Gridview SQL Parameter Null From Javascript / Ajax Populated Dropdownlist
Sep 7, 2010My issue is similar to [URL] how-to-use-the-value-of-a-selected-value-from-a-dropdownlist-populated-with-ajax but I am using ASP.NET, not PHP. I have a dropdownlist that is populated by another dropdownlist's current value through ajax. So if DDL A is 'NY', DDL B is populated with different data relating to 'NY'. I need that data to be posted back to the server because this affects an SQLDataSource parameter. However, as far as I can tell, the value is always null after postback resulting in the gridview to be empty.

AJAX :: Repopulate Cascading Dropdown List Using Javascript
Mar 31, 2010I've 2 dropdownlists, both are binded to a cascadingdropdown. Whenever I select an option in the 1st dropdownlist (parent), the options in the 2nd dropdownlist (child) will repopulate based on the options I selected in the parent dropdownlist. I need a javascript function to reset the options of both dropdownlists in their initial state (the prompt text).
I've tried changing the selectedIndex of the parent dropdownlist. However, this only changes the selected option in the parent dropdownlist. It does not reset the child dropdownlist to its initial state (which is supposed to be disabled and without any options). Need the script to reset the chained dropdownlists?

AJAX :: Unable To Cascading Dropdown When Changing Value With A Javascript Event
Mar 15, 2011I'm back with my CascadingDropdown problems.
This one must be the last but not the less annoying.
I have a set of dropdowns ruled by 3 CascadingDropDowns extenders.
I would like to change the value of these dropdowns by javascript.
This works for the parent dropdown but not for the others.
Here is the javascript code used :
$find(element_name).set_SelectedValue(valeur,valeur);
$find(element_name)._onParentChange(null,true); // still wonder what are the parameters for...
This code does not give me any error but nothing change on display.
The strangest thing is that when I check the value of my dropdown with firebug, I get this :
<input id="Pane2_content_CONNEX_ClientState" type="hidden" name="Pane2_content$CONNEX_ClientState" value="D:::D:::">
And the value that I set is "D". But on the webpage, the dropdown displays a "A" which is the last selected value.
C# - Pull Data From A Javascript Populated Table?
Jul 13, 2010I am trying to pull data from my populated javascript table. How do I pull the value from a javascript row? I am using
for (var i = 0; i < rowCount; i++) {
var row = table.rows[i];
//This is where I am having trouble
var chkboxIndicator = row.cells[0].childNodes[1];
alert(chkboxIndicator);
//
if (chkboxIndicator == indicator && Checkbox.checked == false) {
table.deleteRow(i);
rowCount--;
i--;
}
}
which has an alert message of "undefined". I tried .value and .text as well and no progress. How do I get the text from the childNodes?

Using Ajax To Populate Web Page, But The Populated HTML Isn't Working
Sep 28, 2010I'm using Ajax to dynamically populate a DIV. I have each page content stored in XML files as CDATA. When a user clicks on a link from the navigation bar, the Ajax loads the XML for that particular page, parses it, and populates the DIV with it's content.
Everything is working GREAT, except for one thing. I have a jQuery modal popup whose markup is loaded from that page's XML file. The .js and .css files from the jQuery plugin are all loaded, and when this is HARD CODED (i.e., not loaded from XML), it works fine. But when it's loaded from the XML, the modal doesn't work.
When the page is loaded from the XML file- What the page is supposed to do is load the HTML from the XML file, which it does, and there's a hyperlink that when clicked, it's supposed to create the modal popup window. Instead, clicking on the link does NOT fire up the modal popup window.
When the page is hard coded- it does everything it's supposed to do.
A live example is at:
http://mikemarks.net/clientSites/tabras/
Click on "The Band", and at the bottom you'll see the hyperlink called "Demo". Clicking on that should bring up a modal popup window, but instead as you can see it just takes you to the top of the page.
Below is my markup (notice the div id="copy", which is the placeholder for my HTML content that's loaded from the XML file), my Ajax JavaScript code, and my XML file (which is shown as the markup that's loaded into the div id="copy").
<div id="leftTwoThirdsColumn">
