DataGridView Right-click menu

recently has been in the DataGridView, the previous article got a check box to delete, but later think, if I delete every row, then I delete every time you have to select, and then the area of a single delete, too troublesome, so I remembered to get a right button to delete, and then added a right button discoloration, Anyway is a right-click menu, the bottom bar code to everyone, very simple code, is really very practical.

 <summary>////Add a table////</summary> public void adddatatable () {D            Atacolumn dc = new DataColumn ("ID"); Dt.            Columns.Add (DC);            DC = new DataColumn ("name"); Dt.            Columns.Add (DC);            DC = new DataColumn ("Age"); Dt.            Columns.Add (DC);            DC = new DataColumn ("sex"); Dt.            Columns.Add (DC); Assigns a DataTable value for (int i = 0; i < 6; i++) {DataRow row = dt.                NewRow ();                row["ID"] = i;                row["name"] = "Menghaibin";                Row["age"] = i + 10;                row["Sex" = "male"; Dt.            Rows.Add (row); }}///<summary>///Get the coordinates of the currently selected unit///</summary>//<param name= "Sender" >&lt ;/param>//<param name= "E" ></param> private void Datagridview1_cellmouseenter (object sender       , DataGridViewCellEventArgs e) {     var DGV = (DataGridView) sender;            CurrentRow = E.rowindex;        Currentcolumn = E.columnindex; }///<summary>////////</summary>//<param name= "sender" in the right-click menu////></param&        Gt        <param name= "E" ></param> private void Modify Toolstripmenuitem_click (object sender, EventArgs e) {if (CurrentRow >-1 && currentcolumn >-1) {if (datagridview1.rows[c Urrentrow].

Not difficult, just a few lines of the whine, but let our code very human, said is the words, make this time, feel more than that a bunch of code to realize the joy of the function of the great.
