Access :: Populate Dropdown Only With Values Related To Other
Nov 5, 2010
I have an improvised system to enter data, below the gridview. I need to populate one dropdown only with the values which relate to the value selected in the drop down before that. For example. I have a dropdown for Customers and another for ShipTo. I want Shipto dropdown to populate only with the values which relate to the particular Customer selected.

I've spent a lot of time trying to figure out how to do a drop down for filters. Right now I have two filters as a textbox but I want a dropdown list instead as I would be adding few more filters. This is my index page:
Task List
<ul>
<% using (Html.BeginForm("Index", "Task"))
{%>
<fieldset>
<legend>Filters</legend> [code].....
This is the change I made in my Model:
public class FilterViewModel
{
public PapClientProfile Client { get; set; }
public PapStaff Physician { get; set; }
[code]...
But I'm not able to populate any dropdown values.

I'm stuck with a problem to populate a DropDownList control with values from the database using item field template in read only mode. since I'm new to ASP.NET. Below is the code and the error I'm getting:
'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.ArgumentOutOfRangeException: 'PictureReadOnlyCategories' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value
The code for this is :
<asp:SqlDataSource ID="categoriesDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand ="SELECT [CategoryID], [Name] FROM [Categories] WHERE ([UserId] = @UserId)">
<SelectParameters>

I have an application as: SelectCommand="SELECT [CategoryID], [Name], [UserId] FROM [Categories] WHERE ([UserId] = @UserId) ORDER BY [Name]">
</asp:SqlDataSource>
Pick a category: <asp:DropDownList ID="categories" runat="server" AutoPostBack="True"
DataSourceID="categoriesDataSource" DataTextField="Name" [code]...
When i take away the <SelectParameters>
<asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" />
</SelectParameters> and ([UserId] = @UserId), the dropdown list control will populate values from the database but when i live those 2, it won't populate any value from the database. When i remove the <asp:QueryStringParameter Name="CategoryID" QueryStringField="ID" />
</SelectParameters>,and live ([UserId] = @UserId), i get the error : Must declare the scalar variable "@UserId".

Errors are as follows:
Error 3 A field initializer cannot reference the non-static field, method, or property 'CompleteRentalls.completedb.sqlString'
Error 5 'CompleteRentalls.completedb.da' is a 'field' but is used like a 'type'
Can anyone help me rectify the above code such that the query results are returned to my datatable?

Just upgraded to VWD2010. I created a skin file and put it in App_Themes. I created a skin id for a couple of controls: gridview, dropdown etc. Normally in the properties you can go to skinid and a drop down with the skin id shows up and you can select it. Thats not happening. Also, if I put my skinid in for the skinid property of the component its not displaying the formating at all. For example: Here is what I have for a gridview in my skin file named /App_Themes/Default/Default.skin

i've run into small problem, here's the thing: i've got a dropdown list (ddlist1) that i am populating from a database, that works fine. However, depending on the option selected here, i need to populate another dropdown list (ddlist2). for example, if on ddlist1 i select option 1, on ddlist 2 i should get a list of options related to option 1 from ddlist1. If i select option 2, on ddlist 2 i should get a list of options related to option 2 from ddlist 1. and so forth. this information with which ddlist needs to be filled, comed from another database. o how can i go about this? m not sure yet how to code the second ddlist.

Scenario is .If a single value is retrived from the database then I think no need to populate the promt text. It may populate only that value and call the next function from the inside of it. Can it be possible using web methods.

I have a dropdown list with the names of the months listed in it. These names are stored as int values but converted to string for display purpose. I also have a RadDatePicker control that will allow the user to select a specific date to overwrite the default date. The default date in the textbox needs to be set to the last day of the month selected (i.e. May 2010 would default to 05/31/2010).

I wanted to know the best practice for caching data. Say I have some control example a dropdown list which is populated from my db. Now this dropdown is global and used across many pages. I was thinking of not going to database everytime to fetch data for this dropdown and put the result in Cache. And then populate this dropdown from cache. Is this a good practice or if there is another approach. Can I store my datareader in cache and then use it globally. Also could I do this in application start event?
