The goal of the Telerik Forum is to provide all registered users with a way to find answers to their questions before officially contacting Telerik. In case you need a faster and precise response, please start a new support ticket as it gets higher priority than Forum posts.

A post in the Forums doesn't guarantee you a response from the Telerik support team although 95% of all posts are eventually addressed. Additionally, a post is not assigned a response time as with the support ticketing system.

The Forums can be used to:

• Discuss coding techniques with fellow Telerik users
• Share your experience on the Telerik suite of controls
• Ask general questions, not related to Telerik controls
• Contact Telerik with a question
• Contact Telerik MVPs
• Help other users

Telerik strives to constantly improve its support services but it is essential to have full information to supply precise replies. If we do not have enough details we will not be able to properly address your inquiry and we will ask for further info. The extra loop is sure to slow down the time it takes to resolve your problem, and subsequently the further development of your project.

It is vital that you follow these guidelines in order to receive an accurate response:

I need to format a row depending on a state of the DataBoundItem and i'm trying to use the RowFormatting event.

In some cases i need to set the font of the row to italic and in some other cases i need to hide it from the user.

here is my code

void radGridViewSearchResults_RowFormatting(object sender, RowFormattingEventArgs e)

{

GridViewRowInfo gvri = e.RowElement.RowInfo;

myobject obj = gvri.DataBoundItem as myobject;

if (obj.IsDeleted)

{

gvri.IsVisible = false;

return;

}

if (obj.IsModified || obj.IsNew)

gvri.VisualElement.Font = new Font(gvri.VisualElement.Font.FontFamily, gvri.VisualElement.Font.SizeInPoints, FontStyle.Italic);

if (obj.IsOnError)

gvri.VisualElement.BackColor = Color.Red;

}

The problem is that the rows that should be hidden are still showing up and the ones that should be in red are not?
I've check the state of my objects and they are correct.

I've also remarked that the RowFormatting event is called tice for each item?

What is the correct way of hidding a row from the grid and customize its style?

thanks

Ok I'm only new too this WinForms Gridview so these are probably some simple problems, But thanks in advance for any help you can give.

1) How do I change the default Text in the Group by Row Header.  By default its coming up with <DataField>: <Value>.
Oh and its centered aligned, but I would prefer it left aligned.

2) when I've configured the Gridview to how I Need it, when I run it and try and use the group by feature by drag and dropping a field to the group by header, the new grouped field isn't showing up, up the top in the group by section, so I can't Ungroup  that field.

If anyone can help with these 2 probably that would be greatly appreciated.
Thank you

Hi,
I would like to stop a node expanding while the mouse is hoovering a node while draging another node.

I've tried the following:

On my class which inherits from RadTreeNode:

public override void Expand()
{
// stop node expanding if dropping to it
if (this.TreeView.DraggedNode!=null || (this.TreeView.SelectedNode!=null && this.TreeView.SelectedNode!=this))
return;
...

The problem here is that the node will not expand if it is not selected, which is the case if i click on the expand icon which does not select the node.

private void deviceTree_Expanding(object sender, System.ComponentModel.CancelEventArgs e)
{
// I set the dragNode variable on the Dragging event of the treeview
if (dragNode != null)
e.Cancel = true;
}

The problem with this solution is that the event is triggered after Expand method of the node.

How can I accomplish this? my problem is that many nodes have large quantities of children and the tree is quite sensitive to which node to drop to, one has to move the mouse a little to choose the right node.

root
+ node1
+ node2
+ node3
+ node4

if I want to drop node4 on node2 it requires the user to move the mouse carefully, it could end up on node1,  node2 or node3, but then node1 expands and i have to cancel the drop and start all over again. Is there a way to change this behaviour? that is expand while dropping OR at least increase the "onhoover" time before expanding.

Thanks,
/ jorge

Hello,

Is it possible to change the view of the graph to get a top-bottom view. i.e. Having the origin (0,0) in the top-left corner instead of bottom-left corner of the graph.

Thank you.

Hi Telerik Team,

I encounter that when i am using the RadGridView to do sorting, for example: i am about to sort 1,2,3,4,5,6,7,8,9,10 in descending manner where the datatype is smallint, the grid will return 9,8,7,6,5,4,3,2,1,10 in which i expected 10,9,8,7,6.....,1 since it is smallint datatype.

Pls Help. Thanks

Hi,

I am working with radgrid with winforms 2.0 . I am facing problem to summaries column which i grouped. I wanted to show summary of the group column next to grouped column name.
Does radgrid support this functionlity ? if yes how ?
if No when will i get it ?

Thanks
Nicky

hi guys,
..cheers.. got it. was a different issue which did confuse me..

Just purchased RadControls for Winforms and is starting to use it.

I have a problem with the addnewrow functionality.

Im connected the GridView to a collection of one of my business objects.
It loads just fine. I can edit a value just fine.
I got Allownewrow=true so the "Click here to add new row" shows.
When I enter values here and then change row I can debug that the new object is inserted into my collection, but it does not show any more in GridView. If I do an Update, which saves my collection to DB the object is there and gets saved. If I reload the collection the new row is there.

But I want the user to see new rows added without having to save it. What am I doing wrong?

I face a problem of mingling of words and disappearing of words from listbox. I placed listbox and gridview on same form. Bind them with same data source. I make datagridview editable. Now when I change 2-3 values in gridview the column values showing in listbox become mingl and one two three rows got disappear.

Thanks
Abhisek
