Left click hold and select multiple markers within the
selection rectangle
|
We do not support the selection of multiple markers with
interaction in the Maps component. We have considered it as a feature and
added it to our features request list. We do not have immediate plans to
implement this feature. However, this feature will be available in any of our
future releases. Please find the feedback link below to keep track of the
feature.

How to multiselect markers?
|
We support selecting multiple markers in the Maps
component by selection each markers individually in the Maps. We can enable
multi-select by setting “EnableMultiSelect” as “true” in the “MapsMarkerSelectionSettings”
tag. Please find the code snippet for the same below.
Code snippet:
|
<MapsMarkerSettings>
<MapsMarker Visible="true"
TValue="PopulationCityDetails"
DataSource="@PopulatedCities" Shape="MarkerType.Circle"
Fill="red" AnimationDuration="0" Width="30"
Height="30">
<MapsMarkerBorder Color="#285255" Width="2" />
<MapsMarkerSelectionSettings Enable="true"
EnableMultiSelect="true"
Fill="yellow"></MapsMarkerSelectionSettings>
</MapsMarker>
</MapsMarkerSettings>
|
|
|
Are there any events to receive the selected markers
|
We can get the details(respective object in the data
source) of the selected markers from the “Data” property of the event
argument (MarkerClickEventArgs) of the “OnMarkerClick” event.
Please find the code snippet for the same below.
Code Snippet:
|
<SfMaps>
<MapsEvents
OnMarkerClick="MarkerClickEvent"></MapsEvents>
……
</SfMaps>
@code {
IDictionary<string, string> data = new
Dictionary<string, string>();
public void
MarkerClickEvent(MarkerClickEventArgs args)
{
data =
args.Data;
}
}
