我对C#和asp.net很陌生,如果这是一个非常愚蠢的问题,请道歉。
我正在使用网格视图来显示数据库中的大量记录。
每一行都有一个编辑按钮。单击该按钮时,我希望将ID传递回我的.cs文件中的函数。如何将rowID绑定到Button字段?
我已经厌倦了使用超级链接,但这似乎不起作用,因为我回发到已经在URL上已经有Permanter的同一页面。
asp.net
<asp:GridView ID="gvAddresses" runat="server" onrowcommand="Edit_Row">
<Columns>
<asp:ButtonField runat="server" ButtonType="Button" Text="Edit">
</Columns>
</asp:GridView>
C#
int ImplantID = Convert.ToInt32(Request.QueryString["ImplantID"]);
Session.Add("ImplantID", ImplantID);
List<GetImplantDetails> DataObject = ImplantDetails(ImplantID);
System.Data.DataSet DSImplant = new DataSet();
System.Data.DataTable DTImplant = new DataTable("Implant");
DSImplant.Tables.Add(DTImplant);
DataColumn ColPostCode = new DataColumn();
ColPostCode.ColumnName = "PostCode";
ColPostCode.DataType = typeof(string);
DTImplant.Columns.Add(ColPostCode);
DataColumn ColConsigneeName = new DataColumn();
ColConsigneeName.ColumnName = "Consignee Name";
ColConsigneeName.DataType = typeof(string);
DTImplant.Columns.Add(ColConsigneeName);
DataColumn ColIsPrimaryAddress = new DataColumn();
ColIsPrimaryAddress.ColumnName = "Primary";
ColIsPrimaryAddress.DataType = typeof(int);
DTImplant.Columns.Add(ColIsPrimaryAddress);
DataColumn ColImplantCustomerDetailsID = new DataColumn();
ColImplantCustomerDetailsID.ColumnName = "Implant ID";
ColImplantCustomerDetailsID.DataType = typeof(int);
DTImplant.Columns.Add(ColImplantCustomerDetailsID);
foreach (GetImplantDetails Object in DataObject)
{
DataRow DRImplant = DTImplant.NewRow();
DRImplant["PostCode"] = Object.GetPostCode();
DRImplant["Consignee Name"] = Object.GetConsigneeName();
DRImplant["Primary"] = Object.GetIsPrimaryAddress();
DRImplant["Implant ID"] = Object.GeTImplantCustomerDetailsID();
DTImplant.Rows.Add(DRImplant); <--- this is what I need to be added to the button
}
gvAddresses.DataSource = DTImplant;
gvAddresses.DataBind();
答案 0 :(得分:2)
在Edit_Row
方法中,您可以访问正在编辑的行的索引,如:
int rowIndex = (int)e.CommandArgument;
完成后,您可以直接访问该行并提取所需的任何值:
GridViewRow row = gvTest.Rows[rowIndex];
int implantId = Int32.Parse(string row.Cells[3].Text);
或者,您也可以将属性DataKeyNames="Implant ID"
添加到GridView并以这种方式访问ID:
int implantId = Int32.Parse(gvTest.DataKeys[rowIndex]["Implant ID"].ToString());
