Hello Developers
I'm stuck on one problem in that I've a Parent GridView and Child Grid View And Child GridView has multiple rows and single column in the row I'm storing the Dropdown and next to dropdown I've a LinkButton for Download the file which is shown in dropdownlist.
What I've to do is When user Click on Down button I've to download the file whatever user selected from DropDownList So When I try to click on Download I don't know how to find the dropdownlist of child GridView

What I have tried:

<asp:gridview id="ParentGV" runat="server">
<asp:gridview id="ChildGV" runat="server">
<asp:dropdownlist id="FileList" runat="server">
<asp:listitem value="a.jpg" text="a.jpg">
<asp:listitem value="b.jpg" text="b.jpg">
<asp:listitem value="c.jpg" text="c.jpg">

<asp:linkbutton id="lnkDownloadFile" text="Download" onclick="DownLoad_click" runat="server">

Assuming the link button and list are in the same grid row, try:

C#

protected void Download_click(object sender, EventArgs e)
{
    var button = (Control)sender;
    var list = (DropDownList)button.NamingContainer.FindControl("FileList");
    string file = list.SelectedValue;
    ...
}
