View 6 RepliesI want to set the context key of a cascaded dropdown during pageload. means if tab index = 0 then contextkey = "1" otherwise 2;
[Code]....
I want to add a button in that page so that by clicking on this all the field will be reset.
is it possible?
My scenario is i have 4 tabs, under every tab there are five cascadded combo. So for page load itself it calling webservice at last and populate all parent cascaded dropdowns in all the four tabs.
now I have made changes but still now its not working. By defeault [ScriptMethod(UseHttpGet = false)], so i made it [ScriptMethod(UseHttpGet = true)]. now on tab change i added that function and it is calling the web methods when changing the tab. But after the loading its again call the webservice and this time as the get is true so its not getting any value. And in the dropdown its showing "error 12030".
i'm using the Ajax cascading dropdown list it works fine. But how to call the server side after the dropdown list populated....
i don't want to call those method in drop down list index changed because it may cause postback..
My 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.
View 1 RepliesI have dropdown1 that has some items in it.I also have dropdown2 that gets populated from a database based on whatever is selected from dropdown1.Dropdown2 has its first item as "Make Selection" and then appends the data from the db based on what was selected in dropdown1.
Now when I select an item from dropdown1 it puts the correct data in dropdown2 but as soon as I select another item from dropdown1 it appends those values into dropdown2. How can I remove the values from dropdown2 after a new item is selected from dropdown1?
i have a dropdown in a div which is toggeld visible true false the dropdown is populated with data on page load (is not postback) but is visible false when i click a button to make the div with dropdown visible true the div with dropdown appreas but the dropdown doesnot conatin data.

I can give the rest of the GenericDataAccess if that will help, but here's the problem; When I run a web page with this control, all the dropdown items are 'System.Data.DataRowView'I'm sure there's some obvious stuff I'm missing but I'm new to populating dropdowns.
I am using ASP.Net 3.5. I have fiiled dropdown list in javascript using ajax service but unable to get its selected value in button click event on server side.
View 1 RepliesMy dropdown list is populated by a group of names inalphabetical order.
However, I would like "Please Select Name" to be the first item in dropdown list.
I have 2 DropDownLists and use a cascadingdropdown to populate them which works fine. Problem I have is that I aso set the selectedvalue of the first DDL via Javascript. This doesn't then cascade the second DDL.
Code (for what its worth):
function SetControls(intAppId, intDelegateId){
var ddlApplication = document.getElementById('<%= ddlApplication.ClientID %>');
var ddlDelegate = document.getElementById('<%= ddlDelegate.ClientID %>');

I want to call the webservice method for repopulating the contains of cascading dropdown.
I dont want to write onparentchange method.
Requirement is simple. But dont know how to proceed.
On parent selection four dropdown will populate.
Now if I select the first child dropdown then again acccording to the choice of parent and first dropdown second, third and fourth will populate. And like wise.
Now how to call the webservice methods after selection of first one to repopulate the containt of the second, third and fourth dropdown.
I'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?
I wanted to use using database to populated the dropdownbut i am getting error as type or list space cannot be foundat ListCountry GetCountriesas its defined staticthe web methood code is in the same aspx.cs pagehow culd i use it if a different webmethod page .asmx is created

I'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.
I 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?
I am using asp.net 3.5. I filled dropdown list in javascript using ajax service but unable to get its selected value in button click event on server side.

I have a listbox that I am populating at runtime with javascript. After the listbox is populated I am using a button to get that value. on button click when I am trying to get the value it is the listbox item count is 0, Can anyone tell what's wrong after t he javascript populates the code,I have written the code in button click :
for (int i = 0; listbox1.Items.Count - 1; i++)
{
string s = listbox1.Items[i].ToString();
}
the value of count is showing as 0, though it has the values populated. What I am missing ?
How do I execute an JavaScript function right when an ASP.NET text box control is populated and focus is still set? The onChange event will not work because I need to programmatically move focus to the next form element after the JavaScript function has executed.
Is is very similar to this question. The marked answer is correct for the context on the question, but after some more testing it did not exactly solve my current issue.

I have a Collapsible Panel Extender inside a datalist.I have a hyperlink inside the panel within the datalist. I want to have a modal popup on clicking the hyperlink inside the panel and I want the modal pop up to be populated with the data from the navigate URL property of the hyperlink. Is it possible to do this? I am attaching my code,this is currently throwing an exception which I am guessing is because it is unable to find the hyperlink in the panel within the datalist :-

I'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").
