Labels for expanding nested view

I am using nested view templates. To expand into the nested view, user needs to click the arrow image on the row's left. Is there a way to put some labels to make the template opening action more explicit? Can the left-most column with the clickable arrow have a header, like other columns in the grid, where I could put text "Details"?

Also, can I replace the tooltip of the expand bottom? I'd like to put there "Click to see more details...".

If I can do the above, I will have to introduce a hyperlink column with text "Details" to open the nested view programmatically upon clicking the link. Is that possible?

Javascript error when using Radtabstrip and multipage

Hi,
I'm working with the Radtabstrip and multipage controls in 2010 release. I get an AJAX related javascript error when I click on any other tab (other than the active one) and it tries to make an AJAX callback. The error is:
i.get_postBackElement() is undefined
on the line:
if(Array.contains(c,i.get_postBackElement().id)){this._isRequestInProgress=true;

I've already tried compilation debug="false" in web.config and Scriptmode="release" on the scriptmanager. Any help will be appreciated.

Displaying error message on typing a invalid character

Hi,

I have a requirement like, I should accept any string which does not contain some special characters like @,*,& etc. Actually i should block the user from typing these character.
Similar behavior as the unit price text box in this example
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/alleditablecolumns/defaultcs.aspx.

At the same time i should display some error message to the user about the blocking action. I am bit confused of acheiving this through radinputmanager and a asp text area control.

I tried setting the telerik:RegExpTextBoxSetting tag with the right regular expression, validation message and the control id, but the validation happens only on click of any button.
This is the link i used as reference http://www.telerik.com/help/aspnet-ajax/using_radinputmanager.html

Kindly help me with some code snippets.

Regards,
Saravanan K

Too many items for Javascript to handle in a Callback

I'm using the following demo to load Combo items from a DB which I don't have linked to an Entity model (so old command query).

    
                [WebMethod(CacheDuration = 0)] 
        
                public RadComboBoxItemData[] LoadMedportalUsers(RadComboBoxContext context) { 
        
                    IDictionary<string, object> contextDictionary = (IDictionary<string, object>)context; 
        
                    string filterString = ((string)contextDictionary["FilterString"]).ToLower(); 
        
                    SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["myDB"].ConnectionString); 
        
                    SqlCommand selectCommand = new SqlCommand(@" SELECT UserID, UserName FROM Aspnet_Users
        
                                                                 WHERE LOWER(UserName) LIKE '%" + filterString + "%'", connection); 
        
                    SqlDataAdapter adapter = new SqlDataAdapter(selectCommand); 
        
                    DataTable users = new DataTable(); 
        
                    adapter.Fill(users); 
        
                    List<RadComboBoxItemData> result = new List<RadComboBoxItemData>(users.Rows.Count); 
        
                    foreach (DataRow row in users.Rows) { 
        
                        RadComboBoxItemData itemData = new RadComboBoxItemData(); 
        
                        itemData.Text = row["UserName"].ToString(); 
        
                        itemData.Value = row["UserID"].ToString(); 
        
                        result.Add(itemData); 
        
                    } 
        
                    return result.ToArray(); 
        
                }

We have about 3000 users in the AspNet_Users table...so this throws:
Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Is there perhaps a way to tweak to allow the dynamic loading?

Any way around that?

Not able to Find a control in the itemtemplate of the listbox

Hi,

I am trying to set a controls value, based on values sent from one listbox to the other. I have set up code to find the control in the ontransferred event of the listboxes. Currently I am using the findcontrol method of listbox that the item is being sent to, then I try to find the control by the ID. When the code runs though the control is being set to a null value instead of the control in the listbox.

Thanks,
jonathan

RadScriptManager Error

I'm having issues running RadScriptManager on a page that's uisng the RadGridView. If I use the regular ScriptManager I get javascript errors and the GridView does not let you select rows. If I switch to the RadGridView I get this:

RadTreeView DIsplay look

I have a web page using the RadTreeView and it has some data. I have a add and Edit button to edit the contents of the tree.

This all works fine with IE and firefox.

With safari, when I click the buton, the tree look changes. Instead of the + icon, I get dot icon. It all works but the look gets distorted. (the tree node changes from + to .)
