无法从gridview中删除特定行 [英] Unable to delete specific row from gridview

问题描述

我在删除gridview中的特定行时遇到问题。



这是错误消息：



输入字符串的格式不正确


此特定行的




int shoppingCartID = Convert.ToInt32（delCart.CommandArgument）;



任何想法为什么？



除此之外， delCart.CommandArgument的值是userID和shoppingCartID：



int userID = Convert.ToInt32（Session [userID] =3）;

int shoppingCartID = Convert.ToInt32（delCart.CommandArgument）;

del.DeleteSCitems（userID，shoppingCartID）;

hi i have issues deleting a specific row in the gridview.

this is the error message:

Input string is not in a correct format

for this particular line

int shoppingCartID = Convert.ToInt32(delCart.CommandArgument);

any idea why?

in addition to this, the value for delCart.CommandArgument is userID and shoppingCartID :

int userID = Convert.ToInt32(Session["userID"] = "3");
int shoppingCartID = Convert.ToInt32(delCart.CommandArgument);
del.DeleteSCitems(userID, shoppingCartID);

推荐答案

嗨


如果您使用的是GridView_RowCommand：

Hi
Follow the below one, If you are using GridView_RowCommand:

GridViewRow gRow = (GridViewRow)(((ImageButton)e.CommandSource).NamingContainer);
int RowIndex = gRow .RowIndex; 

使用行索引获取所选行ID并删除记录。



点击Delete boutton，它在项目模板内：

Use the row index and get the selected row id and delete the record.

Click on Delete boutton and it is inside item template:

GridViewRow gRow = (GridViewRow)((ImageButton)(sender)).NamingContainer;
string strId = ((HiddenField)gRow.FindControl("hdnId")).Value;

使用strId并删除。



问候

遗嘱

use the strId and delete.
