by 鸟栖沙岩 keys 分享 1482213036220

一、GridControl的删除操作

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["Code"].ToString());
         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.CustomColumnDataEventArgse)
{
     GridView View = sender as GridView;
     if (e.RowHandle >= 0)
     {
         object needAlert =View.GetRowCellValue(e.RowHandle, View.Columns["needAlert"]);
         if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value)
         {
            decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["Value"]));
             objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]);
             objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]);
             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["MinValue"]));
                decimal gridColumn1 = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]));
                if (gridColumn2 > AverValue || AverValue > gridColumn1)
                {
                    if (!ht.ContainsKey("pic"))
                        ht.Add("pic", GetImage(1));
                    e.Value = ht["pic"];
                }
             }
         }
     }
}

/// <summary>
/// 由资源文件获取图片
/// </summary>
/// <param name="key"></param>
/// <returns></returns>
byte[] GetImage(int key)
{
     Image img =DevExpress.Utils.Controls.ImageHelper.CreateImageFromResources(string.Format("RiverSys.Resources.{0}.gif",key.ToString()), typeof(RiverInfos).Assembly);
     returnDevExpress.XtraEditors.Controls.ByteImageConverter.ToByteArray(img,ImageFormat.Gif);
}

/// <summary>
/// 动态根据条件设置行样式
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void 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["needAlert"]);
         if (needAlert != null &needAlert != DBNull.Value && needAlert.ToString().Trim() !="0" & View.GetRowCellValue(e.RowHandle,View.Columns["Value"]) != DBNull.Value)
         {
            decimal AverValue = Convert.ToDecimal(View.GetRowCellValue(e.RowHandle, View.Columns["Value"]));
             objectMinValue = View.GetRowCellValue(e.RowHandle,View.Columns["MinValue"]);
             objectMaxVlaue = View.GetRowCellValue(e.RowHandle,View.Columns["MaxValue"]);
             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]["Color"].ToString();
         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]["Color"] =Common.RGB_HEX(colorVal.ToArgb());
     }
}

四、关于 GridControl 验证示例

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]["Color"].ToString();
         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]["Color"] =Common.RGB_HEX(colorVal.ToArgb());
     }
}

四、关于 GridControl 验证示例

/**//// <summary>
/// 初始化GridView，绑定数据
/// </summary>

private void GridViewBindData(string parentId)
{
this.gridView1.Columns.Clear();
this.FDs= areaSetupActionHelper.getDsRegionByParentId(parentId);

    RepositoryItemTextEdit textEditReg_Id = newRepositoryItemTextEdit();

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

    this.gridView1.Columns["reg_id"].ColumnEdit =textEditReg_Id;

    TreeListNode node =this.treelArea.FocusedNode.ParentNode;

}
