Call Custom Actions in Dataverse using Web API – Quick Recap

Hi Folks,

Here is how you can quickly call action using Web API, with this method you can execute a single action, function, or CRUD operation. In the below example, let’s see how you can call an action. Here is function…to achieve this..

var formContext = executionContext.getFormContext();
var message = "Please enter a valid NRIC Number";
var uniqueId = "nric_valid";
var NRIC = formContext.getAttribute("new_nric").getValue();
if(NRIC !== null)
{
var execute_ValidateNRIC = {
NRIC: NRIC, // Call this function only when NRIC value which is non-null
getMetadata: function () {
return {
boundParameter: null,
parameterTypes: {
NRIC: { typeName: "Edm.String", structuralProperty: 1 }
},
operationType: 0,
operationName: "new_ValidateNRIC",
outputParameterTypes: {
IsValid: { typeName: "Edm.Boolean" }
}
};
}
};
Xrm.WebApi.execute(execute_new_ValidateNRIC).then(
function success(response) {
if (response.ok) {
response.json().then(function (data) {
if (!data.IsValid) {
formContext.getControl("new_nric").setNotification(message, uniqueId);
} else {
formContext.getControl("new_nric").clearNotification(uniqueId);
}
}).catch(function (error) {
Xrm.Navigation.openAlertDialog("Error occured from Validate NRIC "+error);
});
}
}
).catch(function (error) {
Xrm.Navigation.openAlertDialog(error.message);
}).catch(function (error) {
Xrm.Navigation.openAlertDialog(error.message);
});
}
}

This example details with Unbound action, which is not tagged to any entity, however if in case on Bound action, you will specify the entity name for bound parameter instead of null. You need to specify the Metadata accordingly for your Action. Let’s understand it’s syntax first…

Xrm.WebApi.online.execute(request).then(successCallback, errorCallback);

Parameters

Is your plugin not running? Have you debugged? Plugin doesn’t run but your operation is successful when debugging…then try this out

Hi Folks,

Last few weeks was very busy for me, I missed interacting with the community.

Here I would like to share one tip which can greatly help your debugging…

Just to give a little background, I was working with the Plugins for Dynamics 365 recently where I was working with API, the Plugin seem to work fine when debugged using Profiler, I tested the piece of the Plugin Code in Console, it worked either, but Plugin is not working when the respective action which triggers the Plugin is being fired. I scratched my head, what is the problem…

Just then, I tried using the below block of code, replaced the catch block of Plugin Code with below code.

catch(WebException ex)
{
string stringResponse = string.Empty;
int statusCode;
using (WebResponse response = ex.Response)
{
HttpWebResponse httpResponse = (HttpWebResponse)response;
statusCode = (int)httpResponse.StatusCode;
using (Stream data = response.GetResponseStream())
using (var reader = new StreamReader(data))
{
stringResponse = reader.ReadToEnd();
}
using (var ms = new MemoryStream(Encoding.Unicode.GetBytes(stringResponse)))
{
}
}

Soon, I observed from the detailed error message above function posted, it is failing because of version problem of the referenced DLL and current DLL version was not supported with my assembly.

Soon I was able to reference my Plugin with correct DLL version which fixed the issue. No further debugging was needed.

Hope this helps…

Cheers,
