Append Text To Data Bound To An Access Database Populated Into A Datagrid?

May 8, 2009

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.

Access To Bound Data Items From A Textbox / When Text Box Is Not On Form

Dec 20, 2010

In my application, I have a data bound form using a binding control (built by the wizard). The application has one primary data screen plus a few more on tabcontrol subscreens.Picture for example that the tabcontrol has two tabs, tab1 and tab2.When the form is displayed, tab1 is visible.Now picture the form or window split in half the top part of the form has a few textbox controls bound to the data and there are a few textbox controls in the lower half of the screen on tab1 of tabcontrol1.There are a few textbox controls on tab2 as well.When the form displays, I can access any of the .text properties of any of the textbox's that I can see on the form and in tab1 of the tabcontrol.BEFORE tab2 is chosen or even, I need to get some of the data from the .text property on a textbox control that is on tab2.I have tried to get the data but as far as VB is concerned, it does not appear to be there UNTIL tab2 is displayed.

To prove this, I put a command button on the form and it simply does this: MSGBOX (mytext box33. text)mytextbox33 is a databound control on tab2 of the tabcontrol1.tab2 is not in focus and apparently, neither is the data.how can I read the .text property of a textbox that is on a form but the form (or tab) is not in focus?

Unable To Save Data From Datagrid To Access Database?

Dec 7, 2009

I'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. The second database is pulled up by the contents of a text box, so there for it has no real Dataset to call on. It looks something like this.

[Code]...

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.

Bound Data Controls - Access ContactID?

Jan 17, 2012

I have a few bound data controls on a form. However, there are certain data fields in the same table from which this data is coming from which I would like to be able to access in memory but which is not bound to a control. I have tried looking through the properties of my datanavigator, my dataadapter and my databindingsource and can't seem to find out how to sort this.

In simple terms, I have a data navigator to iterate through various fields in my dataset. I want to be able to access to the contactID of the currently visible / selected contact. The contact ID exists in the data source but I do not want to show it, just access it. How do I do so without issuing a manual SQL call to the database again?

Bound Text Boxes When Database Value Is Null?

Dec 4, 2009

My application has textboxes that are bound to DataSet fields of a SQl Server 2005 database. The columns in the database allow nulls. The column properties in the DataSet have AllowDBNull set to true. Attempting to write the un-changed data back to the database replaces the NULL values with "", and the update fails on the datetime columns with an error about being unable to convert "" to a date. It appears that the problem is that the null values from the database are being converted into empty strings when the textbox is populated.
