推荐答案

在gridview_rowdatabound事件中尝试此操作.
< pre lang ="c#">
如果(e.Row.RowType == DataControlRowType.DataRow)
{
字符串strOperation =(((DataRowView)e.Row.DataItem)["Operation"].ToString();
//查找从网格中删除的行并计算总金额
如果(strOperation =="2")
{
e.Row.Visible = false;
}
}
</pre>

In gridview_rowdatabound event try this.. I am sure this will help you.

<pre lang="c#">
if (e.Row.RowType == DataControlRowType.DataRow)
{
string strOperation = ((DataRowView)e.Row.DataItem)["Operation"].ToString();
//Finding the rows which is deleted from the grid and calculating the total amounts
if (strOperation == "2")
{
e.Row.Visible = false;
}
}
</pre>
