I am building a ASP.NET 3.5 website, with WCF as the service layer. I have created an HTML table on the webform, and i am rendering a Drop down list inside it, embedded as in item template/
When i run it in IE7, it doesnot display the drop down boxes in the table. however, this works perfectly fine in IE8 or IE6.
Is there any known issue of compatability of IE7 with 3.5 webforms?
I have a View that renders something like this:
"Item 1" and "Item 2" are <tr> elements from a table.
After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the div marked as "Result of...".
I have some vague notions of JQuery. I know how to bind to the onchange event of the Select element, and call the $.ajax() function, for example.
But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.
Does anyone know how to do this so when I select something the 1st dropdown and the 2nd one becomes visible and populates list from a Select statement. I really need help on how to do in an aspx and not on the code behind page.

View 4 RepliesI have a gridview where i have two fields. one is product and second is sub category.
I need to do 2 things.
1. I need to populate the two combos from the database. But depending what is selected in dropdown 1 this will determine what needs to be populated in drop down 2?
how can i achieve this?
I have two dropdown linked with sqldatasources.When I select item in ddl1 then on the basis of selection ddl2 is being loaded.Is there any possiblity that if I select ddl2 then ddl1 will also load on the basis of selection?
View 3 RepliesI am a complete newcomer to ASP.NET. However in the few weeks I have been playing with it I have got pretty far and have mastered things like stored procedures, gridviews, formviews and templates.I have a dropdown box which is populated from SQLDataSource1
I have a second dropdown box which is populated from SQLDataSource2, but i need the query feeding this to be dependent on what was selected in the first dropdown box. I assumed it would simply be a case of modifying the select statement on SQLDataSource2 using the SelectedIndexChanged event on the first DropDownList to update the second SQL source, but I cannot work out for the life of me how to do it. Pretty much all of the code I have is ASP.
can i do this purely in ASP rather than using VB behind the scenes or do I need to use VB? I am pretty comfortable with vb.net but one of the other issues I have is referencing an ASP object from VB... so for instance if I had a text box in ASP, how can I read or change the properties of this object from VB?
FYI I am using Visual Studio 2010 and SQL/Server
creating a dropdown similar to the time dropdown in outlook, located in the recurring event. The dropdown shows intervals of 30 minutes based on a 12 hour time format and allows the ability to put text in it.

View 1 RepliesI'm having a problem with using a dropdown to filter the contents of another drop down. The basic idea is:
Dropdown 1 = CountryList (Column1)
Dropdown 2 = StateList (Column2)
I read the contents of a CSV file and populate the gridview. The user then visually verifies that the data is valid and proceeds to upload to the database. To do some testing, i have intentionally changed spellings of country names so they DO NOT match the countrylist which the grid view then flags with a different background indicating bad data. The user then edits the gridview. The Country and state columns then show a drop down control populated with the country list and filtered states list based on countryID.
Here's the ASP.NET ASPX Source for the section of code that is dealing with the gridview
[Code]....
Here's the section of VB Code behind that deals with handling the "RowEditing", specifically the binding of the dropdowns
[Code]....
The proglem is that these dropdowns are ment to easily fix minor errors in data. When i intentionally changed the spelling of "Canada" to Canadaa", this has no corresponding CountryID in the table and the ddlEdtStateID Dropdown's datasource filter does not work. I tried setting the datasource to nothing if a valid CountryID was not there and then i tried to use the SelectedIndexChanged event for the ddlEditCountryID to programmatically set the datasourceID for ddlEditStateID but when i try using CType(FindControl("ddlEdtStateID"), DropDownList) to set the DataSourceID, it does not find the control.
If the Country does not exist, then i just want the stateslist dropdown to say "select a country" but when a valid country is selected, it should display the filtered list for that countryID. Right now, if bad data is entered for the country, then the program crashes when it tries to populate the state drop down. I want it to just say, select a country when the countryID is not valid.
I have dropdown1 that has some items in it.I also have dropdown2 that gets populated from a database based on whatever is selected from dropdown1.Dropdown2 has its first item as "Make Selection" and then appends the data from the db based on what was selected in dropdown1.
Now when I select an item from dropdown1 it puts the correct data in dropdown2 but as soon as I select another item from dropdown1 it appends those values into dropdown2. How can I remove the values from dropdown2 after a new item is selected from dropdown1?
How to fill the value in drop down box according to value selected in another drop down box?

View 6 RepliesI am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.

is works fine in IE and the Markup validates for XML, but I cannot get firefox to render the XML as anything but the plain text.
<%@ Page Language="VB" ContentType="application/xml" AutoEventWireup="false" CodeFile="ShowXMLMessage.aspx.vb" Inherits="XML_ShowXMLMessage" Theme="" StylesheetTheme="" EnableTheming="false" %>
What I am dealing with is a collection of data from 3rd party sites, some xml, some thumbnail images already.I essentially have an asp page that uses vb to collected the data and display it with some minor formating in a <div>, I use a literal control and a stringBuilder to put together the html and output it to the literal.
Here is my asp.net code
<form id="form1" runat="server">
<asp:Literal ID="Info_literal" runat="server"></asp:Literal>
</form>[code]...
So what I've been trying to do without any luck is have the output dump into a stream, then render the html into an image from that stream.I have looked at most of the links that have been posted in simular threads, and none of those are simular to exactly what I am looking for.
I want to render my ASPX form in PDF
View 1 RepliesI have an ASP.NET application which calls aspx-pages in other ASP.NET applications (all on the same server and the same solution). This aspx-pages should be shown in a (fixed) region on the main-site in that way that that only the embedded pages is renewed, during user interactions there. Is an IFRAME the only way to achieve this goal, or can I use for example theAJAX update-panel or are there further possibilities / techniques?

I am developing website using xmlhttp request.I am using treeview control in a webpage.I am sending xmlhttp request to page for adding a treenode to treeview control.I added a node in the treeview control and i render the treeview control html using control.render method and send html to client through without postback.But i am not able to maintain the state of treeview control like selected node and expanded nodes.So I want to send state info to server through xmlhttp and how to update the state info in server,aslo i need to update the treeview control javascript objects like treeview_data which maintains the treeview state when i return back from server.

View 4 RepliesWhen developing custom controls and using them in ASP.NET, what are the answers to the following?
