CreateCellElement Event not fired on all cells displayed

Hello,

I try to use custom cells dynamically following data I want to display ( use checkbox when data is boolean). To do so I use CreateCellElement to instantiate my custom cell but it appears to this event is not fired on that specific column and the column have default display with "True" and "False" instead of check boxes.

Here is a part of my code :

this._radVirtualGrid1.CreateCellElement += onGridCellTypeNeeded;

private void onGridCellTypeNeeded(object sender, VirtualGridCreateCellEventArgs e)

{

if (e.ColumnIndex >= 0 && e.RowIndex >= 0)

{

DataType type = myDataDescriptor.getDataType(e.ColumnIndex);

switch (type )

{

case DataType.Bool:

e.CellElement = new CheckBoxCellElement(e.ColumnIndex);

registerCustomColumnIfNeeded(e.ColumnIndex);

break;

}

Do you know how to fix it ?

Regards,

Amand.

RadListView list items horizontally

Hi

I have a radlistview being populated manually in iconview mode. However when the list has more items then the display area it automatically creates new rows therefore the scrolling happens vertically.

I am sure there is a way to change it so items go in one row and the scrolling is horizontal but so far I have to failed to find it.

Any help would be appreciated.

Different Editors

Hi,

I have a gridview with two columns.

this.radGridDettagli.MasterTemplate.Columns.Add(newGridViewTextBoxColumn("Name", "Name"));
this.radGridDettagli.MasterTemplate.Columns.Add(new GridViewTextBoxColumn("Value", "Value"));

The column "Value" could contains different object types. Decimals, String, Date, Enum, etc, ect.

I would like, to use different editors based on the cell value of my column "Name".

Example

Cell value of column "Name" is "ExpiryDate" I need RadDateTimePicker to edit the cell "Value" or the same row
Cell value of column "Name" is "Quantity" I need RadSpinEditor to edit the cell "Value" or the same row
Cell value of column "Name" is "OrderState" I need RadDropDownList to edit the cell "Value" or the same row

RadSpinEditor for numbers, RadDropDownList in case of Enum, RadDateTimePicker in case of Date, RadTextBox in case of string.

Somebody could help me ?

Thanks.

Rendering

Hello,

I was wondering if anyone could help me set the rendering of text and graphics of my radchartview to antialiasing? I know there is a enum called TextQuality, but I am not sure how to access it.

Thank you,

Reordering Columns

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,

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();
