推荐答案

尝试.

'On GridView Row Command Event..

If e.CommandSource="AddNewRow" Then
  'Add New Row to GridView.
End IF

在此按钮之外添加此按钮网格.当您单击添加按钮，然后将gridview行存储到另一个数据表中时，绑定时在底部添加一个空行.像这样:

Add this button outside of grid. when u''ll click on add button then store gridview rows into some another datatable and when bind that then add one empty row in the bottom. like this :

protected void addnew_Click(object sender, ImageClickEventArgs e)
    {
        grdMain.DataSource = FillDataTable(grdMain.Rows.Count + 1, "ADD", 0);
        grdMain.DataBind();
    }

public DataTable FillDataTable(int _rowCount, string _type, int _id)
    {
        DataTable _dtBands = ((DataTable)ViewState["item"]).Clone();

        DataRow row;
        if (_type == "ADD")
        {
            for (int i = 0; i < grdMain.Rows.Count; i++)
            {
                row = _dtBands.NewRow();
                row["Item"] = ((DropDownList)grdMain.Rows[i].FindControl("ddlItemName")).SelectedValue.ToString();
                row["Item_id"] = ((HiddenField)grdMain.Rows[i].FindControl("hdnitemid")).Value;
                
                _dtBands.Rows.Add(row);
            }

            row = _dtBands.NewRow();
            row["Item"] = "";
            row["Item_Id"] = "";
            
            _dtBands.Rows.Add(row);
        }
        else if (_type == "REMOVE")
        {
            for (int i = 0; i < grdMain.Rows.Count; i++)
            {
                if (i + 1 != _id)
                {
                    row = _dtBands.NewRow();

                    row["Item"] = ((DropDownList)grdMain.Rows[i].FindControl("ddlItemName")).SelectedValue.ToString();
                    row["item_id"] = ((HiddenField)grdMain.Rows[i].FindControl("hdnitemid")).Value;
                    
                    _dtBands.Rows.Add(row);
                }
            }
        }
        else
        {
            for (int i = 0; i < grdMain.Rows.Count; i++)
            {
                
                    row = _dtBands.NewRow();

                    row["Item"] = ((DropDownList)grdMain.Rows[i].FindControl("ddlItemName")).SelectedValue.ToString();
                    row["Item_Id"] = ((HiddenField)grdMain.Rows[i].FindControl("hdnitemid")).Value;
                  
                    _dtBands.Rows.Add(row);
           }
        }
        return _dtBands;
    }

使用这个可以做到这一点.

}

在Gridview的 RowCommand 事件上.
