AJAX :: Cascading Dropdownlist Maintain Selected Values?

Jun 10, 2010

I'm wanting to maintain the dropdownlist values that were selected when i use postbackurl with a button. They cascading dropdowns are on a masterpage in an accordion pane. I select the 3 vales in the ddl and then presss a button which redirects to the new content page.

I've been able to get the values using previousPage.master.fincontrol... but am then setting the selectedValue in the page_init of the conent page, but they aren't set when the page loads... does anyone know where to put the code to set the values?

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:

AJAX :: Cascading Dropdown Selected Value Not Working?

Feb 9, 2011

I have a web form where I have three dropdowns for Country State And City and there corresponding

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:

AJAX :: Cascading Dropdowns After State Is Selected

Aug 13, 2010

I have 3 dropdowns in my VB.Net 3.5 web app. After a user selects a value from the first (let's call it Countries) the second (called States) should populate correspondingly. Dropdown three (cities) should also cascade down after a State is selected. The Countries and States dropdowns have SQL DataSources. The Cities dropdown has to call 2 procs (based on the selected State value) so it does not have a SQLDataSource. My question is, the code below works for Countries and States, however, I cannot ge the Cities to populate...

<asp:DropDownList ID="drpCountries" runat="server" DataTextField="CountryName" DataValueField="CountryId" DataSourceID="sdsCountries" AutoPostBack="true">
<asp:SqlDataSource ID="sdsCountries" runat="server" ConnectionString="<%&#36; ConnectionStrings:MyConnectionString %>"
SelectCommand="SELECT * FROM [Countries] ORDER BY [CountryName] ASC"></asp:SqlDataSource>
<asp:UpdatePanel ID="updStates" runat="server" UpdateMode="Conditional">
<asp:DropDownList ID="drpStates" runat="server" DataTextField="StateName" DataValueField="StateId" AutoPostBack="true" DataSourceID="sdsStates">
<asp:AsyncPostBackTrigger ControlID="drpCountries" EventName="SelectedIndexChanged" />
<asp:SqlDataSource ID="sdsStates" runat="server" ConnectionString="<%&#36; ConnectionStrings:MyConnectionString %>"
SelectCommand="SELECT * FROM [states] WHERE StateId = @StateID ORDER BY [StateName] ASC">
<asp:ControlParameter ControlID="drpCountries" Name="StateID" PropertyName="SelectedValue" DefaultValue="" />


<asp:UpdatePanel ID="updCities" runat="server" UpdateMode="Conditional">
<asp:DropDownList ID="drpCities" runat="server" DataTextField="CityName" DataValueField="CityId" AutoPostBack="true">
<asp:AsyncPostBackTrigger ControlID="drpStates" EventName="SelectedIndexChanged" />
Protected Sub drpStates_DataBinding(ByVal sender As Object, ByVal e As System.EventArgs) _
Handles drpStates.DataBinding
' Call some procs and get a DataSet
drpCities.DataSource = ds

AJAX :: Cascading Dropdownlist Using JQuery

I am referring to following line from this link [URL] ....

In your code. i tried using this code and facing a tiny problem. In above mentioned code 'ddlContinents.ClientID'.val stores integer value in contentId for obvious reasons but the requirement of my code is different. i want to pass text which is selected instead of id no.for example if mumbai is listed as second option and i select mumbai it should store mumbai in contentId instead of 2 i.e. integer value.

AJAX :: Way To Use Two Cascading Dropdownlists With The Same Values

Mar 15, 2010

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)

AJAX :: Cascading Dropdownlist Has A SelectedValue Which Is Invalid?

May 20, 2010

I think this needs to be a sticky since this is not solved anywhere that I have been looking... I have been googling this for a while now and came across the answer by shear luck and a simple typo when I was writing the code...

Problem: I have 2 dropdown lists...

ddllist1 and ddlist2... Both are code-behind populated via a sql DB.

they are cascading lists via the ajax control.

I am trying to dynamically populate them with values from a DB for edit reasons.

When I try to get them populated I kept getting the error...

"dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items"


1) get the values from the DB or from where ever...

2) create a sql select to get the values from the ddl db

3) set the ID of the first DDL control to cddcontrol1.SelectedValue = id (this is a number)

4) set the value of the DDL to the string value ddlist2.SelectedValue = value (this is a string)

here is the code.
