Repeater nested datalist

Here we will briefly describe the key part of implementation:

1. Repeater binding; 2. It is very easy to bind datalistrepeater to the itemdatabound event of repeater. Net. The key lies in the nested datalist. The following is the itemdatabound event of repeater:

 

 protected void rptEmoteClass_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            DataList dl = (DataList)e.Item.FindControl("dlEmote");
            DataRowView drview = (DataRowView)e.Item.DataItem;
int _classId = Convert.ToInt32(drview["classid"]);

using (NT.Data.SqlServer.CmsTuyuOperator tuyu = new NT.Data.SqlServer.CmsTuyuOperator())
            {
                DataSet ds = tuyu.ListEmoteAlbum(_classId, 16);
if (ds != null)
                {
                    dl.DataSource = ds.Tables[0].DefaultView;
                    dl.DataBind();
                }
            }
        }
    }

 

 

The key is to obtain the classid bound to datalist:

 

 DataRowView drview = (DataRowView)e.Item.DataItem;             int _classId = Convert.ToInt32(drview["classid"]);

 

 

 

Others are the binding statement !!

This method can then be extended to datalist nested datalist, repeater nested repeater, or even third-level nesting !!
