Unable to change autogrowth properties of SQL Server 2008 data and log files


I have used the GUI and the CLI to attempt to change SQL Server 2008 log file autogrowth property all to NO avail. In other words, there are NO error messages of any kind, indeed the CLI reports that the command completed successfully. But re-examining the database properties shows that NO change was effected.

For the CLI command, I have used the following with dots filled in for my database and logfile:


Why doesn't this work? How to make it work?


How do you change the Boundfield Data Properties for CURRENCY to display a pound (or other) sign ins


Probably a Q more suited for a SQL forum, but I guess it comes up a fair bit in ASP.net web site design?

Hopefully the answer will be straightforward...

Thanks in advance.

Bug: Does not change column type from nvarchar to ntext


Scenario: If you create a table with a column of type nvarchar, populate it with some content and try to modify it using the WebMatrix editor, from nvarchar to ntext, it does not display any error message or warning that this is not possible. It silently saves and reverts the change, back to nvarchar. Wasted some hours on this issue as I thought my column was ntext, but in fact was still nvarchar.

Expected behavior: It should change to ntext, or if SQL CE doesn't support that, it should notify the user that no change was applied.

How to change the default page base class?


I've tried setting the <pages pageBaseType="DynamicWebPage" /> value in web.config, but when I response.write out the page type, I'm still getting Microsoft.WebPages.WebPage.

I'm simply trying to sub-class WebPage and add some additional functionality such as a dynamic PageData dictionary similar to Phil Haack's dynamic ViewData dictionary.



Rendering data with HTML tags in the DD Gridview for a selected column


I am having trouble finding out where and how to HTML Encode a cell's data on the Dynamic Data (v4.0) gridview of List.aspx.  As a simple case, suppose I have formatted cell data that is A<br/>B in the DB.    Obviously, I want A stacked on B in the cell.

It seems gridView1.HtmlEncode = true has gone away.

So maybe I'll try to catch it on the RowDataBound event:

protected void GridView1_RowDataBound(Object sender, GridViewRowEventArgs e)

            if (e.Row.RowType == DataControlRowType.DataRow)
                // Html Encode the cells


but this event never fires?

Has anyone figured out how to properly render HTML tags data in the List.aspx's GridView1? 

If I figure this out, then I can add a MetaAttribute called something like [EncodeAsHtml(true)] and be on my way.  Thanks!

dynamically change column names in Crystal reports


I need to develop 3 pages.

On the first page user defines atmost 7 column names to be displayed on the report. I'm saving these names in a Sql DB table 'Columns' with Column_Nm and Column_ID as Table columns.

On the second page I'm retrieving column_Nm from the table and displaying them on the page so that the user enters the data. This data is saved in another table 'Summary' with the Columns column1 through column7.

on the 3rd page I need to show a report of 'Summary' table.

How do I dynamically replace column1 through column7 names with that of 'Column_Nm' on the report?

Any help/suggestions would be appreciated.

Change data on gridview bind


Hi there,

Simple little problem. i have a gridview that shows products assigned to a customers job. They are displayed in exVAT prices. To make it easier i want to show the inc VAT prices. How can i add VAT to 1 column in this table?

split one data column into many?


Hi, I've a database table contains survey questions and answers. But the problem is both 'question' and 'answer' are saved in the same column(like below).

SubmissionDate                                                          Submission

2010-02-15 14:53:59.657                     ***What's your pet's name?***  Lili ***Tell us about yourself*** I'm a teacher

2010-02-15 14:53:59.657                     ***What's your pet's name?***  Lucy ***Tell us about yourself*** I'm a five star cook

I'd like to use a simple datagrid to display the survey result, but I need to separate the submission column into multiple columns ('question' as column name, 'answer' as data)

the number of questions or questions being asked are different for each survey so they are not fixed. 

Is it even possible to get something like this below in a gridview?

I am building a website for my hockey league.


I have a gridview that displays the current weeks scheduled games. Ideally I have added a column to the end of the gridview that I would like display 1 of 3 values. If the game has already been played I would like to display the score of the game; if the game has yet to be played I would like the column blank and if someone on either team has indicated that they can't make the game I would like to display a button that says "subs needed" and take you to another page to sign up to be a sub. Can this be done? I have been able to change the background color of the line based on the two boolean flags from the database using the RowDataBound event handler but I can't seem to find a way to set the value of a specific field in my row. (The background is set for the whole row.)

Thanks in advance -eric

Business Data Column cascade


Good afternoon, I would like to know if is possible to have two business data columns linked to each other. This is the scenario that I want:

BD Column 1 called State with all US states

BD Column 2 called City with all the cities based on the state selected on BD Column 1

Use BDC data in list as multi-select column

I have a document library that uses values from another system for its metadata.  Right now, we copy the values from the primary system into SharePoint so users can choose them.  I want to find a way to use the BDC connection that I have set up to automatically pull those values.  The problem is that the current metadata is set to multi-select.  So, I have a file that is in the library and it can be used for multiple clients - clients is a column in my library and users can select many entries.  When I set up a column to pull BDC data, it only allows single entry.  Does anyone have any ideas?
