hello every one...
i can use label and textbox in javascript, and now, i am using session, but can not detect in javascript.
my javascript:
function DisplayConfirmation(cost,textboxid)
{
var s=document.getElementById(textboxid).value;
if(s>cost)
{
if(confirm('Are u sure'))
{
document.getElementById('<%=HiddenField1.ClientID%>').value = "true"
}
else
{
document.getElementById("<%=HiddenField1.ClientID%>").value = 'false'
}
}
else
{
}
}
my code in vb:
Protected Sub FormView2_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView2.DataBound
If Page.IsPostBack = True Then
Dim t2 As TextBox = TryCast(FormView2.FindControl("tes"), TextBox)
Dim l1 As Label = TryCast(FormView2.FindControl("costLabel"), Label)
Dim b As Button = TryCast(Me.FormView2.FindControl("button1"), Button)
b.Attributes.Add("onclick", "return DisplayConfirmation(" & l1.Text & ",'" & t2.ClientID & "')")
End If
End Sub
the label and textbox can detect in javascript...
but if i use session, it can not detect in javascript. i don't know about the true code...
my code use session like this:
Protected Sub FormView2_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles FormView2.DataBound
If Page.IsPostBack = True Then
Dim t2 As TextBox = TryCast(FormView2.FindControl("tes"), TextBox)
Dim l1 As Label = TryCast(FormView2.FindControl("costLabel"), Label)
Dim b As Button = TryCast(Me.FormView2.FindControl("button1"), Button)
Session("l") = l1
b.Attributes.Add("onclick", "return DisplayConfirmation(" & Session("l").tostring & ",'" & t2.ClientID & "')")
End If
End Sub
it can not detect...
what should i change it?
thx..

Keep watching. I wouldn't get surprised if his next query would be how to create a web server in Internet Explorer and run a JavaScript webpage in IIS?

How can i iterate through and modify the data in databround rows of a ListView similar to a Gridview?
Here is the Gridview version:
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
Dim i As Integer
Dim Str As String
For i = 0 To Me.GridView1.Rows.Count - 1
Dim objUtil As New Utility
Dim s As String = Me.GridView1.Rows(i).Cells(1).Text
Str = objUtil.SQLdecode(s)
Me.GridView1.Rows(i).Cells(1).Text = Str
Next
End Sub
What would be the ListView version? The purpose as you can see is so I can use my sqldecode function to parse out the characters that represent apostrophe's.

This is bad practice. It leaves your code open to SQL injection attacks. You should use stored procedures for all CRUD operations. Using stored procedures has the added advantage that you don't need to double up quotes in alphanumeric parameter values.

How can it be bad practice, my function disallows any sql injection attacks by pure nature by removing "'"'s. Observe:
<system.componentmodel.dataobjectmethodattribute _<br="" mode="hold"> (System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function SQLencode(ByVal txt As String, Optional ByVal brEncode As Boolean = False) As String
If txt <> "" Then
Dim mySQL As String
mySQL = Replace(txt, "'", "")
If brEncode = True Then
mySQL = Replace(mySQL, vbCrLf, "
")
End If
SQLencode = mySQL
Else
SQLencode = ""
End If
End Function 'SQLencode
<system.componentmodel.dataobjectmethodattribute _<br="" mode="hold"> (System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function SQLdecode(ByVal txt As String, Optional ByVal brToVbCrlf As Boolean = False) As String
If txt <> "" Then
Dim mySQL As String
mySQL = Replace(txt, "", "'")
If brToVbCrlf = True Then
mySQL = Replace(mySQL, "
", vbCrLf)
End If
SQLdecode = mySQL
Else
SQLdecode = ""
End If
End Function 'SQLdecode
Now do you think it's bad practice?

Yes. Of course it is. How does removing apostrophes prevent SQL injection attacks? I suggest you read up on the issue[^] and the consequences for your application.
BTW, your code is really ugly. As I previously mentioned, you can sidestep the whole problem by using parameterized stored procedures.

Hi,
Suppose I am running 3 websites on one client. They have different home pages. How server differentiate the 3 websites and also from where they can be accessible.
Thanks,

The websites would exist in separate virtual directories in IIS.

If we want to access perticular website then how can we know?
whether by ip address or
domain name? or
anything something different.

When you type a domain name, the DNS server (often shortly called as Name Server) looks up its associated IP Address and gives it to your web browser. YOur browser or its associated Proxy server (on your browser's behalf) initiates a HTTP or HTTPS (SSL/TLS) connection with the server. This goes through a number of hops like your ISP, Caching servers etc. But I hope, this can give you a quick insight into what is going on in the background.

So you have multiple Web sites running on your server. One way to do it is to just use different ports. The default port is 80. So if you type www.mywebsite.com:80 is the same thing as www.mywebsite.com. You can add a website in IIS at port 81 so you would type www.mywebsite.com:81.
That is not really a good way to do it since most users will never type the 81. A better way is to give each site it's own IP. So you need to give you server multiple IP's. The assign each individual IP to the website in IIS. You can then DNS each IP to a different name like web1.mywebsite.com and web2.mywebsite.com.

Hi;
I have tried to add a third gridview to my version of this code (See Editable Nested Gridview article on this site) but I still have some questions about the code.
Such as <ItemTemplate><br />
<a href="javascript:expandcollapse2('div<%# Eval("Institution") %>', 'one');"><br />
<img id="imgdiv<%# Eval("Institution") %>" alt="Click to show/hide Overdraft Summaries for Institution Types <%# Eval("Institution") %>"<br />
border="0" src="plus.gif" width="9px" /><br />
</a><br />
</ItemTemplate>
What is the meaning of the 'one' string used in the expandcollaspe2() call ?
I know that the expected value is row ? Current row ?
Here is the function :
function expandcollapse2(obj,row)<br />
{<br />
var div = document.getElementById(obj);<br />
var img = document.getElementById('img' + obj);<br />
<br />
if (div.style.display == "none")<br />
{<br />
div.style.display = "block";<br />
if (row == 'alt')<br />
{<br />
img.src = "minus.gif";<br />
}<br />
else<br />
{<br />
img.src = "minus.gif";<br />
}<br />
img.alt = "Close to view other Institutions";<br />
}<br />
else<br />
{<br />
div.style.display = "none";<br />
if (row == 'alt')<br />
{<br />
img.src = "plus.gif";<br />
}<br />
else<br />
{<br />
img.src = "plus.gif";<br />
}<br />
img.alt = "Expand to show Institutions";<br />
}<br />
}
And finally when I try to all a third DVG I am not getting it to display. I have taken care to repeat the code sequence done to get the second grid to display, which it does.
So for grid 3 I create a template column in grid2 like so:
<br />
<asp:TemplateField><br />
<ItemTemplate><br />
<tr><br />
<td colspan="100%"><br />
<div id="div<%# Eval("typeName") %>" style="display: none; position: relative; left: 15px;<br />
overflow: auto; width: 92%"><br />
<asp:GridView ID="GridView3" AllowPaging="True" AllowSorting="true" BackColor="White" , ETC.<br />
IN MY CODE BEHIND I SETUP MY FUNCTION TO RETURN A DATASET:
Private Function ChildDataSource2(ByVal strInstitution As String, ByVal strTypeName As String, ByVal strSort As String) As AccessDataSource<br />
<br />
Dim strQRY2 As String = ""<br />
Dim dsTemp2 As AccessDataSource = New AccessDataSource()<br />
dsTemp2.DataFile = "App_Data/aGreatDB.mdb"<br />
<br />
strQRY2 = "SELECT Institution, AcctNum, AcctName, ODDate, [Rundate]-[ODDate] As DaysOverdrawn, CurrentOD, OFFICERS_NAME, OFFICER_CODE, " _<br />
& "Income, Principle, NetOD AS COB_OD, TypeName FROM qryDetail2 WHERE Institution = '" & strInstitution & "' AND TypeName = '" & strTypeName & "' " + strSort<br />
<br />
dsTemp2.SelectCommand = strQRY2<br />
Return dsTemp2<br />
<br />
End Function<br />
I also have a question about where this function should be called. Do I call this in Gridview1.ROWDATABOUND or in GRIDVIEW2.ROWDATABOUND ?
This is my code to call the dataset function:
Dim gv2 As GridView = New GridView()<br />
gv2 = row.FindControl("GridView3")<br />
<br />
' 'Expand the Child grid<br />
ClientScript.RegisterStartupScript(Me.GetType(), "Expand", "<script language="javascript">expandcollapse2('div" + e.Row.DataItem("Institution").ToString() + "','one');</script>")<br />
End If<br />
<br />
'Prepare the query for Child GridView by passing the Institution of the parent row<br />
gv2.DataSource = ChildDataSource2(e.Row.DataItem("Institution").ToString(), e.Row.DataItem("TypeName").ToString(), strSort)<br />
gv2.DataBind()
If my function is expecting two PARMS is this correct syntax for the e.Row.DataItem method call ?
Sorry if I have exceeded my in message code limit.
Thanks for any suggestions or insights !

i need to let the user see some of the data in a table that contains lots of records and when he scroll down the other valus appear
ex: i have more then 200000 record i want the user to see only 1000 and when he scroll down he will see the other 1000 and so on not forgetting that no need for the control to load the whole 200000 record only 1000 per scrol...
thanks

You could do this using AJAX.
No one is going to write your code for you though. You'll have to do this yourself.

Hi friends,
I am using MS.net 2.0 and MSSQL2000.
I have some doubt regarding automatic alert messages.
I have 3 users like U1,U2,U3.
When U1 submit (insert) a data into the database, an alert message will show to U2 and U3.
Be thankful for any suggestion...
They laugh at me; they think I’m different. I laugh at them, ‘coz they are all same!!

you can use Trigger for that
|
|
|
|
|
Well, you could use a trigger, but that's rather pointless as the web application already knows when it's inserting something. The trigger could only update something in the database that the other clients could poll for, and the web application can do that by itself without a trigger.
Experience is the sum of all the mistakes you have done.

|
|

The HTTP protocol doesn't support sending anything from the server to the client. All communication is initiated by the client, so the browser has to poll the server at a regular interval if you want the client to be aware of anything that happens on the server.
Experience is the sum of all the mistakes you have done.
