Data Bind and View State

I have the simplest web page (using code-behind):
<body>
<%# MyText %>
two buttons - button1 and button2
</body>

My code-behind web page is very simple too:
public class WebForm3 : System.Web.UI.P age
{
protected System.Web.UI.W ebControls.Butt on Button2;
protected System.Web.UI.W ebControls.Butt on Button1;
protected string MyText;

private void Page_Load(objec t sender, System.EventArg s e)
{
//DataBind(); // Don't want to bind here!
}

// Web Designer code omitted
private void Button1_Click(o bject sender, System.EventArg s e)
{
MyText = "In button1 handler";
DataBind();
}
}

I don't have a handler for button 2 (it only submits the page), and I DON'T DataBind in the PageLoad function. I only DataBind in the button1 handler.

Here's my problem/question: when I click on button1, I see the text "In button1 handler" on the page, as expected. However, if I click button2, the text doesn't disappear, which was really surprising to me. How does the bound text persist there? I know it has something to do with view state, because the latter changes when button1 is initially pressed. That is also the only way the server can know what the string is. I just haven't seen any documentation linking between binding literal text and view state. How do I disable this (i.e. make sure the bound text isn't saved in view state)?

Thanks,
Eran

Hi,
If you use <%= MyText %> you will find that it works as you expected

Is there a way to carry data that I have already read from the datagrid from page to page? I am looking at my Datagrid that I page through and when the user says get the next page, I have to go to the database to get the next page. Is there a way to use the dataset to allow us to read back and forth in it instead of going back to the database to get it? Thanks,

I have an ASP.NET 2.0 page with two DropDownLists. I am using declarative data binding wherever possible and trying to minimize the use of code. The list of values in DropDownList DDL2 should be (filtered) dependent upon the selection in DDL1. I think this inevitably needs some code, but I'd be happy to be told otherwise! I have some code to handle OnSelectedIndexChanged for DDL1 that sets the FilterExpression associated with the...

Hi, I have a synchronous socket server which my app uses to read data from clients. To test this I have a simulated client that sends 100 byte packets. I have set up the socket server so that its buffer is bigger than this. I did this expecting the data to be read in one pass.

My app has an asynchronous socket server. It will have 20 clients connected to the server. Each client sends data every 500 millisecondsThe Connections once established will not be closed unless there is a problem with the connection. I need to know which client has sent the incoming data as each client has its own buffer on my "server" app. I am using the standard asynch socket code from MSDN to listen for connections and they...

Hi - This could be a simple question. When I relate two tables in a datasetet, how do I get that relation to show up in a GridView? The only way I've done it, is to create a separate table in the dataset with a join query for the GetData() select method. I use ObjectDataStore to couple the GridView with the table adapter on the dataset. If I point the ODS at the child table, the GridView will bind to the "normal" select and I end up...

I have created a custom DataSourceControl to interface to a search engine. The DataSourceControl exposes multiple views of the same data. The first is the actual search results. The other views are for information about parametric data (i.e. this state has 4 hits, that state has 6 hits, etc.) So far, I have almost everything working perfectly. I had to move the code to actually execute the search up in the the DataSourceControl. This...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
