Hello to all the smart people,

I'm trying to create a composite control which include nested controls from the great Ajax Dev.

I overcame a lot of issues and can be helpful in some but my latest problem doesn't seem to disappeared.

when i declare a trigger in the code page of the composite control i get this error message:

"The ControlID property of the trigger must reference a valid control"

even thoughi placed everything correctly (at least in my understanding).

the code is as followed:

[DefaultProperty("Text")]

[ToolboxData("<{0}:SingleRecControl runat=server></{0}:SingleRecControl>")]

[AspNetHostingPermission(SecurityAction.Demand, Level = AspNetHostingPermissionLevel.Minimal),

AspNetHostingPermission(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]

public class SingleRecControl : CompositeControl

{

private ScriptManager sm = new ScriptManager();

UpdateProgress progBar = new UpdateProgress();

UpdatePanel ratePanel = new UpdatePanel();

ControlValueTrigger trig = new ControlValueTrigger();

public Label ItemName = new Label();

private Style[] objStyle = new Style[3];

protected override void CreateChildControls()

{

base.CreateChildControls();

Controls.Clear();

sm.EnablePartialRendering = false;

sm.EnableViewState = true;

sm.AppRelativeTemplateSourceDirectory = "~/Default.aspx";

sm.ID = "cc2";

sm.EnablePartialRendering = true;

//Controls.Add(sm);

btn.Visible = false;

btn.CommandName = "NEXT";

btn.ID = "Test";

btn.UseSubmitBehavior = false;

btn.Text = "Test";

//_container = new CompositionUpdatePanel(this);

//_container.ID = "Container";

//_container.Mode = UpdatePanelMode.Conditional;

//Controls.Add(_container);

objStyle[0] = new Style();

ItemName = new Label();

ItemName.BorderStyle = objStyle[0].BorderStyle;

ItemName.BorderWidth = objStyle[0].BorderWidth;

ItemName.BorderColor = objStyle[0].BorderColor;

ItemName.Width = objStyle[0].Width;

ItemName.Height = objStyle[0].Height;

ItemName.ID = "lblCheck";

ItemName.Text = "bl";

ItemName.Visible = true;

this.Controls.Add(ItemName);

progBar.ProgressTemplate = new BarGif("blablablablablabla");

progBar.ID = "GifBar";

ratePanel.ContentTemplate = new RemTemp();

ratePanel.ID = "RatePanel";

trig.ControlID = this.ID + "_" + ItemName.ID;

trig.PropertyName = "Text";

this.ratePanel.Triggers.Add(trig);

this.Controls.Add(sm);

this.Controls.Add(progBar);

this.Controls.Add(ratePanel);

}

protected override void Render(HtmlTextWriter writer)

{

base.Render(writer);

this.Controls.Clear();

sm.RenderControl(writer);

progBar.RenderControl(writer);

ratePanel.RenderControl(writer);

ItemName.RenderControl(writer);

}

can someone please help me?

I can't trigger the ITemplate that i declared (maybe improperly?) to show first a gif on the progress and afterwords the calculated information from the database.

here are the templates:

public class BarGif : TemplateControl, ITemplate

{

private string _barPic;

public BarGif(string template)

{

this._barPic = template;

}

public void InstantiateIn(Control container)

{

LiteralControl lc = new LiteralControl("<img src=&quat;"+this._barPic+"&quat;/>");

container.Controls.Add(lc);

}}

public class RemTemp : SingleRecControl, ITemplate

{

public event System.EventHandler ProssFinished;

private SophiaClass.DemoDbAcc dbAcc=new DemoDbAcc();

private DataTable itemRateTable=new DataTable();

public string userNam = "31";

public RemTemp()

{

RecomTableBuilder();

}

protected void RecomTableBuilder()

{

dbAcc = new DemoDbAcc();

itemRateTable = dbAcc.GetRateTable(int.Parse(userNam));

if (!this.DesignMode) Thread.Sleep(4000);

ItemName.Text = recItem.ItemName;

ItemDesc.Text = recItem.ItemDescript;

ItemPhoto.ImageUrl = recItem.ItemPhotoPath;

}

private Items MakeArrRec(DataTable table, int index)

{

recItem = new Items();

recItem.ItemID = table.Rows[index]["id"].ToString();

recItem.ItemName = table.Rows[index]["itemname"].ToString();

recItem.ItemDescript = table.Rows[index]["itemDesc"].ToString();

recItem.ItemPhotoPath = table.Rows[index]["itemPhotoPath"].ToString();

return recItem;

}

}}

please advise.......

i feel so lucky to have someone to share my troubles :-)
