Telerik Radgrid GridDataItem.DataItem在更新时为空(OnUpdateCommand处理程序) [英] Telerik Radgrid GridDataItem.DataItem is empty when updating (OnUpdateCommand handler)

问题描述

在RadGrid上处理OnUpdateCommand事件时，DataItem为null.

When handling the OnUpdateCommand event on a RadGrid the DataItem is null.

我认为这也将代表该行所代表的数据项.

I thought that this would also represent the data item being represented by the row.

Radgrid由IList填充，并且在处理程序中，代码如下所示.

The Radgrid is populated from an IList and in the handler the code looks like this...

protected void rgAllocatedClients_UpdateCommand(object sender, GridCommandEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        var gridDataItem = e.Item as GridDataItem;
        var client= gridDataItem .DataItem as Client;
        ....
        ....

在处理ItemDataBound事件时有效，但在处理UpdateCommand事件时找不到.我真的需要这个，因为在我的Client类中，是我要为其处理更新的行的ID.

This works find when handling the ItemDataBound event but not when handling the UpdateCommand event. I really need this as in my Client class is the Id of the row I want to handle the update for.

谢谢

推荐答案

尝试使用GridEditableItem

Try this by using GridEditableItem

 protected void grdContacts_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {

        string idEditing = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["Id"].ToString();
        GridEditableItem editedItem = e.Item as GridEditableItem;
        Hashtable newValues = new Hashtable();
// ur code
}
