Forms Data Controls :: Create List View To Provide Functionality
Apr 26, 2010
I am trying to create a list view to provide functionality similiar to the pages in this article(will end up being much simpler in my case)
[URL]
Basically I need three columns. Column 1 will be populated on page load with a list of user names and some data. Clicking on a user from column 1 will query for data regarding that user and bring back multiple rows to be displayed in Column 2. Clicking on data from a row in column 2 will return rows to be displayed in column 3. I am just curious as to how some of you guys would approach this. Ive looked at grouping templates and some articles regarding listviews with multiple rows but. Would it be easier to use 3 seperate listviews? Any ideas or articles to point me in the right direction?

I am an ASP newbie and I am trying to create a listview with rows and columns that are the same height on every page, rather than shifting when you click the Next button. Is there a style or something you use when you create the listview?

I am in need of getting the correct sysntax for being able to use paging with a datalist whose data is being generated by a SQL Datasource and a stored procedure inside the aspx(asp.net VB...Not C#) page. A Gridview or any other rigid control that does not allow full control and layout will not work so I have to use the datalist. I have the datalist working perfectly but I need to add paging. I did some searching and found a good solution. It was a C# solution, in particular the code behind syntax so I used a code converter to convert it to VB. However, as I am not an experienced coder I need help converting the portion for handling the datalist. I am fairly confident I have the buttons on the aspx page worked out. I will ask that if you se something I need to do besides the section(5) I have listed please offer suggestions. So that you can help me better I have boken the code out into sections where I'm listing the code I copied, my code and the section I need help with. I think at a minimum I will have to change the references of Repeater to Datalist.
The section I need help with is section 5 where the original autor is referencing items generated in the Repeater where he used XML. As I said I'm using a SQL Datasource with a Datalist so I truly don't understand what I need to change to get the code behind to work with my Datalist. As always I appreciate all of you guys and ladies help. And also as always I will ask to please provide the actual code to type in because telling me how to do it just won't help very much. Sorry about that.
Here is what I have:
SECTION 1 - The buttons to handle the paging
*******************************************
<td> <asp:label id="lblCurrentPage" runat="server"></asp:label></td>

<tr>
<td> <asp:button id="cmdPrev" runat="server" text=" << " onclick="cmdPrev_Click"></asp:button>

As I am new to listview i had a problem with it, I hav to sort the values in the list view, when we click on the header links, so i hav done it by
commandname="sort" and commandargument="My_table_column", and i hav suceeded doin it.
Now my problem is i hav to do some search by 6 conditons like
CustomerId,CustomerName,OrderNumber,OrderDate,OrderType
For this i am using row filter and filtering the values in the Dt and then i am binding the dt back to the ListView here i am getting the problem as "The data source does not support sorting". I am aware that i am changing the data source, but before binding the datasource manually to
dt,
i hav tried doing this to make the datasourceid null which i hav attached previously
lvSalesLayOut.DataSourceID = "";
But i am getting the error post me how to get this done programatically.

I have a form in which I have a dropdown list and a list box.
This dropdownlist is populated by a column in thetable . This drop down list may have values ranging from 1 to 5.
This values in the dropdownlist are to be made the caption headings of the list view control.
For insance if there are three values in the dropdown there should be three columns in the list box with the heading as the values of the dropdownlist.for 5 it should be 5.
Also there are two additional columns which would be constant.

I need to create a repeat region area where I display the Area as a heading and then listing the cities within that area.
I can achieve this using a gridview and nesting one inside another using this tutorial: [URL]
But I really need the ability to customize the page that only a Listview offers. So does anybody know of a good tutorial to do this?
Note I'm Using MS Access for the datasource of both City and Area tables.

I am trying to achieve a list view with this structure.I have many categories with many products
<table>
<tr>
<td colspan="3"><h2>Cat1</h2></td>[code]...
As you see the <td> for products must always be no more than 3 columns. but if there are 8 products then there will be 3 rows (2 full rows and one row with only 2 products) So far I have this:
<asp:ListView ID="lvProducts" runat="server">
<LayoutTemplate>
<table cellpadding="0" cellspacing="0" border="0" width="800"> [code]...
it doesn't work .

How would i create a details view that also contains a list?
My aim is to have a details view that displays information about a person and then have a list on the same page that displays facts about that person.
Currently, my details view is working fine. I just need to add the list part. The details view inherits Models.MyViewModel which is a custom class as the details come from multiple tables.
