VS 2008 How To Tell What Column GridView Is Sorted On
Jan 4, 2011
I have a gridview control connected to a sqldatasource control. I am allowing the user to sort the columns in the gridview control. The user can click a row and visit another page. When they return I need to set the column sort again. I have seen that I can use the Sorting event to set the sort order of the data when I return to the page in the Sorting event. But before I leave the page where can i get the column it is currently sorted on along with the direction?

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 have a stored procedure in my database that sorts a dataset by distance from the specific address input by the user. The distance is created among each individual users query and the sorting of distance occurs within my stored procedure, the distance is not returned in the output. Is there a way I can create a temporary column that returns the distance so that I can give the user an option to sort by distance?

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.

I have a GridView with a SQLDatasource. All of the columns in the gridview are bound to a field. Now they want a column that is not a field returned but would be two of the fields combined together. How can I do this exactly? Can someone show a line of code to display this in a column?

I have an ASP.net gridview on a webform where user's can select a row. When they select it, the row is highlighted yellow. The problem is that when I sort the table, it sorts properly but the highlight stays on the same line. The data all moves, but the highlight stays put.

I need a textbox for each column of the header row of my Gridview. Then whatever I type in, say the first column is a Surname, the Gridview needs to be filtered by records with only that Surname.

I have a gridview control on .aspx page. Situation is, the columns in the gridview control are not databound. I query the database and load the gridview control using the following code.
GridViewstockcalc.Visible = true;
GridViewstockcalc.DataSource = dataSetstockcap.Tables[0];
GridViewstockcalc.DataBind();
The gridview control shows about 13 columns from the database. But we want the user to be able to edit only one column. Rest of the 12 columsn should be read only. When the clicks one Edit button button, as usual the Update and Cancel buttons should come up. It is not happening. Only the _Rowediting event is getting trigged. Following is the code from my .aspx page. I don't know anything about template columns and not sure if I have to use that concept in my situation.
<asp:GridView ID="GridViewstockcalc" runat="server"
HeaderStyle-BackColor="#444444"
HeaderStyle-ForeColor="White"
onrowcommand="GridViewstockcalc_RowCommand" Height="150px"
Font-Size="Small" onrowediting="GridViewstockcalc_RowEditing"
onrowupdating="GridViewstockcalc_RowUpdating">
<Columns>
<asp:CommandField ShowEditButton="true" ShowCancelButton="true" />
<asp:TemplateField HeaderText="ticker">
<ItemTemplate>
<%# Eval("ticker")%>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID="txtticker" Text='<%# Eval("ticker")%>' />
</EditItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="fhlb_ID" HeaderText="ticker" ReadOnly="true" />
</Columns>

Right now when I bind data to my gridview, I have a column MemberNo that I use in the RowDataBound in another column for creating a link. Anyways, in the DataBound event i hide the MemberNo column. But I also have a routine where I need to loop through the rows and use the MemberNo. Can I unhide the column MemberNo to use for this routine and then hide it again? I assume I cannot use the data if it is hidden right?

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 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:

ASP.NET 3.5
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.
