I want to disable every fifth item in a dropdownlist.
dropdownlist1.items[i].Attributes.Add("disabled","disabled");
How do I write the logic to disable every fifth item in a Dropdownlist?
I am using two for loops: one for displaying items and one for disabling items in dropdownlist. How can I simplify my code?
I am trying something apart of my boundries, is there any way to disable a single intem in dropdownlist or stop the ddl change event for a single item.
View 2 RepliesI have a project that queries a set of times from a database and uses these entries to populate a dropdownlist. Once the page is loaded, the user can select one of the items in the DropDownList. When the "Save" button is clicked, the Selected item value is returned to the [HttpPost] version of the controller action. This item is then stored into session. If the system returns to the page containing the dropdown, I want the saved Value to be selected in the DropDownList. What actually happens is that the DropDownList is always set to be the first item in the list.
Database Table: This data has been imported using Link to SQL
[code]....
I bind dropdownlist in my page
protected void Page_Load(object sender, EventArgs e) {
BindDropDownList(DDL1, "city1", "name", "ID");
DDL1.Items.Insert(0, new ListItem("select city", "0"));
}
And SP
LTER procedure [dbo].[city1]
as
begin
select id,Name
from city
end
And design code
<asp:DropDownList ID="DDL2" runat="server" CssClass="daddsd">
</asp:DropDownList>
And here is imagebutton code that when click on it update data into table
protected void ImageButton_Click1(object sender, ImageClickEventArgs e) {
string data = Server.UrlDecode(Request.QueryString["BehCode2"]);
SqlCommand _cmd = new SqlCommand("insertinfo", _cn);
_cmd.CommandType = CommandType.StoredProcedure;
_cn.Open();
[Code] ....
Here when i click on button it insert all data into table but it didn't insert my selected item from dropdownlist it insert select city that i define in page_load
DDL1.Items.Insert(0, new ListItem("select city", "0"));
And when i delete this code from page load it insert in table first row of my table it didn't insert my selected item from dropdown list.

I 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(); }
} );
</script>
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; }
}
</script>
and thew .aspx code: <asp:dropdownlist id="ddlUserType" runat="server" onclick="CheckDropDownState(this);"></asp:dropdownlist>

In an ASP.NET 2.0 project I've got a RadioButtonList. I'd like to disable one of the items in this list, but when I change the Enable property of an item to false it just wrappers the item with a span instead of disabling the Input when rendered to Html:
<span disabled="disabled">
<input id="ctl00_RadioGroup_2" type="radio" value="OK" name="ctl00$RadioGroup">
<label for="ctl00_RadioGroup_2">Ok</label>
</span>
This works Fine on IE9 but on FF4 the radio button is still enabled. Or is the only way would be some Javascript?
Simple but weird? problem. I simply want to "disable" some asp.net dropdownlists
<asp:DropDownList Enabled="false" CssClass="DropDownGrade" ID="DropDownListMGP" SelectedValue='<%# Bind("[MGP]") %>' runat="server">
<asp:ListItem>1.00</asp:ListItem>
<asp:ListItem>1.25</asp:ListItem>
<asp:ListItem>1.50</asp:ListItem>
Enabled="false" don't work in the first place.My jquery code doesnt work either:
$('.DropDownGrade').attr('disabled', 'disabled');
i have a webpage that loads data into a gridview and refreshes the gridview every few seconds. I do this via a asp:Timer which runs a C# function every few seconds to requery the database and databind the gridview.
I also have a few dropdown lists to filter data from the gridview. These dropdown lists get their data from the same dataset as the gridview (e.g. if the gridview shows the stats of all apples being plucked from trees, then the list may contain e.g. all distinct apple types). How i refresh these dropdown lists is again to requery the dataset and reset the selected index to be one selected at time of refresh. So this causes a problem where the timer is up when the dropdown list is open - the index on the dropdown list is selected and refreshes the gridview, the dropdown list also refreshes with the current selected index and closes.
So the question i have how to disable my timer refresh from going off while the dropdown lists are active - or maybe how do i do this better?
i want the code to disable default selection in dropdownlist in asp.net and also on selection of a particular data field the values are displayed in the txtbox below.the dropdown should be filled with system related data like eg c:drive, d ... etc dynamically at run time.

View 12 RepliesIs there anyway to disable a textBox's validation(RequiredFieldValidator) base on the selection of dropDownList ?
View 5 RepliesI have a dropdown list for the which values are coming from DB. There is one option name OTHER, when I select other the textbox appears. For that Textbox I have made a required field validator. Till here it works fine. But when I select any other option, still it gives me validator errors. It should not happen. It should only give me required field error when the user doesn't fills the textbox on select of OTHER option. Please see the code.
Dropdown and Textbox code:-
<asp:DropDownList ID="ddlGraduation" runat="server" CssClass="txtfld-popup_drp"></asp:DropDownList>
<asp:RequiredFieldValidator CssClass="error_msg" ID="reqGraduation" runat="server" ControlToValidate="ddlGraduation"
ErrorMessage="Please select graduation details" InitialValue="--Select--" SetFocusOnError="true"></asp:RequiredFieldValidator>
<asp:TextBox ID="txtOther" runat="server" CssClass="txtfld-popup_p"></asp:TextBox>
<asp:RequiredFieldValidator ID="reqOther" runat="server" ControlToValidate="txtOther" ErrorMessage="Please specify your qualification"></asp:RequiredFieldValidator>
JS code for hiding and show the textbox when user select and deselect the OTHER option from dropdown list:-
<script language="javascript" type="text/javascript">
function pageLoad() {
$('#ctl00_ContentPlaceHolder1_txtOther').hide();
$('#ctl00_ContentPlaceHolder1_ddlGraduation').change(function () {
if ($(this).val() === "Other") {
