new to this forum, and visual studio web development. Here is what I want to do: -From a webpage on my website, I would like to upload multiple photos to an sql database, but instead of having a container or field name for each photo, i would like to have multiple photos on one field, on each record.Then, I would like to display it back one record at a time, but with the capability of displaying all the pics from the one field holding the pics. Similar to the function in MS Access, where I can upload mutiple photos in one field and then display them back by just scrolling through them on the same record.
View 2 RepliesI am currently familiarizing myself to WebMatrix. I am interested in creating a webpage. I have installed all necessary programs. I have also created a webpage but when I try to run the program I get the following message:
URL Binding Failure Cannot start the website because admin privileges are required to bind to the hostname or port.
Recommendations: I thought I might do it manually. I went to the Site Panel, on the Main Page I then tried to select 'ASP.NET Web Pages Administration'. Clicking this and anything below it cause WebMatrix to crash. It also causes it to crash if I select run and not run with IE8 (no webpage is displayed even though i have a aspx page).
I have few textboxes and I want to search the text (partial search is also required) in the database and then show the result in a telerik grid. The grid has to be hidden initially and when I click the search button it should show up and display the results.

My Dropdownlist binds itself twice? How could it be happen, I've debugged but get no conclusion.
<asp:DropDownList ID="ddlTherapArea" runat="server" AppendDataBoundItems="True"
DataSourceID="sdsTherap" DataTextField="TherapAreaName" DataValueField="TherapAreaID"
Height="20px" Width="310px" ondatabinding="ddlTherapArea_DataBinding">

I have a Gridview set up so when a user clicks the various buttons it sorts the results. I have a couple problems. Right now the way i have the viewStates set up, it is only working when the buttons are clicked twice. I Was also wondering how to set up the viewstates so it binds properly when the editing and updating. I have read up on ViewStates and I am still a bit confused.

Scenario:
I am creating a custom gridview control which has a custom CheckBoxTemplateField column (deriving from TemplateField class). This template field column has custom Checkboxheadertemplate (implementing ITemplate) and CheckboxItemTemplate (also implementing ITemplate). In InstantiateIn method of both templates (header as well as Item template), I am adding a checkbox control which has Autopostback = true.
My requirement is:
I want to mark all the values in the binding column of datasource if checkbox in headertemplate is checked. I dont want to mark only rows visible on grid. I WANT TO MARK ALL ROWS IN DATASOURCE. I want to do this in _CheckedChanged event of checkbox in header template.
Problem I am facing: When I check/uncheck the checkbox in header, it postbacks. so in OnCheckedChanged event, gridview's datasource is null. Secondly, in any event of gridview, I could access only those rows of datasource for which corresponding rows are visible in gridview through Gridviewrow.DataItem property. But I want to set it for all rows in datasource.
I'm getting an error in Parallels Plesk for SQL Server database on restore the cause of which is a mystery to me. Here is the support ticket I sent my hosting company:
I'm in the process of restoring my databases and the first one restored just fine. The second one called ***** for *****.com failed with the following error:
Error: dbbackup failed: Unable to restore database 'alienreports' Not valid backup The media family on device C:WINDOWSTEMPlocalhostalienreports*******.bak' is incorrectly formed. SQL Server cannot process this media family. VERIFY DATABASE is terminating abnormally.
This happened both when using the .bak file from my old host and after restoring that file on my local machine using SQL Server Management Studio 2008 just fine before backing it up and getting the same error when trying to upload and restore.
I'm trying to create a database within the app_data folder of an asp.net mvc project using the IDE, but i am getting a "Required Components Missing" message indicating "Connections to SQL Server files (*.mdf) requireSQL Express 2005 ....."
I am using
- Windows 7 Enterprise
- VS2008 Team System SP1
- SQL Server 2008 Developer Edition SP1
I have altered the database connection to use the default instance by setting to blank using
Tools -> Options -> Database Tools -> Data Connection : SQL Server Instance Name
I also note from the SQL Server Books Online that the user instance feature will be removed in the future, but for now it suits my effort in developing an application where a number of people are working on the project.
Has anyone managed to create a database in the same manner?
I have a masterpage setup, with a pageLoad in the topmost masterpage, which calls pageLoad2 for nested masterpages which calls pageLoad3 for content pages.
In my content page I have a jquery click event and in my nested masterpage I have a web user control.
Whenever I use the user control in the nested masterpage, it rebinds the click event in the content page (undoubtedly because the pageLoad3 is called again), but this makes the click event fire twice on a single click. The problem gets worse the higher up masterpages you go (eg. fires 3 times if user control from topmost masterpage is called).
how to make sure it only binds the jquery events once?
I have created roles and users using ASP.NET configurations for login validations, it works fine if I run my application within project but when I publish my site and try to run from my Inetpub it giving this error. I tried all shorts of solutions posted in website but nothing worked for me.

I am new to asp.net. i am just trying to get database query result and store it into label Text in c#. Is there any way to do that?
View 5 RepliesI've created a table with a userId column of type uniqueidentifier, and have set that column as the primary key. In the column properties, under the Default Value or Binding, I've put (newid()). I thought that this would create a new uniqueidentifier if no value is specified in the insert statement.
However, when I try to add a new row in the table data view and leave the userId blank, it does not let me add the row. It gives me an error saying that the value cannot be NULL (since it is a primary key), however I had deliberately left it NULL so that it would add a new value by calling newid(). Have I made a false assumption?
I have an ODS control populating a Telerik grid. The ODS definition is pretty simple. It's set to call a method on a static class that has one parameter (entityID). I set this parameter in the OnSelecting event. When I test this, the world is a happy place and all is fine.
Then, I pass a query string to the page (which sets various unrelated values for the page, we'll say parameters X and Y). The page call's Telerik's radgrid.Rebind() event. When this happens, an error is throw from the ODS saying that the underlying method (the static data procedure) does not support parameters X and Y.
So, why is ODS thinking it should be using any querystring values at all when I have explicitly set the entityID parameter (of type Asp:Parameter)? How do I stop this from happening?

The OnSelecting:

I see this odsList_OnSelecting being hit and the inspection of e.InputParameters only contains my expected single entry.

VS2010/C#. I have a gridview bound to a SQL Server table with the default SELECT statement returning only a few rows. This is straight out of the box, so no need to show markup.
Upon a button click event I update the datasource: SqlDataSource1.SelectCommand = hdnSQL.Value; Then bind: qlDataSource1.DataBind();
But when I run this, I get this error:
System.Data.SqlClient.SqlException was unhandled by user code. Message=Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
I am clueless. I have done this many times in the past and NEVER encountered a timeout.
