问题描述
嗨
我正在处理转发器中的更新，但它无法正常工作，我的编码就是这样......
Hi I am working on update in repeater,but Its not working,My coding is this......
<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
<HeaderTemplate>
<table>
<tr>
<th>FEEDBACK</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "feedback")%>'></asp:TextBox></td>
<td> <asp:LinkButton ID="btnaprove" Runat="server" CommandName="Approve" CommandArgument='<%#DataBinder.Eval(Container.DataItem,"feedback") %>'>Approve</asp:LinkButton></td>
<td> <asp:LinkButton ID="btnupdate" Runat="server" CommandName="Update" CommandArgument='<%#DataBinder.Eval(Container.DataItem,"feedback") %>'>Update</asp:LinkButton></td>
<td> <asp:LinkButton ID="btndelete" Runat="server" CommandName="Delete" CommandArgument='<%#DataBinder.Eval(Container.DataItem,"feedback") %>'>Delete</asp:LinkButton></td>
</td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
Default.cs页面......
Default.cs page...
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "Update")
{
string str1 = ((TextBox)e.Item.FindControl("TextBox1")).Text;
cmd = new SqlCommand("update Table1 set feedback=@feedback where status='true'", con);
cmd.Parameters.AddWithValue("@feedback", str1);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
bind();
}
}
private void bind()
{
da = new SqlDataAdapter("select feedback from Table1", con);
DataSet ds = new DataSet();
da.Fill(ds);
Repeater1.DataSource = ds;
Repeater1.DataBind();
}
}推荐答案
protected void Page_Load(object sender, EventArgs e)
{
if(!page.ispostback)
{
Bind();
}
}
Public Void Bind()
{
da = new SqlDataAdapter("select feedback from Table1", con);
DataSet ds = new DataSet();
da.Fill(ds);
Repeater1.DataSource = ds;
Repeater1.DataBind();
}
和在Item_command之后你做了 -
and after Item_command as u did-
protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
if (e.CommandName == "Update")
{
string str1 = ((TextBox)e.Item.FindControl("TextBox1")).Text;
cmd = new SqlCommand("update Table1 set feedback=@feedback where status='true'", con);
cmd.Parameters.AddWithValue("@feedback", str1);
con.Open();
cmd.ExecuteNonQuery();
con.Close();
Bind();
}
}
