How to insert a table at the beginning of a new page?

created 5 years ago

Hello.
How can I insert a table at the beginning of a new page.

I use the code from the example to insert the table.

C#
if (e.VariableName == "MyCustomInsertTableField")
        {
            System.Data.DataTable dataTable = T589084.Models.MyModel.GetDT1();
            DevExpress.XtraRichEdit.RichEditDocumentServer docServer = new DevExpress.XtraRichEdit.RichEditDocumentServer();
           string PageBreak = new string('\u000C', 1);  
            int dataTableRows = dataTable.Rows.Count;
            int dataTableColumns = dataTable.Columns.Count;
            DevExpress.XtraRichEdit.API.Native.Table table = docServer.Document.Tables.Create(docServer.Document.Range.End, dataTableRows + 1, dataTableColumns);
            for (int i = 0; i < dataTableColumns; i++)
            {
                docServer.Document.InsertText(table[0, i].Range.Start, dataTable.Columns[i].ColumnName);
            }
            table.ForEachCell(delegate (DevExpress.XtraRichEdit.API.Native.TableCell cell, int rowIndex, int cellIndex)
            {
                if (rowIndex > 0)
                {
                    docServer.Document.InsertText(cell.Range.Start, dataTable.Rows[rowIndex - 1][dataTable.Columns[cellIndex].ColumnName].ToString());
                }
            });
            e.Value = docServer.Document;
            e.Handled = true;
        }
    };

Tried to do so

C#
docServer.Document.AppendText(new string('\u000C', 1));
JavaScript
richEdit.Document.CaretPosition = richEdit.Document.Range.End;

Tell me how to implement this behavior?
Thanks!

Hi Vitaliy,

You need to insert a page break before a table in the CalculateDocumentVariable event handler. Attached is an example that demonstrates how to accomplish this.
Should you have further questions, let me know.

      Hello Vitaliy,

      If a document starts with a table and a new content is inserted into the beginning of the document, this content will be always inserted into this table.

      If you need to insert your content before the table, you need to use an opposite approach:

      1. Generate the required content in an empty document using the RichEditDocumentServer API.
      2. Append content of your original document to the end of this new document.
      3. Load the resulting document into MVC RichEditControl:
      C#
      public ActionResult CustomActionRichEditPartial(string action)
{
    if(action == "insertTable")
    {
        using(System.IO.MemoryStream ms = new System.IO.MemoryStream(RichEditExtension.SaveCopy("MyRichEdit", DevExpress.XtraRichEdit.DocumentFormat.Doc)))
        {
            DevExpress.XtraRichEdit.RichEditDocumentServer docServer = new DevExpress.XtraRichEdit.RichEditDocumentServer();
            docServer.Document.Paragraphs.Append();
            //docServer.Document.AppendText(DevExpress.Office.Characters.PageBreak.ToString());
            //string PageBreak = new string('\u000C', 1);
            int dataTableRows = 5; // dataTable.Rows.Count;
            int dataTableColumns = 5; // dataTable.Columns.Count;
            DevExpress.XtraRichEdit.API.Native.Table table = docServer.Document.Tables.Create(docServer.Document.Range.End, dataTableRows + 1, dataTableColumns);
            for(int i = 0; i < dataTableColumns; i++)
            {
                docServer.Document.InsertText(table[0, i].Range.Start, string.Format("Column{0}", i)); //dataTable.Columns[i].ColumnName
            }
            table.ForEachCell(delegate (DevExpress.XtraRichEdit.API.Native.TableCell cell, int rowIndex, int cellIndex)
            {
                if(rowIndex > 0)
                {
                    docServer.Document.InsertText(cell.Range.Start, string.Format("Value{0}-{1}", rowIndex, cellIndex));
                }
            });
            docServer.Document.AppendText(DevExpress.Office.Characters.PageBreak.ToString());
            docServer.Document.AppendDocumentContent(ms, DevExpress.XtraRichEdit.DocumentFormat.Doc);
            docServer.SaveDocument(Server.MapPath("~/Documents") + "/Test.doc", DevExpress.XtraRichEdit.DocumentFormat.Doc);
            DevExpress.Web.Office.DocumentManager.CloseDocument(Server.MapPath("~/Documents") + "/Test.doc");
        }
    }
    return PartialView("_RichEditPartial");
}

      Please check the attached sample and let me know if this solution meets your requirements.
