how to setup a edit option in the drop down...
Example:
I have a drop down for 6 colors...and user didn't find the color which he wants...can I place a last option as new or Edit or something which allows the user to enter the color he wants in the dropdown or change that drop down to textbox to enter data... If this is possibly then how can i capture those values in the code behind...
I have a listview that is displaying records currently based on a dropdown.. works great.. now, within those results returned, i would like to filter down some more.. How can i add a dropdownlist to the page that is populated with data from the listview(only 1 field would be used to create the list ) and if you chose to filter by that drop down, then the listview is revised to display only records with the selected value.
Example..
Currently you pick from a drop down.. Report#1, Report#2 or Report#3 Say report#1 returns 100 records.. and the field im going to be filtering on is my "Vendor" field.. so once my listview displays my results, a dropdownlist is populated with all the vendors that were returned with the query.. could just be a few..
Now you are sitting there paging thru all the records.. and realize you really just need to see out of the 100 records, records that belong to Vendor#3, so you pick #3 from the drop downlist and the procedure is called again now filtering on that vendor..
I have a dynamic dropdown that is populated from sql. The user is supposed to select an option from the dropdown, then click a search button on the form to return some results based on that selection. It works fine if the dropdown gets populated with more than one record. However, if only one record is returned, that one record can't be selected. Whether you select it or just leave it alone since it's the only one, when you click the form button (search button), no results are returned b/c the dropdown selection must not be actually selected.
I've included the relevant code below. First the DDL, then the datasource, and finally the C# code in the if (!Page.IsPostBack)
[Code]....
I am using database table as datasource for my dropdownlist. I want to add an extra item in my dropdownlist for example "select country".
how can i do that.. currently my code is:
dropdownlist1.datasource=dt;
dropdownlist1.datavaluefield="country_id";
dropdownlist1.datatextfield="country_name";
dt is a datatable , "country_id" & "country_name" are columns
I 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.
The example is given below( I am reading the book Sams Teach yourself ASP.NET 2.0 by Scott Mitchell. page 628)

I have a dropdownlist on my page that when a user selects an item sets the list for another dropdownlist. My problem is that no matter what the user selects in the 1st dropdown it resets itself to the first item in the list. I have autopostback=true and nableviewstate= true. Is there another setting i'm missing or is it my code?

how to make the IDE stop adding these extra elements? i changed the Target Schema to all possible combination and it didn't help.
Is there built in methods into .net framework to do the following:
Get role GUID from user name/user GUID
Get role name from role GUID
So far I have been sending queries to the asp_roles and asp_users tables to obtain that information and I'm wondering if there is a nicer way of doing this?
I have the following methods that I store in the ASPUtilities class:
getRoleGUID(guid userGuid) { LINQ joins }
getRoleGuid(string userName) { LINQ joins }
getRoleName(guid roleGuid) { LINQ joins }
EDIT:
I have just looked into extending SQLMembershipProvider examples.
Few examples completely override the SQLMembershipProvider, but I think what I'm interested is just adding few extra methods to deal with the roles by using LINQ. Is this feasible?
I have a list of options (IEnumerable< SelectListItem >) in my model that I want to use in multiple dropdowns in my view. But each of these dropdowns could have a different selected option.
Is there an easy way to simply specfiy which should be selected if using the Html.DropDownList helper?
At this point, the only way I can see is to generate the html myself and loop through the list of options like so:
[code]....
have a dropdownlist (ddl2) which is dependent on the selected value of another dropdownlist (ddl1).I have set the appendatabounditems to "true" for ddl2 and have added a "Please Select" and a "Select All" options. The Options show in the list when the page first loads. When ddl1 is selected the page refreshes and ddl2 is populated, however the "Please Select" and "Select All" options have disappeared.
View 7 RepliesI have an aspx page that has...
if (!IsPostBack)
{
PopulateBrand();
in the Page_Load. This PopulateBrand() simply populates my drop down. That works great and on post back it retains the value.
The problem I'm having is that there is also a link on the page that is posting back some parameters to this page. What is happening is that when this is clicked it's falling through this !IsPostBack section and wiping out my drop down values that I had selected and repopulating it.
How can I prevent this and just retain what I selected when this page is posting back to itself when the link is clicked?
Eg:-- When I type "A" all the elements starting with A should be displayed... If "B" then elements with B....etc)
Ex:
<asp:DropDownList ID="ddlLocation" style="width:140px" runat="server">
<asp:ListItem Value="1" >India</asp:ListItem>
<asp:ListItem Value="2" >India - Hyderabad</asp:ListItem>
<asp:ListItem Value="3">South Africa</asp:ListItem>
<asp:ListItem Value="4">Australia</asp:ListItem>
</asp:DropDownList>
javascript :
function DisplayText()
{
var textboxId = '<% = txtText.ClientID %>';
var dropdownListId = '<% = ddlLocation.ClientID %>';
document.getElementById(textboxId).value = document.getElementById(dropdownListId).value;
document.getElementById(textboxId).focus();
}
code behind :
ddlLocation.Attributes.Add("onChange", "DisplayText();");

View 1 RepliesI am new to LINQ but not >net. I do understand SQLDataSource, etc. I was just told by a coworker not to use a LINQ to SQL Class for my new project (Bank.dbml). I was told to use instead the ADO.Net Entity Data Model (bank.edmx).
BankModel.edmxBank.dbml
When only using ADO.Net Entity Data Model I try to associate a GridView with a new LinqDataSource I get no options. When I add a LINQ to SQL Class I get the option to use it but it is empty. Is this because all my LINQ classes are mapped in the ADO.Net Entity Data Model (bank.edmx)? Can someone tell me (or point me to) what the differences are in these two?

View 7 RepliesI have an asp.net application. I want to add a global.asax and global.asax.cs file to my project. In the IDE when I select to create a new global.asax file, the option to create a CS code behind file is greyed out. When the global.asax file is created, no code behind is created, instead code is placed in the global.asax file and the global.asax.cs file is never created? Why is the option for a C# code behind file greyed out?
