Autopostback works but when one dropdownlist is selected the page refreshes. When the user select one dropdownlist, another dropdownlist will then populate if not its empty. After submitting the form, selecting dropdownlist will remove all the validation message. What i want to achieve is to have javascript to manually postback instead of using autopostback so that the validation message will still remain after selecting from dropdownlist but
View 1 RepliesI have an ASP.net web page with VB code behind linking to an MS SQL DB. On the web page I have 4 DropDownLists and 1 GridView. Each DDL is populated with a SELECT DISTINCT query on 4 corresponding columns from 1 table in the DB. What I would like to be able to do is: when any of the DDLs have their selected item changed the other DDLs are updated. Crude example:

I was having a heck of a time populating a gridview combo box.I learned a ton in the last 48 hours but would really like to know the answers to the bottom three questions.You guys are the experts, so I'm hoping you will enlighten meBut the summary of it is below:I was never able to get the ComboBox to bind to the data source. I tried everything until I turned blue. So I went to the basics and coded all the automatic stuff. I'm curious as to why the automatic binding didn't work. Perhaps its because my gridview datasource was LINQ.Here is how I pulled it off. I hope someone down the road benefits from the last 48 hours of my delima:First of all, know that I have two drop down lists on my form, one is the GPField and the other is the BankField. These are already populated DDLs that are static. So I used them to cheat on the values instead of using enums.
Sub fillGPFieldListDDL(ByVal obj As Object)
Dim db As New CompanyDataDataContext
Dim myConn As New Connection With {.ConnCls = ConnCls}

I'm looking for a solution to implement in web apps where I have the option to see a print preview or print either a gridview, datagrid, or datatable or export it to word or excel. What's the best method to do this or has someone written a class that does this, and does it well (I've seen many examples, but many still have errors)?

View 3 RepliesUsing DevExpress 10.2 within Visual Studio 2008 with VB.Net I have created a single gridcontrol that contains two different gridviews. The gridviews are related using an id column. Basically if there are related details about a row in the first gridview then the user can click on the plus sign to see all the related details. When I have any row on the first gridview I am able to get the focused row. Yet when I have the focus on any of the rows in the second gridview I am unable to get the focused row or the content of the row.

Is there any way to get the value in id from the focused inner gridview? Or at least figure out the parent row and grab the id value from there?
When I have changed the name of a table field name none of my combo boxes or grid views work properly. The TableAdapter still refers to the original name. Is there an easy way to make the change propergate through the program or do I have recreate all my TableAdapters.
View 5 RepliesI've created a Gridview control that pulls some data from my database, but doesn't display all of the information I'm hoping it gathers. I choose not to display the primary key for user interface purposes, but require that key for basic operations on the grid.I'm currently attempting to add a "Delete" option to the table, but unfortunately I'm having very little luck. Here's my .aspx file.
<asp:GridView ID="ManagerList_GV" runat="server"
AutoGenerateColumns="False" AllowSorting="True"
DataKeyNames = "ManagerID" OnRowEditing="editManager"

I am currently programming within Visual Studio 2010 using VB.Net and DevExpress V10.2 Winforms. I currently have a DevExpress GridControl that contains two DevExpress GridViews.So there is the main view and the subgrid (similar to the DevExpress demo for Master-Detail Grids - example with WinForms and better view with ASPxGridView). Currently the data for the grid is fetched into a DataSet:
If myDataSet.Tables.Count > 0 Then
myDataSet.Relations.Add("Details", myDataSet.Tables(0).Columns("id"), myDataSet.Tables(1).Columns("id"))
