Very straightforward, very nice. Glad to see someone shows an up-to-date way to update both the parent and a child object.

Hi
Kindly can u make a video on how to render manually inputselect using rendertreebuilder ?

Sammy

Could you make a table for the objects in details

I have written code and it is rendering the inputselect but with no items in the list...

internal RenderFragment CreateCustomEditor(KeyValuePair<string, object> cEditor) => builder =>
{
if (cEditor.Value is ComboBoxEdit)
{
var c = cEditor.Value as ComboBoxEdit;

PropertyInfo prop =

builder.OpenComponent(0,

var value = prop.GetValue(mItem);

builder.AddAttribute(1, "Value", value);
builder.AddAttribute(2, "class", "form-control h-100 w-100");

builder.AddAttribute(4, "ValueChanged",

(this,
(this, __value => prop.SetValue(mItem, __value),

// Create an expression to set the ValueExpression-attribute.
var constant = System.Linq.Expressions.Expression.Constant(mItem, mItem.GetType());
var exp = System.Linq.Expressions.MemberExpression.Property(constant, c.FieldName);

var lamb =

builder.AddAttribute(5, "ValueExpression", lamb);

builder.OpenElement(6, "Option");
builder.AddAttribute(7, "Value", "Wild");
builder.AddContent(8, "Wild");
builder.CloseElement();

//builder.AddMarkupContent(6, "<option
//builder.AddMarkupContent(7, "<option

builder.CloseComponent();

@*<InputSelect Id="name" Class="form-control"
<option value="Wild">Wild</option>
<option
<option
</InputSelect>*@
}

};

It would be of great help if you can make a Udemy video on how to create an Invoicing application that manages Inventory, Customers Credit, Customer Payments Email, Invoice, Send SMS, for sure you will have many students in the future
