asp.net Web server control with child controls, event not firing
- by bleeeah
I have a simple web control (TaskList) that can have children (Task) which inherit from LinkButton, that can be added declaratively or programatically. This works ok, but I can't get the onclick event of a Task to be fired in my code behind. The code ..
[ToolboxData("<{0}:TaskList runat=\"server\"> </{0}:TaskList>")]
[ParseChildren(true)]
[PersistChildren(false)]
public class TaskList : System.Web.UI.Control
{
//[DefaultProperty("Text")]
public TaskList()
{}
private List<Task> _taskList = new List<Task>();
private string _taskHeading = "";
public string Heading
{
get
{
return this._taskHeading;
}
set
{
this._taskHeading = value;
}
}
[NotifyParentProperty(true)]
[PersistenceMode(PersistenceMode.InnerProperty)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public List<Task> Tasks
{
get
{
return this._taskList;
}
set
{
this._taskList = value;
}
}
protected override void CreateChildControls()
{
foreach (Task task in this._taskList)
this.Controls.Add(task);
base.CreateChildControls();
}
protected override void Render(HtmlTextWriter writer)
{
writer.Write("<h2>" + this._taskHeading + "</h2>");
writer.Write("<div class='tasks_container'>");
writer.Write("<div class='tasks_list'>");
writer.Write("<ul>");
foreach (Task task in this._taskList)
{
writer.Write("<li>");
task.RenderControl(writer);
writer.Write("</li>");
}
writer.Write("</ul>");
writer.Write("</div>");
writer.Write("</div>");
}
}
public class Task : LinkButton
{
private string _key = "";
public string Key
{
get
{
return this._key;
}
set
{
this._key = value;
}
}
}
Markup:
<rf:TaskList runat="server" ID="tskList" Heading="Tasks">
<Tasks>
<rf:Task Key="ba" ID="L1" Text="Helllo" OnClick="task1_Click" runat="server" />
</Tasks>
</rf:TaskList>
The Onclick event task1_Click never fires when clicked (although a postback occurs).
