Configuration :: Adapter.Update (table) Fast On Development Machine, But Very Slow On Server?
Oct 17, 2010Using 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.

C# - Datatable.compute Slow With Like Condition?
Jan 12, 2010I have a problem with my asp.net program. I am doing a Datatable.compute on a very large database with a like condition in it. The result takes something like 4 minutes to show or does a Request timeout. If I do the same request with a = and a fix text, it takes nearly 1 minute to show, which for my use is acceptable.
Here is the line that is so slow:
float test = (int)Datatbl.Tables["test"].Compute("COUNT(pn)", "pn like '9800%' and mois=" + i + " and annee=" + j);

ADO.NET :: Getting Full Recordcount From Data Adapter?
Jan 27, 2011I'm new to .net... long time programmer though
I'm trying to return the full recordcount of a data adapter but I'm struggling.
This is a snippet of the code I am using
[Code]....
This works ok but it only returns the number of records I am actually filling into the dataset table.... So my query might return 700 records but because I am only returning 15 back into the dataset table (to paginate the results) then it only shows 15 records found.
Do I have to fill a 2nd dataset table with the full results set and count that? Should I return a count of records as a column in the products table.
What's the correct way of doing this (and what's the most efficient way of doing this)?
VS 2010 - Ineffective Table Adapter

DataSource Controls :: Not Able To Create A New Table Adapter?
Jan 11, 2010I 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
View 5 RepliesUsing Business Object Dataset Adapter; Works On PC Not On Server?
Jun 26, 2010I am a new to ASP. Very experienced in MS Access... Logical move to ASP.
Problem:
When designing my first .aspx on PC and testing via localhost; all is well.
When move to server I get this error msg:
"The type specified in the TypeName property of ObjectDataSource 'ObjectDataSource2222' could not be found."
I have been reading for a solution for the past three days.
My reading tells me that there should be a reference somewhere in the web config file to id the business object dataset , but do not see any. No luck in surfing for a tip either.
I thought Visual Studio 2010 was a rapid app that allow one to design and test on PC and move easily to server for production. I am I expecting to much.

View 6 RepliesFinding CSS-Friendly Menu Adapter That Emits The Same Markup As 4.0?
May 12, 2010For .NET 2.x/3.x there exists a CSS-Friendly Adapter on CodePlex that emits markup for an ASP.NET Menu Control as an ul.
The .NET 4.0 Menu control will also emit an ul, but the CSS class names are different from those emitted by the CSS-Friendly Adapter 1.0 on CodePlex.
In the interests of having a single version of CSS for .NET 2/3/4 sites, I want to create a version of the CSS-Friendly menu adapter that emits the same markup as the .NET 4.0 Menu control.
DataSource Controls :: Adapter.Update Is Not A Member Of TableAdapter
Mar 4, 2010I have created a function that is called when a user wishes to upload a file to the database. The problem I am having is that it won't write the files to the database anymore. This function used to work before I implemented a treeview (which connects to the database). I am struggling to see how the treeview could have cause the file upload to stop working (the error may not even be related to the implementation of the treeview).
The error message I am receiving is: 'Update' is not a member of 'CMS.SiteFilesDSTableAdapters.SiteFilesTableAdapter'.
The code for the upload function is:
<System.ComponentModel.DataObjectMethodAttribute(System.ComponentModel.DataObjectMethodType.Insert, True)> _
Public Function AddSiteFile(ByVal FileData As Byte(), ByVal FileName As String, ByVal FileDescription As
[code]....
It is throwing the error at: Dim rowsAffected As Integer = Adapter.Update(SiteFiles)
' Return true if precisely one row was inserted, otherwise false
Return rowsAffected = 1
EDIT: I managed to solve this problem by following:
http://www.asp.net/%28S%28pdfrohu0ajmwt445fanvj2r3%29%29/learn/data-access/tutorial-69-cs.aspx
Basically, I had used an Inner Join to gather all the fields, and table adapters don't seem to like them.
INSERT INTO [SiteFiles] ([FileData], [FileName], [FileDescription], [FileType], [FileCreated], [FileCreatedBy]) VALUES (@FileData, @FileName, @FileDescription, @FileType, @FileCreated, @FileCreatedBy)
ADO.NET :: Data Adapter Update Method With Command Builder
Nov 11, 2010Code:
SqlDataAdapter da = new SqlDataAdapter("select * from " + txtTableName.Text, DataStoreGeneral.GetConnectionString());
DataTable dt_app = new DataTable();
da.MissingSchemaAction = MissingSchemaAction.AddWithKey;
da.FillSchema(dt_app, SchemaType.Source);
da.Fill(dt_app);
SqlCommandBuilder build = new SqlCommandBuilder(da);
da.InsertCommand= build.GetUpdateCommand();
da.Update(ds.Tables[1].GetChanges(DataRowState.Added));
Problem: In my scenerio i had dataset with a table (in code->ds.Tables[1]) in rowstate added. I wanted update on database with this table so i changed insert command of adapter to update command of command builder, but no update got performed. When debugged in sql profiler i found that update command generated by builder is checking all columns in where clause and with parameter value of data table instead of from database column value.
exec sp_executesql N'UPDATE [ShopResources] SET [GROUP_RESOURCE_ID] = @p1, [SEQ_NO] = @p2, [SUB_RESOURCE_ID] = @p3, [EFFICIENCY_FACTOR] = @p4, [RUN_COST_PER_HR] = @p5, [RUN_COST_PER_UNIT] = @p6, [BUR_PER_HR_SETUP] = @p7, [BUR_PER_HR_RUN] = @p8, [BUR_PERCENT_SETUP]
= @p9, [BUR_PERCENT_RUN] = @p10, [BUR_PER_OPERATION] = @p11 WHERE (([GROUP_RESOURCE_ID] = @p12) AND ([SEQ_NO] = @p13) AND ([SUB_RESOURCE_ID] = @p14) AND ((@p15 = 1 AND [EFFICIENCY_FACTOR] IS NULL) OR ([EFFICIENCY_FACTOR] = @p16)) AND ([RUN_COST_PER_HR] = @p17)
AND ([RUN_COST_PER_UNIT] = @p18) AND ([BUR_PER_HR_SETUP] = @p19)
The problem I identified is parameter values inside where clause are from data table which is obvious that update condition will not be met. Is there some way to restrict where clause to primary key only in Command Builder?Or why is command builder taking where clause parameter values from datatable instead of command (query)?

ADO.NET :: Using Table Adapter In Visual Studio To Retrieve Data?
Nov 19, 2010I 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?
ADO.NET :: Dynamically Fill Query Parameters In A Table Adapter?
Sep 18, 2010SO I have created an object data source on a page from a table adapter using the various Wizards in Visual Studio.
Its meant to query a diary Database by a DateTime parameter called diaryDate. I want to query from a date Now to the next 14 days ahead.
I want to display the entries in a Grid View when the page loads.
So I'm a bit stuck now as to how to set the two query parameters date1 and date2. I want to set date1 = now() and date2 = now() + 14 days.
How do I set those parameters when the page loads ?
Should I have used the adapter Wizard approach of do I have to write all the code in the code behind page ??

Configuration :: Method Not Found For New Table Adapter Using Stored Procedure
Aug 31, 2010I 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

Default Control Adapter Mappings Work On Chrome Or Safari?
May 22, 2010I have confirmed that my Control Adapters are not triggering in Chrome and Safari. I've debugged, and the breakpoints inside the adapters just don't get hit in Chrome/Safari, when they work perfectly find in Firefox/IE. So, for Chrome/Safari, IIS is just ignoring the mapping.
My AdapterMappings.browser file looks like this:
<browsers>
<browser refID="Default">
<controlAdapters>
[...adapters here....]
</controlAdapters>
</browser>
</browsers>
This should provide mappings for all browsers, correct?
I used the Charles proxy to check what user agents were being sent. They are:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1064 Safari/532.5
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/531.22.7 (KHTML, like Gecko) Version/4.0.5 Safari/531.22.7
Any idea why this would be? Everything I've read tells me that my browser mappings are correct? And, as I said this works for IE/Firefox, so I know my configuration is technically correct.
