Hello,
I set the dashboard parameter value inside the "dxDBViewer_CustomParameters" event.
C#protected void dxDBViewer_CustomParameters(object sender, DevExpress.DashboardWeb.CustomParametersWebEventArgs e)
{
try
{
var loginNameParameter = e.Parameters.FirstOrDefault(p => p.Name == "pCurrentLoginName");
if (loginNameParameter != null)
{
loginNameParameter.Value = currentUserLoginName;
}
}
catch (Exception ex)
{
}
}
I am trying to get the parameter value at the client side inside "onDashboardTitleToolbarUpdated" event.
JavaScriptfunction onDashboardTitleToolbarUpdated(s, e) {
debugger;
var caption = e.Options.contentItems.filter(function (item) {
return item.name === 'dashboard-title'
});
if (caption.length > 0) {
var parameters = webViewer.GetParameters();
var parameter1 = parameters.GetParameterByName("pCurrentLoginName");
var parameter1Value = parameter1.GetValue();
caption[0].text = parameter1Value;
}
}
The parameter value is coming out empty. Please suggest a workaround.
Hi Kalai,
The custom parameter values supplied via the CustomParameters event are used only for data selection. With this event, you can "silently" customize parameter values according to your requirements. This feature is not meant to be used on a client-server communication channel; it's a security measure meant for user-level data filtering.
Before recommending any particular solution, could you please elaborate on the overall usage scenario? What does that
pCurrentLoginNamevariable represent? Judging by the name, that would be the user's name from the Session object. In this case, I assume you could just insert it into the page during its initial rendering (e.g., as a hidden field). Do you see any issue with this alternative? Please let us know.
