CustomJSPropertiesEventArgs.Properties Property

Gets a collection of temporary client properties.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v22.1.dll

Declaration

public Dictionary<string, object> Properties { get; }

Property Value

Type Description
Dictionary<String, Object>

The collection of property names and values.

Remarks

Run Demo: (Web Forms) ASPxGridView - Select All Rows Run Demo: (MVC) GridView - Select All Rows

Use the event parameter’s Properties property to add new properties that can be accessed on the client.

Note

The only requirement is that property names must begin with the ‘cp’ prefix to avoid rewriting the object’s base properties.

Example

Web Forms:

<dx:ASPxGridView ID="grid" OnCustomJSProperties="GridView_CustomJSProperties" ...>
    ...
</dx:ASPxGridView>
protected void GridView_CustomJSProperties(object sender, ASPxGridViewClientJSPropertiesEventArgs e) {
    e.Properties["cpVisibleRowCount"] = grid.VisibleRowCount;
    e.Properties["cpFilteredRowCountWithoutPage"] = GetFilteredRowCountWithoutPage();
}
function GetSelectedFilteredRowCount() {
    return grid.cpFilteredRowCountWithoutPage + grid.GetSelectedKeysOnPage().length;
}

MVC:

settings.CustomJSProperties = (s, e) => {
    var grid = s as MVCxGridView;
    e.Properties["cpVisibleRowCount"] = grid.VisibleRowCount;
    e.Properties["cpFilteredRowCountWithoutPage"] = GetFilteredRowCountWithoutPage(grid);
};
function GetSelectedFilteredRowCount() {
  return grid.cpFilteredRowCountWithoutPage + grid.GetSelectedKeysOnPage().length;
}
