gridview使用技巧

    
    1、CheckBox模板选择事件
    //多选业务员事件
    protected void cbSelect_CheckedChanged(object sender, EventArgs e)
    {
        string pNames=lblPersonNames.Text;
        personList = new List<string>(pNames.Split(new string[]{","},StringSplitOptions.RemoveEmptyEntries));

        CheckBox cbSelect = (CheckBox)sender;
        DataControlFieldCell dcf = (DataControlFieldCell)cbSelect.Parent;  //父对象Cell

        GridViewRow gr = (GridViewRow)dcf.Parent;     //父对象row
        if (cbSelect.Checked)
        {
            personList.Add(gr.Cells[0].Text);
        }
        else
        { 
            personList.Remove(gr.Cells[0].Text);
        }
        lblPersonNames.Text = string.Join(",", personList.ToArray());
    }

    
    2、行绑定事件
    protected void gvPerson_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            string pNames = lblPersonNames.Text;
            personList = new List<string>(pNames.Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries));

            string personName=e.Row.Cells[0].Text;
            if (personList.Contains(personName))
            {
                CheckBox cbSelect=(CheckBox)e.Row.FindControl("cbSelect");
                cbSelect.Checked = true;
            }
        }
    }

 

   附加：javascript数组扩展方法
        Array.prototype.remove = function(val) {
            var index = this.indexOf(val);
            if (index > -1) {
                this.splice(index, 1);
            }
        }
