View 2 RepliesDynamic DataGrid - Dynamically "transform" DataGrid To Display The Selected Search Template
May 23, 2011I have a search form on that will be pulling search template queries from a table in the underlying (an Access db on a share). The search form has a calendar control for filtering by date range, a listbox containing the names of the search templates, a second listbox which lists the fields in the selected template, and then some controls which show/hide themselves depending on which field is selected so that the user can pick a field and enter it's unique criteria in the appropriate control for filtering. Below these controls is a DataGrid, which will obviously display the results.
The problem is how to dynamically "transform" this DataGrid to display the selected search template. These templates do not represent tables in the underlying; rather they represent preconstructed SQL queries (stored in a table) which are essentially SELECT queries with joins and no WHERE clause (so they are the results of multiple tables joined together by their keys).
To be honest, I'm having trouble even generating the LINQ queries to represent these template dynamically, but that's not as important, since I can manually translate the SQL queries into LINQ. This is definitely not the preferred method, as the whole point of putting these templates in a table, rather than code, was to allow for future additions without rebuilding/redistributing the application interface.
Asp.net - Get The Selected Value Field Of Listbox?
Feb 9, 2012I have Listbox, that I want to assign primary key, and a text (eg. students table). So i wrote this code.
mySQLCmd.CommandText = "SELECT studentname, studentid FROM studentstable WHERE Year(DOB) = " + selectedYear
Dim dt As New DataTable
myReader = myCmd.ExecuteReader()
[code]....
When I select something on the listbox, both of selecteditem and selectedvalue properties just return the student name, not the student id. So I get this error.
Error on Line2. Conversion from string "RichardCole" to type 'Integer' is not valid.I don't know why? So i do i get the studentid value back ? I need to know the ID coz name can't use as PK so.

Asp.net - Bind A Text Box To A Field Selected By SQLDataSource ?
Feb 8, 2011I'm looking for the easiest way to bind data from a SqlDataSource to textboxes dropped in Visual Studio 2008.For example, I have 4 textboxes currently that have Address, City, State, Zip.I also have a SqlDataSource on the page fetching the ID of the record and selecting those 4 fields based on ID. How am I able to quickly bind each box to those particular fields selected? I would think this would be really straight forward - but seems it's not. Seems like the answer is funneled towards having to create a GridView or some type of control.
