推荐答案

试试这个，



找到两个标签（即数量和价格） ）从您的gridview上的行数据绑定并乘以两个值并将其绑定在总列中，

Try this,

find the two labels(i.e, quantity and price) from your gridview on row data bound and multiply two values and bind it in total column,

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
    
        label lqty=(label)e.Row.findcontrol("Quantity_labelid_from Grid");
        label lprice=(label)e.Row.findcontrol("Price_id_from Grid");
        
        float total=float.parse(lqty.text)*float.parse(lprice.text);
        
        label ltot=(label)e.Row.findcontrol("Total_columnId");
        ltot.text=total.tostring();   
    }
}

已添加 pre 标签。

protected void grvList_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
    
                TextBox tqty = (TextBox)e.Row.FindControl("txtQuantity");
                TextBox tprice = (TextBox)e.Row.FindControl("txtPrice");

                float total = float.Parse(tqty.Text) * float.Parse(tprice.Text);

                TextBox ttot = (TextBox)e.Row.FindControl("txttotal");
                ttot.Text = total.ToString(); 
    }
}
