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.

View 1 RepliesI have a GridView that exports to .csv just fine with the code below. The problem is that I have a TemplateColumn with a TextBox which isn't wrote to the .CSV at all!

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.

When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'.

Let's say I have a DataGrid that looks something like:
<asp:DataGrid ID="SomeDataGrid"
runat="server">
<Columns>
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="Data"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
In this Grid, I set the datasource to some collection that contains a public property called "Data" and do a databind(). Every works as expected.Now let's say I want to set the DataField attribute of the column to a public member, or a property, or some other thing I've computed. What is the easiest way to go about this without creating intermediate objects or adding public properties to the objects in the collection?So what I want to do is something like:
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="someMethod()"></asp:BoundColumn

I've got a typed dataset that populates programmatically based upon dropdown selections from the user, and then is bound to a datagrid. One of the cols is a bit type (indicating whether or not that record is "active"). I would like that datagrid col to be exposed to the user as a bunch of checkboxes, which the user could turn on and off as needed, and then update the entire recordset according upon clicking Submit.
Is converting a dg column into checkboxes a straightforward thing to do?

Summing a column in a datagrid
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)

I had a datagrid and I was hiding columns. This was working fine to show just the columns I wanted.
[Code]....
And then I realised I wasn't paging the data so I ticked that on then above code no longer worked. The Count was equalling 1 with the paging ticked on. Why would that be?
I also used the classic formatting and when I sort the columns the classic formatting goes funny, how can reapply the sorting to make it look classic?
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 requirement to display alphabets above each datagrid column names (like shown in excel).
