Display DataTable in a JavaScript alert message

   ... {
        foreach (ListEntry.Custom listrow in mySpread.Elements)
        {
            DC = 
                myTable.Columns[listrow.LocalName] ?? myTable.
                     Columns.Add(listrow.LocalName);

            myDR[DC] = listrow.Value;


        }
        myTable.Rows.Add(myDR);
    }

    DataTable uni = new DataTable();
    DataTable mn = new DataTable();
    mn= myTable.AsEnumerable().Reverse().CopyToDataTable();

    uni = RemoveDuplicateRows(mn, "itemname");

    DataTable filteredDataTable = uni.Select("quantity = " + "4").CopyToDataTable();

To display the content of filteredDataTable in a JavaScript alert box, I have utilized Google Spreadsheet as a database.

Answer №1

The fastest approach to accomplish this task is by converting the dataTable into XML format and then presenting it in an alert box. Follow this example:

System.IO.StringWriter writer = new System.IO.StringWriter();
filteredDataTable.WriteXml(writer, true);

Page.ClientScript.RegisterStartupScript(
    this.GetType(),"script", "alert('"+writer.ToString()+"');",true);

Sincerely.
