<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. 然后在gridview RowDeleting Action中，在该方法后面的代码中，执行您的逻辑，它将为您拉入行。
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

Actual Question Was "I want to know how to get the event of the button so that button will work only for the specific row?" 实际问题是“我想知道如何获取按钮的事件，以便该按钮仅适用于特定行吗？”

{
if (!IsPostBack)
{
SqlConnection con = new SqlConnection("Data Source=HAMMADMAQBOOL;Initial Catalog=ModulesDB;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=False");
con.Open();
SqlDataAdapter da = new SqlDataAdapter("Select * From GVDemo", con);
DataSet ds = new DataSet();
da.Fill(ds);
GridView1.DataSource = ds.Tables[0];
GridView1.DataBind();
}
}
protected void Button1_Click(object sender, EventArgs e)
{
Button btn = (Button)sender;
GridViewRow gvr = (GridViewRow)btn.NamingContainer;
if (gvr.RowType == DataControlRowType.DataRow)
{
string Namme = (gvr.FindControl("LabelName") as Label).Text;
//Write Query here to Delete Data. . .
//Call Functon Here to Delete the Image From Folder. . .
}
}
}
