HtmlTextArea.Name Property


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets or sets the unique identifier name for the HtmlTextArea control.

Namespace:   System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

Public Overridable Property Name As String

Property Value

Type: System.String

A string that represents the value of the Control.UniqueID property.

Use the Name property to determine the unique identifier name for the HtmlTextArea control. In this implementation of the property, the get accessor returns the value of the Control.UniqueID property. However, the set accessor does not assign a value to this property.


The set accessor does not assign a value to this property because the Name property must have the same value as the Control.UniqueID property for the HtmlTextArea control to work properly.

Classes that inherit from the HtmlTextArea class may override this implementation, if necessary.

The following code example demonstrates how to use the Name property to select an HtmlTextArea control on a page and set its Valueproperty.

<%@ Page Language="VB" AutoEventWireup="True" %>
<%@ Import Namespace="System.Data" %>

  Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)

    ' Bind a data source to the Repeater control. 
    Repeater1.DataSource = CreateRepeaterSource()

  End Sub

  Sub Item_Bound(ByVal sender As Object, ByVal e As RepeaterItemEventArgs)

    ' The ItemDataBound event is raised when data is bound to an
    ' item in the Repeater control. Items can include the Header,
    ' Footer, and so on. Use the following logic only if the item 
    ' being bound is an Item or AlternatingItem.
    If (e.Item.ItemType = ListItemType.Item) Or _
       (e.Item.ItemType = ListItemType.AlternatingItem) Then

      ' The runtime automatically generates a unique identifier
      ' for each control embedded in a list control, such as the
      ' Repeater control. The Name property of the HtmlTextArea 
      ' control contains this unique identifier and is commonly used to 
      ' identify a specific control.

      ' Retrieve the HtmlTextArea control from the RepeaterItem.
      Dim area As HtmlTextArea = _
          CType(e.Item.FindControl("TextArea1"), HtmlTextArea)

      ' Insert a custom message for the fourth HtmlTextArea control by
      ' looking for a Name property that contains the number 3.
      If area.Name.Contains("3") Then

        area.Value = "Hello World"

      End If

    End If

  End Sub

  Function CreateRepeaterSource() As DataView

    ' Create a DataTable that contains sample data for the 
    ' Repeater control.
    Dim dt As DataTable = New DataTable()
    Dim dr As DataRow

    dt.Columns.Add(New DataColumn("Category", GetType(String)))

    ' Populate the DataTable with sample values.
    Dim i As Integer

    For i = 0 To 4

      dr = dt.NewRow()

      dr(0) = "Category " & i.ToString()


    Next i

    ' Create a DataView from the DataTable.
    Dim dv As DataView = New DataView(dt)
    Return dv
