View 4 Repliesin my asp.net and vb code web. i have a drop downlist and a text box.
when i select the item from dropdownlist the numeric value should change accordingly. is it possible
in above code works fine if every textbox disable/enable depending upon the dropdown list selected value, in my query i want effects only one textbox
in my query i have gridview with 1 dropdown list ddl, two texboxes tb1 and tb2.
tb1 is in visible false..
tb2 is in visible true.
if i select dropdown selected value as "other" tb1 column should be visible and ddl selected value not effected to another textbox tb2.
first i'll describe my problem:
I have payment form with a clients dropdownlist that is populated from a database on form load with:
value field = clientIdtext field = nameId
<asp:DropDownList ID="selClients" runat="server">
</asp:DropDownList>
When user makes a payment, it's necessary to chose a client from selClients, and so i get the clientsId value and build my insert SQL query.
Until here, no problems.
The problem with my UI has started since i had a lot of clients been registered: My dropdownlist became huge and it's taking too much time to load it's contents on page load. Also the dropdownlist area is taking a large area from page screen.
So i tryied a solution with jquery autocomplete plug in. I put a textbox with autocomplete for client name and another hiddenfield to receive the clientId when user select a item.
That solves both problems:
No more large amout of data loaded on page loadThe dropdownlist doesn't take a large area from page screen
But it gave me another problem!
With a textbox, there is a possibility for wrong input client name. So if i don't have a valid clientId in hiddenfield, it will generate a database INSERT exception because it doesn't respect the client table constraint:
payment table REFERS client table
I'm trying to find kind of dropdownlist where the user can type text with autocomplete. Like this, the user will be able to select only data within the possibilities of the dropdownlist and i always will have a valid clientId.

View 3 RepliesHow do i make the default entry in a dropdownlist not selectable? Right now I have a drop down and the users are able to select the default option that says (Select one)...here is what my code look like. I hard coded my options in there cause the list is really short and won't change ever. Right now, users can select the default entry and add it whatever list they are generating on the page...and I would like to make that default visible but not selectable.

SqlConnection conn = new SqlConnection("Data Source= EN\SQLEXPRESS;" + "Initial Catalog=ms;Integrated Security=SSPI");
SqlDataAdapter adapSel;
string mySQL = "SELECT '" + dd_list.SelectedValue+ "' FROM examtimetable ";
adapSel = new SqlDataAdapter(mySQL, conn);
conn.Open();
DataSet dsSel = new DataSet();
adapSel.Fill(dsSel);
GridView1.DataSource = dsSel;
GridView1.DataBind();
conn.Close();

Previously I have bind 7 column name in my dropdownlist

View 1 RepliesI have a FormView with an EditTemplate.And the EditTemplate contains an ascx control:
<asp:FormView
ID="fvTicketUpdate"
runat="server"
[code]...
The contents of the ascx control has TextBox and DropDownList controls binding to the results of the FormView's ObjectDataSource through Text='<%# Eval("field1") %>'and SelectedValue='<%# Eval("field2") %>'.This works fine and I have been building all of my front end pieces like this as <asp:Panels> rendering as FieldSets that go 100% across the screen.And we call these areas "strips" accross the screen.But now I've run into a problem.One TextBox and one DropDown bind fine to a Ticket Object.But the DropDownList that works has its <asp:ListItems> hardcoded before hand.Now I have DropDownList that gets populated through a WebService in the ascx's
code behind like this:
public partial class UserControls_FormControls_PntipUpdtFaaInfo :
System.Web.UI.UserControl
{
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
[code]...
The Problem I think is the FormView is trying to do its Bind to the objectDataSource before its child ascx control is loaded in the Edit Template.And I am getting this error:
Databinding methods such as Eval(),XPath(),and Bind() can only be used in the context of a databound control.Meaning that the control must already be databound to bind the selectedValue to a Property of the TicketObject.Is there an easy way to force the order of loading to make the PntipUpdtFaaInfo control load and have its Page_Load execute and bind ddlEquip before the FormView does its first dataBind and executing its Evals?Otherwise I have to take out the eval on the ddlEquip SelectedValue attribute and go to the Parent Page and hack and force everything to happen when it needs to.This layout has worked out well for me.All of the ascx area strips across the screen share the same Validation Summary for example.It allows me to think about one section at a time and the Properties to the Business Obect and CRUD methods as I go.But this is a big brick wall I've hit.
I will get required data from the web method that returns as table!!!
