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：
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
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);
}
}
}
.csharpcode, .csharpcode pre
{
font-size: small;
color: black;
font-family: consolas, "Courier New", courier, monospace;
background-color: #ffffff;
/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }
.csharpcode .rem { color: #008000; }
.csharpcode .kwrd { color: #0000ff; }
.csharpcode .str { color: #006080; }
.csharpcode .op { color: #0000c0; }
.csharpcode .preproc { color: #cc6633; }
.csharpcode .asp { background-color: #ffff00; }
.csharpcode .html { color: #800000; }
.csharpcode .attr { color: #ff0000; }
.csharpcode .alt
{
background-color: #f4f4f4;
width: 100%;
margin: 0em;
}
.csharpcode .lnum { color: #606060; }
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);
}
