【原创】DevExpress控件GridControl中的布局详解

在进行DevExpress控件GridControl的使用时,因控件的灵活性,所以用户会经常进行拖动控件的列,以达到自己满意的样式,

但下次再打开时系统就会重新还原到原有的布局风格,为了能够保持用户之前设置的风格,下次再打开时依然保持原有的风格。

在gridView中有两个方法:SaveLayoutToXml(保存布局),RestoreLayoutFromXml(恢复布局)

 以下是具体的代码:

private string systempath = "C:\\Program Files\\";
/// <summary>
/// 保存风格
/// </summary>
/// <param name="moduleid"></param>
/// <param name="saveType"></param>
private void SaveLayout(string moduleid, string saveType)
{
string path = systempath + "窗体风格\\" + moduleid+"\\";
string file = saveType + "view.xml";
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
m_gridView.SaveLayoutToXml(path
+file);
}
/// <summary>
/// 加载风格
/// </summary>
/// <param name="moduleid"></param>
/// <param name="saveType"></param>
private void LoadLayout(string moduleid, string saveType)
{
string path = systempath + "窗体风格\\" + moduleid + "\\";
string file = saveType + "view.xml";
if (!Directory.Exists(path))
{
Directory.CreateDirectory(path);
}
if (!File.Exists(path + file))
return;
m_gridView.RestoreLayoutFromXml(path
+ file);
}
/// <summary>
/// 布局变化时产生事件
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void m_gridView_Layout(object sender, EventArgs e)
{
SaveLayout(m_controlManager.Owner.ModuleId,
"Master");
}

/// <summary>
/// gridcontrol load Event
/// </summary>
/// <param name="sender">The source of the event.</param>
/// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param>
private void m_gridControl_Load(object sender, EventArgs e)
{
SaveLayout(m_controlManager.Owner.ModuleId,
"Default");

LoadLayout(m_controlManager.Owner.ModuleId,
"Master");
}
