    Hi,

    I'm having a problem. I want to put info from a database in the title of a dock, but I can't do that.
    I tried the following example, but it gaves a parse error, because it's not possible:

    <

     

    telerik:RadDock ID="RadDock2" runat="server" Title="Conteudos da Tag '<%# Eval("Nome")%>'" EnableDrag="false">

     


    ...
    </telerik:RadDock>

    How can I solve this problem?

    Hi Cátia

    I think what you are trying to do will only work in a Databound control such as a repeater.

    Can you post the full code of the page and I can show you how to set the title dynamically in the code behind.

    Thanks,

    Ronan

    Ok. Here´s the code of the entire dock and the grid that is inside the dock. But I just want to change the title of the dock using data from the database.

    <%

    @ Control Language="C#" AutoEventWireup="true" CodeFile="conteudosTag.ascx.cs" Inherits="conteudosTag" %>

     

    <%

    @ Register Assembly="RadDock.Net2" Namespace="Telerik.WebControls" TagPrefix="rad" %>

     

    <%

    @ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

     

    <%

    @ Register Assembly="RadGrid.Net2" Namespace="Telerik.WebControls" TagPrefix="rad" %>

     

    <

     

    asp:SqlDataSource ID="GET_CONTEUDOS_TAG" runat="server" ConnectionString="<%$ ConnectionStrings:lms_bibliotecaConnectionString1 %>"

     

     

    SelectCommand="SELECT * FROM [NL_LMS_BIB_conteudos] INNER JOIN NL_LMS_BIB_temas ON

     

    NL_LMS_BIB_conteudos.IDTema = NL_LMS_BIB_temas.IDTema INNER JOIN NL_LMS_BIB_tipos ON NL_LMS_BIB_conteudos.IDTipo = NL_LMS_BIB_tipos.IDTipo INNER JOIN NL_LMS_BIB_users ON NL_LMS_BIB_conteudos.IDUserAutor = NL_LMS_BIB_users.IDUser

    WHERE NL_LMS_BIB_tags.IDTag = @tag">

     

    <SelectParameters>

     

     

    <asp:ControlParameter ControlID="Literal3" Name="tag" PropertyName="Text" Type="String" />

     

     

    </SelectParameters>

     

    </

     

    asp:SqlDataSource>

     

     

     

    <asp:Literal ID="Literal3" runat="server" Visible="false"></asp:Literal>

     

     

     

    <telerik:RadDockZone ID="RadDockZone2" runat="server" Width="70%" >

     

    <

     

    telerik:RadDock ID="RadDock2" runat="server" Title="Contedos da Tag x" EnableDrag="false">

     

    <

     

    ContentTemplate>

     

     

    <telerik:RadGrid ID="ConteudosTag" runat="server" OnItemDataBound="ConteudosTag_ItemDataBound" AllowPaging="True" AllowSorting="True" DataSourceID="GET_CONTEUDOS_TAG" GridLines="None" AutoGenerateColumns="false" PageSize="10" ClientSettings-EnableRowHoverStyle="True">

     

     

    <MasterTableView CellSpacing="-1" DataSourceID="GET_CONTEUDOS_TAG">

     

     

    <PagerStyle Mode="NextPrevAndNumeric" PagerTextFormat="{4} Pgina {0} de {1}, itens {2} a {3} de {5}" />

     

     

    <Columns>

     

    <

     

    telerik:GridHyperLinkColumn

     

     

    DataNavigateUrlFormatString="/lms_bd/FichaConteudo.aspx?conteudo={0}" DataTextField="Titulo" Target="_self" DataNavigateUrlFields="IDConteudo" UniqueName="Titulo" HeaderText="Ttulo" SortExpression="Titulo" />

     

    <

     

    telerik:GridBoundColumn

     

     

    DataField="Nome" DataType="System.String" HeaderText="Autor" SortExpression="Nome" UniqueName="Nome"></telerik:GridBoundColumn>

     

    <

     

    telerik:GridHyperLinkColumn

     

     

    DataNavigateUrlFormatString="/lms_bd/conteudosTema.aspx?tema={0}" DataTextField="Tema" Target="_self" DataNavigateUrlFields="IDTema" UniqueName="Tema" HeaderText="Tema" SortExpression="Tema" />

     

    <

     

    telerik:GridButtonColumn ButtonType="ImageButton" ImageUrl="~/imagens/page_white_put.png" ItemStyle-HorizontalAlign="Center" HeaderText="Descarregar"></telerik:GridButtonColumn>

     

    </

     

    Columns>

     

    </

     

    MasterTableView>

     

     

    </telerik:RadGrid>

     

     

    </ContentTemplate>

     

     

    </telerik:RadDock>

     

     

    </telerik:RadDockZone>

     



    In the .cs file I have this code, but perhaps this is not very important:

    using

     

    System;

     

    using

     

    System.Data;

     

    using

     

    System.Configuration;

     

    using

     

    System.Collections;

     

    using

     

    System.Web;

     

    using

     

    System.Web.Security;

     

    using

     

    System.Web.UI;

     

    using

     

    System.Web.UI.WebControls;

     

    using

     

    System.Web.UI.WebControls.WebParts;

     

    using

     

    System.Web.UI.HtmlControls;

     

    using

     

    Telerik.Web.UI;

     

    public

     

    partial class conteudosTag : System.Web.UI.UserControl

     

    {

     

    protected void Page_Load(object sender, EventArgs e)

     

    {

     

    string thisTag = Request.QueryString["tag"].ToString();

     

    Literal3.Text = thisTag;

    }

     

    protected void ConteudosTag_ItemDataBound(object sender, GridItemEventArgs e)

     

    {

     

    if (e.Item is GridPagerItem)

     

    {

     

    Label lblPageSize = (Label)e.Item.FindControl("ChangePageSizeLabel");

     

    lblPageSize.Text =

    "Itens por pgina:";

     

    }

     

     

    }

    }


    Hope you can solve my problem!

    Hi Cátia,

    If you want to use a custom title for the RadDock, the TitlebarTemplate should be used. It can be specified either dynamically by setting the TitlebarTemplate property to an instance of a class that implements ITemplate, or at design time. I have implemented a sample project (it is attached to the thread) that specifies the TitlebarTemplate at design time and updates its content dynamically by retrieving information from a database.

    If you have any further questions, please do not hesitate to contact us.

    All the best,
