Hi,

I use a RadGridView to display my data.
When hovering over the first cell of the first row I show a picture (with Telerik.WinControls.UI.RadOffice2007ScreenTipElement control) by the value of a field in the underlying datasource.
This works fine.

The problem is when I scroll down and I hover again over the first cell of the first row, then I get the same picture (what is wrong because it should be another picture).
I noticed that the ToolTipTextNeeded event doesn't fire anymore for this first row.
When I hover over the first cell of another row (where the ToolTipTextNeeded event has not been fired yet) then it works fine.
So I guess that the ToolTipTextNeeded event only fires if there is not yet a tooltip assigned to that cell.
If that is the case, this is very good because then the picture does not to be rendered all the time but when it's another record that is shown in a row where the tooltip is already set then I would like that the ToolTipTextNeeded fires again
I guess I could do that by setting the GridDataCellElement:Screentip to ? (NULL).
But when can I do that? What event is the best to do this? I tried the scroll-event but it looks like that doesn't fire?
Isn't there some event/property that only fires the first time a particular record from the underlying datasource is shown?

Or I'm i trying to do this in a wrong way?

Remark: isn't there some way to know what events are fired when a form is runned? That way I could try to discover myself what's the best event to do something.

Regards
Didier

I'm trying to add rows automatically and the columns are already created manually in Telerik radgridview, I couldn't add rows dynamically and couldn't make the first row as read only.

 
const int numberOfRows = 5;
    public Form1()
    {
        InitializeComponent();
 
        for (int rowCount = 0; rowCount < numberOfRows; rowCount++)
        {
           radGridView1.Rows.Add();// Problem Here - Index out of range was unhandled
 
            //radGridView1.Rows[0].ReadOnly = true; // problem here
        }
    }

How can i make certain cell alone as read-only in radGridView? Thank you.

How can i make certain cell alone as read-only in radGridView?  I need some help ASAP. Thank you.

I'm uisng Telerik Winforms verison with visual studion 2010 Pro, .net 4 version with original license registered to my company name.

I'm open to any idea besides using a ListView for this.  (I've thought of using a flow layout panel and RadButton as one alternative.)

In my project where we are picking items for customer orders a "License Plate" is a number that uniquely identifies the box that we are using to put the items that we pick for the order.  There are normally three license plates per order and there could be a few more added as we pick.  The user would like to see all of the license plates in a horizontal row (scrolling won't be a problem) and have the person click one of them to assign whatever quantity of an item to that box.  (That is as simple as a button or something that looks like a button with the license plate number for its text.)

So, if a ListView is a good idea here, I'm trying to use one in IconsView mode to take advantage of the horizontal orientation.  I did this so far...

 

I would like to give the items more of the RadButton appearance.  I started experimenting with VisualItemFormatting...

but that hasn't produced a border for me.

If you could first tell me if a different control would be a better choice and, if not, can you help me make the item look like a RadButton (or better, since I suspect that you have better ideas than I would).

 

Thank you,

Gary

 

Hi, 

we are using the TextBoxControl instead of the TextBox because of the performance. Now I need to add a button/Icon in my TextBoxControl. I have found a solution for the Textbox but could not find any solution for the TextBoxControl. 

 

How can i add a simple Button in my TextBoxControl ??

 

Sincerely,

Dominik

I'm using a RadRichTextEditor for WinControls (2017.1.117.40) in my WinForms application and i want to use the RTF text later on in a Stimulsoft Report.

First i import an RTF (created by Winword) from my local machine, it is displayed fine in the TextEditor and in a report designed with Stimulsoft. After i edit the text and try to display it in the report again, the report can't render it anymore as RTF.

I've attached the original text and the changed text as texxtfiles and you can see that there have been put some more tags into the file than in the original.

I'm not using any special propertysettings for the texteditor as far as i know.

So i need the structure as in the Original text, can you help me to figure out what is going wrong here?

Original text:

{\rtf1\ansi\ansicpg1252\deff0\nouicompat\deflang1043\deflangfe1043{\fonttbl{\f0\fswiss\fprq2\fcharset0 Arial;}}
{\colortbl ;\red0\green0\blue0;}
{\*\generator Riched20 6.3.9600}{\*\mmathPr\mnaryLim0\mdispDef1\mwrapIndent1440 }\viewkind4\uc1 
\pard\nowidctlpar\cf1\b\f0\fs20 TESTTEKST\b0\par
}

Changed text after adding "test2" in Texteditor:

{\rtf\ansi\ansicpg1252\uc1\deff0\deflang1033{\fonttbl{\f0 Verdana;}{\f1 Arial;}}
{\colortbl\red0\green0\blue0 ;}
{\*\defchp\ltrch\f0\fs24\i0\b0\strike0\cf0\ulc0\ulnone}

We purchased a software project that had the 2009 controls. We have upgraded the project to use current version of the controls but still have an outdated look and feel. Looking for help and guidance on how to update our app's look and feel to the current Universal Windows Style app.

Hi

 

I want to customise the available filter operators and change the default operator in my RadGridView

 

For example in a string column, I'd like to default to 'Starts With' instead of 'Contains' and want to remove the 'Ends With' operator.

 

Thanks

Tung

I have a Ribbon bar in Outlook view on which I want to change programmatically the font

I have managed to change the font on the bottom buttons with the following code

        outlookElement = TryCast(pvMain.ViewElement, RadPageViewOutlookElement)
        outlookElement.Font = MyPreference.Font

 

However the font of the title does not change (see attached image)

How cant I change the title font as well ?

thanks

Hello guys/girls, how are you?

I hope you can help me.

 

I need to use RadGridView to insert / update / delete data from MySql. VB.NET

I've used this code :

-------------------------------------------------------------------------------------------------

statustestera = Me.RadGridView1.SelectedRows.Item(0).ToString
            statuspantograf = Me.RadGridView1.SelectedRows.Item(1).ToString
            statusdispecer = Me.RadGridView1.SelectedRows.Item(2).ToString
            statusproizvodnja = Me.RadGridView1.SelectedRows.Item(3).ToString
            statusdokumentacija = Me.RadGridView1.SelectedRows.Item(4).ToString

            comm.Connection = cn
            comm.CommandText = "INSERT INTO TBL_Priprema_GROB(StatusTeseta, StatusPantograf, StatusDispecer, StatusProizvodnja, StatusDokumentacija) VALUES('" & statustestera & "','" & statuspantograf & "''" & statusdispecer & "','" & statusproizvodnja & "',' " & statusdokumentacija & "')"
            comm.ExecuteNonQuery()

 

------------------------------------------------

but it returns with the Index can not be negative or less..... error. 

 

Can you please help 

 

 

I was wondering if there is any way to capture a click on MapPin and associate an event handler with that. As far as I could tell, the only element that has events is a RadMap. The MapPin class has a HitTest() method that takes parameters PointG, PointL, and IMapViewport, but even if I were to iterated through all the pins on a map click to see if any of them pass the HitTest(), it's not clear what parameters should be passed in. I feel like there is probably a better way to do it. Can anyone please provide guidance on this?
