Cascading dropdown not posting back even though autopostback=true?


I have the following code:

<asp:DropDownList ID="ddlCountries" AutoPostBack="true" runat="server">
<cc1:cascadingdropdown ID="cddCountries" runat="server" Category="Country" Enabled="True" LoadingText="loading" PromptText="choose country"
    ServiceMethod="GetCountries" ServicePath="geolocation.asmx" TargetControlID="ddlCountries">

code behind
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
End Sub

Private Sub ShowSearchResults()

End Sub

Why is the ShowSearchResults method not called when I change a value in the ddlCountries dropdown, even though I have autopostback="true" on it.

How to return back to a specific page in a gridview list?

Hello,  I have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10. I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to). Hopefully this code helps to understand what I'm asking: <asp:GridView DataKeyNames="Referral ID" ID="gvList" runat="server" CellPadding="4"     ForeColor="#333333" GridLines="None" OnRowCommand="gvList_RowCommand"     OnRowDataBound="gvList_RowDataBound" OnRowDeleted="gvList_RowDeleted"     OnRowDeleting="gvList_RowDeleting" AllowPaging="True" PageSize="20"     AutoGenerateColumns="False" OnPageIndexChanging="gvList_PageIndexChanging"    OnRowCreated="OnRowCreated" AllowSorting="True" OnSorting="OnSort"> protected void gvList_PageIndexChanging(object sender, GridViewPageEventArgs e)        {   &nb

Cascading drop box holds old value if empty on auto post back

I have 3 drop boxes: 1.) Choose Operation 2.) Choose Site 3.) Choose Area. All three of them are linked to an SQL server database which has 3 tables following the same heiarchy of order. I.e. Areas belong to a Site and Sites belong to an operation. And there can only be one operation per site, or one site per area. First you select an operation, then the page auto postbacks to filter the sites. Then you pick a site and again it autopostbacks to filter the areas. The issue I am having is that when an associated operation has no sites underneight it, and therefore no areas under that, the previous values that were in the boxes are displayed and the user can't click on the boxes anymore. I think this is kind of cheap looking and would like a way to make it so the boxes are clear (i.e. nothin in them). Is there anyway to check if they are going to freeze like that and assign them blank values??Any suggestions on this issue would be greatly appreciated!-Jordan

how to make a back up file(.bak) of database


I need to make a back up file(.bak) from my database (.mdf)

I learned that i need to use Ms SQL Server management studio express. I can't figure out how to connect to the database. looks like I need to select a server type, but nothing comes up for me to select.

Getting error message and other data back from SSIS to managed code




From a SharePoint workflow we are trying to synchronously execute an SSIS package - which seems to work - and display error messages and return some variables back to SharePoint.


I followed the "Running a Package Remotely by Calling a Remote Component or Service" instructions on http://msdn.microsoft.com/en-us/library/ms403355.aspx and executing and parameterizing the package does not seem to be a problem. But the SSIS package does a lot of plausibility checking and raises an error (RAISERROR in T-SQL or Error

How to get a mdf file back from sql files recovered from SQL Recovery Toolbox?



I had a corrupted mdf file so I purchsed SQL Recovery Toolbox to fix it. When it repaired the file, it spat out a number of sql files and an install.bat file. Because the file was a sql 2008 express file, i'm supposed to now use sqlcmd.exe to fix it. Apparently to get it back to a mdf file, I need to create a blank database and somehow use sqlcmd.exe to import the sql files into the new mdf file.

I use a security program which installs sql express 2008 during the install. I don't know how to use MS Sql. The security program I use has it's own batch file to attach or detatch the two mdf and ldf file to it. I emailed the SQL Recovery Toolbox tech support for instructions on how to created a new mdf db and import the repaired sql files but they basically said that they have an agreement with MS and cannot tell me how to do it.

Can someone please let me know what to do or where to look for assistance? I am stuck at the moment and don't know what else to do.

Any help greatly appreciated, cheers.

Is it possible to convert WSDL file back to Service Contract Interface for hosting? (WCF)


Hi there,

I would like to convert WSDL file to Service Contract Interface for hosting purposes. I know there is an option  to create proxy classes for clients using SVCUtil.exe or WSDL.exe. But this is not i would like to do.

I have a situation where, one of our clients have already hosted webservice. And I need to host a similar webservice. so to do it I must hand craft whole service contract Interface from the scratch. So without writing from the start can I use the existing WSDL to create the service contract Interface and the implementation class automatically with some tool?



How do I get the file "SQLServerManager10.msc" back ?


My computer's OS is Vista SP2

Is the file "SQLServerManager10.msc" is a native file of Win Vista ?

Or dose it come into my PC with the installation of SQL Sever 2008 express ?

I installed visual basic 2010 express into my pc and it would force me also to install SQL 2008 express in the same time. When I tried to uninstall all relared softwares to VB 2010 express, I failed on uninstalling SQL 2008 express. When I checked my file system to make sure all sql-related files has been deleted, I find the file "SQLServerManager10.msc" still lived under C:\Windows\system32\. Because I thought the file maybe a residue of sql 2008 express, so I deleted it. But later when I installed SQL Sever 2008 R2 express with Advanced Services along, I found the file "SQLServerManager10.msc" did not come back...

How do I get the file "SQLServerManager10.msc" back ?

Post back puzzle


Hi, I have a website where the user makes a selection from a combo box and it then fills a couple text boxes with text based upon the selection. I'm sure as you know it could take a second for the text to appear in the text box due to the post back. I know there is no way to make it instantanious, so what I would like to do it fill the text box with somthing like "Loading Info..." so the user does not type in it while the information is loading.

If you would like to see what I mean please go to this page: www.epiclinks.com/create.aspx and mess around with the combo boxes and You'll see what I mean.

What I would like to do is have it do a post back to write "Loading Info..." and then do another post back to fill it in based upon their selection. How would I do this?

I'm up for anything, so if you have a better solution than that please let me know.

Here is the page directive for the page that throws the error:

@ Page language="c#" Inherits="University.AspNet.Index" CodeFile="Index.aspx.cs" %>

The code behind file Index.aspx.cs starts like this:

using University.Framework.UI;

namespace University.AspNet

public partial class Index : University.Framework.UI.HomePage

The code behind is extending this HomePage class, which is in turn an extenstion of another class University.Framework.UI.Page, which extends the System.Web.UI.Page class.
