Hi ,
How could i set parentheses for negatives using boundcolumns without currency symbol something like this

(1,980.70)

actually i have this dataformatstring , and its cool 'cause completes the decimal position with #.00 always

    
            <telerik:GridBoundColumn    DataField="Noviembre" Aggregate="Sum" HeaderStyle-HorizontalAlign="Right" DataFormatString="{0:N2}" DataType="System.Decimal" 
        
                                                                                        FooterAggregateFormatString="{0:N2}" FooterStyle-Font-Bold="true"> 
        
                                                                                         <HeaderStyle HorizontalAlign="Right" /> 
        
                                                                                         <ItemStyle HorizontalAlign="Right" /> 
        
                                                                                 <FooterStyle HorizontalAlign="Right" /> 
        
                                                            </telerik:GridBoundColumn>

wih this code and setting the dataformatstring={"0:C"} parentheses works but whit the currency symbol

    
            CultureInfo ci = new CultureInfo("es-PE"); 
        
            ci.NumberFormat.CurrencyNegativePattern = 14; 
        
            System.Threading.Thread.CurrentThread.CurrentCulture = ci;

i hope you can help me, thanks

Problem with OnClientLoad

Hello Everybody,

I have problem with OnClienLoad property. We create dynamicly radeditor code behind like this:

    
             Dim editor As Control = CreateDhtmlEditor("editor")  
        
             Label1.Controls.Add(editor) 'Add control to label  
        
             'Find RadEditor and add Ajax to component  
        
             Dim RadEd As Telerik.WebControls.RadEditor = CType(Page.FindControl("editor"),Telerik.WebControls.RadEditor)  
        
            RadAjaxManager1.AjaxSettings.AddAjaxSetting(btnOpenTemplate, CType(RadEd, Telerik.WebControls.RadEditor), AjaxLoadingPanel1)  
        
             RadAjaxManager1.AjaxSettings.AddAjaxSetting(btnOpenTemplate, CType(RadEd, Telerik.WebControls.RadEditor), AjaxLoadingPanel1)  
        
            'add client side event  
        
            RadEd.OnClientLoad="OnClientLoad"

Basicly this is how we create Editor to Webpage. I have written my onLoadevent into page.aspx file. This is written onload event on codebehind

    
             function OnClienLoad(editor)  
        
            {  
        
               alert('Editor');  
        
            }

Every time i get following error message:
Exception on excetuing Client event onclientload error:'OnClientLoad' is undifined.

Please some tell what I am doing Wrong. We are using RadEditor 7.12.

GridBoundColumn to GridDropDownColumn

I have a RadGrid with AutoGenerated GridBoundColumns.

This works great, however i am trying to make one of these columns a GridDropDownColumn from the ColumnCreated() event. I can't find any examples of this anywhere. This post: http://www.telerik.com/help/aspnet/grid/grdcustomizeconfiguregriddropdowncolumn.html is not helping me very much being that all my columns are GridBoundColumns, i have no GridDropDownColumns and (GridDropDownListColumnEditor)(editMan.GetColumnEditor()) fails every time.

Can someone tell me how to set a GridBoundColumn as a GridDropDownColumn?

Thanks,

Duncan

sample if ______________________ is the xAxis and 12345 is the label.

I am setting the following values.

                                radChart.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 45;         
                        radChart.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Color = System.Drawing.Color.Black;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Bottom;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.Auto = false;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.X = 200;         
                        radChart.PlotArea.XAxis.AxisLabel.Appearance.Position.Y = 125;

RadAjaxManager configuration in Custom Control

I have created custom control for RadRotator, the functionality of control is like http://demos.telerik.com/aspnet-ajax/rotator/examples/gallery/defaultcs.aspx. I am using RadAjaxManager to show the details section on click of the strip image. But its refreshing the whole page, instead of just refreshing the details section.

It will be highly appreciated if you could provide me the steps or sample code for configuring the RadAjaxManager in custom controls.

I am getting folowing error on the page

    
            Message: Sys.ArgumentNullException: Value cannot be null.  
        
            Parameter name: panelsCreated[2]

Thanks

Tool Tip not visible in IE8 but is visible in IE7!!

Hi All,

I have developed a custom control (a .cs file not .ascx file) in which I have used a RadRotator. I require a Rich Text ToolTip(consist of an image and some text) on the mouse hover event, on any of the images of the RadRotator. So I have used a RadToolTip.
The radrotator ItemTemplate consists of an image, a RadToolTip and some literal controls.

The problem I am facing is that I am able to see the tool tip correctly in IE 7 but in IE8 it does not appear at all.
Another issue that I am facing is that in Safari browser the ToolTip appears on the top of the browser(irrespective of the rotator position when scrolled).

Has anyone faced such kind of issue??
Any solution or hints will be appreciated.

Thanks.

Regards,
Manoj

Web Server hangs when setting AutoScale to False on the YAxis

Hi there,

I have a Line chart that displays two series. I have AutoLayout set to true. When the maximum values of the series is equal to the maximum label value of the Y axis, I get a flat line at the top of the chart. In theory this is fine, but the line appears cut off, so you only see half of it.

To work around this, I try to set the MaxValue on the YAxis programmatically to the maximum value of the items + 10%. So, if the highest items are 35000, I set MaxValue to 38500. In order for this to work, I also need to set AutoScale to False. However, as soon as I do that, my WebDevServer.exe hangs, and consumes all memory and CPU until it crashes. As soon as I remove the attribute, the page behaves OK, but the chart is cut off again.

You can see a repro scenario in this test project
http://imar.spaanjaars.com/Downloads/Other/TelerikChartIssue2.zip

I am not programmatically setting this attribute, but through markup:

<YAxis MaxValue="700000" > <%--AutoScale="false"--%>

If you add the AutoScale attribute to the YAxis element, the server hangs.

Is there a work around for this? How do I create some "padding" between the actual series line at the top of the PlotArea?

Thanks for looking into this.

Dependant combos on grid?

Dependant combos on grid

Is possible to have dependant combos on a grid that are bound server side?

What I want to happen is somehow rebind the DataSource when another combo box in the grid changes.

So for example Combo A was Continents and Combo B was counties I would want to filter the country list (Combo B) depending on what is selected in the continents (Combo A). I can’t see any server events that fire upon selecting a combo within a grid.

Note that to further complicate things my columns are dynamically created.

Any help would be much appreciated!!!

Below is a shortened extract of my code:-

protected void uxResults_ItemDataBound(object sender, GridItemEventArgs e)

{

GridDropDownListColumnEditor

combo = null;

editMan = editedItem.EditManager;

GridDataItem item = (GridDataItem)e.Item;

if (e.Item is GridEditableItem )

{

if ((e.Item as GridEditableItem).IsInEditMode)

{
