How to get item selected in dropdownlist

I'm searching and trying now for the last couple of hours, so I thought the community might help.I'm filtering the rows in a gridview using a ddlDate. Now, I want to request this selected item.But: When I load the page without clicking in the DropDownList, the ddlDate.SelectedValue is empty, and the ddlDate.SelectedItem.Text.ToString() gives a NullReferenceException.Is there any way to fix this without using a listbox?

Howto add selected item from dropdownlist to a textbox on the same form?


 I have been trying to figure out what the proper method is to be able to have a dropdownlist on the same form that holds a number of textboxes for properties. I am using a strongly typed typed view which was generated by the Visual Studio IDE so it contains textboxes for all of the properties of my strongly typed class.  The class has a few properties that can have a set of possilbe answers; I'd like to displat those possible answers in a dropdownlist and then when the user fills in the form and clicks the submit button the selected item would be transferred to the correct property. I have a solution but think there must be a better solution out there and was wondering if anyone might point me in the right direction.

So say I have a model with 3 properties, FirstName, LastName. and MaritalStatus.

If I generated a view for this then I'd get an aspx file with the following:


    <% using (Html.BeginForm()) {%>
        <%: Html.ValidationSummary(true) %>

            <div class="editor-label">
                <%: Html.LabelFor(model => model.FirstName) %>

ASP.NET 4.0 Menu Top Level selected item style


I want to apply a css class to the level 1 menu item (parent) when it or any or it's children are selected.

I've looked at MSDN documentation and any number of examples and walkthroughs but I haven't come up with a way of managing this. I was thinking something like this might work but the style is not being applied to the parent. To further complicate matters, if I try to apply a css style to StaticSelectedStyle it doesn't pick it up at all.

Menu Markup:

<StaticSelectedStyle  Font-Bold="True" ForeColor="#3333CC" />

Code Behind:

        protected void MenuItemClick_NavMenu(Object sender, MenuEventArgs e)


            MenuItem parentItem = e.Item.Parent;

            if (parentItem != null)


                parentItem.Selected = true;

dropdownlist - default value is not 'selected value'

i have created a dropdown list that is populated from a sqlserver datasource. i have a separate sql command which uses the dropdownlist.selected value as a parameter and returns the command value to a label.  it mostly works fine but with one problem. when the page loads, the label value is null, because it doesn't seem to treat the dropdownlist default value as a selected value. when i use the dropdownlist to select a value, this is fine and the label begins to display the expected value. is there anyway I can make the default value when the page is loaded act like a manually selected value, so the label control never displays a null value?

How to update selected item state in the list box by clicking a button?

I created a listbox menu to browse through content by clicking items in the listbox. I also created ‘back’ and ‘forward’ type of navigation to browse through the same content based on the browsing history. I load content into frame and accessing the browsing history with NavigationCommands.BrowseBack and BrowseForward Properties. It is working great. However, I need to indicate a selected state of the listbox item related to the content shown in the frame while browsing with Back/Forward buttons. I have a hard time binding that property. What is the correct way to bind selected state of the listitem in this case? Thank you in advance.
