Question

一个复选框控制gridView里的复选框是否全选，同时要改变一下选中了的行的颜色怎么实现？(全选效果已实现)
 protected void chkAllUser_CheckedChanged(object sender, EventArgs e)
    {
        if (chkAllUser.Checked)
        {
            foreach (GridViewRow row in grvUser.Rows)
            {
                CheckBox userbox = row.FindControl("chkUser") as CheckBox;
                userbox.Checked = true;
                row.BackColor = Color.FromName("#F5A300");
            }        }
        else
        {
            foreach (GridViewRow row in grvUser.Rows)
            {
                CheckBox userbox = row.FindControl("chkUser") as CheckBox;
                userbox.Checked = false;
            }
        }
    }

Answer 1

protected void chkAllUser_CheckedChanged(object sender, EventArgs e) 
    { 
        if (chkAllUser.Checked) 
        { 
            foreach (GridViewRow row in grvUser.Rows) 
            { 
                CheckBox userbox = row.FindControl("chkUser") as CheckBox; 
                userbox.Checked = true; 
                row.BackColor = Color.FromName("#F5A300"); 要在dataBound事件里才起作用，所以改变颜色怎么完成？
            }         } 
        else 
        { 
            foreach (GridViewRow row in grvUser.Rows) 
            { 
                CheckBox userbox = row.FindControl("chkUser") as CheckBox; 
                userbox.Checked = false; 
            } 
        } 
    }

Answer 2

在GridView的RowDataBound输入代码
假定CheckBox在第0列,id是CheckBox1
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox myC = (CheckBox)e.Row.Cells[0].FindControl("CheckBox1");
e.Row.Attributes.Add("id", "tr" + e.Row.RowIndex.ToString());
myC.Attributes.Add("onclick", "ChangeColor(" + myC.ClientID + ",tr" + e.Row.RowIndex.ToString() + ");");
}
}js代码:
<script type="text/javascript">
function ChangeColor(obj,tr)
        { 
            if(obj.checked) 
            {
                tr.style.backgroundColor='#adff2f'; 
            }
            else 
            {
                tr.style.backgroundColor='#f5F5F5'; 
            }
        }
</script>
