推荐答案
我的devexpress上有点生疏，但在你的网格控件中，我认为你应该指定一个网格视图。从该网格视图中，为了从Id列中获取Id，您可以这样做。
I'm a bit rusty on my devexpress but in your gridcontrol i think you should be specifying a grid view. From that grid view, in order to get the Id from an Id column you would do.
devExpressGridView.GetFocusedRowCellValue("Id")
这将假设您的网格列包含标签为Id的列。因此，如果您的列标记为Index，那么您将使用Index切换Id。
This would assume that your grid's columns contain a column with label of Id. So if your column is labeled Index, then you would switch out Id with Index.
protected void btnEditItem_Click（object sender，EventArgs e）
{
试试
{
LinkButton btn =（LinkButton）发件人;
var gvr =（DevExpress.Web.ASPxGridView.GridViewDataItemTemplateContainer）btn.NamingContainer;
var trt = gvr.ItemIndex;
}
catch（Exception ex）
{
}
}
protected void btnEditItem_Click(object sender, EventArgs e)
{
try
{
LinkButton btn = (LinkButton)sender;
var gvr = (DevExpress.Web.ASPxGridView.GridViewDataItemTemplateContainer)btn.NamingContainer;
var trt = gvr.ItemIndex;
}
catch (Exception ex)
{
}
}
