Hi,
I have a detailsview with a radcombobox in the emptytemplate. I want to validate this (I am using load on demand). It seems I need to validate via javascript, but can not get this to working with examples you gave in other forums. I want to prevent the users from typing in an incorrect code in the combo box - one that does not exist and pass validation. Here's what I tried:

    
                    function validateCombo(source, args)    
        
                    {    
        
                       args.IsValid = false;  
        
                       var elements = document.getElementsByTagName('*');  
        
                       var count = elements.length;  
        
                       var targetId = 'rcbCAGE';  
        
                       var i;  
        
                       for (i = 0; i < count; i++) {  
        
                            var element = elements[i];  
        
                            var pos = element.id.indexOf(targetId);  
        
                            if(pos >= 0 && element.type == 'text' ) {  
        
                                //found rad combo element  
        
                               var text = element.get_text();    
        
                               var item = element.findItemByText(text);    
        
                               if (item)    
        
                               {    
        
                                   args.IsValid = true;    
        
                               }    
        
                            }  
        
                    }

The line var text = element.get_test() throws an error that the method is not valid.

Here's a snippet of the HTML page:

    
                    <asp:DetailsView ID="dvCageCode" DataKeyNames="CageCodeID" runat="server" AutoGenerateRows="False" 
        
                        DataSourceID="CAGEData" Height="50px" Width="337px"   
        
                        OnItemCommand="dvCageCode_ItemCommand"   
        
                        OnItemCreated="dvCageCode_ItemCreated"   
        
                        ondatabound="dvCageCode_DataBound"   
        
                        onitemupdating="dvCageCode_ItemUpdating"   
        
                        oniteminserting="dvCageCode_ItemInserting"   
        
                        OnItemInserted="OnItemInserted"

                                        <asp:CustomValidator ID="cValCAGE"     
        
                                            runat="server"     
        
                                            ControlToValidate="rcbCAGE"    
        
                                            ValidateEmptyText="True"    
        
                                            ClientValidationFunction="validateCombo"    
        
                                            ErrorMessage="Please select a CAGE Code from the list">    
        
                                        </asp:CustomValidator>    
        
                                    </td> 
        
                                </tr> 
        
                            </table> 
        
                        </EmptyDataTemplate>

I am using Rad Controls for ASP.net ajax controls on asp.net 2.0
Assembly version = 2008.2.826.20
File Version = 2008.02.0826.20

When I host the site in local machine its works fine, but I get the above mentioned error when I upload it to production server. The production server has ASP.Net 3.5 though. I have also downloaded the specified dll files for 3.5 but that is also not working.

Please advice asap as we are working on a tight schedule.

Adding paging into Footer of grid?

Hi there,
Is it possible to add paging into the footer of a grid? The reason I ask is I have created a UI where I have my add and editing buttons sitting inside the CommandItemTemplate. I am wanting the paging to sit ontop of my CommandItemTemplate not below.

Currently if I add Paging="true" this displays below my CommandItemTemplate which is not my desired result.

Has anyone done this before or do I need to build some custom paging function?

Thanks
Shane

ExportToCsv of a Self-referencing hierarchy grid

Hello

Is there a way to export to CSV all the data in a self-referencing hierarchy grid?

I am using this command to export to CSV. But this only exports the data of the Parent.
RadGrid.MasterTableView.ExportToCSV();

I tried different solution in the forums but it is still not working. Any help on this matter?

Dynamic Content

If I have this in the ASPX

    
            <telerik:RadPanelBar ID="RadPanelBar1" runat="server" Skin="Outlook" Width="190px" ExpandMode="MultipleExpandedItems">   
        
              <CollapseAnimation Duration="100" Type="None" /> 
        
              <ExpandAnimation Duration="100" Type="None" /> 
        
            </telerik:RadPanelBar>

And I try to do this from C#

    
            var m1 = new RadPanelItem("item 1"); 
        
            m1.Items.Add(new RadPanelItem("sub1")); 
        
            m1.Items.Add(new RadPanelItem("sub2")); 
        
            m1.Items.Add(new RadPanelItem("sub3")); 
        
            RadPanelBar1.Items.Add(m1); 
        
            var m2 = new RadPanelItem("item 2"); 
        
            m2.Items.Add(new RadPanelItem("sub1")); 
        
            m2.Items.Add(new RadPanelItem("sub2")); 
        
            m2.Items.Add(new RadPanelItem("sub3")); 
        
            RadPanelBar1.Items.Add(m2);

It works fine, however when I try to add custom content rather than RadPanelItems like this:

    
            var m1_d = new RadPanelItem("item custom"); 
        
            m1_d.Controls.Add(new Label() { Text = "sub1", ID = "s1" }); 
        
            m1_d.Controls.Add(new Label() { Text = "sub2", ID = "s2" }); 
        
            m1_d.Controls.Add(new Label() { Text = "sub3", ID = "s3" }); 
        
            RadPanelBar1.Items.Add(m1_d);

while I see the results on the page when clicking on the header the panel bar would not collapse. From a quick look at the rendered HTML the rpExpandable CSS class is not applied in the later case (when adding labels) -- not sure if this makes a difference or not.

Thanks.

P.S. this behavior is not browser specific.

[Solved] Disable Filtering on specific columns with AutoGenerate columns

Hi,

I have created a CrossTab routine which populates a RadGrid. I always no there will be a "Project" column in the first column, but the rest are generated as crosstabs based on the date criteria.

I need to enable filtering on the Projet column, but remove it programatically from all other columns.

How do I do this?

I tried capturing the column in PreRender and looking for col.AllowFiltering but this doesnt appear to be an option?

Thanks

Reloading Nodes

Hi,
I'm using a TreeView with ExpandMode=ServerSideCallback and it's working fine. However, in certain situations I want to reload from a certain node (and all its children), without having to reload all the other nodes which were already loaded.
A situation for example where I might need it - a popup window was opened, where some data changes can be made. Once it is saved or closed, a client-side function in my page is called, and now I want to reload some data from the server which would update a relevant node (but again, without having to reload the whole tree).
How can I achieve this?

RadSlider in RadGrid PopUp

Hi,

I placed a couple of RadSliders to the RadGrid's popup edit window and now I have a problem with sliders when scrolling the popup's content. All the other content scrolls as they should but RadSlider does not scroll at all. Do I have to redraw radsliders somehow or what can I do to fix this one?

Thanks

[Solved] What is best technique for coordination Date Change event beteen client and server?

I am new to RAD controls, and have a very simple question about technique.

Previously, our Calendar form used the Calendar control that ships with VS2008.

We ran a VB server procedure to update the form.

I swapped-in the new RADCalendar control, and tried to do the minimal amount of work to get the form running.

I found that setting AutoPostback to "true", along with EnableViewState to "true", would send me back to the server, where I would read the selected date and rebuild the form.

Works fine, but defeats the advantages of a client control for browsing dates.

Still a novice in JavaScript, I think I should disable AutoPostback, trap the SelectedDate change event, then postback to update the page contents from the database.

This is probably 2-3 lines, but in a language where I am stuck on chapter one of JavaScript for Dummies - Slow Learner Edition.

Can somebody point me in the right direction? Thanks
