Question

我有一个网格，我一直试图在后面的代码中设置。到目前为止，一切都进展顺利，但是什么时候我去设置itemcommand事件或事件的任何事件，当我去点击命令或做一些应该导致触发事件的事情时，什么都没有结束。所以我想知道我对我的项目命令的声明到底出错了什么。您将在下面找到我的代码：

private void createRadGrid()
    {
        //create radgrid
        RadGrid rg = new RadGrid();
        rg.ID = "RadGridView";

        //setting the datasource and itemcommand event handler.
        rg.DataSourceID = "MachineDataSet";
        rg.ItemCommand += new GridCommandEventHandler(RadGridView_ItemCommand);

        rg.Width = 862;
        rg.CellSpacing = 2;
        rg.CellPadding = 4;
        rg.BorderWidth = 3;
        rg.BackColor = System.Drawing.Color.Transparent;
        rg.BorderColor = System.Drawing.Color.DarkGray;
        rg.ForeColor = System.Drawing.Color.Black;
        rg.ItemStyle.HorizontalAlign = HorizontalAlign.Center;
        rg.HeaderStyle.HorizontalAlign = HorizontalAlign.Center;
        rg.BorderStyle = BorderStyle.Ridge;
        rg.ShowStatusBar = true;

        rg.AllowPaging = true;
        rg.PageSize = 5;
        rg.PagerStyle.Mode = GridPagerMode.NextPrevAndNumeric;
        rg.AutoGenerateColumns = false;

        rg.MasterTableView.PageSize = 5;
        rg.MasterTableView.DataKeyNames = new string[] { "ID" };
        rg.MasterTableView.ClientDataKeyNames = new string[] { "ID" };
        rg.MasterTableView.AutoGenerateColumns = false;

        rg.ClientSettings.Resizing.AllowColumnResize = true;
        rg.ClientSettings.Resizing.EnableRealTimeResize = true;
        rg.ClientSettings.Resizing.ResizeGridOnColumnResize = true;

        GridBoundColumn boundColumn = new GridBoundColumn();
        boundColumn.DataField = "ID";
        boundColumn.HeaderText = "ID";
        boundColumn.UniqueName = "MachineID";
        boundColumn.Visible = false;
        rg.MasterTableView.Columns.Add(boundColumn);

        GridBoundColumn boundColumn1 = new GridBoundColumn();
        boundColumn1.DataField = "SiteName";
        boundColumn1.HeaderText ="Site Name";
        boundColumn1.Resizable = true;
        boundColumn1.ReadOnly = true;
        rg.MasterTableView.Columns.Add(boundColumn1);

        GridBoundColumn boundColumn2 = new GridBoundColumn();
        boundColumn2.DataField = "Name";
        boundColumn2.HeaderText = "Machine Name";
        boundColumn2.Resizable = true;
        boundColumn2.ReadOnly = true;
        rg.MasterTableView.Columns.Add(boundColumn2);

        GridBoundColumn boundColumn3 = new GridBoundColumn();
        boundColumn3.DataField = "MachineType";
        boundColumn3.HeaderText = "Machine Type";
        boundColumn3.Resizable = true;
        boundColumn3.ReadOnly = true;
        rg.MasterTableView.Columns.Add(boundColumn3);

        GridBoundColumn boundColumn4 = new GridBoundColumn();
        boundColumn4.DataField = "MachineModel";
        boundColumn4.HeaderText = "Machine Model";
        boundColumn4.Resizable = true;
        boundColumn4.ReadOnly = true;
        rg.MasterTableView.Columns.Add(boundColumn4);

        GridButtonColumn buttonColumn = new GridButtonColumn();
        buttonColumn.ButtonType = GridButtonColumnType.PushButton;
        buttonColumn.CommandName = "AssignNewValues";
        buttonColumn.Resizable = true;
        buttonColumn.Text = "Assign New Values";
        rg.MasterTableView.Columns.Add(buttonColumn);

        PlaceHolder_RadGridView.Controls.Add(rg);
    }

问题区域似乎在这一行

rg.ItemCommand += new GridCommandEventHandler(RadGridView_ItemCommand);

非常感谢任何帮助或建议。

Answer 1

尝试将 createRadGrid（）置于 page_init 或 page_load 事件中。如果你之后设置了事件，那可能就是它没有被解雇的原因。

希望这有任何帮助。

干杯。

Answer 2

尝试移动此行：

PlaceHolder_RadGridView.Controls.Add(rg);

此行之后的权利：

RadGrid rg = new RadGrid();
rg.ID = "RadGridView";

看看是否有所作为。

以编程方式设置itemcommand事件
