Forms Data Controls :: Exclude A Row From Dataview Sort?

Mar 5, 2010

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?..

Forms Data Controls :: Sort DataView Ascending With Nulls Last?

Aug 16, 2010

how to sort a datatable (dataview) so that the second column is ascending but nulls are last.

I'm trying to do the following Date1 ASC, DATE2 ASC (but if DATE2 is null it is last in this Date1 group)

Note: Date1 can never be null so a Date2 that is null should still be grouped in with its Date1.

Web Forms :: Sort Datatable Without DefaultView.Sort?

Apr 20, 2010

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.

Sort Datatable / Dataview / Gridview Of Files Based On File Modified Date?

Aug 2, 2010

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?

Forms Data Controls :: Gridview Sort Expression - How To Reset A Gridview Or Prevent It From Doing A Sort

Sep 23, 2010

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:

Correct The Sort Order Of Sql Dropdown List?

Jan 5, 2010

I am trying to correct the sort order of my ASP.NET drop down list.

The problem I have is that I need to select a distinct Serial number and have these numbers organised by DateTime Desc.

However I cannot ORDER BY DateTime if using DISTINCT without selecting the DateTime field in my query.

However if I select DateTime this selects every data value associated with a single Serial number and results in duplications.

The purpose of my page is to display data for ALL Serials, or data associated to one serial. When a new cycle begins (because it is a new production run) the Serial reverts to 1. So I cannot simply organise by serial number either.

When I use the following SQL statement the list box is in the order I require but after a period of time (usually a few hours) the order changes and appears to have no organised structure.

C# - Sort Checkbox List On Basis Of Checked Property

Jan 14, 2010

I have a check-box-List which I bind to a master dataTable(DTA)... I have another dataTable (DTB) which has the values that needs to checked in the check-box-List... So I loop through all items in the check-box-list to see if it exists in the DTB and set checked = true for those items that exists. Now I want to show the checked items first in the Check-box-list box and the unchecked items below that. Is there any way I can do it... A similar solution for List-Box could also be helpful. A Javascript hint is welcome too.
