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#

gopi

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

I re-queried the DB again in button click event and bind the data.

and you still have the issue ? What is the issue then ?

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.

Hi! the issue is. I have a grid A which populate when selected index of parent grid B is changed.
In Grid A i have button template "Remove" which should remove the records. well for now it removes the record from DB but i need to again change the index of grid B to show updated record in a grid. so my issue is how could i display updated record in grid A right after I click remove.

cheers.

Hi everybody.
I have this porcion and i want ,from the onclick event, to get a simple string that is in the first column of the clicked row, in the gridview

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
e.Row.Attributes["OnClick"] = ClientScript.GetPostBackClientHyperlink(this.GridView1, "Select$" + e.Row.RowIndex.ToString();
string thefirstvalue = <---- what here to get the value?
}
maybe another way to get a value from gridview? Confused | :confused:

please help me.
thanks

I would suspect what you need to do, is to put the value in your event args, instead of hte index.

Let's say I have a products list, click in a select field of the GridView and i want the near product of the near column
Select productname
Select productname
Select productname
I have the index of the clicked row whit the posted method, but how I get the productname of that row?
please.
Thanks.

If you have the index, you get the data from the datasource, I guess. But, if you have the data already when you write the code, it seems more sensible to pass the data back, while you have it. The onitemdatabound event would then be the best place to write the code that passes the value back ( I'd probably just pass it on the URL, if it was me )

the index of the gridview is not the index in the DB, this productname is the primary key, so i want it.
The onitemdatabound is not one of the attributes of my GridView.
maybe somehow from onrowdatabound?
thank you very much for your help.

Yeah, that's what I meant.

Hi all,

I would like to know whether it is possible to reload a page within an asp:UpdatePanel, or can one only reload the values of certain components?

Many thanks in advance

I'm not sure if this is on the lines you are looking for but maybe have a look at ajax as that does postbacks without refrshing the entire page
hope this helps
