GridViewDesigner.GetDesignTimeHtml Method (DesignerRegionCollection)
Assembly: System.Design (in system.design.dll)
public String GetDesignTimeHtml ( DesignerRegionCollection regions )
public override function GetDesignTimeHtml ( regions : DesignerRegionCollection ) : String
Not applicable.
Parameters
- regions
A DesignerRegionCollection to which definitions of the selectable and clickable regions in the design-time view of the control are added.
Return Value
A String containing the markup used to render the GridView at design time.The GetDesignTimeHtml(DesignerRegionCollection) method calls the GetDesignTimeHtml method to generate the markup for the design-time rendering of the GridView control. The GetDesignTimeHtml(DesignerRegionCollection) also populates regions with a DesignerRegion object for each clickable or selectable region of the design-time rendering.
For the GridView, the first cell in each row is selectable; all the cells in the rows are clickable.
Notes to Inheritors: If you override the GetDesignTimeHtml(DesignerRegionCollection) method, be sure to call the base method or the GetDesignTimeHtml overload, because they eventually, through several override levels, call on the GridView control or a copy of the control to generate the markup.The following code example shows how to override the GetDesignTimeHtml method in a class that is inherited from the GridViewDesigner class to change the appearance of the GridView control at design time. The example adds a new first row to the grid to contain the Caption property, if the Caption is defined. If the BorderStyle property of the control that is derived from the GridView class has the NotSet or None value, the GetDesignTimeHtml draws a blue dashed border around the control to make its extent more visible. It does not change the run-time appearance of the control.
