I just upgraded my Telerik.dll to 2008.3.1312.35 and my filter on enter seems to have quit working.

I have this code in the code-behind for the ItemCreated event:

    
                    If e.Item.ItemType = GridItemType.FilteringItem Then 
        
                        Dim filterItem As GridFilteringItem = e.Item 
        
                        For Each col As GridColumn In rgSelectCustNo.MasterTableView.RenderColumns 
        
                            If col.UniqueName = "ExpandColumn" Or col.UniqueName = "RowIndicator" Then 
        
                                Continue For 
        
                            Else 
        
                                Dim colName As String = col.UniqueName 
        
                                Dim txt As TextBox = CType(filterItem(colName).Controls(0), TextBox) 
        
                                If Not txt Is Nothing Then 
        
                                    txt.Attributes.Add("onkeypress", "filterOnEnter(this, event, '" & rgSelectCustNo.ClientID & "', '" & colName & "')") 
        
                                End If 
        
                            End If 
        
                        Next 
        
                    End If

And this javascript in the HTML:

    
                    var cancelFilterMenu = false; 
        
                    var tableView = null; 
        
                    function filterOnEnter(sender, e, gridId, col) { 
        
                        if (e.keyCode == 13) { 
        
                            cancelFilterMenu = true; 
        
                            if (tableView == null) { 
        
                                tableView = $find(gridId).get_masterTableView(); 
        
                            } 
        
                            var filter = Telerik.Web.UI.GridFilterFunction.Contains 
        
                            var query = sender.value; 
        
                            if (query.endsWith('*') && query.startsWith('*')) { 
        
                                filter = Telerik.Web.UI.GridFilterFunction.Contains; 
        
                                query = query.substr(1, query.length - 2); 
        
                            } else if (query.endsWith('*')) { 
        
                                filter = Telerik.Web.UI.GridFilterFunction.StartsWith; 
        
                                query = query.substr(0, query.length - 1); 
        
                        } 
        
                            tableView.filter(col, query, filter); 
        
                        } 
        
                    }

The application is still working on my development and production machine, but only because I have not upgraded the Telerik.dll yet. The web page with the above code has not been modified since deployment to both the development and production environments.

Thanks!

Hello mkasuboski,

The behavior you are experiencing is due to the introduction of Column's FilterTemplate functionality. Thus your custom code should be modified in order to function correctly with this grid feature. I have attached a sample page which demonstrates the necessary changes.

Also please note that there was an issue with client-side filter function, which was addressed by our developers. That is why the archive contains a trial version of the latest internal build (you may open a formal support ticket for the dev version or check when it is available in latest internal build section of your account).

We updated your Telerik points for drawing our attention to these details.

Okay, I only saw one difference in your attached code sample and my current code sample, and I don't see how this will fix the issue.
The difference is only 1 line in the client side code in the filterOnEnter function.

Here is my line of code:

    
            tableView.filter(col, query, filter);

Here is your line of code from the attached sample:

    
            tableView.filter(col,query,1);

All you did was hard code a filter option, instead of letting the prior code in the function determine the filter option. I really don't see how this will correct the issue I am having.

In the rest of your email, are you telling me that there is a newer version (trial) of the DLL that WILL fix my issue, or that it addressed client side filtering issue and you really don't know if it will fix the issue?
What version is this new DLL, and what code changes will I need to make when using this new DLL?

Hi mkasuboski,

I'm sorry about the confusion.

The actual line that need to be changed is this:

    
            txt.Attributes("onkeydown") = "filterOnEnter(this, event, '" & RadGrid1.ClientID & "', '" & colName & "')"

This will override the onkeydown function which is added to the textbox control.

As to the mentioned version of the dll (attached previously):
It addresses the client-side filtering function issue which will throw a js error if a Telerik.Web.UI.GridFilterFunction enum value if passed instead of an GridFilterFunction's string representation.
