kljde的专栏

想要的功能是菜单栏能隐藏，能展示。类似vs上属性栏，工具箱。 错误方法：之前在网上看的需要下载dockpanel.dll。。。。。。自己也手动写过一个dockpanel控件（designer中写的）。。。。。。 正确方法：第一步：添加一个dockmanager，点击dockmanager上的三角,再点击（Add Panel At Left 默认在左边）第二步：再往d

private void simpleButton1_Click(object sender, EventArgs e)        {            int int_monthes = Convert.ToInt32(txtYF.Text);            string str_Year = dtebegin.Text.Substring(0, 4);     

可以用Control.MousePosition获得当前鼠标的坐标，使用PointToClient计算鼠标相对于某个控件的坐标，如下Point screenPoint = Control.MousePosition;//鼠标相对于屏幕左上角的坐标Point formPoint = this.PointToClient(Control.MousePosition);//鼠标相对于窗体

public void Button5_Click(object sender, EventArgs e)        {            SaveFileDialog fbd = new SaveFileDialog();            fbd.Title = "选择路径";//窗体标题            fbd.Filter = "Excel文件(.xls)

具体从哪里参考的已经忘了。           private void gvStaff_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)        {            if (e.Info.IsRowIndicator

private void treeFileWageColumn_BeforeCheckNode(object sender, DevExpress.XtraTreeList.CheckNodeEventArgs e)        {            if (!e.Node.Checked)            {                this.GV.Column

using Excel = Microsoft.Office.Interop.Excel;using System.Runtime.InteropServices;using System.Threading;using System.Data.OracleClient;添加以上引用        public void Button1_Click(object sender,

bool IsFloat(string str)        {            try            {                float.Parse(str);//int.Parse(str);//double.Parse(str);                return true;            }            ca

具体忘了从哪里参考来的。 private void treeDep_CustomDrawNodeIndicator(object sender, DevExpress.XtraTreeList.CustomDrawNodeIndicatorEventArgs e)        {            TreeList tr = sender as DevExpress.XtraTr

//鼠标右键  private void bgvXjgl_MouseDown(object sender, MouseEventArgs e)        {            GridHitInfo HIGL = bgvXjgl.CalcHitInfo(e.X,e.Y);            if (e.Button== System.Windows.Forms.Mous

我发现网上对于VgridControl的资料特别少。。。最近一直在自学这个控件。希望能多多与大家交流             for (int i = 0; i             {                VGridControl.SetCellValue(VGridControl.Rows[i], 0, null);            }
