[Solved] dynamic create multiple grids

[Anthony]

I have a project need dynamic create multiple grids based on a value in collection object. I need use Grid_NeedDataSource to bind grid. In Grid_NeedDataSource event I call a method BindGrid(). In OnInit event I have following code:

protected override void OnInit(EventArgs e)

{

Collection categories = GetCategories();

foreach (String category in categories)

{

  DefindGridStructure(category);

}

}

The method DefindGridStructure(category) will create a datagrid based on category value. 

void rgGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

    {

        BindGrid(CategoryKey);

    }

My question is how can I get Category value in rgGrid_NeedDataSource event. I can't use viewstate value since it will be always the last value of the collection.

nobody helps me out? I am still waiting for a solution. Thanks in advance.

Hi Anthony,

You need to save the category value somewhere that will be available in RadGrid's NeedDataSource event. An option would be to save it in the ViewState or Session objects with a unique key for every RadGrid, so that you  have N keys for N categories. Another option would be to somehow include the category value in RadGrid's ID, so that in RadGrid's NeedDataSource event, your (source as RadGrid).ID has the category key included.
