Question

gridview控件使用模版后在里面放置了个LINKBUTTON,要在后台实现点击这个LINKBUTTON后获取它的Text该怎么做

在后台根本就找不到它的ID号啊，而且LINKBUTTON的TEXT是每行都不一样的

Answer 1

先获取当前行的索引 int row = ((GridViewRow)((LinkButton)sender).NamingContainer).RowIndex;
LinkButton lbtn= (LinkButton )(gdvApply.Rows[row].Cells[那一列].FindControl("linkbutton的名称"));
string test=lbtn.Text;

Answer 2

楼主先确定在什么事件中查找，有很多方式，给出两种方式，请参考

.aspx
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False"
onrowcommand="GridView1_RowCommand">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" Text='<%# Eval("Name") %>'
CommandArgument='<%# Eval("Name") %>' ></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LinkButton2" runat="server" Text='<%# Eval("Name") %>' onclick="LinkButton2_Click" ></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

.aspx.cs
public partial class GridViewDemo : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
{
BindData();
}
}

private void BindData()
{
List<User> list = new List<User>();
list.Add(new User { Id = 1, Name = "aa" });
list.Add(new User { Id = 2, Name = "bb" });
list.Add(new User { Id = 3, Name = "cc" });
list.Add(new User { Id = 4, Name = "dd" });
GridView1.DataSource = list;
GridView1.DataBind();
}

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
string text = (string)e.CommandArgument;
if (!string.IsNullOrEmpty(text))
{
lblMsg.Text = text;
}
}

protected void LinkButton2_Click(object sender, EventArgs e)
{
LinkButton btn = sender as LinkButton;
lblMsg.Text = btn.Text;
}
}

public class User
{
public int Id { get; set; }
public string Name { get; set; }
}
<asp:Literal ID="lblMsg" runat="server"></asp:Literal>

Answer 3

FindControl试试
