Question

我在ASP.NET Web应用程序中有一个GridView，其中我在每行中添加了按钮：

<asp:GridView ID="gridviewdatadosen" runat="server" AutoGenerateColumns="False" CssClass="table table-striped table-bordered table-hover" OnRowDataBound="gridviewdatadosen_RowDataBound" OnSelectedIndexChanged="gridviewdatadosen_SelectedIndexChanged" OnRowCommand="gridviewdatadosen_RowCommand">
    <Columns>
        <asp:BoundField DataField="NIK" HeaderText="NIK" SortExpression="NIK"></asp:BoundField>
        <asp:BoundField DataField="NIDN" HeaderText="NIDN" SortExpression="NIDN"></asp:BoundField>
        <asp:BoundField DataField="NAMA" HeaderText="NAMA" SortExpression="NAMA"></asp:BoundField>
        <asp:BoundField DataField="Alamat" HeaderText="Alamat" SortExpression="Alamat"></asp:BoundField>
        <asp:TemplateField ShowHeader="false">
            <ItemTemplate>
                <asp:Button ID="btnstatus" runat="server" Text="Aktif" CssClass="btn btn-primary" CommandName="aktifasi"  CommandArgument='<%# Eval("NIK") %>'/>
            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

我在服务器端填写datagridview。我填写了数据库中的数据。

                DataTable dt = new DataTable();
                DataTable dt1 = new DataTable();
                SqlConnection conn = new SqlConnection(@"Data Source=localhost;Initial Catalog=SKRIPSI;User ID=sa;Password=sa");
                conn.Open();
                string ngisi = "SELECT [nik] as 'NIK' , [nidn] as 'NIDN', [nama] as 'NAMA', [alamat] as 'Alamat' FROM [dosen]";
                SqlCommand comm = new SqlCommand(ngisi, conn);
                dt.Load(comm.ExecuteReader());
                conn.Close();
                gridviewdatadosen.DataSource = dt;
                gridviewdatadosen.DataBind();
                int tmp = dt.Rows.Count;

在填写datagridview之后，我想通过选择id和状态为dosen来检查他是否处于活动状态。

                conn.Open();
                string check = "SELECT nik, status FROM [dosen]";
                comm = new SqlCommand(check, conn);
                dt1.Load(comm.ExecuteReader());
                conn.Close();

我尝试更改按钮上的现有文字，但没有成功。

                        for (int i = 0; i < tmp; i++)
                    {
                        if (dt1.Rows[i][1].ToString() == "Aktif")//check the dosen aktif or not
                        {
                            for (int j = 0; j < tmp; j++)
                            {
                                if (dt.Rows[j][0].ToString() == dt1.Rows[i][0].ToString())// check nik where status = 'Aktif'
                                {
                                    // I want to change the button in each row. if he 'Aktif' then the text in button will change to be 'aktif'
                                    //do not know what to do
                                }
                            }
                        }
                    }

我想更改每行中的按钮。如果他'Aktif'那么按钮中的文字将变为'aktif'。帮我解决这个问题。对不起，如果我的英语或我的解释很糟糕。谢谢

您可以循环所有行，找到按钮并根据dt1

中的值更改文本

foreach (GridViewRow row in GridView1.Rows)
{
    //find the button in the row with findcontrol and cast back to a button
    Button button = row.FindControl("btnstatus") as Button;

    //check dt1 and set button text
    button.Text = "Active";
}

或者您可以使用OnRowDataBound事件在GridView数据绑定上执行相同的操作。

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        //find the button in the row with findcontrol and cast back to a button
        Button button = e.Row.FindControl("btnstatus") as Button;

        //check dt1 and set button text
        button.Text = "Active";
    }
}

Gridview在数据绑定后更改按钮列中的文本
