View 1 RepliesHow to Sort The datatable in asp.net. after binding the dataset values i have stored into one table how can i sort the values of the dataset in asp.net with C#
View 4 RepliesTried several different ways to do this but am just not seeing it. Proably a quick solution for someone more skilled than me.
I have a gridview generated from a datatable. One of the columns is "client name" whose data is generated from a class.
I added a link button for the column header that fires a sub that should sort the datagrid, but is not.
Here is the code I have so far that creates the gridview which works fine:
Private Sub PopulateCaseListGrid()
'Kill the existing DataSource, in case of a page reload
gvCaseList.DataSource = Nothing
'Create a datatable with whatever column you want to use

I have a manually binded gridview, which I set AutoGenerateColumns=False. I then tried to set AllowSorting=true at runtime, but it wont work.
My gridview are created during runtime.
I want to orderby the list. Today date is on the top and then next date and all dates but when today date is passed then it comes on the end of the list. Is there any formal query in linq or some other code is used to achieve this?
08/01/2015
09/01/2015
but when today is passed then it automatically go to end and next today date is on the top

View 1 RepliesJust 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:

I'm looking for the best way (Performance) to do gridview columns formating RunTime /Dynamic depending on the datatable Columns type ,I want to bind the datatable to a gridview and format the Date columns to short date, and currency columns formatted with comma ex 10,000.00 inplace 100000.00 at datatable the column type is double run time (without converting them to String) since I do a filtering and sorting at these columns.
View 3 RepliesI have a repository that contains all of my LINQ queries for this project that I am working on. I am able to get the LINQ results to a DataTable and bind that to a gridview for displaying the data. Now I need to make the gridview sortable. I have set AllowSorting="true" and I have the OnSort event handled in a routine in the codebehind.
View 2 RepliesI have a datatable,columns are(User_id,Name,Address,DOB)
values like(12,abc,delhi,22/2/2000)
(14,pqr,mumbai,13/3/1989)
(8,klm,banglore,17/5/2001)
(9,asd,pune,12/9/1999)
Now I want to sort these rows on DOB in descending order..how can i do so?
My Grid is bound to a collection type datasource. When I try to sort the Columns in the Grid I get Javascript error saying sorting event not implemented. Why is the default inbuilt sort functionality not working which worked fine when I directly used a sqlDataSource using smart tag. Do I have to write some code to achieve sorting ?
View 1 RepliesI'm looking for a way to sort the rows of a datatable without setting the DefaultView.Sort to a specific column. I have a datatable in session that users can add records to. I want them to be able to sort the data by clicking on a button. But new records added after that need to show up at the bottom of the list until the sort button is clicked again.
View 2 RepliesI have a page which lists all the files in a particular folder (all PDFs), using a data-table and gridview.
I'm currently sorting this table by the filename (by using a dataview), which isn't that helpful, and I want the gridview of files sorted by the file created or file modified date (as recorded in Windows).
If that's not possible, a second option would be to extract the date from the file name string (no problem doing that), and sort the dataview/datatable or gridview based on that. Example Filename: DailySalesReport-1-15-2010. My only hangup with this is how do I sort on date, when it's a string value? Convert to date? How would I sort the whole dataset based on this converted value?

I have a function that constructs a datatable from a file that the client uploads. And I want to bind that datatable to a listview but I'm not sure what I'm doing wrong... Say, the datatable is like:
FirstName LastName
John Smith
Here's how my aspx looks like:
[Code]....
In my names.aspx.cs file, I do: lvNames.Datasource = dt; //dt is a datatable
lvNames.DataBind();
When I run my aspx page, the listview is empty, is there something obvious I'm doing wrong?
I'm not having much luck trying to bind data to an <asp.Calendar> using a datatable. I've tried it on a <as.Label> and it works fine.

View 7 Replies I have a DevExpress WebChart Control that binds to a DataTable. The chart control renders fine from the DataTable until I try to import data from a details view(i think the chart control renders before the detailsview?).
Here is three renderings.
Chart 1. just rendering from the datatable
Chart 2 The sqldatasource gets its para. from the values of two label controls to render the detailsview. The detailsview renders fine
Chart 3, the problem comes in when I try to extract the values from the DetailsView to populate the Chart, I loose the value. I am assuming the the datatable is built before the rendering of the detailsview? Lost at this point.

my repeater binding repeated rows.
TableAdapters.myorderTableAdapter tblerows= new TableAdapters.myorderTableAdapter();
DataTable dt = tblerows.GetDataByUserName(username);
DataTable outputTable = dt;
for (int i = 0; i < 4; i++)
{
outputTable.ImportRow(dt.Rows[i]);
}
Repeater1.DataSource = outputTable;
Repeater1.DataBind();
from the above code i got number of rows for the seleted username. so i need to show only resulted rows. here repeater1 repeating my rows.
I have seq no col in the datatable.how can i order by the seq no so that re-arrage the datatable.or other method have the sort function.and then bind to repeater.
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"
How do I sort a data table based on a particular column which has integer values in ascending order?
I wrote this:
leadtable.DefaultView.Sort = "Id"
But it doesnt seem to work, it displays fine but when i get try to get the values of the sorted datatable in an array they dont come in an sorted ordere Datatble is defined as:view plaincopy to clipboardprint?
I am trying to add many rows in the gridview by clicking a Add button in web form by takeing the value from the textbox then add it to gridview but i couldn't because it accept one row only so how can I let the gridview accept more than one row in every click to the button.

I've coded a GridView in the markup in a page. I have coded a DataTable in the code-behind that takes data from a collection of custom objects. I then bind that DataTable to the GridView. (Specific problem mentioned a couple code-snippets below.)
GridView Markup:
<asp:GridView ID="gvCart" runat="server" CssClass="pList" AutoGenerateColumns="false" DataKeyNames="ProductID">
<Columns>
[code]....
Goal: I'm basically trying to find a way to update the data in my GridView (and more importantly my cart Session object) without having to do everything else I've seen online such as utilizing OnRowUpdate, etc. Could someone please tell me why gvCart.Rows is empty and/or how I could accomplish my goal without utilizing OnRowUpdate, etc.? When I execute this code, the GridView gets populated but for some reason I can't access any of its rows in the code-behind.
