Template Caption in GridView

[Hatsuki]

Hi, everyone.
I am doing Winsform Development based on telerik radcontrol at present.
Specifically, I am building the Hierarchical GridView and setting the template caption for the child template.
However, the Template caption didn't show at all. Do I need set up other properties?

bagTemplate.Caption = "Bag";
if (bagTemplate.Caption != null)
{
    //Popup Bag
    MessageBox.Show(bagTemplate.Caption.ToString());
}

Thank you very much. Appreciate any help!!

Hi Hatsuki,

Thank you for writing.

If your grid contains a single child template, it will not have a corresponding tab and its caption will not be visible. To make its caption appear set the ShowChildViewCaptions of the MasterTemplate to true.

this.radGridView1.MasterTemplate.ShowChildViewCaptions = true;
this.radGridView1.Templates[0].Caption = "Bags";

I hope this helps. Let me know if you have further queries.

Kind regards,

Hello,

I have a grid in hierarchical format i.e.,

> Car
>>>> Parts of car
>>>> Services done with car

Now, to save space on screen, i want to hide certain rows that are not useful. For example group column, add new row , caption etc.

I could hide certain rows at Master template level, but not at child templates. See attached image for more clarity.

For master or parent level, i could achieve using ,
_radGridView.MasterTemplate.MasterViewInfo.SystemRows[0].IsVisible = false

And for child templates, i tried with system rows and even with ,
this._radGridView.MasterTemplate.ShowChildViewCaptions = false;

But, that does not seem to be working.

Hello Divyesh,

Thank you for writing.

When the MasterTemplate has more than one child templates, the ShowChildViewCaptions property does not affect the pageview, displaying the child levels, because the user should be able to switch between the different tabs for example. However, if you use the PageViewMode.ExplorerBar, it is possible to use the ViewCellFormatting event and hide the RadPageViewExplorerBarItem:

public Form1()
{
    InitializeComponent();

    List<Car> cars = new List<Car>();
    List<Part> parts = new List<Part>();
    List<Service> services = new List<Service>();

    for (int i = 0; i < 3; i++)
    {
        cars.Add(new Car(i,"Car" + i));
        for (int j = 0; j < 5; j++)
        {
            parts.Add(new Part(j,"Name" + j,i));

            if (j % 2 == 0)
            {
                services.Add(new Service(j,"ServiceName" + j,i));
            }
        }
    }

    radGridView1.DataSource = cars;
    radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

    GridViewTemplate firstChildtemplate = new GridViewTemplate();
    firstChildtemplate.DataSource = parts;
    radGridView1.MasterTemplate.Templates.Add(firstChildtemplate);
    firstChildtemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

    GridViewRelation relation = new GridViewRelation(radGridView1.MasterTemplate);
    relation.ChildTemplate = firstChildtemplate;
    relation.RelationName = "CarsParts";
    relation.ParentColumnNames.Add("Id");
    relation.ChildColumnNames.Add("CarId");
    radGridView1.Relations.Add(relation);

    GridViewTemplate secondChildtemplate = new GridViewTemplate();
    secondChildtemplate.DataSource = services;
    radGridView1.MasterTemplate.Templates.Add(secondChildtemplate);
    secondChildtemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

    GridViewRelation relation2 = new GridViewRelation(radGridView1.MasterTemplate);
    relation2.ChildTemplate = secondChildtemplate;
    relation2.RelationName = "CarsServices";
    relation2.ParentColumnNames.Add("Id");
    relation2.ChildColumnNames.Add("CarId");
    radGridView1.Relations.Add(relation2);

    this.radGridView1.TableElement.PageViewMode = PageViewMode.ExplorerBar;
}

private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    GridDetailViewCellElement detailCell = e.CellElement as GridDetailViewCellElement;
    if (detailCell != null)
    {
        detailCell.PageViewElement.Header.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

        RadPageViewExplorerBarElement el = detailCell.PageViewElement as RadPageViewExplorerBarElement;
        if (el != null)
        {
            foreach (RadPageViewExplorerBarItem item in el.Items)
            {
                item.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            }
        }
    }
}

public class Car
{
    public int Id { get; set; }

    public string Title { get; set; }

    public Car(int id, string title)
    {
        this.Id = id;
        this.Title = title;
    }
}

public class Part
{
    public int Id { get; set; }

    public string PartName { get; set; }

    public int CarId { get; set; }

    public Part(int id, string name, int carId)
    {
        this.Id = id;
        this.PartName = name;
        this.CarId = carId;
    }
}

public class Service
{
    public int Id { get; set; }

    public string SrviceName { get; set; }

    public int CarId { get; set; }

    public Service(int id, string srviceName, int carId)
    {
        this.Id = id;
        this.SrviceName = srviceName;
        this.CarId = carId;
    }
}

As to the question, related to hiding group area and add new row functionality you can use the following code:

this.radGridView1.EnableGrouping = false;
this.radGridView1.AllowAddNewRow = false;

I hope this information helps. Should you have further questions, I would be glad to help.

Hi Desilava,

Thanks for your response. Based on your suggestion, could hide captions. However, main idea behind hiding caption was to retain that space for actual data. But with suggestion it is still leaving blank space as it is. Any suggestion around that?

See attached file for more clarity.

Hello Divyesh,

Thank you for writing back.

In addition to my previous post, you can set the RadPageViewExplorerBarItem.MaxSize property to new Size(0,5):

private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    GridDetailViewCellElement detailCell = e.CellElement as GridDetailViewCellElement;
    if (detailCell != null)
    {
        detailCell.PageViewElement.Header.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;

        RadPageViewExplorerBarElement el = detailCell.PageViewElement as RadPageViewExplorerBarElement;
        if (el != null)
        {
            foreach (RadPageViewExplorerBarItem item in el.Items)
            {
                item.MaxSize = new Size(0,5);
                item.Visibility = Telerik.WinControls.ElementVisibility.Hidden;
            }
        }
    }
}
