Overview

By default, WDMap displays the records found in a data file by using the following rules:

All the records found in the data file are displayed.
The records are sorted according to their creation order in the data file.
All items found in the data file are displayed (except the for "Composite key" items).
The items are organized in logical order. The logical order corresponds to the display order defined in the data model editor.

However, you have the ability to modify:

The selection of information to display. Indeed, WDMap allows you to select:
- the records to view,
- the items to view.
The display options of viewing table:
- search for records,
- sort of displayed records,
- modification of display order of items,
- anchoring columns on the left of table.

Viewing a selection of records only

To simplify your searches, WDMap allows you to display the records corresponding to a specific criterion.
For example, you have the ability to display the customers leaving in "Boston" or the suppliers whose name starts by the letter "F".

Two methods are available:

Direct input of one or more selection criteria on the file items ("Display .. Selection of records ..Wizard" or Ctrl + Q).
Using an SQL query on the file records ("Display .. Selection of records .. SQL query").

Remark: These selection criteria are not saved. During a next use of WDMap, you will have to redefine these criteria in order to perform a new selection.

Showing some items only

If your data files contain several items, WDMap allows you to only display the items required by your search.

For example, if your "Customer" file contains more than 20 items, you can choose to see the last name, first name and city of each customer.

To select the items to view, select "Display .. Selection of columns to display" (or press Ctrl + O) and check the items to view.

Remark: This selection criterion is not saved. During the next use of WDMap, you will have to redefine this criterion in order to perform a new selection.

Configuring the viewing table

Overview

In WDMap, the records are viewed in a table. Therefore, all the options specific to this type of control are available.

Finding records

A "Starts with" search can be performed on a key item.

The columns where a search can be performed are identified by

To find records according to the value of an item:

Click found in the column header. An input area is displayed.
Enter the value of the item to find. The records that start with the letters typed are dynamically displayed.

Remark: This search criterion is not saved. During the next use of WDMap, you will have to redefine this search criterion.

Sorting the viewed records

A simple sort can be performed on an item (ascending or descending order).

For example, you can sort the suppliers according to their city.

Sortable columns are identified by the

icon.

To sort the viewed records according to an item, click the column header.

Remark: This sort criterion is not saved. During the next use of WDMap, you will have to redefine this criterion in order to perform a new sort.

Modifying the display order of items

By default, the display order corresponds to the logical order of the items. The logical order corresponds to the display order defined in the data model editor.

WDMap allows you to easily modify the display order of items.

For example, you can organize the columns in order of importance or group the columns that contain the same type of information.

To move a column:

Click the column header and keep the left mouse button down.
Move the column to its new position and release the left mouse button.

Remarks:

This display order is not saved. During the next use of WDMap, the order used will be the default order (logical order of items).
The "Rec #" column cannot be moved (this column corresponds to the number of the records in the data file).

Anchoring columns on the left of table

By default, to view all the columns, you must use the horizontal scrollbar.

WDMap allows you to fix the columns on the left of the viewing table. When using the horizontal scrollbar, only the non-fixed columns will move.

Therefore, the columns containing the most important information can always be visible.

For example, if the "CustomerName" column is fixed on the left, the customer name will remain visible when using the horizontal scrollbar.

To fix a column, hover the left side of the header of the column to fix and click when

appears.

To unfix a column, hover the left side of the header of the column to fix and click when

appears.
