I want to do something similar (I think) to this:
http://www.telerik.com/help/winforms/listview-custom-items.html

What I want to do is this: I have a RadListView control with 4 columns in a ViewType of DetailsView. The first 3 columns will just display some text in each cell/row, but the 4th cell in each row I want to have a "Remove" button to remove it from the list. So what I need to be able to do is:

Create a Button element to serve as the value for the 4th cell in each row

and

Be able to define and handle the click event for that button (will need some way to identify the row that the button was clicked for as well)

The code I have right now (created based on the example) just displays the button in the first column and none of the text for the first 3 columns seems to get created/inserted.

public class ListViewItemButton : SimpleListViewVisualItem

{

private RadButtonElement buttonElement;

private LightVisualElement contentElement;

private StackLayoutPanel stackLayout;

protected override void CreateChildElements()

{

base.CreateChildElements();

this.stackLayout = new StackLayoutPanel();

this.stackLayout.Orientation = Orientation.Horizontal;

this.stackLayout.EqualChildrenWidth = true;

this.contentElement = new LightVisualElement();

this.contentElement.StretchHorizontally = true;

this.contentElement.MinSize = new Size(60, 0);

this.stackLayout.Children.Add(this.contentElement);

this.buttonElement = new RadButtonElement();

this.buttonElement.Text = "Remove ";

this.stackLayout.Children.Add(this.buttonElement);

this.Children.Add(this.stackLayout);

}

protected override void SynchronizeProperties()

{

base.SynchronizeProperties();

this.Text = "";

this.buttonElement.Text = "Remove ";

}

protected override Type ThemeEffectiveType

{

get

{

return typeof(SimpleListViewVisualItem);

}

and my handler...

private void HandleRadListViewVisualItemCreating(object sender, ListViewVisualItemCreatingEventArgs e)

{

e.VisualItem = new ListViewItemButton();

}

I don't know how to tell it to only make the VisualItem be the button for the 4th column, not all of them.

Thanks,

.RichTextBox1.RichTextBoxElement.BackColor = System.Drawing.Color.Gray;

RichTextBox (obsolete as of Q3 2014 SP1)

Relation does not show

Hello,

I try to create a relation between the MasterTemplate and a ChildTemplate.

The DataSources for the templates have to be filled manually, due they come from different sources (REST and .Net-Remoting).

After fill in the data, I create a relation between them

var relation = new GridViewRelation(_StockGridView.MasterTemplate);

relation.ChildTemplate = _PartsTemplate;

relation.RelationName = "PartToArticleCode";

relation.ParentColumnNames.Add("ID");

relation.ChildColumnNames.Add("ArticleCodeID");

this._StockGridView.Relations.Add(relation);

Unfortunatly... this does not work (anymore!). It worked the first time I created the form etc., but after I've added a control to a container to the form (not to the grid), the gridview refuses to show the hierarchy anymore.

Maybe someone got a clue... I haven't :(

Regards,
Steffen

summary row format and pin

Hi,
i'm trying to make a grid look like the attached image. i want the total part at the bottom to look like the image. i've tried various things and i can't even get it to pin to the bottom.
i found code on another thread that said to do this to get it to the bottom:
grdTxCodes.MasterView.SummaryRows[0].PinPosition = PinnedRowPosition.Bottom;
but that doesn't work for me unless the grid has a bunch of rows in it. when there's no rows or only a couple, the summary row is right under them. I need it at the bottom and also need it to only show for a couple columns. i added summary items for those columns and i do get totals, but all the other columns have what look to be cells under them that are just blank. can those be removed?

i blacked the data in it out for security reasons.

Thanks!

Width of appointments

If you have multiple appointments on one day at one time they appear beside each other.

If you have 3 appointments on 13u00, 2 of these appointments stop at 14u00 and the tird one at 17u00
If you then have another appointment that starts on 14u30 and stops at 15u30 the width of this appointment is 1/3 of the total with for the day. But there is room for this appointment to be 2/3 of the width of that day.

Has somebody an idea about how i can fix this that i can use the fully width of the column?

thx!

Report from generic list?

Before calling my report, I generate a generic list of business objects. The processing is quite complex and I do not want to try to use Telerik's parameter facility to do this.

How can I pass this List<BusinessObject> to Telerik Reporting at runtime? What do I use as a datasource in order to design the report?
