Sushil Mate 28-Jan-13 6:26am

what is that doubt?

Deenuji 28-Jan-13 6:28am

i have url on this link but when i click this link i want to open or view that clicked xml document?

Sushil Mate 28-Jan-13 6:30am

you will, you don't have to worry about it. windows has the association between .xml to internet explorer so whenever user clicks on that link it will open that XML document in IE.

Solution 2

If you want to open the file normally then you can use Response.Redirect(YourFilePath). And if you want to download the file then you can use the function below. Call the function in your RowCommand Event of GridView and pass the path of corresponding file. Try this:

ASP.NET

<!--This should be there in your aspx file inside gridview itemtemplate-->
<asp:LinkButton ID="lnkView" runat="server" Text="View Document" CommandName="View" CommandArgument='<%#EVal("URL")%>'/>

C#

protected void Gridview_RowCommand(Object sender, GridViewCommandEventArgs e)
{
   if(e.CommandName == "View")
   {
       DownloadFile(e.CommandArgument.ToString());
   }
}

public void DownloadFile(string FilePath)
{
    Response.Clear();
    Response.ContentType = @"application\octet-stream";
    System.IO.FileInfo file = new System.IO.FileInfo(Server.MapPath(FilePath));
    Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
    Response.AddHeader("Content-Length", file.Length.ToString());
    Response.ContentType = "application/octet-stream";
    Response.WriteFile(file.FullName);
    Response.Flush();
}

Hope it helps!

Deenuji 28-Jan-13 6:37am

for example i have link like C:\Users\FABS\Documents\Xml Search\upload\count.xml in gridview.....how can i pass this selected link to open through redirect??????

_Amy 28-Jan-13 6:41am

Pass it using CommandArgument property of LinkButton. Try my updated answer.. All the best.

Deenuji 28-Jan-13 6:46am

Error Creating Control -'System.Web.UI.WebControls.HyperLinkField' does not have a public property named 'CommandName' ....
I'm getting this error sir...

_Amy 28-Jan-13 6:48am

You should use LinkButton not HyperLink.. Check my answer carefully.

Deenuji 28-Jan-13 7:21am

Actually i can't find link button in that gridview....it have only hyperlink only....now what to do sir?

_Amy 28-Jan-13 7:25am

You need to change it to LinkButton. Try replacing your asp:HyperLink to asp:LinkButton. If you are still unable to do that then paste your HTML code here. I'll check that.

Deenuji 28-Jan-13 7:32am

now i'm trying with this coding

<asp:CommandField ShowSelectButton="True" />
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False"
ReadOnly="True" SortExpression="ID" />
<asp:HyperLinkField DataTextField="Result" DataNavigateUrlFields="Result" DataNavigateUrlFormatString="Show.aspx?Result={0}" Text="Result"
HeaderText="Link" />
<asp:TemplateField>
<itemtemplate>
<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Bind("Result") + Request.QueryString("type") %>'
Text="">

_Amy 28-Jan-13 7:36am

Add the following in your GridView:

<asp:TemplateField>
<itemtemplate>
<asp:LinkButton ID="lnkView" runat="server" Text="View Document" CommandName="View" CommandArgument='<%#EVal("Result")%>'/>

Deenuji 28-Jan-13 7:42am

After that what i do to select that particular link and view that file????

Deenuji 28-Jan-13 7:48am

Error is The name 'EVal' does not exist in the current context.....so what we declare the value for Eval???? thn whr v ve to declare this???

_Amy 28-Jan-13 8:30am

It's not EVal its Eval. Sorry I mistyped that word.
