在项目开发中,并不是每个RepositoryItem都可以编辑,往往是有条件性的,需要譬如当A列等于“AA”的时候,B列才可编辑,实现起来在ShowingEditor事件中最为方便,并且加入toolTip提示显得人性化。
代码如下:
private void gvLampConfig_ShowingEditor(object sender, System.ComponentModel.CancelEventArgs e) { GridView _view = sender as GridView; if (_view.FocusedColumn.Name == "colSavePowerGp1")//当列等于colSavePowerGp1 { string _type = _view.GetRowCellDisplayText(gvLampConfig.FocusedRowHandle, "OptStatusText_gp1"); if (!_type.Equals("节能"))//当列OptStatusText_gp1的列值不等于OptStatusText_gp1 { e.Cancel = true; ShowToolTip(toolTipController, "提示", "当是【调光状态】是节能模式情况,可以设置该值!"); } } } public static void ShowToolTip(ToolTipController toolTip, string title, string content) { Point _mousePoint = Control.MousePosition; toolTip.ShowHint(content, title, _mousePoint); }
代码效果:
为了调高代码复用性,方便后续使用,可以这样子封装一下:
/// <summary> /// 设置RepositoryItem是否可编辑 /// 说明: /// 在ShowingEditor事件中使用 /// </summary> /// <param name="view">GridView</param> /// <param name="focusedColumnName">需要设置的列名称</param> /// <param name="conditonHanlder">判断委托</param> /// <param name="toolTip">ToolTipController</param> /// <param name="title">当条件委托成立的时候提示标题</param> /// <param name="content">当条件委托成立的时候提示内容</param> /// <param name="e">CancelEventArgs</param> private void CustomShowingEditorWithToolTip(GridView view, string focusedColumnName, Func<object, bool> conditonHanlder, ToolTipController toolTip, string title, string content, CancelEventArgs e) { if (view.FocusedColumn.Name.Equals(focusedColumnName)) { if (conditonHanlder(view.GetFocusedRow())) { e.Cancel = true; Point _mousePoint = Control.MousePosition; toolTip.ShowHint(content, title, _mousePoint); } } }
代码使用:
private void gvLampConfig_ShowingEditor(object sender, System.ComponentModel.CancelEventArgs e) { GridView _view = sender as GridView; CustomShowingEditorWithToolTip(_view, "colSavePowerGp1", arg => ((LampSelfRunCfgParamter)arg).OptStatusText_gp1 != "节能", toolTipController, "提示", "当是【调光状态】是节能模式情况,可以设置该值!", e); }
希望有所帮助!
