Hello
I'm trying to bind a list to a combobow but without effective result
class Rue<br />
{<br />
public int Id;<br />
public string Nom;<br />
};<br />
<br />
List<Rue> Rues = new List<Rue>();
Then I'm trying to fill and bind that list to a Combo
<br />
Rues.Clear();<br />
readRues("1000",Rues);<br />
cmb_rues.DataSource = Rues;<br />
cmb_rues.DisplayMember = Rues[0].Nom;
The Combo displays things but not what I expect
It shows
App.Form+Rue
App.Form+Rue
App.Form+Rue
etc..
Thanks for any help !

I think you need to write:
cmb_rues.DataSource = Rues;<br />
cmb_rues.DisplayMember = "Nom";<br />
cmb_rues.ValueMember = "Id";
|
|

Hello
I've try it too !!
Same result BUT
If I declare the ValueMember I got a message cannot bind to the new displaymember
|
|
|
|
|
Try this:
class Rue<br />
{<br />
public int Id;<br />
public string Nom;<br />
<br />
public override string ToString()<br />
{<br />
return Nom;<br />
}<br />
};

Thank you
It works indeed !
But I really do not understand why and how ?
I'm old to C but new to csharp and oop

The combobox run ToString() for each item.
If you have a class, that does not override the ToString() method, it returns the name of the class- type.
I guess you don't need to run cmb_rues.DisplayMember = ... ??

|

|

I understand better now
Thank you !

Create properties for your members and let the display member be a property. It should work.
Let me know if it doesn't.

Hi,
this is a two-step process:
1. select the text that needs special handling; you can do that interactively, or programmatically; while it already is in place, or while adding.
2. choose a new font for the selected text (RichTextBox.SelectionFont Property) and use
FontStyle.Underline for it.
For all the details, read up on the RichTextBox and Font classes.

Thanks.
Well there's a problem. What if my selection includes multiple fonts? RichTextBox.SelectionFont Property returns null in that case. How can I underline my selection without changing the original fonts?
|

Hi,
if multiple styles are selected, the selection has to be split up into homogeneous
parts; select and underline each part in turn; then restore the original selection.

Thank you. 
Your suggestion worked. I splitted my multi-font-selection into several homogeneous parts, selected each part and underlined them one after another. Finally I restored the original selection.
However, as I try out the program, it flickers.

sure, all Controls basically have that problem, and the more data they hold and the more
operations you perform on them, the more it shows.
Here are some suggestions to reduce the flickering, you pick and choose:
- optimize your code; tha faster it runs the less you will notice it;
- try using SuspendLayout() and ResumeLayout(); I'm not sure how well it helps with an RTB;
- difficult: get the Rtf property, operate on it (that's string operations now, not very
elegant), and when done, store it again
- alternative: have a second RTB, not visible, copy the Rtf from the first to the second,
operate on the second RTB, then copy back the Rtf. This should work nicely.

Im using Visual Studio 2008 language C#.
I have a form with a dataGrid populated from an SQL Stored Procedure, one of the columns on the datagrid it's ButtonColumn and exactly this Buttons HeaderText I would like to use as a parameter for another Stored Procedure.
So if the button is clicked will open a New form with a Datagrid but this time the Datagrid will be populated with a new Stored Procedure which has a parameter and for Parameter value I want to use from the 1st form the ButtonColum Header text.
Is this Possibile?
Thank you

Yes, this is possible, however somewhat tricky.
You have to use the CellContentClick Event on the DataGridViewButtonColumn.

can you a question, i am very hurry!!
I have a database, i want to get a record of table in databases and display this record on textbox and I want to next record or back record, then display this record on textbox again! can someone help me??
|

Hey,
There are several ways to do this, but the most two common ones are pretty easy actually. You can either write a method that does a new query to the database whenever you want a new record, or you can load the data in a datatable ( my personal favorite ) and iterate through each row in the datatable.
The first method is handy, if you have small amounts of data to transfer each time. You make a new connection, get your stuff, and close the connection. If the network you're on is buggy ( assuming you're not running your database locally ) there might be some lag.
That's why I always use the second method. One connection, get the data, stuff it into a datatable and then work from there, assuming it's read-only data.
Cheers,
