Basicly i have created a database in access with 2 tables the secind table has a drop down with the field infor from the first.
Now when i link the database to the VB and insert the combo box in form the selecetion is not there?
What do i have to further deffine to appear?
I have a drop down, the drop down select values looks fine in mozilla but it doesnot show the full content in IE6 and 7,8.My Code
<td >
<asp:DropDownList id="drpttrainer" runat="server" Width="150px" OnSelectedIndexChanged="drpttrainer_SelectedIndexChanged" AutoPostBack="True">
[code]...
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.
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.
View 1 RepliesI'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:

I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model.

public class ListManagement

public IEnumerable<selectListItem> InactiveProduct { get; set; }
public string[] InactiveProductSelected { get; set; }
public IEnumerable<selectListItem> ActiveProduct { get; set; }

When the user navigates to a new page, this ddl's selected index is determined by a cookie, but if the ddl doesn't contain that cookie's value, then I'd like it to be set the 0. What method would I use for the ddl? Is a loop the best way, or is there a simply if statement I can perform?
This is what I've attempted, but it doesn't return a bool.
if ( !ddlCustomerNumber.Items.FindByText( GetCustomerNumberCookie().ToString() ) )
ddlCustomerNumber.SelectedIndex = 0;

how can i stylize drop down list? how can i add an empty first value ie "select campaign"
I have a page that has two drop down lists on it and a button. All controls sit in an update panel. The first drop down list (ddl1) contains a lot of values which caused a huge viewstate so I disabled viewstate on it. In the page oninit event I populate the drop down list every time the page is posted back. This all seems to work fine, it shows all the values and I can access the selected value in my event handler.
ddl1 has the autopostback attribute set to true so when its value changes the second drop down list (ddl2) is populated with some values that depend on the selection in ddl1. This also works fine, the values in ddl2 change when I select a value in ddl1.
ddl2 does not have viewstate disabled. The button that sits under my two drop down lists is disabled by default and becomes enabled when the value of ddl2 is changed to anything except string.empty. This is where I run into problems. ddl2 does an autopostback too but it seems to lose the selected index/value. When I'm in my code to check whether to enable or disable the button the selected index is always 0 and the selected value is string.Empty.
If I enable viewstate on ddl1 this all works fine. Could anyone point me to what I'm doing wrong?
Here is the code executed by the ddl2 postback:
