Continous Month display

Hi,

I am using the RADChart for simple bar graph. The data what I will be having will be

Month Count

Jan 213

Feb 345

May 344

Jul 102

Aug 123

I am binding the data in the code behind using

RadChart1.Series[0].DataYColumn = "Count";

RadChart1.PlotArea.XAxis.DataLabelsColumn = "Month";

RadChart1.DataBind();

So is there any way to confiure the chart to display the missing months. The value of course for those will be zero. But is there a way to display all the months from Jan to Dec?

Grid takes 8 sec. time to load the data

Hello,

I have a grid which takes 8 seconds to load the data and the same time to do all events. I checked the database stored procedure. But it takes less than a second. Can you please help me to improve the performance.

I am using RAD controls Q4 2006.

I am getting about 800 records with around 55 columns in each record. Out of 55 only 8 columns are visible in the grid but in edit mode all other columns are visible (only 5 are editable rest are disabled). I am using RadAjaxManager to show loading image.

My Radgrid syntax is as shown below:

<telerik:RadGrid ID="RadGrid1" OnNeedDataSource="RadGrid1_NeedDataSource" runat="server" AllowPaging="True" EditItemStyle-Wrap="true"

AllowSorting="True" AutoGenerateColumns="False" AllowAutomaticUpdates="True"

OnItemDataBound="RadGrid1_ItemDataBound" EnableLinqExpressions="false" OnItemCreated="RadGrid1_ItemCreated">

temptxtbox.BackColor = Color.LightCyan;

}

combobox = (DropDownList)item["q15a_coded"].Controls[0];

combobox.BackColor = Color.LightCyan;

}

I also tried using the trial version of the latest controls but the performance is the same.

Any help will be appreciated.

Thank you,

Load On Demand Tab/MultiPage

Hi,
I have a website with approx 30 pages that I want to load into RadPageViews in a RadMultiPage and select with a RadTabStrip. It would take a long time to load all the PageViews when the site is first loaded (several minutes) so I want to do it 'on demand'. I am using your "Load on Demand" example, except changing the PageViewCreated() to set the .ContentUrl of the PageView to the .aspx of my desired page instead of .Add the UserControl. I create all the Tabs in the PageLoad of the main page and add in the PageViews as each Tab is selected. All seems to work fine except once a PageView is created it gets reloaded every PostBack. I have the java code to stop postbacks when clicking a Tab that already has a PageView but, when you select a 'new' Tab this creates a postback and any already created PageViews appear to be 're-created'. For example, I create one PageView on startup and get the PageViewCreated() event as expected, where I set it's .ContentUrl to Describe.aspx and the PageLoad in Describe.aspx.cs is called. Then I select the next Tab and immediately get a PageViewCreated() for the first PageView and the PageLoad in Describe.aspx.cs is called again and 'IsPostBack' is false, and then I get the TabClick event where I add the next PageView and so on. By the time I've gone to 5 or 6 Tabs all previously created PageViews have to get reloaded each time a new Tab is selected and everything just goes too slow. Is what I'm attempting possible? We were doing the same thing using TabContainers and IFrames and were able to get it to do what we needed but I want to use the Telerik stuff...
Sorry for the long explanation.

Clientside Method Request

Could you guys plop in the ability to for us to check if a callback is already in progress with the panel? I'm always having to manually set and release locks...

I see there's an isUpdating already, but it's always returning false for me...
I'd like to just be able to do this

if(_menuHttpPanel.isProcessing == false){

_menuHttpPanel.set_value(_menuSearchBox.get_value());

}

RAD ToolTip Help on Image Hotspots

Hi,

I want to create a webpage which contains an imagemap with hotspots. On mouse move over the hotspots I want to display a tool tip, not just the alt.Text, but rather more information with another image and some text. I was following the RadToolTip demo (First Look) and adapted the same method to create this. But it is not working. I am attaching the code (only two web pages). Please some one take a look and tell me what I am doing wrong. The tool tip information is not pulled from any database but generated in the codebehind file based on the ID of the hotspot.

Since I spend almost a week playing with it with out any luck, any help is greately appreciated,
Thanks
Joe

How to acces my controls in customized advanced template from AppointmentInsert/Update EventArgs

At the moment i can access the controls already in my advanced customized template. I use the following code to do that:

protected void RadScheduler1_AppointmentCommand(object sender, AppointmentCommandEventArgs e)

{

Appointment appHuidig = e.Container.Appointment;

RadScheduler scheduler = (RadScheduler)sender;

RadDatePicker StartDate = (RadDatePicker)e.Container.Controls[1].FindControl("StartDate");

RadTimePicker StartTime = (RadTimePicker)e.Container.Controls[1].FindControl("StartTime");

RadDatePicker EndDate = (RadDatePicker)e.Container.Controls[1].FindControl("EndDate");

RadTimePicker EndTime = (RadTimePicker)e.Container.Controls[1].FindControl("EndTime");

RadComboBox rcb_AfspraakType = (RadComboBox)e.Container.Controls[1].FindControl("rcb_AfspraakType");

RadTextBox SubjectText = (RadTextBox)e.Container.Controls[1].FindControl("SubjectText");

RadTextBox DescriptionText = (RadTextBox)e.Container.Controls[1].FindControl("DescriptionText");

RadComboBox rcb_Adviseurs = (RadComboBox)e.Container.Controls[1].FindControl("rcb_Adviseurs");

int fiat = 1;

RadComboBox rcb_Kamers = (RadComboBox)e.Container.Controls[1].FindControl("rcb_Kamers");

CheckBox AllDayEvent = (CheckBox)e.Container.Controls[1].FindControl("AllDayEvent");

RadTextBox rtb_ProspectID = (RadTextBox)e.Container.Controls[1].FindControl("rtb_ProspectID");

However, i also do have validation on the server side, but when i want to cancel the update and leave the advanced form template open I have a problem, since the AppointmentCommandEventArgs doesnt have a cancel option. Besides this problem, I also want to implement drag and drop, however with drag and dropping i cannot access the Appointmentcommand as well.

So i want to move the update/insert from the appointmentcommand to the updatecommand/insertcommand:

protected void RadScheduler1_AppointmentInsert(object sender, Telerik.Web.UI.AppointmentInsertEventArgs e)

{

}

protected void RadScheduler1_AppointmentUpdate(object sender, Telerik.Web.UI.AppointmentUpdateEventArgs e)

{

}

But from these e's i cannot access the cs_advancedform, how can i achieve this, so i can easely access my controls on my customized advanced form template?

FilterTemplate filter value remains "All"

http://www.telerik.com/help/aspnet-ajax/radgrid-filter-template.html
The first time run it's correctly displaying "All", after I select a different dropdown item, the grid filters correctly, but the FilterDropDown still indicates "All". How do I make it display the value that was selected?

Update: It works now after I change it to use the client side version of example:

OnClientSelectedIndexChanged="TitleIndexChanged" SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Application").CurrentFilterValue %>'

The Server side still has the issue:

    
                                <FilterTemplate> 
        
                                    <telerik:RadComboBox runat="server" ID="FilterCombo" DataSourceID="srcApplication" AppendDataBoundItems="true" 
        
                                    DataValueField="Application" DataTextField="Application" AutoPostBack="true" 

                                    SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Application").CurrentFilterValue %>'

                                    OnSelectedIndexChanged="FilterCombo_SelectedIndexChanged"> 
        
                                        <Items> 
        
                                            <telerik:RadComboBoxItem Text="All" /> 
        
                                        </Items>                         
        
                                    </telerik:RadComboBox>            
        
                                </FilterTemplate>                     
        
                            </telerik:GridBoundColumn>

    
                Protected Sub FilterCombo_SelectedIndexChanged(ByVal o As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs) 
        
                    Dim filterExpression As String 
        
                    filterExpression = "([Application] = '" + e.Value + "')" 
        
                    RadGrid1.MasterTableView.FilterExpression = filterExpression 
        
                    RadGrid1.MasterTableView.Rebind() 
        
                End Sub
