Web Forms :: Can't Get Dropdownlist To Sort
Mar 12, 2010
I am using Visual Studio 2008 and SQL Server 2008, I have a drop down list on my page that gets its data from SQL. My SQL tabel only has 2 columns, "HeaderId" and "Header". So on my drow down list I have the value field set as the "HeaderId" and the text field set as the "Header". What I need now is that when it is bound to the list to be in order of the "HeaderId". I tried doing and ORDER BY but it did not work. What can I do, is there a better way of doing this? Here is my code to populate the list:

I'm having a problem sorting a dropdown that I've bound to a SQL Server data source. I've narrowed the problem down to the fact that I have a static item at the top of the dropdown with the data-bound items appended afterwards. If I remove the static item (<asp:ListItem Value="-1" Text="All" />) the ORDER BY part of the select clause works fine. How can I get around this issue? What I would like is to have the "All" static item at the top of the list with the data-bound items sorted alphabetically afterwards. I'm using Visual Studio 2010 and ASP.NET 4 if it makes any difference.

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.

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:

Here is an example of just one of those SLQ statements inside GetSQLQuery:

I am dynamically binding the treeview using DOM.
I m populating the tree by sayin treeview1.nodes.add(Treenode)
After this, i need to sort them alphabetically. I have followed this ref:[URL] but I was not able to understand how to do it only for parent nodes, since I don't have child nodes.
Moreover I m not able to get property sort().
How do I achieve this?

how to sort DataGrid column. (Say like FirstName) I have done snippet like: (see Bold text) For HTML :
<asp:DataGrid ID="dtgCustomerSearch" runat="server" AllowSorting="true">
<Columns>
<asp:BoundColumn HeaderText="CustomerID" DataField="CustomerID" />
<asp:BoundColumn HeaderText="First Name" DataField="FirstName"

SortExpression="LastName" />
<asp:BoundColumn HeaderText="Phone No." DataField="Phone" />
<asp:BoundColumn HeaderText="Email ID" DataField="EmailID" />
</Columns>

private void dtgCustomerSearch_SortCommand(object source, System.Web.UI.WebControls.DataGridSortCommandEventArgs e)
{
SortExpression = e.SortExpression;
BindTheGrid();
}
string SortExpression
{
set
{
if (ViewState["SortExp"] == null || value != ViewState["SortExp"].ToString())
{
ViewState["SortExp"] = value;
}
else
{
ViewState["SortExp"] = value + " DESC";
}
}
get
{
return ViewState["SortExp"] == null ? string.Empty : ViewState["SortExp"].ToString();
}
}
