When you create the grid using a loop (for I= 1 to 300, next), as you are placing the values in the recordset you will want to create another object with the same value as the column you are creating and then create an array using the same variable ("I")
In other words, you have columns with apples, oranges, and peaches. The rows have values of the pounds sold per day. To save a value of a particular day to use in another form, etc, you need to create a secondary value for the fruit.
lets say we just use the first letter of the fruit for this variable. When you loop through the grid like this:
dim a(1 to 300) as string
dim o(1 to 300) as string
dim p(1 to 300) as string
recordset.fields.append = Apples, adBSTR
recordset.fields.append = Oranges. adBSTR
recordset.fields.append = Peaches, adBSTR
I=1
for I - 1 to 300
recordset. addnew
recordset("Apples").value= databaseapplenum
a(I)= databaseapplenum
recordset("Oranges").value= databaseorangnum
o(I) = databaseorangnum
recordset("Peaches").value= databasepeachnum
P(I) = databasepeachnum
next
~~~~~~~~~~~~~
so when you want to click on a row and get the value of a frame, you call it like this it like this: (the datagrid starts off at row 0, so you have to always add 1)
OrangeSalesOnDay= o(datagrid.row + 1)
AppleSalesOnDay=a(datagrid.row+1)
PeachSalesOnDay= p(datagrid.row+1)
There may be other ways to do this that are "cleaner" than what I am doing, but this works fine for my needs.
Hope this helps!
You want to use the CurrentCell property of the DataGrid class. It is of type DataGridCell.
This returns the cell that has focus so even if it was not selected(double clicked) it will get returned. So you could do a couple of different things. Add an event handler to your datagrid object for the Double Click event. Or use the IsSelected function of the datagrid class. Whether you need or want to worry about that or not the DataGridCell class has the column and row values of type integer. You can then use the DataGrid.Item function and it will return the value. Example:
dim dGridCell as DataGridCell
dGridCell = dataGrid.CurrentCell
value = dataGrid.Item(dGridCell)
' or you can say
value = dataGrid(dGridCell) ' doesn't matter
I left out a bunch of details but you get the idea.
How can I get a cell value of a particular column on a datagrid and is not the currentcell? I
I want to add the two columns and the sum will be placed on the current cell.
Can anyone help me on this? thanks in advace!!!
My answer here is based on winform application for mobile using C# 2005 programming language...Quote:

Syntax: object variable = datagrid[rowindex, columnindex];
Example, let's say the name of the datagrid control is DataGrid1. And you want to retrieve the value of the 4th cell in the selected row and pass it to a string variable named strVar1. Your code will be like this:
string strVar1 = Convert.ToString(DataGrid1[DataGrid1.CurrentRowIndex, 3]);
Remember that the row and column index is zero-based index. Hence, index for 4th column will be 3.
6 years? A little late on that one I think :)
I think that's okay. There are many other people also want to get similar information, right?Quote:
