如何使用C#中的DataGridView控件

Answer 1

1.先是：

C#中的DataGridView控件使用出错:No row can be added to a DataGridView control that does not have columns

2.后来就可以正常显示数据了：

相关代码：

//DataGridView init
           dgvSearchResult.ColumnCount = 13;

           //dgvSearchResult.Rows.Add();

           //(1)title
           dgvSearchResult.Columns[0].HeaderText = "Title";
           //(2)seller rating ( based on 1-100% format )
           dgvSearchResult.Columns[1].HeaderText = "Seller Rating";
           //(3)estimated delivery ( based on 24 hours - 7days format )
           dgvSearchResult.Columns[2].HeaderText = "Estimated Delivery";
           //(4)gig rating ( based on 1-100% )
           dgvSearchResult.Columns[3].HeaderText = "Gig Rating";
           //(5)orders in que ( based on 0-9999 format )
           dgvSearchResult.Columns[4].HeaderText = "Orders in Queue";
           //(6)level of the seller ( 1-3 )
           dgvSearchResult.Columns[5].HeaderText = "Seller Level";
           //(7)haz video ( yes or no )
           dgvSearchResult.Columns[6].HeaderText = "Has Video";
           //(8)express gigs (yes or no )
           dgvSearchResult.Columns[7].HeaderText = "Is Express Gig";
           //(9)country flag ( display county flag )
           dgvSearchResult.Columns[8].HeaderText = "Country Flag";
           //(10)+ve reviews and -ve reviews ( based on 1-9999 )
           dgvSearchResult.Columns[9].HeaderText = "Positive Reviews";
           dgvSearchResult.Columns[10].HeaderText = "Negative Reviews";
           //(11)top rated seller ( yes or no )
           dgvSearchResult.Columns[11].HeaderText = "Is Top Rated Seller";
           //(12)gig url
           dgvSearchResult.Columns[12].HeaderText = "Gig Url";

和

dgvSearchResult.Rows.Add(
       singleGigInfo.title,
       singleGigInfo.sellerRating,
       singleGigInfo.estimatedDelivery,
       singleGigInfo.gigRating,
       singleGigInfo.ordersInQueue,
       singleGigInfo.sellerLevel,
       singleGigInfo.hasVideo,
       singleGigInfo.isExpressGig,
       singleGigInfo.coutryFlag,
       singleGigInfo.positiveReviews,
       singleGigInfo.negativeReviews,
       singleGigInfo.isTopRatedSeller,
       singleGigInfo.gigUrl);
