Forms Data Controls :: Entity Datasource And Query Extender Using LISTVIEW

Mar 9, 2011

I have a user control, named productslist.ascx. On pruductslist.ascx, I am using Entity Datasource and a QUERY EXTENDER and LISTview. I have a page Defualt.aspx. On Defualt.aspx, I have a TEXTBOX with a SUBMIT button for searching the site. Everthing works fine so far, AS LONG as the results of the Search is posted back to Default.aspx. What I want is for the results of the search to be posted on a different page.
So I created a new page, Results.aspx and set the postback url to it.

What I want is that when a user clicks the Submit button, after entering a search string, the text the entered is used to execute the query on Productslist.ascx and the results displayed on RESULTS.ASPX. Again, everything works fine as long as the results are posted on same page hosting the usercontrol, BUT I want the postback url to be a different page. I am coding in VB and VS 2010.

DataSource Controls :: Accessing FK From A Query Via Entity Query

Jan 21, 2010

I've got a query such as

Dim MediaQuery =
From m
In dB.DOWNLOADS _Where m.ID = id _Select

which returns a record from the database. One of the fields in the record is a FK to another table. I need to read this value to be able to set a dropdown based on the ID but I can't work out how to access it. For a standard record I can just do the following txtTitle.Text = MediaQuery.FirstOrDefault().TITLE

However with the foreign key it doesn't work like that. I've tried drpGroup.SelectedIndex = MediaQuery.FirstOrDefault().DOWNLOAD_GROUPS.ID where DOWNLOAD_GROUPS is the FK field but it returns Object reference not set to an instance of an object. If you're simply wanting to read some values from a single db record in the entitiy framework and one is a foreign key how should I go about getting the value?

Sequence contains no elements

Line 90: // find is user has already tracked this thread.
Line 91: var query = context.TrackLists.First(t => t.ThreadID == threadid);

Forms Data Controls :: ListView Not Returning Data But Query In Access Works

Mar 8, 2011

I have a search box on a web application that is to use a query I have built in Access to search through projects to find any that are related to the text entered in the search box.

The query in Access is just made up of parameters that use wildcards to search through all the fields. In Access the query works fine and returns the correct data but when I try and link this all up to a ListView in Visual Studio, the ListView just diplays the message "No data was returned"

Below is my page-behind code, hopefully you can see why it is not working but it looks like it should work to me.

I'm working on a job seeking website where the job seeker can search for a job , the search box is located in the master page, that's why i passed the keywords as a query string, and then the matching jobs will be displayed in a listview.

the keywords will be taken from two controls: a drop down list which the user can choose the location of the job, and a text box where he can type a keyword.

the select command of the sqlDataSource of the data list is as the following:

Forms Data Controls :: Using A Nested Listview To Display A Seperate Grid For Each Group Of Data Returned From Db Query

Jan 13, 2011

I am using a nested listview to display a seperate grid for each group of data returned from my db query. To get this working, I have adapted a piece of code to group the data prior to it being bound:

[Code]....

I am then using the following html markup:

[Code]....

[Code]....

This works as I want it to however some of the fields within the nested table need to be formatted as currency so I am trying to use Eval and {0:c} to do this however the moment I use Eval, the data items cannot be found

DataBinding: 'System.Data.DataRow' does not contain a property with the name '0'.

Forms Data Controls :: Gridview With Entity Frame Work Datasource?

Forms Data Controls :: Delete Row From ListView With No DataSource?

Apr 28, 2010

First time using a ListView control, I have it inside an UpdatePanel:

[Code]....

[Code]....

[Code]....

[Code]....

When the UpdatePanel Loads, it feeds the data to the ListView. Whenever the user clicks on a row in the ListView, a new window displaying a "note" pops up, the ItemDataBound event ties it all together. What I'm trying to do is add a button to each row so that the user can delete the row. This would call a Sql statement and then the row should disappear. I followed a couple of articles I found on ListView on how to do this, so I added a button called imgBtnDeleteNote (see markup above) and set the CommandName = "Delete", hoping that it would trigger the ItemCommand and ItemDeleting event (I have some bogus code in them, first I wanted to see if they would trigger).

The problem is that they don't seem to get triggered when I click on the delete button. All the rows in the listview disappear, and when I manually refresh the page they come back. My guess is that the events are not firing because I'm not using a DataSource object in the aspx code, but I'm not sure.

Forms Data Controls :: ListView With Datasource And Later Adding Items Dynamically?

Dec 11, 2010

I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.

Forms Data Controls :: Listview Sort - No Datasource Assigned - OnSorting Logic?

Jun 22, 2010

I have a listivew that is assigned a datasource in the code behind based on query string options. From what i have found out, once there is no datasource assigned in listview html then the sort feature stops working automatically and you must put the code in the _Sorting event. I cannot find a good example of this logic.

I am using entity framework. My model has entity tblGameInfo where in navigation properties are associations called tblPlayer1 and tblPlayer2 which links to entity tblPlayer. I have listview on my page where I want to show game info with players names. I have found that in of listview I should have e.g. one of those:

But it does not work. I got nothing displayed in a listview. I have tried many different options but cannot find working one. Probably is some simple mistake but I am new to asp.net and cannot find it. Second problem with this is editing. In edit template there is dropdownlist with all players.

[Code]....

How do I databind it? It is not allowed to bind and change properties? It writes me that element does not exist on a list of elements.
