PDF is read only file, moreover it can't contain controls like TextBox.

Landscape printing orientation

Hi,

I want the users of my website to be able to print a datagrid on one of the webpages. Now my problem is that when the user does so one of the columns is cut off due to the page orientation. But if I set the page orientation to landscape manually it prints the entire datagrid.

How do I set the page orientation to Landscape programatically.

Is there some way I could achieve this using the CSS file?

Thanks in advance,
Avesh

ASP.NET don't have any handle in printing. It's completely browser depended. What you can do is re arrange the grid to fit for printing.

Application Session Object and Web Services

From what I can gather, since a web service is stateless, then I cannot use global.asax in a web service to store application variables. For example, in classic asp, I could do the following...
-->
Sub Application_OnStart
set g_pcmsrv=Server.CreateObject("PCMServer.PCMServer")
set application("g_pcmsrv") = g_pcmsrv
End Sub
<--
With the above example, I can see and use g_pcmsrv anywhere in the web app.
But the same will not work in a web service....
<--
Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
' Code that runs on application startup
Dim g_pcmsrv As Object = Server.CreateObject("PCMServer.PCMServer")
Application("g_pcmsrv") = g_pcmsrv
End Sub
-->
With the above, I get a 'object not set to a reference' error.
Does anyone know a workaround?
Thanks VM

Why don't you use the Repeater control? You can define the template and add controls to it.

One at a time ? If you give an example of what you mean, perhaps we can help. If it's a comma seperated list, just use the Split function to turn into a string array. USe int.tryparse if you want them to come out as ints instead of strings.

That's because you are writing out the code before the code of the page. That makes the browser ignore the doctype tag and render the page in quirks mode.

Use the Page.ClientScript.RegisterStartupScript method to put the script in the page.

Either check for the id before you add the record, or handle the exception that is the result of trying to add a duplicate id.

Readonly Gridview

I have one form. When I took the Form to ReadOnly state all the controls in the form are need to be in readonly,
A) I have Gridview. How to make this Gridview to ReadOnly. Currently I am doing the gridview.enabled = false. It greyed out the gridview.
B) And I have some validation controls, I want to supress that validations when the form is in Readonly.
Thanks

Re: Readonly Gridview

A) You have to Navigate through the control Collection of the Gridview and set the property to Read-Only/ENABLED-False.

B) You have to set the Enabled property of the validation controls to false. Page has GetValidators("group") method. Check whether this helps you in some way to disable all the validation controls at once, since it returns the validators to the ValidatorCollection object.

Database doesn't have rows. Only tables in the Database can contain Row's. what is that you are trying to do exactly in that code?
I have sent you a link to Read the Basic's of SQL Command. If you go through it you will understand how to write a UPDATE statement in SQL.

Here is the syntax of the UPDATE statement used to make changes to the existing records in table.

update tablename<br />
set columnname = newvalue [,columnxname = newvaluex...]<br />
where columnname OPERATOR value [and|or columnnamex OPERATOR valuex]

Compare this syntax with your UPDATE statement and check whether you have given it right.

I think having the ViewState Enabled for ur control should solve this problem
try having the EnableViewState=true in ur FormView

or save that record in the session and take it back on return

I hope it helps
