Gridview行删除中的问题 [英] Problem in Gridview Row Deletion

问题描述

大家好，

我正在尝试模拟购物车功能.我的可用产品显示在Products_Gridview中，该视图具有AddTOCart按钮.当按下此按钮时，它将使用较少的Product表中的列构建一个DataTable，并将其绑定到另一个gridview(Cart_Gridview).我也将此数据表存储在viewstate中，以供以后绑定.

现在的问题是我希望在Cart_GridView的每一行中都具有一个Remove按钮，该按钮可以从Cart_Gridview中删除相对行.我已经尝试了很多，但是无法从Cart_Gridview删除行.我还尝试从绑定了购物车gridview的数据表中删除行，但是在Cart_GridView_RowDeleting和Cart_GridView_RowCommad事件中，它在DataTable中显示了0行.

任何帮助将不胜感激.

在此先感谢

Hi all,

I am trying to simulate a shopping cart functionality. My available products are displaying in a Products_Gridview, which have a AddTOCart button. When this button is pressed it builds a DataTable with fewer columns from Product table and binds it to another gridview (Cart_Gridview). I store this datatable in viewstate also for later binding also.

Now the problem is that I want a Remove button in each row of Cart_GridView which could delete relative row from Cart_Gridview. I have tried a lot but could''nt delete row from Cart_Gridview. I also tried to delete row from data table from which cart gridview is bind but it shows 0 row in DataTable in Cart_GridView_RowDeleting and Cart_GridView_RowCommad Events.

any help will be greatly appreciated.

Thanks in advance

感谢亲爱的回复.

我找到了解决方案.实际上，我忘记了从RowCommand的ViewState中获取Cart_GridView.终于我做到了.

感谢您审核...

Thanks for replying dear.

I found the solution. Actually I was forgetting to take Cart_GridView from ViewState in RowCommand. Finally I did it.

Thanks for reviewing...
