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 got one web page which is developed by using Asp.net. and in that page I have got one tab control which developed by using Ajax control toolkit (tab container). In that tab container i have got three tab pannels. In the first tab pannel have got two drop down list boxes and one image control box. wat I was trying to do is that by using calendar extender control in ajax control toolkit i was trying to display a day in the first drop down list box and month and year in second drop down list box. when user click on image control during run time a small calender will pops up and then user will select the propective date according to there choice and when they have finish selecting the date from the calender a day will display on first drop down list box and month and year will display on second drop down list box.
I was keep trying to do that but i was failed. then i took one test box from the toolbox and i was got success in displaying the user selected date in the text box by using ajax calender extender. How to display that date instead of one textbox into two separate drop down list boxes from which a user can select manual date from drop down list as well and from the calendar as well also when the page loads, the two drop down list boxes must show current date ( by default)
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 am using ajax cascading dropdown list one of my program. my code given below.
<asp:DropDownList ID="drpSeason" runat="server"></asp:DropDownList>
<cc1:CascadingDropDown ID="drpSeason_CascadingDropDown" runat="server" Enabled="True"
TargetControlID="drpSeason" ServicePath="Cascade.asmx" ServiceMethod="GetDropDownCategories" Category="category" PromptText="[Season]"> </cc1:CascadingDropDown>
<asp:DropDownList ID="drpb_SalesNo" runat="server" Width="70px"></asp:DropDownList>
<cc1:CascadingDropDown ID="drpb_SalesNo_CascadingDropDown" runat="server" Enabled="True"
TargetControlID="drpb_SalesNo" ParentControlID="drpSeason" ServicePath="Cascade.asmx"
ServiceMethod="salesNo" Category="Sales" PromptText="[Sale]"> </cc1:CascadingDropDown>
And my webservice code given below:
[Code] ....
My Cascading dropdown list work properly. But when I am trying to save my data by below code:
[Code] ....
My Add button doesn't post back. If I delete my cascading dropdown then my code work properly.
I use to populate Dropdown using javascript:
function populateDDL(ddl_id) {
var option_str = "";
var x;
for(x in datalist){
option_str += " <asp:ListItem Value='" + datalist[x] + "' Text='" + datalist[x] + "'></asp:ListItem>"
}
var country_div = document.getElementById(ddl_id);
country_div.innerHTML = option_str;
}
This is sure the datalist is not empty and also Dropdown list populated perfectly..but dnt know why after clicking on my page add button I am not getting the selected value.
I have a couple of dropdownlists and a button.when a user selects an item in the 1st dropdownlist,the 2nd dropdown is programmatically bound to a set of items(using an ajax request) depending on the value selected in the 1st dropdown.Then the user will have the ability to choose an item from the 2nd dropdown and click on the button,which performs some server side opeartions and returns the results.
But if the user tries to click on the button before the 2nd dropdown list is populated,user will receive an exception message.Instead of that I would like to prevent the user from clicking the button before the ajax request is completed to populate the 2nd dropdown.I tried using Button1.Enabled=false in the selectedvaluechanged event of 1st dropdown,which does n't seem to work.
I am new to WCF, I was using web service asmx before. I have trouble on making my wcf JSON ajax service work through http like asmx.Could you help me see what wrong in my code?My WCF services are defined in my website application folder. My aim is to call this service in my aspx page java-script code and return complex object back as JSON to my javascript. I have no problem on doing this through classic asmx web service.
When I try to test it through my browser by type this in the URL , URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc/GetAll. it return "Method not allowed."
But if I type just this URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc, it return this:
WCFCompanyService Service
You have created a service.To test this service, you will need to create a client and use it to call the service. You can do this using the svcutil.exe tool from the command line with the following syntax:
svcutil.exe URL-http://localhost:3849/WebServices/Account/WCFCompanyService.svc?wsdl
This will generate a configuration file and a code file that contains the client class. Add the two files to your client application and use the generated client class to call the Service. For example:
C#
class Test { static void Main() { HelloClient client = new HelloClient();
[Code]....
This is my Ajax-enabled WCF service code:
[Code]....
This is the web.config service model setting

View 7 RepliesI have a Cascading drop down list that is working fine to load the correct lists however I would like to have the last one initiate a query and display a datagrid on the same page containing the results of the query. Without Ajax involved this seems rather easy by using autopostback on the drop downs. If I could do it through Ajax that would be great but I can settle with having the page to reload to display the data. Right now I'm not sure how to do either. I enabled autopostback on the last drop down and wrote a method for it but I get an error at runtime saying:
Invalid postback or callback argument
[Code]....
Dont go away by looking a difficult probem.
I have a cascading dropdown which is dynamically created and does a postback based on a certain condition. How do i set the selected value after the postback
View 1 Replies<asp:DropDownList ID="ddlModuleName" runat="server" ClientIDMode="Static">

I am binding the dropdownlist by using ajax cascading drop down now i need to preselect the dropdown value in code behind page in page load (for update operation) is it possible
Bit of a strange request but is it possible to set the selected value of a cascading dropdown in code? I have 2 dropdowns, the second is populated using the value of the first. Heres my markup:
<asp:DropDownList ID="ddlApplication" runat="server" CssClass="form"></asp:DropDownList>
<ajaxToolkit:CascadingDropDown
ID="cddApplication"
runat="server"
TargetControlID="ddlApplication"
Category="Application"
PromptText="[select an application]"
ServicePath="webservices/Application.asmx"
ServiceMethod="GetUserApplications" />
<asp:DropDownList ID="ddlDelegate" runat="server" CssClass="form" />
<ajaxToolkit:CascadingDropDown
ID="cddApplicationUser"
runat="server"
TargetControlID="ddlDelegate"
ParentControlID="ddlApplication"
Category="ApplicationRole"
PromptText="[select a user]"
ServicePath="webservices/ApplicationRole.asmx"
ServiceMethod="GetApplicationUsers" />
Basically I want to set the selected value of ddlApplication, then populate the ddlDelegate, then I want to set the selected value of ddlDelegate.
I have a RadioButtonList and two cascading dropdown linked to corrspoding dropdown control. Based on radiobutton's selection, the cascading will be prepopulated with some values and one value is selected in both dropdown.
I want to disable the cascading dropdown/dropdown after values are filled and selected on selection of radiobutton selected in RadioButtonList.
I tried to disable it, but in that case dropdown is getting empty.
I have a web form where I have three dropdowns for Country State And City and there corresponding
ajaxToolkit:CascadingDropDowns.
The dropdowns are working perfectly fine with the web service methods. i.e country loading initially and then State as per selected Country and City as per the selected City.
The problem occurs when I try to set selected values in these dropdowns as per the Values previously saved.
The Country loads properly and the selected value is set according.
The State is filled as per the selected country but its selected value is not set.
The City is not loaded at all (as the state doesn't have a selected value)
The Code is as Follows:

n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript">
function NextClicked() {
var _ddlStatus = document.getElementById("<%=ddl.ClientID%>");
var _selectedIndex = _ddlStatus.selectedIndex;
var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) {
_btn.ValidationGroup = "G1";
}
if (_selectedIndex == 2) {
_btn.ValidationGroup = "G2";
}
}

View 4 RepliesI have developed a wcf service for asp.net ajax client. It includes the following steps.
(1) Created WCF sevice contract with the operation "DoWork()" which will take string as input and retun string as output.
(2)Implemented the above operation contract(attributed the implementation class with aspnetcompatibility requirement as enabled).
(3)Added the webscriptenabled to endpoint in web.config file.
(4)Hosted the wcf servie.
(5)Downloaded the javascript file from the service.(e.g.,http://localhost/service1.svc/js)

Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.
In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.
How to prevent this one. It should be on PRIMARY Only.

<tr> <td ><asp:Label ID="lblContactType" Font-Bold="true" Text="Contract Type: *" ForeColor= "red" runat="server" AssociatedControlID="ddlContactType"></asp:Label> </td> <td > <asp:DropDownList runat="server" ID="ddlContactType" DataSourceID="SqlDataSource2" AppendDataBoundItems="true"
