VS 2005 [RESOLVED] biniding data to a datagrid
View 3 Repliesi have an application integrating the an API (autotask web services). I get the data by using a XML query opposed to a SQL query. I'm trying to figure out how to fill a dropdown list with the returned data. Here is my

I am creating a datatable and then adding a column to it which is filled with data from existing column and parsed into correct format DateSold is my existing column from my datafile and I create NewDateSold by adding the column to the existing table and then parsing the information in date format.
This is added to a binding source which then is used to populate a combobox I want to be able to sort the combo box by NewDateSold Desc I was able to this on the original column by simply using the "order By" in my query, it seems now that I added new column it is no longer sorted? I am finding different solution such as using dataview and wish to know the best way to do this
on the custom inherited control i created, i noticed that when i bind my custom property to a data column, if that data column returns a value other than Null it always return a datarowstate of modified even if there were no changes. don't make any changes to the current record before you go to the next record. you will see that the rowstate will still return Modified.
View 8 RepliesI'm trying to add a computed column to a datatable that references another column in the datatable. Sometimes the computed column has a mathematical operation applied to it, but in this case I'm just referencing the original column. The code looks like the following:
ReportData.Columns.Add("1_1_US", _
GetType(Single), _
"1_1")
The code isn't actually hard coded as shown above - there are functions that return the values for the first and third parameters - but I checked those and they are returning the expected values and not generating any errors themselves.
The error is thrown when the .Add method is called, and the error states "Syntax error: Missing operand after '_1' operator." It seems to me that it doesn't like the column name, which I suppose I could change and just workaround it at the presentation level. Still, I'm curious. Is this a bug in the .net framework or something? It doesn't mind "1_1" as a column name in the datatable, so why is it having a problem with it in the expression statement?
I have a DataGridView and one column has DataGridViewCheckBoxColumn type .The datagrid loads from selected items of a listbox.I need to hide Check box cell in this grid according to the item. It means some items should not have checkbox in that cell(I have the list of those items which should not have checkbox in that cell).
View 3 RepliesI would like to make a applcation that after checkbox inside datagridview is checked. After calcuation stuff, if result less than standard, then it set the checkbox to not checked state. But I find that checkbox in datagridview does not change. It changed after I click other checkbox. What I want is lagging one cycle. I tried dgv.refresh() or update event , no effect.
View 2 RepliesIn previous versions (VB.NET 2003) I would do
datagrid.datasource = dataset.tables(0)
datagrid.datamember = "Column1" 'Where this is the name of the column
This would show me just that column in the grid regardless of the number of columns in the dataset.
In VB.NET 2008 I do: datagridview1.datasource = dataset.tables(0)
I see all the columns.I then add:
datagridview1.datamember = "Column1" 'Where Column1 is the column name
I then have an empty grid.How does one get only a single column to show in the grid from a multi-column data source? I am using internal code to populate the datasets and tables.
I have two database tables in SQL Server Express 2008 with the following layouts.
DATA
-------
id
fundKey
amount
fiscalYear
FUNDS
-------
fundKey
fundDescription[code]....
These two tables are related on fiscalYear and fundKey. So if you were to look at the first line in the DATA table you would get:
1,General,2700,2008
I'm trying to create a front-end for this using VB2008. I thought a DataGridView (DGV) would work well for this. So I create a small app to test out my theory. I put a DGV on it and setup a data source to the DATA table using the designer and it works great. Then I change the fundKey column to be databound to the FUNDS column, looking up the fundDescription based on the fundKey. I also change it to a combobox column because in the future I would like other users to easily change the value. And all of this works well.My problem is in that combobox column, all the fund values are listed as options.So it lists: General, Indirect, General, Sponsored. I would like it to list only the values for the appropriate fiscal year. So if that row is for fiscalYear 2008, the fund options should be General and Indirect. And if it's 2009 the options should be General and Sponsored.What is the best way to do this? I thought about setting up views on the SQL Server side and having two datasets in the app and switching between them.
I have a datagridview with a datasource from a MySQL query. Works fine. However, I want to add an extra column and generate some data into the cells. This works fine too and shows up as intended. However, I cannot sort on that extra column and the contents of the cells in the column are cleared out if I sort on the other colums. I realize this is all because of the original datasource, but Im hoping there is a way to "connect" the extra column in somehow?
Grid_SearcherResults.DataSource = dbconnection.bSource
Grid_SearcherResults.Columns.Add("Location", "Location")
'Then some code to set the value of the cells in the new column.. etc

how to use the VS 2010 IDE tools in a way the Microsofties didn't specifically intend. But since this is something I immediately tried without success.
I have defined a .NET 4.0 WPF Application project with a simple class that looks like this:
Public Class Class1
Public Property One As String = "OneString"
Public Property Two As String = "TwoString"
[Code]....
The expected result was that "OneString" would appear next to "One" and "TwoString" next to "Two" in the running window.
The question is: Why didn't this work? What will work instead? If I put bindings in a DataTemplate, it works. Blend, with its sample data stuff, implied that this should work, but it doesn't.

View 7 RepliesData binding should be an extremely simple thing to manage but I can't find a SIMPLE solution to the following problem.
I have two forms
Form1 contains a 4x4 MSFlexGrid (unfortunately an unmanaged COM object but I can merge cells, which I can't do with a managed Datagrid)
Form2 contains other controls which change the data in the Flexgrid.
I connect the two with a Public 4x4 array. Form2 changes the data in this array. I can update the grid data by reading the array. But how do I bind the Grid to the array so that it auto-updates - which is the whole point of binding isn't it?
I have a listbox in my form that gets its values from a data table by data binding. My question is, when the data (row) is loaded it also selects the first line automatically. I do not want this because I want the listbox to select an item only when the user clicks on it. Otherwise, the iteme should ony be listed. Is there a way to manage this?

is there any working examples of implementing add/update/delete using the binding source?
i have a datagridview that has a bindingsource as its datasource and i am wanting to provide Add/Update/Delete functionality on the grid itself. Each record has a delete button which when clicked will remove the row and then add/edit is performed in the grid itself
the user then clicks a save/commit button that will then perform the nessecary updates on all rows
my initial plan was to have a copy of the data (iList) and then compare this to the contents of the binding source data to confirm whether to add/update or delete the record
also upon clicking the delete button i cant get it to remove the row from the datagridview. it thought i could do something like this...
Private Sub dgvDocumentTemplates_CellContentClick(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs)
If (e.ColumnIndex = 6) And (e.RowIndex <> dgvDocumentTemplates.Rows.Count - 1) Then

I have a database that stores images as bytes, per Here
What I want to do is bind the image of a picture box to that value through my binding source. This is what I have:
ProductImagePictureBox.DataBindings.Add("Image", productBindingSource, "productImage", True)
And nothing ever shows up. I figure it's because I am not doing something like Image.FromStream(), but I also don't know how to integrate something like that into that line. I could just re do the image box on row enter rather than bind, but I don't know how to manually pull the data from the binder.
I am trying to get a picture box to update with a new picture when I type in a number in the navigator position item box and hit enter. I have tried various methods, but I can't seem to get a combination that works in this way. Could anyone tell me if what I am trying to achieve is possible, and if so
This is the latest variation I tried (yeah, I know...) :
Private Sub BindingNavigatorPositionItem_KeyUp(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BindingNavigatorPositionItem.ModifiedChanged
Dim Picture As String

I have a bit of code that reaches out and grabs a series of rows from SQL Server DB. I perform an inner join to get some related table data. In the process I get returned the user id of the creator of the data. I then want to pass this into a query to get back a full name. I am having no luck figuring out how to do just that. If I use the data visualizer I can see the name I am after, I cannot figure out the call to extract it
