refreshScheduler javascript error

I followed the example code to replace the edit form in the documentation. It all works fine except that I cannot get the scheduler to refresh after the radwindow closes.

I added an alert to the given javascript function:

function refreshScheduler()
{

    alert('about to refresh scheduler');
    var ajaxManager = $find("RadAjaxManager1");
    ajaxManager.AjaxRequest('RebindScheduler');
}

The alert displays but immediately afterward there is an "Error on page". Detail is "Object doesn't support this property or method.". The AjaxRequest event of the radAjaxManager never fires so the scheduler does not refresh.

Any ideas?
John.

using Grid Control dynamically

Hi guys,

First of all, I need to say something about the documentation... I'm trying to fix a web application where the guy that left the company made, using Telerik (because he was confortable with it) and it did all in several files without any comments... So I'm always lost, and your documentation does not help me a bit! :(

I miss the "Related to" and the functions and methods when using the Grid dynamically... we have the setup in a XML that is changed using a Windows Form, and this web application has to "read" that XML and create the design made, so... I can't write anything into the aspx file except a couple of tags that server as an anchor.

Your documentation lacks (a lot) about using the Controls dynamically, so, make calls on runtime, create actions, use the events, etc...

for example... I have in his code something like:

if (masterTable.get_isItemInserted() == true) {

__doPostBack('grid$ctl00$ctl02$ctl02$PerformInsertButton', '');

}

I wonder... where's the PerformInsertButton comes from? there is no reference at all in the code, and In some examples I can see that's something from the Grid Control.

Is there any tutorial, Documentation, anything (money is not a problem, I can schedule and buy a couple hours of Telerik Support), to get the know how of ALL functions and events (and descriptivly what do they do) of the Telerik controls, more specifically, the Ajax Controls?

Thank you...

Any new chart types / features coming for 2009?

Hi,

We are currently using Dundas (which we hate) for charting. I'm seriously considering migrating our project to Telerik charts since we already use Telerik for other stuff and was wondering if any new chart types / features were coming up that would help me justify the switch?

RadToolTipManager & RadDatePicker?

Hi All!

I used RadToolTipManager on my aspx page:

    
            <telerik:RadToolTipManager ID="ttEditSeason" runat="server" ManualClose="True" OnAjaxUpdate="ttEditSeason_AjaxUpdate" Position="TopRight" RelativeTo="Element" ShowEvent="OnClick" Width="950px" Height="200px" Skin="Web20"> 
        
            </telerik:RadToolTipManager>

and his AjaxUpdate event

    
            protected void ttEditSeason_AjaxUpdate(object sender, Telerik.Web.UI.ToolTipUpdateEventArgs e) 
        
            { 
        
                    Control ctrl = Page.LoadControl("~/user/EditSeason.ascx"); 
        
                    e.UpdatePanel.ContentTemplateContainer.Controls.Add(ctrl); 
        
            }

So, I load my user control in ToolTip (I get it from example http://demos.telerik.com/aspnet-ajax/tooltip/examples/loadondemand/defaultcs.aspx).
In my user control exist RadDatePicker. But when I click on DatePopupButton then popup calendar displaying under tooltip area. Why?

It code from my user control ascx page:

    
                                            <telerik:RadDatePicker ID="dpBeginDate" runat="server" Width="150px" Skin="WebBlue" Culture="English (United States)" EnableTyping="False" AutoPostBack="True"> 
        
                                                <DateInput LabelCssClass="riLabel radLabelCss_WebBlue" Skin="WebBlue" ReadOnly="True" Width="" AutoPostBack="True"> 
        
                                                </DateInput> 
        
                                                <Calendar Skin="WebBlue" UseColumnHeadersAsSelectors="False" UseRowHeadersAsSelectors="False" 
        
                                                    ViewSelectorText="x"> 
        
                                                </Calendar> 
        
                                                <DatePopupButton CssClass="radPopupImage_WebBlue" HoverImageUrl="~/Images/DatePicker.png" ImageUrl="~/Images/DatePicker.png" /> 
        
                                            </telerik:RadDatePicker> 
        
                                        </td> 
        
                                        <td> 
        
                                            <telerik:RadDatePicker ID="dpEndDate" runat="server" Width="150px" Skin="WebBlue" Culture="English (United States)" EnableTyping="False"> 
        
                                                <DateInput LabelCssClass="radLabelCss_WebBlue" Skin="WebBlue" ReadOnly="True" Width=""> 
        
                                                </DateInput> 
        
                                                <Calendar Skin="WebBlue" UseColumnHeadersAsSelectors="False" UseRowHeadersAsSelectors="False" 
        
                                                    ViewSelectorText="x"> 
        
                                                </Calendar> 
        
                                                <DatePopupButton CssClass="radPopupImage_WebBlue" HoverImageUrl="~/Images/DatePicker.png" ImageUrl="~/Images/DatePicker.png" /> 
        
                                            </telerik:RadDatePicker> 
        
            <br /> 
        
            <asp:Button id="btn" runat="server" text="Ok" />

Any ideas?

Thanks!

[Solved] Batch Updates and Null Values

Hi,

I am using the Batch Update method as found in the help files as follows:

    
            Hashtable newValues = new Hashtable(); 
        
                            //The GridTableView will fill the values from all editable columns in the hash 
        
                            e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem); 
        
                            //sqlUpdatePayments.UpdateCommand = String.Format("Update Customers SET ContactName='{0}' WHERE CustomerID='{1}'", newValues["ContactName"], editedItem.GetDataKeyValue("CustomerID").ToString()); 
        
                            sqlUpdatePayments.UpdateCommand = String.Format("UPDATE [MainBookings] SET [PaidType] = '{0}' WHERE [ClassBookedID] = '{1}'", newValues["PaidType"].ToString(), editedItem.GetDataKeyValue("ClassBookedID").ToString()); 
        
                            sqlUpdatePayments.Update();

When performing the update, the update fails when it encounters a Null value. (Not all the records always need a value)
The data in question is coming from the below BoundColumn,

<telerik:GridBoundColumn UniqueName="PaidType" DataType="System.String" ConvertEmptyStringToNull="true" HeaderText="PaidType" DataField="PaidType" />

Could someone advise how I can deal with these null values?

Thanks in advance.
Harry
