Using custom UI controls in extensions 59
To add a database tree control to a dialog box, you can use the following sample code with
appropriate substitutions for quoted variables:
<select name="DBTree" style="width:400px;height:110px" ¬
type="mmdatabasetree" connection="connectionName" noexpandbuttons
showHeaders></select>
You can change the connection attribute to retrieve selected data and display it in the tree.
You can use the
DBTreeControl attribute as a JavaScript wrapper object for the new tag.
For more examples, see the DBTreeControlClass.js file in the Configuration/Shared/Common/
Scripts folder.
Adding a variable grid control
The variable grid control has the following attributes:
The following example adds a simple variable grid control to a dialog box:
<select name="ParamList" style="width:515px;" ¬
type="mmparameterlist columns"="Name,SQL Data ¬
Type,Direction,Default Value,Run-time Value" size=6></select>
The following example creates a variable grid control that is 500 pixels wide, with five columns of
various widths:
<select name="ParamList" style="width:500px;" ¬
type=mmparameterlist columns="Name,SQL Data Type,Direction, ¬
Default Value,Run-time Value" columnWidth="100,25,11," size=6>¬
</select>
This example creates two blank columns that are 182 pixels wide. (The specified columns total
136. The total width of the variable grid control is 500. The remaining space after the first three
columns are placed is 364. Two columns remain; 364 divided by 2 is 182.)
This variable grid control also has a JavaScript wrapper object that should be used to access and
manipulate the variable grid control’s data. You can find the implementation in the
GridControlClass.js file in the Configuration/Shared/MM/Scripts/Class folder.
