usercontrol initialization question

[Florian Paulus]

hallo group!

i have a user control that using a listbox and a dataset to fill it.

usually i can give some parameters in the form of public properties to
user controls for example :

<my:MinMaxAlpha Field Required="false " ID="cfCity" Label="City:"
MaxCharacters=" 50" MinCharacters=" 3" runat="server"/>

so here im setting the label text and it works fine.

now for the usercontrol that has the listbox i want to pass the dataset.

unfortunately i seem to be able to just pass strings there so my
question is, how can i pass a dataset from outside?

the dataset itself is the result of a methodcall.

the page containing all this is using a wizard control and the data
depends on a wizard step before, so i tried to pass the dataset in the
wizardstep event, but this assignment seems to be done after the control
is rendered, cause if i set a breakpoint in the control's page_load
event where the dataset is assigned to the listbox its still null.

how can i accomplish my mission? i hope its understandable.

cheers

RE: usercontrol initialization question

Good evening,

1. Programatic data binding:
Add new property called i.e. MyListDataSourc e and a method:

public object MyListDataSourc e
{
get
{
return myListBox.DataS ource;
}
set
{
myListBox.DataS ource = value;
}
}

public void MyListDataBind( )
{
myListBox.DataB ind();
}

finally, in code behind of the page you placed your control:

cfCity.DataSour ce = myDataSet;
cfCity.DataBind ();

2. Declarative data binding.
If you are planning to use any of the data source control (SqlDataSource,
ObjectDataSourc e, etc) add one additional property:

public string MyListDataSourc eID
{
get
{
return myListBox.DataS ourceID;
}
set
{
myListBox.DataS ourceID = value;
}
}

<my:MinMaxAlpha Field Required="false " ID="cfCity" Label="City:"
MaxCharacters=" 50" MinCharacters=" 3" runat="server"
MyListDataSourc eID="mySqlDataS ource" />

I would implement both options to give user control users a choice.

Hope this helps
