VS 2005 Dataset Xml Load?

Mar 15, 2010

I have the following function: Public Shared Function GetLookupTableData(ByVal TableName As String, ByVal WhereClause As String) As DataTable

[Code]...

With one xml file it loads the schema and data just fine, but with another xml file it only loads the schema and not the data. There's no error thrown - just no data loaded.

Anybody have any ideas? I've attached the .xml file for your review. I would have attached the .xsd but the system wouldn't allow it.

Forms :: Progress Bar And Load Dataset?

Dec 17, 2009

so what I want to do should be pretty simple. I've been following the examples found here Using the BackgroundWorker Component - VBForums . I've been successful, but I'm not smart enough to put it in my project.

What I'd like to happen is this

1. I hit a button to load data from a dataset....

2. have a progress bar show until this action is complete.

The main problem is that I can't figure out how to tie the "progress bar" to the action of "pulling the dataset"

I'm sure this is a crazy question for you all, but hey...

Would I put all of the coding in the button_Click sub?

Load Xml String Into Dataset/datatable?

Mar 27, 2009

I have returned xml data in a variable and need to loop through the returned xml and pull certain data from select nodes.

I was thinking the best way would be to load into a dataset (or datatable) and loop through that.

I also have the xmlschema. What's the best way to code this?

I thought I could do something like so but it gives me the following error: DataTable 'newdt' does not match to any DataTable in source.

SQLDataAdapter Fill Dataset/Load Gridview/Update?

Mar 9, 2011

I'm still in my novice stages of .net development, and I think I may be trying to make something too complicated.In VB.Net 2008, I'm using a SQLDataAdapter to Fill a dataset with records being returned from a Stored Procedure (SQL Server 2005).I'm using that dataset as the datasource for a gridview. Up to this point, everything is great and I understand what's happening.I'm getting ready to make my first-ever attempt at updating the data in thegridview and then pushing the updates back to the SQL dB.Here's where I'mgettingconfused...to cut to the chase, what's the simplest way to load the updates back into SQLServer?

.net - Going From Excel To A DataSet Or DataGridView

Jul 28, 2010

I have data that I'm taking from an Excel sheet with the ultimate goal of displaying in a DataGridView.

Currently I am just going over the UsedRange of excel data and plugging it into a datagridview. This works fine, but can get bogged down when there 100+ rows of data.

I have also toyed with going from excel into a dataset (using the same wasteful method), and as expected it takes about the same time to load the data. Maybe use the XML from the Excel file?

EDIT:

Some Additional Information:

This is a WinForms application and the user will be picking and loading the excel file at run-time.

EDIT

The Return of Some Additional Information:

The Excel file is located on the user's pc. The general assumption is that they will be loading different files each time they use the application. [not sure if this helps, but might be good to know :)]

Datagridview That Is Bound To A Dataset?

Apr 9, 2012

Okay so I have a datagridview that is bound to a dataset. I have a column called type is a string char of either C, R, A, or V. The problem is that I want to sort the datagridview rows using that column and do so in the order I just gave so I want rows with C on top and then R and then A and then V. Because these aren't alphabetical, how could I sort the items this way? I did look into the icomparer, but really wasn't able to figure out how that works.

Datagridview With Dataset As Datasource?

Jan 13, 2012

my question is, is there a way to filter records in the dataset and use that records to fill in the datagridview? for example, a datatable (with 3 columns: ID, StudentName, Gender) is filled with list of students. i have two datagrids in the form namely DatagridView1 and Datagridview2. DatagridView1 is where the the list of student where Gender is equal to M and DatagridView2 is where the the list of student where Gender is equal to F.in my current solution, i am using a loop.

[code]...

is there a way without using a loop?

Dataset And Datagridview Not Synchronized?

Apr 22, 2010

I have a data bound datagridview where I am allowed to add and delete rows.So a new row is the last row in the grid with the '*'. When a user starts to type in the new row, that row no longer is considered the new row. It is then inserted into a row above the new row (*). The user, however, can press 'Esc' key and this row gets deleted.If the user does not pressed 'Esc' but move the cursor along that row, this row will be permanently there. I have tested this scenario and check the underlying dataset and it registers no changes as in the myDataset.hasChanges=FALSE.If I call myDataAdapter.Update(myDataSet), nothing gets updated. How do I save this row to the database?

IndexOutOfRange From Datagridview When Refreshing Dataset?

Oct 6, 2010

I have a datagridview on a form that is bound to a table in a dataset from another class.I use a data adapter to .Fill a table in that dataset and the grid displays the data fine.Works fine.On my form I have a textbox the user can type in that will will pass a parameter to the storedprocedure used to fill this table. So on startup the textbox will have "%" in it. and then the user can type in "F%" and get everything that starts with an "F"

So when that textbox changes I launch an async refresh (.BeginInvoke) to do my refresh. The table gets populated with the reduced number of records (I check ds.table(0).rows.count and it is correct)

But the datagridview then starts throwing datagridview.dataerror events. "System.IndexOutofRangeException : Index # does not have a value".It looks like the dataset is getting filled correctly and not having any issues, but the datagrid is not liking this update. The index out of range error is so common that I'm not finding what I need through searches.

DataGridView - Create New Row And Update DataSet?

Jun 10, 2009

I have a datagridview that was bound using the wizard and all the column created that way. So I haven't done any code to bind the datagridview. It will pull the data from the database and dataset just fine. My problem is when I create a new row it won't update the dataset or database. I have tried different ways that I thought it would work in the code and still haven't found a usable way to do it yet. Or if I need to do all my binding and columns through code give me an idea where to start if I have to go that route. This is my first experiences with Datagridview. I normally use comboboxes and textboxes to write to a dataset and database which all work very well.

Basically, This is a projects form and the user needs to select the the primary contact which is contrained by the customer id (GETbyCustomerID) set in another field. I have it working... mostly except the combobox only displays the contact ID which is completely useless to the user. I need to know how to display the First and Last name (both are seperate columns in the table).

DataGridView Does Not Refresh After Dataset Update?

Apr 13, 2012

I have a vb.net form with a dataGridView

The dataGridView data source is the dgvTableAdapter with this sql statement

SELECT membres.ID, membres.refere_par, bands.titre,
membres_1.prenom & ' ' & membres_1.nom AS reference_nom
FROM ((bands INNER JOIN membres ON bands.ID = membres.[band])
INNER JOIN membres membres_1 ON membres.refere_par = membres_1.ID)

[Code]....

I know the delete statement works because I saw the changes in the database. If I close the form and reopen it, the dataGridView is up to date.

The membres table is an access table

I'm running the app in visual 2010 debug mode.
