Accept changes in RadGridView with RadEnitityFrameworkDatasource using MVVM

I am using RadGridview with RadEntityFrameworkDataSource and following MVVM pattern in a Project.
I have checked the example code in demo, and I am able to load data from entityframework.
My requirement is, the grid data to be loaded on a button click and also the grid needs to be editable with changes to be updated in table on a button click.

I know that it is possible with normal pattern, but please let me know how can it be achieved using MVVM pattern.

Scrolling from another dialog

In my application I have a scenario where the user has one window open with the PDF Viewer control and they are looking at a pdf file then my application displays a modal dialog. The user needs to be able to still scroll up/down in the PDF Viewer while this modal dialog is open. I have given them some shortcut keys to scroll a page at a time (ctrl + pg up & ctrl + pg down) and then I send these commands to the control on the other window from the modal window. This works for scrolling by a page but a lot of the time they just need to scroll a few lines. Is there any API for the PDFViewer control that will allow me to send a command to scroll up or down a few lines?

Any help on this would be greatly appreciated!!!

Thanks in advance,
Lee

Table - Merge Cells Programmatically

Hi,

How do you merge table cells programmatically?

I'm creating a table via code as customer merge field, but I need to merge my header row with with all cells within the same row so that is spans multiple columns.

I'm using library version 2013.1.220.40.

Here's my code thus far (Sorry it's quite long):

Table table = new Table();

//Payment Details Title **

Span spanPaymentDetails = new Span("Payment Details");

spanPaymentDetails.StyleName = "styleTableTitle14";

Paragraph paragraphPaymentDetails = new Paragraph();

paragraphPaymentDetails.Inlines.Add(spanPaymentDetails);

TableCell cellPaymentDetails = new TableCell();

cellPaymentDetails.Background = Colors.LightGray;

cellPaymentDetails.Blocks.Add(paragraphPaymentDetails);

//BACS

Span spanBACS = new Span("BACS:");

spanBACS.StyleName = "styleTableContent14";

spanBACS.FontStyle = FontStyles.Italic;

Paragraph paragraphBACS = new Paragraph();

paragraphBACS.Inlines.Add(spanBACS);

TableCell cellBACS = new TableCell();

cellBACS.Background = Colors.LightGray;

cellBACS.Blocks.Add(paragraphBACS);

//Bank

Span spanBankTitle = new Span("Bank: ");

spanBankTitle.StyleName = "styleTableContent14";

spanBankTitle.FontStyle = FontStyles.Italic;

Span spanBankDetail = new Span("HSBC");

spanBankDetail.StyleName = "styleTableContent14";

Paragraph paragraphBank = new Paragraph();

paragraphBank.Inlines.Add(spanBankTitle);

paragraphBank.Inlines.Add(spanBankDetail);

TableCell cellBank = new TableCell();

cellBank.Background = Colors.Transparent;

cellBank.Blocks.Add(paragraphBank);

//Account Name

Span spanAccountNameTitle = new Span("Account Name: ");

spanAccountNameTitle.StyleName = "styleTableContent14";

spanAccountNameTitle.FontStyle = FontStyles.Italic;

Span spanAccountNameDetail = new Span("My Company Name");

spanAccountNameDetail.StyleName = "styleTableContent14";

Paragraph paragraphAccountName = new Paragraph();

paragraphAccountName.Inlines.Add(spanAccountNameTitle);

paragraphAccountName.Inlines.Add(spanAccountNameDetail);

TableCell cellAccountName = new TableCell();

cellAccountName.Background = Colors.LightGray;

cellAccountName.Blocks.Add(paragraphAccountName);

//Sort Code

Span spanSortCodeTitle = new Span("Sort Code: ");

spanSortCodeTitle.StyleName = "styleTableContent14";

spanSortCodeTitle.FontStyle = FontStyles.Italic;

Span spanSortCodeDetail = new Span("22-11-33");

spanSortCodeDetail.StyleName = "styleTableContent14";

Paragraph paragraphSortCode = new Paragraph();

paragraphSortCode.Inlines.Add(spanSortCodeTitle);

paragraphSortCode.Inlines.Add(spanSortCodeDetail);

TableCell cellSortCode = new TableCell();

cellSortCode.Background = Colors.LightGray;

cellSortCode.Blocks.Add(paragraphSortCode);

//Account No.

Span spanAccountNoTitle = new Span("Account No. ");

spanAccountNoTitle.StyleName = "styleTableContent14";

spanAccountNoTitle.FontStyle = FontStyles.Italic;

Span spanAccountNoDetail = new Span("xxxx xxxx");

spanAccountNoDetail.StyleName = "styleTableContent14";

Paragraph paragraphAccountNo = new Paragraph();

paragraphAccountNo.Inlines.Add(spanAccountNoTitle);

paragraphAccountNo.Inlines.Add(spanAccountNoDetail);

TableCell cellAccountNo = new TableCell();

cellAccountNo.Background = Colors.LightGray;

cellAccountNo.Blocks.Add(paragraphAccountNo);

//Cheque

Span spanCheque = new Span("Cheque:");

spanCheque.StyleName = "styleTableContent14";

Paragraph paragraphCheque = new Paragraph();

paragraphCheque.Inlines.Add(spanCheque);

TableCell cellCheque = new TableCell();

cellCheque.Background = Colors.LightGray;

cellCheque.Blocks.Add(paragraphCheque);

//Cheque Made Payable To

Span spanChequeMadePayableTo = new Span("Made Payable To:");

spanChequeMadePayableTo.StyleName = "styleTableContent14";

Paragraph paragraphChequeMadePayableTo = new Paragraph();

paragraphChequeMadePayableTo.Inlines.Add(spanChequeMadePayableTo);

TableCell cellChequeMadePayableTo = new TableCell();

cellChequeMadePayableTo.Background = Colors.LightGray;

cellChequeMadePayableTo.Blocks.Add(paragraphChequeMadePayableTo);

//Cheque Details

Span spanChequeDetail = new Span("My Company Name");

spanChequeDetail.StyleName = "styleTableContent14";

Paragraph paragraphChequeDetail = new Paragraph();

paragraphChequeDetail.Inlines.Add(spanChequeDetail);

TableCell cellChequeDetail = new TableCell();

cellChequeDetail.Background = Colors.LightGray;

cellChequeDetail.Blocks.Add(paragraphChequeDetail);

//Add Cells To Table Row

TableRow rowTitle = new TableRow();

rowTitle.Cells.Add(cellPaymentDetails);

table.AddRow(rowTitle);

TableRow rowDetails = new TableRow();

rowDetails.Cells.Add(cellBACS);

rowDetails.Cells.Add(cellBank);

rowDetails.Cells.Add(cellAccountName);

rowDetails.Cells.Add(cellCheque);

rowDetails.Cells.Add(cellChequeMadePayableTo);

table.AddRow(rowDetails);

TableRow rowDetails2 = new TableRow();

rowDetails2.Cells.Add(new TableCell());

rowDetails2.Cells.Add(cellSortCode);

rowDetails2.Cells.Add(cellAccountNo);

rowDetails2.Cells.Add(new TableCell());

rowDetails2.Cells.Add(cellChequeDetail);

table.AddRow(rowDetails2);

//Change Cell Padding

table.CellPadding = new Padding(5, 3, 5, 3);

//Create Document & Apply Styles

RadDocument document = new RadDocument();

RadDocumentStyles.AddStylesToDocumentRepository(document);

Section section = new Section();

//Add Empty Paragraph

Paragraph paragraph = new Paragraph();

paragraph.StyleName = "paragraphMailMergeTable";

section.Blocks.Add(paragraph);

//Add Table

section.Blocks.Add(table);

//Add Empty Paragraph

Paragraph paragraph1 = new Paragraph();

paragraph1.StyleName = "paragraphMailMergeTable";

section.Blocks.Add(paragraph1);

//Add Section To Document

document.Sections.Add(section);

document.MeasureAndArrangeInDefaultSize();

return new DocumentFragment(document);

converter applied to x-axis labels

I have a categorical chart where X values are enum.
By default chart shows as x-axis labels the name of enum value.

Is it possible to insert a converter so that the label is automatically converted to a custom (localized) string?

PrintExtensions with Large Amount of Data

Kindly find the Below Code, this is the PrintExtensions Class that Prints an image of the Gridview data,
however on large amount of data, it takes maybe half an hour without doing anything and in the same time it consumes a lot of CPU memory.

but in small amount of data it works very fine.
Any solution?
