c#,DEV控件使用

使用下面的示例代码，以获得当前编辑的值。

string editingValue;

if(gridControl1.KeyboardFocusView.IsEditing)

editingValue = gridControl1.KeyboardFocusView.EditingValue.ToString();

///

/// 由资源文件获取图片 ///

/// byte[] GetImage(int key) {

Image img = DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format(\sources.{0}.gif\ return DevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img, ImageFormat.Gif); }

private void rILinkEditInfoDel_Click(object sender, EventArgs e)

{

if (XtraMessageBox.Show(\请确定是否删除当前记录？\\警告\MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes) {

DataRow row = gvInfos.GetDataRow(gvInfos.FocusedRowHandle); delByCode(row[\ XtraMessageBox.Show(\操作成功！\ }

}二、绑定非数据表中列

Hashtable ht = new Hashtable();

private

void

gridView6_CustomUnboundColumnData(object

sender,

DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e) {

GridView View = sender as GridView; if (e.RowHandle >= 0) {

object

needAlert

=

View.GetRowCellValue(e.RowHandle,

View.Columns[\

if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != \alue(e.RowHandle, View.Columns[\alue\alue) {

decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns[\alue\ object MinValue View.Columns[\alue\ object MaxVlaue View.Columns[\alue\

if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != \& MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != \ {

decimal

gridColumn2

= =

Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns[\alue\ decimal gridColumn1 Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns[\alue\ if (gridColumn2 > AverValue || AverValue > gridColumn1) {

if (!ht.ContainsKey(\ ht.Add(\ e.Value = ht[\ } } }

} }

///

/// 由资源文件获取图片 ///

/// byte[] GetImage(int key) {

Image

img

=

= =

View.GetRowCellValue(e.RowHandle, View.GetRowCellValue(e.RowHandle,

DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format(\sources.{0}.gif\ return

ImageFormat.Gif); }

///

/// 动态根据条件设置行样式 ///

///

DevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img,

gridView6_RowStyle(object sender,

DevExpress.XtraGrid.Views.Grid.RowStyleEventArgs e) {

GridView View = sender as GridView; if (e.RowHandle >= 0) {

object

needAlert

=

View.GetRowCellValue(e.RowHandle,

View.Columns[\

if (needAlert != null & needAlert != DBNull.Value && needAlert.ToString().Trim() != \alue(e.RowHandle, View.Columns[\alue\alue) {

decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns[\alue\

object MinValue View.Columns[\alue\

object MaxVlaue View.Columns[\alue\

= =

View.GetRowCellValue(e.RowHandle, View.GetRowCellValue(e.RowHandle,

if (MinValue != DBNull.Value & MinValue != null & MaxVlaue.ToString() != \& MaxVlaue != DBNull.Value && MaxVlaue != null & MaxVlaue.ToString() != \ {

decimal gridColumn2 = Convert.ToDecimal(MinValue); decimal gridColumn1 = Convert.ToDecimal(MaxVlaue); if (gridColumn2 > AverValue || AverValue > gridColumn1) {

e.Appearance.ForeColor = Color.Red;

e.Appearance.BackColor = Color.LightGray; } }

} }

}三、GridControl 中颜色选择控件

private

void

gvMapColor_CustomUnboundColumnData(object

sender,

DevExpress.XtraGrid.Views.Base.CustomColumnDataEventArgs e) {

GridView view = sender as GridView;

DataView dv = view.DataSource as DataView; if (e.IsGetData)

{

string strVal = dv[e.ListSourceRowIndex][\ if (strVal != \ {

//e.Value = DevExpress.Utils.StyleLayout.ColorFromString(strVal); e.Value = Common.HexToColor(strVal); }

}

else {

//Color colorVal DevExpress.Utils.StyleLayout.ColorFromString(e.Value.ToString()); Color colorVal = (Color)e.Value;

dv[e.ListSourceRowIndex][\al.ToArgb()); }

}四、关于 GridControl 验证示例

/**////

/// 初始化GridView，绑定数据 ///

///

this.gridView1.Columns.Clear();

this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId); this.gridCArea.DataSource =this.FDs.Tables[0].DefaultView;

this.gridView1.Columns[\

this.gridView1.Columns[\

this.gridView1.Columns[\区划编号\ this.gridView1.Columns[\区划名称\ this.gridView1.Columns[\父区划编号\ this.gridView1.Columns[\区划描述\ this.gridView1.Columns[\ this.gridView1.Columns[\

RepositoryItemTextEdit textEditReg_Id = new RepositoryItemTextEdit(); textEditReg_Id.Mask.EditMask =parentId+\

textEditReg_Id.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.Regular;

this.gridView1.Columns[\

this.gridView1.Columns[\

TreeListNode node = this.treelArea.FocusedNode.ParentNode; string fid = node==null?\alue(\ DataSet ds = areaSetupActionHelper.getDsRegionByParentId(fid);

RepositoryItemLookUpEdit lookUEParent_Id = new RepositoryItemLookUpEdit(); lookUEParent_Id.Columns.Add(new LookUpColumnInfo(\区划编号\ lookUEParent_Id.Columns.Add(new LookUpColumnInfo(\区划名称\

=

lookUEParent_Id.DataSource = ds.Tables[0].DefaultView;

lookUEParent_Id.ValueMember = \ lookUEParent_Id.DisplayMember = \

this.gridView1.Columns[\}

/**////

/// gridView单元格验证的相关处理程序 ///

///

private void gridView1_ValidatingEditor(object DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e) { if (e.Valid == false&this.gridView1.FocusedColumn.FieldName == \

{

e.ErrorText = \区划编号不合法！\\n应为父区划编号加2～3位数据组成！\ }

if (this.gridView1.FocusedColumn.FieldName == \ {

Regex reg=new Regex(@\ Match m=reg.Match(e.Value.ToString().Trim()); if (m.Length != e.Value.ToString().Trim().Length) { e.Valid = false;

e.ErrorText = \区划名称应为汉字\\n长度为1至20\ } }

}

private void gridView1_InvalidValueException(object sender, InvalidValueExceptionEventArgs e) {

if (MyDialog.Alert(\ 您所填写的内容不符合规则\\n 要放弃您刚才对此项所做的更改吗？\\您所编辑的内容不符合规则\MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.Yes)

{

e.ExceptionMode = ExceptionMode.Ignore; } }

/**////

/// gridView行验证的相关处理程序

///

private void gridView1_ValidateRow(object DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e)
