Hi,

How can i sort columns in a datatable? I've tried converting it to a dataview and sort, but it doen't get sorted.

Once the user has edited the grid, I have to sort 2 columns in the grid and get those values.

Regards,
Blumen

That function will sort only Row, not the entire Table.

hi,
you should be able to sort the data by using dataview. may be you missed out something...
the code below should work fine:

Dim dv As New DataView(yourDataTable)<br />
dv.Sort = "ColumnName1 desc, ColumnName2 asc"<br />
datagrid1.DataSource = dv<br />
datagrid1.DataBind()

Hi,
You can done this at code behind
Provide id=htmlid runat="server" to head tag

<br />
    <html xmlns="http://www.w3.org/1999/xhtml" id="htmlid" runat=server><br />

From code behind use

<br />
    htmlid.Attributes.Add("dir", "rtl")<br />

to set attribute.

To succeed, we must first believe that we can.

Can someone show me how to read out the contents of a (Belgian) e-Id Card by a web page ?

I would like to create a website where accounts can be created by entering a e-Id card and pressing 'New account'. The system would automatically fill in the web-form.

Thx in advance.

You can use two Hashtable instead of arraylist. And it is good to use question number as key for both hashtables. Then you can easily find answer of each question by the question number.

You are creating controls dynamically. right? If so, you can do a postback using javascript. Use two hidden controls for storing qustion number and selected answer. Set these hidden variables before postbacking the page. Then you will get the values in the codebehind. add this to the selected answers hash table.

Then use simple loop to compare both hash tables
