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.
good example of the listview manual sort logic?
i would like to sort a listview. i don't have a datasourceID. i bind the datasource manually. i think of using jquery(tablesorter) but i don't know how to use it.
View 1 RepliesI have the below code that works for an asp.net repeater but I need to convert the logic so it works for an asp.net listview control...possible? Unfortunately, the same code throws errors when placed within my listview's itemdatabound event.

Ive an page with listview.. i'm performing sorting in itemdatabound event like below:

I want to sort with multiple columns.
How to make a sort (asc / desc) in my ListView through a dropdownlist?
View 2 RepliesI have a button that I would like to click and will put my Listview list in Descending order. However; when I click on the button nothing happens.

see the following code:

I have another 6-8 fields for the same listview. Due to the amount of fields, some of the field heads are wrapping and are not following the center alignment.
Is there a way I can center align the fields?Also, my listview does not sort. Is there something I am missing here?
I have a Listview control that DataBind programatically... ie I am NOT using SqlDataSource or such... I am attempting to sort a column... clicking on a link button that fires the "Sorting" event. So, after cliking on the column heading... I end up in this routine, where I hardcoded the .Sort = values (just for testing). The code is executed... but the RESULT show via Listview remains the SAME. No change!
How to fix this? I've seen some other posts examples that uses this event (ListView1_Sorting) and then sort via LINQ. I am not ready to try that...
Just want to know why dsPaymentList.Tables[0].DefaultView.Sort does not work?
I followed the example at: [URL]
protected void ListView1_Sorting(object sender, ListViewSortEventArgs e)
{
string sortExpression = e.SortExpression + " " + e.SortDirection;
DataSet dsPaymentList = new DataSet();

I have a simple dynamic gridview with following code -
GV = new GridView();
i read Matt Berseth article also i downloaded this source. But i can not do sorting event. Everything is ok but sorting is not working.

I have a column of varchar type, records like DRT1000,DRT1001,DRT900,DRT922....... Records not in proper order..I need to sort this record in descending..
View 4 RepliesI am trying to populate the ListView using LinqDataSource data source but the issue I am having is.I need to load the listview on Search button click action.
IN the page_load I kept like this:
===========================================
LinqDS.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDS_Selecting);
protected void LinqDS_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
e.Result = ObjectDS;
}
=============================================
This works fine but this happens on page load,i want this binding to happen on button click?is there a way to do this?
Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.
I have 1 Gridview that displays 10 different scenarios based on what button is clicked.
I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.
I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.
I tried this:
Tried setting gridview1.sqldatasourceid = null; gridview1.allowsorting = false; gridview1.databind();
Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;
I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:
[Code]....
Here is an example of just one of those SLQ statements inside GetSQLQuery:
[Code]....
what's is better?That I put my business logic in the sqls(DataStore) or in the C#.DataSore:
[Code]....
What's faster and better?
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.
I want to compose data myself without using any DataSources. I want to display it in ListView. How to implement the DataPager to function properly? I tried implementing PagePropertiesChanged of ListView, but it doesn't work.
View 2 RepliesI have an array that I need to display using a feature like listview. Is that possible? I need to be able to display a "temporary" list of information that the user may add or delete entries. Once they approve the list I will loop through the list and store the information in a table.
View 4 Repliesi have the table with the following fields:
FromGrams
ToGrams
Price
CountryID
suppose consider the table have the value as follows:
FromGrams=10
ToGrams=100
Price=0.25
CountryID=221
if suppose user adding new range that have the value like follows:
FromGrams=50
ToGrams=120
Price=0.95
CountryID=221
then the result table will like this
FromGrams ToGrams Price CountryID
10 50 0.25 221
51 120 0.95 221
like that all conditions have to satisfy

I am using a ListView and i want to get my datatables sorted by clicking table headers. I am binding my ListView to DataSet via DataSource peoperty of ListView.I donot want to use ObjectDataSource or SQLDataSource Controls.
View 2 RepliesI have some dropdown list boxes that I need to fill with data from a database but I also need the first option to be "Show All"... So I need to combine using a datasource and manually adding an item to the top of the list. I have tried two different ways with no luck:
1. with the appendDataboundItems = true, on aspx page, and below code in codebehind:
//lstClass.Items.Clear();
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.
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.
View 7 Repliesso instead of a datasource control, I have a Data Access class that I'm using to populate the ListviewI added a datapager and everything pretty much works until I hit the first or last button. Then, I get the following error: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/>Also, Something was mentioned about ClientScriptManager.RegisterForEventValidation - - couldnt' really find an implementationI tried setting:EnableEventValidation="false", but then, all I got was squirelly interaction with all the numbered links (sometimes having to double click them, etc) - no matter what I tried from there on out, even when I removed the enableEventValidation property altogether.
View 7 RepliesFor example:

When I run this the error is 'Invalid column name 'assigned'.'Yet if I load up Microsoft sql server management studio and run the query against the same db:

I get the data I was expecting and the column does exist?
I'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?
