Freinds,

We are using RAD Chart control to display bar graphs in our ASP.NET web application which worked fine on Dev and QA servers. But when it was moved to production box, it worked fine first day but next day it started giving error "Error Loading Chart Image". Please find the trace below for your reference

Request path: /OneViewDashboard/ChartImage.axd User host address: 172.21.253.97 User: PMSI\SeK4211 Is authenticated: True Authentication Type: Negotiate Thread account name: PMSI\oneviewprodsvc Thread information: Thread ID: 50 Thread account name: PMSI\oneviewprodsvc Is impersonating: False Stack trace: at System.Drawing.Image.Save(Stream stream, ImageCodecInfo encoder, EncoderParameters encoderParams) at Telerik.Web.UI.ChartHttpHandler.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Please note that it started working after restarting application pool but need to know what could have caused this issue. Thanks in advance.

Thanks,
Satish

OnClientItemChecked event is not firing

Hi,

We are using Radio Combobox with multi select checkbox. I need to fire a client side event on checbkox click and henceforth I would like to use OnClientItemChecked. But this event is not firing. If my page is under updatepanel then could it create an issue.

Here is my below code-

<script language="javascript" type="text/javascript">
function OnClientItemChecked(sender, eventArgs) {
var item = eventArgs.get_item();
}
</script>

<telerik:RadComboBox ID="ddlClient" runat="server" Width="172px" AllowCustomText="True" OnClientDropDownClosed="onDropDownClosing" OnClientItemChecked="OnClientItemChecked"
HighlightTemplatedItems="true" Height="200px" EmptyMessage="Select Clients" Enabled="false" OnItemDataBound="ddlClient_ItemDataBound" CheckBoxes="True" EnableCheckAllItemsCheckBox ="true">
<Localization CheckAllString="Select All" />
</telerik:RadComboBox>

Thanks,
Punit Singhi

RadAysncUpload working in FireFox but not in IE7

Hi,

RadAsyncUpload is working allright in IE 7 when the application is run locally but on deploying the same to the server, the file upload doesnot work in IE7 but does work in FireFox. In IE 7, It seems stuck and after a few mintues gives the red symbol indicating a failure.
Can any one please shed some light on this ?
thanks in advance. \

An update: it does not work in IE 8 also; I am also not seeing any error on using OnClientFileUploadFailed. OnClientFileUploading returns the message alert given in javascript. After that it just stays with the orange ball blinking. it never goes to the next event and never fails .
Also i have made sure that the app pool user has write permissions to the app_data/RadUploadTemp
Please help.

Update after close window but not vCard

Currently have a RadGrid that contains user information which they can click to edit the record or click on a button to download the vCard. I would like it to refresh the grid after the user has closed the window. However I do not need it to refresh if they click to download the vCard. Can't seem to have it both ways at this time. Any suggestions? Tried removing the "Ajax" refresh but not positive it was working properly.

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

function onRequestStart(sender, args) {

if (args.get_eventTarget().indexOf("vCard") >= 0)

var grid = $find("<%= _gridContacts.ClientID%>");

var rowControl = grid.get_masterTableView().get_dataItems()[rowIndex].get_element();

grid.get_masterTableView().selectItem(rowControl, true);

window.radopen("Contacts.aspx?Contact_ID=" + id, "UserListDialog");

return false;

}

function ShowInsertForm() {

window.radopen("Contacts.aspx", "UserListDialog");

return false;

}

function RowDblClick(sender, eventArgs) {

window.radopen("Contacts.aspx?Contact_ID=" + eventArgs.getDataKeyValue("Contact_ID"), "UserListDialog");

}

function refreshGrid(arg) {

if (!arg) {

Change text align and direction of RadHtmlChart data

I have a chart:

<telerik:RadHtmlChart ID="chrtInvestmentAmount" runat="server" Transitions="true" DataSourceID="SqlDataSource1" Height="256px" Skin="Glow" Width="1024px" RenderMode="Auto">

<PlotArea>

<Series>

<telerik:ColumnSeries DataFieldY="InvestmentsAmount" Name="כמות משקיעים"/>

</Series>

<XAxis DataLabelsField="Month">

<TitleAppearance Text="חודש" />

</XAxis>

<YAxis>

<TitleAppearance Text="כמות משקיעים" />

</YAxis>

</PlotArea>

</telerik:RadHtmlChart>

Now in my body tag I have set the direction of the page to rtl, and when i do that the whole chart gets messed up, the text gets cut off a little and all in all it just doesent look good:

http://i.stack.imgur.com/On2XQ.jpg

for some reason it just gets all messed up. Isn't there some small piece of code which can fix this?
And while i'm asking, another problem i have is after setting the chart type (bars,lines and so on...) it does not update it and i also notice no line of code is added to the HTML. I dont know if something needs to be added, either way i cant change the chart type. Is there some kind of code which can change the chart type?

Thanks.
