Add a checkbox column to the briskdatagrid

After a checkbox column is added to the briskdatagrid, each cell in the column is displayed as a checkbox. To add a datagridcheckboxcolumn like a briskdatagrid, you must first declare a datagridcheckboxcolumn object. Then, use the addcheckboxcolumn () method of the briskdatagrid to add the object to the briskdatagrid. The following is a prototype of the addcheckboxcolumn () method:

Public sub addcheckboxcolumn (_

Byval checkboxcolumn as datagridcheckboxcolumn ,_

Byval mappingname as string ,_

Optional byval headertext as string = "",_

Optional byval [readonly] as Boolean = false ,_

Optional byval width as integer = 75 ,_

Optional byval allownull as Boolean = false ,_

Optional byval truevalue as object = true ,_

Optional byval falsevalue as object = false)

Me. briskdatagrid. setdatabinding (dvemployee)

Me. briskdatagrid. begintablestyle ("employees ")
