Every gridview is binded by dataview. And when I'm using filter by sending filter criteria using textbox, it is possible to send any kind of string to filter the dataview. Now problem is when I send string like 1) *text, it works fine 2) text*, it works fine 3) te*xt, it fails why this is so? Can someone please help me in this regard Solution on this will be appreciated Regards Balasaheb Kahat Balasaheb Software Developer Platform: Asp.net,vb.net Re: how to use Filter on Dataview string like te*xt% Sylvester george19-Feb-07 19:52 Sylvester george 19-Feb-07 19:52  WILDCARD CHARACTERS Both the * and % can be used interchangeably for wildcard characters in a LIKE comparison. If the string in a LIKE clause contains a * or %, those characters should be escaped in brackets ([]). If a bracket is in the clause, the bracket characters should be escaped in brackets (for example [[] or []]). A wildcard is allowed at the start and end of a pattern, or at the end of a pattern, or at the start of a pattern. For example: "ItemName LIKE '*product*'" "ItemName LIKE '*product'" "ItemName LIKE 'product*'" Wildcard characters are not allowed in the middle of a string. For example, 'te*xt' is not allowed. for more info ============= http://msdn2.microsoft.com/en-us/library/system.data.datacolumn.expression.aspx[^] Regards, Sylvester G Senior Software Engineer Xoriant Solutions sylvester_g_m@yahoo.com Re: how to use Filter on Dataview string like te*xt% BalasahebK19-Feb-07 20:31 BalasahebK 19-Feb-07 20:31  ok then how to solve above problem using dataview because user can send string like te*xt, is there any way?

Explaination:- RowFilter = "Name Like 'Sar[*]avanan'" Suppose Name contains like "Sareeavan", the above doesn't return "Sareeavan" as result, but returns blank I have a column named "ref" which contains records like 0007k, 0017,0127, I like find out records such as starting with 0*7 search criteria (This should min return 0007k, but wont). As per logic 0*7 should return all above values as result. RowFilter doesn't work on such criteria, do u have any solution on such criteria?

We can not do any pattern like 'te*xt' . If you want escape the character * from users input. we need to use delimeter [ and ] to remove compilation errors.

What I was doing earlier Retreiving data from database and keep it in cache[20 mins] For every postback on same page, dataset is fill with this cache data. Then this ds is converted into dataview in order to filter the record. Postback happen when 1) on button click Filter, 2) ShowAll button Click 3) Paging 4) Sorting Regards Balasaheb Software Developer Platform: Asp.net,vb.net Database: SQL Server 2000 Re: how to use Filter on Dataview string like te*xt% Sylvester george20-Feb-07 2:12 Sylvester george 20-Feb-07 2:12  Yes. You should handle this kind of pattern in Database query or Do it manually. You can not get advantage from RowFilter for this sort of patterns Regards, Sylvester G Senior Software Engineer Xoriant Solutions sylvester_g_m@yahoo.com XML -2033 Bytes Amit Kumar G19-Feb-07 11:09 Amit Kumar G 19-Feb-07 11:09  I am working on VS 2005 and SQL 2005.

Amit button not causing postback on click??? bradz1519-Feb-07 10:55 bradz15 19-Feb-07 10:55  I'm working on this app and had all my buttons and things on this page working. I have to add some more things, so I elect to use a tabstrip (a componentart tabstrip). So now my original page is on a multipage. Everything looks good and seems right but when the buttons are clicked the page is not posting back?? Anyone know what gives? Re: button not causing postback on click??? Vsree19-Feb-07 17:49 Vsree 19-Feb-07 17:49  hi Check if you have any validators in any of the pages in your multipage firing validation,but you may not have given the error message to display. Or,check the InitialiseComponent() method for the event handlers because i faced the similar problem and in my application,i had some javascripts and after adding it, the event handlers weren't there in InitialiseComponent() method ... Check for it too... Also do anyone know what have caused the evenhandlers in InitialiseComponent() method to vanish off,when i added Javascript code in my application? ~VSree Re: button not causing postback on click??? bradz1520-Feb-07 5:44 bradz15 20-Feb-07 5:44  Yea, I disabled them to see.

Sandeep Akhare19-Feb-07 19:05 Sandeep Akhare 19-Feb-07 19:05  Hi I think if you are using ASP.net 1.1 and if you have changed the name of the button then it maight had happened check the button event name and Id of button both are same and Event handler declaration should match it <l>Thanks and Regards Sandeep Re: button not causing postback on click??? bradz1520-Feb-07 5:44 bradz15 20-Feb-07 5:44  I'm using 2.0 Re: button not causing postback on click??? sathesh pandian19-Feb-07 22:39 sathesh pandian 19-Feb-07 22:39  i think you have to enable the autopostback=true Sathesh Pandian Re: button not causing postback on click??? bradz1520-Feb-07 5:44 bradz15 20-Feb-07 5:44  Not the problem.

How ? <l>Thanks and Regards Sandeep Webservice namespace itemplate19-Feb-07 9:52 itemplate 19-Feb-07 9:52  Hi all, If I create a new hello-world webservice or similar declared like this: [System.Xml.Serialization.XmlRootAttribute(Namespace = "http://HelloTest/2007/01", IsNullable = false, ElementName = "HelloResponse")] And serializes the response - in the service - theres a nice namespace on the root node like this: <HelloResponse xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns=http://HelloTest/2007/01> This is also present when invoked from a browser. But if I add a webservice reference in Visual Studio and call this method, the "xmlns" attribute is not showing in the Xml! Where? Why??? It is extremely important that this namespace stays on the root node. What am I missing here? If I extend the response to include some other nodes mapped from classes with own namespace declarations those namespace gets shown - on those nodes that is. Not on the root node. And I need it on the root node Its really drivíng me nuts - plz clarify... -- Werner Webservice schemalocation [modified] itemplate19-Feb-07 9:51 itemplate 19-Feb-07 9:51  Hi all, From participating in various forums I understand that it is impossible to get a "xsi:schemaLocation" in a Webservice response created using C# and VS2005 - unless the response is hardcoded implementing the IXmlSerializable interface..See http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1236565&SiteID=1 for reference. In general all I want is that attribute to appear on the root node. But can it really be that I have to implement the above interface just to attach an attribute to a webservice response? Im using VS2005 and .NET 2 if that matters...

Smith19-Feb-07 8:43 Marcus J. Smith 19-Feb-07 8:43  Session variables allow you to store information between post backs. The web is stateless, meaning that it doesnt know what it sent you what you are doing or anything between server hits, so to maintain this you can use session variables/cookies/etc... The session variables can be set simply by coding Session("VariableName") = Value and then can be retrieved by coding Value = Session("VariableName"). The session is maintained by a SessionID that is created at the first request and is stored as a session cookie in the user's browser in most cases. Cleako Re: how to session variable Neeraj Arora19-Feb-07 17:25 Neeraj Arora 19-Feb-07 17:25  As cleako has described session mentain user information. it can be stored at client side or server side both. At client side, it is stored in cookies and if cookies are disabled then automatically it goes to server. You can keep your session data in database also which is most effective. I hope, this information will help you a bit. Images Amit Kumar G19-Feb-07 7:40 Amit Kumar G 19-Feb-07 7:40  Hi Guys I am sorry for posting this query here. But no wonder, i don;t find any other site as we have codeproject.com. I love you guys for wonderful work. I have one small query but it is very critical for me. I need to read text from images(gif, bmp, tif etc..). No coding is required, i am looking for some tool where i can open the image and then copy the text in clipboard. That's it. I tried couple of free software e.g. snagit, mspaint.net, nitro etc... But ....SO please help me and suggest some good free tools to done this job. Otherwise, i need to type all this and very soon i will be called data entry operator..........please please help me Amit Re: Images Guffa19-Feb-07 8:33 Guffa 19-Feb-07 8:33  Images doesn't contain text, it contains the graphic representation of characters. Therefore there is no easy way to just copy the text. What you need is software that can recognise the characters and make text from them. This is called optical character recognition, so what you should look for is OCR software. --- single minded; short sighted; long gone;
