How to Make Changes to Multiple Items at Once

If you only have a few channels on your system, or are just tweaking a couple electrodes in your setup, then changing each item individually is probably the best option. But what if you have a 256 channel __lynxsx_hardware_name system and want to change the low cut filter for all 256 channels? The Properties Page allows you to accomplish this by making changes on groups of items. Each of the tabs of the property page will give you different multiple item change options, by grouping items differently. The same rules that apply to making a change on a single item also apply to multiple item changes. Here is an overview of how to make multiple item changes:

Global Selections

The Properties Page places items in a tree into groups based on shared properties of the items. Changing all items in a group is referred to as a global change.
  1. Click on a root node of the tree view. All of the items underneath the root node will be affected when a property is changed.
    When the Properties Page Acquisition Entities tab is selected, all of the items are grouped by their acquisition entity type. Selecting a type allows you to globally change the properties of all of the acquisition entities of the selected type When the Properties Page Display tab is selected, all of the items are grouped by their Plot Window. Selecting the window allows you to globally change all plots and the properties of the acquisition entities whose plots are in the window.

    If the root node contains items with differing properties, you will see the items broken down into sub trees. Selecting a sub tree will allow you to apply global changes to all the items in the sub tree. There are options that can be globally set when selecting a sub tree that are not available when selecting a root node. For instance, in the below image you will be able to change all of the CSC properties of the items below CSCs. If "Time Window 1" were selected, only the window and plot properties could be changed.

  2. Not all properties are available when trying to make a global change. If a property is unavailable, for any reason, it will will either be grayed out or not shown. The headers of all sections that are under global control will have **GLOBAL** added to the front of the section title, and all status information will have be changed to the word GLOBAL. Any changes you make will automatically change all of the items beneath your current selection in the tree view. All of the rules that apply to changing a single item also apply to changing multiple items. You will want to see the reference guide entry for the specific item type you are trying to change for more information on that setting.


Multiple Selections

If changes to only a few particular items are desired, you can select only the items that you want to change. As with global selections, not all options are available when multiple items are selected. If an property is unavailable, it will either be grayed out or not shown. The values shown in the properties are those of the most recently selected item.

__prod_name supports standard Windows multi-select semantics, using the Ctrl and Shift keyboard modifiers.
Holding down the Ctrl key and left clicking the mouse will allow you to select individual items without selecting items in between. Clicking on an already selected item will deselect the clicked item. Attempting to select an item in a different subtree will deselect all previously selected items. In the above image, selecting CSC1 will deselect SE2, SE4 and SE6. If using the up and down arrow keys to select items, there is no difference between using the Ctrl and Shift modifiers.
After selecting an initial item, you can hold down the Shift key and left click the mouse on a second item to select all items between them. The above selection was made by clicking on SE2, holding down Shift and then clicking on SE5. Attempting to select an item in a different subtree will deselect all previously selected items. In the above image, selecting CSC1 will deselect SE2, SE3, SE4 and SE5. If using the up and down arrow keys to select items, there is no difference between using the Ctrl and Shift modifiers.
