View 12 RepliesI'm working in VS 2008, vb.net. I have a data grid that is getting filled based on a store procedure. When I preview the datagrid, I will get 29 rows back. This includes rows that have NULL values in it. And that's what I need. But when I run the program, it will only return in the Datagrid 12 rows, the rows that don'r have any NULL values. Where or how can I change it so the DataGrid will show NULL values?

View 5 RepliesI'm currently attempting to save data inputed into a data grid clicking the "save" button. My problem is, I also have another DB opened in the same window that also needs to be saved.

I try to run the update command it always throws the exception "Cannot find table 0" or "Update unable to find TableMapping['Table'] or DataTable 'Table'." I tried declaring the connection the same way as the code above and then simply calling the da.update(ds) but it wouldn't do anything.
After I have retrieved my data from my access database, I would like to insert text into one of the columns in a new row. Is this possible? Here's a snipit of my code I use to retrieve the data from access:
If con.State = ConnectionState.Closed Then con.Open()
sdr = cmd.ExecuteReader()
rtime = Now()
[Code]....
It's the rtotal_time value that I need to insert into a new row, in and cell, the datagrid.

View 1 Repliesi have an owner drawn list box which is connected to a SQL database source. When the list box is owner drawn, my list box is filled with the text "System.Data.DataRowView". When i turn off owner drawn it works perfectly.
The problem is, i need it to be owner drawn as it is a crucial part of my program. Is there a way of keeping my owner drawn list box and preview the data from the SQL database at the same time? Here is my code for the owner drawn part, most of this is irrelevant, just mainly look at the bottom bit where i print the string, with the variable 's' and 'drawstring':[code...]

Friends I have Developed my Data base Project on vb6, using adodc and datagrid using ms access database file, it was working nice in vb6, I also put Search box there and used adodc1.recordsource="select * from table" sql query.
later i needed to convert it in vb.net I converted it, every thing is working fine, but one problem appears, an adodc's Recordsource query for searching records is not working, it only works if there is data in dataset (Datagrid),suppose once i pressed search button to search record and if no record found then dataset / datagrid becomes empty, now i wanted to search an other record with other name, but this time it does not work and following error appears Either BOF or EOF is True, or the current record has been deleted. Requested operation requires a current record.

View 2 RepliesI am creating an app to grab data from excel and preview in datagrid. From the datagrid I want to be able to save to a sql table. I have the excel data in a gridview via a dataset. What I am having trouble with is the sql statement. I know how to insert data, but I can't work out how seperate the data in the dataset to pass it into individual Values of the insert statement. Or should it be done another way? NOTE: I is not essential that the excel data be previewed in the gridview if this would make life easier for me.

On the left half of my screen I have a datagridview. On the right half I have a document preview pane.As I change rows on the left half, I use the CurrentCellChanged event to open the document associated to that row in the previewer.This works fine, however, the focus is then placed in the preview pane which prevents the user from being able to use the arrow keys to step down a row at a time.To combat this, I made the final event in my CurrentCellChanged routine set the focus back to my datagridview. Unfortunately, even this doesn't always work because of what seems to be a timing issue.If the document to be previewed takes more than a fraction of a second to open, the code to move the focus to the datagridview is executed but after the image completes drawing, the focus is moved back to my previewer.I don't want to use a timer to force a delay and a DoEvents causes me some other issues.Is there some other event I can use to determine when my preview pane is complete and then and only then set the focus back to my datagrid?
