Forms Data Controls :: Sorted Gridview Not Displaying All Rows?
May 18, 2010
I see from google that this is a common problem. I have a SQL server database that contains 26 rows of data. Two columns, the first is PK and an identity column (keys numbered 1 to 26) and the second column is a text field (nchar(10)) containing a letter of the alphabet (A..Z). The letters were inserted randomly to simulate sql being unsorted by default. I have a query that returns all of the data ordered by the letter column ascending. If I execute the query in sql server I get 26 rows orderd A..Z.
I have a gridview that is set up for paging (page size = 15) and sorting. When sorting is disabled, all data is correctly displayed on the gridview, 15 rows on the first page, 11 rows on the second page.
If I enable sorting, I get 15 rows on the first page and 11 rows on the second page, however on closer examination I find two letters missing and two letters duplicated on both pages. If I navigate to page two, then back to page 1 I find that the data is then shown correctly and the missing letters are back.
Has anyone struck this issue? I am thinking that the sort is not being initialized correctly, but am not sure where to look.

I am building a SortedList object for use as the DataSource of a GridView control. The key-value pairs are being built manually with the "key" fields being inserted in already sorted order. The "key" column is invisible with the "value" column the single displayed data item. I set the DataSource property of the gridview to the sortedlist and call the Bind method. The gridview then displays the data in random fashion!

So I've been teaching myself ASP.NET and VB for about 3 weeks now, having trouble with datatables, not sure how to get the rows to line up like I think they should. My code:
[Code]....
Which gives me the data output I want, but the days are adding rows underneath the previous day instead of lining up side-by-side. The idea is that once it's working I'll replace the specific dates with calendar controls. The gridview currently outputs like this:

I am having a DOB field in database of type Datetime.I am retrieving this into a gridview .I want to display only date into the gridview in 'DD-MM-YYYY' format and that to in sorting order. How can I do that. I know that by converting DOB to varchar and using SQL Date formats codes(103,105...) I can do that but I can't able to display in sorted order as it will check only the date part and sort the dates. It will not chk the month & year. And I also want the user to insert the date in 'DD-MM-YYYY' format and this to be stored in database. How can I do this? Pls respond me ASAP.

I'm trying to extend the GridView control to enable sorting and paging for any situation.
When using my control I am fetching data from a database and filling a DataSet with it, then binding the GridView upon every page load. My first question would be, is this the correct approach?
To sort the GridView I am overriding the OnSorting method which stores the sort expression and direction in the ViewState, then creates a DataView and utalises the Sort method to sort the underlying data. It then sets the Data Source to this DataView and rebinds the GridView.
Paging is handled by OnPageIndexChanging which simply sets the PageIndex property and again rebinds the GridView.
My problem is; when any control causes a postback my GridView is no longer sorted, presumably because it is persistently rebound. If I don't rebind it then the GridView is empty on postback since the data isn't automatically stored in the ViewState. I have considered saving the data source in the ViewState but I would assume that this is bad practice for large amounts of data? - also DataViews are not seralisable.
The only solution I can think of currently is to override OnDataBound and sort the data every time. This results in a double sort when paging triggers a postback which seems inefficient. Code illustration of this below,
[Code]....
I'm looking for the cleanest 'best practice' solution as this is a learning exercise more than anything else.

So I have a gridview that is sortable. I also have enabled it to export to excel. The problem is that it exports the original datasource and not the sorted data on the screen. What I need is when the export control is fired, the exact gridview or newly sorted gridview is sent to an Excel spreadsheet. Here what my excel export looks like:

I've got a Gridview bound to an objectdatasource. Sorting is enabled in gridview, but objectdatasource isn't doing any sorting. I can pick up the unsorted datatable from the Selected event of the objectdatasource, but I really want the sorted version. Is there any event on the gridview where I can access the sorted dataview it must be using internally?
Why am I asking? We're using paging as well (i.e. truncated data in gridview) and I want to loop through the full sorted dataview to find the primary key value to set selectedindex.

I have a gridview which displays images as shown in the code below. When the page loads the images load fine. But when any of the columns are sorted, the images are not displayed. In the page source view the grid still hold reference to the images when they were first loaded.
How do i bind the images so that they sort when the other columns are sorted.

I have a gridview and the gridview contains some boundfield, templatefield, checkbox and an update command button.
When I click the update button, I want to update only 2 columns. So I made rest of columns readonly=true.
BUT, there is a template field and I am changing the value of the template field from code behind. like below
[Code]....
I do not want to update the above column. so when I click update button, the rows having value more than 0 is working fine.
BUT The rows displaying "Expired" (value less than 0) showing error. It says "Object reference not set to an instance of an object."

Using ASP.NET 4.0 with C#.
I have a GridView and have sortable columns. When a column is sorted the GridView automatically selects the top row, however the SelectedValue is still representing the row before the column is sorted. The SelectedValue of the GridView only gets changed when a row is selected, but I want that to happen when the GridView is sorted.
For example if I have this in my code:
[Code]....
itemId is populated with the old SelectedValue not the new one after the GridView has been sorted.

I need to produce a from where I can add multiple parts. Each time a user enters a part number, the description should be populated. The user can then click add and this part and description will be shown below. They have the option to add as many parts as they require. Once all parts are added the user fills in some general info eg description and then once a submit button is clicked all part info will be inserted into a table and general info will be inserted into another table with one unique ID.

I have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.

Im displaying a Gridview full of data but the column "Country" is displaying the CountryID and I want it to display the Country 'Name'", same with State/Prov and a Status column I have. I've looked around at BoundField Properties and such and can't seem to find where I can configure this. Is it straight within my DataSource? Here's my code:

Here is my DataSource Code

Is it within the SELECT statement of the DataSource where I can need to configure using "Country" not "CountryID"or "Status" not "StatusID"?
