您好b $ b

下面是实现您功能的粗略代码

Hi
Below is rough code that implements your functionality

function ToggleTextBox(checkid,textid) {
            var checkBox = document.getElementById(checkid);
            if (checkBox.checked)
            {
                document.getElementById(textid).style.visibility = 'visible';
            }
            else
            {
                document.getElementById(textid).style.visibility = 'hidden';
            }
        }

网格视图定义

Grid View Definition

<asp:gridview runat="server" id="grid" onrowdatabound="RowDataBoundEvent" xmlns:asp="#unknown">
    <columns>
    <asp:templatefield headertext="Check">
    <itemtemplate>
        <asp:checkbox runat="server" id="cbSelect" checked="false" />
    </itemtemplate>
    </asp:templatefield>
    <asp:templatefield headertext="B1">
    <itemtemplate>
        <asp:textbox id="textBox" runat="server"></asp:textbox>
    </itemtemplate></asp:templatefield>
    </columns>
    </asp:gridview>
