.net - DataGrid - Access Column Count Prior To Rendering?
Oct 1, 2010
I have a datagrid with columns programatically populated. I need access to the columns to modify the sort expression prior to render, but the column count is 0 at every stage I try to access them. Break points are hit, but each check of the count = 0.Have tried the following, accessing in various stages of the page / control life cycle, but in all instances, the column count is 0.
protected void Page_PreRenderComplete( object sender, EventArgs e )
{
if (dgPriceInfo != null)
[code]...

Using ASP.NET Web Forms.I am databinding a DataView to a DataGrid with AutoGenerateColumns set to trueThe final column of the DataView is not rendering.Using the debugger I can see that the column definitely exists in the data grid's datasource. The column is of type decimal and some of the rows in the column have data in them.The column has a column name.The other columns are rendering fine.What's going on?Some more infoFunnily enough, I can set AutoGenerateColumns to false, then just add the columns manually:
datagrid.Columns.Clear();
foreach(DataColumn column in dataView.Table.Columns)
{
datagrid.Columns.Add(new BoundColumn {
HeaderText = column.ColumnName });
}
datagrid.DataSource = dataView;
This works fine. Why can't .NET do this with AutoGenerateColumns?

I have a DataGrid that has event handlers bound to SortCommand and PageIndexChanged. How can I determine if those event handlers are about to be called, say on page_load? These events will fire just fine after page_load, but I'd like to know at page_load if they are to be fired.

I have a grid containing images loaded from database. the images are displayed in the order as they are stored in the database. Is there any way to change the order of the images manually once after they are uploaded to the database.. the admin before publishing the images to front end, should be able to arrange the images as he/she wish and then finally stores them in database.

I have a problem that I cannot seem to resolve. We are using an access database to store data from a Quality Assurance Tool. I need to calculate an average on a specific column in the table, however the SQL statement needs to count the number of records that contain "0.1" and divide it by the total number of records in the table. This data is then displayed in an ASP Page.
The field name is 1.
Here is the SQL:
StrSQL = "(Select Count([1]) FROM cservice Where [1]=0.1) / (Select Count([1]) FROM cservice) As questaverage "

I have a .aspx file with a datagrid in it:
<asp:DataGrid ID="Gifts"
AutoGenerateColumns="True"
runat="server" AllowSorting="True">
</asp:DataGrid>
The .aspx.vb file associated with it fills it in with a datagrid object.
Protected WithEvents Gifts As System.Web.UI.WebControls.DataGrid
Public GiftData As DataTable
Gifts.DataSource = New DataView(GiftData)
Gifts.DataBind()
That all works fine. However I want to format one of the columns with a particular date format. Is there a way of doing that in the vb code? I know I can do it in the .aspx by specifing AutoGenerateColumns="False" and then explicitly defining the columns, but I want to do it in the code as it's more future proof for my application.
