One Dropdownlist Filling Another And Displaying Results?
Feb 23, 2010
I have 3 tables:
1) I'd like to fill 1 dropdownlist with the STATE.Name and the other dropdownlist with the CITY.Name based on the STATE chosen, show up the cities, and after the city is chosen, the SUPPLIERS are shown.
2) Is it ok to make a foreign key field for State inside the City table ?
3) Is it better to create new fields STATE and CITY inside SUPPLIER ?
and when the value in the Database in null (""), it throws this error: ArgumentOutOfRangeException: 'pn' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
The 2 dropdownlist controls are-ddlCountry and ddlState. The 2 database tables are-Country and State Country table has fields named- C_ID(pk) and Country State table fields are-S_ID(pk), State, C_ID I'm able to bind the dropdownlist controls to the database. But I want the contents of ddlState to change according to the Country selected from ddlCountryI don't want to use ajax
how to implement Search and displaying results on same page using ASP.net webform and simple way to implement paging with Ajax. The top of the page should have the search criteria and once button clicked, it should display the result below with checkbox so that user can select and delete any / all of the search result.
<body> <form id="form1" runat="server"> <div> <asp:GridView ID="press_dl" runat="server" AutoGenerateColumns="False" PageSize="1" ShowHeader="False"> <Columns><asp:TemplateField><ItemTemplate> test head test shortnews </ItemTemplate> <HeaderTemplate> </HeaderTemplate> </asp:TemplateField></Columns> </asp:GridView> </div> </form> </body> Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If Not Page.IsPostBack() Then bind_press() ' bind_events() End If End Sub Sub bind_press() ds = Nothing ds = New DataSet Dim query As String query = "select top 1 * from tbl_press order by press_id desc" myConnection.Open() da = New OleDbDataAdapter(query, myConnection) da.Fill(ds, "Press") myConnection.Close() press_dl.DataSource = ds.Tables("Press") press_dl.DataBind() End Sub its dislpayes like this test head test shortnews test head test shortnews
i have an html editor where a user can put in some text.the thing is that when trying to display this text on a different page results in displaying the html that was saved by the editor.i want to display the text in a text box (if possible), with the special attributes(bold, itali etc.i currently get the text with the html tags.
I have a set of controls that enable the user to search one of two fields in a given SQL Server table. The ddlSearch dropdownlist specifies the field to search. The txtSearch textbox contains the search string. I have the following code working fine, except search string isn't being passed to my listview:
I tried adding a DataBind after End Using, but the listview still won't provide the search results. Note that I also have an EntityDataSource on page.
Am I adding this to the wrong event? Should this code be added to PageLoad instead of click event of Submit button? What other issues should I address? Is it possible for ListView to handle the search by itself? That is, do I even need other dropdownlist and textbox controls, or is there functionality builit into the listview control to search? Finally, can I enable a checkbox for each returned item? I will need this so that the user can select items to add to their order.
I'm working on a job seeking website where the job seeker can search for a job , the search box is located in the master page, that's why i passed the keywords as a query string, and then the matching jobs will be displayed in a listview.
the keywords will be taken from two controls: a drop down list which the user can choose the location of the job, and a text box where he can type a keyword.
the select command of the sqlDataSource of the data list is as the following:
Working in ASP.NET (VB), I am trying to develop a simple search results page for my website.
The process is as follows:
(1) The site's user enters a search phrase;
(2) The search results page searches the site's database, returns the page title as a link, and a short snippet from each search "hit", with the search phrase highlighted.
I already have the search part done, and also the "highlighted" part done (using Regex). However, I want to be able to return a short snippet of text, which include the search phrase (a few words before the search phrase, a few after). Something like:
I have created a search page using Visual Web Developer and Access as the database. Instead of displaying the results from the search in Gridview on the same page what would be the coding to pass the results to a new page titled "Search Results".
I am drawing a blank and need some direction.I am putting together a simple website that has a single DropDownList that is DataBound to table inside of a FormView Template.What I want to happen is when the page loads, it runs the SELECT statement and displays that result(which it does, so that part works).Where I am stuck is that if I Click the DropDownList and select another item, and display the results of that selected item in the associated Databound controls.My code is below;
on the form i have one dropdown and search button. Accroding to selected value of dropdownlist, on pressing search button user will see results in gridview.now in after the result is shown and user selects say page 2 then results are shown of page 2. But then if i select new dropdownlist value and press search, it shows result but directly goes to page 2(last time's page selected) instead of showing page 1....
I have a page with 2 dropdownlists on it. One of them shows a value when the page is opened, the other doesn't. Why? I would like for them both not to be showing anything when the form opens. The coding for them appears to be identical.
