Hello friends,
I want to transfer some data from one form to another form.
But i don't want to use session or querystring.
Is there any other way to transfer tha data.

you can use Hidden field.

Why is it that I keep answering this same question lately ?
Create your two pages as controls, and show them both on the one page. Then viewstate will hold the data for you, your main page just has to move the data between the pages as it shows/hides them.

They don't relate to your computer, they relate to your ISP. Check Out look, they will be in there, or you wouldn't be able to check your mail.

Hi,
I have a DLL with some win controls in it that i am embedding in a ASP.NET page. However, when ever i want to select from the database i get OleDbPermission exceptions even after i've done: Demand(); or Assert();
Is there a simple way of just telling IE to just trust the DLL and ignore all the security issues since this is a personal project and will only ever be run on my computer.
Regards,
Gareth.

I am having a grid and it contains two columns. The First Column contains one Image and the second column contains table and in the first row of the table i have a Link button like this :
<asp:linkbutton text="">]]>' runat="server" ID="BookTitle">
And i want to invoke an event during onclick event of this link button.
Also if i use onSelected_IndexChanged event in grid view like :
public void GridView1_OnSelectedIndexChanged(object sender,EventArgs e)
{
e.-----------
}
This event is not occuring.
I am working on 2.0 gridview.What should i do to invoke the event .Where i am wrong.
Can anybody helpme

The LinkButton should have a CommandArgument as "Select". This would trigger the SelectedIndexChanged event. Have you noticed it?

I'm using the following to insert a record in my DB;
protected void submitButton_Click(object sender, EventArgs e)
{
DataSet2TableAdapters.guestsTableAdapter adapter = new DataSet2TableAdapters.guestsTableAdapter();
adapter.Insert(nameTextBox.Text, messageTextBox.Text);
adapter.Dispose();
}
And it succeeds in the insert but the page doesn't show the new data but, if I go to another
page and come back it shows up.
So my question is how do I update the page where I'm doing the INSERT after I do the insert.
Much obliged,
Mike

The order is page load, then events, then page prerender. I'd say you're loading your data in page load, before the event fires to add the new record.

Christian,
Thanks that makes sense. Would it make any sense to reload (?fill?) in the prerender stage?
Thanks
Mike

I think Rebinding the datasource after the insert will solve the issue.

Thanks for the advice I got it to work by overriding the Page's OnPreRender method!
Works like a charm!

It's not possible. ASP.NET is not built for that.

I have an application that I would like to show different login pages based on the client or url. I have the roles and members setup and I have a default value for the loginurl parameter in the web.config. I would like to intercept this before the page redirects to login.aspx and be able to define the loginurl or use the FormsAuthentication.RedirectToLoginPage() method. Where is the best way to do this?
Also I am using a basepage for all of my pages.

As you can see the errorcode is an OUT parameter, value would be in the 3rd parameter. You can get it like
cmd.Parameters[2].Value

I'm using a DataList to present a list of TextBox - RadioButton pairs. Now I don't want to go through the whole thing of putting a row into edit mode etc. I want to do a client side Ajax postback when the RadioButton is clicked, or on blur of the textbox. How do I get the parent row of these controls? I need this to store an ID attribute so I can specify which record to update during the Ajax call.
I've thought of using an invisible column with the ID, but I need to know how to access the parent of the control causing the event, then access its cells collection, then get back to the ID value.

When i developed application in asp.net i have used differnt validators.The question is if i use Example:textbox shd not be blank
I have used one requiredfieldvalidator
and in code behind like in
if
isdbnull(txt.text) or txt.text=""
msgbox("blank")
elseif....
end if
if i use both validators as well as validators it that cause application performance??
thistype of code occurs many times in the application.So please can any body give some answer.
And also "autopostback=true" property of some controls makes the server hits more.So at the user end appln becomes slow.What to do for this??But i have to set that property as per appln concern.
Please respond somebody for this question.

IF you are using required field validator for the textbox then i think there is no need of checking the textbox is empty or not .....
Do validations only once client side or server side (depends on the security of data).
Kissy16 wrote: But i have to set that property as per appln concern
As you said you need to change the things upon user interaction.
First question is that could you use javascript for the same ?
If yes then you can have some javascript function that will do the things that you are doing by postbacking the whole page ...
Another way AJAX but it is not going to make drastic changes.
So main conclusion is what you are doing at server side could you perform it at client side using javascript ?
Thanks and Regards

This is incorrect. In ASP.NET you can't display a message box as you do in windows applications. IsDbNull checks whether the value belongs to System.DbNull type. So you can't check the text box string in such a way.
When you use validators, always check the Page.IsValid property to make sure all validators are validated successfully.
If(Page.IsValid) Then
'Do your stuff
End If

It will hit in the browser. You can't avoid that. But if you need to avoid page getting refreshed, use AJAX. But AJAX request also hits server. Also I don't think that it will be a big performance problem.
