C# :: Converting Table To Datagrid?
Mar 30, 2014
i have the following code
protected void Page_Load(object sender, EventArgs e)
{
List<Product> Products = DbConnectivity.LoadProduct();
updateTable(Products);
[Code].....
the code works and produce a table and fills the grid, what im trying to do is get this information into a DataGrid, so i can get rows selected by user. ive tried many ways ie convert the list into a datatable and display but produces errors, ive done the following,
pageLoad....{
FillDataGrid();
DataGridProduct1.DataBind();
}
[Code].....
this populates, but couldnt seperate the SQL connection apart, and it makes no use of the class product

I have been struggling to implement a method for reading data from SQL server to my C# program. In the C# program I prepared a DataGrid (not a DataGridView) for the data to be shown in it using a button "Load Table". Now I just want to read a table which has 4 different columns which I also added to the DataGrid.
I have a DataAccessDB class and this is the code for establishing a connection:
const string DB_CONNECTION = @"It is known to me";
SqlConnection con;
SqlCommand cmd;
Controller myController;
Then, there is a code to reference controller:
public DataAccessDB(Controller refController) {
con = new SqlConnection(DB_CONNECTION);
cmd = new SqlCommand();
cmd.Connection = con;
cmd.CommandType = CommandType.StoredProcedure;
myController = refController;
}
And this is the code for a List which I am going to use for filling the data to a DataGrid:
public List<ProductionStock> GetProductionStockFromDB() {
int productionStockId, amount;
decimal price;
string name, descript;
[code]....
And now the main part - how to read the data when I press a LoadTable button. The point here is that I already defined connection strings here as you can see, and in the method itself I guess I should not repeat it. The tutorials I have seen they do it everything in that one button.

I need to write this program (shown below) for class but i'm not sure how to print out a table?
Write a program to display a centimeters-to-inches conversion table. The smallest and largest numbers of centimeters in the table are input values from the user. Your table should give conversions in 10-centimeter intervals. One centimeter equals 0.3937 inches.
Here is my code so far
Code:
#include <stdio.h>
#include <stdlib.h>
int main() {
[Code].....

I am having an issue with my sort function. This is one part of the Hash table program. The main issue is that I am trying to sort the pointer table after all of the values have been entered. The ptr_sort function is not a class function and so I am therefore unable to use the class variables psize and pTable. Is there another way I should be trying this? it is a Vector should I use the sort() function from the vector class in STL?
#include "/home/onyuksel/courses/340/progs/13f/p9/util9.h"
#include "/home/onyuksel/courses/340/progs/13f/p9/hTable.h"
#ifndef H_TABLE1
#define H_TABLE1
void ptr_sort ( );
[Code] ....

If a user enters a string of boolean algebra it will ouput the table.
I have input parsing, cycling through the combinations, and outputing working. However once i parse the input I am not sure what to do with it. I have thought of having it write the parsed input to a new file as a function and then use that function, but that seems bad.
How to dynamically create the function, how to implement it.
BTW This is a console function, if that changes anything.

I have written an SQL statement that would:
1) Count the number of rows in the table booking that are open and where the booking.postcode is "MK",
2) Take a note of the plot (in booking.plot_id), and then update the table plot.jobs with the value count.
For example running the SQL query when booking table has the following rows:
Would see the following highlighted values in plot.jobs being updated to 1:
I managed to resolve it with this code so far (note I am using Connector/Net):
public void RefreshPlot(){
string query =
"SELECT Count(*) AS count, plot_id FROM booking WHERE postcode='MK' AND status='open' GROUP BY plot_id";
var cmd = new MySqlCommand(query, _connection);
var da = new MySqlDataAdapter(cmd);
var dtCounts = new DataTable();
da.Fill(dtCounts);
[code]....
Currently, my code only checks for existing rows in the booking table and updates the plot table. However if the row gets deleted in the booking, then the changes are not reflected in the plot table.
Example: If we delete the row with plot.id=1 and plot.plot_id=4, then booking.plot_id should go back to being 0, if it was initially 1. At the moment, it doesn't. How would I update my SQL statement to better reflect this? In a sense, it should check for "non-existent" rows, i.e. the impact that the row plot.plot_id=4 & plot.id=1 has on booking.plot_id when deleted?

I am trying to get a datagrid working in my program with populating a simple set of data. Which i can then expand on and bring in data from a database.
But even this little simple test datagrid does not seems to be working.
XAML Code
<DataGrid Grid.Row="6" Grid.Column="0" Grid.ColumnSpan="2" Margin="10" Name="DataGrid_1" ItemsSource="{Binding DataGridData}"></DataGrid>
<Button Grid.Row="6" Grid.Column="2" Margin="10" FontSize="12" Command="{Binding Path=GetDataGridData_Command}">Get Data</Button>

I'm trying to create custom WPF control, similar to DataGrid. DataGrid was great as a base class for a different custom control I needed, because I could do something like this:
<shared:MyDataGrid ItemsSource="{Binding Persons}" >
<DataGrid.Columns>
<DataGridTextColumn Binding="{Binding Name}" Width="4*" />
<DataGridTextColumn Binding="{Binding Phone}" Width="3*" />
<DataGridTextColumn Binding="{Binding Email}" Width="3*" />
</DataGrid.Columns>
</shared:MyDataGrid>
where Person class would be like this:
public class Person
{
public string Name {get; set;}
public string Phone {get; set;}
public string Email {get; set;}
}
... and I can reuse it elsewhere with collections of different type, binding its properties to columns of different width and style.
What I need now is something similar, but differs in a way, that DataGrid is no longer good fit for the base class.
What I'm interested in is: how does DataGrid "tell" the columns in Columns collection, to have the type of ItemsSource bound collection as a DataContext? How does the Name property of Person class become available to the column in DataGrid.Columns?

im trying to populate a datagrid, i have a datbase class
public static List<Product> LoadProduct()
{
....................
}
i have a product class
gettor & settors
public Product(int id, string Name, double Price, int Quantity)
{
productId = id;
productName = Name;
productUnitPrice = Price;
productQuantity = Quantity;
}
ive added the HTML code to set up the datagrid, which i can see via design tab, but filling it up is harder.
i uderstand it needs a
protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1;
sqlDataAdapter1.Fill();// where it require a dataset or datatable
DataGridProduct.DataBind();
as it requires a datatable i converted the list to a datatable when i run it it says null, im not sure where im going wrong, i noe the list works as i tried populating on a table.
public static DataTable ToDataTable<T>(List<T> items)
{

I am a bit stumped with trying to write some code to get the tableadapter/binding source to "update" a current 'user' to the table.
I have the insert/delete methods working fine, but it's the updating that has got me screwed up.
Example of insert.
try
{
personTableAdapter.Insert(tFirstName.Text, tSurname.Text, Convert.ToDateTime(tDoB.Text), tPhone.Text, tAdd1.Text, tAdd2.Text, tSuburb.Text, tState.Text, tPostcode.Text, TeacherType.Text);
teacherTableAdapter.Insert(Convert.ToInt32(tTID1.Text), tRegNo.Text, tPassword.Text);
[Code]....
I also tried to do the updated string/original string with the tableadapter.update, but that didn't work either.

I have a datagrid, which has a column called Status. In the database, the field is a text field that can have the values up, down, or danger.
I needed to display the status as a "light" as per client request, so I have a StatusToImageConverter class that receives the status, and returns the proper image to display in the datagrid column. Works fine.
Now the issue I am having... I have a combo box above the datagrid for the user to filter the results if desired. The filtering works fine, but the newly displayed devices do not have their status light. In the Status column, nothing appears after the user filters. I think it may have to do with the fact that I am not re-initializing the datagrid, but just refreshing it? That's just my educated guess.
XAML:
In the UserControl Resources:
<local:StatusToImageConverter x:Key="ImageConverter" />
In the DataGrid Control:
<DataGridTemplateColumn Header="Status" IsReadOnly="True">
<DataGridTemplateColumn.CellTemplate>
[Code].....

I have the following code in the cellmouse event to get information from a selected row.
private void dt_Grid_CellMouseClick(object sender, DataGridViewCellMouseEventArgs e)
{
datagrid.Rows[0][0] = dt_Grid.Rows[e.RowIndex].Cells[0].Value.ToString();
datagrid.Rows[0][1] = dt_Grid.Rows[e.RowIndex].Cells[1].Value.ToString();
datagrid.Rows[0][2] = dt_Grid.Rows[e.RowIndex].Cells[2].Value.ToString();
[Code]...
but when i select a collumn, i recive an error because i'm selecting a cell with the mouse and i dont have code for that selection. My question is how can i put an "if" on the beguining of the event so that he can determine if it's a header or not.

In my WPF application I created a LINQ to SQL entities class. Then I created a partial class and there add code to my entity class. Below is the code of it:
namespace Mynamespace {
partial class rts_index {
#region Fields
/// <summary>
/// Status:
/// "Selected" - true, "Unselected" - false.
/// </summary>
private bool _is_selected;
[code]....
Then I executed LINQ to SQL. Works perfectly well. Then I bound WPF Datagrid radiobutton column to is_selected property of the partial class. Below is XAML code:
.
.
.
<Window.Resources>
<CollectionViewSource x:Key="rts_indexViewSource" d:DesignSource="{d:DesignInstance my:rts_index, CreateList=True}" />
</Window.Resources>
[code]....
And here I have the problem. When I'm changing the radiobutton status from Unchecked to Checked it doesn't change the value of is_selected property from false to true in the partial class. I don't know why.

I have a problem with this function that adds a new value to the hash table or updates its data if the value already exists:
Code:
int tab_add(tab_disp *td, const object *value) the function should return:
TABDISP_OK if the value is correctly added, or TABDISP_ERROR if memory error, or TABDISP_INVALID if pointer td = NULL
The type of structure I am using is the following:

typedef struct {
char key[25];
char value[100];

int Status::GetEventFromSQL(){
int j = 0;
int eventTime = 0;
MYSQL_ROW myROW;
MYSQL_RES *myRES = NULL;
[code]....
"eventTime " is also declared in another sheet .h as an int. In execution i have a big and negative number ; I know that's because of the int type but i'm bigenner in C++...

I have a table in which data is populated via an element. However some elements can have a parent element
The client now wants all the children and parent elements to be next to each other row wise.
How can i add the child rows under the parent rows?
parents
foreach (var inspection in elemInspections) {
var date = db.INSPEVNT.Find(db.INSPEVNT.INSPKEY == inspection.INSPKEY && db.INSPEVNT.BRKEY == m_sBrKey);
var paircode = db.PON_ELEM_DEFS.Find(db.PON_ELEM_DEFS.ELEM_KEY == inspection.ELEM_KEY);
[Code] .....
how can i make it so the children go under the parent rows?
