Download within Grid Command and Command Handler of file
Hey guys,
a few weeks ago, we bought some licences in our company for ext.net and now there comes up my first question :-)
I already looked up other threads here to find the answer but nothing helped for me.
the problem is the following:
i have a grid Panel that lists me the files of a folder with it's name, size, description etc. no problem. Now for each "file-row", i have a download "Button", which should download the file by clicking it:
Code:
<body>
<ext:ResourceManager ID="ResourceManager1" runat="server" />
<form runat="server">
<ext:GridPanel
ID="folderContentGrid"
runat="server"
StripeRows="true"
Title="Folder content"
Layout="FitLayout"
Height="500px"
AutoScroll="true"
>
<Store>
<ext:Store runat="server">
<Reader>
<ext:ArrayReader>
<Fields>
<ext:RecordField Name="fileIcon" Type="String" />
<ext:RecordField Name="fileName" Type="String" />
<ext:RecordField Name="fileFullname" Type="String" />
<ext:RecordField Name="fileSize" Type="Int" />
<ext:RecordField Name="uploadDate" Type="Date" />
<ext:RecordField Name="description" Type="String" />
</Fields>
</ext:ArrayReader>
</Reader>
</ext:Store>
</Store>
<ColumnModel runat="server">
<Columns>
<ext:RowNumbererColumn />
<ext:Column DataIndex="fileIcon" Header="Icon" Width="260px"/>
<ext:Column DataIndex="fileName" Header="Name" Width="260px"/>
<ext:Column DataIndex="fileFullname" Header="Fullname" Width="260px" Hidden="true"/>
<ext:NumberColumn DataIndex="fileSize" Header="Size" Width="260px"/>
<ext:DateColumn DataIndex="uploadDate" Header="UploadDate" Width="260px"/>
<ext:Column DataIndex="description" Header="Beschreibung" Width="260px"/>
<ext:CommandColumn Header="Download" Width="60">
<Commands>
<ext:GridCommand Icon="DiskDownload" CommandName="download">
<ToolTip Text="Download" />
</ext:GridCommand>
</Commands>
</ext:CommandColumn>
</Columns>
</ColumnModel>
<SelectionModel>
<ext:RowSelectionModel ID="RowModel" runat="server" SingleSelect="true" />
</SelectionModel>
<Listeners>
<Command Handler="Ext.net.DirectMethods.downloadFile(record.data.fileFullname);"/>
</Listeners>
</ext:GridPanel>
</form>
</body>
the DirectMethod "downloadFile" looks like that, i just tested it now for an Excel document, i know i will need a switch case for defining the Mime type of the document:
Code:
[DirectMethod]
public void downloadFile(string filepath)
{
try
{
// filepath is now: C:/user/testuser/test.xls
string type = "application/msexcel";
String FilePath = filepath.Replace("/", "\\");
String FileName = FilePath.Substring(FilePath.LastIndexOf("\\") + 1);
// FilePath is now: C:\users\testuser\test.xls"
// FileName is now: test.xls
Response.ClearContent();
Response.Clear();
Response.Buffer = true;
Response.ContentType = type;
Response.AddHeader("Content-Type", type);
Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";");
Response.TransmitFile(FilePath);
Response.Flush();
Response.End();
}
catch (Exception ex)
{
X.Msg.Alert("error", "data not found").Show();
}
}
if i try that code, i get the error "BADRESPONSE: illegal character" .. i read that i need an IsUpload="true"..somewhere.. but could not find the right place for it by using a command handler for a Grid command.
I hope you can help me out here :-)
Best regards,
novacp.
