Button in every Row of Gridview C# Asp.NET
Question
In ASP.NET using C# I want to put a button in every row of Gridview which should perform two actions
Delete the Record of That Row.
Delete an image from folder related to that row.
I can perform the above operations but I want to know how to get the event of the button so that button will work only for the specific row?

<asp:GridView ID="GridView1" runat="server" OnRowDeleting="GridView1_RowDeleting">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Button ID="Button" Text="BUTTON" runat="server" CommandName="Delete" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
Then in the gridview RowDeleting Action,in the code behind method for that, do your logic, it will pull the row in for you.
protected void GridView1_RowDeleting(object sender, GridViewDeletedEventArgs e)
{
//ROW YOU ARE DELETING
int rowindex = e.RowIndex;
//Do your Delete Logic Here
}

按钮具有CommandArgument属性，可用于存储行ID，然后在带有代码的on click事件内的代码中获取该ID
string RowID = (sender as Button).CommandArgument
