Forms Data Controls :: Sort Gridview Generated From Datatable?
Mar 12, 2010
Tried 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 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
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.
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:
I'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.
I 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.
I 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 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.
I have a gridview with data. I want a button which is not part of the gridview. Then if I press a button the gridview is sorted by two colums. i.e column1 ascending column2 descending.
I am not looking to work with a Sqldatasource as I use a data access layer. So the sort would have to be from a datatable and databind or directly with the gridview.
I 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?
The values are number but varchar, for example '100', '73', '87'. When i see the data this return 100, 87, 73, when should by 73, 87, 100 how can i sort the data????
I want to create simple rating page where player's place,name and rating is displayed. I've created database with ID,Name and Rating Columns, binded Gridview to this database and created TemplateField "Place". With following code I've created numbered list for Place:
protected void Page_Load(object sender, EventArgs e){ for (int i = 0; i < GridView1.Rows.Count; i++)
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.
i am having a gridview in which all columns get dynamically added, i applied sorting in it, all column added as boundcolumn get sort properly but two column which are added as templated column do'nt get sort. Though my dataview have these column as it is.
I am using gridview created by visual components. I have registered gridview_onsortclick event during the page initialisation, but when i try to click on the header of any column, this event does not get fired at that time. This event gets fired only after all the controls, sorting query is generated, filling the current dataset is done. But the same event is getting fired before query is generated and dataset is filled,for the other page. And one more thing to add with it, I want the sort function to be done on the whole dataset regardless of current page. Why is there such a difference in both the pages?
Is there a way to Sort a Gridview by a Calculated Column? I have a gridview with template fields using lablels and a linq datasource. Those columns sort just fine. I can not get the Calculated column to sort, because there is no sort expression to use...
