[Solved] Treeview clientside select unselect nodes with checkbox

Hi

I am using Telerik tree view control with checkboxs.
What i need is when i select the parent node it should select all the child's nodes like wise unselect also.
I am using this javascript code

function UpdateAllChildren(nodes, checked)
{
   var i;

       for (i=0; i<nodes.get_count(); i++)
       {
           if (checked)
           {
               nodes.getNode(i).check();
           }
           else
           {
               nodes.getNode(i).set_checked(false);
           }

           if (nodes.getNode(i).get_nodes().get_count()> 0)
           {
               UpdateAllChildren(nodes.getNode(i).get_nodes(), checked);
           }
       }
       if ((nodes.get_count()==0) && (nodes._parent._parent._parent!=null) && (!checked))
       {
        nodes._parent._parent.set_checked(false);
       }
}
if the selected node has more than 200 child Nodes (nodes.get_count() > 200) then i am always getting this error

Hi,

I am trying to modify some of the css classes for radgrid. Can someone tell me which selector I should be using to modify

Radgrid_Vista .rgExpand,
RadGrid_Vista .rgCollapse,
.DetailTable_Vista

Is it documented anywhere so that I can refer to it in future.

Many thanks,

Anu

re-adding columns that have been made visible

Hi,
Is there anyway of making visible columns that have been previously been made invisible programmatically.

We have a show all button that we would like to make all columns visible, however once they have been made visible = false, this can't be changed.

Keyboard Access not working on Listbox

Hi,

I checked on the Telerik Online Demos - Keyboard support never seems to be working:
Listbox -> Functionality -> Keyboard Support,
http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/keyboardsupport/defaultcs.aspx
and, Listbox -> Functionality -> Transfer
http://demos.telerik.com/aspnet-ajax/listbox/examples/functionality/transfer/defaultcs.aspx

On pressing Tab Key / Shift-Tab, neither the LIstboxes nor the ListBox Transfer buttons seem to be ever reached by the Keyboard.
This is very high priority for my customers since they purchased Telerik to provide Universal Accessibility Compliance and we're stuck with this issue now.
Any helpl would be greatly appreciated.

Thanks and Regards,
Veenu Munjal

Combox and DatePicker appearence in IE8

Hello,
I am using RadCombobox and DatePicker in my project. I create the controls at runtime (code behined). Also i have downloaded the latest version of the rad:controls. When i run my project in FireFox everything goes fine, but in IE 8 the controls show a weired behavior. It seems that either skins dont apply or what so ever. i am sending the screen shots for how radcombobox and date picker appears. Also there is another issue when i uplaod my project on live, the rad combobox doesnot work properly, i.e, neither it postback nor allow me to make any selection of items (as i have use checkboxes with items). I am using the trial version.
Below is the code where i create both the controls.

For DatePicker

RadDatePicker rdDateTime = new RadDatePicker();

rdDateTime.ID =

"rdDateTime" ;

rdDateTime.EnableTyping =

false;

rdDateTime.Width = 150;

For Combobox:

RadComboBox ddlValue = new RadComboBox();

ddlValue.EnableEmbeddedBaseStylesheet =

true;

ddlValue.EnableEmbeddedSkins =

true;

ddlValue.Skin =

"Outlook";

ddlValue.Width = 150;

ddlValue.ID = "ddlValue" ;

ddlValue.ItemDataBound += new RadComboBoxItemEventHandler(ddlValue_ItemDataBound);

ddlValue.AutoPostBack = true;

ddlValue.SelectedIndexChanged +=

new RadComboBoxSelectedIndexChangedEventHandler(ddlValue_IndexChanged);

Now kindly plz tell me how could the look of controls be set.
Thanks in advance
