Am using masterpages.I have written following code to add rows to dynamictable with html controls.
I need to load data from database in cascading dropdownlists(like country,state);this javascript code is not accepting asp controls.can we load data in cascading html dropdowns? using javascript/AJAX?
html:
<input type="button" value="Add Row" onclick="addRow('dataTable')" /> [code]....
I'm trying to use two cascading dropdownlists with the same values -- one shows a code, and the other a description. They are sorted alphabetically, so they have the same values, but not the same index. Both are generating correctly. What I am trying to do is set the abbreviation when the description changes (and vice versa).If I use this javascript, it changes on the web page, but I get a null value returned to the form handler. If I comment out the CascadingDropDown control and load the TrickAbbrev from a database it all works.
function scrTrickNameOnChange(ddlId)
I have a web app with several groups of cascading dropdownlists. All the cascading dropdownlists work as designed, but now the app is in the live enviroment with multiple users they are getting error 500 messages returned in some of the dropdownlists. Just wondered if there is a set amount of time to populate between selections? As these users are sometimes waiting tens of mins betwen selecting the values.On some of the dropdowns i'm pasing a date to the method using session variable whether this could be the issue? an example of one of the methods is below:
[Code]....
Here is the case:
I use Visual Studio 2008 ASP.NET 3.5
I have a DetailsView control with several fields that is in insert mode. Three of them are the source of my problems and headaches.
I have three DropDownLists in template fields.
The first one is OK, bound to it's designated field in table1 in the database. The next two however have to change their bound tables according to the SelectedValue.
So far, I've managed to get it working, BUT when I insert the data I've entered, these two DropDownLists are not entered into the database.
DropDownList3 - the list that controls the other two DDLs
DropDownList4 and DropDownList5 - the list that need to change their items accordingly
DropDownList3 has six different values, so I have 6 tables for each of the other two DDLs
However I have only tried with one to see if it would work, that's why the Sub seems incomplete.
Here is the relevant part of the code:
[Code]....
And the DropDownList3_SelectedIndexChanged sub:
[Code]....
If I leave SelectedValue='<%# Bind("shelves") %>' and SelectedValue='<%# Bind("type") %>' in the <asp:DropDownList> tag of the two DDLs that change values, I get an error when the first one does the postback.
The error is:
Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control. This error, I spent a whole day looking through forums and knowledge bases, but I could find nothing that solves my problem. Maybe the problem is me, but my boss wants this done, despite it is not my area of expertise to write code.
I have 2 dropdown list in my page these are my code
<asp:DropDownList ID="DDLzone1" runat="server" CssClass="DDlzone" OnSelectedIndexChanged="DDLzone1_SelectedIndexChanged" AutoPostBack="true">
</asp:DropDownList>
protected void DDLzone1_SelectedIndexChanged(object sender, EventArgs e) {
DDLstore1.Items.Clear();
DDLstore1.Items.Add(new ListItem("select shopping center", ""));
[Code] ....
When users click on DDLzone1 Â value of DDlStorre1 will changeÂ
Here for both ddl i set autopostback ="true" Â for this it change ddlstore when page is post backÂ
I want when users click on DDLzone1 value of DDLStore1 be change without loading page again ...
I have some cascading dropdownlists using the ajax toolkit I have a set up datatables in an xsd file. Then use these in a webservice to populate all the fields ... this all works great but now i need to pass an additional paramter to the first dropdownlist ( a date) but don't know how to do this? The method is below...
[Code]....
The other code is:
[Code]....
The first change would be to the tableadapter to add a param to the code i.e
AuditWebDS.TeamsDataTable teams = teamsAdapter.GetTeams(calldate);
but how do i get the calldate param to the webservice method... i tried a session variable but it comes up with session is null ? Is there another better way?
I want to populate the cascading Dropdown values without Promttext.
Scenario is .If a single value is retrived from the database then I think no need to populate the promt text. It may populate only that value and call the next function from the inside of it. Can it be possible using web methods.
I am trying to get two cascading dropdownlist to work but cannot get either to populate. How do I de-bug this? I'm not getting any errors, just blank dropdowns.
I've been trying to fill in webservice from SQL Server. But in-case this was the problem. I found an example on this site to fill with test values, but this still does not work. Since I cannot even get first to populate, to simplify I'm just giving code for first dropdown and its function(s)
[code]....
after
[Code]....
This line i get an error. Means nothing is populating there and no method is calling in .cs page too.in the script it returns error. my .cs page code for populting first dropdown as follows,
[Code]....
and the webmethod as follows
[Code]....
[Code]....
I'm comfortable populating dropdownlists in a standard webform, but I seem to be having trouble populating them from within a gridview or listview.I know that I'll probably need to use the find control method, I've had a stab at it with the following:
[Code]....
The purpose of this is to allow someone to look at a bunch of records, and in a dropdownlist add an item to a group, but this "group" is in a separate table, so I want to take whatever value that select in the dropdown menu, lookup their user id, and add both bits of information to the other table, so it's technically not even editing, even though i suspect I'll need to use the edititem template?
I've got 3 SqlDataSource controls, and 2 dropdownlists and 1 detailsview on a page. The first SqlDataSource is associated with the first dropdownlist, and second SqlDataSource (which is filtered based upon the selection chosen in the first dropdownlist) is associated with the second dropdownlist and the third SqlDataSource (which is filtered both by the selection of the first dropdownlist and the second dropdownlist) is associated with the detailsview. The idea is the user selects something in the first dropdownlist, and it is supposed to update what is returned by the second SqlDataSource control and second dropdownlist, and that in turn is supposed to change what is returned in the third SqlDataSource control and it's associated detailsview. All of the dropdownlists have AutoPostback set to True.

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'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 want to add items to a dropdownlist with values return by a webservice which will be called from javascript without cascading extender...

I have the following code which toggles the visibility of one of a pair of DropDownLists based on the selected radio button. This code works but my problem is that I have several sets of controls just like this on a single form. How can I use a single JavaScript Toggle() function, irrespective of the ID of the RadioButtonList that triggered it?
function Toggle()

var list = document.getElementById("produceDDL");
var inputs = list.getElementsByTagName("input");
var selected;
for (var i = 0; i < inputs.length; i++)
{
if (inputs[i].checked)

selected = inputs[i];
break;

I've been working on my first version of an ASP.NET app, using cascading dropdowns. I've got 2 dropdowns on a page.
However, the third major control on the page is a details view. It works fantastic, with the cascading dropdowns, to display information from the second dropdown, and allow the user to edit that data. All well and good. But now, in testing, I suddenly realized that I've got no way of displaying the details view if I want to let the user enter new data, which would show some information in the second drop down.
