dev GridControl中的GridView怎麽實現批量刪除、修改GridView表中的任意數據後保存。求大神解決

批量刪除好解決,選中GridView右上角的編輯添加模板列，選中ItemTemplate在裏面拉壹個復選框控件然後就是判斷復選框是否是選中狀態如果是循環刪除選中的數據列。修改的話就點編輯列在可用字段裏有壹個CommandField列點擊他展開編輯，更新，取消這壹行就點擊添加至於編輯更新取消這個有點兒麻煩意識說不清，我就直接給妳貼代碼了 #region 編輯事件

protected void gvBooks_RowEditing(object sender, GridViewEditEventArgs e)

{

//設定選中行

gvBooks.EditIndex = e.NewEditIndex;

//重新綁定數據

HRDataBind();

//獲取選中行的下拉框控件

DropDownList ddl = (DropDownList)gvBooks.Rows[e.NewEditIndex].FindControl("ddlCate");

//查詢綁定數據

ddl.DataSource = cm.GetAllCategories();

ddl.DataTextField = "Name";

ddl.DataValueField = "Id";

ddl.DataBind();

//查詢隱藏列

HiddenField hf = (HiddenField)gvBooks.Rows[e.NewEditIndex].FindControl("hfCateId");

ddl.SelectedValue = hf.Value;

}

#endregion

#region 取消編輯

protected void gvBooks_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)

{

//GV恢復正常狀態

gvBooks.EditIndex = -1;

//重新綁定數據

HRDataBind(); ;

}

#endregion

#region 更新

protected void gvBooks_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

//獲取圖書Id

int id = Convert.ToInt32(gvBooks.DataKeys[e.RowIndex].Value);

//圖書名

string title = ((TextBox)gvBooks.Rows[e.RowIndex].FindControl("txtTitle")).Text;

//作者

string author = ((TextBox)gvBooks.Rows[e.RowIndex].FindControl("txtAuthor")).Text;

//類別id

DropDownList ddl = (DropDownList)gvBooks.Rows[e.RowIndex].FindControl("ddlCate");

int cateId = Convert.ToInt32(ddl.SelectedValue);

//根據Id查詢book

Books book = bm.QueryBookById(id);

book.Title = title;

book.Author = author;

book.Categories = new Categories() { Id = cateId };

//更新

bm.UpdateBook(book);

//更新完成恢復正常狀態

gvBooks.EditIndex = -1;

HRDataBind();

}

#endregion

#region 刪除

protected void gvBooks_RowDeleting(object sender, GridViewDeleteEventArgs e)

{

//獲取id

int id = Convert.ToInt32(gvBooks.DataKeys[e.RowIndex].Value);

//刪除

bm.DeleteBook(id);

//重新綁定

HRDataBind();

}

#endregion
