delete.cs:
delete.cs:
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Label lblProductid = GridView1.Rows[e.RowIndex].FindControl("lblProductid") as Label;
int prodcutid = Convert.ToInt32(lblProductid.Text);
query = "delete from attachment where ID= " + prodcutid + " ";
setConnectionString();
Message = EmpBal.binddeleteuserBAL(query, conString);
if (Message == "success")
{
Bind();
}
}
}
}
将按钮设为模板字段
Make a button as template field
<asp:templatefield xmlns:asp="#unknown">
<itemtemplate>
<asp:linkbutton id="lb1" runat="server" causesvalidation="false" onclientclick="return <b>confirm('Are You sure to delete this entry')</b>" text="Delete">CommandArgument='<%#Eval("id")%>' ></asp:linkbutton>
</itemtemplate>
</asp:templatefield>
并且gridview的行命令事件用作
and on row command event of gridview use as
protected void rowcmd(object sender, GridViewCommandEventArgs e)
{
try
{
Int32 id = Convert.ToInt32(e.CommandArgument);
string comm = "Delete from tblComments where id=@id";
SqlCommand cmd = new SqlCommand(comm, Db.GetConnection());
cmd.Parameters.AddWithValue("id", id);
cmd.ExecuteNonQuery();
GridView1.DataBind();
}
catch (Exception ex)
{
}
}
}
