DataList ItemCommand using Placeholder Ctrl

[Stuart Shay]

Hello All:

I have a Datalist where each row has TextBoxes and Dropdowns that are
created dynamically. The code renders correctly and is very similar to this
sample I found

http://www.codeguru.com/csharp/.net/net_asp/controls/article.php/c12495/

void rptFields_ItemD ataBound(object sender, RepeaterItemEve ntArgs e)
{
if (e.Item.ItemTyp e != ListItemType.It em && e.Item.ItemType
!= ListItemType.Al ternatingItem)
return;

DataRow dr = ((DataRowView)e .Item.DataItem) .Row;
PlaceHolder pl = (PlaceHolder)e. Item.FindContro l("plControl" );
switch (dr["DataType"].ToString().ToL ower())
{
case "string":
TextBox txt = new TextBox();
txt.ID = "txtField" + dr["pkParamete rID"].ToString();
pl.Controls.Add (txt);
break;

case "tf":
CheckBox chk = new CheckBox();
chk.ID = "chkField" + dr["pkParamete rID"].ToString();
pl.Controls.Add (chk);
break;
}


When I call the DataList ItemCommand Event, I am unable to reference the
dropdown list or textbox by using the FindControl Method even if I hardcode
the ControlId as a test.

How can I get the selected value or text of the control

Any help appreciated

Thanks
Stuart

Re: DataList ItemCommand using Placeholder Ctrl

You are referring to ItemCommand event. Note, that DataItem is available
only in ItemDataBound event. This is the only point where the control meets
its datasource.
