content of the cells (for copy operation). I noticed that if i change the properties of the underlying objects and add an empty setter, I get to edit.

How can I do the same things without having to change my properties? I want to be able to have readonly data that I CAN select. Is there a way to tell the columns or the whole grid that they should be selectable? (I thought btw that 'CanUserSelect' should take care of that?)
