WebUserControl를 Access하거나 값을 Send하기

WebUserControl를 Access하거나 값을 Send하기


인터페이스를 써야하고 뭐가 복잡할거 같았다.
그냥 master과 content로 구성된 페이지에서 content 페이지에 삽입된
webusercontrol로 구성된 textbox1에 값을 넣고 값이 있으면 엑세스 하려고 한다.

            TextBox txtBox = (TextBox)WebUserControl1.FindControl("TextBox1");
            txtBox.Text = "aaaatest";            //Usercontrol로 value send
            txt_BranchName.Text = txtBox.Text;   //Usercontrol의 value request

정말로 간단하다.

컨트롤 타입으로 변수만들고 Findcontrol하여 usercontrol에 ID textbox1찾아 지정해주면 된다

Build a Webusercontol and pass values.

.Add a new class "User" and add a property, Name.
This class can have any number of methods or properties which can be passed out from the usercontrol.

public class User
{
    private string _name;
    public string Name
    {
        get { return _name; }
        set { _name = value; }
    }
}

.From the File menu add New File and select Web User Control
.Add a Label, TextBox and Button Contol.
.Declare the delegate with 2 parameters, sender and the class "User"

// declare the delegate.
    public delegate void UserEventHandler(object sender, User CUser);
// daclare the event - event publisher.
    public event UserEventHandler GetUser;

.On Button Click event

  protected void Button1_Click(object sender, EventArgs e)
    {
        User _user = new User();
        _user.Name = TextBox1.Text;
        if (GetUser != null)
            GetUser(sender, _user);
    }

.Compile the Web user control.
.Create a aspx page and drag and drop the web user control from the solution explorer.

<uc1:WebUserControl ID="WebUserControl1" runat="server" />

. Add 2 two labels to the aspx page
.Update the first label from the label of the webusercontrol

// get the label value from the user control
  Label1.Text = ((Label)WebUserControl1.FindControl("Label1")).Text;

.Subscribe to the event of the web user control.

 // subscribe to the event - observer pattern
  WebUserControl1.GetUser += new UserEventHandler(WebUserControl1_GetUser);
void WebUserControl1_GetUser(object sender, User CUser)
    {
        Label2.Text = CUser.Name;
    }

asp.net 포럼에서 UserControl에 데이타바인드하는 관련 소스가 있어서 갈무리했다.

WebUserControl WebUserControl1 = (WebUserControl)FindControl("WebUserControl1");

TextBox TextBox1 = (TextBox)WebUserControl1.FindControl("TextBox1");

GridView GridView1 = (GridView)WebUserControl1.FindControl("GridView1");

TextBox1.Visible = false;

DataSet ds = Class1.Getdata();

GridView1.DataSource = ds;

GridView1.DataBind();
