You can restrict user to click on Refresh Button on Browser.

The think you need to do is you have to check the Post back of Page.

On Page Load,

If(Page.ISPostBack)
  {
   // Store Db data into Database.
  }

And After that Reset All the field.

I created a new class that my page inherits from that basically adds a session variable and a form field and then tracks the two to see if the user hit the F5 button. There is a article on it here in code project somewhere (I didn't create the original, but modified to fit my needs), I just can't seem to find the link.

You could also look at other solutions like.

Hi all,

Currently i am in login page(Suppose in window1 ) after validation i m opening new (Window 2)

<
ClientScript.RegisterStartupScript(Me.GetType(), "", String.Format("<script>window.open('UserSetting1.aspx','ReportWindow', 'width=400,height=200,status=no,toolbar=no,menubar=no,location=yes,scrollbars=yes,resizable=no');</script>"))
>

from window 2 user will select hospital name from usersetting1.aspx after this Window 2 will get close and it should go the window1 and instead of login.aspx url should be index.aspx ......

I am doing this using
<

Dim strScript As String
strScript = "<script language=javascript>" & vbCrLf & _
"window.opener.location.reload('index.aspx');window.close();" & _
vbCrLf & "</script>"
If Not ClientScript.IsClientScriptBlockRegistered("") Then
ClientScript.RegisterStartupScript([GetType], "", strScript)

>

This closing window2 and redirecting to the index.aspx in window1 but above code is working fine for Internet explorer but not workng for firefox Please Help to find the solution

Thanks ,

hey man sorry from i will keep this thing in mind but please help to find the solution this time......

Firefox is displaying this message.

To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.

Well, as I said, install firebug and debug JS. Firebug is an excellent tool and can tell you where exactly is the problem.

Can anyone tell me how to reflect changes immediately in GridView.

Thanks,
Nagendra.

u Call the bind method outside postback or after saving call the bind method

nagendrathecoder25-Aug-09 0:51

25-Aug-09 0:51

No, i have used inbuilt SqlDataSource with GridView but just for displaying data.

I am doing editing manually, which don't have any connection with SqlDataSource.

You need to re-bind the gridview after update. If you are binding the gridview on page_load, ensure you are doing IsPostBack check.

This is my code for GridView and DataSource

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False"
                                    DataKeyNames="LocationCode" DataSourceID="SqlDataSource1" OnSelectedIndexChanged="GridView1_SelectedIndexChanged">
                                    <Columns>
                                          <asp:CommandField ShowSelectButton="True" SelectText="Edit" />
                                          <asp:BoundField DataField="LocationCode" HeaderText="Location Code" ReadOnly="True"
                                                SortExpression="LocationCode" />
                                          <asp:BoundField DataField="LocationDesc" HeaderText="Desciption" SortExpression="LocationDesc" />
                                    </Columns>
                              </asp:GridView>
                              <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="Data Source=COMP2;Initial Catalog=Inventory;User ID=sa;Password=pes"
                                    ProviderName="System.Data.SqlClient" SelectCommand="SELECT [LocationCode], [LocationDesc] FROM [Location_Master] ORDER BY [LocationCode]">
                              </asp:SqlDataSource>

I am editing data in database manually by using SqlCommand class ExecuteScalar method like this.......

protected void btnSave_Click(object sender, EventArgs e)
      {
            //This method will update a record into Location_Master table
            try
            {
                  string connectionString = ConfigurationManager.AppSettings["ConnectionString"];
                  SqlConnection connection = new SqlConnection(connectionString);
                  connection.Open();

                  string save = "";


                        //String for updating a record into table
                        save = "update Location_Master set LocationDesc='" + txtBoxLocDesc.Text + "',CreatedBy='"+Session["userName"].ToString();
                        save = save + "',LastUpdateDate='" + System.DateTime.Now + "' where LocationCode='"+txtBoxLocCode.Text+"'";


                  SqlCommand saveCommand = new SqlCommand(save, connection);
                  int rowsAffected = saveCommand.ExecuteNonQuery(); //Store the no. of rows added or updated

                  connection.Close();


            }
            catch (System.Exception ex)
            {
                  lblMessage.Text = ex.Message;
                  lblMessage.Visible = true;
            }
      }

After clicking that Save button, database is updating, but changes are not reflecting to GridView, i have to execute my application again to see changes in GridView.

You have to use ExecuteScalar instead of ExecuteNonQuery.
int rowsAffected =(int) saveCommand.ExecuteScalar();

I don't think this will make much difference, we mostly use ExecuteNonQuery for updation purpose, i am getting my updations fine.
