I've searched the site and I cannot find a solution for my problem, so apologies if it's already been answered (I'm sure someone must have asked this before).
I have written a jQuery Popup window that I've packaged up as a WebControl and IScriptControl. The last step is to be able to write the markup within the tags of my control. I've used the InnerProperty attribute a few times, but only for including lists of strongly typed classes.
Here's my property on the WebControl:
[PersistenceMode(PersistenceMode.InnerProperty)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public something??? Content
{
get
{
if (_content == null)
{
_content = new something???();
}
return _content;
}
}
private something??? _content;
Here's the HTML Markup of what I'm after:
<ctr:WebPopup runat="server" ID="win_Test" Hidden="false" Width="100px" Height="100px"
Modal="true" WindowCaption="Test Window" CssClass="window">
<Content>
<div style="display:none;">
<asp:Button runat="server" ID="Button1" OnClick="Button1_Click" />
</div>
<%--Etc--%>
<%--Etc--%>
</Content>
</ctr:WebPopup>
Unfortunately I don't know what type my Content property should be. I basically need to replicate the UpdatePanel's ContentTemplate.
EDIT: So the following allows a Template container to be automatically created, but no controls show up, what's wrong with what I'm doing?
[PersistenceMode(PersistenceMode.InnerProperty)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public ITemplate Content
{
get
{
return _content;
}
set
{
_content = value;
}
}
private ITemplate _content;
EDIT2: Overriding the CreateChildControls allows the controls within the ITemplate to be rendered:
protected override void CreateChildControls()
{
if (this.Content != null)
{
this.Controls.Clear();
this.Content.InstantiateIn(this);
}
base.CreateChildControls();
}
Unfortunately I cannot now access the controls within the ITemplate from the codebehind file on the file. I.e. if I put a button within my
mark as so:
<ctr:WebPopup runat="server" ID="win_StatusFilter">
<Content>
<asp:Button runat="server" ID="btn_Test" Text="Cannot access this from code behind?" />
</Content>
</ctr:WebPopup>
I then cannot access btn_Test from the code behind:
protected void Page_Load(object sender, EventArgs e)
{
btn_Test.Text = "btn_Test is not present in Intellisense and
is not accessible to the page. It does, however, render correctly.";
}
