radConfirm for dynamically generated buttons

Probably a shameful noob question: I'm generating a series of buttons on page load from a SQL datasource using XSL. I'm having an issue with radConfirm and the postback. My confirm dialog shows up, but clicking OK doesn't trigger the underlying Command.

    
            <asp:ImageButton ID="b_RemoveMod_{@mID}" runat="server" 

                 ImageUrl="~\Images\12.png" AlternateText="Remove Module" CssClass="hideMe" 

                 CommandName="RemoveModule" 

                 CommandArgument="{@mID}" 

                 OnCommand="ImageButton_onCommand" 

                 onClientClick="radconfirm('Are you sure you want to delete the module and return it to inventory?', 

                      confirmRemoveMod, 300, 140, null, 'Confirm Module Removal');" />

I'm not sure what the first parameter of the __doPostBack should be (and heck, I'm not that confident in the second parameter, neither). If it were always a single button, I suspect the first parameter would be something like <%= Button.ClientID %>. But how do I get the ID of the clicked image button when I don't know it's ID ahead of time? There could be one, there could be 20.

    
            function confirmRemoveMod(arg) { 
        
                 if (arg == true) { 
        
                      __doPostBack('', 'ImageButton_onCommand#RemoveModule'); 
        
                 } 
        
            }

Confirm dialog on insert/update in RADGrid Hierarchy

Hello Team,

I need to provide a Confirm dialog to proceed by check some validations of Parent and Detail table controls.

1. How do I get the values of Child edit form control on client side?
2. I have written onclientclick event on update button, but the post back happens though it returns false.... I had set causes validation property to true?
3. Finally I am planning to write on server side validation to check for parent item value and detail table edit form control. Which event needs to be handled in this case. I shud show confirm dialog on validation. How do I achieve this?

Please provide me pointers.

How to find if a Control is RadComboBox

Hi,

We have a base page where we need to traverse through all controls on the current page instance and set them to ReadOnly mode.
This works fine for most of the controls but does not work for RadComboBox. Process never gets into if (cntrl is RadComboBox) clause. Here is the function:

    
                   private void SetControlReadOnly(Control cntrl) 
        
                    { 
        
                        if (cntrl.HasControls()) 
        
                        { 
        
                            foreach (Control nestedContrl in cntrl.Controls) 
        
                            { 
        
                                SetControlReadOnly(nestedContrl); 
        
                            } 
        
                        } 
        
                        else 
        
                        { 
        
                            if (cntrl is RadComboBox) 
        
                            { 
        
                                RadComboBox ddl = (RadComboBox)cntrl; 
        
                                ddl.Enabled = false; 
        
                            } 
        
                            else if (cntrl is RadInputControl) 
        
                            { 
        
                                SetRadInputControlReadOnly((RadInputControl)cntrl); 
        
                            } 
        
                            else if (cntrl is CheckBox) 
        
                            { 
        
                                CheckBox chk = ((CheckBox)cntrl); 
        
                                chk.Enabled = false; 
        
                            } 
        
                            else if (cntrl is TextBox) 
        
                            { 
        
                                TextBox txt = ((TextBox)cntrl); 
        
                                txt.Enabled = true; 
        
                                txt.ReadOnly = true; 
        
                                txt.ForeColor = System.Drawing.Color.Black; 
        
                            } 
        
                        } 
        
                    } 
        
                    private void SetRadInputControlReadOnly(RadInputControl input) 
        
                    { 
        
                        input.Enabled = true;

Listview and skins issue

Hi All,
I was having problems with RadListView and RadFormDecorator (standard skins) (version 2009.3.1208.35)
What happened was that alignment and background was not as expected.
When I started on this post I wanted to include markup that would show the issue, but instead I stumbled upon a setting that works in this case.

The soulution was to have RadFormDecorator skip fieldsets, the markup then looks like this.

    
                <telerik:radformdecorator id="FormDecorator1" runat="server" DecoratedControls="all" ControlsToSkip="Fieldset"  Enabled="true" > 
        
                </telerik:radformdecorator>

The skin selection is in the web.config file.

Hope this can help someone else, since it had me puzzled for hours.

[Solved] Column Maximum Length

Hi is there a way to apply a kind of MaxLength on a GridBoundColumn?

Lest assume you have a very long text like this one

Andrew_received_his_BTS_commercial_in_1974_and_a_Ph_D__in_international_marketing_from_the_University_of_Dallas_in_1981___He_is_fluent_in_French_and_Italian_and_reads_German___He_joined_the_company_as_a_sales_representative,_was_promoted_to_sales_manager_in_January_1992_and_to_vice_president_of_sales_in_March_1993___Andrew_is_a_member_of_the_Sales_Management_Roundtable,_the_Seattle_Chamber_of_Commerce,_and_the_Pacific_Rim_Importers_Association_

Go to http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/usercontroleditform/defaultcs.aspx
Edit any row.
Paste the text above in the text fields and then click update.

How can we avoid displaying such long lines and breaking the grid?
Is there any mechanism that will display the first x characters followed by ...

ie : Andrew_received_his ...

thanks

Pierre
