How to delete row that i have added in gridview?


this my code:

protected void BindGrid(int rowcount)
        {

            DataTable dt = new DataTable();

            DataRow dr;

            dt.Columns.Add(new System.Data.DataColumn("Document No", typeof(String)));

            dt.Columns.Add(new System.Data.DataColumn("Document Title", typeof(String)));

            dt.Columns.Add(new System.Data.DataColumn("Revision", typeof(String)));

            dt.Columns.Add(new System.Data.DataColumn("File", typeof(String)));



            if (ViewState["CurrentData"] != null)
            {

                for (int i = 0; i < rowcount + 1; i++)
                {

                    dt = (DataTable)ViewState["CurrentData"];

                    if (dt.Rows.Count > 0)
                    {
                        dr = dt.NewRow();
                        dr[0] = dt.Rows[0][0].ToString();
                    }

                }

                dr = dt.NewRow();

                dr[0] = DropDownList1.Text;

                dr[1] = DropDownList2.Text;

                dt.Rows.Add(dr);

            }

            else
            {

                dr = dt.NewRow();

                dr[0] = DropDownList1.Text;

                dr[1] = DropDownList2.Text;

                dt.Rows.Add(dr);

            }
            if (ViewState["CurrentData"] != null)
            {

                GridView1.DataSource = (DataTable)ViewState["CurrentData"];

                GridView1.DataBind();

            }

            else
            {

                // Bind GridView with the initial data assocaited in the DataTable

                GridView1.DataSource = dt;

                GridView1.DataBind();

            }

            // Store the DataTable in ViewState to retain the values

            ViewState["CurrentData"] = dt;
        }






for button add

protected void Button1_Click(object sender, EventArgs e)
       {
           if (ViewState["CurrentData"] != null)
           {

               DataTable dt = (DataTable)ViewState["CurrentData"];

               int count = dt.Rows.Count;

               BindGrid(count);

           }

           else
           {

               BindGrid(1);

           }




gridview:

<asp:GridView ID="GridView1" AutoGenerateDeleteButton="true" OnRowDeleting="GridView1_RowDeleting" runat="server" CssClass="datagridview">
                </asp:GridView>

Hi,

Try this,

DataTable dt = new DataTable();
        dt = (DataTable)ViewState["CurrentData"];

        for(int i=0;i<dt.rows.count;i++)>
        {
            if (dt.Rows[i][0].ToString() == "Your value")
            {
                dt.Rows[i].Delete();
            }
        }
        GridView1.DataSource = dt;
        GridView1.DataBind();
        ViewState["CurrentData"] = dt;
