RadBrowseEditor that accepts file OR directory

Hi,

I'm in a need for a dialog form that in the end returns a FilePath OR a DirectoryPath, with a TextBox that the user can paste something (file or directory).

I tried doing so with a System.Windows.Forms.FolderBrowserDialog but without success.

I'm turning over Telerik, found the RadBrowseEditor and calling the RadBrowseEditor .BrowseElement.BrowseButton.PerformClick() method for opening.

The best/closest DialogType is BrowseEditorDialogType.OpenFileDialog, but the problem is when pasting a DirectoryPath, the control navigates there and no event is raised (same as the system's FolderBrowserDialog, it's even the same used from Telerik).

I tried listening to events ValueChanging and also all those under the BrowseElement object, but nothing works.

Any idea (I didn't want to create a new form, developping the navigation treeview, textbox, since almost everyhing is there)?

thanks

Secondary Axis without data series

Hi,

I would like to add a secondary x-axis to my chart (having relative instead of absolute values) without a belonging data series. But I have problems to get this axis shown. With the following code, the axis is simlpy not shown:

// Secondary x-axis with percent values of current price

LinearAxis horAx2 = new LinearAxis();

horAx2.VerticalLocation = AxisVerticalLocation.Bottom;

horAx2.Minimum = Math.Round(_minX / ulPrice, 4);

horAx2.Maximum = Math.Round(_maxX / ulPrice, 4);

horAx2.MajorStep = Math.Round(ulPrice * 0.03 / ulPrice, 4); // 0.05; // 1 Prozent gerundet //Convert.ToInt16(units)*10;

horAx2.Font = new System.Drawing.Font("Ubuntu", 10F, System.Drawing.FontStyle.Bold);

Is it possible to a secondary axis without a complementay data series?

Thank you

Changing TitleBar colour of a RadForm

Hi,

I'm in the process of evaluating your winform controls and I'm trying to emulate the way the demo app hub changes the title bar of a form, size and colour. For example when selecting the Grid Example the header is about 80 high, dark blue with a back button.

The app I created has a simple Radform and Rad Data View, on load I try to change the TitleBar, but I must be doing something wrong.
I can change the background colour but the background of the system buttons stay the same.

Here's a snippet
this.FormElement.TitleBar.Size = new System.Drawing.Size(this.Width, 100);
this.FormElement.TitleBar.FillPrimitive.BackColor = Color.DarkBlue;
this.FormElement.TitleBar.CloseButton.ImagePrimitive.BackColor = Color.Transparent;

I has also tried to create a new RadTitleBarElement, but the out come is the same.

I know I'm missing something simple here so can you point me in the right direction?

Cheers
Shaun.

How to disable DatePicker's auto completion with typing

I have a DatePicker (not DateTimePicker) and want to add functionality to it. If I type "t" it displays today's date. This part works, but I also want to add t-n/t+n where n is the number of days to add or subtract from today's date. However, whenever you type a number into a DatePicker, it automatically assumes the same month and year and outputs whatever number you type as the date. For example if i type t+4, and today's date is 11/20/2018, it displays 11/4/2018, even though, through debugging, it does hit the line that should display 11/24/2018. It appears to run OnValueChanging a second time, imputing what telerik thinks I want. Is there anyway to disable this, or cancel it once it starts?

Modify selection contents

Let's say I want to give my user the ability to select some text and convert it to some other text, for instance to mangle it with ROT13 cipher. And selection could be made of several ranges, including in table cells. How would I go about this? My first idea was something like the code below, but some kind of update is required, because I only see the change if I scroll the text out view and back in, and even then the changed text does not reflow, but it continues after the right margin. Also, ability to undo the changes would be nice.

foreach (var inlineLayoutBox in radRichTextEditor1.Document.Selection.GetSelectedBoxes())

{

if (inlineLayoutBox.Text.Contains('e'))

inlineLayoutBox.Text = inlineLayoutBox.Text.Replace("e", "3333333");

}

Radgridview does not update until row move!

Hi everyone.

I have this issue, and i'm trying to deal with it for the last 3 days now, no solution found.
My grid is loaded using an DataAdapter.

When I edit the items in the grid,and fire the update command, the data in my database will not be updated.
This is until i move the grid one row. Then it will accept changes made. So i'm struggeling here to find a way out.

Could you please provide me some sample or solution for this?
Btw, i'm using VB.NET for this.
