I added a progress bar on my page as shown in the code. But this page started giving me this error:Line: 1429
Error: Sys.ArgumentTypeException: Object of type 'Object' cannot be converted to type 'Array'.
Parameter name: array

This error is associated with script manager. Which ever page I put the script manager, it starts giving me the same error. Please help me to remove this error.

Onmouseover in Firefox (first level)

I'm using RadMenu like the "mega drop down" sample.

In IE, moving the mouse over the text of the first level menu fires the menu drop down, which is perfect. However, on Firefox and other browsers, the drop down fires only when moving the mouse over the bottom of the links.

I'm attaching a gif to explain it better.

How can I correct this, please ?

Make Tooltip bigger?

Hi

I am using the ajax radgrid version 2010.1.519.35 and displaying part of a long piece of text in a column. The complete text I display in the tooltip like so:

    
            protected void rgViews_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e) 
        
            { 
        
                  if (e.Item is Telerik.Web.UI.GridDataItem) 
        
                  { 
        
                        string fulltext = e.Item.Cells[3].Text; 
        
                        if (e.Item.Cells[3].Text.Length >= 70) 
        
                        { 
        
                              e.Item.Cells[3].Text = e.Item.Cells[3].Text.Substring(0, 70) + " ..."; 
        
                              e.Item.Cells[3].ToolTip = fulltext.Replace("\r\n", " ").Replace("\t", ""); 
        
                        } 
        
                  } 
        
            }

The tooltips displays fine in firefox 3.6.2, resizing to fit the data, - but the problem is in ie8 the tooltip size seems to max out at about 250px wide by 200px high, which truncates the data in the tooltip. Is there any way of making the tooltip bigger?

Kind Regards,
Jeremy

RadGrid doesn't do anything with RadToolBarButton

Hello,

I'm stuck here. I basically have RadToolBar to perform few functions on my RadGrid (such as Clear Filters, Export to Pdf, etc).

I handled the RadToolBarButton click events in the code behind like this:

                        Protected Sub RadToolBar1_ButtonClick(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadToolBarEventArgs) Handles RadToolBar1.ButtonClick         
                    If TypeOf e.Item Is RadToolBarButton Then         
                        Dim button As RadToolBarButton = TryCast(e.Item, RadToolBarButton)         
                     
                        If button.CommandName = "FullList" Then         
                            For Each column As GridColumn In RadGrid1.MasterTableView.Columns         
                                column.CurrentFilterFunction = GridKnownFunction.NoFilter         
                                column.CurrentFilterValue = String.Empty         
                            Next         
                            RadGrid1.MasterTableView.FilterExpression = String.Empty         
                            RadGrid1.MasterTableView.Rebind()         
                     
                        ElseIf button.CommandName = "ExportToPdf" Then         
                            RadGrid1.MasterTableView.ExportToPdf()         
                        End If         
                    End If         
                End Sub         

My aspx:

                       <telerik:RadToolBar runat="server" ID="RadToolBar1" OnButtonClick="RadToolBar1_ButtonClick" onclientButtonClicking="radToolBarClientClicked">         
                    <Items>         
                        <telerik:RadToolBarButton Text="Full List" CommandName="FullList" ImageUrl="~/Images/AwardsGrid/Table.gif"></telerik:RadToolBarButton>         
                        <telerik:RadToolBarButton Text="Print" CommandName="Print" ImageUrl="~/Images/AwardsGrid/Printer.gif"></telerik:RadToolBarButton>         
                        <telerik:RadToolBarButton Text="Export to Pdf" CommandName="ExportToPdf" ImageUrl="~/Images/AwardsGrid/Printer.gif"></telerik:RadToolBarButton>         
                    </Items>         
                </telerik:RadToolBar>         
                     
                <telerik:RadGrid ID="RadGrid1" runat="server" ShowStatusBar="true" GridLines="Both" CssClass="RadGridCustomClass" AllowFilteringByColumn="true" OnItemCommand="RadGrid1_ItemCommand" >          
                    <!-- my RadGrid contents -->         
                </telerik:RadGrid>         

Funny thing is when I debug, the event is captured. However after it finishes executing, nothing happens.. (filters are not cleared, no pdf exported) etc. Basically it does nothing.

However if I use normal buttons (not RadToolBar) like this:

                        <asp:LinkButton ID="LinkButton3" runat="server" type="button" Text="[ Export to Pdf ]"         
                    OnClick="LinkButton3_ButtonClick" Font-Underline="false" ForeColor="Black" />         

                        Protected Sub LinkButton3_ButtonClick(ByVal sender As Object, ByVal e As EventArgs) Handles LinkButton3.Click         
                    RadGrid1.MasterTableView.ExportToPdf()         
                End Sub         

I can get the pdf exported.

Any idea why and how to fix it?

One more thing, I tried clearing filters using client javascript :

                                function RefreshGrid() {         
                            var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();         
                            masterTable.filter("AwardID", "", Telerik.Web.UI.GridFilterFunction.StartsWith, true);         
                            masterTable.filter("AwardName", "", Telerik.Web.UI.GridFilterFunction.StartsWith, true);         
                        }         

It works, but the my current filter setting is gone. It becomes 'No Filter' . How do I persist my default filter?

Thanks!

Andreas

[Solved] How to change the title of the Delete popup window

Hi,

In my current project, on one of the web page I have a RadGrid with Add/Insert, Edit, Delete.

The web page is similar to as follows http://www.gouw.ws/RadGrid.aspx

When the Delete link on the RadGrid's row is clicked, a popup is displayed as follows http://www.gouw.ws/RadGridDelete.jpg

The title of the popup is "Message from webpage" instead of "Delete" as assigned to the ConfirmTitle on the ASPX.

Can you please tell me why this is so? How can I change the popup title to "Delete"?

The code of the web page is as follows:

ASPX

                    <form id="form1" runat="server">         
            <div>         
                <telerik:RadScriptManager ID="radScriptManager" runat="server" />         
                <telerik:RadGrid ID="radGrid" AutoGenerateColumns="false" AllowSorting="true" OnNeedDataSource="radGrid_NeedDataSource" runat="server">         
                    <ClientSettings>         
                        <Scrolling UseStaticHeaders="true" />         
                    </ClientSettings>          
                    <MasterTableView AllowMultiColumnSorting="true" CommandItemDisplay="Top" CommandItemSettings-AddNewRecordText="Add new founder" CommandItemSettings-ShowRefreshButton="false" EditMode="InPlace" TableLayout="Fixed">         
                        <Columns>         
                            <telerik:GridBoundColumn DataField="Name" DataType="System.String" HeaderText="Name" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" SortExpression="Name" AllowSorting="true" UniqueName="Name" />         
                            <telerik:GridBoundColumn DataField="Founder" DataType="System.String" HeaderText="Founder" HeaderStyle-HorizontalAlign="Left" ItemStyle-HorizontalAlign="Left" SortExpression="Founder" AllowSorting="true" UniqueName="Founder" />         
                            <telerik:GridEditCommandColumn ButtonType="ImageButton" HeaderStyle-Width="5%" UniqueName="Edit" />         
                            <telerik:GridButtonColumn ButtonType="ImageButton" ConfirmDialogType="RadWindow" HeaderStyle-Width="5%" ConfirmText="Delete this founder?" ConfirmTitle="Delete" CommandName="Delete" />         
                        </Columns>         
                    </MasterTableView>         
                </telerik:RadGrid>           
            </div>         
            </form>         

Regards,

Herman

Next/Prev Month Navigation Won't Work

Any time I specify to display more than one month (i.e.: multiple columns), the next and previous month navigation stops working. I don't even get a hover for the arrows on the right. I get a hover for the arrows on the left but clicking does nothing. This seems like a rather common thing to do. Does it not support this? If not why does it bother to show the arrows??

<telerik:RadCalendar ID="rcalStartDateRange" runat="server"

Skin="Office2007" ShowRowHeaders="False"

UseColumnHeadersAsSelectors="false" EnableMultiSelect="false" MultiViewColumns="2">

</telerik:RadCalendar>

Thanks in advance!
