SYMPTOMS

In Microsoft Office FrontPage 2003, if you filter a Data View from multiple filtered Data Views, you may experience unexpected results. When you view the final filtered results, the data is incorrectly filtered. The following diagram provides a sample scenario, where Data View 4 is a filtered Data View that is derived from previously filtered Data Views:
                 Data View 1
	        |           |
          Filter            Filter
            |                  |
      Data View 2	   Data View 3
            |                  |
	  Filter	    Filter
                |           |
		 Data View 4
In this example, when you configure a Web Part connection from Data View 2 to filter Data View 4, and then you configure a Web Part connection from Data View 3 to additionally filter Data View 4, the filtering information from Data View 2 may be lost.

Note A Data View is also known as a Data View Web Part.

CAUSE

This behavior may occur if both of the following conditions are true:
  • You filter a Data View from multiple filtered Data Views.
  • FrontPage 2003 filters the Data Views through the Web Part connections by using the Filter View Using Data Values From action.
When both of these conditions are true, when you click a hyperlink in one of the middle-tier Data Views in the filtering chain, the data that is sent from that Data View may inadvertently clear the filter information that is sent from other middle-tier Data Views. This causes the other middle-tier Data Views to send the data in the first row instead of the data that you last specified. Therefore, the final filtered results are not what you expect.

WORKAROUND

To work around this behavior, you can filter data by using the Modify View Using Parameters From action in the Choose the target Web Part and action for the connection section of the Web Part Connections Wizard when you create a Web Part connection. This action permits the Web Parts to set the value of an Extensible Style sheet Language (XSL) parameter through a Web Part connection. You can use the XSL parameter to filter data. This achieves the same effect as the Filter View Using Data Values From action.

To filter data by using the Modify View Using Parameters From action, follow these steps:
  1. Click inside a row of the final Data View.
  2. On the Table menu, point to Select, and then click Row.
  3. On the Data menu, click Conditional Formatting.
  4. In the right pane, click Create, and then click Show content.
  5. Specify the filter criteria.

    To do so, in the Field Name column, click a field name, in the Comparison column, click Equals, in the Value column, click [Input Parameter], and then click OK.
  6. Right-click the middle-tier Data View that you are using to provide the data, and then click Web Part Connections.
  7. If you have an existing Web Part connection, click the Web Part connection, and then click Modify.

    Otherwise, click Add to add a new Web Part connection if the Web Part Connections Wizard does not start automatically.
  8. In the Web Part Connections Wizard, click Provide Data Values To in the Choose the action on the source Web Part to use for this connection list, and then click Next.
  9. Under Choose the page containing the Web Part for the connection, click the appropriate option, and then click Next.
  10. Under Choose the target Web Part and action for the connection, click the target Web Part in the Target Web Part list.
  11. In the Target action list, click Modify View Using Parameters From, and then click Next.
  12. In the Columns in WebPartName column, click the cell that is next to Input Parameter, click a column value to map the field value from the source Web Part that contains the correct data to the input parameter, and then click Next.
  13. Click the column that you want in the Create a hyperlink on list, and then click Next.
  14. Click Finish.
This procedure causes the input parameter to affect the rendering of the XSL Transformations (XSLT) code. The view will appear filtered when the middle-tier Web Part connection is triggered.
