Is it possible to declare namespace and class properties in a custom control? I have a control that loads a dropdownlist which referances a classlibrary that in-turn calls a stored procedure (DataLayer). I would like to make this control dynamic so that I can load differant data into the dropdownlist by setting the properties of the control for the namespace, class and method which will retrieve the data and return a dataset to the control to load the dropdownlist.
I.E.
DataSet ds = New DataSet();
CCNameSpaceProperty.CCClassProperty DataLayerRef = CCNameSpaceProperty.CCClassProperty();
ds = DataLayerRef.CCMethodProperty(ds);

Would a better solution be to pass the dataset as a property into the control to load the dropdownlist?

1: add a field and a button + eventhandler
in the eventhandler do the following:
2: get the data (employee name) out of the field
3: create a sql statement and pass it to the database
4: bind the dataset to the grid
hope this helps
Coulda, woulda, shoulda doesn't matter if you don't.

Create a button named i.e SearchButton and a textfield for holding the employee name.
Create a button_click event handler much like below:
<code>
private void SearchButton_Click(object sender, System.EventArgs e)
{
//Retrieve the name of the employee to search for
string name = this.textBoxName.Text;
//Searchstatement, much like SQL. I.e search for "Name like 'sangeet'".
//You can also add wildcards '%' to catch different versions of your
//searchtext. I.e 'searchstring = 'ColumnNameHere like '%" + name + "%'";
string searchStatement = "Name like '" + name + "'";
//Sort your hits, descending or ascending
string sorting = "Name DESC";
//Search for a row with matching name in column 'Name'
DataRow []rows = this.ds.Tables["TableNameHere"].Select(searchStatement, sorting);
foreach(DataRow row in rows)
{
for(int i=0; i < row.ItemArray.Length; i++)
{
//Do something with the data in each column of your datarow
Console.WriteLine(row.ItemArray[i].ToString());
}
}
}
</code>

Hi all,
Could anyone recommend a good article on how to design ADO.Net in an OOP design in C#? I'm having trouble understanding the subject, as although it's easy to drop data adapters and binders on to a form, this strikes me as being much akin to traditional VB 6 methods of handling data access, and putting lots of logic in the form itself.
Cheers,
Martin.

Create a DAL component (Data Access Layer).
Implement methods like ExecuteSelect, ExecuteInsert and stuff like that  .
this component should handle the connections and other objects .

Hi all!
I am coding an application, which will allow the user to pick a font for their text, in an MS Word fashion (A combobox in the toolstrip). I have managed to create the ToolStripComboBox and populate it with the fonts, but I also want the items in the combobox show their respective fonts, eg Arial would be written in the font Arial.
I think that you must do some custom painting for what I want, but how? If I override the Paint() function it draws everything under the combobox. If anyone could provide me with an example/point me in the right direction I would be grateful!

That's in VB and I'm using C#, could you point me to something which is written in C#?

Hmm... The problem is that that is a regular ComboBox, and mine is a ToolStripComboBox, I think that's the problem. Because when I try to override the DrawItem method it says 'No suitable method found to override', even though I have defined my own.

There doesn't seem to exist a DrawItem event in a ToolStripComboBox. That means that there is no way to do what I want to.

Load them into a Bitmap object and then use the Save method. Yes it is as simple as that.

I don't understand that how to load jpeg code into a bimap object.

Everything you need is inside the Bitmap class.
Look it up on MSDN to see what methods are there for you.

CssClass='<%# (DepartmentID.ToString() == Request.QueryString["DepartmentID"]) ? "DepartmentSelected" : "DepartmentUnselected" %>'>
