Above is my GridView code, I have about 8 other columns too but I removed them.
Even though I have the row Editing method to catch any edits, my page keeps on throwing the error:

You can fix it by adding an empty event
protected void grd_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
}
developernaderJust change the "CommandName" property of the "Edit" or "Delete" button from "Edit" to "Editttt" "Delete" to "Deleteee" (or something else which is relevent to you but make sure it is not "Edit" or "Delete"). It will works fine.
Ramil MammadovFrom your gridview Code remove this
AutoGenerateEditButton="True"
This is not required.as you have taken the Custom Template in creating your gridview.I guess the gridview is more simple than what you have done.
<asp:GridView ID="gvBuildList" runat="server" AutoGenerateColumns="False" AllowPaging="True" OnRowEditing="gvBuildList_RowEditing">
<AlternatingRowStyle CssClass="alt"></AlternatingRowStyle>
<Columns>
<asp:BoundField DataField="ProductName" HeaderText="Product Name" SortExpression="ProductName" />
<asp:BoundField DataField="Platform" HeaderText="Platform" SortExpression="Platform" />
<asp:BoundField DataField="BuildDate" HeaderText="Build Date" SortExpression="BuildDate" />
<asp:BoundField DataField="Publisher" HeaderText="Publisher" SortExpression="Publisher" />
<asp:BoundField DataField="VersionNumber" HeaderText="Version #" SortExpression="VersionNumber" />
<asp:BoundField DataField="FileName" HeaderText="Build" SortExpression="FileName" />
<asp:BoundField DataField="ReleaseFileName" HeaderText="Release Notes" SortExpression="ReleaseFileName" />
<asp:BoundField DataField="Comments" HeaderText="Comments" SortExpression="Comments" />
<asp:ButtonField ButtonType="Image" CommandName="Edit" HeaderText="Edit"
ImageUrl="Images/hard-drive-download.png" ShowHeader="True" Text="Edit" />
If you want to use Custom Template in gridview then you have to Use Command Name property. as Gridview will not find the Edit event.
Replace your gridview with this one and your code will work.
MoizReBuild you application [Compile your code] and your error will be no more.
As you have written code in Code behind but not compiled. so gridview is not getting the Row_editing event.
Goto -> Build -> Rebuild Solution
MoizSo, after trying out a few different things, the simplest solution.
I had my gridview binding in pageload. That was what was causing this issue. All I had to do was move the GV binding to
if (!Page.IsPostBack)
{
getBuildData();
}
Within the Page_Load Method
ArjaaAineToday, I also faced this problem. After one hour, I noticed that there are two events in Gridview events tab. Events names should be noted:
RowUpdating Event
RowUpdate Event
Make sure you are using right event for your code.

MogsdadThe GridView 'GridView1' fired event RowEditing which wasn't handled
Just change CommandName="Edit" to others like CommandName="RowEdit"
