CheckBox SelectAll / DeselectAll [英] CheckBox SelectAll / DeselectAll

问题描述

我的网格看起来像这样..

My Grid is look like this..

col0         col1
checkbox     123
checkbox     234
empty row
checkbox     12

现在我尝试做的是我想选择所有复选框'和DeselectAll怎么做...





我正在尝试以下方式...

now what i''m try to do is i want to select All checkBox''s and DeselectAll how to do...


i''m trying in the following way...

function CheckAll(oCheckbox) {
    var gdDocument = document.getElementById("<%=gdDocument.ClientID %>");

    for (i = 1; i < gdDocument.rows.length; i++) {
        gdDocument.rows[i].cells[0].getElementsByTagName("INPUT")[0].checked = oCheckbox.checked;
     }

}

<HeaderTemplate>
     <input id="chkSelect" type="checkbox" onclick="CheckAll(this)" runat="server" />
 </HeaderTemplate>
 <ItemTemplate>
     <asp:CheckBox ID="chkSelect" runat="server"  />
 </ItemTemplate>

但是这个代码适用于每个&每个人都有一条记录，这段代码工作正常，但每当行复选框不可见（false）。在那种情况下，从那里开始，没有选中复选框'。



任何人都可以帮我解决这个问题......

推荐答案

尝试以下代码，它对我来说工作正常

try the following code, its working fine for me

protected void chekSelectALL_CheckedChanged(object sender, EventArgs e)
    {
        CheckBox chkA = GridView1.HeaderRow.FindControl("chekSelectALL") as CheckBox;
        foreach (GridViewRow gv in GridView1.Rows)
        {
            CheckBox chkS = gv.FindControl("chekSelect") as CheckBox;
            if (chkA.Checked)
            {
                chkS.Checked = true;
            }
            else
            {
                chkS.Checked = false;
            }
        }
    }
