如何在后面的代码中为具有子树和没有子树的asp树视图的节点设置单独的样式 [英] How to set separate style for a node that has child and no child of asp tree view in code behind

问题描述

我有动态绑定树视图中的品牌，类别和子类别的方案.我对RootNode-品牌，ParentNode-类别和ChildNode- SubCategory有不同的样式.不应单击父节点"和根节点"，只能单击子节点.所有这些都可以正常工作，但是我也有一个场景，一个类别可能没有子类别，但是它应该具有父节点样式，也可以单击它.我无法执行此操作.

Hi,

I have scenario which binds the Brand, category and sub categories in a treeview dynamically. I have separate styles for RootNode - Brand, ParentNode - Category and ChildNode- SubCategory. Parent Node and Root node should not be clicked only child nodes can be clicked. All this works fine but I have also a scenario that a Category may not have sub category but it should have parent node style and it can be clicked also. I am not able to do this.

Ex: Brand1
       Category1
           subCategory1.1
           subCategory1.2
       Category2
           subCategory2.1
           subCategory2.2
       Category3
       Category4
       Category5

在上面的示例中，Brand1，Category1和Category2应该不可单击，而只能单击子类别，也可以单击不包含任何子类别的Category. Brand1-应该有一种样式，所有主要类别应该有一种样式，所有子类别都应该有一种样式.

In the above example Brand1,Category1 and Category2 should not be clickable whereas only subcategories can be clicked and Category that does not have any subcategory can also be clicked. Brand1 - should have one style and all the main categories should have one style and all the sub categories should have one style.

Hi,
I have solved it by myself. I have created the treeview controls at runtime and that solved my problem.
