View 2 RepliesI have a drop-down list that is wired up to a datasource from one table to retrieve a Vendor ID and Vendor Name. This ddl is outside a FormView that is wired up to a datasource containing Vendor contracts.
When I choose a Vendor from the ddl, I am able to populate a textbox outside of FormView with the Vendor ID from the ddl. However, what I need to do is populate a textbox within FormView with the Vendor ID. FormView is in Insert Mode by default since my page will be used for Adding Contracts only.

What I have is a text box that has a max length of 2. Is there a security reason to add a validator to the textbox. I should add this is in Asp.net.

When the user navigates to a new page, this ddl's selected index is determined by a cookie, but if the ddl doesn't contain that cookie's value, then I'd like it to be set the 0. What method would I use for the ddl? Is a loop the best way, or is there a simply if statement I can perform?
This is what I've attempted, but it doesn't return a bool.
if ( !ddlCustomerNumber.Items.FindByText( GetCustomerNumberCookie().ToString() ) )
ddlCustomerNumber.SelectedIndex = 0;

I have a page that has two drop down lists on it and a button. All controls sit in an update panel. The first drop down list (ddl1) contains a lot of values which caused a huge viewstate so I disabled viewstate on it. In the page oninit event I populate the drop down list every time the page is posted back. This all seems to work fine, it shows all the values and I can access the selected value in my event handler.
ddl1 has the autopostback attribute set to true so when its value changes the second drop down list (ddl2) is populated with some values that depend on the selection in ddl1. This also works fine, the values in ddl2 change when I select a value in ddl1.
ddl2 does not have viewstate disabled. The button that sits under my two drop down lists is disabled by default and becomes enabled when the value of ddl2 is changed to anything except string.empty. This is where I run into problems. ddl2 does an autopostback too but it seems to lose the selected index/value. When I'm in my code to check whether to enable or disable the button the selected index is always 0 and the selected value is string.Empty.
If I enable viewstate on ddl1 this all works fine. Could anyone point me to what I'm doing wrong?
Here is the code executed by the ddl2 postback:
