State Management :: EnableViewState Is True But Still Doesn't Keep The Value After Postback
May 8, 2010
My dropdown controls do not keep the values after postback even though their EnableViewState is = true and in Page_Load I fill my controls ONLY if not postback.
My controls are inside a panel and the panel's EnableViewState is set to true as well...
To see the page you can log in as test and password is 12345
click on search page and set a value to say Gender and Ethnicity and click submit.
You will see the results, then navigate to number 2 or 3... You will see that it refreshes the controls and sets them to default.

I have the following tabs. After a postback, the tabs automatically gets focus back to 0. I want it to keep on the same tab before the postback. What's a great way of getting this done.
<div id="settingspagetab">
<ul>
<li><a href="javascript:void(0)" onclick="changeTab(0)">General</a></li>
<li><a href="javascript:void(0)" onclick="changeTab(1)">Site Layout</a></li>
<li><a href="javascript:void(0)" onclick="changeTab(2)">Marketing</a></li>

I am creating a simple string of values that get added to a label after a post back. I am setting the values thorugh ViewState. However, my appended values do not get updated until AFTER the 2nd postback. Example:
On Page_Load the label displays a "0";
If I enter a "1" in the text box and click the button the label still displays a "0";
If I click the button again (the 2nd postback) then my label correctly displays "0,1"; This works for whatever value I enter after. i.e. "0,1,35,hello world", etc.
What I am I missing? Code Below.
.ascx - I left out inherits and codebehind

I got the viewCustomer.aspx page sending parameter to EditBusiness.aspx page as per below coding .
After that i retrieved to EditBusiness.aspx.cs by using (Request.QueryString["customerId"] ) and save in session . Then i tried to use the session in the EditPersonal.aspx and EditOther.aspx is worked but then back to EditBusiness.aspx the customerId parameter is disappeared . I believe is because in EditBusiness.aspx.cs using string customerId = Request.QueryString["customerId"] . Even I have tried cookies but its doesnt work .
ViewCustomer.aspx.cs
protected void grdCustomer_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Mod")
{
Response.Redirect("EditBusiness.aspx?customerId=" + e.CommandArgument.ToString().Trim() + "&mod=Modify");
}
EditBusiness.aspx.cs
string customerId = Request.QueryString["customerId"]
Session["customerId"] = customerId.ToString();
EditPersonal.aspx.cs and EditOther.aspx.cs
string customerId = Session["customerId"].ToString();
qry = "select *from customer where customerId = " + customerId;

I have a slight delemma that I have not been able to work out.
My Scenario is:
Page_Loads > Calls Sub Random Data Retrieved from a Table - Displayed on screen & Sets Variables from Row(0) for an Insert Statement > Click Button to Insert those Variables.(essentially, the Insert Statement Parameters are Dynamic in that they change each time the page loads)
The Problem I am having, is that each time the page loads, I need a New DataSet, and the Page_Load is operating too quickly, changing my variables on postBack and ultimately, inserting the new values that are now loaded.
How can I:
Page_Loads > Get and Set the Variables I need > Protect Those Variables from changing on the Next Postback (so the insert statement gets the values Iwant to insert but also set and get the next ones)?
If Not Page.IsPostBack Doesnt Work for me in my Page_Load because each time the page.loads, I need those new Random Variables from a DataSet
Someone had Mentioned ViewState, but I am uncertain how to use it. I just want to protect the variables so that it inserts properly

I am in beginner level on developing web pages. I was coding on desktop applications and as you know it is easy to say that web applications are extremely different than desktop applications.
I wonder why data are lost between postbacks.???? And what is the best way not to lose the data belonging to a specific control (especially gridview). Session or viewstate or anything else?

Never had this happen before. I just upgraded my site from 3.5 to 4.0. Here's the scenario:
1.) I have a literal on a web form, in an UpdatePanel.
2.) On PostBack, the Literal's "Text" property loses it's value. The ViewState is enabled throughout the page. Further, I changed the Literal to a label and it also has this problem. The TextBox's appear to keep their values.
3.) If I remove all of the Ajax controls (which currently is just the UpdatePanel and the ScriptManager) then the Literal control keeps it's value through PostBacks.
4.) There is no client side JavaScript where I'm manually changing the values of these controls. They are only editted in the server side events.
I have read that setting the AutomaticDataBind property in the web.config could remedy this but I can't find any documentation on it and I don't know where to put it in the web.config to even try it.

There is button(btnOpen) and a textbox (txtResult) in the page.
Once I clicked on btnOpen, a modal dialog will appear, displaying TextBox1 and Button1.
The user is required to type something in TextBox1 and I want to pass the TextBox1.Text into my database but when I try to do that, the value actually = "", which is gone.
So I created this test program to illustrate by passing the value into a txtResult.
Can anyone guide me on getting the TextBox1.Text value?
Besides that, is there anyone to tell more about what does this lines of code do?

I have a form that takes the user information. When the user submits the form, after the postback, I need to get all some of the textboxes in the form cleared. I tried disabling the ViewState and ViewStateMode. But both of them failed. Also tried disabling the cacheability for the page. I know I can clear the textboxes on the page load event. But I am curious to know if there is another way to do this.

My app has broken after upgrading to ASP.NET 2.0. The problem is that Request.QueryString is empty when the SelectedIndexChanged event of a IE Web Controls tab strip is fired. It worked perfectly in ASP.NET 1. I have the tab strip contained within my own UserControl.

I ve been searching for this on various forums and came through a number of supposed solutions which didnt work for me.
My web form works perfectly for me when on development and after publishing on IIS but when I try to access remotely the session value is always null.
I do these things in the following order and when accessing remotely I always get the exception i throw when session is null.
I debugged it and my list is never null when reaching the assignment point.
[code]....
in webconfig I have the following tag which I saw as an answer in many forums
<sessionState mode="InProc" cookieless="true" timeout="200" />

I have "n" <tables></tables> on my page and each <table> has One(1) <asp:CheckBox.. Enable ='true"/> and "x" <asp:TextBox Enabled="false"..>. Each Table looks as follows
[Code]....
When I click checkbox, it calls javascript function and enables textboxes (I have added onclick attribute to checkbox). Page also has <asp:Button ...Text="Submit"/> whcih actually grabs the data from the textboxes on the page and send it to the databse. Here is the Onclick event of the <asp"button../>
[Code]....
If the exception is thrown , textBoxes are not reset but on postback textboxes appear as disabled (values are not reset)
So here is what happening on postback when exception is thrown
1) Values are not reset (that is what want)
2) Texboxes appear as Disabled (that is what I don't want on exception, REMEMBER I enable textBoxes using client side script)
How can I keep the textboxes enabled = "true"

I have a linkbutton that displays a different record each time the page is loaded. When I first bring the page up, I can hit F5 repeatedly and the linkbutton works properly rendering a diff record each time. But in a dropdown list, or any other control that causes a postback, the linkbutton remains static, why?
In my Page_load I have
AccessDataSource1.SelectCommand = "SELECT blah FROM table where trim(recid)=" &
"'" & rndVal &
"'"
AccessDataSource1.DataBind()
LinkButton1.Text = DetailsView1.Rows(0).Cells(1).Text

Im currently experincing some difficulties with the viewState. The scenario is that i have a datagrid that has a column of buttons that when pressed will store a value in the viewState. I have already done this on one occasion in the same page, but for some reason the second item in the view state is always returning null, even when i hardcode in a number in before the postback. Im at a loss as to why this is happening, anyone expericened this and know what is wrong.
EDIT: Ive found out the cause, Its due to when you click a button in a data grid it does the postback code first, then fires the event handler, so of course the view state would be empty as it is coded to be set in the event handler for the button click. Is there any way to avoid that? So the event code is fired before the postback code?

I have a simple aspx Page, which html contains:
[Code]....
and code behind:
[Code]....
This is quite simple. When I press btn1, it sets correctly the Session Key. And this is then the issue arrives: When I press one of these buttons, this is the sequence of what happens:
Global.asax: Session_Start
MyPage.aspx: Page_Load » btnX_Click
So, everytime there is a PostBack, even before the Page loads, the session starts and generates a new Id. This way, I loose everything during the PostBack. My Session State configuration:

This is running on VS 2010 + V3.5, on IIS5.1. The Page header configuration is default.
