我的页面上有一个网格，我需要刷新 gridview 添加和删除新记录，但它不是？
这是代码：
将行添加到 GridView：
private void AddClientToGrid()
{
int clientID = int.Parse(ddlClient.SelectedValue);
int clientTypeID = int.Parse(ddlClientType.SelectedValue);
ClientsAllCDO client = new ClientsBL().ClientsAllSelectByIDAndClientTypeID(clientID, clientTypeID);
List<ClientsAllCDO> clientList = new List<ClientsAllCDO>();
clientList = GetClientsFromGrid();
clientList.Add(client);
gvClient.DataSource = clientList;
gvClient.DataBind();
}
删除代码：
protected void btnDeleteClient_Click(object sender, EventArgs e)
{
LinkButton btnDeleteClient = sender as LinkButton;
int rowIndex = int.Parse(btnDeleteClient.Attributes["RowIndex"]);
if (Request.QueryString["BailiffID"] == null)
{
gvClient.DeleteRow(rowIndex);
}
else
{
int bailiffID = int.Parse(FormCrypto.Decrypt(Request.QueryString["BailiffID"]));
GridViewRow gvRow = gvClient.Rows[rowIndex];
int clientTypeID = int.Parse(((Label)gvRow.FindControl("lblClientTypeID")).Text);
int clientID = int.Parse(((Label)gvRow.FindControl("lblClientID")).Text);
gvClient.DeleteRow(rowIndex);
new BailiffClientsBL().BailiffClientDelete(clientID, bailiffID, clientTypeID);
}
}
多谢...
您需要将网格重新绑定到数据源：
//delete row from the database
GridView1.DataSource = SomeDataRetrievalMethod(); //retrieve the data from the database
GridView1.DataBind();
