Hi, I have implemented the ICallbackEventhander interface and successfully updating the page asynchroniously on keydown on a textbox. I tried to implement the same with the click event of the asp.net button or imagebutton's click event but RaiseCallback is invoked and then the GetCallbackResult() is called but the last client side javascript function is not called that infact updates the page, hence the page not updates. Also once the page is partially updated on keydown of textbox, after that no server side event is triggers. What could be the issue. Any code or reference url for the solution of this problem will be much appreciated. Thanks, Safvi

Hi, I have implemented ICallbackEventHandler interface on a page and calling it in different context with different controls. Its working okay on keydown of a text box, click of an html button control and mouseover of a button control. But i need to use it with imagebutton or button control at click event. On click event the RaiseCallbackEvent function is called, then the GetCallbackResult(), but after that the GetCallbackResult() does not call the java script function that updates the page with the results retreived from GetCallbackResult(). This is only happning with click event of the ASP.net button or image button control and here also every thing is being invoking except the last javascript funciton that updates the page. Apparently there seem no problem in my code. it seems some thing special is required to be done for click event of the asp.net because same is done with the html button control. Second issue is that once the after the icallback, no server side event is fired e.g row_command of a gridview control. simply gv is cleared. Please help me. Most of the work is done, only minor issue is frustating me. Thanks, Safvi

Hello, My application is in Asp.net1.1 hence the third party ABCpdf can be used in this project. Hence i created a webservice in Asp.net2.0. Upon test run, its working okay and creating the PDF document from a url and saving in one of the directory of my orignal application written in ASP.net1.1. I created the proxy class using Wsdl.exe of vs2005 and added the class in the ASp.net1.1 application.Build is okay. no error. But this class in not refereced in the project. Hence i cannot invoke the method to save the webpage as PDF. How to reference the proxy class. Its object is not being created and the project is not recognizing. The rest of the ASp.net1.1 project is in VB.net but this proxy class in in C#. What should i do.Every thing is working okay i just need to invoke the webservice from ASP.net1.1 project. Plz help. Thanks, Ali

Hello, I have to convert an .aspx page to PDF. I tried to use the AbcPDF.net 7.1 but its dll were failed to be referenced in a Visual studio 2003 with .Net1.1, project. May be because it does not support dotnet1.1. Can anybody tell me which version is compatible with ASP.Net 1.1. Or there any other alternate 3rd party to convert an asp.net 1.1 page to PDF. Will be very thankful for a propmt reply. Thanks, Safvi

hello, On page load event i am generating a report in an aspx file and then capturing the html and saving it as html file to be sent as emil attachemt. This has to be done multiple times for different users. I am overriding the render method of the page to get the html. It works okay for the first time but i need to create the report multiple time. When the below code is called for second time on page load event to capture the newly created report, it gives the error '"A page can have only one server-side Form tag"'. Following the code. Dim sb As New System.Text.StringBuilder Dim sw As New System.IO.StringWriter(sb) Dim hWriter As New HtmlTextWriter(sw) MyBase.Render(hWriter) ' *** store to a string Dim PageResult As String = sb.ToString() ' *** Write it back to the server writer.Write(PageResult) str = PageResult i get error on MyBase.Render(hWriter). Remember its working okay for the first. So how can i get the html of the page multiple times???? Thanks, Safvi

Hi, I am importing data to sqlserver2005 from a csv file. But the folder where i upload the file before import is unaccessible even though i have given full rights to everyone accessing this folder or even the root folder of the application for testing purposes. I am getting error 'invalid File' (though the file is valid csv) on my system where Norton and Kaspersky are installed but when i tryed to import data from same file using other system it did not give error and file was uploaded successfully and then imported to database. I have restarted the deployment server. Should i restart iis admin servies or what should i do. I have given full rights on the folder where i m uploading the file before importing it to database. Thanks, Safvi

Dear All, In download data module of my application(with asp.net2.0/sqlserver2005)one of the function is returning a datareader object having 7 hundererd thousands plus record. It returns the datareader without an exception but when i am iterating through the datareader to take its values to a string bulider type varible to write a csv file, it throws an 'System.OutOfMemoryException' due to huge records. I can not filter the record as it is required to write a csv file of the whole data. how can i avoide this error and improve the efficency of the system so that it takes less resources. The compilation debug is set to false. Also when there a few hundered thousand records the download is working ok. Thanks in advance for the help form any esteemed member. Thanks, Safvi

Thanks for your suggestion David, It really impreoved the efficiency of my download module by using datareader inspite of datatable and now i was able to write more then 2 million records to a csv file. But still this exception is thron when the no of records exceeds like in my case 7 Millios. What else should i do.? Thanks again for your valuable suggestion that solved my 50% problem. Safvi
