to get limited records using this method? i.e. by filling dataset using adapter and providing min and max record limit?I wish to do custom pagination using this method.
I am trying to update an access DB using a table adapter created within a vs 2010 dataset file. When i click my submit button nothing happens. Also using an insert method created the same way it works.... When I dubug using the immediate window i receive this message:
Argument not specified for parameter 'StockNum' of 'Public Overridable Function UpdateQuery(StockNum As String, Year As String, Make As String, Model As String, Color As String, Location As String, TiresNeeded As Boolean, StockIn As Date?, SvcRONum As String, UCIStartDate As Date?, UCIEstCompleteDate As Date?, Repairs As Boolean, CollisionRONum As String, Detail As Date?, Other As String, OnLot As Boolean, OffProperty As Boolean, Sold As Boolean, Original_RecNum As Integer) As Integer'
The PK column in this DB is recNum. Here is a snippet of the code:
Code: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load getData(Request.QueryString("param1")) End Sub Private Sub getData(ByVal user As String) 'declare variables to fill
I have a strange issue. I have a XSD file where I have created some TableAdapters. When I have reopened the XSD file it seems like I am not able to create a new table adapter since all the options which will come when I right click on the XSD file are disabled. I have cross verified whether I am on debugging mode but...I was not..(I am not even able to drag and drop an adapter from the left toolbox menu either)I am getting the same issue when I open the same XSD file on somebody else machine but I am able to create TableAdaperts in other XSDs.Can somebody suggest me a solution for this
I have a profile of member to be displayed. I am using a dataset with all the data table adapter to retrieve the information from database.
I have a memContact method which has NRIC and Number as a composition primary key. Thus, automatically, the table adapter has created a method called FindByICNum () for me. However, when I do the search to display the contents, i will only need to search by memberic instead.
Is there anyway to change the table adapter query?
I'm creating an quiz application which queries the database and extracts the questions and choices. I use dynamically created controls such as a checkbox list and fill the values dynamically. How do I do this? Right now I have these functions:
array_random_init(); this creates a 10 element integer array from 1-20 - extract_question(i): this extracts a question indexed at i in DB, I created the controls and set the appropriate text in this function. - validate_question(i); this is called by button_click and validates the question i according to DB.
I understand I have to recreate the controls in Page_init on postback, but what should it look like? Do I need to add "if IsPostBack" in page_init, or do I create the controls in page_init() and reset their properties in page_load when I use extract_question(i)? Also, I cannot seem to clear the selected boxes on postback, I added page directive "enableviewstate=false" but it doesn't work.
I am using table adapter in a dataset type (.xsd) file mapping to database. But I found after I created a new stored procedure in database and use table adapter mapping to the new stored procedure, I got method not found error like
Method not found: 'PO_GetNewOrdersSummaryDataTable BizTalk.Application.DataAccess.DatalayerTableAdapters.PO_GetNewOrdersSummaryTableAdapter.GetDataByCompletedDays(System.String, System.String, System.Nullable`1<Boolean>, System.Nullable`1<Boolean>, System.Nullable`1<Int32>)'.
on the testing server. But it is fine if I run the web application on my local dev machine and another machine we use it for building application before deployment. Does anyone know what could cause this problem on testing server? It works fine before I created the new method
GetDataByCompletedDays in PO_GetNewOrdersSummaryTableAdapter.
I've been attempting to walk through the "Creating a Data Access Layer" tutorial found [URL]I create the DB connection, create the typed dataset and table adapter, specify the sql, etc.When I add the code to the presentation layer (in this case a page called AllProducts.aspx) I am unable to find the NorthwindTableAdapters.ProductsTableAdapter class. I tried to import the NorthwindTableAdapters namespace, but it is not showing up. Looking in the solution explorer Class View confirms that there is a Northwind class, but not the namespace I'm looking for.
I've tried several online tutorials that all have essentially the same steps, and I'm getting the same results.Can anyone give me a push in the right direction?I'm getting error: Namespace or type specified in the Imports 'NorthwindTableAdapters' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member.I think I might need to add a reference OR they may be creating a separate class and importing it into their main project. If that's the case, the tutorials do not mention this.

Using VisualWebDeveloper 2010 on the development machine. All nice and fast.Using VisualWebDeveloper 2008 on the server. Server runs on Windows Server 2008 and has IIS 7.
It looks like that when 'table', a datatabe filled up in C# code behind, is getting longer, then the server (whether running the website on IIS or on the local host of VIsualWebDeveloper2008) is really slowing down. Checked it in debug mode and traced it down to
Adapter.Update(table);
Are there any know issues? Could it be that there is incompatibility between different version of SQL server or something like that? The update works, it is just awefully slow, but only on the server.
1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
When I want to get the output values its okay but I also want returning a table as a result data.But Datareader has no rows.is it possible if I want a returning query result and multiple output values togather ?I wrote a test above.I can get output values as sqlparameters. But Datareader attached to a Gridview is empty.can you detect whats wrong here and it doesnt return a query result.So stored procedure is not standart or ı am doing something wrong.this doesnt raise any exception.but not returning any data.
I was having issues with a gridview and CSS so I posted my question here and received a wonderful answer which lead me to implementing CSS Friendly Adapters for all of my gridviews.I have a table nested in the EditItemTemplate that holds the textbox and the button for a calendar control where I want them, it inherits the CSS applied from the CSS Friendly Adapters. I don't want it to change the CSS so I have changed the CSS inline, with no success. More importantly...
I also have a Ajax calendarExtender control to change the date for that field. When the popup is displayed the table in which the calendar is shown in also inherits the CSS Friendly Adapters code. I have tried fixing this by creating a external css sheet for the calendarExtender's cssClass property and a blending of CSS occurs where the items not specified by the Friendly Adapter Code are set correctly by the calendar.css file that I created.Is there anything that I can do to force the tables inside of the gridview to ignore the inherited Friendly Adapter Code?
Just want to know if it is possible to Dynamically Populating a DetailsView with OleDb Data Adapter ? It has to be done on the Page_load because it has to display a users details that i must be able to edit!
here is my code for selectiong some records from db table
string strSql = "select * from mtblNBD where SentTo=@SentTo and InternalStatus Is NULL order by DeadLine desc"; SqlCommand com = new SqlCommand(strSql, con); com.Parameters.Add("@SentTo", SqlDbType.NVarChar, 50).Value = (string)Session["uname"];
here I am using parameters for SenTo field but not for NULL so it is ok... or should I use parameters for this field where value is NULL , if yes then how can I use parameter for this
I am trying to run a linq query but I need the result as a datatable as I am using that to store records from different queries in the same viewstate object.The 2 versions below compile, but return an empty set. The exact error is "Value cannot be null.Parameter name: source". (and yes I have checked there is data):
MyDatabaseDataContext db = new MyDatabaseDataContext(conn); IEnumerable<DataRow> queryProjects = (from DataRow p in db.STREAM_PROJECTs.AsEnumerable()
I want to create a mailto anchor tag at runtime. Is this possible? I've tried this:
[Code]....
Neither of these worked. I tried adding the "mailto:" in front of the {0}, but this just became part of the perceived URL. I read a post online about using data attributes to add the value as a property of a class, but I can't do that, as I'm stuck using .NET 3.5 for this project. I honestly didn't think this was going to be such a big deal. I just want to populate the email address of the anchor tag with a variable value.
'm not sure if this is the right forum, but I couldnt find one for linq related questions.I have the following problem. I have four tables, One with users, one with projects, one with the users and the projects they are in (joinProjectTable) and on table where the users can fill in there worked hours for a certain project. These hours are filled in on a daily base. Now every month there is going to be created a report on the workedHours table so there is visible which user has entered how many hours for a certain project. On this report there is gonna be a billing for the company where for the hours are worked. This is the easy part, the hard part is the following.
companies also want to have a list of users that didn't entered any hours for that particular month for a particular project. So I have to write a linq query that would look in the joinprojecttable to see which users are joined to which projects, and than with that join it should look if that particular combination (user+project) is in anyway entered in the workedhourstable for that particular month. If not this has to be shown in the datagrid, for every user that isnt in the workedhourstable for that month. So it should be a certain NOT query, but I can't seem to figure it out.does anyone have any idea to accomplisch this in Linq2Sql? I'm using VB instead of C#.
I want to fill the combobox by using the table value.
OdbcConnection con = new OdbcConnection(); OdbcCommand cmd; con.ConnectionString = ""; con.Open(); cmd = new OdbcCommand("Select no from table", con); ada = new OdbcDataAdapter(cmd); ds = new DataSet(); ada.Fill(ds); combobox1.Items.Add(ds);
But no values was loading in the combobox, what wrong with my above mentioned code.
I'm new with programming. I have a GridView that have the specific user data. When the user log in I retrieve the data for that specific user. All I need is; How do I make the gridview get the data of the logged user using a datatable that has a query. Just bind it with the datatable.This is some code that other programmer made, I continue his work.
I have 40 Drop Down Lists that I want to fill using an XML file. Based on what is in the XML file i will add an item to a specific Drop down list. I don't want to manually loop thorugh each control by name. the ids for all of the controls start with DDLSession and then they have a suffix such as A2 or B4. What I want to do in the C# Code is ads items dynamically to the control like this:
