Ext.NET components using aspx.cs(code behind script)

Time:01-27

My apologies for breaking the rules of asking questions. I am a learner and battling to find the right source/link to learn more about creating model, store and grid using the cs/code behind the script.

I managed to create the buttons below, I now want to do the same for the store, model and grid.

//aspx.cs file
  protected void Page_Load(object sender, EventArgs e)
        {
            //creating button
            Ext.Net.Button loadButton = new Ext.Net.Button();
            loadButton.ID = "LoadPageContent";
            loadButton.Text = "Load Page Content";
            loadButton.Click  = loadPageContentButton_click;
            loadButton.AutoPostBack = true; //remove because it forces the entire page to reload.

            this.MyViewPort.Items.Insert(0, loadButton); //adding the button to the static viewport

        }

I have no idea how to achieve this. I tried searching. All the solutions I see on the web are using either javascript or static elements. Below is the model, store and grid that I want to create using the cs file (Ext.NET). May anyone please help me with the link where I can learn more about this because there is more that I still need to learn? I checked this link and it is not helping me this and this one too,

Ext.define('EmployeeListModel', {
                extend: 'Ext.data.Model',
                fields: [

            });

                                    break; //no need to continue looping
                                }
                            }

                            if (madeChanges) {
                                UpdateEmployee(element["newValues"], element); //the second parametor will help us set the database generated data(emp code, login, registration date)
                            }

CodePudding user response:

In case anyone is stuck on creating the model, store and the grid on on Ext.NET, I will post this solution. But I still need the link to where I can learn about Ext.NET. I got what I have with the help of intelligence.  First you need a model. Remember that on ExtJS, when defining the your new model, you extend extend: 'Ext.data.Model', here on Ext.NET, a model is just a class. Your class has to inherit (extend) the model class. Below is my model. please do not mind my EmployeeOML empOML = new EmployeeOML(); it is just a class from another model. This class has all the fields from the database. enter code here will return a string column/field/property/variable name.

     

public class EmployeeModel:Model
    {
        EmployeeOML empOML = new EmployeeOML();
        public EmployeeModel()
        {
            this.Fields.Add(new ModelField(nameof(empOML.Id), ModelFieldType.Int));
            this.Fields.Add(new ModelField(nameof(empOML.Name), ModelFieldType.String));
            this.Fields.Add(new ModelField(nameof(empOML.Surname), ModelFieldType.String));
            this.Fields.Add(new ModelField(nameof(empOML.DateOfBirth), ModelFieldType.String));
            this.Fields.Add(new ModelField(nameof(empOML.Username), ModelFieldType.String));
            this.Fields.Add(new ModelField(nameof(empOML.Password), ModelFieldType.String));
            this.Fields.Add(new ModelField(nameof(empOML.LoginAttempts), ModelFieldType.Int));
            this.Fields.Add(new ModelField(nameof(empOML.RegisterDate), ModelFieldType.String));         }
    }

creating a store is just straight to the point. For the data source, I am getting the list from the database with all the fields we have on the above model

protected Store CreateStore()
{
Store myStore= new Store();
myStore.ID = "myStoreId";
myStore.Model.Add(new EmployeeModel()); 
myStore.DataSource = empSL.GetAllEmployee(); 
return myStore;
}

Finally, I created the grid panel below.

  

protected GridPanel CreateGridPanel(Store myStore)
        {
            GridPanel myPanel = new GridPanel();
            myPanel.ID = "employeeListPanel";
            myPanel.Store.Add(myStore);
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Employee Code", DataIndex = nameof(empOML.Id) });
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Full Name", DataIndex = nameof(empOML.Name) });
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Surname", DataIndex = nameof(empOML.Surname) });
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Birth Date", DataIndex = nameof(empOML.DateOfBirth) });
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Username", DataIndex = nameof(empOML.Username) });
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Password", DataIndex = nameof(empOML.Password) });
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Loggin attempts", DataIndex = nameof(empOML.LoginAttempts) });
            myPanel.ColumnModel.Columns.Add(new Column { Text = "Date Registed", DataIndex = nameof(empOML.RegisterDate) });
            return myPanel;
        }

The bonus code below is responsible for implementing these function calls. using functions is a choice.

var myStore = CreateStore();
var mgridPanel = CreateGridPanel(myStore);
int lastIndex = MyViewPort.Items.Count;
this.MyViewPort.Items.Insert(lastIndex, mgridPanel);

If any one has a link where I can read about using Ext.NET on the code behind, please kindly assist. I do not what to use static elements and also do not what to use ExtJS.
