C# DataGridView绑定后单元格内显示为红叉

[tanglihui520]

先一个一个读取数据没读取到一行就调用刷新的DataGridView
调用刷新，获取的是网页的节点数据需要一点时间每读取一次就循环一次次数不定
Thread test = new Thread(new ThreadStart(RefeData));
test.Start();
//刷新方法
private void RefeData()
{
lock (ds)
{
string sql = string.Format("SELECT id,ranking,name,wangw,buy,week,time,outtime,shop FROM taodata");
try
{
if (ds.Tables.Count > 0)
{
ds.Tables.Clear();
}
ds = DbHelperSQLite.Query(sql);
bindingSource.DataSource = ds.Tables["ds"];
dgvdata.DataSource = bindingSource;
}
catch (Exception ex)
{

}
}
}

跨线程操作控件用Invoke

        private void RefeData()
        {
            lock (ds)
            {
                string sql = string.Format("SELECT id,ranking,name,wangw,buy,week,time,outtime,shop FROM taodata");
                try
                {
                    if (ds.Tables.Count > 0)
                    {
                        ds.Tables.Clear();
                    }
                    ds = DbHelperSQLite.Query(sql);

                    this.Invoke(new MethodInvoker(() =>
                    {
                        this.bindingSource.DataSource = ds.Tables["ds"];
                        this.dgvdata.DataSource = bindingSource;
                    }));
                }
                catch (Exception ex)
                {

                }
            }
        }

因為你用了.clear把整了結構都給清除了，如果只是單純清除數據就要把對象改為rows
