Forms Data Controls :: ListView Control Does Not Render First Row Of Data In Database Column
Aug 5, 2010
using .NET 4, SQL 2008 R2 and VS2010:
My issue is that the first row of data in my db table does not seem to be output to my ListView control when I run the page. The first item in the ListView control is the 2nd row of my db table.
If I execute the stored proc listed below in SQL Server Mgmt Studio all rows are returned to the query results window.
How can I make the column of ListView Control invisible. The last column's header I have put in a label control and its item are in a html img control .
My problem is this source, never render form tag in first row. It works fine. Firefox, Chrome, IE6, IE7 displays fine but IE8 overflows first row. When i set form tag style display:none other rows does not show cart image but first row still shows.
using asp.net 4 and vs 2010 I have a listview that displays data from a database. I have to configure it to display all column data where present, however, not all columns have data, with the result that blank spaces get rendered where this data would normally be displayed.
The code:
[Code]....
So, for example, some of the individuals that exist in this table might no longer be associated with a specific department, institution or have data in the "Address2" column.
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).
I want to name the headers of the ListView control acording to values of the first rows of a table in the database. This I want to do because the number of columns varies for each cutstomer and also the name of the column.
I'm really new at asp.net 3.5 I'm comming from Classic ASP and I have been experimenting with ASP.NET. I'm trying to use the ListView Control to display a products catalog comming from a database. My first test was succesfull but I have a question.I want to be able to display the title of the product in Bold if certain conditions exists for that product. I tried using the ItemDataBound event but I don't know how I to get the value from the database field.I have the following code
ASPX PAGE

CODE BEHIND
Protected Sub productsList_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) Handles productsList.ItemDataBound
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?
I have read all kinds of great things about the new List View (well it was new when 3.5 was introduced). But I have not figured out how to set the width of a column. I have tried setting width in Layout, Item, Alternate, but none seems to affect the width.In related question, is there any way to hide a column?
I'm using following code to reorder listview columns programatically somehow it is showing incorrect behaviuor for certain scenarios. Please let me know if there is any alternative way -

what I have to add/subtract from the following listview to change the table and column width. All my attemps like the style="width: 50%" have no effect.
Now, what i want is that , when a user select something from any dropdownlist , a fuction should be called in which I can get column and row of that dropdownlist.
I can get the dropdownlist's id in that function along with row and column of dropdownlist.

I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users. They should be able to just click on the checkbox so they value in the database column gets changed as well (as I want to run update queries behind it), but not passing via the command column 'EDIT'.=> problem I'm having now is that the bit column in the database doesn't get updated.
My plain texts are image links and pdf URLs from a database table, in groups, in the correct order but I'm not sure how to render them correctly (sample image below shows what I am trying to render)
Is there any way to make a repeater template intelligent enough to render an "image link" OR "pdf link" based off the [type] column returned in the record?
table: pk Name Type (image or pdf) URL Description URL_Thumbnail (if image) GroupId (associate these records to each other) OrderNumber (order of these records within their GroupId)
