Web Forms :: Store Selected Index Of Listbox In Hidden Field And Then Return To That Value On Postback?

Jan 4, 2011

I must be doing something wrong, but this makes sense to me. I have a Listbox loaded with tons of items from a datasource. A user clicks one of these items it grabs the selectedindex (an integer) and stores it in a HiddenField (works fine).

Now when the page does a complete a refresh (after postback) I want the ListBox to go back to that selectedindex that is in the HiddenField. Problem is, it seems that after postback the HiddenField is empty? Then I thought about storing the value in an Integer variable in code, but that is simply coming up as a zero at all times.

Question 1: What is the best/simplest way to do this?

Question 2: How?

I am currently grabbing it on selectedindex change

Feb 28, 2011

How to get the selected item from the listbox in the selected index changed event. I tried: Label1.Text = ListBox1.SelectedItem.Text; It is giving me object set to null reference.

foreach (ListItem item in ListBox1.Items)
if (item.Selected)
//lblResults.Text += item.Text + "
Label1.Text = item.Text;

No use, no value coming in to label.

Web Forms :: ListBox Selected Index Changed In A TabControl?

Oct 25, 2010

As you can see in the picture below i've got a Page control with inital letters which cotains a listbox showing different wood articles. When i click on a Tab, the selected tab page get's a new Listbox control with the wood articels starting with the selected initial letter.

Creating the listbox:



When i click on a item inside the listbox, following code will be executed:


So far, it works fine for me. But when i change the selected Tabpage, the first SelectedIndexChanged in the listbox in the new shown tabpage is not recordnized. That means i have to select a new item and click on Search = the selected Item is still the item i selected before i changed the tab. Then i select the item again and click on search the index changed is recordnized. So why do i have to click two times on search to get the new selected item after a tab page changed?

Here is the full code:

Web Forms :: Dynamically Populated Listbox Always Return Selected Items As False?

Mar 10, 2011

I have the following code which simply gets data from a table and populates the questions_lb listbox with items. I have a button on the page, which when clicked, should write (on submit) the selected state of each of the items. The code below writes the text values of each of the items fine however it always writes the li.Selected as False even though i have selected items from the list. Note that you can select Multiple items from the list. Does anyone have a clue why its not writing 'True' for an item that is selected on submit?

Hidden Field Value Lost On PostBack?

Mar 12, 2010

I have a hiddenfield, which I want to save the scroll position of asp.panel scrollbar during postback, and when during postback this value is called back to set the scroll position.

Using javascript I can grab the value from the scrollbar, and assign it to the hidden field, but when I post the page back the value has gone.

Here is my code snippet:
<script type="text/javascript" language="javascript">
function SetScroll(val) {
[code].....Am I missing something? How do I keep the value during post back?

Javascript - Set Hidden Field Value After Postback.

Jul 29, 2010

I have a component that determines a value on a postback event.

protected void Button_Click(object s, EventArgs e)
HiddenField.Value = 5;

There's more involved in the value of course, but HiddenField is an asp:HiddenField control with runat=server set. I have in my javascript:

var id = $("#<%= HiddenField.ClientID %>").val();

The code in the javascript is set to be run only after the postback has occured (a different client click event) for the purpose of passing the hidden field value via QueryString to another URL (since i can't do a response redirect on postbacks and the client wants it in a different page anyway).

I tried adding:

ScriptManager.RegisterHiddenField(HiddenField, "Value", string.Empty);

To a !Page.IsPostback section of code, but the ID is still not set when the javascript is run.

Hidden Field Losing Its Value On Postback?

Jun 7, 2010

I have a ascx page where I am using a hidden field to store the value of a the drop down box as it is generated using a google address finder. My problem is that when I try to store the value directly in the hidden field :

hfDdlVerifyID.Value = ddlVerifySS.SelectedValue;

in the event of a button click, the value is stored but on postback is lost again. Whereas, if i try to use Scriptmanager to do it, nothing is stored.

getBuild.AppendLine("$get('" + hfDdlVerifyID.ClientID + "').value = $get('" + ddlVerifySS.ClientID + ").value;");
ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "storeHidden", getBuild.ToString(), true);
// Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "storeHidden", getBuild.ToString(), true);
string test = hfDdlVerifyID.Value.ToString();

Javascript - Hidden Field Data Lost On Postback

Nov 18, 2010

I am working on an ASP.NET application (well supposed to be deploying it about 3 days ago) and my hidden fields are loosing value when the form gets posted back..

I am using them to store information i write using javascript and on my own machine this works fine but as soon as i deploy it on our server everything else works except these values are lost..

I am using the .NET AJAX control toolkit on the same page and have noticed my calander datepicker also looses the data..

I have checked using firebug and the data is definitely getting post to the server but is getting lost somewhere!

State Management :: Hidden Field Value In User Control / Make The Hidden Field Save Its Value?

Mar 23, 2011

I have a custom user control which contains a asp hiddenfield object. The value of this hidden field is being set using javascript and I have verified that the value is being set properly. When a postback occurs the new value is not being saved and I cannot access it in my code.

I believe the problem is because the user control is not saved in viewstate and therefore the hidden field value is not saved accross postback. How can I make the hidden field save its value? I tried accessing it from the early page cycles and still no luck.
