C#

for (int i=0;i<dataGridView1.RowCount-1;i++)
        {
            // Test if the first column of the current row equals
            // the value in the text box
           
            if (dataGridView1.Rows[i].Cells[2].Value.ToString().Trim() == toolStripTextBox1.Text)
            {
                // we have a match
                dataGridView1.Rows[i].Selected = true;
            }
            else
            {
                dataGridView1.Rows[i].Selected  = false;
            }
        }

that code no this to work for secund  
column of the datagridview 

so I got the code from the msdn website:
https://msdn.microso...udiostream.aspx , just to check and see if everything is working. 
and since i do not have the wav file specified in the original code i downloaded my own wav file and inserted the address of it.
the program works but it prints out something completely different words that are not even in the wav file audio.


here is the code

              new SpeechRecognitionEngine(new CultureInfo("en-US")))
            {

                // Create and load a grammar.
                Grammar dictation = new DictationGrammar();
                dictation.Name = "Dictation Grammar";

                recognizer.LoadGrammar(dictation);

               //Configure the input to the recognizer.

                recognizer.SetInputToWaveStream(

Doc theDoc = new Doc();

       theDoc.Rendering.DotsPerInchY = 400;


       int n = theDoc.PageCount;

       for (int i = 1; i <= 1; i++)
       {

           theDoc.PageNumber = i;

           theDoc.Rect.String = theDoc.CropBox.String;

           theDoc.Rendering.SaveAppend = (i != 1);

<?xml version="1.0" encoding="utf-8"?>
<MAIN>
  <Items>
    <Name>name1</Name>
    <Data>data1</Data>
    <Category>category1</Category>
  </Items>
  <Items>
    <Name>name2</Name>
    <Data>data2</Data>
    <Category>category2</Category>

  <Items>
    <Name>name3</Name>
    <Data>data3</Data>
    <Category>category2</Category>//same category as above

  ...
  <Items>
    <Name>name20</Name>
    <Data>data20</Data>
    <Category>category16</Category>
  </Items>
</MAIN>

Now I need to create an List with category1, category2, ... upto what the categories is there on Category Node, need to create a separate Lists of each category to store the item name and every item list will have data of the item so I can retrieve them for my use.

From above sample xml I need the same category items in a single List

Items and Category count is fully dynamic. How to do this dynamically?
