Re: Arrow keys on form with Tabs with GridViews - C# Discussion Boards

5-Jun-09 1:12

Hi
My form has a few Tabs. Each Tab has a DataGridView on it.

Using the arrow keys switches between tabs. This stops when the user clicks on any cell i a gridview, in which case the arrow keys move around the grid.

Is there any way I can force this mode on entry into a tab?

I have tried setting the top left cell of the gridview to Selected = true, but this doesn't help.

Thanks,
Nigel

Try setting the focus on the tabpage.

How are you managing the tab page change on arrow key press?

You will need to cancel the KeyPress for the GridView and get that code for execution.

I was hoping that there would be an easier solution!!

In other words I must "grab" the arrow-key-presses and make them do what I want them to do, not the default action.

Thanks.

Override ProcessCMDKey method. It will let you do that.

Hello,
How can i declare a string in a loop that the name of the variable will be changed for example according the index of the loop. For example if i will do:
for(i=1;i<5;i++)
string k[i]="something";

it will make me 4 string variables:
k1,k2,k3,k4

I mean the name itself will be changed.
I can't use arrays instead.

You can't, variable names are declared at compile time.
Why you can't use an array?

because i want to use it as adding columns to a datagridview.
And i need it to be in loop because i take those variables from a regkeys i save before.
Can i save antire array as regkey , then read it from the registry and then add it as column names to the datagridview?

Use a dictionay instead.

If what you want to do is set the name of the column, or set its headertext then you can do this in the way you first suggested.

string columnBaseName = // Your method for getting regkey goes here
for (int i = 1; i < 3; i++)
{
    DataGridViewTextboxColumn newColumn = new DataGridViewTextboxColumn();
    newColumn.Name = columnNameBase + i.ToString();
    newColumn.HeaderText = columnNameBase + i.ToString();
    // Set any other properties for the column here
    this.dataGridView1.Columns.Add(newColumn);
}

Hope this helps. Smile | :)

Or a dictionary...

Dictionary<int, string> getString;

for access using the int value, or

Dictionary<string, string> getString;

for access using a name (e.g. "myName"+i.tostring() )

There are three kinds of people in the world - those who can count and those who can't...

there is another ways to do that for example :

System.Collections.ArrayList arr = new System.Collections.ArrayList();
           for (int i = 0; i <= 10; i++)
           {
               arr.Add(i);
           }
           Console.WriteLine(arr[3]);

If it's always the same object type that's being put in the array list and you're using 2.0 or above, then better to use a generic list List<T> where T is the type of the object i.e. List<string>.

ArrayList involves unboxing/boxing which isn't a great idea.
