#ACCESS MENU LIST LIKE .NET PROFESSIONAL#
If web form intrigues you, or the idea of creating appealing web pages excites you, you can consider seeking help from professional courses. It is very useful to provide a list of choices to the user and hence is one of the essential parts of a web form. From a simple google form to your application to a job profile, almost every type of form has a drop-down list. The DropDownList in ASP.NET is one of the most common features on web pages. L1.Text = "You selected: " + DropDownList1.SelectedValue Protected void Butt1_Click(object sender, EventArgs e) Protected void Page_Load(object sender, EventArgs e)

Unlike the DataValueField, the DataTextField is the text that is visible to the end-user.įor example, DataValueField can be the ID of the employees, stored in the database whereas DataTextField can be the name of the employees, visible to the user.Įxample Code for a DropDownList in ASP.NET
The DataValueField is not visible to the end-user. The DataValueField lets us set the name of the column as a value in the drop-down list. The “true” value indicates that the server is automatically notified about any changes in user selection of the items from the drop-down list. The AutoPostBack property comes with two choices, true or false to enable or disable the automatic postback. The Item property provides us with the collection of the items from the drop-down list. The DataValueField property binds the values of the datasheet or database to the drop-down list which is then visible in the dropdown list. The DataSource property is mainly associated with the Data Table or the Data Set and comes into action when you need to bind a database or datasheet to the drop-down list. The SelectedIndex property returns the index or the position of the selected item in the drop-down list. This property returns the text of the item selected in the drop-down list and hence is a very prominent property. ()Īs the name suggests, if we want to replace all the items in the drop-down list or if we want to clear everything and start afresh, the Clear() property lets us clear the entire drop-down list. The Remove() property has another form, i.e., when provided with the index (position) of an item in the drop-down list, it removes the element or the item by its position. The Insert() property helps us to add new items to the drop-down list at a specific position. The Remove() property lets us remove items from the drop-down list by their names. The Add() property lets us add items in the drop-down list by their names. The Count() property provides us with the total number of options or items in the drop-down list. The DropDownList starts and ends with a tag, similar to HTML. The second line to the fourth line describes the items in the list where an item with value -1 is visible to the user before clicking on it. The first line sets the ID of the drop-down list used to set the properties of this particular element, i.e., a DropDownList.
