This article mainly introduces how to achieve TreeList recursive binding data in the Devexpress control, which has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

The TreeList control in Devexpress can achieve functions similar to TreeView.

TreeList recursively binds data in DataTable

Two watches. The first table is the parent node type, and the second table is the child node under each type.

Public void Bind () {this.TreeList.Clear (); DataTable dt= "query collections from the database"; if (dt.Rows.Count > 0) {TreeListNode node=treelist1.AppendNode ("id", NULL); node.SetValue= (0, "Name"); for (int itransitiondt.Rows.Countpolitics +) {TreeListNode nodeTemp=treelist1.AppendNode (dt.Rows [I] ["ID"], node); nodeTemp.SetValue (TreeListClomus1,dt.Rows [I] ["Name"]); nodeTemp.Tag=dt.Rows [I] GetChildNode (TreeListNode node, dt.Rows [I] ["ID"]);} public void GetChildNode (TreeListNode node, string parent) {DataTable dt= "query where id= from the database" + parent; if (dt.Rows.Count >) {for (int iDeposit I)
