I am new to MVC, I have a form in which selection of one dropdown should reload another dropdown. On selection of the dropdown, I use a jquery post to get the data and my viewstate is reloaded with new data, but I am not sure how to set the newly loaded viewdata to load the dropdown again.
How can i generate dropdown lists based on what has been selected in the checckbox list. Below is an example of what i need. if the user selects the options day, lotID and waferID, then 3 cascading dropdown lists should be displayed. And then a gridview displays data based on what has been chosen in the dropdown lists.
Day LotID SlotID WaferID VendorID ToolID LocationDetected ProcessStep Stage Precipe WaferStartMaterial WaferStartVendor WaferStartLot WaferDiameterCOA WaferMapTitle BreakPoint BreakpointSide BreakpointMeasurement

I am developing a web site that has holiday prices which are taken from a different database and loaded into two SQL databases.I have two girdviews to display each of the prices data.What my issues is that I need to load an SqlDataSource on database 1,when 'Family' is selected from a dropdown list and run an SqlDataSource on database 2 when 'Themed' is selected and then run both when 'Don't Mind' is selected.
Question basically crams it all in... I'm loading a page with a querystring (ID), and I need to use that ID to set the selected item of a ListView when the page loads. The ID is a DataKey on the ListView. I have no code of value to post--none of my attempts at this work.
I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
In my web form, i have 2 drop downlist controls. eg. dropdown1 and dropdown2. I will change the dropdownlist1 item, consequently selectedindexchanged event fires and reloads the dropdownlist2 items. And i have another button also in order to get the result based on the dropdown1 and dropdown2. Lets say for example, i have a list of countries in dropdown1 and a list of states in dropdown2. I selected "India" in dropdown1 and correspondingly "Tamilnadu" in dropdown2. And then click a button which calls the dataset based on dropdown1 and dropdown2. The problem i face here is, whenever i click on the button to load the dataset, dropdown1 value remains the same as the dataset is not called again, whereas the dropdown2 value changes to the first one as it gets called automatically during postback. For your information, I have loaded both the lists in the page load using (!IsPostback) property.

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:
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 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)

i tried with pagemethods getting the dictionary object using JS function and thought of binding it.
but i am unable to bind the list.
//html code Religion <asp:DropDownList ID="ddlReligion_RS" runat="server" TabIndex="6" onchange="GetCastes_RS(this.value);"> </asp:DropDownList> <br /> Caste <asp:ListBox SelectionMode="Multiple" ID="lstBxCst_RS" runat="server"> </asp:ListBox> //js function function GetCastes_RS(relgnID) { abc.BLL.Services.AjaxService.GetCastes(relgnID, function (resp) { var ddlCaste= document.getElementById("<%=lstBxCaste_RS.ClientID%>"); ddlCaste.length=0; var castesList = resp; alert (resp); if(castesList.keys.length >0) { for(var i=0 ;i< castesList.keys.length;i++) { op=castesList.keys[i]; ddlCaste.options[ddlCaste.length]=new Option(castesList.values[i],op); } } }, function(val) { alert(val.get_message()); } ); }
i could call the webmethod, but i am getting this error in javascript.

I am trying to write a page that dynamically changes the options of one drop down based off the selected item in another one. I have varified the AJAX calls are happening correctly and vaified the root problem is that the new selected value of the dropdown is not being read during the AJAX postback. The code I am using is:
[Code]....
ddlGameName is the dropdown that the user selects from which calls the postback and then updates another dropdown. I can place a label in the updatepanel and assign the test as ddlGameName.SelectedValue.toString() and it will always read the first item in the drop down no matter which is selected. So how can I get it to read the updated selectedValue?
