6/5/2023 0 Comments Winform treeview![]() ![]() Inside traditional Windows Forms data binding, Reflection is used to format and parse values between the two participants. Rather, there must be a TreeNode object for each item of the data source. We cannot bind the TreeView control itself to a data source. ■ Imperative data binding -> full control when creating TreeNode objects The binding details like DataSource and DataMember are known by the BindingSource object, whereas the bound control only refers to the BindingSource object. In order to simplify data binding, we can use a BindingSource. New Binding("Text", this.bindingSource2, "FullName")) The data source object is a DataSet, from where we bind the DataTable2 current row’s “FullName” property. ![]() The binding is added to the DataBindings collection of a control and refers to the control’s “Text” property. New Binding("Text", this.dataSet11, "DataTable2.FullName")) ![]() Looking for a solution without these restrictions, I have come to the conclusion that a component is needed that mediates between the TreeView control and the data source similar to a Binding object. I’ve been looking for solutions and found one or the other, however, they used a subclass of the TreeView control or subclasses of TreeNode controls or even both. Unfortunately, the Windows Forms TreeView Control provides neither the DataSource and DataMember nor the BindingSource properties as we know it from the DataGridView and other controls. In my case, I have to implement data binding on a TreeView control for an existing Windows Forms Application. Sometimes, one is pushed back into the era of Windows Forms. ![]()
