Want to show a custom error message box instead of default errorMessageForm (stiJsViewerForm)

[shyam.pundkar]

Hi,

We want to show our application specific message box whenever the report generation fails.
ATM it shows stimulsoft error message stiJsViewerForm.

report.web.error.message.png (3.04 KiB) Viewed 6490 times

Is there any way to know if the report generation failed, at the client side using StiJsViewer? any events?

Thanks
Shyam

Hello,

Which error do you have, in which moment it occurs?

Thank you.

Hi,

We give data to viewer and do postaction.
jsReportViewer.options.formValues = {
selectionData: jsonData
};
model.jsReportViewer.postAction();
so all control is handed over to viewer now. which does further call, rendering,error handling etc

We do business validation while generating the report on the server side. On validation fail we return our own customized error message, eg. 'xyz data is missing please contact admin'. The viewer handles our customized message through its own error handling mechanism on client and show it.

The requirement is that the reportviewer should not handle the error by itself instead it should let the host to handle that. so that we can execute our own business logic on error.
Please let me know if have more questions...

Hello,

Please try to check the following code:

Code: Select all

var viewer = new Stimulsoft.Viewer.StiViewer(viewerOptions, "StiViewer", false);
viewer.renderHtml("content");

var errorForm = viewer.jsObject.controls.forms.errorMessageForm || viewer.jsObject.InitializeErrorMessageForm();
errorForm.show("Message text!");

Thank you.

Hi,

we dont use renderhtml(). we use postaction().
once we call viewer.postaction() we dont get any call back notifying the report generation outcome.
Can you recommend a way for call back from viewer please? i guess that way we will know if anything goes wrong in the viewer.

Thanks
Shyam

Please check the following code:

var viewer = new Stimulsoft.Viewer.StiViewer(viewerOptions, "StiViewer", false);
            viewer.renderHtml("content");

            //ovveride callback method
            viewer.jsObject.showReportPage_ = viewer.jsObject.showReportPage;

            viewer.jsObject.showReportPage = function (data, jsObject) {
                //postAction callback here
                if (typeof data == "string" && data.indexOf("ServerError:") == 0) {
                    //for example
                    var errorForm = viewer.jsObject.controls.forms.errorMessageForm || viewer.jsObject.InitializeErrorMessageForm();
                    errorForm.show("Message text!");
                }
                viewer.jsObject.showReportPage_(data, jsObject);
            }

Hello,

You can use the following code:

Code: Select all

//where jsMvcViewer1 - "js" + Viewer ID

    jsMvcViewer1.onready = function () {
        //ovveride callback method
        jsMvcViewer1.showReportPage_ = jsMvcViewer1.showReportPage;

        jsMvcViewer1.showReportPage = function (data, jsObject) {
            //postAction callback here
            if (typeof data == "string" && data.indexOf("ServerError:") == 0) {
                //for example
                var errorForm = jsMvcViewer1.controls.forms.errorMessageForm || jsMvcViewer1.InitializeErrorMessageForm();
                errorForm.show("Message text!");
            }
            jsMvcViewer1.showReportPage_(data, jsObject);
        }
    }

Thank you.
