By default it wont take '. U need to replace it by ' ' while storing into database but dont worry it will store the ' only. Use the following code: Say u want customer name should accept '. like peter's.So the time of saving use the following convertion in your pagebehind class(.aspx). txtCustomerName.Text.Replace(" ' ", " ' ' ").Trim()

Thnx Rakrus for your reply. But still it's not working properly. Here i'm giving my code string name=Server.HtmlEncode(txtName.Text); string strsql="Update Rough Set Name='"+name.ToString()+"' Where Active=1";

Rakrus · Answer

string strTxtVal=Server.HtmlEncode(TextBox1.Text); use the above encoded value to insert into database. While retrieving the save value from database you need to decode it and set it to textbox. TextBox1.Text=Server.HtmlDecode(encoded textbox value (i.e value from database)) I think you got it.
