在RowDataBound事件中添加您的代码.然后，您将获得单元格值.

在RowDataBound事件中添加以下代码.

声明存储行值的变量.

<数据类型> RowVal;

add your code at RowDataBound event. Then you get cell value.

In RowDataBound Event add following code.

declare a variable for store Row value.

<datatype> RowVal;

protected void CompanyGv1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
         RowVal = e.Row.Cells[1].Text.ToUpper();
    }
}

然后将此变量传递给您的代码.

And then pass this variable to your code.

protected void btncontact_Click(object sender, EventArgs e)
{
    Response.Redirect("~/Admin/Company/Contact.aspx?CompanyName=" + RowVal );
}

嘿

rowcommand事件将帮助您，将命令参数提供给控件(如选择按钮)，并获得当前行，这就是获取当前行的值.

如果您有不同的情况，请指定.

一切顺利.

hey

if you have different case please specify.

all the best..
