string arr = System.IO.File.ReadAllLines(txtfile path); foreach (var a in arr) { MesssageBox.Show(a); } foreach will show your all line. Put all line where you want to put. (Ravi D. Sangtani)

Hi, I assume you have 20 columns separated with pipe "|" . Just give the textbox names as T0 T1 T2 T3 T4 T5 and so on. string FilePath=HttpContext.Current.Server.MapPath(PATH_WHERE_FILE_RESIDES); StreamReader Streader = new StreamReader(FilePath); string FileData = Streader.ReadToEnd(); Streader.Close(); and follow below loop. string[] TextBoxValues = FileData .Split('|'); for(int i=0;i { ( this.Controls["T" +i.ToString()] as TextBox).Text = TextBoxValues[i]; } Hope it helps. If not please let me know. Cheerss... :) Thanks.

Hi, First you map the path of the file using string FilePath=HttpContext.Current.Server.MapPath(PATH_WHERE_FILE_RESIDES); then StreamReader Streader = new StreamReader(FilePath); string FileData = Streader.ReadToEnd(); Streader.Close(); now the FileData Variable will hold all the data from the file, you can perform the string operations and show it to the destination textboxes. Please let me know if need any assistance. Hope it helps. Thanks.

Hi, Dear its not proper method to save the file data in table because when you retrieve data the process becomes slow as data increases. Though you want to save it in table just keep the columns type NVARCHAR(MAX) and put whole content of file into table just using procedure. One more method is just put the file name in the column and save the file in a folder let say Files and retrieve when needed using StreamReader. If you have any query please let me know. Sorry for the late reply. Thanks. Cheers...
