InstanceOrSeriesModalPopupExtender location

When the InstanceOrSeriesModalPopupExtender pops up, it's centered on the scheduler. Once one of the two options 'edit this occurrence' or 'edit the series' is selected, the Edit appt model popup is at the top of the page, and the page was scrolled to the top. How to I get the first popup to be in the same location?

[Solved] Display Loading Panel during Export

When the user clicks the Export Button, I want an ajax loading panel to display over the Panel. Then, when the export is complete I'd like the loading panel to close.

Using the OnAjaxRequestStart I am able to fire the loading panel. For the export to work, I have to set the EnableAjax = false. The problem is that when that is set, the OnResponseEnd is never fired.

Here's what I have so far. Any help would be appreciated:

    
            //Script    
        
              <script type="text/javascript">  
        
                    var currentLoadingPanel = null;  
        
                    var currentUpdatedControl = null;  
        
                    function RequestStart(sender, args) {  
        
                        currentLoadingPanel = $find("RadAjaxLoadingPanel1");  
        
                        switch (args.get_eventTarget()) {  
        
                            case "btnExcel":  
        
                            case "btnWord":  
        
                            case "btnCSV":  
        
                                //Disable Ajax  
        
                                args.EnableAjax = false;  
        
                                currentUpdatedControl = "Panel1";  
        
                                //show the loading panel over the updated control  
        
                                currentLoadingPanel.show(currentUpdatedControl);  
        
                                break;  
        
                        }  
        
                    }  
        
                    function ResponseEnd() {  
        
                        //hide the loading panel and clean up the global variables  
        
                        if (currentLoadingPanel != null)  
        
                            currentLoadingPanel.hide(currentUpdatedControl);  
        
                        currentUpdatedControl = null;  
        
                        currentLoadingPanel = null;  
        
                    }  
        
               </script>  
        
            //RadAjaxManager Configuration  
        
                <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

Form Decorator / Skin Style?

First off, let me say that Telerik kicks ass! Way easier to use than Infragistics. I gave up on trying to find the right videos for learning and used code from the demos.

The best way to explain my problem, look at this page. Mouse over text box and see that the border shows green. I want it to be red. I am not a design/layout/graphics/make-pretty expert. Where is the style/file/property to change green to red?

Thanks,

[Solved] GridButtonColumn, RadWindow and ConfirmText

I am databinding a RadGrid using the NeedDataSource event and my grid has a column configured as such:

<telerik:GridButtonColumn ButtonType="PushButton" CommandName="Delete" Text="Delete" ItemStyle-Width="20px" ConfirmDialogType="RadWindow" ConfirmText="Are you sure you wish to remove this item?<br /><br /><strong>This action is not reversible.</strong>" ConfirmTitle="Confirm Removal" />

There is a RadWindow on the page so the confirmation dialog looks better than the default one. The issue I have is wanting to set the ConfirmText on ItemDataBound (or a similar method) so I can do something like "Are you sure you wish to remove this item which will also remove 35 child items?" where 35 is a count done on the DataItem being used. I've tried searching the forums here and also reading through the API and, while plenty of things give me TableCell access or access to the button being generated, I see nowhere that I can modify this text on a row-by-row basis.

Any suggestions?

RadFilter - error on PostPack "Specified argument was out of the range of valid values"

Hi,

I am trying to use the RadFilter to create a customer filter. The code is as follows:

    
            <%
@ Control Language="vb" AutoEventWireup="false" CodeBehind="ReportCriteria.ascx.vb" Inherits="xxx.ReportCriteria" %>
            
<%
@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
            
<telerik:RadFilter runat="server" ID="RadFilter1" 
        
                    OnApplyExpressions="RadFilter1_ApplyExpressions">  
        
                        <FieldEditors> 
        
                            <telerik:RadFilterBooleanFieldEditor FieldName="Some Bool" /> 
        
                            <telerik:RadFilterTextFieldEditor FieldName="Some Text" /> 
        
                        </FieldEditors> 
        
                    </telerik:RadFilter>

and the code behind is...

    
            Imports Telerik.Web.UI  
        
            Partial Public Class ReportCriteria  
        
                Inherits System.Web.UI.UserControl  
        
                Protected Sub RadFilter1_ApplyExpressions(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadFilterApplyExpressionsEventArgs)  
        
                    Dim provider As New RadFilterSqlQueryProvider()  
        
                    provider.ProcessGroup(e.ExpressionRoot)  
        
                    ltlDebug.Text = provider.Result  
        
                End Sub 
        
            End Class

The filter displays correctly, and I can add criteria. However, as soon as I change the condition from 'Some Bool' to 'Some Text' I get the following error:

Specified argument was out of the range of valid values.
Parameter name: HierarchicalIndex


            [ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: HierarchicalIndex]
   Telerik.Web.UI.RadFilterItemsCollection.get_Item(String hierarchicalIndex) +63
   Telerik.Web.UI.RadFilter.HandleClientCommand(String commandName, String commandArgs) +505
   Telerik.Web.UI.RadFilter.RaisePostBackEvent(String eventArgument) +82
   System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13
   System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

Any ideas?

Thanks.

RadGrid, ObjectDataSource and Parameters

Hey there,

I've got a RadGrid bound to an objectDataSource but I've been running into an odd situation, on my grid I got the following declared:

    
            <telerik:GridDropDownColumn DataField="Continent.Id" HeaderText="Continente" DataSourceID="odsContinent" ListTextField="Name" ListValueField="Id" UniqueName="Continent" SortExpression="Continent" />

The problem is, regardless of the params I set on my objectDataSource I am not able to switch the param name from Continent.Id to something I could name a parameter on C# Code, so I always end up with the following error when trying to update an item:

"Sys.WebForms.PageRequestManagerServerErrorException: ObjectDataSource 'odsCountry' could not find a non-generic method 'GridUpdate' that has parameters: Alias, Fullname, Capital, Continent.Id, ThreeDigitCountryCode, ThreeLetterCountryCode, TwoLetterCountryCode, Id."

    
            <asp:ObjectDataSource ID="odsCountry" runat="server" 
        
                        TypeName="Highland.Models.Country"

                        StartRowIndexParameterName="firstResult" 
        
                        MaximumRowsParameterName="maxResults" >

                            <asp:Parameter Name="Id" Type="Int32" /> 
        
                        </DeleteParameters>

                            <asp:Parameter Name="Fullname" Type="String" /> 
        
                            <asp:Parameter Name="Capital" Type="String" /> 
        
                            <asp:Parameter Name="Continent" Type="String" /> 
        
                            <asp:Parameter Name="ThreeDigitCountryCode" Type="Int32" /> 
        
                            <asp:Parameter Name="ThreeLetterCountryCode" Type="String" /> 
        
                            <asp:Parameter Name="TwoLetterCountryCode" Type="String" /> 
        
                        </UpdateParameters> 
        
                        <InsertParameters> 
        
                            <asp:Parameter Name="Id" Type="Int32" /> 
        
                        </InsertParameters> 
        
                    </asp:ObjectDataSource>
