ssrs 2008 R2 - report parameter with no default set throws java script error

We have recently upgraded from SQL Server 2008 to SQL Server 2008 R2....I am experiencing a problem with my report parameters on my SSRS reports. It seems that my report parameters that I do not have a specified 'default' value throws a java script error when I try and run/render the report under R2.  As soon as I put a 'default' value on the report param, everything is fine.  However, that is not the behavior we need for our reports...the user needs to pick their selection. Can anyone shed some light on this, it seems to be an AJAX problem...I need to be able to have report parameters with a list of values, but no 'default' value on the parameter.

How to disable fields in a GridView when you change the listbox options?

 Hi all I am trying to apply the same logic I applied to a FormView. Here is what I do:I have a DropDownListBox as one of my FormView fields and when I choose a specific option the fields inside my FormView are enabled/disabled according to the options chosen. Well I havent been able to apply that concept to a GridView. Here is my code to the FormView:protected void ItemFormView_DataBound(object sender, EventArgs e) { DropDownList ddlConfigType = ItemFormView.FindControl("ddlConfigTypes") as DropDownList; if (ddlConfigType != null) { if (ItemFormView.CurrentMode == FormViewMode.Edit) { DisableNAFields_EditMode(ddlConfigType.SelectedItem.Text); } } }private void DisableNAFields_EditMode(string configType) { TextBox txtboxScope = ItemFormView.FindControl("txtboxScope") as TextBox; if (configType == "registry") { txtboxScope.Enabled = false; } } Is there a GridView mode enumeration? How do I achieve the same goal? Thank you

Hi Experts, Following script works perfect (refresh only once after 5 seconds and stops but for some reason if somebody clicks next month then it keeps refreshing for 5 seconds. Can you please put the following code in your calendar.aspx page and check if you can get rid of the continuous refresh if somebody selects next month otherwise it works fine. Please provide the updated script <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"> <title>Refresh test</title> <script type="text/javascript">   window.onload=function(){     url = window.location.href;     qIndex = url.indexOf("?");     if( qIndex != -1 ){       getData = url.substr(qIndex+1, url.length-1);       if(getData != "refreshed=1"){         refresh();       } else {         myDiv = document.getElementById('content');         myDiv.innerHTML = "This is the second and final time the page loaded.";       }

Script Component - Change One Row Input to Multiple Row Output

Hi All I am new to SSIS, and looking for help. I do not know if it is possible, but I like to try using the "Script Component" to change a input like this:   1234 1235 1236 ...   to and output like this:   1234, Value1 1235, Value2 1235, Value3 1235, Value4 1236, Value5 ...   Depending of the input value, 1 or more Rows are pushed out the Output, Like the value 1234 -> result in 1 Row in the output, where the value 1235 -> result in 3 rows in the output. Is this possible to do in a Script Component?? If it is how do you program such behavior? Do some good sources to learn SSIS exist out there?? I think it is not easy to find information.

Drop Down Listbox SelectedIndexChanged Event not firing when I programmatically change selection

I have two drop down listboxes (DDL1 and DDL2).  When DDL1 has an index change, DDL2 then has a refresh of list items based off SQL Server SELECT from a table.  The database isn't the problem.  Everything works perfectly when the user selects a new item manually from DDL1.But in my code, I save the user data from the selection of DDL1 in a separate table.  And then upon rendering of the page (Page_PreRenderComplete), I do a SelectedIndex assignment of the value of what's saved in the db table.  That works just fine, it selects the DDL1 item, but DDL2 is unaffected, as if DDL1's SelectedIndexChanged event isn't called like it would be if manually changed.  How can I get around this?Thanks in advance. :)
