Asp net dropdownlist selected value not updating

How does the updated read the dropdownlist to know what is selected?

This link is the kind of issue i am having - but in and cant get it to work, i think from reading it, i need to set the value of the parameter to the selected value of the dropdownlist - not sure though.

Here is the code for reference: Hi, Selected Value property of the Dropdownlist is to make one of the existing items in the dropdownlist as default selected value.

But in your case, you could never find "Dsr Number" as an existing item in the dropdownlist as you were binding "Full Name" as items for the dropdownlist. Sometimes there is information in the node I am editing.

Remove the Selected Value property for the dropdown list in the Edit Item Template and it will work. If I need to edit a node that does have the Dsr Number, First, Last fields then it will pre-select the person who is tied to that account, works like a charm. Is Empty Or Null(str Param)) If you were using stored procedure, you need to pass null or empty string accordingly.

Its when it can't find the First and Last fields that it errors out on me, like a node with no information in the other fields yet. Hi You need to check for the null values when updating. Thanks Alright, So I need to add a command to fire when changing to the updating state that checks if the value is null?

Every node is tied to a Sales Person in a different table via their identification number.

Since I already have the database populated with the data I want to use I won't need to do any inserting, only updating.

Also, I'm still not sure why you're checking for the selected value since the list will have no selection when the grid is bound. Let me explain and you can tell me if I'm just doing it backwards. The Select contains a Button "Dag Details", which is displayed as a Viewer Frame in Autodesk Map Guide.

Remove the Selected Value property for the dropdown list in the Edit Item Template and it will work.

Did you not notice that Dsr Number was his Data Value Field?

Everything works great when binding the data to the Drop Down List but when I try to edit an item which tries to pass a null value to the Drop Down List (no Dsr Number tied to the field) I get this Error: I know why its happening, I just don't know how to fix it. I am still using the Sql Data Source instead of a Object Data Source because I am still learning about code-behind, BLL etc.

So I have to go with what works until I have time to learn more.
