14.AspxGridView column editing style

1.AspxGridView column Type

Gridviewcommandcolumn: command button columns
Gridviewdatacolumn: Basic Data columns
Gridviewdatabinaryimagecolumn: Binary image columns
Gridviewdatabuttoneditcolumn: Edit button columns
Gridviewdatacheckcolumn: check box column
Gridviewdatacomboboxcolumn: Combo Box column
Gridviewdatadatecolumn: Date column
Gridviewdatahyperlinkcolumn: Hyperlink Column
Gridviewdataimagecolumn: Image Column
Gridviewdatamemocolumn: Large text column
Gridviewdataprogressbarcolumn: Progress bar Column
Gridviewdataspineditcolumn: Fine-tuning The Mask column
Gridviewdatatextcolumn: Text column

Where Gridviewcommandcolumn and Gridviewdatacolumn are similar, they inherit from Gridviewcolumn.
The Gridviewdatatextcolumn class inherits from the Gridvieweditdatacolumn,gridvieweditdatacolumn inherited from Gridviewdatacolumn, Other data columns are directly inherited from Gridviewdatacolumn.
Gridviewcolumn is an abstract class, and you cannot declare a field directly as a Gridviewcolumn class.

CellStyle	Gridviewcellstyle	Field style. Read-only.
Collection	DevExpress.Web.ASPxClasses. Collection	The column belongs to the collection. Read-only.
Fixedstyle	Gridviewcolumnfixedstyle (enumeration)	The style when the field freezes. can read and write. Value range: left, fixed; none: not fixed.
Footercellstyle	Gridviewfooterstyle	Footer field style. Read-only.
FooterTemplate	ITemplate	The cell template where the column footer is located. can read and write.
Grid	Aspxgridview	The field belongs to the Aspxgridview. Read-only.
Groupfootercellstyle	Gridviewgroupfooterstyle	The footer field is grouped with styles. Read-only.

3.GridViewColumn server-side approach

method name	syntax	Chinese Description
Assign	Void Assign (DevExpress.Web.ASPxClasses. Collectionitem source)	copies the public property from the specified object to the current field.
isclickable	bool Isclickable ()	determines whether a field can respond to a mouse click event. Returns True when the field has a header or Aspxgridview allow sorting (settingsbehavior.allowsort) or allows the field to drag (Settingsbehavior.allowdragdrop), otherwise false is returned.
setcolvisible	void setcolvisible (bool value)	sets whether the field is visible. Equivalent to the Visible property.
setcolvisibleindex	Void setcolvisibleindex (int value)	sets the order in which columns are displayed. Equivalent to the Visibleindex property.
autofilterby	Void Autofilterby (string value)	automatic filtering based on specified field values

(1) Examples of assign methods
Note After you call the Assign method, the current field includes the name, and the data is consistent with the replication source. If you want to make some properties, such as post-replication data, different from the replication source, you should re-change after calling this method. Typically used to dynamically create columns.
Cases:

Gridviewdatacolumn C = (gridviewdatacolumn) ( This. aspxgridview1.columns["Creator"]); This. aspxgridview1.columns["Creator"]. Assign ( This. aspxgridview1.columns["Logid"]); C.fieldname="Creator"; C.name="Creator"; C.caption="Creator"
