Example

The following codes is recommended to be placed inside PrepareDataBinding event if Runtime Data Binding method is utilized, but if DesignTime Data Binding method is utilized, then it's safe to place above codes inside InitializeLayout or PrepareDataBinding event since the columns collection have been determined earlier using DesignTime Data Binding.

C#	Copy Code
WebGrid1.RootTable.SelfReferencingSettings.Enabled = true; WebGrid1.RootTable.SelfReferencingSettings.ParentDataMember = "EmployeeID"; WebGrid1.RootTable.SelfReferencingSettings.ChildDataMember = "ReportsTo"; WebGrid1.RootTable.SelfReferencingSettings.ExpandColumnMember = "FirstName"; WebGrid1.RootTable.SelfReferencingSettings.ParentRootMode = ISNet.WebUI.WebGrid.ParentRootMode.UseParentRootValue; // A DropDownList is configured with a collection of the possible values of ParentRootValue WebGrid1.RootTable.SelfReferencingSettings.ParentRootValue = Int32.Parse(DropDownList1SelectedItem.Value);

Copy Code

WebGrid1.RootTable.SelfReferencingSettings.Enabled = true;
WebGrid1.RootTable.SelfReferencingSettings.ParentDataMember = "EmployeeID";
WebGrid1.RootTable.SelfReferencingSettings.ChildDataMember = "ReportsTo";
WebGrid1.RootTable.SelfReferencingSettings.ExpandColumnMember = "FirstName";
WebGrid1.RootTable.SelfReferencingSettings.ParentRootMode = ISNet.WebUI.WebGrid.ParentRootMode.UseParentRootValue;
// A DropDownList is configured with a collection of the possible values of ParentRootValue
WebGrid1.RootTable.SelfReferencingSettings.ParentRootValue = Int32.Parse(DropDownList1SelectedItem.Value);

Remarks

WebGrid.NET with Self Reference has a setting called ParentRootMode, which is a property where the root of the self referencing table point to. There are three options of ParentRootMode to determine where the self referencing table point to: UseParetRootValue, NullValue, SelfReferencingNode.

UseParentRootValue : UseParentrootValue is a property to show self reference table based on the parent value.
NullValue : NullValue is a property to show self reference table based on null value.
SelfReferencingNode : SelfReferencingNode is a property to show the self reference table based on only the parentnode which has reference.

In order to use ParentRootMode based on the UseParentRootValue, we need to define some major SelfReference settings. Please check sample code above.
