    Hi @hidaextnet,

    So, are the controls that you mean - LoanDate, EmpName2, etc.?

    What are those controls? Is it Ext.NET controls? I cannot see them in the code snippet.

    Did you check (debug) these code lines are actually executed?
    LoanDate.Text = dtrt.Rows[0]["LOAN_DATE"].ToString();
    EmpName2.Text = dtrt.Rows[0]["EMPLOYEE_NAME"].ToString();
    etc.

    By the way, you don't need a [DirectMethod] attribute for a DirectEvent handler.

    These are asp controls

    Did you check (debug) these code lines are actually executed?
    LoanDate.Text = dtrt.Rows[0]["LOAN_DATE"].ToString();
    EmpName2.Text = dtrt.Rows[0]["EMPLOYEE_NAME"].ToString();
    etc.

    I've checked , these lines are executing.

    To get an ASP.NET control updated during a DirectEvent/DirectMethod you have to call its Update method.
    LoanDate.Text = dtrt.Rows[0]["LOAN_DATE"].ToString();
LoanDate.Update();
