I've tried a few different ways but none seem to insert NULL, the one below still inserts "", can anyone point me in the right direction.
Here is the required part of the code, if you require more just let me know.

Forms Data Controls :: Detailsview Mode Updates Read Only Field To Null Or Empty
Sep 10, 2010I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

SQL Server :: Query To Return Results Based On Latitude / Longitude Within Certain Radius
Sep 7, 2010I cant seem to find a good example of how to build the query logic. We are allowing users to search based on lat/long and need to add radius as another parameter. So you enter 29.30125 as the latitude and -95.04590 as the longitude and pick say 15miles as the radius, i need to return all records that fall within that radius.. can someone suggest a good site to review this type of query?
View 1 RepliesDataSource Controls :: SQL Server First Full Text Search Takes A Long Time To Return Results?
May 19, 2010I am working on a website hosted with GoDaddy, SQL Server 2005. I have a table in my SQL Server database with a full-text index. On my website, a user can type in search terms and the terms are then passed to a stored procedure in the database which performs the search. The first search takes about 45 seconds to get results. Subsequent searches return results immediately. I found a description of this problem in a Microsoft knowledgebase article:http://support.microsoft.com/kb/915850/en-usGoDaddy tech support says I need to purchase a dedicated server to make the changes suggested in this article.Surely there is some other solution. Does anyone know how to avoid this delay without changing the server configuration?

View 2 RepliesForms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?
Dec 6, 2010I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?
I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

Web Forms :: How To Use Server Side Validation To Ensure Image Field Is Not Null
Aug 20, 2010I'm having trouble accomplishing the above. Below is all the mark up and code. I'm not getting error messages, but the validate image function is not working (fileupload portion is working ok).
In my attempt below---not sure if it's the simplest or best validation approach anyway---the "UserId" parameter appears during rendering to be empty---but in most methods I have it successfully containing or referring to the logged-in user's identification.
Following is the control that refers to the image field (page = advertisement.aspx):

Web Forms :: Required Field Validator Not Catching Empty Field?
Feb 3, 2010I have a aspx page with a ascx control inside an ascx control and the required field validator is not hit on the action of the page.
The issue is with the 2nd nested ascx control. The field validators in the first ascx control validate correctly, but with the ascx control inside the ascx control there are issues.
The nested ascx control is a repeater control and this may be the reason, but I am unsure.
I'm not exactly sure what question to ask, but I'll list a few below.
How do I attach the field validators up a level to the 1st ascx control?
Is it possible to put required fields into a nested ascx control?
Forms Data Controls :: A Required Input Field DropDownList If Old Records Have Null In This Field?
Apr 1, 2011I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

View 2 RepliesSQL Reporting :: Return The Results Of A 1 To Many Relationship?
Aug 31, 2010A co-worker of mine just came back from a SQL Server Reporting Services class (we are using SQL Server 2005). In that class they were told that if they had a one to many relationship that they would have to flatten the results into one row of the resultset in order to show the 'many' portion of the relationship. For example, my company has two tables:Jobs Notes/Memo'sor each Job we can have 0 or more Notes/Memo's.According to my co-worker the Report Server must have each of the Notes/Memo's in one row of the resultset. That we therefore have to flatten the list of Notes into Note1, Note2, Note3...etc fields.Is this correct? How would I handle a situation where I didn't know how many Notes there were?

C# - Use XMLHttpRequest To Execute A SQL Query And Return The Results?
Feb 9, 2011I'm building a web app for my company that will run a query every few seconds against SQL Server, and the data that it returns is which database is restoring and how much % complete it is. I have the query already set up and it works fine.
What I want to do is on my Web Form, have a "div" element that will contain the % complete of a database restore, and have it update every few seconds using the JavaScript timer object:
setInterval(function, interval)
I figure I would need to use XMLHttpRequest to send the request to the web server which will run the SQL query. Am I on the right track? How would I even start to do this?
My SQL query is below:
Use master
Select der.session_id, der.command, der.status, der.percent_complete, *
From sys.dm_exec_requests as der
Where percent_complete > 0
