Next[UP] and Previous[Down] Button in ListView

In This Example we can Traverse the listview item up and down or Next and Previous.
Lets Start Step by Step.

Step 1 : Creating a Window Application.

Step 2 : Drag and Drop 3 Controls in Default page from Toolbox
1- ListView (Name=”listView1″)
2- Button (Name=”btnUP”,Text=”UP”)
3- Button (Name=”btnDown”,Text=”DOWN”)
Step 3: double Click on Up and Down Button for Generate the Click Event

Step 4 :Create function for Fill the list View

private void BindListView()
{
string[] array = { “ListItem1″, “ListItem2″, “ListItem3″, “ListItem4″, “ListItem5″, “ListItem6″ };
var items = listView1.Items;
foreach (var value in array)
{
items.Add(value);
}
}

Step 5: Do Code for Up and Down Button

// UP Button
 private void btnUP_Click(object sender, EventArgs e)
        {
            int index = listView1.SelectedItems[0].Index;

            if (index < listView1.Items.Count - 1)
            {
                listView1.Select();
                listView1.Items[index + 1].Selected = true;
                btnDown.Enabled = true;
                if ((index = listView1.SelectedItems[0].Index) == listView1.Items.Count - 1)
                    btnUP.Enabled = false;
            }
            else
                btnUP.Enabled = false;
        }
// Down Button
        private void btnDown_Click(object sender, EventArgs e)
        {
            int index = listView1.SelectedItems[0].Index;
            if (index > 0)
            {
                listView1.Select();
                listView1.Items[index - 1].Selected = true;
                btnUP.Enabled = true;
                if ((index = listView1.SelectedItems[0].Index) == 0)
                    btnDown.Enabled = false;
            }
            else
                btnDown.Enabled = false; 
        }

Send XML to Procedure and Insert into DATABASE

SomeTimes we have Requirements to insert xml to Database.for this we send the whole xml file as parameter to store procedure.
Lets Start insert Xml Data to Database Step By Step.
for Example we have a sample XML which we want to insert into table.

<Table>
   <Rows fileno="1" filetype="txt" pagecount="10">
    <filename>txtfilename</filename>    
    <source>txtfilesource</source>
  </Rows>
  <Rows fileno="2" filetype="pfd" pagecount="15">
    <filename>pdffilename</filename>
    <source>pdffilesource</source>
  </Rows>
</Table>

Step 1: Create the Table

Create Table tblDemoTable
(
sno   int  identity(1,1),
fileno int,
filetype varchar(10),
pagecount int,
filename varchar(50),
source varchar(50)
)

Step 2: Create Store Procedure

Create PROCEDURE usp_insertXmlToDb
@Xmldata xml
AS
BEGIN
DECLARE @idoc int
EXEC sp_xml_preparedocument @idoc OUTPUT, @xmldata 


 INSERT INTO tblDemoTable                                                                                               
      SELECT                                       
      fileno                                                              
     ,filetype                                                    
     ,pagecount                                                                        
     ,filename                                                                        
     ,source                                                                                                                                             
FROM   OPENXML (@idoc, '/Table/Rows',2)                                                      
     WITH ( fileno int '@fileno',                                                        
     filetype       varchar(10) '@filetype',                             
     pagecount  int '@pagecount',                                                        
     dt  varchar(150) '@dt',                                                                                                              
     filename varchar(50) './filename/text()',                                      
     source varchar(max) './source/text()'                                                                                                            
    )                                            
EXEC sp_xml_removedocument @idoc 
END

Step 3: Execure the Store Procedure

usp_insertXmlToDb'<Table>
   <Rows fileno="1" filetype="txt" pagecount="10">
    <filename>txtfilename</filename>    
    <source>txtfilesource</source>
  </Rows>
  <Rows fileno="2" filetype="pfd" pagecount="15">
    <filename>pdffilename</filename>
    <source>pdffilesource</source>
  </Rows>
</Table>'

Step 4: check the Table Data

select * from tblDemoTable

Create XML File at runtime using CSharp

There are many advantages to using XML for information exchange, and they offer many benefits to the user.
In this Example i am describing how to Create a Xml file dynamically using C#.

Step1
Create a function for generating Xml Document

// xmlpath = D:/xmlfolder
   private void CreateXmlFile(string xmlpath)
        {
            string xmlfilepath = xmlpath + @"\" + "xmlsample.xml";
            if (!System.IO.Directory.Exists(xmlpath  + @"\"))
            {
                System.IO.Directory.CreateDirectory(xmlpath  + @"\");
            }
            if (!System.IO.File.Exists(xmlfilepath ))
            {
                using (var file = System.IO.File.Create(xmlfilepath)) ;
            }
            using (XmlTextWriter myXmlWriter = new XmlTextWriter(xmlfilepath, null))
            {
                myXmlWriter.Formatting = Formatting.Indented;
                myXmlWriter.Indentation = 4;
                myXmlWriter.WriteStartElement("issues");
                int i = 0;
                for (i = 1; i <= 5; i++)
                {
                myXmlWriter.WriteStartElement("job");// see next line
                myXmlWriter.WriteAttributeString("dt", "");
                myXmlWriter.WriteAttributeString("mid", "");
                myXmlWriter.WriteAttributeString("shipment", "");
                myXmlWriter.WriteAttributeString("name", "Ashish + i");
                myXmlWriter.WriteElementString("sername", "Sharma + i");
                }
                myXmlWriter.WriteEndElement();
                myXmlWriter.Flush();
                myXmlWriter.Close();
            }
        }

Output XML will be

<?xml version="1.0"?>
<issues>
<job name="ashish1" shipment="" mid="" dt="">
 <sername>sharma1</sername> 
</job>
<job name="ashish2" shipment="" mid="" dt="">
 <sername>sharma2</sername> 
</job>

Merge PDF pages into One PDF Document in Csharp(Pdf Sharp dll)

In my previous post i have explain how to splite pdf documents

Some times we have requirement to Merge PDF document into one PDF Documents.
In this Article i am explaining how to merge pdf document into one.
For this i used pdfSharp dll which is free available into internet.
i am describing this example step by step.

Step 1(Create new Project)
Open Visual Studio
Go to File–>New–>Project

Go to Window Form Application and Give the “Mergepdfdoc” name to the project.

a new Form is showing right Click on Window Form and select View Code.
Step 2
put your inputpdf1.pdf,inputpdf2.pdf……….(you can choose another name) into debug folder of your project.
output file will also created in debug folder of your project.
Step 3
dowonload PdfSharp.dll from internet.
now add the reference of this dll to your project.
Right click on your solution Explorer–> Add Reference –>Browse(browse the downloaded dll path)–> ok
now add the button control on your page.
Drag and Drop the Button Control from the Toolbar and name it “btnmergepdf”.
double click on button and generate the OnClick Event.
step 4>
Create a function for Merging the pdf documents

        private static void MergeMultiplePDFIntoSinglePDFDoc(string outputpdfFilePath, string[] pdfFilescoll)
        {
            //create a new pdf output document
            PdfDocument outputPDFDocument = new PdfDocument();
            //loop for reading input pdf files 
            foreach (string pdfFile in pdfFilescoll)
            {
                PdfDocument inputPDFDocument = PdfReader.Open(pdfFile, PdfDocumentOpenMode.Import);
                outputPDFDocument.Version = inputPDFDocument.Version;
                //loop for reading all pages of input files
                foreach (PdfPage page in inputPDFDocument.Pages)
                {
                    // adding the input pages into output pdf documents
                    outputPDFDocument.AddPage(page);
                }
            }
             // At last save the output document
            outputPDFDocument.Save(outputpdfFilePath);
        }

Step 5
call the MergeMultiplePDFIntoSinglePDFDoc function into onClick event of btnmergepdf

        private void btnmergepdf_Click(object sender, EventArgs e)
        {
         string outputpdffilename = "mynewpdf.pdf";
         string[] Collofinputddffiles = {"inputpdf1.pdf","inputpdf2.pdf","inputpdf3.pdf"};
         MergeMultiplePDFIntoSinglePDFDoc(outputpdffilename ,Collofinputddffiles );
        }

Splite PDF document using Csharp(pdf Sharp dll)

Some times we have requirement to Splite PDF document into several PDF Documents.
In this Article i am explaining how to Splite Large pdf document.
For this i used pdfSharp dll which is free available into internet.
i am describing this example step by step.

Step 1(Create new Project)
Open Visual Studio
Go to File–>New–>Project

Go to Window Form Application and Give the “SplitPdfDoc” name to the project.

Drag and Drop the Button Control from the Toolbar and name it “btnsplitepdf”.
double click on button and generate the OnClick Event.

Step 3
put your input.pdf(you can choose another name) into debug folder of your project.
output file will also created in debug folder of your project.

Go to CodeBehind and copy paste the following code within button Onclick Event.

        private void btnsplitepdfdoc_Click(object sender, EventArgs e)
        {
            // input pdf file name
            string inputfile = "input.pdf";
            // read the pdf document
            PdfDocument inputPDFDocument = PdfReader.Open(inputfile, PdfDocumentOpenMode.Import);
           // get pdf file name without .pdf extension
            string filenamewoext = Path.GetFileNameWithoutExtension(inputfile);
            // loop for spliting the pdf document on the bases of pageIndex
            for (int pageIndex = 0; pageIndex < inputPDFDocument.PageCount; pageIndex++)
            {
                // create new output pdf document
                PdfDocument outpdfdoc = new PdfDocument();
                outpdfdoc.Version = inputPDFDocument.Version;
                outpdfdoc.Info.Title =
                  String.Format("Page {0} of {1}", pageIndex + 1, inputPDFDocument.Info.Title);
                outpdfdoc.Info.Creator = inputPDFDocument.Info.Creator;
 
                // Add the page
                outpdfdoc.AddPage(inputPDFDocument.Pages[pageIndex]);
                // save the new output page
                outpdfdoc.Save(String.Format("{0}-{1}.pdf", filenamewoext, pageIndex + 1));

        }
    }

Merge GridView Header

protected void grvMergeHeader_RowCreated
(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
GridView HeaderGrid = (GridView)sender;
GridViewRow HeaderGridRow =
new GridViewRow(0, 0, DataControlRowType.Header,
DataControlRowState.Insert);
TableCell HeaderCell = new TableCell();
HeaderCell.Text = “Department”;
HeaderCell.ColumnSpan = 2;
HeaderGridRow.Cells.Add(HeaderCell);

HeaderCell = new TableCell();
HeaderCell.Text = “Employee”;
HeaderCell.ColumnSpan = 2;
HeaderGridRow.Cells.Add(HeaderCell);

grvMergeHeader.Controls[0].Controls.AddAt
(0, HeaderGridRow);

}
}
}

Read Attributes and Elements of XML Documents

    public void ReadAEOfXml()
    {

        XmlTextReader xtr = new XmlTextReader("D:/mapping1.xml");
        while(xtr.Read())
        {
