Specifies the JavaScript function that handles the client-side ParametersSubmitted event.

Namespace: DevExpress.AspNetCore.Reporting.WebDocumentViewer

Assembly: DevExpress.AspNetCore.Reporting.v21.1.dll

NuGet Package: DevExpress.AspNetCore.Reporting

Declaration

C#

public WebDocumentViewerClientSideEventsBuilder ParametersSubmitted(
    string callback
)

VB.NET

Public Function ParametersSubmitted(
    callback As String
) As WebDocumentViewerClientSideEventsBuilder

Parameters

Name	Type	Description
callback	String	The name of a JavaScript function or entire JavaScript function code that runs when the ParametersReset event is fired.

Returns

Type	Description
WebDocumentViewerClientSideEventsBuilder	A WebDocumentViewerClientSideEventsBuilder object that can be used for method chaining.

Remarks

The ParametersSubmitted event is raised when the user enters parameter values and clicks the Submit button in the Preview Parameters panel.

You can handle this event to change parameter values passed to the server because Parameter Model values remain unchanged and do not cause errors on the client side.

Examples

The following code changes the parameter value sent to the server and collapses the Parameters panel when the user clicks the Submit button:

ASP.NET Core

<script type="text/javascript" id="script"> 
    function onParametersSubmitted(s, e) {
         e.Parameters.filter(function (p) { return p.Key == "YourParameterNameHere"; })[0].Value = "SomeValue";
        var preview = s.GetPreviewModel();
        if (preview) {
            preview.tabPanel.collapsed(true);
        }
    }
</script>

@{
    var viewerRender = Html.DevExpress().WebDocumentViewer("DocumentViewer")
        .Height("1000px")
        .ClientSideEvents(configure => configure.ParametersSubmitted("onParametersSubmitted"))
        .Bind("TestReport");
    @viewerRender.RenderHtml()
}

The following code passes a custom object as a report parameter (MyComplexParameter) to the server. A custom object in this code snippet contains data selected in a custom editor (MyComplexEditor) specified in the CustomizeParameterEditors event:

ASP.NET Core

<script type="text/javascript" id="script">
    function onParametersSubmitted(s, e) {
        e.Parameters.filter(item => item.Key === "MyComplexParameter")[0].Value = JSON.stringify(myComplexEditorModel.value())
    }
</script>

@{
    var viewerRender = Html.DevExpress().WebDocumentViewer("DocumentViewer")
        .Height("1000px")
        .ClientSideEvents(configure => configure.ParametersSubmitted("onParametersSubmitted"))
        .Bind("TestReport");
    @viewerRender.RenderHtml()
}
