State Management :: Retaining The Dropdown List Values Moving From One Page To Another

Mar 27, 2010

I have four dropdowns in the first page and then a button which saves the selected values from the dropdown to a session state .

In the second page I do have previous button which comes to the first page. My problem is that the dropdown values are not getting preserved.

Here is my code for the First page

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using MyBusinessLayer;
using MyDataLAyer;

[Code]......

The problem is that I get the error object instance not set to an instance of an object

State Management :: Persisting DropDown List Attributes Across Page Postbacks?

Oct 12, 2010

how can DropDownList attributes be persisted accross page Postbacks?

Example:

DropdownList1.AutoPostBack = True
DropdownList1.items(0).Attributes.Add("Attribute1","somevalue")

On Postback the attribute is no longer available (ie. attributes.count=0).

I tried persisting using the code below, but was unsuccessful:

Before PostBack: ViewState.Add("DDL","DropdownList1")
On PostBack: DropdownList1 = ViewState("DDL")

This generated the error: DropDownlist is not marked as serializable.

I than tried:

Before PostBack: Session.Add("DDL","DropdownList1")
On PostBack: DropdownList1 = Session("DDL")

This did not err but attributes were still not available.

State Management :: Application Crashes - Lost All Values Of Dropdown

Jul 23, 2010

I have a web form with a whole bunch of drop down lists (mainly) that works perfectly well and has been for some time. However, we've found a scenario that seems to corrupt the viewstate of this form in someway, or cause it to lose it's viewstate. The problem occurs when the user has this form displayed, then clicks on a link that opens up another window. A few more steps to open up a second and third window, followed by a write to the database. Then the user closes these windows down, leaving this original window open. At this point, the user selects something from one of the dropdowns. And the app crashes because the dropdowns have lost all of their values (and so a bit of code that is trying to work with one of the ddl's selectedvalues fails).

When the user selects this dropdown, the page_init event fires, followed by the page_load with postback = true. The dropdowns themselves are defined in the aspx page markup, but the values of them are generated and added in page_load (where postback = false). I've relocated the code to populate these controls to the page_init code and now the app doesn't fall over, because the values are re-populated. However, all of the selectedindexes are being reset, so the original values are lost and the screen redraws after this postback with all of the dropdowns reset.

C# - View State Not Retaining Values?

Jan 7, 2011

I'm trying to retain "visible" property of a control using view state in the following way

public bool showstatusbox {
get { return Convert.ToBoolean(ViewState["statusbox"]); }
set { ViewState["statusbox"] = value; }
}

Is there anything I should do other than this to retain value. Because, though I store the value in view state, on postback, its becoming null.

State Management :: Moving Data Along The WebPages?

Sep 30, 2010

ViewState are used between same page Request and Response.

Session variable will stay throuwut the browsing until the Specified Expiration event.

Hidden Input control will be used whithin same page as well.

Are there any good exmples of this differences?

I wants to know the practice use here, because in hte current team, people are not prefering to use viewstate object due to some Heavy load of that object.

So i am try to use Session variable and working fine but can not see in the Viewsource of webpage.

Hidden Input control still make little weight on page compare to session..

I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).

State Management :: Setting Session Values In Generic Handler And Accessing Them From A Page?

Jun 10, 2010

I have a generic handler in which I fill up a Session variable. I implemented the IRequiresSessionState interface, so it shouldn't be a problem.

In a given page, I want to display that value, but it seems like the value is always empty. Is it because the session that is accessed and written to in the handler isn't the same one that is used on this page?

In the handler, I used context.Session["EID"] = "somevalue";

edit: i found out what the issue is but I do not know how to solve it. It's because I have this Java applet which reads out an eID, calls the handler to store the data, but the session used by the applet is not the same as the session used by the browser... so how could I exchange this data in a safe way?

State Management :: Session State Returning Null Values?

Apr 29, 2010

I have a clear button and a textbox in an aspx page. I set the session variable in this page as

String str = Textbox1.Text;

Session["TypeIds"] = str;

and I clear the sessions in a clear button event as

Session["TypeIds"]=null;.

Then when the user types some value in the textbox ,on Response.Redirect on another aspx page, the session variable returns null values.It does not retain its session state. The session state has to be maintained in the next page. Is it because this clear button event and setting explicitly to null creates this problem?

State Management :: Populate Dropdown From Cache

Oct 6, 2010

I wanted to know the best practice for caching data. Say I have some control example a dropdown list which is populated from my db. Now this dropdown is global and used across many pages. I was thinking of not going to database everytime to fetch data for this dropdown and put the result in Cache. And then populate this dropdown from cache. Is this a good practice or if there is another approach. Can I store my datareader in cache and then use it globally. Also could I do this in application start event?
