加载DataGridView时可以同时加载样式么？

[adolfaza]

C/S结构： 通过数据绑定功能绑定数据，然后通过循环该dataGridView查看符合条件的行进行颜色变化，为什么在窗体第一次打开的时候不能按照要求把不

同颜色的行显示出来，而是统一无样式的。
private void InitGrid(List<queryEntity> QueryEntity)
{
// dt = DataProvider.Instance().send_bill_Detail_list(QueryEntity);
dt = DataProvider.Instance().sendBill_DetailList(QueryEntity);

dt.DefaultView.Sort = " sprePlanNo desc";
dt = dt.DefaultView.ToTable();

gvList.Columns["id"].DataPropertyName = "spreid";
gvList.Columns["swipecardCount"].DataPropertyName = "swipecardCount";

gvList.Columns["lastszQty"].DataPropertyName = "lastszQty";


gvList.Columns["topno"].DataPropertyName = "spreMainNo";
gvList.Columns["no"].DataPropertyName = "sprePlanNo";
gvList.Columns["createdate"].DataPropertyName = "CreateDate";
gvList.Columns["ownername"].DataPropertyName = "fullname";

gvList.Columns["productname"].DataPropertyName = "proName";
gvList.Columns["sprenum"].DataPropertyName = "spreAmount";

//gvList.Columns["sendBoardnum"].DataPropertyName = "BoardName";
gvList.Columns["sendBoardnum"].DataPropertyName = "sendBoardNo";
gvList.Columns["sendTankNum"].DataPropertyName = "TankName";
gvList.Columns["dictunit"].DataPropertyName = "dictUnit";

//gvList.Columns["dicttype"].DataPropertyName = "typeName";
gvList.Columns["dicttype"].DataPropertyName = "dictType";

gvList.Columns["carno"].DataPropertyName = "carNo";
gvList.Columns["caruser"].DataPropertyName = "driveNo";

gvList.Columns["startDate"].DataPropertyName = "startDate";
gvList.Columns["endDate"].DataPropertyName = "endDate";
//gvList.Columns["chae"].DataPropertyName = "chae";


winformUtil.BindGridView(dt, gvList);


navigator1.DataBanding();

showcolor(ref gvList);
}


//显示不同颜色的函数

private void showcolor(ref DataGridView giv)
{
if (giv != null)
{
for (int i = 0; i < giv.Rows.Count; i++)
{
if (Convert.ToSingle(giv.Rows[i].Cells[1].Value) > 0)
{
giv.Rows[i].DefaultCellStyle.BackColor = Color.Gray;
}
}
}
}

结果只有点查询进行重载dataGridView时可以，而在最开始打开该窗体的时候不能显示要改变行的颜色，请问下这是什么问题啊？

换事件 DataSourceChanged

[adolfaza]

怎么换啊？

[sinitek123]

绑定数据 DataSourceChanged 判断该颜色程序放这里

[adolfaza]

通过这个方法同样不能加载这个初始化颜色的问题

[sinitek123]

for (int i = 0; i < giv.Rows.Count; i++)
{
if (Convert.ToSingle(giv.Rows[i].Cells[1].Value) > 0)
{
giv.Rows[i].DefaultCellStyle.BackColor = Color.Gray;
}
} 直接写在DataSourceChanged 应该可以的
