• Re: session variable doesn't load on first button click

  It is being declared globally like so: Dim strSQLFilter As String = "" It shouldn't matter if I use the same variable name; one is a global variable and the other is a session variable. This report opens without any issues when called from nearly identical code on a page that has a gridview and a button that opens this report. I need to be able to also open it from a report index page. The issue is why doesn't it load the session variable "strSQLFilter" the first time

• Re: Datatable to Excel or GridView to Excel

  So does mine. I use a master page and my page does not explicitly use "form", but instead has <asp:content...> And it works. Have you tried it? If you have and it's not working then maybe the difference is between asp.net 2.0 and asp.net 3.5.

  Try using this code converter: http://www.developerfusion.com/tools/convert/vb-to-csharp/ I use to run code the opposite direction quite often and it's very good.

• Re: Datatable to Excel

  I've recently done this. FYI: The open/save dialog box will open automatically and if the user chooses "Save" they will then get the "Save As" dialog box. On the page: < asp : ImageButton ID ="ImageButton1" runat ="server" ImageUrl ="images/excel.jpg" Width ="40" Height ="40" ImageAlign ="Middle" /> In the code behind: Public Overloads Overrides Sub VerifyRenderingInServerForm( ByVal control As Control) End

• session variable doesn't load on first button click

  I am trying to open a report from a page that allows the user to filter the querystring if desired. When clicking the button to run the report Session("strSQLFilter") is always behind by one click. On the page: < asp : Button ID ="lnkStatusRpt" runat ="server" Text ="Run Status Overview Report" OnClick ="openStatusReport" CausesValidation ="false" Visible ="true"></ asp : Button > Code behind: Protected Sub Page_Load

• Passing Querystring via HttpUtility.HtmlEncode or Server.UrlEncode

  Hi, I need to be able to pass a querystring that is built dynamically depending on the user's criteria selection to a report. An example of the querystring: strSQLFilter: WHERE Status = 'Closed' I've tried the following: Dim theURL As String = "reports/statusOverviewReport.aspx?strSQLFilter=""" & strSQLFilter & """" Dim theURL1 As String = "reports/statusOverviewReport.aspx?strSQLFilter=""" & Server.UrlEncode

• Re: Need to check for DBNull prior to formating field in listview

  Thanks! That was exactly what I needed. Here is the code: <% # IIf(IsDBNull(DataBinder.Eval(Container.DataItem, "conclusionStatement" )), "" , (DataBinder.Eval(Container.DataItem, "conclusionStatement" )))%>

• Re: Need to check for DBNull prior to formating field in listview

  About VB IIF function: Because the VBScript runtime will evaluate both falsepart and truepart before passing them to the function, both expressions must be valid, even if just one will execute. Now what?

• Re: Need to check for DBNull prior to formating field in listview

  Thanks, I think it's closer, but I get the following error now. Conversion from type 'DBNull' to type 'String' is not valid. < p > Detail: < blockquote > <% # IIf( TypeOf (Eval( "conclusionStatement" )) Is DBNull, "" , String .Format(Replace(Eval( "conclusionStatement" ), Chr(13), "<br />" )))%> </ blockquote ></ p >

• Need to check for DBNull prior to formating field in listview

  I have field in a listview that can sometimes be empty. I am replacing the carriage returns with <br /> tags for display on screen. Because this is not a required field it throws this error when the field is empty. Is there a way to do an if/else test to check for DBNull inline? Conversion from type 'DBNull' to type 'String' is not valid. < ItemTemplate > < p > Detail: < blockquote > <% #String .Format(Replace(Eval( "conclusionStatement" ), Chr
