Hello,

I'm wondering if there is a way to add a new data without refreshing the grid. The problem I'm having is that whenever invoking showInsertItem(), it refreshes the entire form and that causes calling database again and again.

I looked for a property of MasterTableView to prevent the calls, but I couldn't find one.

The reason why it refreshes the entire page is probably because I'm binding data. Does it mean that if data is bound to RadGrid, refreshing is invevitable when inserting/updating/deleting a record?

Please let me know if there is any clue how to resolve this issue.

Thanks!

AutoCompleteType has no effect

The following AutoCompleteType settings have no effect:

    
            <telerik:RadTextBox ID="RadTextBox1" runat="server"    
        
                 EmptyMessage="Username"   
        
                 AutoCompleteType="None" 
        
            />   
        
            or 

                        <telerik:RadTextBox ID="RadTextBox1" runat="server"    
                    
                             EmptyMessage="Username"   
                    
                             AutoCompleteType="Email" 
                    
                        />

I've tested in both IE8 and FireFox 3.5. Both browsers have autocomplete enabled and regular TextBoxes work fine. Is there an additional setting that I'm missing? Thanks!

FilterMenu Clipping in Grid

Hello,
I am having a problem where the FilterMenu is clipping the right side and bottom of the filtermenu when it is displayed for a Date column. The FilterMenu displays correctly for all other columns until the Date column is selected and then it is displayed clipped for all columns.
We are limiting the available FilterFormatString to:
"NoFilter"
"Contains"
"StartsWith"
"GreaterThanOrEqualTo"
"LessThanOrEqualTo"
"IsEmpty"

[Solved] Question re: data transfer

I have a paginated radgrid that connects to a table with 23k records, of which I have 500 records displayed per page. Now, it takes a long time to get this first display, as I would expect for such a large DataSet. The problem is that it takes just as long to display another page of the radgrid, like it is going back to the database, refilling the DataSet, and then paging the data into the new display.

I am using the object source design pattern (simplified MVC), where (1) view (ASPX) requests data -> (2) controller (ASP .NET) invokes data access object -> (3) DAO queries database and stores DataSet as model in Application scope if it is not already present -> (4) controller delivers requested data to view

When radgrid needs another page of data, isn't that data readily available in the DataSet? Is the entire DataSet sent to the client (which is what I want) for quicker page transitions?

Relevant ASPX:

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="RadGrid1">  
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="block" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManager> 
        
            <telerik:RadGrid ID="radGrid1" runat="server">  
        
                <MasterTableView> 
        
                <Columns> 
        
                    <telerik:GridHyperLinkColumn DataTextField = "LIN" HeaderText = "LIN" DataNavigateUrlFields = "LIN" UniqueName = "lin"></telerik:GridHyperLinkColumn> 
        
                * * *  
        
                </Columns> 
        
                </MasterTableView> 
        
            </Telerik:RadGrid>

Relevant Codebehind:

    
            Protected Sub radGrid1_Load( sender As Object, e As EventArgs) Handles radGrid1.Load  
        
                Try  
        
                    If Application( "lins" ) Is Nothing Then  
        
                        Application( "lins" ) = dao_LIN.Get_LINs()  
        
                    End If  
        
                    radGrid1.DataSource = DirectCast( Application( "lins" ), DataSet )  
        
                    radGrid1.DataBind()  
        
                Catch ex As HttpException   
        
                    RadAjaxManager1.Alert( "Communication with the database failed: " & ex.Message())  
        
                    Response.Redirect( "/Lexis/Lexis_error.aspx?module=rcm" )  
        
                End Try  
        
            End Sub

The DAO (without exception code):

    
            <DataObject( True )> _  
        
            Public Class dao_LIN  
        
                <DataObjectMethod( DataObjectMethodType.Fill )> _  
        
                Public Shared Function Get_LINs() As DataSet  
        
                    Dim ds As DataSet = New DataSet()  
        
                    Dim cmd As OracleCommand = New OracleCommand( "select * from VW_LIN_REF_WITH_COSTS order by LIN", dao_Conn.Instance( "OracleConnectionString" ))  
        
                    Dim da As OracleDataAdapter = New OracleDataAdapter( cmd )  
        
                    da.Fill( ds )  
        
                    Return ds  
        
            End Function

Seems pretty straight-forward to me. What am I missing so that I can get the pagination on the client to be very fast?

Cheers!
Mark

a.Month is undefined

We're having an issue with a calendar implementation. When the user navigates to the page with the calendar on it, everything works fine. But after clicking the back button (to go to the previous page) and then clicking the forward button (to go back to the calendar page), all JavaScript on the calendar stops working. In the error console, I see the following error: "a.Month is undefined." Is anybody else having trouble with this? Is there a workaround?

Timeline View Height & Calendar

Hello,

As it is said by another user in this thread : http://www.telerik.com/community/forums/aspnet-ajax/scheduler/timeline-view-height.aspx
I am not able to fix the height of the scheduler in timeline view without feeding it with data. So, I cannot see the whole popup calendar to choose a specific date.

Do you know additionnal information on the corrective release date ?
Are there any workaround to get through this ? (I do not want to hide the timeline link)
