           }
       }

 protected void grdLocation_RowDeleting(object sender, GridViewDeleteEventArgs e)
       {
           Locations location = new Locations();
           location.LocationID = Convert.ToInt32(grdLocation.DataKeys[e.RowIndex].Value.ToString());
           location.Delete();
           bindgrdLocation();

       }

推荐答案

在grdLocation_RowDeleting()事件上执行删除操作后，再次调用网格绑定方法"bindgrdLocation"来绑定网格

Hi,

call the grid bind method "bindgrdLocation" again to bind the grid after the delete operation is performed on grdLocation_RowDeleting() event

您是否传递了要删除的行的索引?

Gv1.Deleterow(e.RowIndex);
Gvi.DataBind();

Are you passing the index of the row to be deleted??

Gv1.Deleterow(e.RowIndex);
Gvi.DataBind();
