C# Winform Click Event for Programmically created user contr

I have created a user control which contains profile pix, Name, employee No, Branch (similar to contact card). On a form i have placed a flowlayoutview and wanted to display the user control for every row on the table name users.

private void Users_Load(object sender, EventArgs e)
{
load_grid();
Load_UserList();
}
void Load_UserList()
{
string conn = @"Data Source=(LocalDB)\MSSQLLocalDB;Initial Catalog=ifz001;";
SqlConnection Connect = new SqlConnection(conn);
Connect.Open();
try
{
var cmdQuery = "SELECT * FROM Users";
var cmdCount = "SELECT COUNT (*) FROM Users";
SqlCommand cmdQ = new SqlCommand(cmdQuery, Connect);
SqlCommand cmdC = new SqlCommand(cmdCount, Connect);
int count = (int)cmdC.ExecuteScalar();
var ad = new SqlDataAdapter(cmdQuery, Connect);
DataSet ds = new DataSet();
DataTable dt = new DataTable();
ad.Fill(dt);
for (int i = 0; i < dt.Rows.Count ; i++)
{
UserLst1 uList = new UserLst1();
uList.Name = "userlst11" + i;
uList.FullName.Text = dt.Rows[i]["fname"].ToString();
uList.Emp_Id.Text = dt.Rows[i]["emp_no"].ToString();
uList.Department.Text = dt.Rows[i]["dept"].ToString();
uList.Branch.Text = dt.Rows[i]["brn"].ToString();
uList.ProfilePix.Image = Image.FromFile(dt.Rows[i]["img_path"].ToString());
flowLayoutPanel1.Controls.Add(uList);
}
Connect.Close();
}
catch(Exception u)
{
MessageBox.Show(u.Message);
}
}

I didn't drag and drop the user control in the flowlayoutview instead used the above code to display them in the flowlayoutview. (UserLst1 uList = new UserLst1(); uList.Name = "userlst11" + i;)

And it works, displays all the users details in the user control for each row.

Now the problem is; i need to create a click event on the user control so that the related user control id is populated to textBox1.

The User Control --> uList.Name = "userlst11" + i;

count is row number in table users

How do i create Click Event for each User Control (ulist.Name) .

the issue I face is, the user control name on increment which is uList.Name = "userlst11" + i;. where do I place the click event. I want click event for user control (ulist).

Hi, Please add a button control in your user control as you done for remaining label controls. and in your for loop, assign a click handler with your custom method which accepts object and arguments as shown below. Now when you click on any button in the control this custom method will be called by sending respective user control object.
Now, you can get Name of the clicked user control as follows.
private void button1_Click(object sender, EventArgs e)
       {
           if(sender is UserLst1)
           {
               var mycontrol = (UserLst1)sender;

               int controlcount = int.Parse(mycontrol.Name.Replace("userlst11", ""));
           }
       }
