  • Database Schema Managing Framework/Library

    - by Karol Kolenda
    I'm looking for any database framework/library for .net which will act as a unified layer between an application and databases. Please note that I'm not interested in querying/updating data (there is plenty of DALs for that) but rather a framework which allows me to manage table schemas and indexes in a managed fashion (without using database specific SQL). I'm particularly interested in a library which supports Oracle, SQL Server and PostreSQL.

  • String literals vs constants for Session[...] dictionary keys

    - by FreshCode
    Session[Constant] vs Session["String Literal"] Performance I'm retrieving user-specific data like ViewData["CartItems"] = Session["CartItems"]; with a string literal for keys on every request. Should I be using constants for this? If yes, how should I go about implementing frequently used string literals and will it significantly affect performance on a high-traffic site? Related question does not address ASP.NET MVC or Session.

  • how close to excel ergonimics can you make jqgrid

    - by oo
    I have been looking through [this jqgrid documentation][1] and see the example: i wanted to see how close you can get to data entry that is close to excel like moving arrows keys changes selection supporting Copy and paste from one cell to another column fills for a particular value. Is this asking to much for the web? If its not possible, are there other third party asp.net mvc components that do have these capabilities.

  • GridView paging inside an UpdatePanel or PlaceHolder components

    - by John
    Hello, I'm new to ASP.NET. Im developing ASP.NET C# web form which creating GridView components dynamically and filling them using the data received from my webservice. I'm creating these GridView components programmatically in server-side (cs file)- it has to be flexible - 1 GridView and sometimes 10 GridView components. The problem occurs when I'm trying to add pagination - whenever the user clicks the "next" page, the whole page is getting refreshed because of a postBack and I'm loosing all my data and the page returns Blank/Empty. I used PlaceHolder to hold the GridView components, while searching for a solution, I found UpdatePanel as a better alternative - as far as I understand the page can be partially refreshed - which means that only the UpdatePanel has to be refreshed...but it doesn't work. The following code sample is my TEST, the UpdatePanel is the only component initiated in the client side (aspx page), the rest initiated programmatically in CS. how can I solve the issue described above? Why does the whole page is getting refreshed and I'm loosing my data? can you recommend another way? can provide me with any code sample? If I'm not rebuilding the GridView, it doesn't work... Here is my Default.aspx.cs: public partial class TestAjaxForm : System.Web.UI.Page { DataTable table; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) bindGridView(); } public void bindGridView() { GridView gridView1 = new GridView(); gridView1.AutoGenerateColumns = true; gridView1.PageSize = 2; gridView1.AllowPaging = true; gridView1.PagerSettings.Mode = PagerButtons.Numeric; gridView1.PagerSettings.Position = PagerPosition.Bottom; gridView1.PagerSettings.PageButtonCount = 10; gridView1.PageIndexChanging += new GridViewPageEventHandler(this.GridView1_PageIndexChanging); table = new DataTable(); table.Columns.Add("FirstName"); table.Columns.Add("LastName"); DataRow row = table.NewRow(); row["FirstName"] = "John"; row["LastName"] = "Johnoson"; table.Rows.Add(row); row = table.NewRow(); row["FirstName"] = "Johnny"; row["LastName"] = "Marley"; table.Rows.Add(row); row = table.NewRow(); row["FirstName"] = "Kate"; row["LastName"] = "Li"; table.Rows.Add(row); panel.ContentTemplateContainer.Controls.Add(gridView1); gridView1.DataSource = table; gridView1.DataBind(); } protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e) { GridView gridView1 = (GridView)sender; gridView1.PageIndex = e.NewPageIndex; gridView1.DataSource = table; gridView1.DataBind(); } } Please help me, Thank you.

  • HTTP HEAD Request and System.Web.Mvc.FileResult

    - by mnero0429
    I'm using BITS to make requests to a ASP.NET MVC controller method named Source that returns a FileResult. I know the type FilePathResult uses HttpResponse.TransmitFile, but I don't know if HttpResponse.TransmitFile actually writes the file to the response stream regardless of the request type. My question is, does FileResult only include the header information on HEAD requests, or does it transmit the file regardless of the request type? Or, do I have to account for HEAD requests myself?
