Detailsview dropdownlist not updating


The Edit Item Template is used to display user interface while Details View control is in edit mode. We use Bind() to display data and this data can take part in Insert and Update operations.Similarly, the Insert Item Template is used to display user interface while Details View control is in insert mode. When we use Bind() method in a Template Field, the Bind() method supports two-way data binding, which means data can be updated, inserted, and deleted automatically from the data source control.If it is in the Details View1_Mode Changing method, the mode has not actually changed yet.EDIT: Also, make sure you set up the Data Text Field and Data Value Field like so: Also remove the Selected Value bind; it does nothing except throw errors. Data Bind() End Sub Protected Sub Details View1_Data Bound(sender As Object, e As Event Args) Dim lbl Comp As Label = Details View1. Bind the drop downs in the Page_Load event when the state is NOT Page. View state will manage the state for each post back so you do not need to rebind the drop downs. I implemented what I think you said and the results were/are the same; initial display of the record in the update page shows the correct rank in the correct table drop down. Find Control("lbl Cmpt") Dim hdn Rnk As Hidden Field = Details View1.

Find Control("lbl Cmpt") Dim lbl Rnk As Label = Details View1. Find Control("lbl Rank") Dim lbl HRnk As Label = Details View1. Data Source ID = "Sql Data Source4" End If ddl Rnk. I know that knowledge of View State is one among many deficiencies in my programming expertise. What I think you said: Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load If Not Is Post Back Then Dim lbl Comp As Label = Details View1. Data Source ID = "Sql Data Source4" End If ddl Rnk. Find Control("hdn HRank") Dim ddl Rnk As Drop Down List = Details View1. Find Control("lbl Cmpt") Dim lbl Rnk As Label = Details View1. Updating the record with different ranks for Rank and Highest Rank shows the correct tables in both drop downs but the Rank and Highest Rank are Null in both debug and SQL Management Studio 2008 R2. Find Control("hdn Rank") Dim hdn HRnk As Hidden Field = Details View1. Item Updating Dim lbl Comp As Label = Details View1. Data Source ID = "Sql Data Source4" End If 'lbl Rnk.

Data Bind() End Sub Protected Sub Details View1_Item Updating(sender As Object, By Val e As Details View Update Event Args) Handles Details View1.

This is the same issue but on changing or updating the data. Find Control("ddl Rank") Dim ddl HRnk As Drop Down List = Details View1.
