Hi, I'm using a ClientDataSource with a Grid to communicate with a webservice from client-side.

The webservice returns a custom response for any request: {"ErrorMessage":(error message or null),"IsSuccessful":(boolean),"Result":[(result of request)]}.

In the ClientDataSource I defined the schema as follows to check for server errors

And this function to show the error:

My problem is that when I try to remove an item from the clientdatasource and I get a custom error,the item is still removed from the clientdatasource and the grid which is not an effect I'm looking for.

For the clientdatasource remove/destroy I'm using a function:

Before adding ErrorsName in the schema I was check the IsSuccessful on success and call options.error, in this case the clientDataSource remove the item but the grid did not rebind !

On the same topic is it possible to check if IsSuccessful is false instead of ErrorMessage is null to generate an error and get the error message from ErrorMessage?

In case of remove, the Result will be a boolean, can I also prevent the clientDataSource from removing an element if if Result is false?

I am adding a default initial filter from the code-behind, but I'm getting an error:
System.Web.Query.Dynamic.ParseException

• MyGrid :

• Code behind :

"([CCE_DateReception]>=DateTime.Parse(\""+DefaultDateInterval+"\")) "
Is based on Current filter expression when i use the Build-in grid filter.
But I also try:
"([CCE_DateReception] >= \"" + DefaultDateInterval + "\" ) "


The Error occure on RG_Lst_CS.Rebind() or RG_Lst_CS.MasterTableView.Rebind()
And EnableLinqExpressions="true" do not look to do the trick.

Hi 

I use RadWizard and create 10 WizardStep, each step content 10 textbox and 10 Custom Validation.

I use client function to validate these textbox, like below , the code will help me to find which textbox are repeated.

My question is when step 2 textbox value and step 1 textbox value repeated, the validator fired. I wish each step just only have it validator, each step will not interference each other. How Can I do ?

  <script type="text/javascript">
        function validateTxt(sender, args) {
            var txts = new Array();
            args.IsValid = true;
            txts = document.getElementsByTagName('input')  
            var valus = new Array();
            for (i = 0; i < txts.length; i++) {  
                if (txts[i].type == 'text') { 
                    if (isNaN(txts[i].value)) {
                        args.IsValid = false;
                        break;
                    } else {  
                        for (j = 0; j < valus.length ; j++) {
                            if (valus[j] == txts[i].value.trim()) {  
                                args.IsValid = false;
                                break;
                            }
                        }
                        if (txts[i].value.trim() != '') {   
                            valus[valus.length] = txts[i].value.trim();
                        }
                    }
                }
                if (args.IsValid == false) {
                    break;
                }
            }
        }

I have a button inside RadAjaxPanel and i want to export it to the Excel Sheet, Below is the code i had written to do this task. If i removed the RadAjaxpanel then i can export the datatable into excel sheet. But when trying to export  it to Excel using radajax panel, I'm getting this error: Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed."

Hi, everyone,

As far as I know, RadEditor doesn't have a page break functionality when HTML is exporting to DOCX. I've found a solution for this:

DocxFormatProvider provider = new DocxFormatProvider();
HtmlFormatProvider htmlProvider = new HtmlFormatProvider();

List<string> result = this.PrepareStringToExport(htmlPage); //result is a list with divided "pages"
RadFlowDocument newDoc = new RadFlowDocument();
RadFlowDocumentEditor newEditor = new RadFlowDocumentEditor(newDoc);
RadFlowDocument document;
foreach(string element in result)
{
document = new RadFlowDocument();
document = htmlProvider.Import(element);
newEditor.InsertDocument(document);
newEditor.InsertBreak(BreakType.PageBreak);
}
byte[] byteArray = provider.Export(newEditor.Document);
string fileName = "filename.docx";
Utils.SendBytesAsFileToClientWithAjax(Response, fileName, byteArray);

If there is a cleaner solution, let me know

Best regards

Marcin

Hello,

I have an OrgChart and a couple of labels and an image that I want to export to PDF using the RadClientExportManager.
Code .aspx: 

However my swedish special characters doesn't show properly in the PDF.
I've been using this demo http://docs.telerik.com/devtools/aspnet-ajax/controls/clientexportmanager/how-to/exporting-special-characters
and it works as expected.

What do I need to do to get it to work with the orgChart?

Any suggestions appreciated

Regards

Janne

I noticed that the markers on the map looks mispositioned on many devices, like shifted to north/east.

I got this problem with my Android phone and even with a Surface pro, whatever the browser I 'm using.

You can see it even with the online demo:
http://demos.telerik.com/aspnet-ajax/map/examples/overview/defaultcs.aspx

On PC:

On my phone:

I think it's just a css issue with the markers. I really need a quick solution to the problem. Any ideas? :/

Hi Team,

I have a Radgrid which has DateTime Column with enable range filter. I am using AllowCustomPaging="True" And I am displaying the date as "24/11/2016 15:31:15" and I want that when I choose from date and To date the filter expression should format the filter date.

For example From date is "23/11/2016" and To Date is "24/11/2016" then it should change to "20161123" and "20161124" before passing to database.

Could you please help me on this.
