i uploaded file in gridview and now i want to view these files i.e when any user click view button then this documnet view in broswer or open in other tab
<asp:GridView ID="GridView1" runat="server" CellPadding="4" ForeColor="#333333"
GridLines="None" AutoGenerateColumns="false" EmptyDataText="no files uploaded">
<asp:HyperLink runat="server" ID="lnkButton" Text="View File" />
<RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
<FooterStyle BackColor="#5D7B9D" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#284775" ForeColor="White" HorizontalAlign="Center" />

if (FileUploadControl.HasFile)
{
string strPath = Request.PhysicalApplicationPath + "~/DocFiles/" + FileUploadControl.FileName;
FileUploadControl.SaveAs(strPath);
lnkButton.NavigateUrl = "~/DocFiles/" + FileUploadControl.FileName;
}
}

当前上下文中不存在'lnkButton'这个名字
我称之为grdiview中的链接按钮（上面的网格代码）

"The name 'lnkButton' does not exist in the current context "
where as i call the link button in grdiview (gridvie code above)

推荐答案
你可以做类似的事情这个：
You can do something like this:
foreach(GridViewRow row in GridView1.Rows)
{
LinkButton lb = (LinkButton) row.Cells[1].FindControl("id of button"); // Just change the index of Cells based on your requirements
}
