I have two dropdowns menu in detailsview (Both one table) . I want to change items in the second dropdown when the user selects an item in the first dropdown.
What I did as following but it does not work :
Add an empty SelectedIndexChanged event on the first dropdown and then, bind the second to the first under Selectedvalue. Also, sat AutoPostBack="True" on first dropdown.
I have a horizontal menu control populated (in static mode: StaticDisplayLevels="1" MaximumDynamicDisplayLevels="0") from a site map.
I have another vertical menu control in the left toc of the page that I want to populate from the same sitemap but to be the children of the node selected in the first menu.
I am having slight trouble with the menu control on a website which I am developing. In IE 8 the text doesn't appear in the dropdowns. This is intermittent between two different nodes. :S I have added the z-index: 1000; fix, but it doesn't seem to have any effect. The site is currently here: watercress.lukestratton.co.uk , please don't pass the URL around. This is fine in ALL other browsers. I think it may be something to do with my CuFon font conversion scripts.
View 2 RepliesI've made a web page from the tutorials in "How do I" to link a menu to web.sitemap.
I build the site and no errors come up, the site opens in my browser, part of the menus work but the menu that links to the sitemap is not displaying the menu contents.
I've run the code on another machine and also made the code in VWD2010 and it runs as it should.
Un-installed and re-installed VWD 2008 and still no luck.
Think I might be missing some component?.
Im fairly new to .net so apologise if this is a simple request!

I got a web app linked to a SQL Server 2005. The registration page for learners on this page require a lot of information and many of them are on dropdown controls linked each to their own table adapter. The table adapters are linked to tables within the Database. The dropdowns consist of info like designations, grades, categories, race, etc. The tables like designations changes from day to day as new types of designations are added and the other removed. What will the best way be to add data to the dropdowns? Another way I considered are to have one table and add a field like a type field that distinguish between the dropdown so that I only use one table adapter, or are there a better way. Some Code:

I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.

<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AllowPaging="True" PageSize="10" OnPageIndexChanging="countryGrid_PageIndexChanging"

I've been trying to figure out the issue and knowone seemd to know. I put a dropdown on my page and when I view it from my server, it works fine. When I tell it to go and get it's values from a DB I can no longer see it on the page when I view it from the server. Here's the code I have for it:
<td
class="style28">
<asp:DropDownList
ID="DropDownList2"
runat="server"
DataSourceID="AccessDataSource1"
DataTextField="Team"
DataValueField="ID">
</asp:DropDownList>
<asp:GridView
ID="GridView1"
runat="server"
AutoGenerateColumns="False"
DataKeyNames="ID"
DataSourceID="AccessDataSource1"
EmptyDataText="There are no data records to display."
Visible="False">
<Columns>
<asp:BoundField
DataField="ID"
HeaderText="ID"
ReadOnly="True"
SortExpression="ID"
/>
<asp:BoundField
DataField="Team"
HeaderText="Team"
SortExpression="Team"
/>
</Columns>
</asp:GridView>
<asp:AccessDataSource
ID="AccessDataSource1"
runat="server"
DataFile="App_DataIRISBS.mdb"
SelectCommand="SELECT [ID], [Team] FROM [tblTeam]"></asp:AccessDataSource>
</td>
I have three parameters to search and the record is being populated on the gridview.
Paremeters are dropdown lists:
lstDepartment, lstSection, lstLocation
I used AutoPostBack to true for above dropdowns but the problem I am facing is when I select value in lstDepartment to show values in lstSection then gridview data refreshes and after that when I select lstSection to show values in lstLocation then again gridview refreshes.
What I want to do is to when I'll select dropdown one by one then gridivew display data when a Search button pressed.
I don't want to refresh gridview everytime on the basis of dropdown selection.
Using ASP.NET 2.0
I have a gridview populated by a SQLDataSource that is fairly complicated on a dataset changing constantly. It takes a second or so to fetch the data.
I want to have external dropdownlists for filtering the data that appears in the gridview, either with a FilterExpression or with parameters.
The problem is that querying the database to populate the dropdownlists takes a long time, because of the complexity of the query. The values in the dropdowns can vary based on other filters.
Is there some simple way of querying the database only once, for the main gridview, and then somehow querying the local (to ASP.NET) copy of the data to extract distinct values for populating the filtering dropdowns? I am thinking this might speed things up a bit.
I'm trying to link a detailview to a gridview. Both are using the same datasource control and it's coming from an Access database. Both are showing data. The gridview is listing products fine and the detailview is listing details of some default product (maybe the first). How can I configure the two so that when I hit my select button on my gridview that it populates the details into detailview with the correct data for the selected product?

I have 45 dropdown lists in my asp page. There are some methods that I can apply to all of these dropdowns. Is it possible to convert them into an array of dropdowns for ease of use?
View 2 RepliesSo I am using a formview that gets in Update mode with a bunch of values from a sqldatasource --- but I want to fill a couple dropdowns with data from the database --- but I cannot figure out how to bind the data to the dropdown box FIRST and then select the value in that dropdown box... but I keep getting an error that the Selected value is not a part of the dropdown (I assume because the sqldatasource is trying to bind BEFORE I can get the dropdown box bound).
IE -- when I load my values, lets say a 'Crop' comes back as 'Corn' ... I want to download the available crops from the database (ie. corn, beans, wheat, okra, etc.) and then set the selected value as CORN.... SO HOW do I get the dropdown filled BEFORE I try and bind the selected value?
i've 4 similar dropdowns in my form in four different categories, is there any way to bind one of them so that the remaining dropdowns can be automatically filled or binded with the same content as first dropdown
View 4 RepliesI have a gridview with a hyperlink control that allows the user to save pages to it (www.google.ca, asp.net, etc). Unfortunately it always adds the server name to the beginning of their link. [URL] I was wondering is there any way to change that within the control. or should I have it pass a query string to a url handler that will response.redirect them to their actual page?
View 3 RepliesI have a page with a datalist and a formview. The page holds a newsletter and access to archived newsletters. I have set up the datalist so that each item contains a button control with a bound text. The formview holds an object with a bound data attribute. I have the page running with linq and the intitial page populates perfect. What I need to do though is be able to click a button in the datalist and have the formview rebind to the correlating data.

I am working with a formview edititemtemplate. Currently in my page load, i have some stuff that would show or hide certain panels based on dropdownlist values. These dropdown values get binded during page load. I need to be able to change the values/dropdowns, without rebinding the old data, and updating the visibility of the panels based on predefined rules.
I have experimented with putting my formview.databind() in page load if isnotpostback, in prerender, in prerender if isnotpostback. I have tried my rules (ex if ddlState.selectedvalue = "DE" then pnlDelaware.visible = "true") in the page load, and the page render. I'm just not sure how to get the stars aligned here. The closest i have come is having the databind in the pageload if notispostback, and the rules in the prerender. However I get an error "dropdownlist has a SelectedValue which is invalid because it does not exist in the list of items.
I have a page with a data repeater. Each row has a dropdownlist for the user to select a value and the values in every dropdown are the same. I also have an SqlDataSource which each dropdownlist gets its values from as its created. Everything is working as it should but for each dropdown that is rendered a seperate call is made to the database.
suggest a better way for me to do this that means only one call to the database for all dropdowns rendered?
I'm a complete novice in .NET. I am trying to implement a multi textbox / dropdowns / checkboxes search for a website using vb.net. How do I pass the values of my form fields to my griedview and display the search result on the same page?
I've written a stored procedure and specified it as data source for my gridview and defined parameter source as my CONTROLS (textboxes, checkboxes n dropdowns) on the form. What I want is when a user fills out one or multiple fields on the form, how do I display data in the gridview on the click of SEARCH button? Also is it necessary to write a codebehind for my search button or we can achieve the desired result in some other way?
