[Code]....
[Code]....

No data is loaded when the button (btnSearchWrd) is clicked. Instead, in the Firefox Error console, it listed these two errors:Error: item is undefinedError: ys.WebForms.PageRequestManagerServerErrorException: Could not determine a MetaTable. A MetaTable could not be determined for the data source '' and one could not be inferred from the request URL. Make sure that the table is mapped to the dats source or that the data source is configured with a valid context type and table name, or that the request is part of a registered DynamicDataRoute.

Forms Data Controls :: Populate Dropdownlists Within A Listview?

Jul 28, 2010

I'm comfortable populating dropdownlists in a standard webform, but I seem to be having trouble populating them from within a gridview or listview.I know that I'll probably need to use the find control method, I've had a stab at it with the following:

[Code]....

The purpose of this is to allow someone to look at a bunch of records, and in a dropdownlist add an item to a group, but this "group" is in a separate table, so I want to take whatever value that select in the dropdown menu, lookup their user id, and add both bits of information to the other table, so it's technically not even editing, even though i suspect I'll need to use the edititem template?

Oct 10, 2010

I'm currently developing an ASP.net application w/ VB as the code behind. I have a page that shows all the user name currently assigned to the system. The problem now is that the page does not communicate directly to the database. Instead, I use HTTPrequest to get all the user names from a different sever. Now I want to populate the listview control w/ the response that I got (and not directly from the database).

Data Controls :: Populate ListView With DataTable

Nov 22, 2015

This is what i want to do with my website. I want to pull data from an access query and and load it into a listview table. The user will sort through the data on the website and remove the rows she doesn't want. After the user is done, they will click a send button that will email the data to the appropriate party.I have read the access query data into a data table. I have the list view table built, but I am unsure how bind the data table into the listview table. Is this the best route to go? Will binding the datatable to the listview table allow the user to delete rows out of the datatable?

Protected Sub btnView_Click(sender As Object, e As System.EventArgs) Handles btnView.Click
Dim query As New QueryBuilder.SelectQuery("qryVendorReport")
'Fill data table with vendor information
Dim sample As String = ""
Dim results As New DataTable
results = (db.fillTable(query.toSelectQuery))

[code]...

how to bind the results datatable to lvdatasource. I tried a few different ways to do this with no luck. Maybe the syntax I trying to use is incorrect.

Forms Data Controls :: Showing Linq Result Values Inside Dropdownlist Inside Listview

Jun 22, 2010

I have a listview that is showing its result by using a linq query. The linq query goes like this.

[Code]....

* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.

[Code]....

And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):

[Code]....

I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these

DataSource Controls :: LINQ Load Collection To Populate Dropdownlist?

Apr 5, 2010

I have a partial class extending my Entity Model. I'd like to write a method that returns a collection of types from my entity framework model. For example, I'd like to get all the states to populate a drop down list. So I've written a method called getallstates(), similar to the example below:

[Code]....

I tried returning a list of Objects, and a list of states to my calling method to be used to bind to a drop down list. However I get an error that:

Server Error in Application. Unable to cast object of type 'System.Data.Objects.ObjectQuery to type 'System.Collections.Generic.List`1[System.Object]'.

What should my return type be for this function?

Forms Data Controls :: How To Push Down Outer ListView From Nested ListView Control

Mar 13, 2011

I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
