Is it better to cache a dataset on the webserver OR use a XML file on a server and maintaining a structure in the XML file that we populate accordingly when required The dataset has 10 datatables and the site could have more than 50 users at once instance Is it better to use the XML file stored on a server or Cache the dataset on the webserver considering that the application runs on a web farm I have to cache the dataset for the users to come back again to the same page and enter new values in the dataset ( something like adding stuff to a basket )

Thanks

When I click a link, a grid should be visible. Its similar to tab controls but in tab controls the tabs will be horizontal, but I need it to be vertical. Like a tree view, when I click, Link1, underneath, a control will pop up which will have a grid. When I click Link2, another control should open up. Can you suggest me which control I can use for this? I have tried to describe but if not clear, I can try explaining again.

Thanks

I sort the datatable and hence store it in dataview. I use dataView.Sort. GridView.DataSource = SortedDataView; GridView.DataBind(); I get the sorted grid now. When I click edit, the sort goes off. So I try to store it in a cache Cache["AdminGrid"] = SortedDataView; Iam unable to retrieve it into a datatable again. DataTable dtData = (DataTable)Cache["AdminGrid"]; results in an error saying DataView cannot be converted into DataTable. Any help is appreciated.

Thanks

I know sorting can be done ascending/descending on a gridview. Can it be done on each page of the grid when paging also is enabled?

Thanks

That is not possible since ASP.Net folder consists of only App_GlobalResources, localresources, Data, Browsers and Theme. On a web application, am not able to add App_Code. On a web site, as you said, am able to. Where should I drop the global class files on the web application?

Thanks

When I developed the website, I had put the classes which needs to be accessed throughout the application in App_Code. Now when I develop a web application, I don't see App_Code folder. Am able to drop them in App_GlobalResources folder and it works but I read it is for the global resource files. What is the best practice and where should I drop the class files?

Thanks

On my local machine, when I try to access the .doc through browser, it takes me to the Fail.aspx and when I go through the application am able to access. The problem is with dll. On the remote server, I get the error. Please help.

Thanks

Sorry, I should have written that the Remote Server has .Net Framework installed and not visual studio.

Thanks

My aim is to block the .doc file access through Url. on IIS, I added a mapping to *.doc. This is a remote server that does not have dotnet installed. On my application, I put a class which includes ProcessRequest method. On the web.config, I have added <add verb="*" path="*.doc" type="DocNamespace.DocClass,DocDllName>; <add key="PathToRedirect" value="~/Fail.aspx>; I compiled this class to dll and put it on my bin folder. Error I find is "Could not load file or assembly DocDllNameor one of its dependencies. The system cannot find the file specified." I referred the below http://www.15seconds.com/issue/020417.htm[^] Please help. Thanks

I have a master page and there is a tree view control there and this is one of the treenodes. TreeNode _Del = new TreeNode(); _Del.Text = "Administrator"; _Del.NavigateUrl = "~\\Form1.aspx"; TreeNode _Del1 = new TreeNode(); _Del1.Text = "Manager"; _Del1.NavigateUrl = "~\\Form1.aspx"; There is a Form1 and the form1 has two panels. If treenode corresponding to _Del is clicked, panel1.visible=true, panel2.visible=false and if _Del1 is clicked, panel1.visible=false, panel2.visible=true Question: How do I get which treenode am clicking in the Form1? Is response.redirect querystring the only option? Please help and if the post is not clear, please mention. I can more clearly tell you.

This is the validator. * The javascript function is: function ValidateDelegFn() { if((document.getElementById('<%=checkbox1.ClientID%>').checked== false) { return(false);} else {return(true);} } From code behind, addDelegateImageButton.Attributes.Add("onclick", "ValidateDelegFn()"); Still, it gets into addDelegateImageButton_Click(object sender, ImageClickEventArgs e) function. How do I make it get into the addDelegateImageButton_Click function only if ValidateDelegFn returns true? Please help Thanks
