hi all iam using a javascript file referenced inside a page. In this script iam referencing a JS function found inside the page. It is generating an error."The Controls collection cannot be modified because the control contains code blocks (i.e. )."
the code is as follows
External JS:
var ok =false
....some code
if (!answer)
{
ok=false;
CloseOnOk();
}
where CloseOnOk is a javascript function found on the page
function CloseOnOk()
{
if (ok==true)
GetRadWindow().Close();
else if (ok==false)
{
var txthidden=document.getElementById('<%=txtHidden.ClientID %>');
txthidden.value='1';
}
}
iam also referencing the external javascript from the page
<script language="javascript" type="text/javascript" src="../../Scripts/Confirmation.js"></script>
Any ideas??

|
|
Its not clear which piece of code is throwing the error but you can try commenting out the GetRadWindow().Close(); line to see if that is the problem.
Also try changing txthidden.value='1'; to txthidden.innerHTML='1';.
|
|
|
|
|
The error appears on the ecternal JS line where iam calling CloseOnOk();
it is not calling this function.

The error message is very clear enough. You can't use session in this event as it's not instantiated. Application_AuthenticateRequest is in the early stage of ASP.NET page life cycle. AcquireRequestState is the event where session will be created. So choose any event that fires after AcquireRequestState.

Hi!
I used Win XP Pro to develop an ASP.NET application. Everything is working fine in Win XP Pro. I published/deployed the same application into the Win Server 2003 Standard Edition. The website loads correctly, but I am not able to insert/update/delete data.
I have enabled Named Pipes and TCP/IP.
No errors are shown. The page just refreshes after I click the submit button without showing the new updates.
Hope someone can help me with this prob!
Thanks in advance.

I don't think it is possible to embed images this way for web based email clients.
Your best option is to find a way of getting your images onto a public website and linking to them from there.

Hi to everyone,
a stupid question:
I added an Ajax control to Visual web Developer, adding a reference to the .dll compiled file in the project..
Now I'd like to use it, but I can't declare it in the asp.net page...
I also would like to add it to the toolbox..How could I do this?
Thanks!
Bye
|
|
|
|

I'm don't use "Visual Web Developer" but try right-clicking on the toolbox and if there is an option called "Choose Items.." then you can browse to the dll of the control and this will add it to the toolbox.

i have a question regarding the id of link button .
I am placing the link button in a gridview,
Can anyone suggest me the way to do this?
Thanks

gridviews have rows, rows have cells and cells have your controls. do somethin like this and see what happens
LinkButton lnk =(LinkButton)gv1.Rows.Cells[Index].FindControl("LinkButtonID");

I've got some DataList control on a page to display some images after Thumbnail Photo Browsers articles at codeproj. But how to add SelectedItemTemplate to the page so I can click the image in the control and get DataList1_SelectedIndexChanged event to handle?
That does not work at selecting items?
<asp:datalist id="DataList1" runat="server" height="49px">
onitemdatabound="DataList1_ItemDataBound"
onselectedindexchanged="DataList1_SelectedIndexChanged" RepeatColumns="5"
RepeatDirection="Horizontal" Width="52px">
<selecteditemstyle bordercolor="#CC3300" borderstyle="Double">
<itemtemplate>
<selecteditemtemplate>
<asp:button id="Button1" runat="server" commandname="select">

Hi,
I have two dropdowns.
I want that the DDL2 gets populated based on the values in DDL1.
How can I achieve that.
This is the way I am populating DDL1
string cmd = "Select * from abc ";
SqlDataAdapter da = new SqlDataAdapter(cmd, connection);
DataSet ds = new DataSet();
da.Fill(ds);
DropDownList1.DataSource = ds;
DropDownList1.DataTextField = "Name";
DropDownList1.DataValueField = "Code";
DropDownList1.DataBind();
DropDownList1.Items.Insert(0, "--Select--");
|

|
|

Hi,
On selectedIndexChanged even of DDL1 pass the value of selection and retrieve the result based on passed value to bind the DDL2.
Regards

First bound data to your linkbutton in datalist .
then use this coding for ur click event for link button
if(e.commandName == "lnkbutton")
{
sqlconnection open();
string name = ((LinkButton)e.Item.Cells[0].Controls[0]).Text;
}
//pass name to query to fetch data
// mention your link button column no. in cells[] item.

I am using the following code
if (System.IO.Directory.Exists(Server .MapPath ("Albums/username" ))
{
System.IO.Directory.Delete(Server .MapPath ("Albums/username"),true);
}
to delete the folder named "username" and all of its subfolders. After this , if I take the folder Albums, I can see "username" folder. But when I double click on the folder, " Access is denied" message is coming. If I close visual Studio the folder itself is disappearing. In production server how will it work?

I got the answer. If anyone needs the answer here it is!!
My project is stored in a drive which uses NTFS File System and the folder to be deleted is inside my project folder. Since now I have opened this project in Visual Studio, that folder is also being used by Visual Studio.In NTFS, You may not be able to delete a file if the file is being used. You may be able to use the Delete command to delete a file, but the file is not actually deleted until the process that has the file open releases the file.
