C# – Using GridView inside UpdatePanel

asp.netasp.net-ajaxcupdatepanel

I have an Updatepanel and Gridview inside it.

<asp:UpdatePanel ID="uplPanel" UpdateMode="Conditional" runat="server" OnLoad="uplPanel_Load">
<ContentTemplate>
 <asp:GridView ID="gvPrList" runat="server" AutoGenerateColumns="false" AllowPaging="false"
       AllowSorting="false" CssClass="list-table" HeaderStyle-CssClass="header">
       <Columns>
     <ItemTemplate>
               <asp:Button ID="btnEdit" runat="server" Text="Edit" CssClass="button save" OnCommand="onPrItemCmd"
                   CommandName="editRow" CommandArgument='<%#Bind("ID") %>' Style="width: 80px" />
               <asp:Button ID="btnDelete" runat="server" Text="Delete" CssClass="button save" OnCommand="onPrItemCmd"
                   CommandName="deleteRow" CommandArgument='<%#Bind("ID") %>' Style="width: 80px" />
           </ItemTemplate>
       </asp:TemplateField>
   </Columns>

When I click on my buttons inside the Griview, it does not fire the events.
Any idea?

You need to add OnCommand event of GridView and then handle that inside that event like this:

OnRowCommand="gvPrList_OnRowCommand"

or alternatively add a click event for the individual button and then handle in the code behind file:

<asp:Button ID="btnEdit" runat="server" OnClick="btnEdit_Click" Text="Edit" CssClass="button save"
                   OnCommand="onPrItemCmd" CommandName="editRow" CommandArgument='<%#Bind("ID") %>' Style="width: 80px" />

C# – Should ‘using’ directives be inside or outside the namespace

There is actually a (subtle) difference between the two. Imagine you have the following code in File1.cs:

// File1.cs
using System;
namespace Outer.Inner
{
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now imagine that someone adds another file (File2.cs) to the project that looks like this:

// File2.cs
namespace Outer
{
    class Math
    {
    }
}

The compiler searches Outer before looking at those using directives outside the namespace, so it finds Outer.Math instead of System.Math. Unfortunately (or perhaps fortunately?), Outer.Math has no PI member, so File1 is now broken.

This changes if you put the using inside your namespace declaration, as follows:

// File1b.cs
namespace Outer.Inner
{
    using System;
    class Foo
    {
        static void Bar()
        {
            double d = Math.PI;
        }
    }
}

Now the compiler searches System before searching Outer, finds System.Math, and all is well.

Some would argue that Math might be a bad name for a user-defined class, since there's already one in System; the point here is just that there is a difference, and it affects the maintainability of your code.

It's also interesting to note what happens if Foo is in namespace Outer, rather than Outer.Inner. In that case, adding Outer.Math in File2 breaks File1 regardless of where the using goes. This implies that the compiler searches the innermost enclosing namespace before it looks at any using directive.
