Binding Data To DataGridView

Apr 5, 2010

I have a bit of code which loads data from a stored procedure in MS SQL Server and then loads the data to a datagridview, which works fine. What i want is for the code that connects / loads the data to sit in my Database Class and then everything associated with the datagridview to be stored in my Form but i am having problems passing the contents of the bindingsource over to the Form from the Database Class.

Loading XML Data And DataGridView Without Binding

Oct 3, 2010

I have a datagridview (Unbound), which calculate several numbers, and I use this following code to save 5 of the columns to a XML file. My problem is that I would like to load this file back to my datagridview, and onlu to the same columns, without changing the rest of the datagridview.

Code used to create XML file:
Dim gridtable As DataTable = New DataTable("WaypointLeg")
Dim gridtable_collumn1 As DataColumn = New DataColumn("column1")
Dim gridtable_collumn11 As DataColumn = New DataColumn("column11")
Dim gridtable_collumn18 As DataColumn = New DataColumn("column18")
Dim gridtable_collumn19 As DataColumn = New DataColumn("column19")
[Code] .....

How I can load my XML file, and only update certain columns in my datagridview and not add 5 more columns to my datagridview? Is there a way to load the XML data to my datagridview without binding the datagridview to the XML file?

I mean without the use of the:
DataGridView1.DataSource = ds.Tables(0)

How Is WPF Data Binding Using Object Data Source In Visual Studio 2010 Done

Apr 23, 2010

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.

Binding A Datagridview To A Collection?

Apr 4, 2011

I've bound a collection with public properties that are of type double to a datagridview control. If, in the datagrid, the user enters a value that is a string I get an error thrown, and I can't seem to find the method to handle it.

The only way I've been able to fix this is to make all public items in my bound collection of type string, and in the get/set make the private variables double.

This is a huge pain; is there any way to do this in a more elegant fashion?

2nd question is there a way to make the default header text something other than the public property name? (I know I can manually change this in the code later, I was wondering if there was a way to automatically have it something else)

(below is example code; I've changed the P property to reflect that change I had to make)

Public Class clsPIDElement
Private _P As Double
Private _I As Double

Binding A List (Of T) To A DataGridView?

Nov 30, 2011

I have a grid populated from a list. Now there are particular properties in this list that I don't want displayed on the grid. It displays all of the columns perfectly, then adds 2 others I didn't originally have on the grid when I constructed it in designer mode. I have removed them after the binding with DataGridView.Columns.Remove("ColumName"). However, is there a way to prevent it from adding these beforehand, or is this the only way?

Binding Combos In Datagridview?

Jan 13, 2010

I have a datagridview with a column made of comboboxes. Is it possible to bind them to the result of a query? I've been able to do that, but I need to bind each combobox to a different query, or better to the same query which is called with a different parameter.

So, I have column1 which is made of combos. The user selects an item, and in column2, which is made of combos as well, I get some items which are taken from a query where the parameter is the value the user selected in column1. After that, I have column3, made of combos, in which each combo is populated with values resulting from a query with 2 parameters: one is the value selected in column1 and the second from column2. And this should be for each row.

I've been able only to bind the combos of column1, which are all populated using the same query. I thought I could use an array of tables where the i-th element of the array has the table (populated by my query using the table adapter) which contains the element of the combo in row i. Is it possible to bind the combo in column_j and row_i to that table?

DataGridView Binding To DataTable

Sep 28, 2011

I developed a windows forms app, using VisualBasic in VS 2010. In my form, first I declared a variable as DataTable (Dim VarTable as New DataTable).
Second, changed the DataSource property of my DataGridView (DataGridView1.Datasource=VarTable)
Third, I filled the VarTable in this way: using a resulset from SqlDataReader, i added row by row.

Dim Result As SqlDataReader=CommandSQL.ExecuteReader
Do While Result.Read()
Dim RowToAdd As DataRow
RowToAdd=VarTable.NewRow()
RowToAdd("Code")=Result("Code")
RowToAdd("Name")=Result("Name")
VarTable.Rows.Add(RowToAdd)
Loop

Fourth, after the user changed data in datagridview, I saved the data back to SQL, cleared VarTable (VarTable.Rows.Clear()), and back to top of form to accept a new code. But here, problems begin. When I execute again the whole code described, the datagridview dont show the entire rows, and sometimes crashed with different errors. Solution? Dont fill VarTable row by row. Use VarTable.Load(Result) to populate the VarTable. I don't know why now works, But just I wanted to share this information.

Data Binding - Update The Grid Data By Reading The Array

Apr 2, 2012

Data 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?

Binding A Combobox In A Datagridview To A New Table?

Apr 29, 2012

I have set up at DataGridView "cdgvExp" for data entry. cdgvExp.Datasource = ExpTab. The datagridview can accept new rows according to how many entries there are. I will then use the data in ExpTab. The Fourth colum is called "Lot" and is a combobox in the datagridview. The goal is to have the Combobox in the fourth column have the datasource be LotTab which is populated according to other choices in the form. I am hunting for something that would work like an independant combobox like cbLots.datasource = LotsTab

How do I dynamically set the Datasource and Datamember of a combobox that is already set up in a datagridview?

Binding A Single Column To A DataGridView?

Nov 24, 2009

In 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.

DataGridView Add TextBox & And Allow Edit After Binding?

Feb 20, 2012

I have one DataGridView named dgv.dgv is pretty much a plain gridview. No bounded data. No columns added. It's basically empty.I also have one DataTable named dt.I add rows and columns manually into dt.

dt.Columns.Add(New DataColumn("TexBox", GetType(String)))
dr = dt.NewRow()
dr("TextBox") = String.Empty
dt.Rows.Add(dr)

I then simply set dgv datasource into dt.

dgv.DataSource = dt
dgv.Refresh()

I then set the value for this particular cell.

dgv.Item(0,0).Value = "xxx"

Now when I run and execute all those commands. I happen to retrieve the gridview with that value indeed. The "xxx" cell appeared and currently it's uneditable.What I want to achieve is:Allow this "xxx" cell to be editable. Preferrably if it can be inserted into a TextBox control inside the cell.

DataGridView Column Binding Filtering?

Sep 14, 2009

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.
