http://bugzilla.novell.com/show_bug.cgi?id=557223#c0 Summary: System.InvalidCastException after second postback on a customize control. Classification: Mono Product: Mono: Class Libraries Version: 2.4.x Platform: x86-64 OS/Version: RHEL 5 Status: NEW Severity: Normal Priority: P5 - None Component: Sys.Web AssignedTo: [email protected] ReportedBy: [email protected] QAContact: [email protected] Found By: --- Blocker: --- Created an attachment (id=328691) --> (http://bugzilla.novell.com/attachment.cgi?id=328691) Test Case User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.15) Gecko/2009101601 Firefox/3.0.15 (.NET CLR 3.5.30729) Adding controls and setting styles, in a particular way, to datagrid pager, inheriting the control from base dataGrid, ends in a System.InvalidCastException during second postback, when it's rebuilt from viewstate. It seems to be a very singular issue, I was not able to reproduce the error using other types of controls, but maybe it can be a general problem so I decided to report. Reproducible: Always Steps to Reproduce: 1. Use the attached files to create a webapp that reproduce the problem 2. Click on linkbutton, the datagrid is shown. 3. Clink on a link of your choice. Actual Results: System.InvalidCastException: Cannot cast from source type to destination type. at System.Web.UI.StateBag.LoadViewState (System.Object savedState) [0x00007] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/StateBag.cs:85 at System.Web.UI.Control.LoadViewState (System.Object savedState) [0x00006] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:891 at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState) [0x00033] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:1686 at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState) [0x000a2] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:1700 at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState) [0x000a2] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:1700 at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState) [0x000a2] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:1700 at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState) [0x000a2] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:1700 at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState) [0x000a2] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:1700 at System.Web.UI.Control.LoadViewStateRecursive (System.Object savedState) [0x000a2] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Control.cs:1700 at System.Web.UI.Page.LoadPageViewState () [0x00046] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Page.cs:1926 at System.Web.UI.Page.RestorePageState () [0x00051] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Page.cs:1558 at System.Web.UI.Page.InternalProcessRequest () [0x001b9] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Page.cs:1533 at System.Web.UI.Page.ProcessRequest (System.Web.HttpContext context) [0x0005b] in /usr/src/packages/BUILD/mono-2.4.2.3/mcs/class/System.Web/System.Web.UI/Page.cs:1353 Expected Results: It should run.
