Working with (trial) version 2017.2.502.40... 

I'm trying to build a simple editor, but request is that users should be allowed to change only very few formatting details in the document: essentially

- just set bold on / off

- format text as list

- and set paragraph alignment

I've tried to customise the provided ribbon, but if I hide tabs, this results in holes between the remaining tabs.

I've been looking for a sample with a custom toolbar them, but cannot find any.

Any hints

TIA

cannot create an instance of

telerik.wincontrols.ui.gridviewdatacolumn because it is an abstract class

Hi,

I use GridView and custom cell element, however it is wrong to display, please help me to resolve it!

My code and video demo below
+ Change page size -> scroll -> change form size to normal -> hide to task bar -> re-open from task bar -> wrong

+ video: https://youtu.be/8ytr-AFMzRc
+ my code:

Thanks,

Paul.

I cannot get any Events to Fire for radGridView (C#).

Examples:

private void radGridView1_Click(object sender, EventArgs e)
{
MessageBox.Show("Event Fired");
}
void radGridView1_CellValueChanged(object sender, GridViewCellEventArgs e)
{
MessageBox.Show("Event Fired");
}

Is there a missing reference or something?

Please see the attached image. Can someone explain to me how to have the forecolor of the text, currently shown in red, to only display as red if the Source <> Employee?  In the image, only one employees hours / units should be displayed in red (the employee whose source = Third Party).

Apologies to admins for the double posting, but my deadline to complete this requirement is running out.

Can someone please offer some advice?  Surely this scenario has come up before.

Thanks in advance.

I am having trouble removing the blank space between hierarchies / childviews when using the RadVirtualGrid to display hierarchical data.

(see Image01 attached)

If I set 

MasterViewInfo.Padding = new Padding(0);

and

e.ChildViewInfo.Padding = new Padding(0);

the situation improves (see Image02 attached), but I still can't seem to remove all of the spacing between childviews.

Any ideas?

Thanks,

Tom

Hello i wanna ask about this ... 

i have a button with this code 

   Private Sub BtnBaru_Click(sender As System.Object, e As System.EventArgs) Handles BtnBaru.Click

       xStatus = "NEW"

        MCCBRekening.Enabled = True
        Isi_MCCBRekening()

        If MCCBRekening.Text = "" Then
            TxtKodeRekening.Text = ""
            lblNamaRekening.Text = ""
        End If
    End Sub

my question is :

why if i click the button for the second time it's give me error message ... the "Kode" is not belong to TblMstRekening .... 

how i  fix this thanks ... 

Hello!

I was wondering if anyone knew of a simple algorithm to take a bunch of existing Lat/Lon points and calculate a rectangle out of them? I'm trying to have the map view center and zoom to fit a list of points automatically. I know how to center on one particular point but not sure how to do so for a group of points. I'm used to using the Google Maps API which has a function where you can keep adding geo points and it creates a bounding rectangle. Does RadMap have something similar to that?

Thanks! :)
