Dropdown menu - Null or empty string??


I have drop dowm menu as follow.

<asp:ListItem Value="">none</asp:ListItem>
<asp:ListItem Value="STO">Stock</asp:ListItem>
<asp:ListItem Value="ORD">Order</asp:ListItem>

If I chose none, it stores data as "Null"

If I Query the data as below, I don't get the data has value of "Null"

SELECT tabale From type Where type <> STO or type <> ORD

I get data that has empty string but not Null.

Here is my question.

1, How do I write dropdown menu value in oder to get empty string instead of Null?
I did <asp:ListItem Value="">none</asp:ListItem> but this stores Null.

2, Why this Query won't pick up Null?
SELECT mytabale FROM type WHERE type <> STO or type <> ORD

Thank you for your help.

validate and hidden fields

Here is my dilemma, I have a web page that I hides and shows textboxes based off a selection within a dropdown. The dropdown shows Yes/No, if they select NO they see one set of textboxes to fill out, if they select YES they see a different set of textboxes, once they're done, they click submit which does validation. Here is my issue. ALL textboxes are required, so how can I not validate the textboxes that are not showing on the screen? I'm hiding them like this: var show=""; function show(o) { if (show != "") show.style.display = 'none'; if(o.selectedIndex>0) { var d=document.getElementById(o[o.selectedIndex].value); d.style.display='block'; show = d; } } and I call that from my dropdown. onchange="show(this);">   and I have this in my HTML <tbody id="N1" style="display: none;"> </tbody> and I have textboxes within the N1 tag, I also have an N2 tag that shows if YES is selected.each tag has required textboxes, how can I not validate the textboxes if they are not showing on the screen and are in the hidden N tag?

How to make Hidden Fields appear on every other page when there are other data regions exist on the

Dev Environment: Visual Studio 2008 Client reporting(.rdlc) I have a client report with one hidden field and one table. The data for the hidden field come from one dataset and the data for the table comes from another dataset. Since there is huge data on the report, the table data spans multiple pages. at the same time i want the hidden field to appear on every other page along with table. i'm using these hidden for report header purposes. As an alternative i have used hidden parameters instead of Hidden Fields. Are there any alternatives other than this ? -- Praveen

hidden fields


we have a web application developed with .net 2.0 framework. The home page is instrumented with master page. I see an hidden control name as "__LASTFOCUS" in the view source of the home page. I dont know how it is getting generated. I never declared it in aspx/cs page as well.  I looked at the entire solution but i couldn't find explicit declaration of the field. Any idea how to track that field? 

Append an Item to a SP List and NewForm dropdown menu


When Lookup Column on a NewForm.aspx, that was populated from another SP List, does not contain a value in the DropDown menu can it be added/inserted into the source SP List from the NewForm without leaving the NewForm? 

Is there code or example how to insert the Item in the SP List, then refresh/repopulate the Lookup Column's DropDown menu (in the NewForm)?

Or is there a better way to do this add an item both the List and the dropdown without resetting the values already entered in the NewForm?

Context Menu not listing all fields issue with ie7



We have a Sharepoint 2007 installation using performance point reporting for our main system. Because of legacy systems our endusers are using IE6 and all works correctly. Recently we have moved some end user browsers to IE7 and this has had an effect on our reports.

In IE6 we can drilldown using the context menu in Analytic  graphs and Analytic datagrids, which displays all of the fields that are part of the cube. If most cases it displays about 20 fields that can be used to slice the information as we require it.  Using IE7 we can still drill down but the list of fields displayed is much shorter, usually 4 or 5. 

Is there a setting or fix we need to apply to IE7 to display the full list of fields in the context menu?

webpart to open link and prepend hidden htlm fields to hosted payment site


I have an almost completed application based on SharePoint 2010 and InfoPath 2010 forms. I think what is now needed is a custom webpart that will bring in 3 web part connection parameter fields from the forms in SharePoint, open a link to an HTML site, and prepend some static and dynamic HTML to the stream and open a new window that will allow a user to enter credit card data into the https site thus opened. Next is to write back the results of the transaction to a form column paid_in_full yes/no, that I in turn can release the goods to the user.

Any suggestions as to how to accomplish this in a web part or other is greatly appreciated!



Sub sites showing at top level on quick launch menu


After making a number of Teamsites, I am experimenting with Publishing sites.  I am experiencing odd behavior in the Quick Launch and don't know if this is a function of the Publishing template or one of the configurations I have tinkered with.  The problem is that when I make a new site in my collection, the site name is displayed in the quick launch in the same heirarchy as Sites, Lists, Documents, etc., instead of showing up UNDER the Sites category.  Can anyone advise please?
