Hi I want to display only the first 200 chars of text stored in the DB as a text field.  How do I do this so that it is cut off after a word and not in the middle of a word??  Also, I am displaying the text in a GridView.

assume you have the text insome variable after your query succeeds:
string longTxtFromDB = "extremely long text more than 200 characters ... .. . . ..  ..";
int i = longTxtFromDB.IndexOf(' ', 200); //find the index of first occurrence of space from the 200th characters
string cutOffString = longTxtFromDB.Substring(0,i);//substring the original txt

if you want that the total of characters after the substring will be always less or equal to 200 then you need something a bit different:

string longTxtFromDB = "extremely long text more than 200 characters ... .. . . ..  ..";
var st = new string(longTxtFromDB.Reverse().ToArray());
                int i = st.IndexOf(' ', longTxtFromDB.Length - 20);
               string cutOffString = longTxtFromDB.Substring(0, longTxtFromDB.Length-i);

Open in new window


btw, i used 20 just for testing, you should first check if the string length is more than 200:

string longTxtFromDB = "extremely long text more than 200 characters ... .. . . ..  ..";
if(longTxtFromDB.Length> 20){
var st = new string(longTxtFromDB.Reverse().ToArray());
                int i = st.IndexOf(' ', longTxtFromDB.Length - 20);
               string cutOffString = longTxtFromDB.Substring(0, longTxtFromDB.Length-i);
}

Thanks - I didn't use the T-SQL solution but didn't know about SUBSTRING so thank you Akila :-)
