View 4 Repliesi 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 a simple dynamic gridview with following code -
GV = new GridView();
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 read Matt Berseth article also i downloaded this source. But i can not do sorting event. Everything is ok but sorting is not working.

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:

Here is an example of just one of those SLQ statements inside GetSQLQuery:

View 3 RepliesI am trying to sort a DataTable. If I declare a DataView and use the following approach it works perfectly:
Dim dt As DataTable = getData()
Dim dv2 As New DataView(dt)
dv2.Sort = "surname, name"
dt = dv2.ToTable
I wanted to do this without using a DataView though if possible to reduce the impact on resources. I tried the following approach but it doesn't work. I might be writing the code wrong so
Dim dt As DataTable = getData()
dt.DefaultView.Sort = "surname, name"

I have encountered a problem about "order by" sorting in SQL. As some of the items (strings) in a dropdown list contain negative sign on the left, it is surprising for me that the SQL server cannot sort the items in an alphabetical order and as a result I was forced to set the property value (IsSort = False) of the Ajax ListSearch, which slow down the searching speed a lot. Below are examples of two of the string items with a negative sign on the left.

View 1 RepliesI am using gridview to display some columns with autogenerate column as 'true' and not added boundfields,headers.
And i am used stored preocedure for data source in gridview and i used dataset for gridview databind.
The gridview columns comes dynamically for each time.
I'm having a problem sorting a dropdown that I've bound to a SQL Server data source. I've narrowed the problem down to the fact that I have a static item at the top of the dropdown with the data-bound items appended afterwards. If I remove the static item (<asp:ListItem Value="-1" Text="All" />) the ORDER BY part of the select clause works fine. How can I get around this issue? What I would like is to have the "All" static item at the top of the list with the data-bound items sorted alphabetically afterwards. I'm using Visual Studio 2010 and ASP.NET 4 if it makes any difference.

how to sort DataGrid column. (Say like FirstName) I have done snippet like: (see Bold text) For HTML :

</Columns>

private void dtgCustomerSearch_SortCommand(object source, System.Web.UI.WebControls.DataGridSortCommandEventArgs e)
{
SortExpression = e.SortExpression;
BindTheGrid();

I have 12 columns in a grid i want sort 3 of them when user clicks on Header, how can i do this.
U want these columns to be sort WOnumber,DD,PO.
I have a datatable which contains the summery row as well. I just assign the datasource property of a gridview and call databind method to fill and display the records.
Now, when I applied sorting through dataview to the gridview, the sorting happens along with the summery row, which is a normal behavior. As a result the "Total" - column took place inside the data some times. I want to prevent this.
The best way out for that can be done by creating the summery row at grid view row databound. But unfortunately I could not change the datatable as per this requirement.
Can the dataview sorting exclude the last row of the datatable through any process?..
I'm a newbie to .NET, so the solution might be really trivial. I have a database, I have an Entity Data Model, I add in my Index.aspx page an EntitryDataSource and a GridView. I connect them and everything works fine (the data is displayed as expected). The problem is that clicking on the coulmn name or on the pagination lists doesnt do a thing... Although I did set the properties AllowSorting="True" and AllowPaging="True". I also tried with another datasource type (SqlDataSource) and the same problem.
