    copied!<p>I tried to download a file from sharepoint. But after I download this file, I can't click on other buttons. What is wrong with my coding?</p> <p><strong>This is my first way.</strong></p> <blockquote> <pre><code> Response.AppendHeader("content-disposition", "attachment; filename= " + fileName); Response.ContentType = "text/plain"; Response.WriteFile(Server.MapPath("~/" + fileName)); Response.End(); </code></pre> </blockquote> <p><strong>This is my second way</strong></p> <blockquote> <pre><code> byte[] bytes = System.IO.File.ReadAllBytes("D:\\" + fileName); Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("Content-Type", "application/octet-stream"); Response.AddHeader("Content-Length", bytes.Length.ToString()); Response.AddHeader("content-disposition", "attachment; filename= " + fileName); Response.BinaryWrite(bytes); Response.Flush(); Response.End(); </code></pre> </blockquote> <p>I even comment Response.End() but still the same result.</p> <p>Is there any other way I should tried?</p> <p>Any help would be really appreciated. In fact, I posted this question a few days ago, but only one gave me my second way to try but it is still not working.</p> <p>Thanks.</p> <p><strong>UPDATE</strong></p> <p>Here is my GridView under GridView.</p> <pre><code> &lt;asp:GridView ID="gvGiro" Width="100%" runat="server" GridLines="Both" AllowPaging="false" CssClass="form-table" ShowHeader="false" AllowSorting="false" AutoGenerateColumns="false" OnRowDataBound="gvGiro_RowDataBound"&gt; &lt;Columns&gt; &lt;asp:TemplateField ItemStyle-Width="20%" ItemStyle-HorizontalAlign="Center"&gt; &lt;ItemTemplate&gt; &lt;asp:Label ID="lblValueDate" Text='&lt;%# getDate(Eval("ValueDate")) %&gt;' runat="server" /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField&gt; &lt;ItemTemplate&gt; &lt;asp:GridView ID="gvDetail" runat="server" AllowPaging="false" AllowSorting="false" CssClass="list-table border" HeaderStyle-CssClass="header" AutoGenerateColumns="false"&gt; &lt;Columns&gt; &lt;asp:TemplateField HeaderText="Sequence Number" ItemStyle-HorizontalAlign="Left" ItemStyle-Width="30%" &gt; &lt;ItemTemplate&gt; &lt;%#((DataRowView)Container.DataItem)["MessageSeqNbr"] %&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Total Number of Debit Transaction" ItemStyle-HorizontalAlign="Left" HeaderStyle-HorizontalAlign="Center"&gt; &lt;ItemTemplate&gt; &lt;%#((DataRowView)Container.DataItem)["TotalDebitNbr"] %&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Status" ItemStyle-HorizontalAlign="Left" ItemStyle-Width="25%" HeaderStyle-HorizontalAlign="Center"&gt; &lt;ItemTemplate&gt; &lt;%#((DataRowView)Container.DataItem)["CodeDesc"] %&gt; &lt;asp:HiddenField ID="hidCode" runat="server" Value='&lt;%#((DataRowView)Container.DataItem)["Code"] %&gt;' /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:TemplateField HeaderText="Action" ItemStyle-HorizontalAlign="Center" ItemStyle-Width="10%" HeaderStyle-HorizontalAlign="Center"&gt; &lt;ItemTemplate&gt; &lt;asp:Button ID="btnDownload" runat="server" CssClass="button submit" Text="Download" CommandName="download" OnCommand="onCmd" CommandArgument='&lt;%#Eval("Id") %&gt;' Width="80px"/&gt; &lt;asp:Button ID="btnUnbatch" runat="server" CssClass="button generic" Text="Un-Batch" CommandName="unbatch" OnCommand="onCmd" CommandArgument='&lt;%#Eval("Id") %&gt;' Width="80px"/&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt; </code></pre> <p>Here is my cs file</p> <pre><code> protected void gvGiro_RowDataBound(object sender, GridViewRowEventArgs e) { GridView gr; if (e.Row.RowType == DataControlRowType.DataRow) { gr = (GridView) e.Row.FindControl("gvDetail"); using (class2 ct2= new Class2()) { Label lblValueDate = (Label)e.Row.FindControl("lblValueDate"); DateTime dt= DateTime.MinValue; DataSet ds= ct2.GetData(dt); gr.DataSource = ds; gr.DataBind(); } } } protected void onCmd(object sender, CommandEventArgs e) { string id; switch (e.CommandName) { case "unbatch": id= e.CommandArgument.ToString(); Unbatch(id); break; case"download": id= e.CommandArgument.ToString(); Download(id); break; default: break; } } protected void Download(string id) { // to do - substitute all hard-code guid Guid batchId = new Guid(id); string fileName = ""; Class1 ct = new Class1(); { if (!ct.FileExists(batchId , ref fileName)) { byte[] bytes = System.IO.File.ReadAllBytes("D:\\" + fileName); Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("Content-Type", "application/octet-stream"); Response.AddHeader("Content-Length", bytes.Length.ToString()); Response.AddHeader("content-disposition", "attachment; filename= " + fileName); Response.BinaryWrite(bytes); Response.Flush(); Response.End(); } </code></pre>
