How To Access Drop Down Box From Jquery
Apr 18, 2010
Well, I have a really small problem. How can I access an ASP.NET Drop down list from jquery? I tried to use "CssClass" property of the drop down list to assign a CSS class and then accessing that list using that class, but later I found out that the class changes when an element is selected, so my initial class replaced by a new class.I set the "CssClass" property of that list to "InstrumentDropDown". When the page loads for the first time, its class property is set to "InstrumentDropDown", just as I expected. But when an element is selected, and a postback is made, it becomes something like "InstrumentDropDown sg selected" (may be there are underscore between words instead of spaces)
I also cannot use the "ClientID" property because the part of code that access that list is not inside the page, but in a separate javascript file.

I have a link button in a repeater control. the li element is drag and droppable using jquery. when the page loads the the link button works perfectly, the jquery that is attached and the server side code both execute. when I perform a drag and drop then click on the link button it doesnt not fire. when i click it a second time it does fire. If i perform 2 or drag and drops in a row the link button doesnt fire a as many drag adn drops as i before it will fire. for example if if perform 3 drag and drops then it will take about 3 click before the events are fired.

My scenario is to drag an item from a repeater/datalist to another repeater(preview repeater). The preview repeater already contains some icons in some positon(for eg. in 1st and 4th items). I need to insert the icon to empty positions(2nd, 3rd and 5th items) in preview repeater.

I have an .aspx file that has 3 drop down lists:
ddlMake
ddlModel
ddlColour
i have a Page_Load function but i cant acces them in the Page_Load function...
using System;
using System.Collections.Generic;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
namespace NorthwindCascading
{
public partial class _IndexBasic : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
CarService service = new CarService();
List<string> Makes = service.GetCarMakes();
ddlMake.DataSource = Makes;
ddlMake.DataBind();
ddlMake.Items.Insert(0, " -- Select Make -- ");
}
}
}
}
I have added the code-behind file manually so i guess i am missing something... it just says that the ddlMake element is not defined in current context.

Basically, I'm lookuing to get some performance feedback and peoples thought about speeding up performance of my cascading drop down boxes.
Current;y I'm using a acces.db on the backend to populate the date.
It's just non populating for what I think is fast enough.
Would it be faster if I put the data in a real database? mssql, mysql, etc...
I wouldn't think it was my code, It's not even that many lines.

I have a formview on my aspx page containing various controls arranged using table. There is a DDL "cboClients" which i need to enable or disabled depending upon role within Edit mode.
The problem here is that i am not able to get that control using FindControl() method.
I have tried following code -
DropDownList ddl = null;
if (FormView1.Row != null)
{
ddl = (DropDownList)FormView1.Row.FindControl("cboClients");
ddl.Enabled=false;
}
Even I ave used the DataBound event of the same control -
protected void cboClients_DataBound(object sender, EventArgs e)
{
if (FormView1.CurrentMode == FormViewMode.Edit)
{
if ((Session["RoleName"].ToString().Equals("Clients")) || (Session["RoleName"].ToString().Equals("Suppliers")))
{
DropDownList ddl = (DropDownList)sender;
ddl.Enabled = false;
}
}
}
But this databound event occurs only once, but not when formview mode is changed.

I was wondering if there is any way that I could have a null value (or any other static value) appear at the top of a drop down list which is then populated from an AccessDataSource.I need it so that users can select a tag for their post (within a social networking system) if they wish to post to a group page or they can simply leave the list as null to post to their profile.

For our next project (a small app in ASP.NET/C#) we have to create drag and drop zones in the UI so that components/widgets can be dragged and dropped and layouts can be changed dynamically (for example, the user should be able to switch between two-column to a three-column layout from the front end). After doing some searching, I got to know that there are two approaches: Use Web parts and Content-zones. Using jQuery.
I also learnt that jQuery approach is preffered, but I would like to know how can I create such zones in my application and also save these zones per user (in the D so that when the new request comes for that user their preferred layout is displayed? I basically want to know if there are some tutorials on creating persistable drag and drop zones using jQuery.

I am creating a cascading drop down control for use with some drop down lists. They are filled using datasets which connect to a MS Access database. The first dataset was no problem however now I need to create the second which contains a where clause using a passed parameter (ie the selected value from the first drop down). In examples I have seen on the web the @ symbol is used eg WHERE fubar = @varname
When I try to execute this in the query builder in VS2008 I get two errors:
Error in WHERE clause near '@'. Unable to parse query text.
Followed by:
Executed SQL Statement: SELECT DISTINCT tbl_frame.frame_name, tbl_product.frame, tbl_product.model
FROM (tbl_product INNER JOIN
tbl_frame ON tbl_product.frame = tbl_frame.frame_id)
WHERE(tbl_product.model = @model)
Error Source: Microsoft JET Database Engine
Error Message: No value given for one or more required parameters.
It never promts for a variable. If I change the query to be something like WHERE tbl_product.model = 7 it works.

I'm struggling with a web form where I have created one date field and couple of drop down lists. These drop down lists populate themselves from a backend MS ACCESS database file. My problem is that I am not able to make the two drop down menus dependent in a manner that when the first drop down menu is selected the second should be populated accordingly?
This is the code for the website form:

We have a site that is public facing, let's say it's http://www.example.com. When the SSL is implemented, [URL], I can no longer access the jQuery 1.4.3 file on my own server. Furthermore, after a tweak to the security setting, I was able to get past the 'Access is Denied' error, but the first call was null.I understand there is a problem with different protocols actually being within the scope of the cross-domain problem? Is that true? And if so, will this now require JSONP?

I have 2 dropdownlists, the second (department) cascades from the first (division). I use a jquery script to update the second drop down list. When the user clicks submit, the underlying model is updated, apart from the new value for department. 2 ideas I have for fixing this are; a) Generate a postback. Prefer not to do this because of bad user experience. b) With a JQuery change event, make a call to server side and set a ViewData variable that I can use to update the field in the model later.
However there must be a better way. This is the view;
