Select All GridControl columns and check boxes, and select all gridcontrol columns.

Select All GridControl columns and check boxes, and select all gridcontrol columns.

Note:

Add a column to GirdControl. This column is not written in the database, but added in the code.

Foreground call:

Note: Before GridControl is bound, manually add a column. After adding a column, bind the column.

// Add a column of dt. columns. add ("chk", System. type. getType ("System. boolean "); dt. columns ["chk"]. defaultValue = Boolean. falseString; gridControl1.DataSource = dt; Functionjsj. gridCheckEdit (gv, "chk", 50 );
