how can I bind data to DetailTable dynamically.

[Saadettin]

Hi. I have a radgrid. It has DetailsTable in MasterTableView. Iwant to load data to detail tables dynamically, but I can not.
I wrote code like below.

 

grdItemRules.DataSource = rules;
 grdItemRules.DataBind();

foreach (GridDataItem item in grdItemRules.MasterTableView.Items)
{
          GridTableView tableView = (GridTableView)item.ChildItem.NestedTableViews[0];

          tableView.DataSource = rules[item.ItemIndex].RuleItems;
          tableView.DataBind();
}

My code block is like above. Can anyone help me about this? Thanks in advance.

Hi Saadettin,

Please note that using DataBind() is not recommended. Performing complex grid operations such as Inserting, Deleting, Updating, Hierarchy relations, Grouping, Paging, Sorting, Filtering, etc. require accommodating appropriate database operations.  Therefore, we suggest you to avoid Simple Databinding and strongly recommend the use of more advanced databinding methods, which automatically handle the aforementioned functions:
Declarative DataSource
Advanced Data Binding

In your specific case, you will need to use programmatic binding:

In case you want to createyour grid programmatically, please refer to this article:

If you will change the columns structure dynamically, you should implement this approach:

Hope this helps.
