Asked On February 1, 2007 04:48 PM UTC

Can anyone please put an example for creating virtual data grid using collection of objects?

I want the first column to represent the tree view.

There is an example in the samples, but it uses the .cds file that i cannot make changes to.

Thanks,
Adnan

Hi Adnan,

Do you want to use the custom collection in a VirtTreeGrid? If yes, you would have to create and populate a CollapsibleDataSource.data using a code similar to that in CollapsibleDataSource.InitData method. Here is a sample which populates the CollapsibleDataSource.data with a data set. Please refer to the attached sample for more details.

Sample : VirtTreeGrid.zip

Haneef

Hi Haneef,

I have attached the grid example and this is currently bound to a dataset. I have created a Product Object that has a collection of child Products.

The startup page is instantiating a product object. Now i want to bind this product object to the virtual grid.

Also Is there any way to expand columns? For example i have following columns headers:

Week 1 - Week 2 --> They both have + sign next to them. When a user clicks plus the columns expands to days (i.e. show day1, day2, etc).

Thanks for your help.

Hi Adnan,

Question 1: create the collapsible datasource for product object

To display the product object in a virtualtree grid, you neeed to populate a CollapsibleDataSource.data for product object using the below code. Here is a sample which populates the CollapsibleDataSource.data with a prodcute object. Please refer to the attached sample for more details.

Sample : ModifiedTesting2.zip

public void InitFromProduct(Product product)
{
int rows = product.childProducts.Count;
int cols = 0;

this.data = new SampleData[rows + 2];
cols = product.GetType().GetFields().Length;
int ncols = TypeDescriptor.GetProperties(product.childProducts).Count ;

if (cols < ncols)
cols = ncols;

int row = 0;
///For product name datatable.
string[] s = new string[cols];
s[0] = product.ToString();
data[row] = new SampleData(0, TreeNodeState.NoChildren, s);

//product object items...
s = new string[cols];
s[0] = product.ProductName;
s[1] = product.ProductDescription;

row++;
data[row] = new SampleData(1, TreeNodeState.NoChildren, s);

//childproduct item.
foreach (Product item in product.childProducts)
{
row++;
s = new string[cols];
s[0] = item.ProductName;
s[1] = item.ProductDescription;
data[row] = new SampleData(2, TreeNodeState.NoChildren, s);
}

internalColCount = cols;
Locked = false;
internalRowCount = rows;
visibleRows = new ArrayList();
}

Question 2: Is there any way to expand columns?
