The right way is to request 200 records to begin with.

I am not aware of a way, but that's because I'd never try to write such horrible code. I'd fix the problem at the source.

Data Transfer / Multiple pages.

Hi I have five pages.

A B C D E;

A calls B calls C. (via buttons on respective pages)
also
A calls D calls E. (via buttons on respective pages)

A shows 2 values B1 & C1 (Both empty at start)
A shows 2 more values D1 & E1 (Both empty at start)

Notes.
To get to C the user first presses Bbutton then when in B presses the CButton.
When In C a user enters some data in text box C1 and returns to B.
When In B C1 should be displayed. Also the user enters some more information B1 and returns to A
When back at A, when page B returns A should update and show B1 & C1

To get to E the user first presses Dbutton then when in D presses the EButton.
When In E a user enters some data in text box E1 and returns to D.
When In D E1 should be displayed. Also the user enters some more information D1 and returns to A
When back at A, when page D returns A should update and show B1 & C1

Could any seasoned professional please suggest how they would approach this.

How do you exit a page and return to the calling page ?

My preferred approach is using properties set/get. However how do you refresh relevent fields when a page returns?

The right way, is to make pages 1-5 all controls, put them all on the same page, and then you can use viewstate to store values and pass them between 'pages'

Are you a winforms programmer? Designing web pages like this will be a burden to the end user. You can use session variables, query strings or cross page posting to pass data one form to another.

How to stop text_changed event on a particular button click

amittinku5-Oct-09 21:53

Hi,

There are some text boxes , one "back" and one "reset" button on screen.
One text box is employee id. After entering employee id, it populates the rest details in other text boxes. This code is written in text_changed event. it works fine.

Issue is with following scenario:

Suppose I enter emp id in text box and directly jump to Back button and click it. Now text_changed event take place, rest of details will be populated, we will not go to back page. We will have to reclick back button to go back. Same holds true for reset.

So how to avoid this i.e. data should not be populated when we directly jump from text box to back button, should go to back page. same for reset button.

I let u know about a simple reproducable code.
Drag an asp text box control.
Drag an HTML button control.

Make the autopost back of textbox=TRUE
protected void TextBox2_TextChanged(object sender, EventArgs e)
      {

            Response.Write("hi");
      }

function Button1_onclick() {
alert('clicked button');
}

Run it. Enter any text in text box and click on button. Button will display "hi", it will not trigger its own event. So I want that on button click, TextBox2_TextChanged event should not take place. IN any other condition, it shold work fine.

Well, that sucks. Anyone who uses the designer, is obviously on the wrong track. The designer sucks.

That sounds like a real bug in ASP.NET. I assume you have other buttons, which would still fire the text changed ? It's a real bug if the text change event on the server, stops the client side onclick from working. Perhaps instead of using OnClientClick, you should use onclick directly ?

Hi Christian,
You are right. After entering emp id in text box, if i directly click on any button, textchanged event takes place. So could not get any solution yet how to stop textchanged event if we click on a button.

Note:As button is HTML control, so i am using onclick event only.

So perhaps you need to use an ASP.NET button for it to hook into the ASP.NET events engine properly ?

You're saying that ASP.NET is fundamentally broken. I'd google to see what other people have done, because surely other people have had the same issue.

This happens because in asp textbox if AautoPostBack is set to true, page is posted back when user leaves the control ( here textbox). So basically, when you click the button, first you leave the textbox control and then you click on the button. Hence TextBox' postback the data to server and as the page is reloaded you dont see any alert message. Subsequent click on button shows the alert message.

I just replicated your situation.

<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="true" ontextchanged="TextBox1_TextChanged"></asp:TextBox>
        <input type="button" id="btnOK" value="OK" onclick="return Button1_onclick();"/>


<script language="javascript" type="text/javascript">
    function Button1_onclick() 
    {
        alert('clicked button');
        return false;
    }
    </script>

Thanks,

Of course, that's what auto postback means. D'Oh! | :doh:

I've never used it, so I didn't really think it through, I just assumed that the event fired when he pushes a button to post back.
