I'm new to the Virtual Grid. I can't seem to figure out how to allow the user to reorder the columns. Because the columns are built based on the OnCellValueNeeded event, I assume the reordering will have to be done here. But how can I show the dragging of a column and detect where it was dropped?

Hiding columns with a size of 0 leads to weird display

Hello,

I am trying to implement a hide/show option on column. For now, I implemented a contextual menu option to do it and as a workaround I set column size to 0 to hide it but it leads to weird display (cf attached image (with 10 hidden columns)). Do you know a better workaround to avoid this display ?

Regards,

Amand

Change zoom level to fit two pages.

I am working on a template editor, so I have a simple layout with a RadGridView on the left, and a RichTextEditor on the right. When the row gets changed, I load a template into the the RichTextEditor. The editor is readonly (the template is edited in a different window). How can I change the zoom level to automatically show two full pages.

Here's what I have when I load the template the first time http://i.imgur.com/a8vyyov.png
And here's what I can see when I hold ctrl and use the mousewheel to zoom in 1 level. http://imgur.com/angvElk.png
I am looking for something in the middle, where I can see 2 pages, and it takes up 100% of the space available.

Thanks!

How do I programatically select a tab in RichTextEditorRibbonBar?

I am adding a new tab to the RichTextEditorRibbonBar like this:

var lblTempalteName = new RadLabelElement() {

Text = "Template Name:",

AutoSize = false,

Size = new Size(120, 20)};

var tbxTemplateName = new RadTextBoxElement() {

Size = new Size(100, 25),

Padding = new Padding(2) };

var templateNameGroup = new RadRibbonBarButtonGroup();

templateNameGroup.Items.AddRange(new RadItem[] { lblTempalteName, tbxTemplateName });

var lblDataSource = new RadLabelElement() {

Text = "Data Source:",

AutoSize = false,

Size = new Size(120, 20)};

var ddlDataSource = new RadDropDownListElement() {

Size = new Size(100, 25),

DropDownStyle = RadDropDownStyle.DropDownList };

var dataSourceGroup = new RadRibbonBarButtonGroup() { Margin = new Padding(0, 3, 0, 0) };

dataSourceGroup.Items.AddRange(new RadItem[] { lblDataSource, ddlDataSource });

var rbgProperties = new RadRibbonBarGroup()

{

Text = "Properties",

Orientation = Orientation.Vertical

};

rbgProperties.Items.AddRange(new RadItem[] { templateNameGroup, dataSourceGroup });

var templatePropertiesTab = new RichTextEditorRibbonTab() { Text = "Template properties", IsSelected = false};

templatePropertiesTab.Items.Add(rbgProperties);

richTextEditorRibbonBar1.CommandTabs.Add(templatePropertiesTab);

The tab that I am adding becomes selected, which isn't what I want. How do I ensure that the "Home" tab is selected. Here's what I tried, but it doesn't work.

foreach (RibbonTab item in richTextEditorRibbonBar1.CommandTabs)

{

item.IsSelected = (item.AccessibleName == "Home");

}

richTextEditorRibbonBar1.Refresh();

Themes offered by other vendors

Can themes be viewed and purchased by other vendors that can be used with the Telerik UI? In particular, I like the theme used with ADOBE Photoshop...can this be purchased?

Treeview High DPI Support

Hi,

I'm playing around with DPI awareness. Most things scale as expected (the grid for example) but it seems to me that the Treeview does not size the items according to the Font (the font scales as I would expect but gets truncated, the height of the listitems seems to be unchanged). What am I missing?

Regards

RadCarousel Setup

I have just downloaded the WinForms UI (30 Day Free Trial) and have been experimenting with the Carousel. First, I want to use a background image in the Carousel or the Form; how do I turn off the gradient used in the carousel. I tried setting backcolor to transparent with no effect.

Second, I would like to create the same layout used in one of the Telerik Demos (See attached image). How can I accomplish this?

Last, I am using Visual Studio 2015 and I am unable to open many of the downloadable demos...including the demo for the Carousel!!! I have spent a frustrating three hours trying to adjust settings without the correct results.

I'm not sure I want to invest in a package without available help. I was able to view some Carousel videos on YouTube, however the information I was looking for was not mentioned. Please help.

Grid auto code generation

Hi,
I need to create a custom user control which contains a grid and some other components, the grid is a public property of the panel.
When i drop the panel on the form and use the grid property to create columns everything is fine, but suddenly i realized the form is not generating added column's code in designer.cs, and after build there is no column left in my grid.
So, my question is how can i force form to generate the columns code?
Tnx

Context Menu for RadChartView

Hello,

I was wondering if it is possible to use the Context Menu on a Line series radchartview? I want to be able to right click on a Line series within the chart and open up a context menu that corresponds to that line and I also want to be able to do the same thing on the legend except with a separate context menu.

Any ideas?

Thank you,

Erkin

VirtualGridDropDownListEditor crash on alpha numeric key pressed

Hi,

Aft

After experiencing a crash when pressing any alpha-numeric key on a cell containing a VirtualGridDropDownListEditor, I spotted an error in Telerik source code at file RadGridView\VirtualGrid\Input\VirtualGridInputBehavior.cs (around line 1441) :

protected virtual bool HandleAlphaNumericKey(KeyPressEventArgs keys)

{

...

else if (this.GridElement.ActiveEditor is VirtualGridDropDownListEditor)

{

string symbol = keys.KeyChar.ToString();

RadDropDownListEditor editor = this.GridElement.ActiveEditor as RadDropDownListEditor;

RadDropDownListEditorElement element = editor.EditorElement as RadDropDownListEditorElement;

if ((element.AutoCompleteMode & AutoCompleteMode.Append) == AutoCompleteMode.Append)

{

...

The editor variable should be cast as VirtualGridDropDownListEditor

Just to let you know for next releases
Sorry if bug has already been spotted and fixed :)

Regards
