Hi,
I am using Telerik Radgrid with inline Editing feature.

Grid in the edit mode shows update/cancel commands as images.
I would like to disply both updateimage and updatetext.
Currently when I set the UpdateText with updateimage, it shows the text as tooltip when user hovers over the updateimage. I would like to display the updatetext even without hovering over the image.

I would appreciate help on this.

Thanks,
Manisha

Hi there,

i need someone to point me on how if i set  the predefined layout of RadListView on Code behind ?

well actually it does not matter if it has to be on code behind or not the only constraint is that i need to customize my data table (which will be datasource for the list view) on the fly and therefore i think i need to set the predefined lay out on code behind..


is this possible or i just have to create custom layout that will replicate the predefined lay out?

By predefined layout i mean the single row lay out..


thanks in advance guys...

Hi,

I am using RadTreeView with server side load on demand. The issue I am having is I don't want the '+' sign to be displayed for a node if it doesn't have a child node. How can I achieve this with server side load on demand. Below is the code I am using to create root and child nodes.

 ASPX code:

<telerik:RadTreeView runat="server" ID="RadTreeView1" OnNodeExpand="RadTreeView1_NodeExpand" >
                 <ContextMenus>
                <telerik:RadTreeViewContextMenu ID="CM" runat="server">
                <Items>
                <telerik:RadMenuItem Value="CreateSibling" Text="Create Sibling">
                </telerik:RadMenuItem>
                <telerik:RadMenuItem Value="CreateChild" Text="Create Child">
                </telerik:RadMenuItem>
                </Items>
                </telerik:RadTreeViewContextMenu>
                <telerik:RadTreeViewContextMenu ID="EmptyCM" runat="server">
                </telerik:RadTreeViewContextMenu>
                </ContextMenus>
    </telerik:RadTreeView>

c# code:

protected void Page_Load(object sender, EventArgs e)
        {
            try
            {
                if (!Page.IsPostBack)
                {
                    LoadRootNodes(RadTreeView1, TreeNodeExpandMode.ServerSide);
                }
                
            }
            catch (Exception ex)
            {
                RadAjaxManager1.Alert(ex.ToString());
            }
        }

private static void LoadRootNodes(RadTreeView treeView, TreeNodeExpandMode expandMode)
        {
            DataTable data = GetData(new SqlCommand("select Description,ID from Table1"));

            foreach (DataRow row in data.Rows)
            {
                RadTreeNode rootnode = new RadTreeNode();
                rootnode.Text = row["Description"].ToString();
                rootnode.Value = row["ID"].ToString();
                rootnode.ContextMenuID = "CM";
                rootnode.ExpandMode = expandMode;
                treeView.Nodes.Add(rootnode);
            }
        }

 protected void RadTreeView1_NodeExpand(object sender,RadTreeNodeEventArgs e)
        {
            if (e.Node.Nodes.Count == 0)
                PopulateNodeOnDemand(e, TreeNodeExpandMode.ServerSide);
        }

        private static void PopulateNodeOnDemand(RadTreeNodeEventArgs e, TreeNodeExpandMode expandMode)
        {
            DataTable data = GetChildNodes(e.Node.Value,e.Node.ContextMenuID);

            foreach (DataRow row in data.Rows)
            {
                RadTreeNode childnode = new RadTreeNode();
                childnode.Text = row["Description"].ToString();
                childnode.Value = row["ID"].ToString();
                if (!(childnode.Value == e.Node.Value))
                {
                    e.Node.Nodes.Add(childnode);
                    childnode.ExpandMode = expandMode;
                }

                childnode.ContextMenuID = "CM";
                
            }
            if (e.Node.Nodes.Count > 0)
            {
                e.Node.Expanded = true;
            }
            else
            {
                
               e.Node.ExpandMode = TreeNodeExpandMode.ClientSide;
                //e.Node.Expanded = false;
            }
        }

I am using a RadEditor to enable a (pretty unsophisticated) user to generate emails
I have Removed a number of the icons ("tools") that she won't know what to do with i.e. html validator
but I think she will want to incorporate the css she provided us with the site the page is part of
the css renders on the page but when I write the content of the control this is what I get
what do I have to do to get her css into the emails - and how do I tell she has added css styling to her text?

We are having an issue where the checkboxes in a RadComboBox are not checkable in Chrome on an Android tablet.  All other browsers on all other devices we support appear to be working fine.  We are on revision 2012.3.1380.40 of the controls.  Is this a known issue with this version?  Has it been fixed in a newer version?

Thanks,
Kevin

It is a weird issue. I have a page with simple RadBinary image on that. It reads file from the disk and assign to rad binary image. Like this

imgBinary.DataValue = ReadFileToBytes(fullName)

imgBinary.SavedImageName = pi.OriginalFileName

It works fine. Everything alright, but for a certian image, it seems failing. but the weird thing is that it is failing on Chrome only, not IE or FF.

it doesn't display image, but when checked the details in the chrome, I found that it had error in JavaScript. Failed to load resource
and the resource is /Telerik.Web.UI.WebResource.axd?imgid=473d105fe88042cebef7411cd9fc8e53&type=rbi
it is weird that this issue is coming on few Images only and on Chrome browser only. the same thing works fine on   IE and FF.

BTW, I tried to open images in paint and re-saved them (saved to PNG and then saved as JPG back) just thinking that image might not be good, but still not worked. But seems images are good as they do render on IE and FF

any clue?
thanks,
Sameers

Hello,

The WebResource.axd is caching the image data on the server for a couple minutes.  Can this be changed?  We have a security concern where an unauthorized user could possibly view the generated image if they obtained the url.  We only want the image to be generated once for the initial rendering, and not cached on the server (or very briefly) if possible.

Thanks

I have SelectedDateChanged event in code behind and invloking radconfim to with OK and Cancel buttons. The SelectedDateChanged works fine but when I click on 'Cancel' button 'SelectedDateChanged' fires twice. When I click on 'OK' button I am saving the 'Date' in the database. Could you please let me know why this event fires twice. I am using Telerik 2010 Q3 controls.
