您好Yedhuvamshi，



尽管我理解您的问题，但您必须在Gridview的RowCreated事件中编写以下代码行： -

Hi Yedhuvams

As much I understand your problem, you have to write the following lines of code in RowCreated event of your Gridview:-

if (e.Row.RowType == DataControlRowType.DataRow)
            {
                e.Row.Attributes.Add("onclick", String.Format("EnableCheckBox({0});",e.Row.RowIndex));
            }

然后在你的Javascript代码中： -



function

And then in your Javascript code:-

function

EnableCheckBox(vRowIndex)
{
   // write your code to check the second check box
}

假设第一个复选框有一个id chk 。



然后在这里你可以做什么：

Suppose the first check box has an id chk.

then here what you could do:

chk.Attributes.Add("onclick","getindex(this.id)")

and then

function getindex(id)
{
 var index = document.getElementById(id).selectedIndex;
 }

请检查一下。
