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,
Pero
