I have a simple form with some dropdownlist and text boxes (server controls). When I click the save button, it will perform a simple update in a table. The weird thing is that it takes about 3 to 4 seconds to post back. Saving the information in database takes less than a second. I set up a trace and the idle is between Begin Raise PostBackEvent and End RaisePostBackEvent as is shown below: Trace Information Category Message From First(s) From Last(s) aspx.page Begin Init aspx.page End Init 0.000383 0.000383 aspx.page Begin LoadViewState 0.000410 0.000027 aspx.page End LoadViewState 0.000911 0.000501 aspx.page Begin ProcessPostData 0.000933 0.000023 aspx.page End ProcessPostData 0.001130 0.000197 aspx.page Begin ProcessPostData Second Try 0.001213 0.000083 aspx.page End ProcessPostData Second Try 0.001237 0.000024 aspx.page Begin Raise ChangedEvents 0.001255 0.000018 aspx.page End Raise ChangedEvents 0.001280 0.000025 <b>aspx.page Begin Raise PostBackEvent 0.001298 0.000018</b> <b>aspx.page End Raise PostBackEvent 3.517342 3.516044</b> aspx.page Begin PreRender 3.517393 0.000051 aspx.page End PreRender 3.517547 0.000154 aspx.page Begin SaveViewState 3.519734 0.002188 aspx.page End SaveViewState 3.519846 0.000111 aspx.page Begin Render 3.519867 0.000021 aspx.page End Render 3.522489 0.002622 Any help on how to solve or improve the performance it is really appreciated.

If saving the information takes less than a second, what do you do other than that? --- b { font-weight: normal; } Re: Mysterious behaviour [modified] lnu0128-Nov-06 9:44 lnu01 28-Nov-06 9:44  That's the weird thing.

Do you have any other event handlers? Page_PreInit? Page_Load? Page_PreRender? --- b { font-weight: normal; } Re: Mysterious behaviour lnu0129-Nov-06 3:20 lnu01 29-Nov-06 3:20  I have some overridable functions but I check them if it is a postback before performing anything. So from that side I know there is not extra trip to the server it is just what happend before the postback event, where the 3 to 4 seconds occurs. If I found what was the cause, I'll definetly let you know. Thanks for your help anyway. Report Service Expression Evaluation. Christopher Stratmann28-Nov-06 8:43 Christopher Stratmann 28-Nov-06 8:43  Is there any way in C# to evaluation and Expression created in reporting services? Example evaluating the expression =Globals!ReportName + ".rdl" which would return MySample.rdl. I know this is a very simple example and I would like to evaluate very complex expressions. It looks like the expression is in VB.NET with a few addins like Globals!ReportName, Globals!ExecutionTime, etc. Therefore I could create a sample VB.NET project and make my C# code compile a VB.NET executable with the expression inside VB.NET project with the "addins" replaced with their text representation, but this would be a lot of work. Thats what I am trying to avoid. Has anyone come up with a solution? Chris Re: Report Service Expression Evaluation. Christopher Stratmann7-Dec-06 2:34 Christopher Stratmann 7-Dec-06 2:34  Just incase if anyone is wondering I had to create a class that would compile the VB.NET assembly with the expression code to get back a value.

Goalie3528-Nov-06 5:39 Goalie35 28-Nov-06 5:39  I have to run a crystal report within a specified date range and display this date range in the header of the report. So, for example, I may be grabbing all data between 10/1/2006 & 10/31/2006. I would then need to place on the header of the report "Period: 10/1/2006 - 10/31/2006". These two dates would be specified within an asp.net textbox before the report is generated. How can I pass these 2 dates to display on the report?

For example, in visual studio, you can debug your program on your machine with no problem however when you're ready to upload it to a server, you need to switch your "Solution Configuration" dropdown from "Debug" to "Release", then select "Build" --> "Rebuild Solution". This will compile your project (your vb, c#, j#, or whatever your coding in) into a single DLL file, which can be located in your "Bin" folder. Upload your projects' DLL file to the "Bin" folder on the server and then upload your aspx file to its propper folder. Also, since we're discussing troubleshooting options, ensure that the server you're uploading to is not only asp.net compatible but is also compatible with the version of asp.net you're using (i.e. a server with only the 1.1 .NET Framework will not run a project created in the 2.0 framework). -Goalie35 Re: how to use asp.net page on web trannguyen8628-Nov-06 8:26 trannguyen86 28-Nov-06 8:26  thank for help but it still does not work, i complile it , check version, (i use .net 2003) , correct web.config file, in my conputer it run very well, but on web it does not work! ___________ tran nguyen Re: how to use asp.net page on web Goalie3528-Nov-06 8:38 Goalie35 28-Nov-06 8:38  What's the actual error you're receiving?

Getting column data from GridView on page using MasterPage marconi Flangepants28-Nov-06 4:03 marconi Flangepants 28-Nov-06 4:03  Hi, Im having problems getting the value from a column in my GridView. I Have tried all of the following methods and a few others but none return the value and most just give Object not found errors. <code>protected void GridView1_SelectedIndexChanging(object sender, GridViewSelectEventArgs e) {//test message ShowMessageBox("CHANGING"); //Label temp=null; //temp.Text = (GridView1.FindControl(Label1.Text)).ToString(); //Label11.Text = GridView1.FindControl(Label1.Text).ToString(); //Label11.Text = GridView1.SelectedDataKey.Value.ToString(); //Label11.Text = GridView1.UniqueID.ToString(); //Label11.Text = GridView1.SelectedDataKey.Values.ToString(); //Label11.Text=GridView1.DataKeys.ToString(); //Label11.Text=GridView1.SelectedRow.Cells[0].Text; }</code> Any help would be great. Im wondering if the problem is anything to do with the fact im using a masterpage for the template of the actual page im working on????
