<Columns> 
<asp:TemplateField HeaderText="Sl. No" ItemStyle-CssClass="col-md-1 col-sm-1"> 
<ItemTemplate> 
<%# Container.DataItemIndex + 1 %> 
</ItemTemplate> 

<ItemStyle CssClass="col-md-1 col-sm-1"></ItemStyle> 
</asp:TemplateField> 
<asp:TemplateField HeaderText="Health ID" ItemStyle-CssClass="col-md-1 col-sm-1" ItemStyle-HorizontalAlign="Center"> 
<ItemTemplate> 
<asp:Label ID="healthid" runat="server" Text='<%#Eval("Health_ID") %>'></asp:Label> 
</ItemTemplate> 

<ItemStyle HorizontalAlign="Center" CssClass="col-md-1 col-sm-1"></ItemStyle> 
</asp:TemplateField> 
<asp:TemplateField HeaderText="Name" ItemStyle-CssClass="col-md-1 col-sm-1" ItemStyle-HorizontalAlign="Center"> 
<ItemTemplate> 
<asp:Label ID="Name" runat="server" Text='<%#Eval("Health_Comment_Name") %>'></asp:Label> 
</ItemTemplate> 

<ItemStyle HorizontalAlign="Center" CssClass="col-md-1 col-sm-1"></ItemStyle> 
</asp:TemplateField> 
<asp:TemplateField HeaderText="Email" ItemStyle-CssClass="col-md-2 col-sm-2" ItemStyle-HorizontalAlign="Center">

</asp:TemplateField> 
<asp:TemplateField HeaderText="Comments" ItemStyle-CssClass="col-md-3 col-sm-3" ItemStyle-HorizontalAlign="Center"> 
<ItemTemplate> 
<asp:Label ID="lblRemark" runat="server" Text='<%# Eval("Health_Comment_Message").ToString().Length > 100? (Eval("Health_Comment_Message") as string).Substring(0,100) + " ..." : Eval("Health_Comment_Message") %>'ToolTip='<%# Eval("Health_Comment_Message") %> '> </asp:Label> 
</ItemTemplate> 

<ItemStyle HorizontalAlign="Center" CssClass="col-md-3 col-sm-3"></ItemStyle> 
</asp:TemplateField> 
<asp:TemplateField HeaderText="Status" ItemStyle-CssClass="col-md-1 col-sm-1" ItemStyle-HorizontalAlign="Center">

<div class="pull-left rpaddingdivsmall1"><a href="javascript:void(0)" data-toggle="tooltip" title="" class="btn btn-xs btn-success" data-original-title="View" onClick="doctordetailsshowdiv()"><i class="fa fa-eye"></i></a>/</div> 
<div class="profile_right_side_eidt pull-left"> 
<div class="btn-group btn-toggle"> 
<asp:LinkButton ID="accept" CssClass="btn btn-xs btn-inactive" CommandName="Accept" runat="server" style="padding:1px 2px;" Text="Accept" OnClick="accept_click"></asp:LinkButton> 
<asp:LinkButton ID="reject" runat="server" Text="Reject" CommandName="Reject" 
CssClass="btn btn-xs btn-success active" style="padding:1px 2px;" 
onclick="reject_Click" ></asp:LinkButton> 
</div> 
</div> 
<div class="clearfix"></div> 
</ItemTemplate> 

<ItemStyle CssClass="col-md-2 col-sm-2"></ItemStyle> 
</asp:TemplateField> 
</Columns> 
</asp:GridView> 

在這裏，我需要在用戶點擊任何的LinkBut​​ton（i.e. accept/Reject）相應的按鈕背景色將會改變，並且點擊事件裏面我需要的DataKeyNames value.Please幫我。

您可以通過CommandArgument單擊按鈕時，命令參數將所需值傳遞給後端。它可以在GridViewName_ItemCommand()事件通過e.CommandArgument

訪問，你可以給這樣也：

CommandArgument='<%#Eval("CustomerID")%>' 

要更改顏色點擊就可以使用，如：

Protected Void GridViewName_ItemCommand(Object sender, DataGridCommandEventArgs e) 
{ 
if(e.CommandName=="") 
    { 
    LinkButton lnkButton=(LinkButton)e.CommandSource 
    lnkButton.ForeColor = System.Drawing.Color.Red; 
    //Do any additional operation if needed on link button click 
    } 
}
