为什么单元格内部的按钮"RowDataBound"没有触发事件点击？

Question

我正在实现一个网格视图，每个单元格内都有按钮。但是我不明白为什么网格视图上的单元格内的按钮没有触发。我使用网格视图 RowDataBound 和 RowCommand 来检查按钮是否触发。我还在网格视图外创建了一个按钮，但它按预期工作。我真的不明白为什么网格视图单元格上的按钮在单击后没有触发。

在代码隐藏上生成网格视图。

DataTable dataTable = new DataTable();
dataTable.Columns.AddRange(new DataColumn[32]
{
            new DataColumn("Month"),
            new DataColumn("Day1"),
            new DataColumn("Day2"),
            new DataColumn("Day3"),
            new DataColumn("Day4"),
            new DataColumn("Day5"),
            new DataColumn("Day6"),
            new DataColumn("Day7"),
            new DataColumn("Day8"),
            new DataColumn("Day9"),
            new DataColumn("Day10"),
            new DataColumn("Day11"),
            new DataColumn("Day12"),
            new DataColumn("Day13"),
            new DataColumn("Day14"),
            new DataColumn("Day15"),
            new DataColumn("Day16"),
            new DataColumn("Day17"),
            new DataColumn("Day18"),
            new DataColumn("Day19"),
            new DataColumn("Day20"),
            new DataColumn("Day21"),
            new DataColumn("Day22"),
            new DataColumn("Day23"),
            new DataColumn("Day24"),
            new DataColumn("Day25"),
            new DataColumn("Day26"),
            new DataColumn("Day27"),
            new DataColumn("Day28"),
            new DataColumn("Day29"),
            new DataColumn("Day30"),
            new DataColumn("Day31")
});
DataRow dataRow;
var months = new string[] { "JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP", "OCT", "NOV", "DEC" };
for (int i = 0; i < 12; i++)
{
    dataRow = dataTable.NewRow();
    dataRow["Month"] = months[i];
    for (int j = 0; j < 30; j++)
    {
    }
    dataTable.Rows.Add(dataRow);
}
GridView.DataSource = dataTable;
GridView.DataBind();
protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        LoadDataSources();
    }
}

在单元格上呈现按钮。

protected void GridViewPricing_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        for (int i = 1; i <= 31; i++)
        {
            var button = new Button();
            button.ID = string.Format("{0}", i);
            button.Attributes.Add("style", "display:block; padding:4px; width:100%; height:100%;");
            button.CommandName = "ButtonCell";
            button.CommandArgument = "ButtonCell";
            e.Row.Cells[i].Controls.Add(button);
        }
    }
}

测试单击按钮后是否触发。

protected void ButtonCell_Click(object sender, EventArgs e)
{
    Response.Write("Button Click");
}
protected void GridViewPricing_RowCommand(object sender, GridViewCommandEventArgs e)
{
    Response.Write("Button Click");
}

这是供查看的。

Answer 1

试试这个：

在

元素的结束标记之前添加按钮columns

<asp:BoundField DataField="Day31" HeaderText="31" />
  <asp:ButtonField ButtonType="Button"  CommandName="ButtonCommandName" HeaderText="Buttons" 
     ShowHeader="True" Text="Click Me" ItemStyle-Width="30px" />
</Columns>

在您的GridView_RowCommand

protected void GridViewPricing_RowCommand(object sender, GridViewCommandEventArgs e)
{
     int index = Convert.ToInt32(e.CommandArgument);
      GridViewRow gvRow = GridViewPricing.Rows[index];
     if (e.CommandName == "ButtonCommandName")
      {
          //Your Code here something like 
           gvRow.Cells[0].Text
      }
}
