Using Rules to populate a textbox based on other values.

  

I am building a web-friendly form in Infopath (little new to the software)...

I have been able to hook up my form to my SharePoint and pull in user data so I can pre-populate various fields.

One field is not in our Profile services (nor Active Directory).  I'll call it Company Code.

But you can determine Company Code by checking the Company and Department.

Something like:

Company = "ABC", Department = "123" then Code = "XCV"
Company = "ABC", Department = "456" then Code = "VCX"

etc...

Since I am successful pulling the Company and Department from the Webservice.

I figured I build a text-box and put 30 or so rules on it to analyze the contents of Company and Department to determine what should be in the text-box.
So I used Conditions to check the Comany and Department and then the rule set the contents of the Company Code box.

However it seems as though the rules never run. 

And I got to thinking, when DOES the rule know when to run?  I don't see an "onchange" event or anything (trying to avoid code for web-friendly anyways) - so....

I do have the Company and Department fields populate immediately when the form is opened, but is that early enough for the rules?

Do the rules have to manually tri

How to bind distinct values to DropDownList from DataSet (as a result of a web service call)?

  

Hi there,

I'm trying to bind a dataset (where the data is coming from a webservice) to a dropdownlist; the problem is that I'm getting duplicates in the list... how can I display distinct values only:

drp_Brand.DataSource = ds.Tables[0];
            drp_Brand.DataTextField = "Brand";
            drp_Brand.DataValueField = "Brand";
            drp_Brand.DataBind();


Thanks!

Retain DropDown,TextBox's previously selected values after redirected from another page.

  

 Hi People, How are you all doing?

I have 2 pages one is SearchPage & It has DropDowns, textboxes to specify the search criteria. From the search result the user is redirected to another page when he clicks the hyperlink in the search result  where he fills in the information and again redirected to SearchPage. Now the SearchPage is posted back with no state i just want to retain the search criteria and display when user comes back. Please give me some suggestion how to get this done. I've used ViewState to save the values and check them in Page_Load but they are null.   

Thanks

Abid

DropDownList to display values from Two Tables - bold sub heading and normal Text

  
Hello I hope I am not asking simple one.  SUPPORT SERVICES<     Computing Service    Library or Data Engineering    Civil Engineering    Electrical Engineering  I have the data to display in a DropDownList control shown as above. There is a distinct category Type(example Support Services) and Category Name i.e., Computing Services. I do not want to hard code the values into DropDownList control. I like to get the data from database to display as shown in above Table. Note that Category Type should be displayed in Bold and Category Name in normal Text. Question: In order to achieve the above, 1. How many database Tables and relationships between them  2. Query the data to display in the above format in drop down 3. how should be the code behind i.e, DataTextValue and DataValueField for DropDownList. Please provide with useful code snippets or references. Thanks,

Accessing a row's dropdownlist values AFTER the gridview control is in Edit mode

  
Hello, I have a gridview control. When it goes into Edit mode, there are 3 dropdownlists in one cell that are populated by separate stored procedures during the RowDataBound event. The 1st dropdownlist's value is used as a parameter to determine what the 2nd dropdownlist is populated with. The 2nd dropdownlist's value is used as a parameter to determine what the 3rd dropdownlist is populated with. Everything works fine when the row is first put into Edit mode. While I'm in Edit mode and I change the selection in the 1st dropdownlist, how do I access the control so I can feed this new parameter to the 2nd dropdownlist? I have the first 2 dropdownlists set for AutoPostBack so that the Page_Load event is fired when the user changes a value. I know how to get access to these controls via the FindControl method when the row is being databound but how do I find the control during the Page_Load event? Thanks for any help!!!   Penny  

SSRS Report based on SSAS Cubes doesn't show NULL values correctly

  
I have a SSRS report which is based on an SSAS Cube. In the Cube the formating of numeric fields that NULL values are properly shown as NULL values. In the Cube Browser and Excel this is shown correctly. However when I design the report already the query against SSAS shows these fields as "0" instead of NULL. Is there a way to fix this or is this a bug ?
