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_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType != ListItemType.Item && e.Item.ItemType
!= ListItemType.AlternatingItem)
return;

DataRow dr = ((DataRowView)e.Item.DataItem).Row;
PlaceHolder pl = (PlaceHolder)e.Item.FindControl("plControl");
switch (dr["DataType"].ToString().ToLower())
{
case "string":
TextBox txt = new TextBox();
txt.ID = "txtField" + dr["pkParameterID"].ToString();
pl.Controls.Add(txt);
break;

case "tf":
CheckBox chk = new CheckBox();
chk.ID = "chkField" + dr["pkParameterID"].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

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.
