Hi

Iam creating my own Command Item Template because i need the add new record to open in a RadWindow instead of reloading the entire grid which is needed when doing inline editing.

However i would very much like to use the same picture you use when creating the standard Add and Delete buttons.

How do i Access these pictures ?

    
            <CommandItemTemplate><asp:LinkButton ID="LinkButton2" runat="server" OnClientClick="addNewClick(); return false;"><img style="border:0px" alt="" src="../../DataEditing/Img/AddRecord.gif" />Add New</asp:LinkButton></CommandItemTemplate>

[Solved] RadTreeView in RadComboBox causes full (non-AJAX) Postback

I've embedded a RadTreeView in a RadComboBox much like the online example, except that I've added event handlers to the RadTreeView for the NodeClick event. I've also wrapped all of this in an AJAX Panel to avoid causing a full page post-back. But, it seems like the RadTreeView simply ignores this AJAX wrapper and causes a full page post-back anyway.

I've included a code sample:

    
            <%@ Page Language="C#" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <script runat="server"> 
        
                protected void TreeView_SelectedIndexChanged( object sender, EventArgs e ) 
        
                { 
        
                    RadTreeView rtv = (RadTreeView) sender; 
        
                    RadComboBoxItem item = CB1.SelectedItem; 
        
                    item.Text = rtv.SelectedNode.Text; 
        
                    item.Value = rtv.SelectedValue; 
        
                } 
        
                protected void ComboBox_SelectedIndexChanged( object sender, EventArgs e ) 
        
                { 
        
                    RadComboBox rcb = sender as RadComboBox; 
        
                    LIT1.Text = rcb.SelectedItem.Text; 
        
                } 
        
            </script> 
        
            <html xmlns="http://www.w3.org/1999/xhtml">

                            <telerik:RadComboBoxItem Text="Item 2" Value="2" /> 
        
                            <telerik:RadComboBoxItem Text="Item 3" Value="3" /> 
        
                        </Items> 
        
                    </telerik:RadComboBox> 
        
                    <asp:Literal ID="LIT1" runat="server">Item Value</asp:Literal> 
        
                </telerik:RadAjaxPanel> 
        
                </form> 
        
            </body> 
        
            </html>

I included the second RadComboBox just to show that the AJAX panel works for simpler controls.

[Solved] no preview in image browser for filename with symbols

i have an image with the following filename: "~_-box!@#$%^&().jpg"

in the image file manager from the radeditor, i am able to upload this file and see it in the list of files. i can select the file and get back the correct filename. but in the preview pane of the file manager, no image is displayed.

looking at the network traffic, the browser is asking for "~_-box!@".

is there any way to get the file manager to escape filenames?

[Solved] Custom combobox edit column template

Hi all,
i have a problem with my custom edit column template.

This is my column

                            { 
        
                                return this.box != null; 
        
                            } 
        
                        } 
        
                        public override string Text 
        
                        { 
        
                            get 
        
                            { 
        
                                if (this.box.SelectedItem == null) 
        
                                    return string.Empty; 
        
                                return this.box.SelectedValue; 
        
                            } 
        
                            set  
        
                            { 
        
                                this.box.SelectedIndex = string.IsNullOrEmpty(value) ? 0 :  
        
                                                       this.box.FindItemIndexByValue(value); 
        
                            } 
        
                        } 
        
                    }

All works fine, but when i edit an existing item, the selected item displayed on combobox is not the current value.

The SelectedIndex is correctly but the displayed item is always the first.

Any suggestion?

Thanks in advance,
Flavio

radspell - escape characters

Hi
I'd like to use the radspell feature but the trouble is that in French we have a lot of contractions with the apostrophe and the words with apostrophe are automatically underlined as wrong words, because the engine considers that there's only one word and not two (for instance, "l'immeuble" is the word "immeuble" with the article "l"). How could I say that I want the apostrophe to cut words ?

Horizontal Orientation to RadTreeView?

is there anway to use RadTreeView to create a horizontal orientation similar to the breadcrumb control shown at Some Other Control Site?

I want to use the treeview to provide an admin interface to modify the data that will be used to create the RadMenu for a site (think menu admin tool). Rather than a typical vertical tree, it would be nice to make it horizontal instead.

Thanks,
Rob

[Solved] Pager Template with Slider

Do you guys have any examples of incorporating a slider into a pager template? I know you have a slider setting for your standard pager, but i have a template in which I want to place the slider in between the back and forward buttons. My template looks fine of course, but needs to be wired to the pager navigation and I was hoping maybe you guys already had a sample of this.

Thanks!

Couple of image editing issues

During my implementation of the prometheus RadEditor, i noticed the following issues/bugs:

1. When resizing an image I uploaded and embedded in the body of the editor, I could not find a way to keep it proportional when dragging by the handles. Is there a way to do this? I was hoping there was something like photoshop has where holding the ctrl button while dragging keeps it proportional. I tried setting the image properties which have a "link" icon between the height/width that indicates that it should stay proportional, but it doesn't. I was expecting to plug in a width and it calculate the height, but it didnt. Any suggestions?

2. I was using the image editor within the image manager and tried to use the crop feature. I move the box around the section I wanted to crop to and saved it. But what happened is instead of cropping to the points I set (which were more in the center of the image) it cropped starting from the top left edge to the size I had set. Its as if it ignored its starting x/y position and only cropped based on the height/width of the box.

RadGrid gridbuttoncolumn event handling problem

Hi.

I have a RadGridButton column

<

telerik:GridButtonColumn CommandName="print" Text="Print" UniqueName="Print" ButtonType="PushButton">

</telerik:GridButtonColumn>

and in event handling of the Command I want to do this:

void

RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "print")

{

.
.
.
System.Diagnostics.Process.Start(Server.MapPath("App_data\\print.doc"));
}

Problem is that Word document won't open.

I put a test button on the same ASP page(outside of RadGrid) and handled Click event with calling to System.diagnostic.process.start as above. It works and opens Word document. So The question is: why RadGrid button cannot handle call to open word document?

Thank you in advance
