ShieldUI grid data from codebehind datatable

Question

I implemented a jQuery gridview with ShieldUI. The thing i am having problems with is the datasource for the grid.

Here is their example: http://demos.shieldui.com/web/grid-general/basic-usage

I need to send the data from a datatable that is created in code behind.

Is it possible to send such data to ShieldDataSource?

Thank you.

Answer 1

you can do the following in the page load method and just set the Data property of the DataSource to testData in the aspx and it would work.

<shield:ShieldDataSource ID="shieldDataSource" runat="server" Data="testData"> 
    </shield:ShieldDataSource>
    <shield:ShieldGrid ID="grid" runat="server" ClientDataSourceID="shieldDataSource">
        <Sorting Enabled="true" />
        <Columns>
            <shield:GridColumn Field="Id" />
            <shield:GridColumn Field="Name" />
            <shield:GridColumn Field="Category" />
            <shield:GridColumn Field="Date" />
            <shield:GridColumn Field="Available" />
        </Columns>
    </shield:ShieldGrid>


protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                var dt = new DataTable();
                dt.Columns.Add(new DataColumn("Id", typeof(int)));
                dt.Columns.Add(new DataColumn("Name", typeof(string)));
                dt.Columns.Add(new DataColumn("Category", typeof(int)));
                dt.Columns.Add(new DataColumn("Date", typeof(DateTime)));
                dt.Columns.Add(new DataColumn("Available", typeof(bool)));

                var row = dt.NewRow();
                row["Id"] = 1;
                row["Name"] = "test";
                row["Category"] = 2;
                row["Date"] = DateTime.Now;
                row["Available"] = true;
                dt.Rows.Add(row);

                var source = (from r in dt.AsEnumerable()
                              select new
                              {
                                  Id = r["Id"],
                                  Name = r["Name"],
                                  Category = r["Category"],
                                  Date = r["Date"],
                                  Available = r["Available"],
                              }).ToList();
                var script = "window.testData = " + Shield.Mvc.UI.Common.Serialization.JavaScriptSerializer.Serialize(source);
                ClientScript.RegisterClientScriptBlock(this.GetType(), "TableData", script, true);
            }
        }
