Grid View for ASP.NET MVC - How to create a custom page size item with the Show All Records button

This example demonstrates how to create the grid's footer template, add a custom page size item to the template, and display the Show All Records button.

Overview

Call the grid's SetFooterRowTemplateContent method to add custom pager elements to the grid's footer.

GridViewPartial.cshtml

settings.SetFooterRowTemplateContent(c => {
    Html.RenderPartial("FooterRowPartial", c);
});

FooterRowPartial.cshtml

@Html.DevExpress().ComboBox(settings => {
    settings.Name = "cbPageSize";
    settings.Width = System.Web.UI.WebControls.Unit.Pixel(50);
    for (int i = 0; i < pageSizes.Length; i++) {
        settings.Properties.Items.Add(pageSizes[i].ToString(), pageSizes[i]);
    }
    settings.Properties.Items.Add("All", -1);
    if (Model.Grid.SettingsPager.Mode == GridViewPagerMode.ShowAllRecords) 
        settings.SelectedIndex = settings.Properties.Items.Count - 1;
    else
        settings.SelectedIndex = Array.IndexOf(pageSizes, Model.Grid.SettingsPager.PageSize);
    settings.Properties.ClientSideEvents.SelectedIndexChanged = "function(s, e) { GridView.PerformCallback({ pageSize: s.GetValue() }); }";
}).GetHtml()

You can also display the Show All Records button in the page size item of the built-in pager.

@Html.DevExpress().GridView(settings => {
    settings.Name = "GridView";
    settings.SettingsPager.PageSizeItemSettings.Visible = true;
    settings.SettingsPager.PageSizeItemSettings.ShowAllItem = true;
    <!-- ... -->
});
