Keeping track of checkbox state without postbacks

Hello,

I have a RadGrid with Paging enabled. On this grid, I have a GridClientSelectColumn. Currently, on Client Side, I am using Javascript to track which rows have been selected (so that if the user pages through the grid and returns to an earlier page, they will still see the checkboxes that they originally checked).

The issue that I am running into is, I need to also have a list of selected items for use on the server side. However, I do not want to perform a post back on the radgrid each time a row is selected or unselected.

Is there a way to do this without having to perform a post back, such as getting my object from javascript and throwing it into Server side somewhere?

Thanks,
Dave

Can the approach shown in the "Scheduler / Using RadToolTip" demo example be used with a RadScheduler control that is getting it's data using a WebService?

I've tried setting up the following:

    
                <asp:UpdatePanel runat="server" ID="UpdatePanel1" UpdateMode="Conditional"> 
        
                <ContentTemplate> 
        
                    <telerik:RadScheduler runat="server" ID="RadScheduler1" SelectedView="WeekView" SelectedDate="2009-02-02" 
        
                        TimeZoneOffset="03:00:00"  
        
                        StartEditingInAdvancedForm="false"  
        
                        EnableCustomAttributeEditing="false"  
        
                        OnClientAppointmentsPopulating="initRadScheduler" 
        
                        OnClientAppointmentsPopulated="appointmentsLoaded"  
        
                        OnClientAppointmentDataBound="appointmentDataBound"  
        
                        OnClientAppointmentMoveEnd="appointmentMoveEnd"  
        
                        OnClientAppointmentMoving="appointmentMoving"> 
        
                        <WebServiceSettings Path="SchedulerWebService.asmx" ResourcePopulationMode="ServerSide" /> 
        
                    </telerik:RadScheduler> 
        
                    <telerik:RadToolTipManager runat="server" ID="RadToolTipManager1" Width="320" Height="210" 
        
                        Animation="None"  
        
                        HideEvent="LeaveToolTip"  
        
                        Text="Loading..."  
        
                        RelativeTo="Element" 
        
                        OnAjaxUpdate="RadToolTipManager1_AjaxUpdate"  
        
                        OnClientBeforeShow="clientBeforeShow"/>        
        
                </ContentTemplate> 
        
                </asp:UpdatePanel>

But I never seem to get a call to RadToolTipManager1_AjaxUpdate.

Thanks,
Greg

Problems with detail table collapse and edit mode

Hi,

we've a grid with 3 levels. The second and third levels are set to edit mode in the prerender event of the grid.
The problem is, that it is possible to expand these levels. but collapsing doesn't work anymore?!

Here is the sample code:

    
            protected void RadGridContractProducts_PreRender(object sender, EventArgs e) 
        
            { 
        
                    for (int i = RadGridContractProducts.MasterTableView.GetItems(GridItemType.NestedView).Length - 1; i >= 0; i--) 
        
                        { 
        
                            for (int j = ((GridNestedViewItem)RadGridContractProducts.MasterTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews.Length - 1; j >= 0; j--) 
        
                            { 
        
                                SetItemsMode(((GridNestedViewItem)RadGridContractProducts.MasterTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews[j]); 
        
                            } 
        
                        } 
        
                        RadGridContractProducts.Rebind(); 
        
                    } 
        
            private void SetItemsMode(GridTableView oGridTableView) 
        
                    { 
        
                        for (int i = oGridTableView.Items.Count-1; i >= 0; i--) 
        
                        { 
        
                            oGridTableView.Items[i].Edit = true; 
        
                        } 
        
                        for ( int i = oGridTableView.GetItems(GridItemType.NestedView).Length -1; i >=0 ; i-- ) 
        
                        { 
        
                            for ( int j = ( ( GridNestedViewItem )oGridTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews.Length -1 ; j >=0; j--) 
        
                            { 
        
                                SetItemsMode(((GridNestedViewItem)oGridTableView.GetItems(GridItemType.NestedView)[i]).NestedTableViews[j]); 
        
                            } 
        
                        } 
        
                    }

Could someone explain how to get this problem solved?

Thanks in advance

Rad Scheduler: When do you bind data?

Hello,

I am running VQ3 2009 with hotfixes. I'm having trouble with databinding the scheduler.

I am binding the data in the server side code by querying my appointments table.
I traverse the datatable of appointments and build a generic list of <Appointment> objects.
I then set the datasource of thescheduler to the generic list.

I first put this code in the PageLoad() event, but though the data showed in the scheduler just fine, it seemed to cause issues with the navigation pane's calendar popup.

I then moved the code to the PageInit() event. I get unpredictable behavior now where sometimes when i open the page, the scheduler does not contain data, but when I refresh it finally shows the appointments.

Questions:
1. Where should I put my server side data binding statement?
2. Should it be wrapped in an "If(!IsPostBack)" call?

Thanks,

Ryan

CSS for Column Header Hover?

Hello,

My apologies if this is a simple question... I just couldn't seem to track it down. Is there a specific CSS value to allow for when the mouse is hovered over a column header? I want to change the column header background image when it is hovered over the specific column (something I've seen a lot of other grids do), but can't seem to find where to do that with the Telerik grid.

Thanks in advance!

Preventing appointment entry for dates in the past

I am implementing the RadScheduler to manage scheduling data from a Dynamics CRM system. One of the requirements is that the user not be able to enter an appointment for a date prior to 12 am for the current day. I have found the FormCreating server side event and can cancel the insert, however, I've not been able to figure out how to tell the user why the appointment isn't created. I'm a Winforms developer that has been asked to deal with this issue and I'll admit my javascript/aspx skills are rusty. I've seen plenty of examples where javascript is registered from code behind, but these are all associated with an OnClick event. I don't have a client side OnClientFormCreating that I can use to validate this on the client side.

Is there a native way to handle this through a property on the scheduler or how would I best achieve this? I'd love to be able to integrate RadWindow manager and use the alert dialog.

Thanks.
Chuck

How to edit control properties in insert and edit mode?

Hi,
I have a radupload tool in my RadGrid.
I allow user to upload file when user edits or inserts a row. But when inserting a row, I want user to be able to upload more than one files. On the other hand, when editing a row, I want user to insert just one file.
-This means I should be changing upload tool's property in edit and insert mode of grid-

Here is my grid:

    
            <MasterTableView Width="100%" CommandItemDisplay="Top"> 
        
                    <Columns> 
        
                        <telerik:GridEditCommandColumn></telerik:GridEditCommandColumn> 
        
                        <telerik:GridTemplateColumn UniqueName="File" HeaderText="Image File"> 
        
                             <ItemTemplate> 
        
                                <asp:Image ID="img" runat="server" Height="50px"/> 
        
                            </ItemTemplate> 
        
                            <EditItemTemplate> 
        
                                    <telerik:RadUpload ID="upload" runat="server" AllowedFileExtensions="gif,jpg,png" AllowedMimeTypes="image/gif,image/jpeg,image/png"></telerik:RadUpload> 
        
                            </EditItemTemplate> 
        
                        </telerik:GridTemplateColumn> 
        
                        <telerik:GridBoundColumn 
        
                            DataField="Title" 
        
                            HeaderText="Title" 
        
                            UniqueName="Title"> 
        
                        </telerik:GridBoundColumn> 
        
                  </Columns>         
        
            </MasterTableView>

How can I do that? I added this code below to ItemDataBound method. But it makes MaxFileInputCount=1000 in both edit and insert mode.
MaxFileInputCount should be 1 in edit mode and it should be 1000 in insert mode.

This is the code I wrote to ItemDataBound

    
            if (e.Item is GridEditableItem && e.Item.IsInEditMode && grid.MasterTableView.IsItemInserted) 
        
                        { 
        
                            GridEditableItem temp = e.Item as GridEditableItem; 
        
                            ((RadUpload)temp["File"].FindControl("upload")).MaxFileInputsCount = 1000; 
        
                            ((RadUpload)temp["File"].FindControl("upload")).InitialFileInputsCount = 1; 
        
                        }
