I have a page with a gridview on it. The gridview can not be seen when the page is opened. There is a dropdownlist and a button on the page. The user is supposed to make a selection in the dropdown and then click the button (labeled "Go") and then the gridview appears. The problem is that the gridview appears in response to the dropdown selection, before the go button is clicked. I'm sure this is easy but how can I stop the gridview from appearing in response to a dropdown selection? The dropdown is called ddlfilter. This is the code I am using:
Part 1 (continued in next post):
Code:
<%@ Page Language="VB" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"[URL]>
<script runat="server">
Private Function GetColumnIndexByName(row As GridViewRow, SearchColumnName As String) As Integer
Dim columnIndex As Integer = 0
For Each cell As DataControlFieldCell In row.Cells
If TypeOf cell.ContainingField Is BoundField Then
If DirectCast(cell.ContainingField, BoundField).DataField.Equals(SearchColumnName) Then
Exit For
End If
End If
columnIndex += 1
Next
Return columnIndex
End Function
Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As GridViewRowEventArgs)
If Page.IsPostBack() Then
If ddlFilter.SelectedItem.Text.ToString() <> "- ALL -" Then
If e.Row.RowType = DataControlRowType.DataRow Then
e.Row.Cells(GetColumnIndexByName(e.Row, ddlFilter.SelectedItem.Text.ToString())).CssClass = "viscol"
End If............

I have a gridview control sitting in a jQuery Accordian. The data in the grid diplays fine, however in IE 6 the page numbers do not display when the pane of the accordian is first opened. If you open another pane and then re-open the pane containing the grid view the number appear. There is also no issue with IE7 or later or FF.

I following this article for sending SMS it is a winform application.. I have referenced all the Dll's to my asp.net application. I use an aspx page to detect a mobile device connected to a PC..... But it alwys shows COM 'n' Port could not be opened.
using SMS; using GsmComm.GsmCommunication; using GsmComm.PduConverter; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { GsmCommMain comm = new GsmCommMain(6, 9600, 300); comm.Open(); if (!comm.IsConnected()) { Response.Write("No Phone Connected"); } else { SmsSubmitPdu pdu = new SmsSubmitPdu("test", "+919999999999", ""); CommSetting.comm.SendMessage(pdu); } } }
EDIT:
I use the web development server that ships with Visual Studio... If go to Control Panel -> Phones & Modems -> Modems i could see my mobile connected in com6.. i have tested the winform application it works fine.Is this the answer? ASP.NET pages are supposed to work.What is happening over here is that when you click on open_com button, the ASP.NET page posts back to itself, executes the event handler i.e., opensthe port. Then when the page finishesprocessing the post back, it is unloaded. At this point the COM1 objects is also destroyed.

I have a parameter page in asp.net consisting of many parameters. I am using ajax and filtering the values of the parameters based on the hierarchy. For example, only those branchs appear of a department if a single department is selectd on the listbox.
I also have a link button on my parameter screen which opens a popup window with a listbox in it. On the popup window, i select some listitems which i pass through the session into parent page when the popup window is closed. Till now, my popup window gets all the values from the data source to fill the listbox.
What i want now is to show only the filtered values on the popup window based on the selections made on the parent pages' parameters.
Page2 having Button 2 and an ascx control UC1. UC1 has a Button 3. Page2 is a modal dialog ( window.showModalDialog )
on Click of Button1 open Page2(modal dialog).
Page2 has UC1. UC1 has a button B3. On click of B3,instead of directly going to B3_click event, another post back happens. Thereafter opens login.aspx in another browser ( It is losing Session containing UserDetails as well as other session details).
now even If I continue entering Username and password, page2 reloads again in the new browser.
I am totally lost.
1) I do not know why UC1 button click makes another postback and thereafter opens up into another page losing all the sessions!!
I want to retain teh sessions till i go back to page1.
