GridBound Column value in ItemCommand Event

Hello,
           I have used radgrid on my page.
           I have four GridBoundColumn which are bound with database column field.

           e.g>.
                   <telerik:GridBoundColumn DataField="Col1" HeaderText="Col1" ReadOnly="True" SortExpression="Col1"
                                            UniqueName="Col1">
                   </telerik:GridBoundColumn>
           Now, i want to retrive this GridBoundColumn values i.e Col1 Value in Grid's ItemCommand Event
   i.e.,
                    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
                    {
                             // Col1 Value
}


Please reply me as soon as possible

Thanks & Regards,

DragDrop not working inside of Ajax-ified TabStrip/MultiPage

All,
Using the example online, I am able to get the DragDrop feature of the Grid working just fine in it's own page. However, when I put it inside of a control instead of a page and bind the control to the TabStrip/MultiPage using Ajax (so that only one control is ever loaded at a time) I receive a javascript error from within the Telerik .js files that it cannot find the grid. I have tried everything I can think of to figure this out, including walking through the javascript at run-time) but I can't seem to produce any errors from the javascript on the control itself.

Has anyone else been able to get drag/drop grids working in an Ajaxified MultiPage? If so, can you please post how. I'm hoping that I'm just missing something small and mundane...

Thanks,
Tom

Databinding w/ParentID Issue

I am trying to get my treeview to databind using the settings below. I keep getting the error listed below.
"A critical error has occurred.
This constraint cannot be enabled as not all values have corresponding parent values."

If I remove DataFieldParentID the treeview does bind and shows a list. I tried using 0 and NULL for my parents. Any suggestions?

List I get if I remove the parentID:
Management
General
Detail Orders
Test

RadTreeView1.DataSource = tree.Treeview

RadTreeView1.DataFieldID =

"rID"

RadTreeView1.DataFieldParentID =

"ParentID"

RadTreeView1.DataTextField =

"Text"

RadTreeView1.DataValueField =

"url"

RadTreeView1.DataBind()

rID ParentID    Text                  url
1    0               Management     NULL
2    0               General             NULL
3    2               Detail Orders    ~/Test.aspx
4    1               Test                  ~/Test.aspx

Filtering doesn't work

I set a AllowFilteringByColumn property to be "true" on Client-side but when I put character on filter box and choose any filtering function, it doesn't work.

Populating hierarchical RadGrid with dropdownlists

I'm currently populating a hierarchical radgrid with two SqlDataSources (one for my MasterTableView and the other for my
DetailsView). I have the values of my DataKeyNames MasterKeyFIeld, DataKeyFiled all matching. Initially the page works as
expected. In addition, I have a few dropdownlists on the page that I would like to re-arrange the data on my grid by soon after
the user clicks a button. Once the user chooses the desired options from the dropdownlists and clicks the button, through codebehind
I'm changing the SelectCommand of the sqlDataSource and doing a RadGrid1.DataBind() on both DataSources.
my code in my vb page looks something like this:

SqlDataSource1.SelectCommand = "Command"
RadGrid1.DataBind()
SqlDataSource2.SelectCommand = "Command"
RadGrid1.DataBind()

After the button click, The MasterTableView applies the new SqldataSource that I set in codebehind(SqlDataSource1), however, my DetailsView still contains the information from my initial SqlDataSource2 Select Statement. I need that Data to be populated as well.
Any help/suggestions i would really appreciate, thank you

How can I specify a CSS class for a grid hyperlink column

Hi,

I have seen some examples about changing the look of a link column by using CSS selectors. However, we have a grid that will be used on different pages for different data.
We need to be able to set a CSS class on the column the same way it can be set for the Grid itself or the Header and Footer.

I cannot see a CssClass property on GridHyperlinkColumn. Is there any other way of specifying the CSS class for the column?

Thanks,
Dewang
