i know the record position or number of datatable and the same table is used as datasoure to grid. i want to find out the row number in the grid for current record in datatable. in case grid is not sorted it is easy but if grid is sorted then row number change in the grid.
View 3 RepliesI'm working on a VB Winform project using Visual Studio 2008. The form's controls are all bound to a bindng source and a binding navigator which are tied to a dataset class. When the form is displayed, the first record is displayed as well. However, one of the controls (Radio button) is not showing the correct data from the data set. However, if I navigate to the next record and move back to the first, the radio button properly displays the correct information, so it appears the binding source is working the way it is suppose to.

View 1 RepliesTake text data from a small file and display it in a form using a DataGrid.
I am trying to make the program so it will allow the user to choose which file to open (this part already works). I have stepped through the code and found that the rows are being added to the table, but when the action runs to completion my form has no data on it. Here is my code (forgive any code shortcomings as I have exactly three days as a VB.NET programmer).

I have a datagridview with transaction bindingsource I want the datagrid to show the sorted rows only not all the records when i enter a value into a textbox and click button sort.
View 1 RepliesVisual Studio Pro 2010 Win 7 64 bit running bootstrapped to a MacBook Pro i5 (blasphemer!!!) works really well though!!New to vb.net, have used vb6 for several years and finding the transition interesting to say the least.I have an access database with a vb.net front end all auto bound by the connection and binding wizards (I know, I know...) Not too complicated, but a simple 2 table related db. On the form the parent table shows customer details with the child table related and displayed by datagrid. I have a field in the child table for images and I have figured out how to store and retrieve images to the db. I am using the datagrid.rowheadermouseclick event to reload the picturebox on the main form as I click down the child table datagrid. Now I need to be able to click the bindingnavigator, go to the next record and have the program reload the image for the next child record. The problem is I'm trying to use an event from either the datagrid or bindingnavigator to reload the picturebox in the child table after moving to the next record, but all of the events I am trying are firing before the next record is moved to and therefor the logic I'm using to retrieve the image from the db is not working.
Anyone with an idea on how to move to the next record and then run my logic to populate the picturebox? What events might I use that fire after the next record has been populated? I know this is probably not that hard, but I have been racking my brain all day now.
I am handling many of the BindingNavigator tasks (MoveFirst, MoveNext, etc.)in code to ensure that I always ask the User to save his changes.
The one area I am have a problem is PositionItem. I would like to sense that the User has changed the Record Number in the BindingNavigatorPositionItem, handle my record Update, and move to the Record Number the User entered I have looked all over and have not found any way to do this.
I refreshed my data sources to include additional items from the SQL Server databases and it appears that my entire data source from my VB.NET project disappeared.I am using Entity Framework. I may have clicked on something wrong, not quite sure. Unfortunately I can't recreate the Data Source without creating a new Entity and Data Model.I can delete the entry in the App.Config file and recreated it, however things aren't quite right.Is there a way that I can recreate my Data Source from the entry that is in my App.Config file...since that appears to have remained intact.BTW, I can go to my Data Model and successfully refresh from there, however my project isn't connecting to the database so I have quite a number of errors until I can get reconnected.

View 4 RepliesI'm testing a small program that can read & write to an rtf file. Examples I have found work fine, although I have two questions:
1)If I need to ALWAYS write to line number 9 of an existing RTF file, do I need to "read" 9 times or can I immediately position myself to line number 9. I have found character manipulation but can't seem to find what I need with positioning to a particular line number.
2)BOLD text: I have found examples where I should be able to format my text, such as
MyFile.WriteLine ""
MyFile.WriteLine Text
MyFile.WriteLine "0"
but when doing this, it does not "bold" my text, but actually prints the text exactly as shown. I'm looking for information/links that I can "bold" "Italicize" text. Code is written in VS2005.

I have a form with a datagrid, few buttons, and textboxes. I can add the new record in data table and can display in datagrid. The problem is that... the new record which i have inserted in data table is been displayed at the last row of datagrid which i am having trouble finding it out whether the data is been inserted or not.
1. my question is how to display new record / row inserted in datagrid at the first, so that i can see the data is been added.
2. how to display numbers of record which i have seleted in data grid e.g. 1 of 20 when i select first row and 2 of 20 when i select second row. i can display only total number of records of datagrid.
