On my machine, I have set "script and executable".
Also, try to attach to the process (aspnet_wp).
One more thought: check permissions for you website

Just incase any one stumbles upon this with the same problem - here is how i fixed it.

in IIS->directory for the site i ticked a checkbox script source access and applied it to all child nodes. This did work but every now and then needs undoing and redoing.

Not sure why this worked nor am i sure of the consequences of checking the box so you may want to look into that before blindly following my advice (as it is rarely any good)

Is there a way to check that a Session variable exists without using try/catch?

Is there a nice easy way to check Session["x"] exists without trying and catching it?

Thanks.

no need to use try catch for that they are there for different purpose.
You can check the session like this:

if(Session["x"]!=null)<br />
{<br />
//do your work.<br />
}

Imagine the key has not been added on the session at all, that time do we need to user only try...catch block or is there any other way will work?

That is what you need to check. If you will use the session variable without assigning it then it will thow the exception exactly what you got.
So prior to use that you have to check whether that is available or not like this:

if(Session["x"]!=null)<br />
{<br />
//do your work.<br />
}

here x is the variable name you change it with yours one. Smile | :)

Printing from a website (ASP & JavaScript)

Hi,

I have an ASP page that draws up a report and display it to the user. If the user wishes to do so, he can click a "print" button which activates the printer dialog via javascript. This would be the same as if they selected "File > Print" from the browser menu.
My problem is that at hte top of the page, page numbers are added automatically, and at the bottom the URL of the page that was printed. Is there a way to get rid of this extra information, so that a "clean" document can be printed with only the results from the report.

Any help would be appreciated,
Thanks.

There is another dialog to configure the header- and footerline in the Menu "File" -> "Configure page".

After my state of knowledge, there is no way for remote control this dialog box settings. Same statement counts for the printer dialog to configure i.e. the layout of the page.

hi,
Well I can help you with your 1st question,
Your can add this dataset either in Session or ViewState
Example.
ViewState.Add("Name for ViewState",Your dataset name) or
Session.Add("NAme for Session", datasetname)

With this i think solve your problem...

I m sorry for your second question.

Hopes it will work..

Compilation Error "cannot convert from 'ref int' to 'ref int?"

Hi,

I am working with asp.net 2.0. In my project, i am using a Design time DataSet (.xsd file). In TableAdapters i have Added a query which uses my existing Stored Procedure to retreive Data, Which accepts some Arguments. This method is below,

DALTableAdapters.ItemsTableAdapter.GetProductList(int?, int?, int?, int?, ref string, ref string, ref int?)

When i call this method from my Codebehind Class of the page,

DAL.ItemsDataTable items_dt = items.GetProductList(catId, brandId, page, '3', ref catName, ref brandName, ref numProducts);

For all the variables in the argument, i have already assigned some values.

While compiling, I am getting the following Error.

Argument '7': cannot convert from 'ref int' to 'ref int?'

How can i resolve this problem ? Smile | :)

Regards,

Jay

Hi there,
"ref int" and "ref int?" are different, see Nullable types[^], in this case you need to cast the numProducts to a variable of the nullable type int? before calling the method.

Thanks for your most valuable info. Smile | :)

It works fine, when i changed my datatype of numProducts local variable from int to int?

But i am experiencing this problem now only. In my StoredProcedure, i have passed all the parameters like this.

CREATE PROCEDURE GetProductsList<br />
	@CategoryId INT,<br />
        @BrandId INT,<br />
	@PageIndex INT,<br />
	@NumRows INT,	<br />
        @CategoryName nvarchar(50) OUTPUT,<br />
        @BrandName nvarchar(50) OUTPUT,<br />
	@ProductCount INT OUTPUT<br />
<br />
AS<br />
<br />
BEGIN<br />
.........<br />

I am using this SP for SELECT method of my ObjectDataSource.

My doubt is, Why the @ProductCount needs to be declared as int? ? No string? for @BrandName Smile | :)

And WHY all the OUTPUT variables are passed as Reference??

DropDownList problem

Hi all

I have a dropdownlist on my page but it is always showing the value rather than the text. For example:

<asp:DropDownList runat="server" id="filter">
<asp:ListItem value="1">Filter 1</asp:ListItem>
</asp:DropDownList>

This will produce the dropdownlist but the text shown will be 1 rather that filter 1 Confused | :confused:

. This happens when the listitem is declared as follows as well:

<asp:ListItem value="1" text="Filter 1" />

Any ideas on why this is happening??
The project that this page is part of uses nested master pages if this sheds anymore light.

Thanks in advance.

I usually do this in the GridView's RowDataBound event. (Or if you are indeed using a DataGrid instead of the GridView it is the ItemDataBound event. Personally, I don't use the old DataGrid objects anymore.) For a GridView the code would look something like this:

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
    Select Case e.Row.RowType
        Case DataControlRowType.DataRow
            e.Row.Cells(0).Visible = False
    End Select
End Sub

In this example I am hiding the first column in the grid only. If you need to hide another you would need to know the column index and add another statement like this:
e.Row.Cells(index).Visible = False

Hope this helps.

Using ASP.NET 2.0, say I want to store a picture in “C:\Users\user123\images\MyPortrait.jpg” on the server. How can I have the user access it through an aspx page? Because it seems I can only get the Image control to reference a url that is within the Website directory.
