gridview任務(wù)——〉編輯列 添加一個(gè)commandField，設(shè)置showDeleteBotton和showEditBotton為true gridview的數(shù)據(jù)邦定函數(shù)

????void data_bind()
????{

????????DataSet ds = new DataSet();
????????String sqlstr123 = "select 序號(hào),咨詢問(wèn)題,反饋信息 from 咨詢表";

????????ds = connectDB.dataSet(sqlstr123);

????????GridView1.DataSource = ds.Tables[0].DefaultView;

????????GridView1.DataBind();
????????//conn1.Dispose();
????????ds.Dispose();
????}

點(diǎn)擊編輯時(shí)使選定的datarow處于編輯狀態(tài)

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
????{
????????????GridView1.EditIndex = e.NewEditIndex;
????????????data_bind();

????}

當(dāng)“編輯”文字變成“更新”時(shí)，單擊更新

?protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
????{

????????GridView1.EditIndex = -1;
????????TextBox txt =(TextBox) GridView1.Rows[e.RowIndex].Cells[2].Controls[0];
????????TextBox txt1 = (TextBox)GridView1.Rows[e.RowIndex].Cells[3].Controls[0];
????????String sqlstr = "update 咨詢表 set 咨詢問(wèn)題='" + txt.Text + "' , 反饋信息='" + txt1.Text + "'";
????????connectDB.ExecuteUpdate(sqlstr);
????????data_bind();
}

?

取消編輯

protected void GridView1_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
????{
????????GridView1.EditIndex = -1;
????????data_bind();
????}
