I have a ListView nested inside the column of a GridView, which looks something like this: 

```
<asp:panel id="myPanel" Runat="server" EnableViewState="False">
    <asp:GridView id="myDescription" AutoGenerateColumns="False" Width="100%" runat="server"
         OnRowCommand="my_RowCommand"  OnRowDataBound="GetDataForListView" EnableViewState="False">
        <Columns>
            <asp:BoundField DataField="id" HeaderText="ID">
                <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                <ItemStyle HorizontalAlign="Center"></ItemStyle>
            </asp:BoundField>
            <asp:BoundField DataField="data1" HeaderText="Thing 1">
                <HeaderStyle   HorizontalAlign="Center"></HeaderStyle>
                <ItemStyle   HorizontalAlign="Center"></ItemStyle>
            </asp:BoundField>
            <asp:BoundField DataField="data2" HeaderText="Thing2">
                <HeaderStyle   HorizontalAlign="Center"></HeaderStyle>
                <ItemStyle   HorizontalAlign="Center"></ItemStyle>
            </asp:BoundField>
            <asp:BoundField DataField="data3" HeaderText="Thing3">
                <HeaderStyle   HorizontalAlign="Center"></HeaderStyle>
                <ItemStyle   HorizontalAlign="Center"></ItemStyle>
            </asp:BoundField>
            <asp:TemplateField SortExpression="id">
                <ItemTemplate> 
                    <asp:HyperLink id="hlView"  runat="server"  NavigateUrl="...">View</asp:HyperLink>
                </ItemTemplate>
            </asp:TemplateField>
            <asp:TemplateField HeaderText="Column to contain my list of things">
                <HeaderStyle HorizontalAlign="Center"></HeaderStyle>
                <ItemStyle HorizontalAlign="Center"></ItemStyle>
                <ItemTemplate>
                    <% /* This is my list view: */ %>
                    <asp:ListView ID="myListView" runat="server" OnItemCommand="DoSomething" EnableViewState="False">
                        <ItemTemplate>
                            <asp:LinkButton ID="lbAttachment" Runat="Server" Text='<%# Eval("FILE_NAME") %>'
                                CommandName='<%# Eval("ROW_NUM") %>' CausesValidation="False" > 
                            </asp:LinkButton><br/>
                        </ItemTemplate>
                    </asp:ListView>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>
</asp:panel>

```

The data is successfully binding, but the OnCommand event is not being fired on clicking the LinkButton (nor is any other event for the LinkButton, such as an OnClick event). 

The rendered HTML for the link button shows that on clicking it, the page is performing a postback: `javascript:__doPostBack('...','')`

This means it is going back into my 'Page\_Load' and refreshing the contents of the page - the grid view is binded here. 

I can stop it from performing a postback by adding this attribute to the LinkButton: 

```
OnClientClick="return false;"

```

But this only stops the postback from occurring, the OnCommand event still doesn't fire. 

Any ideas? 

The event signature in the code-behind is: 

```
protected void DoSomething(object sender, CommandEventArgs e) { ... }

```

I have also tried using an OnItemCommand event on the ListView control with this event signature, but similarly the event is not invoked: 

```
protected void DoSomething(object sender, ListViewCommandEventArgs e)

```

The OnRowdataBound event on the parent GridView is successfully invoked, it's only the nested ListView that fails to invoke its event. 

The code I have shown is for the 2nd GridView on the page, there is another one too, and it is this one which gets binded on the Page\_Load event. The Page Load event has a sequence of events as follows, where the 1st GridView (which we'll call GridView1) is bound: 

**Page\_Load**

Data for GridView is retrieved from database

* Data is assigned to a 'DataView' object and assigned to the GridView1 DataSource property.
* GridView1.DataBind() is invoked
* Miscellaneous conditional logic which removes certain columns from GridView1
* An OnClick attribute is added to each row.

So actually, the Page\_Load binds the first GridView. The 2nd GridView is the one which contains the ListView which I am having a problem with. This 2nd GridView (the code of which is at the top of the post) is populated on the 'OnRowCommand' event of the 1st GridView, and has a sequence like this:

**GetDataForListView**

Get data from database

* Assign the DataSet containing the data to the DataSource property of the 2nd GridView
* Call the DataBind() method

Then, as you can see from the code I posted at the top, I have the OnRowDataBound event which fails to invoke its event in the code-behind.
