如何把在ASP.NET GridView中的标头中的按钮？ [英] How to put a button in a header of ASP.NET gridview?

问题描述

所有我想要做的就是把一个asp：按钮在GridView的标题中。
比方说，你有3列的网格视图 - ID，姓名，家庭。因此，而不是一个标题[ID，姓名，家庭]我希望它是[ID，名称，ASP：按钮] - 使按键都会有它的过程中的作用

All I want to do is to put an asp:button in the header of a gridview. Let's say you have a grid view with 3 columns - id, name, family. So, instead of a header [id, name, family] i want it to be [id, name, asp:button] - so the button will have it's action of course.

谢谢，
罗马。

Thanks, Roman.

推荐答案

你需要采取的方法是使所需的GridView列模板字段。当你使用模板字段，你可以坚持任何asp.net控制到GridView控件（标题，项目，页脚等）的各个主要部分。我没有测试过这一点，但在主要的它看起来像这样：

The approach you'll need to take is to make that desired GridView column a template field. When you use template fields you can stick any asp.net controls into each main section of the gridview control (header, item, footer, etc). I haven't tested this but in principal it looks like this:

        <asp:GridView ID="Gridview1" runat="server">
        <Columns>
            <asp:BoundField DataField="yourDbColumnName" HeaderText="id" />
            <asp:BoundField DataField="yourDbColumnName" HeaderText="name" />
            <asp:TemplateField>
                <HeaderTemplate>
                    <asp:Button runat="server" ID="btnFamily" CommandName="FamilyClicked" />
                </HeaderTemplate>
                <ItemTemplate>
                    <asp:Literal runat="server" ID="litFamily" Text='<%# EVAL("YourDbColumnValue") %>'></asp:Literal>
                </ItemTemplate>
            </asp:TemplateField>
        </Columns>
    </asp:GridView>

要捕获你的按钮的单击事件，并用它做什么，你需要利用GridView的RowCommand事件（这里是一个起点 - 又未经测试）：

To "capture" your button's click event and do something with it you need to utilize the GridView's RowCommand event (here's a starting point - again untested):

    Protected Sub Gridview1_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles Gridview1.RowCommand
    If e.CommandName = "FamilyClicked" Then
        ' they clicked by grid view header's asp:button control...
        Response.Write("TEST")
    End If
End Sub

在这里神奇的是在你的按钮的CommandName属性的分配（在这种情况下，我将其设置为FamilyClicked但它可以是任何你想要的）。

The magic here is in the assignment of your button's CommandName property (in this case I set it to "FamilyClicked" but it can be anything you want).
