[Solved] Paged RadGrid defaulted to inplace edit binding RadToolTipManger

Hi Telerik Support,

I am trying to Bind RadGrid TextBox to a RadToolTipManager's targetcontrols collection as per the demo in the Grid's ItemDataBound handler. I also want the Grid to default to edit mode as per the other demo in the Grid's pre-render event. The problem that I am having is that the DataBind/Rebind which is necessary to put the Grid into edit mode is calling the Databound event - its a bit chicken and egg - is there anyway around this? also could you give me a pointer to activating the tooltip on entering and leaving the textbox using the tab-key ie onkeydown.

Kind regards,

Ashley

Set page size greater than items count

The problem is that we can’t set the Page Size greater than the Items Count.

We want to be able to set the page size 10 even if there is 4 items in the source list.

Steps to reproduce: bind to the grid the source with 4 items, try to enter 10 to the Page Size texbox, press Change button.

Actual result: the value of the textbox is turned back to previous value.

Expected result: the page size is changed to 10

The aspx code :

<telerik:RadGrid ID="dgdTransList" runat="server" AutoGenerateColumns="True"

GridLines="None" EnableAJAX="true" PageSize="5" ShowFooter="true"

AllowPaging="true"

>

<PagerStyle

Visible="true"

Mode="NextPrevNumericAndAdvanced"

AlwaysVisible="true"

/>

</telerik:RadGrid>

The cs code :

void dgdTransList_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

ArrayList list = new ArrayList(new object[] { "one", "two", "three", "four" });

dgdTransList.DataSource = list;

}

Can you please tell us is there any workaround?

[Solved] PanelBar - postback on expansion only

I have a panel bar which is divided into sections. Within each subsection there are RadPanelItems that are links to other pages. One of the things I do is to put a number such as (59) next to the item text to indicate how many items will be listed when the user clicks on the link.

With the aid of RadAjaxManager I am updating the links via an Ajax call when the section is expanded. i.e.I am hooking into the ItemOnclick event and updating the links in the expanded section. However, an Ajax postback occurs when I contract the section as well - it is this postback that I want to avoid.

Any suggestions on how to do this?

Thanks.

Any plans for "trendy" skins?

Hi! RadWindow is a great component. However, the skins look terribly outdated nowadays. Does Telerik have any plans to add more trendy styles? E.g. border shadows, a close button stretching beyond the main window area, etc? And: Why can't we get the simple (and great) style of a Tooltip into a RadWindow.

Thanks, Stephan

PS: We use tooltips and modal dialogs heavily and in many cases either one can do the same stuff. These two components should simply be merged together. My opinion.

Clientside, initiate RadTreeNode edit

I'm adding a treenode like this;

    
                function AddNode(parentNode) { 
        
                  var tree = $find("<%= tvCategory.ClientID %>"); 
        
                  tree.trackChanges(); 
        
                  var node = new Telerik.Web.UI.RadTreeNode(); 
        
                  node.set_text("New Node"); 
        
                  node.set_imageUrl("<%= NodeImageURL %>"); 
        
                  if (parentNode == null) { 
        
                    tree.get_nodes().add(node); 
        
                  } 
        
                  else { 
        
                    parentNode.get_nodes().add(node); 
        
                    parentNode.expand(); 
        
                  } 
        
                  tree.commitChanges(); 
        
                  node.BeginEdit(); 
        
                }

I'd like to be able to initiate the editing of the newly added node in order for the user to easily change the node text; "New Node"

Is it possible, can you provide the js code?

[Solved] RadComboBox AssociatedControlID

I am trying to associate a label with radcombobox like in this example.
http://www.telerik.com/help/aspnet-ajax/combo-associate-label.html

it's working but when i change the selected item it doesn't change in the radcombobx, the first item is always shown as the selected.
i tried this example also in an empty project and it doesn't work.

<asp:Label ID="Label1" runat="server"
   Text="Select a country"
   AssociatedControlID="RadComboBox1_Input">
</asp:Label>
<input type="hidden" id="RadComboBox1_Input"
   runat="server"
   style="display:none" />
<telerik:RadComboBox ID="RadComboBox1" runat="server">
   <Items>
       <telerik:RadComboBoxItem Text="USA" />
       <telerik:RadComboBoxItem Text="Germany" />
       <telerik:RadComboBoxItem Text="Canada" />
   </Items>
</telerik:RadComboBox>

The problem i think is the <input /> field

Thank you.
