一直不太喜欢写一些东西，最近感觉记性大不如从前，还是把一些摸索的东西记录下来，方便以后使用。
DevExpress的报表设计器中原有的工具箱是支持删除，新增工具，但是工具箱却操作不方便，或者说在特定环境下，自己想要更改整个工具箱的布局，样式，以及操作方式的时候可以用以下方法实现：
1.拖拽一个ToolBoxControl
2.定义几个全局变量（多个事件中会用到）
private System.Drawing.Design.ToolboxItem itemToolLink = null;
private XRToolboxService xRToolboxService = null;
private Dictionary<DevExpress.XtraToolbox.ToolboxItem, System.Drawing.Design.ToolboxItem> toolboxItemsLink = new Dictionary<DevExpress.XtraToolbox.ToolboxItem, System.Drawing.Design.ToolboxItem>();
3.实现ToolBoxControl的MouseDown和MouseMove事件
private void toolboxControlReport_MouseDown(object sender, MouseEventArgs e)
{
DevExpress.XtraToolbox.ToolboxHitInfo hitInfo = toolboxControlReport.CalcHitInfo(e.Location);
if (hitInfo == null || !hitInfo.IsInItem || !toolboxItemsLink.TryGetValue(hitInfo.ItemInfo.Item, out itemToolLink))
{
itemToolLink = null;
}
}
private void toolboxControlReport_MouseMove(object sender, MouseEventArgs e)
{
if (itemToolLink != null)
{
toolboxControlReport.DoDragDrop(new DataObject(itemToolLink), DragDropEffects.Copy);
xRToolboxService.SetSelectedToolboxItem(itemToolLink);
xRToolboxService.SelectedToolboxItemUsed();
itemToolLink = null;
}
}
4.加载完成报表之后可执行如下代码
xRToolboxService = (XRToolboxService)reportDesigner1.ActiveDesignPanel.GetService(typeof(System.Drawing.Design.IToolboxService));
foreach (string text in xRToolboxService.CategoryNames)
{
DevExpress.XtraToolbox.ToolboxGroup group = new DevExpress.XtraToolbox.ToolboxGroup(text);
IDesignerHost designerHost = (IDesignerHost)reportDesigner1.ActiveDesignPanel.GetService(typeof(IDesignerHost));
System.Drawing.Design.ToolboxItem[][] array = XRToolboxService.GroupItemsBySubCategory(xRToolboxService.GetToolboxItems(text), designerHost);
System.Drawing.Design.ToolboxItem[][] array2 = array;
for (int i = 0; i < array2.Length; i++)
{
System.Drawing.Design.ToolboxItem[] array3 = array2[i];
for (int j = 0; j < array3.Length; j++)
{
DevExpress.XtraToolbox.ToolboxItem itemTool = new DevExpress.XtraToolbox.ToolboxItem();
itemTool.Name = itemTool.Caption = ((array3[j] is LocalizableToolboxItem) ? ((LocalizableToolboxItem)array3[j]).DisplayName : array3[j].DisplayName);
itemTool.Image = array3[j].Bitmap;
toolboxItemsLink.Add(itemTool, array3[j]);
group.Items.Add(itemTool);
}
}
toolboxControlReport.Groups.Add(group);
}
if (toolboxControlReport.Groups.Count != 0)
{
toolboxControlReport.SelectedGroupIndex = 0;
}
5.此时工具已经被正常加载到工具箱中，可实现手动拖拽等功能
