{
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 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.
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.

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. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement { public IEnumerable<selectListItem> InactiveProduct { get; set; } public string[] InactiveProductSelected { get; set; } public IEnumerable<selectListItem> ActiveProduct { get; set; } }
I have two drop down list on a page. The first one list projects and the second list users.

I am trying to create an MVC List View that can be filtered by the value selected from a drop down list.
Selecting a value should repost the page ... Since there is no concept of view state data I am having some issues with this ... I can get the repost to take place but my drop down resets and I am not able to get the value that was selected.

I have tried many of the posts that refer to setting up drop down lists but can't set them up in the content because this is a List View.
I had ddl which in selected changed it execute some code but when i tried to do that it wasn't worked well WHEN i checked the reason i found that ddl in selected value =0 also i made all well and this is my code
protected void DDlProductFamily_SelectedIndexChanged(object sender, EventArgs e) { if (DDlProductFamily.DataValueField.Contains("ProductCategory_Id")) using (SqlConnection Con = Connection.GetConnection()) { SqlCommand Com = new SqlCommand("GetListViewByProductCategory", Con); Com.CommandType = CommandType.StoredProcedure; Com.Parameters.Add(Parameter.NewInt("@ProductCategory_Id", DDlProductFamily.SelectedValue.ToString())); SqlDataAdapter DA = new SqlDataAdapter(Com); DA.Fill(dt); DataList1.DataSource = dt; DataList1.DataBind(); } }
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;
I want to be able to have '0' (zero) for CampaignId for "--Select Campaign--" selection. Is this possible to specify 0(zero) for "--Select Campaign-- option instead of ""?
