when I use 'RowNumber' = ROW_NUMBER() OVER(ORDER BY ColumnName) then due to orderby Column name consume 76% usage. in such case what I have to do? I can see sorting taking much time in execution plan.

View 3 RepliesI have a DataSet comprised of two DataTables. One of the DataTables is further comprised of the results of two different SQL calls. I need to alphabetize the results of those SQL calls. After the seconds set of results is added to the DataTable I tried the following but the end result (displayed on the page) did not alphabetize the returned results. There was no error. Can anyone advise me please. 'programs' is the DataTable name, title is the column name.
programs.DefaultView.Sort = "Title ASC";
The following code is my Grid View AA from aspx page.
<asp:GridView ID="GridView_AA" runat="server" OnSorting = "Gridview_AA_Sorting" OnRowCreated="GridView_AA_RowCreated">
<asp:TemplateField HeaderText="Period Name" SortExpression="PERIOD_NAME">
[code]...
I cannot sort after adding GridView_AA_RowCreated function. Each column of Grid view header-text worked well before I add this Row Created function. If I cut the following code: e.Row.Cells[2].Text = "Period Name";
Sorting works. I want to get sorting without removing this Row Created function. Do you have any brighter solution about my problem?
protected void GridView_AA_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[2].Text = "Period Name"; //Change header text in run-time
}
}
I am able to store the current time of day in a column defined as time with the C# code as:notestable.NoteTime = DateTime.Now.TimeOfDay;The hour, minutes, seconds, and even millionth of a second is stored. But now, I need to retrieve the time and convert it into a string. I tried to use DateTime statements to accomplish this as with:
DateTime nt = notestable.NoteTime;
String FirstT = nt.Hour.ToString() + ":" + nt.Minute.ToString().PadLeft(2, '0');
Regarding the 'nt' variable, I got an error message that said: Cannot implicitly convert type 'System.TimeSpan?' to 'System.DateTime'.Regarding the 'Hour' designation, I changed the definition of 'nt' to 'var' and got an error message that said: System.Nullible<System.TimeSpan>' does not contain a definition for 'Hour' and no extension method could be found.So, how do I access the time from a table and convert it into a string for display in a TextBox?
Situation: SQL database, Linq to SQL class a ASP.NET page with a LinqDataSource and a gridview. The table has a ID field, a date field and a Serialnr field. In my Grid I like to Page on the datefield but to sort on the serialnr field ( or a selectable other field). Is that possible? Standard the paging is always done on the sort field and when you select a different sort field the page jumps back to the first page., and paging is then done over that sorted column.
View 2 RepliesI am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header. In the design I have been given, the column header will not be shown, and I need to be able to give the user to sort this column, by simply just clicking any where on the column.

I have a Gridview with a templated column which contains just a label.
I set the Label1.text during GridView1.RowDataBound based on doing a DataBinder.Eval(e.Row.DataItem,"myColumn") and a calculation off that.
When the user clicks the header I want it to sort based on what's in the Label but instead if seems to be sorting on the contents it was bound to, "myColumn", even though that's not what appears in the grid.
I have a auto column generated GridView in a page, I have a dynamically binded column in that gridview, when page loads then sorting option is available on all other columns except that dynamically created column.

I have a datagrid with two columns ( File Name, and Date Created ). I want them to be sorted when clicked (ASC or DESC). I went into the design view and added the allow sorting feature and added the column names, so they are clickable in the header of the data grid. I also already added the onsortcommand as well.
My datagrid is named dgFileList and the onsortcommand method is named dgFileList_SortCommand.
The procedure that is already loading on page load is a DataSet. (where I think my problem is)I dont have anything in the back end beside the dgFileList_Sortcommand method. From what I have read, it seems like I can't use a DataSet to be sorted...I'm using visual studios 2005, C#, not VB.

I'm currectly tryin to access a specific value in my database in a specific column. I'm tryin to use the primary key of the table to access the actual value in the row of that ID.
The current code:
[Code]....
Just iterates through the table and looking for any row with the boolean 'checkin' value is True, then it takes the 'id' value of that row and stores it into an array. Is there a way that I can access a another entry, and only that entry, in the table with the 'id' stored in the array?
Like if my data base contained and int, primarykey, `id` value, a boolean, `checkedin` value, and a `time` value, is there a way to access, lets say, the row with `id` equalling 3 and and the checkIn value from that row?
