Re: Validation and Data storing in one step Kornfeld Eliyahu Peter28-Jan-14 20:17 Kornfeld Eliyahu Peter 28-Jan-14 20:17  I can offer you two ways... 1 - Put the validation into the property setter (simple). 2 - Write (or find) an attribute that gets the regex as parameter and validates the property decorated with (much powerful). I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V) Re: Validation and Data storing in one step nitin_ion28-Jan-14 20:27 nitin_ion 28-Jan-14 20:27  i am also trying the 2 approach and for that i have to write a custom attribute. Re: Validation and Data storing in one step Kornfeld Eliyahu Peter28-Jan-14 20:31 Kornfeld Eliyahu Peter 28-Jan-14 20:31  Great - when you ready made it into an article to share with all!!!

(V) Re: Validation and Data storing in one step nitin_ion28-Jan-14 20:38 nitin_ion 28-Jan-14 20:38  This is a win form application i have created a class public class ValidateProperty : Attribute { string _pattern; bool _mandatory; public ValidateProperty(string Pattern, bool Mandatory = false) { _pattern = Pattern; _mandatory = Mandatory; } public override bool Match(object obj) { Match m = Regex.Match((string)obj, _pattern); if (_mandatory == true) { if (string.IsNullOrWhiteSpace(m.Value)) return false; else { return true; } } else return true; } } and then applied on property [ValidateProperty(@"[a-zA-Z@$^�-9\s\S]{70}",true)] public string ClientName { get; set; } but it is not validating when i put a string with less than 70 char. even in debug mode code is not going to match function Re: Validation and Data storing in one step Kornfeld Eliyahu Peter28-Jan-14 20:41 Kornfeld Eliyahu Peter 28-Jan-14 20:41  {70} doesn't mean exactly 70, but up to 70!!! The correct format of {} is {m,n} where m is from and n is to... When you use only one number it interpreted as {0,n}. For exactly 70 characters try {70,70}!!!

(V) Re: Validation and Data storing in one step nitin_ion28-Jan-14 20:43 nitin_ion 28-Jan-14 20:43  yeah that's fine but issue is that it is not fired even if i pass null or less than 70 char less than 70 so it should return false or should not accept value in that property. but currently it is not happenin Re: Validation and Data storing in one step Kornfeld Eliyahu Peter28-Jan-14 20:45 Kornfeld Eliyahu Peter 28-Jan-14 20:45  You attribute's Match method got hit?

(V) Re: Validation and Data storing in one step nitin_ion28-Jan-14 20:46 nitin_ion 28-Jan-14 20:46  No it does not get hit. ClientName="dd"; Re: Validation and Data storing in one step Kornfeld Eliyahu Peter28-Jan-14 20:50 Kornfeld Eliyahu Peter 28-Jan-14 20:50  Go and read this: http://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.validationattribute(v=vs.110).aspx[^] It may also bee of interest: http://msdn.microsoft.com/en-us/library/ff649907.aspx[^] http://msdn.microsoft.com/en-us/library/ee707335(v=vs.91).aspx[^] And also read some regex - yours is a mess...

(V) Re: Validation and Data storing in one step nitin_ion28-Jan-14 23:18 nitin_ion 28-Jan-14 23:18  this is good thanks but data i will have is something like this RA01XYZ 201401231445012345611012345678998765432101234DESTINATIONNAMESIZEIS70 RA is one field 01 is one field XYZ is on and so on so i will have to extract and then validate any suggestions Re: Validation and Data storing in one step Kornfeld Eliyahu Peter28-Jan-14 23:21 Kornfeld Eliyahu Peter 28-Jan-14 23:21  With regex you can validate without breaking it apart...

(V) Re: Validation and Data storing in one step nitin_ion28-Jan-14 23:22 nitin_ion 28-Jan-14 23:22  yeah but then we will have to validate through regex and store it in property separately i guess this is what they call catch 22 Re: Validation and Data storing in one step Kornfeld Eliyahu Peter28-Jan-14 23:31 Kornfeld Eliyahu Peter 28-Jan-14 23:31  I think not. You should pass the regex as a property to your new attribute... I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V) Re: Validation and Data storing in one step nitin_ion28-Jan-14 23:37 nitin_ion 28-Jan-14 23:37  that's what i am doing but see i need to first extract validate store [RegexValidator(@"[a-zA-Z@$^�-9\s\S]{2}", ErrorMessage = "ok")] public string RecordType { get; set; } [RegexValidator(@"[a-zA-Z@$^�-9\s\S]{2}",ErrorMessage="ok1")] public string VersionNumber { get; set; } [StringLengthValidator(1, 50, MessageTemplate = "Last Name must be between 1 and 70 characters")] public string ClientName { get; set; } ----------------- string Line="RA01XYZ 201401231445012345611012345678998765432101234DESTINATIONNAMESIZEIS70 SENDINGENTITYIDENTIFIER SENDERNAMESIZE70 "; p.RecordType = Line; p.VersionNumber = Line; Now issue is that it will always start from 1 character it will not increment RecordType will start from 1 to 2 so VersionNumber should start from 3 to 4 and ClientName from 5 to 50 i guess i'll try mentioning this using StringLength validator but then datatype validation will be a case Re: Validation and Data storing in one step Kornfeld Eliyahu Peter29-Jan-14 0:16 Kornfeld Eliyahu Peter 29-Jan-14 0:16  I see. For that you have to write an other class/method to split the string into fields...

(V) Re: Validation and Data storing in one step nitin_ion29-Jan-14 21:09 nitin_ion 29-Jan-14 21:09  thanks now i guess i cant do evs in one step so i am extracting first using substring and then validating and storing using attributes [EL] [RegexValidator(@"[a-zA-Z@$^�-9\S]{2}", MessageTemplate = "RecordType Validation failed")] Re: Validation and Data storing in one step Matt T Heffron29-Jan-14 10:24 Matt T Heffron 29-Jan-14 10:24  Just attaching a custom attribute to the property doesn't automatically cause some validation. You must have something that looks for an "appropriate" attribute, using Reflection, typically, and causes the actual validation.

(V) Re: Validation and Data storing in one step Matt T Heffron30-Jan-14 6:38 Matt T Heffron 30-Jan-14 6:38  I see... However, the OP didn't derive from ValidationAttribute, they derived directly from Attribute: C# public class ValidateProperty : Attribute and that's NOT going to work.

(V) Highlight Text in html document Sumit Rastogi SRA27-Jan-14 20:27 Sumit Rastogi SRA 27-Jan-14 20:27  I have one html document . I want to highlight text in html document but which text I want to highlight that is repeated text in html document . But I want to highlight only exact text according to my requirement then how can I determine the exact text which I want to highlight . Manually, I know that this text should have to highlight but how programmatically determine exact text to highlight between duplicates. Please some one can help to me. My exact scenario is giving below- I want explain my scenario I have some pdf and converting in epub file.After converting some text font name or font style missing then I have to compare with pdf and epub and highlight the exact text which font is missing.But because of duplicates I am not able to determine the text for highlight. modified 28-Jan-14 5:01am. Re: Highlight Text in html document Richard MacCutchan27-Jan-14 22:18 Richard MacCutchan 27-Jan-14 22:18  If you don't know which text to highlight then how do you expect anyone else to know?

Re: Highlight Text in html document OriginalGriff27-Jan-14 22:27 OriginalGriff 27-Jan-14 22:27  I wish I could, but my brain melted trying to work out exactly who does know which text you want to highlight... This is not a good question - we cannot work out from that little what you are trying to do. Remember that we can't see your screen, access your HDD, or read your mind.
