1. 让列宽保持不变，当列特别多的时候出现滚动条 设置 View 中的OptionsView 中的 ColumnAutoWidth = False
2.使某一列出现如下拉框，复选框等效果：设置那一列的ColumnEidt
3.要对单元格的输入进行验证，使用gridview的ValidatingEditor事件
//输入验证
private void gridView1_ValidatingEditor(object sender, BaseContainerValidateEditorEventArgs e)
{
GridView gv = sender as GridView;
List<string> timeColns = new List<string> { "PEDGRNTM", "PEDREDTM", "MINGRNTM", "GRNEXTENDTM", "MAXGRN1TM",
"MAXGRN2TM", "FIXGRNTM"};
if (timeColns.Contains(gv.FocusedColumn.FieldName))
{
int inputValue;
if (!(int.TryParse(e.Value.ToString(), out inputValue) && inputValue >= 0 && inputValue <= 255))
{
e.Valid = false;
e.ErrorText = "必须是0到255的整数";
}
}
}4.要对单元格显示tooltip 需要先添加一个ToolTipController到窗口中，然后实现其GetActiveObjectInfo事件
//单元格显示tooltip
private void toolTipController1_GetActiveObjectInfo(object sender, DevExpress.Utils.ToolTipControllerGetActiveObjectInfoEventArgs e)
{
if (e.SelectedControl != gridControl1)
return;
ToolTipControlInfo info = null;
//Get the view at the current mouse position
GridView view = gridControl1.GetViewAt(e.ControlMousePosition) as GridView;
if (view == null) return;
//Get the view's element information that resides at the current position
GridHitInfo hitInfo = view.CalcHitInfo(e.ControlMousePosition);
if (hitInfo.HitTest == GridHitTest.RowCell)
{
//An object that uniquely identifies a row indicator cell
object o = hitInfo.RowHandle.ToString() + hitInfo.Column.FieldName;
if (hitInfo.Column.FieldName == "PHASEKIND")
{
string text = "1固定2待定3弹性4关键5跟随6行人7自行车8机动车";
info = new ToolTipControlInfo(o, text, "输入含义");
}
}
//Supply tooltip information if applicable, otherwise preserve default tooltip (if any)
if (info != null)
e.Info = info;
} 4，设置单元格的显示样式
实现gridview 的CustomColumnDisplayText事件
//修改显示样式
private void gridView1_CustomColumnDisplayText(object sender, DevExpress.XtraGrid.Views.Base.CustomColumnDisplayTextEventArgs e)
{
List<string> boolColns = new List<string> { "NO_DETCT_PHS_TOGETHER", "PED_VEH_TOGETHER", "UNDETERMINED_PHS_APPEAR", "ROAD_SECTION_PED"
, "INUSING"};
if (boolColns.Contains(e.Column.FieldName))
{
switch (e.Value.ToString().Trim())
{
case "1":
e.DisplayText = "是";
break;
case "0":
e.DisplayText = "否";
break;
default:
break;
}
}
}
