DEV Gridcontrol 查詢得到0條記錄時顯示自定義的字符提示/顯示
private void gridView_CustomDrawEmptyForeground(object sender, DevExpress.XtraGrid.Views.Base.CustomDrawEventArgs e)
{
if (this.judge_ds(dsDt))
{
string str = "沒有查詢到你所想要的數據!";
Font f = new Font("宋體", 10, FontStyle.Bold);
Rectangle r = new Rectangle(e.Bounds.Top + 25, e.Bounds.Left + 25, e.Bounds.Right - 25, e.Bounds.Height - 25);
e.Graphics.DrawString(str, f, Brushes.Black, r);
}
}
#region 判斷ds是否為空
private bool judge_ds(DataSet ds)
{
bool flag = false;
if (ds == null||ds.Tables.Count == 0||(ds.Tables.Count == 1 && ds.Tables[0].Rows.Count == 0))
{
flag = true;
}
return flag;
}
#endregion
小注:
如果顯示提示信息的位置不對可以通過調整,Rectangle函數後麵的數字來實現。
