In my Form I have this code to open my report on a click of Button:

private void btnGroupOther_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e)

{

    LayoutControl lc = new LayoutControl();

    lc.Dock = DockStyle.Fill;

    DateEdit FirstDate = new DateEdit();

    DateEdit LastDate = new DateEdit();

    lc.AddItem(Resources.firstdate, FirstDate).TextVisible = true;

    lc.AddItem(Resources.seconddate, LastDate).TextVisible = true;

    lc.Height = 70;

    this.Controls.Add(lc);

    this.Dock = DockStyle.Top;

    if (DevExpress.XtraEditors.XtraDialog.Show(lc, " ", MessageBoxButtons.OKCancel) == DialogResult.OK)

    {

        RepProductionGroupOther report = new RepProductionGroupOther();

        report.DataSource = paint.RepProductionGroupOther(Convert.ToDateTime(FirstDate.EditValue).ToString("MM/dd/yyyy"),

            Convert.ToDateTime(LastDate.EditValue).ToString("MM/dd/yyyy"));



        report.ShowRibbonPreviewDialog();

    }

}

In my header report I have two xrLabel; the first one txtFirstDate and the second one txtLastDate. I want to show the value of FirstDate DateEdit control in txtFirstDate and the value of LastDate DateEdit control in txtLastDate.

How can I do that, the DataSource of the report is sql stored procedure.

It has two Parameters: @FirstDate and @LastDate.

Thanks in advance

I suggest you to go through XtraReport documentation:
Request and Pass Report Parameter Values

private void button1_Click(object sender, EventArgs e) {

    // Create a report instance. 

    XtraReport1 report = new XtraReport1();



    // Obtain a parameter and set its value. 

    report.Parameters["parameter1"].Value = 30;



    // Hide the Parameters' UI from end-users (if you did not hide it at design time). 

    report.Parameters["parameter1"].Visible = false;



    // Show the report's print preview depending on your target platform. 

    // ... 

}

Check the "Custom Parameter Editors" section in above documentation
Custom editor implementation for parameters varies depending on your application's platform:

• 
  

  Windows Forms

  
  
  

  In Windows Forms applications, you can provide custom parameter editors in the XtraReport.ParametersRequestBeforeShow event handler.

  
  
  

  For a code sample, see Provide Custom Editors for Report Parameters.
