Line break (Wrap) Text in ASP.Net ListView ItemTemplate using C# and VB.Net

Hi phonghue,

In your code you need to find itemPlaceholder Id instead of OPPubDescrip and use Label control.

Refer below sample.

HTML

<asp:ListView runat="server" ID="ListView1" OnItemDataBound="ListView1_ItemDataBound">
    <LayoutTemplate>
        <div id="itemPlaceholderContainer" runat="server" style="">
            <span runat="server" id="itemPlaceholder" />
        </div>
        <span style="color: #3366ff;"></span>
    </LayoutTemplate>
    <ItemTemplate>
        <asp:Label Text='<%#Eval("ParaGraph") %>' runat="server" ID="lblParaGraph" />
    </ItemTemplate>
</asp:ListView>

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataTable dt = new DataTable();
        dt.Columns.Add("ParaGraph");
        dt.Rows.Add("Welcome to ASPSnippets.com");
        ListView1.DataSource = dt;
        ListView1.DataBind();
    }
}

protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
    Label lblMessage = (e.Item.FindControl("lblParaGraph") as Label);
    string newString = "";
    if (!string.IsNullOrEmpty(lblMessage.Text))
    {
        newString = lblMessage.Text.Replace(" ", "<br/>");
    }
    lblMessage.Text = newString;
}

VB.Net

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim dt As DataTable = New DataTable()
        dt.Columns.Add("ParaGraph")
        dt.Rows.Add("Welcome to ASPSnippets.com")
        ListView1.DataSource = dt
        ListView1.DataBind()
    End If
End Sub

Protected Sub ListView1_ItemDataBound(ByVal sender As Object, ByVal e As ListViewItemEventArgs)
    Dim lblMessage As Label = (TryCast(e.Item.FindControl("lblParaGraph"), Label))
    Dim newString As String = ""

    If Not String.IsNullOrEmpty(lblMessage.Text) Then
        newString = lblMessage.Text.Replace(" ", "<br/>")
    End If

    lblMessage.Text = newString
