Delete Grid rows from server side
Posted: May 28, 2014 8:29 AM

Here is the source:

JAVASCRIPT:

function Button2_onclick() 

{

    var grid = ISGetObject("WebGrid1");

    var table = grid.RootTable;

    alert(grid.TotalRows);


   var row4 = grid.RootTable.GetRow(0);

   var row5 = grid.RootTable.GetRow(1);

   var row6 = grid.RootTable.GetRow(2);

}

SERVER SIDE:

   using System;

using System.Data;

using ISNet.WebUI.WebGrid;

using System.Web.UI.WebControls;

using System.Drawing;

using ISNet.WebUI;

using System.Collections.Generic;


public partial class _Default : System.Web.UI.Page

        WebGrid1.PrepareDataBinding += new DataSourceEventHandler(WebGrid1_PrepareDataBinding);

    }


    protected override void OnPreRender(EventArgs e)

    {

        WebGrid1.RootTable.Rows[3].Visible = false;

        WebGrid1.RootTable.Rows[2].Visible = false;

       // WebGrid1.RootTable.Rows.RemoveAt(2);

    }


    protected void ctlUltraGrid_InitializeLayout(object sender, ISNet.WebUI.WebGrid.LayoutEventArgs e)

    {

        if (!IsPostBack)

        {

            //Create the column

            WebGridColumn wcol = new WebGridColumn("ItemName", "ItemName");

            WebGrid1.RootTable.Columns.Add(wcol);


            WebGridColumn wcol1 = new WebGridColumn("Discount", "Discount");

            WebGrid1.RootTable.Columns.Add(wcol1);



            WebGridColumn wcol2 = new WebGridColumn("Price", "Price");

            WebGrid1.RootTable.Columns.Add(wcol2);


            WebGrid1.RootTable.Layout.ColumnHeaders = ColumnVisibility.No;

        }

        e.Layout.ClientSideEvents.OnRowSelect = "DoRowSelect";

    }

        table.Columns.Add("Drug", typeof(string));

        table.Columns.Add("Patient", typeof(string));


        //

        //

        table.Rows.Add(25, "Indocin", "David");

        table.Rows.Add(50, "Enebrel", "Sam");

        table.Rows.Add(10, "Hydralazine", "Christoff");

        table.Rows.Add(13, "Hydralazine1", "Christof1f");

            else

                item.EditType = EditType.NoEdit;

        }


        var dt = WebGrid1.GetCachedDataSource();

        ViewState["oo"] = dt;


    }
