I think the event in which you write your code must be raised after page_initialization or page load event
that's why this code doesn't have any affect

Are you able to assign required number of link button to the correct cell ? The code which you supplied doesn't make any sense to me.
|
|

|

Ya , i got it. But can u tell me is there any other Simple way .
And here is my code which worked out. But if this method , i implemented it make be coding conjusted when i have to do some operations on selection of the particular linkbutton.
HTML
--------
<asp:label runat="server" text="Author" forecolor="ButtonShadow" id="AuthorLbl" font-size="Small"><asp:linkbutton id="Lb" runat="server" text="">]]>'>
CodeBehind
-----------
public string Call_Author(string IsbnID)
{
ArrayList AuthorCount = new ArrayList();
DataSet ds;
ds = objAddDL.Call_Author(IsbnID); // Select query to fetch all author names where IsbnId="someruntimevalue";
string AuthorName="";
foreach (DataRow dr in ds.Tables[0].Rows)
{
AuthorName = dr[0].ToString();
AuthorCount.Add(AuthorName);
}
string retval="";
int ACount = AuthorCount.Count;
if (ACount == 1)
{
retval = "" + AuthorCount[0].ToString() + "";
AuthorCount.Clear();
}
if (ACount == 2)
{
retval = "" + AuthorCount[0].ToString() + "" + " , ";
retval += "" + AuthorCount[1].ToString() + "";
AuthorCount.Clear();
}
if (ACount == 3)
{
retval = "" + AuthorCount[0].ToString() + "" + " , ";

If i open an browser it as to asks username and password.if it correct then only it has to open.how to do it in asp.net using c#

You can't. You can make your SITE work that way, but not the whole browser. If you mean the former, then there's tons of info on the web on how to do that using your own system or the built in ones. If you mean the latter, then you have no idea how ASP.NET works, or what it is, and should do some reading on the topic.

i think you may be able to set it up so that if you enter the wrong username and password then ie will close but I don't think you can achieve what els you were saying

Perhaps an IE add in could do that, but ASP.NET cannot stop you going to another page.

Dear All,
I sent a HTTP request to a ASP.NET page, which including Tradition Chinese character. Such as:
http:\\www.mydomainname.com\myfolder\mypage?lastname=?
(The URL is in utf-8 encoding should be)
and then I cannot get the traditional Chinese character properly with the page of ASP.NET C# in server side. Such as:
this.m_strLastNameIn = Request.QueryString["lastname"];
then the value of m_strLastNameIn become: ??
The HTTP GET Request is sent by my MFC C++ WIN32 application with utf-8 URL with URLDownloadToFile() function. Such as:
URLDownloadToFile(NULL, wszURL, wszStoragePath, 0, 0)
where wszStoragePath is wchar_t[1024] under C++;
How can I solve this problem?
I want to get the traditional Chinese character properly at ASP.NET C# page.

Whoah!! What is this... I've created a web-application which runs on 144 seperate websites. Those websites are pretty equal and therefore pointing to the same Home Directory (local path). The app. is written in asp.net 2.0 and uses SQL Server 2005 as data source.
We're test running the app since a month or so and depending on the server load, the following exception occurs in about four days of running :
Failed to initialize the AppDomain:/LM/W3SVC/1993985091/Root
Exception: System.SystemException
Message: Failed to create AppDomain.
StackTrace: at System.Web.Hosting.ApplicationManager.CreateAppDomainWithHostingEnvironment(String appId, IApplicationHost appHost, HostingEnvironmentParameters hostingParameters)
at System.Web.Hosting.ApplicationManager.CreateAppDomainWithHostingEnvironmentAndReportErrors(String appId, IApplicationHost appHost, HostingEnvironmentParameters hostingParameters)
InnerException: System.OutOfMemoryException
Message: Exception of type 'System.OutOfMemoryException' was thrown.
StackTrace: at System.AppDomain.nCreateDomain(String friendlyName, AppDomainSetup setup, Evidence providedSecurityInfo, Evidence creatorsSecurityInfo, IntPtr parentSecurityDescriptor)
at System.AppDomain.CreateDomain(String friendlyName, Evidence securityInfo, AppDomainSetup info)
at System.Web.Hosting.ApplicationManager.CreateAppDomainWithHostingEnvironment(String appId, IApplicationHost appHost, HostingEnvironmentParameters hostingParameters)
I've been trying to find the cause of this excepion but cannot find any reason why this exception occurs. I've been looking for memory leaks since there's obviously a memory problem... The websites are pretty frequently visited so we expect a large amount of traffic. Anyway, i'm pretty much determined to get the cause of this exception, but i'm quite stuck here...
Any suggestions?

i have 3 gridview
on selected index change of first gridview(company), I populate second gridview(users) on second gridview selected index change i display a list of jobs that are available (in a listview) and list of jobs assigned (in gridview) and roles associated with that job (checkbox in a 3rd gridview)
when i need to assign a job to the user i simply do followings
1. click company from 1st gridview
2. click user from 2nd gridivew
3.select a property from available property
and click a button that adds a new record in the assigned gridview but i want to display the newly added row as soon as they hit assign button. i need to reselect the user to see the updated change. is there anyway i could achieve this without using session?
please advise.

Oh, you were crossposting. I see. Please don't do that.
If you want to update without postback, it has nothing to do with the session, it has to do with AJAX.

Hi Chris
you have mentioned using either URL parameter or view state. now i cant use URL parameter as its a requirement.
here are few codes to help u understand.
Private Sub gvUsers_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles gvUsers.SelectedIndexChanged
dsAssignedPropertyList = mydal.SecurityGetAssignedPropertyByUser(domainid, CompId, userid)
If Not dsAssignedPropertyList Is Nothing Then
gvAssignedProperty.DataSource = dsAssignedPropertyList
gvAssignedProperty.DataBind()
end sub
Protected Sub btnAssign_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAssign.Click
Dim myDAL As New clsDAL
Dim result As Boolean = False
userid = CInt(lblUserId.Text)
propertyid = lbAvailableProperty.SelectedValue
result = myDAL.SecurityAssignProperty(userid, propertyid)
If result Then
lblMsg.Text = "updated"
Else
lblMsg.Text = "failed"
End If
End Sub
In first method i am populating gvAssignedProperty and in second method i managed to insert the record and display a message but i really want to show the added record in a grid. could you please help?
thanks

So you're doing postbacks here, you said you wanted to avoid that ?
Is the issue that your postback adds a record but it's not visible when the postback ends ? You should be reading your datasource and databinding after you insert the record, or, in your prerender method. It depends on if you want to bind every time to save viewstate, or use viewstate to store records and save DB resources.
