Hi,

I have a gridview bound to a datatable with columns defined in the design view and autogenerate columns turned off.
Filtering is enabled on both the gridview and gridviewtemplate yet whenever the filter text is changed no filtering takes place even though the FilterChanged event is firing.
If i remove my defined columns and enable autogenerate the filtering works as expected.
Version is Q3 2009 SP1.

Regards,
Chris

Memory Leak Issue

Hello,

I have posted a message on this issue couple of days back, but it seems deleted from this forum without any update/reply.

We are using Q1 2010, build 308. Found memory leak issue, once forms are loaded and release in RadDock. It was also found that if MDIForm is minimized and again maximized, it release huge memory. Like at the start application took 100,000K and once minimize/maximized, it result in 20,000 K....

We could not understand this behavior and would like to have an update from Telerik experts. How can this be achieved (releasing memory) thru code....

Thanks,
devoas

Hierachical dataset child formatting

Hi,

I have a hierarchical dataset being bound to the gridview and the binding works well. The challenge I am running into is how to format the child gridview (child template). I am formatting the parent row format (hiding columns, setting their widths, etc...) via the grid's DataBindingComplete event handler, but how do I format the children rows format? As an example, I need to hide the first two columns in the child dataset.

Thanks
Ali M.

MORE INFO: I am getting two datasets and binding the grid to them as shown in the code below. I then depend on the DataBindingComplete event handler to control the visibility and size of the columns which works for the master dataset but don't know how to implement that for the child dataset. I would change the formatting logic if this is the wrong way to do it.
Thanks

_adapter = New SqlDataAdapter()

_adapter.SelectCommand = _cmdSelect

_adapter.Fill(Me.dsSync, "Transactions") ', "MBDeviceAuthorization")

_adapter.SelectCommand = _cmdSelect2

_adapter.Fill(Me.dsSync, "Details")

grdTransactionDetails.Tag = "checkouts"

grdTransactionDetails.DataSource = Me.dsSync.Tables("Transactions") ' Me.BindingSource1

Dim template As GridViewTemplate = New GridViewTemplate

template.DataSource = Me.dsSync.Tables("Details")

template.AllowAddNewRow = False

template.AllowEditRow = False

template.AllowDeleteRow = False

template.EnableGrouping = False

grdTransactionDetails.MasterGridViewTemplate.ChildGridViewTemplates.Add(template)

Dim relation As GridViewRelation = New GridViewRelation(grdTransactionDetails.MasterGridViewTemplate)

relation.ChildTemplate = template

relation.RelationName = "CheckoutItems"

relation.ParentColumnNames.Add("rowid")

relation.ChildColumnNames.Add("rowid")

grdTransactionDetails.Relations.Add(relation)

Master / Child Updates

Please point me to (a) sample(s) to distinguish in the insert or update between a master / child the current selection is on.

    
                    private void radGridView1_RowsChanged(object sender, GridViewCollectionChangedEventArgs e)  
        
                    {  

                        case ... I'm changing in the master... // what is the selection
        
                        this.t_FilmTableAdapter.Update(this.pAS2DataSet.T_Film);  

                        case .... I'm changing a child    //how do you select it

                        case .... another child

                        end case
        
                    }

Now, if I have scenes (as a child) and the child template works and I just wanted to update the scene row - where or how do I differentiate that?

Thanks in advance,
Karl

Hierachial Databinding to Entities

Hi,

Does the Winform Telerik Grid Supports displaying hierachial data from object collection.

I can give you a simple example in our application we have a Customer class which has Firstname and Surname and a List of Address details. The Address is a separate class which have properties like Town,Postcode and all

Customer
{
    string FirstName;
    string Surname;
    List<Address> Addresses;
}

the requirement is to display the customer forename and surname only in the main row and the list of address in the child table.

Does the winform grid supports displaying the above scenario?
