View 1 RepliesForms Data Controls :: How To Capture A DropDownList Selected Index Change Event
Sep 15, 2010I have a gridview that receives data based on selection from a primary dropdownlist object. Works.
Within the gridview, there is a dropdownlist whose selected index is based on the query from the primary dropdownlist. Works.
Problem.
How do I force the used to change whatever value that the dropdownlist contains after they make their initial selection from the primary dropdownlist; except the default value of "make a selection".
Gridview, contains a checkbox which drives whether a selected row is inserted into the data base. The databind in done using an ObjectDataSource on the presentation page, not in the code behind.

My problem is that when I click on a linkbutton than the one selected, it doesn't highlight the selected linkbutton, because postback has been initialized. Instead it highlights the linkbutton that I have specified in the Page_Load event.

C# - Disable Or Enable 2nd Dropdownlist In Aspx Based On Selected Choice Of The 1st Dropdownlist Box
Apr 15, 2010I am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:
<script type="text/javascript">
$(function() { var dropDownList1 = $('#<%= ddlUserType.ClientID %>');
var dropDownList2 = $('#<%= ddlMember.ClientID %>'); dropDownList1.change(function(e) {
if ( jQuery("#ddlUserType").val() != "ETOC") dropDownList2.removeAttr('disabled'); e.preventDefault();
else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );

what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:
<script language="javascript">
function CheckDropDownState(lstbox)
{
if (lstbox.selectedIndex == 3) { document.forms[0].ddlMember.disabled = 1; }
else { document.forms[0].ddlMember.disabled = 0; }
}

Web Forms :: DropDownList Doesn't Postback?
Sep 22, 2010I've created two datasources, one that gets a list of categories and it's id's and the other one get subcategories and it's id's. The categories are presented in a DropDownList and the subcategories in a ListBox. When choosing a category from the DropDownList the ListBox presents the subcategories of the chosen category. The subcategory datasource is set to get it's value for what category to get from the DropDownList's selected value.
My problem is that when I change the category in the DropDownList the subcategories doesn't update on a postback. Instead I have to press a button on the page that I know performs a postback to get the subcategories to update. What am I doing wrong here? I'm using this method on another page as well and when comparing them I can't find anything different. Any ideas?
Web Forms :: Link Goes To Next Page But Url Doesn't Change?

Now when I click that button it essentially goes to the right page in all ways but the URL stays as my default.aspx instead of changing to users/room.aspx?roomID=23423. I've tried it in IE and Firefox with the same results. Is this something I'm not understanding about Server.Transfer or why is this happening and how do I fix it?
Web Forms :: DropDownList Selection Doesn't Show?
Sep 29, 2010I've got two DropDownLists that are filled using a couple of SqlDataSources, like so:
[Code]....
The third DataSource, dsCriterias, is used to present a set of dynamically added DropDownLists depening on what's selected in the second DropDownList, subcategories. The set of dynamic DropDownLists are presented using this code:
[Code]....
The code works but there's little thing that's bugging me. When the page is first loaded the criterias belonging to the subcategory is not presented. I expect it to show the criterias but ther won't show until I make a choice in the categories-DropDownList meaning if I wan't the first subcategories criterias I have to choose different subcategory and then go back to the first one. It's a bit hard to explain.
An example: When the page is first loaded I get a category presented, eg. Vehicles. In the subcategories I get the alternatives "Bicycles", "Cars" and "Motorcycles". "Bicycles" will be the one presented when the page loads since the stored procedure used by dsSubcategories sorts the data by the subcategory names. The problem is that I don't get the criterias for the "Bicycles" subcategory at page load. To get them I first need to select "Cars" or "Motorcycles" and then choose "Bicycles".
I've tried putting a subcategories.SelectedIndex = 0 in in the OnLoad but nothing seems to do the trick.
