Web Forms :: Dropdown Should Select The First Title
Aug 26, 2010
I have a dropdown that has datain the format "ID Title" sorted on the Title.
Ex data is
122343 Another Example
320078 Machines are fun
953278 This is an example title
145678 Welcome to my world
Now the data in the dropdown is becoming too large. And customers have to scroll down a lot to get to a specific title. What I am trying to do is give links above the dropdown (A, B, C, ...., Z, 0, 1, ...., 9). When A is clicked the dropdown should select the first Title that begins with A and so on.

In my application I have the following message:Object reference not set to an instance of an object.
@Html.DropDownList("Title",ViewData["PersonTitle"] as SelectList, Model.Person.Title)
The dropdownlist contains simple strings (person titles). When you select a title, that title should be returned to my model. Controller code:
ViewData["PersonTitle"] = new SelectList(new[] { "Dhr.", "Mevr." });
Why is this not working ? Edit: The purpose is to change
@Html.EditorFor(model => model.Person.Title)
into something like this
@Html.DropDownList("Title",ViewData["PersonTitle"] as SelectList, Model.Person.Title)

I'm using the code below to extract data from a gridview and populate it into textboxes for the days and two drop downs for Project and Category.
For some rows in the gridview everything but the category ddl populates correctly. If I click the row a second time the category ddl displays the correct category.
why I have to click twice for some rows?

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?

I have a drop down list with two options Score and status. On selecting score select score i display a MultihandleSliderExtender to select the score range ex: 10 to 20 and on selecting status i display dropdown list . On displaying one option i make the other as not visible.
Now comes the problem in Firefox (works properly in IE) when i select score and then try to change my option to status it does not allow me to do so i.e the mouse over event on the dropdownlist is not working.

I have a number of dropdown lists which are populated from a database. They load depending on what the previous dropdown selection was so for example if the system was car based and I had chosen Ford then the next dropdown list would populate all cars made only by Ford. What I'm wanting to do is add a select all to one of the dropdown lists. Does anyone know how this would be done?

I have a date list in DropDown and there is no blank item in it. Dropdown item seems to be following:
01-02-2010
02-02-2010
03-02-2010
04-02-2010
DropDown is bounded by sqlDataSource.
If 04-02-2010 is the last date for today then I want to display 04-02-2010 by default in the dropdown if the page load.
We are updating data on daily basis. So on next day the date will be 05-02-2010 so when the data updated then 05-02-2010 should be shown iby default in the dropdown.

I have a gridview with two columns (item templates) one is a dropdown and the other is a textbox. I need to select an item from the dropdown (which I can do) and then get the cost of it and then put the cost in the texbox item template of the gridview. So I think I need to pass the row number and cost_id of the selected item to a procedure to get the cost of the item. Here is my so far code that I have now Idea how to pass the values of the gridview and then pass the cost of the item back to the proper row and textbox of the girdview.

I have a DetailsView that binds a User's Profile data into an ItemTemplate upon the Page_Load. When the user chooses Edit Mode, all of the Data is correctly carried over, except for the DropDownLists selected values. If on the ReadOnly page, the user's data shows "Male" for the Sex, then on the edit Mode page, I would like the DropDownList that gets the sexes from the database ("male", "female"), to have automatically selected "Male" in the DropDownList, not the lowest indexed item.

I am experimenting with 3 dropdowns bound to 3 different datasources. I want the contents in each dropdown depending on what is selected from the above dropdown and the datasource queries reflect this.
<asp:DropDownList ID="DropDownList_CostCentres" runat="server" Height="16px"
Width="138px" DataSourceID="CostCentreDataSource" DataTextField="CostCentre"
DataValueField="CostCentreID">
</asp:DropDownList>
<asp:SqlDataSource ID="CostCentreDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [CostCentreID], [CostCentre] FROM [CostCentres]">
</asp:SqlDataSource>
<br />
<br />
<asp:Label ID="Label2" runat="server" Text="Manager:" Font-Bold="True"></asp:Label>
<br />
<asp:DropDownList ID="DropDownList_Managers" runat="server" Height="16px"
Width="138px" DataSourceID="ManagerDataSource" DataTextField="EmployeeName"
DataValueField="EmployeeID">
</asp:DropDownList>
<asp:SqlDataSource ID="ManagerDataSource" runat="server"
ConnectionString="<%$ ConnectionStrings:corkABCConnectionString %>"
SelectCommand="SELECT [EmployeeID], [EmployeeName] FROM [Employees] WHERE ([CostCentre] = @CostCentre)">
<SelectParameters>
<asp:ControlParameter ControlID="DropDownList_CostCentres" Name="CostCentre"
PropertyName="SelectedValue" Type="String" />
</SelectParameters>
</asp:SqlDataSource>
However, the second dropdown does not load with the relevant data when I select a value from the first dropdown (stays blank). Must I still provide an event handler and how do I combine this with the sqldatasource?

I have a dropdown list which is bound to a gridview. I would like to add a dropdownlist item which, when selected, will default to displaying ALL gridview rows. So I would like as the first dropdown list item "All Items" and have this as the default.

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)
