How to use Delete fuction from business logic layer

Question

Currently I'm working on a Windows Project. I have a data access layer and business logic layer. I made a function of Delete in it. But I don't know how to use it on form. I give an example to understand you. My Insert Coding on form is following- MasterClothDesign obj = new MasterClothDesign(); // MasterClothDesign is the class of Business Logic Layer obj.Cloth_Design_Name = txtDesignName.Text; obj.Save(); In Business Logic Layer I made the following function of delete. public void DeleteBy(IDbTransaction txn) { new MasterClothDesignData(txn).MasterClothDesignData_DeleteByClothDesignId(Cloth_Design_Id); } Delete Coding on form is following private void btnDelete_Click(object sender EventArgs e) { MasterClothDesign obj = new MasterClothDesign(); obj.Cloth_Design_Id = Convert.ToInt32(lblDesignId.Text); obj.DeleteBy(); } It gives the error on DeleteBy. So how this function should be write on form? Thanks in advance.

Use an entity to assign variable in your Main form. Then in business logic layer retrieve the variable value from entity and use it to perform action if u see the following example u will get an idea public class enty { public enty() { } string name; public string Name { get { return name; } set { name = value; } } } public class businesslogic : enty { public businesslogic() { } public bool isnameset() { if(! string.IsNullOrWhiteSpace(Name)) return true; else return false; } } public partial class Form1 : Form { public Form1() { InitializeComponent(); } businesslogic ac = new businesslogic(); private void button1_Click(object sender EventArgs e) { ac.Name = sady; bool flg = ac.isnameset(); if (flg) MessageBox.Show(Test); } }
