What can b the reason. please help Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

The control is to be placed directly on the form itself, should not use any container controls like panel chandra Re: Windows .net(C#) PandemoniumPasha19-Feb-07 21:00 PandemoniumPasha 19-Feb-07 21:00  as far as i understand u're question you want to add a control to the form and make it visible while scrolling, right? in such a case, just add the control to the form either in design time or at runtime. set the autoscroll property of the form to true, and the visible property of the control to true (true by default). if add during runtime, you need to specify the locatin where the control is to be placed and then you add the control to the container of the form e.g. this.Controls.Add(this.button1); in case of C# where 'button1' is the control u added. barcode on crystal report Laxmikant Lad19-Feb-07 17:49 Laxmikant Lad 19-Feb-07 17:49  tal reporthi frineds i want to print barcode images on Crystal Report barcode images are stored in database as varbinary datatype i want fetch these images and show it on crystal report how can i do this ? thank you how to use Filter on Dataview string like te*xt% BalasahebK19-Feb-07 17:30 BalasahebK 19-Feb-07 17:30  Hello Everybody, Can someone help in finding solution for dataview filter I know how to use dataview filter and I had been using dataview for my application for biding 5 gridview. 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.

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.

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
