Question

我有3个按钮的带状表格.. 我想将标签式子窗体更改为Vertical，Horizontal或Cascade ... 有没有怎么做？

如果使用带有属性的frmmain

=的IsMdiContainer真

private void btn1_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
     form1 frm1 = new form1();
     frm1.MdiParent=this;
     frm1.Show();
}

private void btnVertical_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
     LayoutMdi(MdiLayout.TileVertical);
}

private void btnHorizontal_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
     LayoutMdi(MdiLayout.TileHorizontal);
}

private void btnCascade_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
     LayoutMdi(MdiLayout.Cascade);
}

问题是，当我按btnVertical更改布局时如何更改布局

Answer 1

要使LayoutMdi方法有效，只需从表单中删除XtraTabbedMdiManager或使XtraTabbedMdiManager.MdiParent属性无效，因为MdiLayout模式不适用于XtraTabbedMdiManager的标签：

void btnVertical_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)
{
     xtraTabbedMdiManager1.MdiParent = null; // turn off tabs
     LayoutMdi(MdiLayout.TileVertical);
}

作为替代解决方案，您可以使用DocumentManager尝试Native MDI View组件。

XtraTabbedMdiManager布局（平铺垂直，平铺水平。平铺级联）
