VS 2005 Databinding With Labels?
Nov 9, 2009I have a form where I bind the Text property of several labels to various columns in a datatable. A couple of the labels get updated as a result of user selections, so for those labels I set the UpdateMode of the databinding object to 'OnPropertyChanged'. When the user makes their selections, I change the text property of the label - and indeed I can see where the text property changes.
However, when it comes time to save the data, I do a GetChanges on the datatable looking for rows that are Modified - and I get back nothing. I've tried explicitly calling the WriteValue method of the databinding object after I update the text property of the label. Still nothing.

VS 2005 : Stop Combobox Event Firing During Databinding?
Mar 29, 2010I have the following code that populates a combobox:
With Me.ClassSelector
.DataSource = DataAccess.Utilities.ReferenceDataUtils.GetLookupTableData("Category_code_classes")
.DisplayMember = "Category_text"
.ValueMember = "category_class"
End With
However, the SelectedValueChanged event fires once when I set the datasource and again when I set the valuemember. In both instances there is a selected value, although that value was not selected by any user action, but rather because of the loading of the combo box.I don't think there's a 'SurpressEventFiring' property for the combobox, so how to you check to see if the change in the selection was a result of user action and not data loading?Perhaps I'm populating my combobox wrong?
edit: changed 'displaymember' to 'valuemember'

VS 2005 Checkbox Value & Datagrid?
May 16, 2010Interesting problem. I have a datagrid with several columns which are bound to an Access database. Here's the situation...I'm concerned with the 3rd column.This is what I'd like to happen... when the 3rd column(is a checkbox) is checked then column 4(TIME_USER) would be populated with the current time
Basically, this application is meant to keep track of tasks that the user has to do at a certain time of the day. When the user checks the checkbox it would record the time in the database for that task as to when they did it. I found some code from a forum that i changed to fit my needs, but it's not working.

But it doesn't work for some reason. When newPat is true it just saves the XML file as normal but without the extra row.
It seems this code is not working what so ever. I tried replacing
dr("patientName") = gridrow.Cells("patientName").Value
with
dr("patientName") = "test"
And it didn't work, it still saved the names that were in the grid.

VS 2005 Populate DataGrid From Value Of TextBox?
Apr 3, 2009I need some suggestions on how to tackle this issue. I am fairly new to using ADO.NET and am running into difficulty populating a dataGrid.Basically here is what I want to accomplish:
a) on form open the dgvLOCATION populates with any records found in the database that match the customer ID that is displayed in a text box (the textbox will already have a value when the form opens)
b) when the value of the Customer ID textbox changes then the dgvLOCATION will change (I am already going to do this with a text changed event...I am just having problems with the query)
I am using VS Studio 2005 and connecting to an Oracle 10g database.I have also created a 'view' for the dataGrid since it will not any binding.Currently the dataGrid will populate will ALL database records on 'form open' if the field value of Customer ID is not null.
I am using the Query Builder wizard and when I enter the following I get an error.Select C_ID, ST_NUM, ST_NAME, CITY, RESIDENCE From CUSTOMER_LOCATION_VIEW Where C_ID = :TXTCID.TEXT
The error tells me that the query could not be parsed.
