Web Forms :: Maintaining Global Settings For All Web Parts?
Jan 18, 2010
My web parts need to get data from a remote server using TCP/IP. I want to store these application specific settings and allow only an administrator to configure it. Where should these settings be best stored ? I guess these settings could be stored in web.config. I want to avoid manually editing it or build a separate administration application. Could only an administrator only web part edit those settings which could be then available to all the web parts to use ?
I'm working on a new C# web application in Visual Studio 2010, and am having problems reading a value in Web.Debug.Config from the GLobal.asax.cs file.
In the Application_Start event I've got the following code:
When running in debugger, I've got a break-point in the Application_Start event in Global.asax.cs. It hits the break point, but in all cases the value coming back from ConfigurationManager is coming back null. What am I doing wrong?
I have some global settings in my application that is going to be handled by the administrator and I store them in the database.
Settings like: board on/off, max items/page on different UserControls, language, hide/show modules.
What technique should I follow to read the values in the database and display the page or the application according to it .. Of course I could do it the easy way and fetch the required settings for each page in the Page_Load event handler but I think that will be a lot of database connection!
My web application has hosted on the canada server but my all clients are indians.So, as I am using System.datetime.Now to store all the dates in application.Obviously, it is displaying the canadian time instead of india time.How can i do it?Is there not any gloabl settings that we can do in our web.config file so that it indicates to the server at run time which time zone to execute..?Or any other suitable alternate?
We have many different clients, and each client can have multiple user accounts.Right now, we have user settings set up on the ASP project, and a WinForms application can see these settings, depending on which user logs into the winforms application. They are specific to the user. I want to make them specific to the client, so users can be in "groups" by their client, and all users in the group would see/update the same settings.
I know there is a couple answered questions on here regarding "request scoped" globals, but I want to nit-pick on something specifically and maybe squeeze some extra enlightenment out of one or two of you.I have an ASP.NET C# Website and a static Dictionary of objects (loaded from DB once on Application start). Each page request will need to do a lookup in the Dictionary (based on a key derived from the request url/etc) and get the appropriate object.The issue is I'm trying to maximize efficiency by reducing the lookups to the Dictionary per Request. Doing just a single lookup within a Page itself is easy enough and I can pass the object to sub controls, etc too.. but global.asax is separate from the Page and it also needs to use the object (in Application_BeginRequest and Session_Start).
So is doing a Dictionary lookup once in Application_BeginRequest, once (when necessary) in Session_Start and once in the Page negligible speed wise, even if there are many requests coming in every second?I would like it if I could just have a Request scoped global variable that I can easily call upon.. the only one I see available though is HttpContext.Current.Items and that is a Dictionary itself.Am I beingridiculously nit-picky with my concern over efficiency? or will these milliseconds (nanoseconds?) get me in the long run when more and more requests are being made?
PS. I currently only have around 100 objects in the Dictionary although this may increase in the future.
Our application is on NLB. Now we have functionality where administrator can upload the images, files that user can see. We have two serversserver1 and server2. We are having only one databaseIf user hits the website and NLB directs it to server1 then the uploaded images will get uploaded in server1 only. with the result if user hits the application and it will get redirect to Server2 he will see the data but no image.Platform :ASP.netWindows 2003 server
I notice that my generic list is maintaining only one item, i declared it in the aspx.cs page f one of my forms. I am assuming that each time the page is reloaded when I add an item the list is redeclared. How can I stop that?
i have a problem with maintaining a scroll after postback in grid which consists of number of records with vertical scroll bar,when i click on edit link the scroll is moving to top row but not the current updated record i have used MaintainScrollPositionOnPostback="true" and i placed my grid within div tag but it is not working for my grid
while using gridview whenever I go to edit an item it increases the row size - but this is because I have a multiline textbox as one of the edititemtemplates. It also increases the size of every row to the same size as the one that is being edited. Is there any way to keep the rest of the rows the same initial height and have an increased size just for the row being edited?
have some code which dynamically generates a number of drop down lists to provide the user with different options. The items in these drop downlists contain a value which is a unique id for that particular combination of options and a text component which just plain text but not neccessarily unique. I then have assigned a handler to these dropdownlists which is called on selected index changed to perform the relevant actions based on what options are selected. The problem is to make the system perform the correct action I need the unique ID from selectedValue of the drop down box but when it posts back it appears the selectedValue has been replaced to match the text of the item.
Dim dynDdl = New DropDownList() dynDdl.ID = "ddlOpts" & i dynDdl.AutoPostBack = True AddHandler dynDdl.SelectedIndexChanged, AddressOf dynDdl_selectedIndexChanged [code]...
I would like to monitor the entire project through the clicks. For example if i open a new page and clicking any control it should get monitored like ( User x clicked this many events on this page )
I have a List box that displays my Vendors, and then I have a Gridview that shows payments made to those vendors. Is there any way of making the gridview always show 12 rows, regardless if 4 payments were made or even 0 payments have been made ?

I have one more datagrid in the same page. I want to apply same Javascript to that datagrid also. Here is the javascript I used.
<script language="javascript" type="text/javascript"> var scrollTop; Sys.WebForms.PageRequestManager.getInstance().add_beginRequest(BeginRequestHandler); Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler); function BeginRequestHandler(sender, args) { var m = document.getElementById('divexample2'); scrollTop=m.scrollTop; } function EndRequestHandler(sender, args) { var m = document.getElementById('divexample2'); m.scrollTop = scrollTop; } </script>
I am working with webpart. I have developed webpart but has some issues in managing its personalization/personal settings.
For example when user A gets logged in and personalize any webpart. Then uer B gets logged so it should have default webpart setting or own personal setting webpart.
I am referring following site:

kindly tell how to use these methods or others which are present in sqlprovider
1) SavePersonalizationBlob
2) LoadPersonalizationBlobs
Is there any tutorials or example to help me or any1 can have idea or example etc to
This is my first time working with web parts. Was wondering if anyone can show me how to create a new webpart project in VS2008. I don't see any options for creating a "web part template" when I go to create a new project.
I am having trouble with ASP.NET and trying to use web parts. I am receiving and error. I am using VS 2008, with ASP.NET 2.0. I create a new project and add the webpart manager and then the webpartzone. I build and run the project and receive the error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
SQLExpress database file auto-creation error:
The connection string specifies a local Sql Server Express instance using a database location within the applications App_Data directory. The provider attempted to automatically create the application services database because the provider determined that the database does not exist. The following configuration requirements are necessary to successfully check for existence of the application services database and automatically create the application services database:
If the applications App_Data directory does not already exist, the web server account must have read and write access to the applications directory. This is necessary because the web server account will automatically create the App_Data directory if it does not already exist. If the applications App_Data directory already exists, the web server account only requires read and write access to the applications App_Data directory. This is necessary because the web server account will attempt to verify that the Sql Server Express database already exists within the applications App_Data directory. Revoking read access on the App_Data directory from the web server account will prevent the provider from correctly determining if the Sql Server Express database already exists. This will cause an error when the provider attempts to create a duplicate of an already existing database. Write access is required because the web server accounts credentials are used when creating the new database. Sql Server Express must be installed on the machine. The process identity for the web server account must have a local user profile. See the readme document for details on how to create a local user profile for both machine and domain accounts.........................
I have a problem with keeping the selected values in DropDownLists in rows in GridView while paging. I have this code behind:
private void RememberOldValues() { ArrayList LinijaIDList = new ArrayList(); int index = -1; foreach (GridViewRow row in GridView1.Rows) { index = (int)GridView1.DataKeys[row.RowIndex].Value; if (Session["equal_ITEMS"] != null) LinijaIDList = (ArrayList)Session["equal_ITEMS"]; if (row.Cells[0].Text == lineTextBox.Text) { if (!LinijaIDList.Contains(index)) LinijaIDList.Add(index); } else LinijaIDList.Remove(index); } if (LinijaIDList != null && LinijaIDList.Count > 0) Session["equal_ITEMS"] = LinijaIDList; } protected void Button1_Click(object sender, EventArgs e) { //Session["equal_ITEMS"] = null; RememberOldValues(); GridView1.AllowPaging = false; BindGrid(); //RePopulateValues(); DataTable dt = new DataTable(); dt.Columns.Add(new DataColumn("LinijaID", typeof(int))); dt.Columns.Add(new DataColumn("Ime", typeof(string))); ArrayList LinijaIDList = (ArrayList)Session["equal_ITEMS"]; //if (LinijaIDList!=null) //{ foreach (int LinijaID in LinijaIDList) { foreach (GridViewRow row in GridView1.Rows) { DropDownList Ime = GridView1.FooterRow.FindControl("ImeDropDownList") as DropDownList; int rowID = (int)GridView1.DataKeys[row.RowIndex].Value; //string Name = row.Cells[1].Text; string Name = Ime.SelectedValue; if (rowID == LinijaID) { DataRow dr = dt.NewRow(); dr["LinijaID"] = LinijaID; dr["Ime"] = Name; dt.Rows.Add(dr); } } } GridView1.AllowPaging = true; Session["equal1"] = dt; Response.Redirect("CheckedRowsPage1.aspx"); } // else //{ // GridView1.AllowPaging = true; // Session["equal1"]=null; // } }
When I insert a value in the TextBox2 and want to select only the rows from the GridView from different pages which have value in the first column the same as the value in the TextBox2, after clicking on Button1 I get this error:
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
I have form and i'm using web parts for asp.net.I want the first web part the stretch the entire width and on the second row I have 2 small web parts to on the second row
<big web part>
<second><third>
But, I can't get the 2nd and third web parts to be on the same line. [Code]....
I am using web parts in my web page( ASP.NET 2.0 and C#).
The contents of these web parts vary in size. For example, one web part has calendar control, another web part has the File Upload control.
I have added the web parts under "td" tag. So the web parts are of different sizes now, I want to make the webparts to be of same height and width, regardless of the content available.
How to set the height and width to be same for all web parts regardless of the content available in the webparts.
Also, when I web page is running, I am able to "WebPartZone1" which is the Id in the page. How to hide that name from appearing.
