radiometric dating for kids - Gridview templatefield not updating
I have converted the label into a templatefield and added a dropdownlist which is getting polulated in the Rowdatabound event. User Control Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load Dim i As Integer = 0 Dim str Time List, str Time As String For i = 0 To 23 str Time List = "" str Time = "" If Len(i) = 1 Then str Time = "0" & i & ":00" If Len(i) 1 Then str Time = i & ":45" str Time List = str Time List & str Time DDLST. Add(str Time List) Next str Time List = str Time List & "" End Sub Public Property Selected Value() As String Get Return DDLST.
When I test the update i get an error so I am ussuming its still trying to update from the label rather than using the dropdownlist. here is my code: Protected Sub Grid View5_Row Data Bound(By Val sender As Object, By Val e As Grid View Row Event Args) Handles Grid View5. Edit Then Dim ddlst As Drop Down List = Direct Cast(e. Find Control("DDLGVST"), Drop Down List) Dim i As Integer = 0 For i = 0 To 23 str Time List = "" str Time = "" If Len(i) = 1 Then str Time = "0" & i & ":00" If Len(i) " Delete Command="Delete Event Date" Delete Command Type="Stored Procedure" Select Command="Get Event Dates" Select Command Type="Stored Procedure" Update Command="Update Event Dates" Update Command Type="Stored Procedure"Partial Class controls_time List Inherits System. Selected Value End Get Set(By Val value As String) DDLST.
This functionality enables the Grid View control to provide built-in, bi-directional sorting.

After you've finished this article, read Improving the Sort Arrows Grid View Control, which discusses the enhancements in more detail. NET version 2.0 was released, I wrote a book and dozens of articles on the Data Grid control, which was the most functional data Web control in the ASP. The Grid View can be bound to data source controls like the Sql Data Source and Object Data Source, and paging, sorting, editing, and deleting can be implemented without having to write a single line of code.
This was accomplished by programmatically looping through the Data Grid's I recently needed to implement this functionality in a Grid View control. NET page, like I did with the Data Grid demo, I decided to instead create a custom Web server control that extended the Grid View control, adding the necessary functionality. If the Grid View is bound to a data source control that supports sorting, the Grid View will internally re-bind to the data source using the new sort order.
In this article we will look at the steps for building such a custom control as well as how to use the control in an ASP. The custom control's complete source code and a demo application are available for download at the end of this article. If you have programmatically bound data to the Grid View, then you will need to create an event handler for the property is toggled.
event is raised when a row's Update button is clicked, but before the Grid View control updates the row.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
From my posts I'm sure you can see I'm spending too much time trying to fathom the mysteries of binding to Sql Data Source and not enough time producing results, probably should have stuck with the old style of coding a dataset/dataadapter solution as in ASP.

I have a gridview with an update capabilities - a textbox column (room Name), a dropdownlist(org ID), a dropdownlist(room Type ID),a checkbox column (dial Out), a checkbox column (dial In).
IF you have enabled editing and, like we see, do have an Edit Item Template, then mostly likely you have a single row in edit mode - and a single row to update.
Im using a LINQData Source to populate a Grid View of Universities.
When I click the update link the Gridview returns to display mode with no errors but the data from bound text fields or dropdown list isn't updated in the table.
