Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.
I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
In my application I have panel which has 5 textboxes. I've written several functions for checking each of textbox if the entered value is ok (number, is this number in database, etc.). If error occurrs textbox which caused it has different color of background.
However I wanted to write (add) function which will check if one of the textboxes has the same value as other. The problem is that function is checking blank textboxes, although it shouldn't - I wrote if statement which allows checking only non-blank textboxes but it doesn't work.

I am having datagrid in that I have one column that should have table. Now I want to know that how can I include table in datagrid. My table values may differ from each rows in datagrid. So that also should be accomplished.
I have a usercontrol with a datagrid that is used throughout my web application. The datasource is passed in a public method from the master page to this usercontrol, as the data selection is different on each page where this usercontrol is used.But by doing this, I'm having a problem with paging, as the datasource is lost after postback. I can't do the data selection in the usercontrol itself as the dataset is passed as a parameter.
I have visual 2010 with net 3.5 web app. I was implementing EntityFramework in my project and added a gridview to a entity source control. It worked ok, with select, update, and delete buttons enabled on the grid. But then, i needed to add a template field bound to a Foreign table, so my users select value from a list instead of writing the code. After that, my app fires error when i delete. I tried everything, inclue dakeyNames, write code on my RowDeleting, RowDeleted, RowCommand, but error persists.
Now, i can delete the row, but it then i get the error Object reference not set to an instance of an object If i implemente delete code on RowCommand i get the error: Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.

(like an AJAX accordion). this website for example ( ignore the language, couldnt find any better example [URL] Now, i've been told that this works by using "Dynamic Div Creation" which i have no idea how it should work this way. Is it possible to make it work by using an Accordion inside a datagrid? or what?

i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource(); sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString(); sq.SelectCommandType = SqlDataSourceCommandType.Text; sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1"; string result = sq.Select(some overload that's stopping me);
