Hi,
I have a flickering problem while loading crystal report with data from a datagridview. And when flickering the program freezes until loading is complete. How can i resolve this problem?? Thank you for any help.
Here is my code

C#

DataSet4 ds = new DataSet4();
DataTable t = ds.Tables.Add("stock");
t.Columns.Add("Item_Name", Type.GetType("System.String"));
t.Columns.Add("Store", Type.GetType("System.String"));
t.Columns.Add("Total_Stock", Type.GetType("System.String"));
t.Columns.Add("Product_Code", Type.GetType("System.String"));
t.Columns.Add("Which", Type.GetType("System.String"));

DataRow r;

string ItemName = string.Empty;
string sto = string.Empty;
string totostok = string.Empty;
string pcode = string.Empty;
string wich = string.Empty;

for (int i = 0; i < dataGridView1.RowCount; i++)
{
    pcode = dataGridView1.Rows[i].Cells[0].Value.ToString();
    ItemName = dataGridView1.Rows[i].Cells[1].Value.ToString();
    sto = dataGridView1.Rows[i].Cells[2].Value.ToString();
    totostok = dataGridView1.Rows[i].Cells[3].Value.ToString();
    wich = cmbFilter.Text;

    r = t.NewRow();
    r["Product_Code"] = pcode;
    r["Item_Name"] = ItemName;
    r["Store"] = sto;
    r["Total_Stock"] = totostok;
    r["Which"] = wich;
    t.Rows.Add(r);

    CrystalReport4 objRpt = new CrystalReport4();
    objRpt.SetDataSource(ds.Tables[1]);
    crystalReportViewer1.ReportSource = objRpt;
    crystalReportViewer1.Dock = DockStyle.Fill;
    crystalReportViewer1.Refresh();
    crystalReportViewer1.Show();
}

I suggest you add the following meta tags:

C#

<meta http-equiv="Page-Enter" content="blendTrans(Duration=0)">
<meta http-equiv="Page-Exit" content="blendTrans(Duration=0)">

Thank you for the response mailganesh2004, but my application is a windows(Desktop) application not a web app

Then why didnt you tag it!? Leaving people wondering if you are working on ASP.Net, WPF, WinForms...

override create-param property of form,

C#

/// <summary>
/// This method written for avoid flikering while loading timetable
/// </summary>
/// <value></value>
/// <returns></returns>
/// <remarks></remarks>
protected override CreateParams CreateParams {
    get {
        CreateParams cp = base.CreateParams;
        cp.ExStyle = cp.ExStyle | 0x2000000;
        return cp;
    }
}
//CreateParams

Happy Coding!
:)
