Get selected index from gridview with jquery

All i want is to get the selected index (or selectedvalue or se开发者_运维百科lectedDataKey) of a gridview with jquery so i can use jquery ajax to load its data with that ID as parameter.

How can i get it with jquery?

Thank you.

Why would you want that?

Set SelectedRowStyle="myselection".
Now place a label in GridView in any existing TemplateField.
(Dont create any new asp:TemplateField because it will add a new column)

<asp:Label ID="HiddenLabel" runat="server" 
        CssClass="myindex"
        Text='<%# Container.DisplayIndex %>'
        style="display:none;"/>

Now retrieve the selected row index like this.

var selectedIndex = -1;
if($(".myselection").length){
    selectedIndex  = $(".myselection .myindex").html() - 0;
}

Update:

Multiple GridViews? You could still do that. Give each GridView a separate CssClass. CssClass="grid1"

var selectedIndex = -1;
if($(".grid1 .myselection").length){
    selectedIndex  = $(".grid1 .myselection .myindex").html() - 0;
}

I do not know of any simpler way. Sorry.
