.Net-在运行时将ASP按钮动态添加到ASPX中的表中

Question

我需要在运行时在aspx 中的表中添加按钮

table.Append("<table border='1' class='table table-striped' width='450px'>");
table.Append("<tr><th>Facilities</th><th>Size</th><th>InterestRate</th><th>View in Doc</th>");
table.Append("</tr>");
if (dr.HasRows)
{
while (dr.Read())
{
table.Append("<tr >");
table.Append("<td>" + dr[0] + "</td>");
table.Append("<td>" + dr[1] + "</td>");
table.Append("<td>" + dr[2] + "</td>");
table.Append("<td>" + <asp:Button ID = 'btnOpenDoc' runat = 'server' CssClass = 'button rounded' Width = '200px' Text = 'Open Document' OnClick = 'RunPowerShellScript_OnClick()'/> + "</td>");
table.Append("</tr>");
}
}

我对这条线有意见：

table.Append("<td>" + <asp:Button ID = 'btnOpenDoc' runat = 'server' CssClass = 'button rounded' Width = '200px' Text = 'Open Document' OnClick = 'RunPowerShellScript_OnClick()'/> + "</td>");

Answer 1

不能通过串联字符串来添加服务器控件。

试试这个，

伪码

<form id="form1" runat="server">
<div>
<asp:Table ID="table" runat="server">
<asp:TableRow>
<asp:TableCell>
</asp:TableCell>
</asp:TableRow>
</asp:Table>    
</div>
</form>

编码后

protected void Page_Load(object sender, EventArgs e)
{
Button btn = new Button()
{
ID = "btnOpenDoc",
CssClass = "button rounded",
Width = 200,
Text = "Open Document"
};
table.Rows[0].Cells[0].Controls.Add(btn);
btn.Click += RunPowerShellScript_OnClick;
}
protected void RunPowerShellScript_OnClick(object sender, EventArgs e)
{
}
