How to share data between two controls

[Guest]

Hi!



I have a big big problem!!!





what I will do:



on my web form: UpdateFacility.aspx



are two controls: SearchFacility.ascx and AddEditFacility.ascx



SearchFacility has a dropdown list. when the user choose an item from the
dropdown list the SearchFacility should transfer the selected item value to
a text box on the second control (AddEditFacility).



I try it so:



I set:

ViewState.Add("currentFacilityOID", _ddlFacilities.SelectedItem.Value);



On the InitializeComponent() in AddEditFacility is
ViewState["currentFacilityOID"] ever null.

It seems that on this web form are 3 different ViewStates:



1. ViewState on the UpdateFacility.aspx

2. ViewState on the SearchFacility.ascx

3. ViewState on the AddEditFacility.ascx´



But why?



One possibility that I see is to make this:

Application.Add("currentFacilityOID", _ddlFacilities.SelectedItem.Value);

But I don't want to use the Application object.





Exists any possibility to share data between two controls on the same web
form????

What about adding a hidden element to the form and using
it to share the info?

Just make an <INPUT TYPE=HIDDEN ID="someID"></INPUT>.

On the postback, you can refer to it with Request.Form
["someID"] to get the value.

All you need to do is handle the SelectedIndexChanged event of the
SearchFacility dropdown and in the handler set the edit box value.
EditBox.Text = DropList.SelectedValue.
