You have a problem with declaring the array:

Datarow Mydatarow [][] = Datarow[5][5] ;

should be 

Datarow[][] Mydatarow = new Datarow[5][];

So:

Mydatarow[Index][i].ItemArray[3]= "S";//should work fine

  • @Masoud are you facing any exception? if so what is it? – Jalal Said Jul 30 '11 at 18:09
  • No. it word good . but value don't change – Masoud Abasian Jul 30 '11 at 18:19
  • @Masoud the value doesn't change where? in a gird view? if you insert a break point at the line `Mydatarow[Index][i].ItemArray[3]= "S"` and run the project "F5", now when the function that execute that line triggers, the break point will stop at that line, now you should see the previous value of the `ItemArray` at index 3, now press f10 so only this line will be evaluated, you now will see that the value is actually changed.. – Jalal Said Jul 30 '11 at 18:32
