Hi, my name is Hajun Song from south korea.

I have a radgridview and it has 5 columns and 36 rows
(1 and 2 columns are GridViewTextBoxColumn and
4 and 5 columns are GridViewComboBoxColumn).

I wanna add the images as the combobox's items, so I search and
apply the source base on this example.
http://www.telerik.com/forums/gridviewcomboboxcolumn-that-displays-only-icons-images

When I finished the code and run it, some problems happened.

First, in the first picture,
When the scroll of the table is moved down, some cells not conserned with
image combobox display the images(solid dash line image).
I wanna know how to fix that.

Second, in the second picture, when I open and select the
image of comboBox, some texts are shown as figure.
Although these texts are disappeared if I clicked other place,
but I don't want skip that step. (In upper example source, that has same reaction.)
Can't I fit that? If not, I wanna know how to remove that step.

Third picture is about my source.

Please point out my problem.
And if it is possible, I wanna example source about
successful case of my problems.
Thank you.

WordsProcessing - Value cannot be null.\r\nParameter name: data

Hello, I'm using UI for Winforms on a VSTO outlook plug-ins project. Some Email save to word doc without a problem but some get this error - "Value cannot be null.\r\nParameter name: data".

Here is my code.

var saveAsWord = new SaveAsWord(filePath, _Mail.HTMLBody, _Mail.Subject);
saveAsWord.SaveToWord();

public void SaveToWord()
{
try
{
var provider = new HtmlFormatProvider();
RadFlowDocument document = provider.Import(TextBody);
var providerDocx = new DocxFormatProvider();
using (Stream output = new FileStream(SaveFileTo, FileMode.OpenOrCreate))
{
providerDocx.Export(document, output);
}
}
catch (Exception ex)
{
LogError.LogErrorMessage(ex);
}
}

List View Item to Document window.

I have dragdrop enable on both controls. But i whenever i try to drag an item from the list view over to the document window, it shows the red circle that tells me it cannot drop the object. So i went down the route of implementing PreviewDragDrop to get it working, but then i have no clue how to get the handle of my document window since preview drag and drop is giving me back an RadPageViewTabStripElement and none of the item in there matches a Document window.

Thanks.

Expose more Filter events

Currently the gridview exposes a few events originating from the filter. But I need more. I need to know when the user clicks the filter "textbox" (enter or beginedit) and when the user closes it (leave or endedit). I'm certain internally these events are available, but is there any way to expose them to my code?

Regards,
Martin

How to RadTreeview Text Alignment

Please see my attach screenshot.

As you can see i have 3 nodes and values.
All i want to achieve is to order all 3 values in same position for example:

Destination address: FF:FF:FF:FF:FF:FF
Source address: 00:00:00:00:00:00
Protocol: ARP (0x0806)

My current behavior is:

Destination address: FF:FF:FF:FF:FF:FF
Source address: 00:00:00:00:00:00
Protocol: ARP (0x0806)

How can i do that ?

CellFormatting messes RadGridView up when sorting it

Hello

I'm using CellFormatting event to color some cells in my RadGridView. On Form_Load it works fine (see first image). But when I sort the RadGridView it messes the whole thing up (see second image). You can see my code here:

if (e.Column.Name == "va" && e.CellElement.Value != null)
{
if ((e.CellElement.Value.ToString() == "P" && e.Row.Cells["id"].Value.ToString() == "1") ||
(e.CellElement.Value.ToString() == "A" && e.Row.Cells["id"].Value.ToString() == "1") ||
(e.CellElement.Value.ToString() == "E" && e.Row.Cells["id"].Value.ToString() == "1"))
{
e.CellElement.DrawFill = true;
e.CellElement.BackColor = Color.Red;
e.CellElement.NumberOfColors = 1;
}

else if (e.CellElement.Value.ToString() == "P" || e.CellElement.Value.ToString() == "A" || e.CellElement.Value.ToString() == "E")
{
e.CellElement.DrawFill = true;
e.CellElement.BackColor = Color.Orange;
e.CellElement.NumberOfColors = 1;
}
}

Any suggestions how to fix this?

Thanks in advance

Context Menu with sub menus via designer

Is it possible to create a right click Rad context menu in the designer with submenu items? Or can it only be done in code.

Is there any suitable rad menu that can be created in the designer with sub menus and be used as a right click menu?

Otherwise I can use the standard .Net menu I guess.

Thanks

Gridview combobox datasource

team, i have a rad gridview with two combo boxes, the first combo is prepopulated with categories and the second combo box should populate with the subCategories based on the first combo box for each row. Also when an user changes the first combo box value then the second combo box should update its datasource per row.

Appointment as solid green bar?

Hi,

Is there a way to make an appointment on the calendar appear as a simple solid green bar (rectangle)?

The rectangle needs to start exactly at the event start time and end at the end time and ideally be without any type of fancy shading/background (just a plain rectangle). Ideally, the width of the rectangle would cover the whole width of the cell (assuming no other appointments overlapping the same time period).

Thanks,

-Lou

Manual CRUD

I need to use manual crud in my context.

How do I get the values of the cells in the row being update.

private void radGridView1_CellEndEdit(object sender, Telerik.WinControls.UI.GridViewCellEventArgs e)

{

//TextBox t1 = RadGridView1.MasterGridViewInfo.CurrentRow.Cells("Company").Value.ToString();

//TextBox t2 = RadGridView1.MasterGridViewInfo.CurrentRow.Cells("something").Value.ToString

{

using (var cn = new SqlConnection(connString))

{

cn.Open();

try

{

SqlCommand cmd = new SqlCommand("UPDATE myTable SET Column = @Parm1 WHERE Col = @Parm2", cn);

var parm1 = cmd.CreateParameter("Parm1");

parm1.Value = t1.Text;

var parm2 = cmd.CreateParameter("Parm2");

parm2.Value = t2.text;;

cmd.Parameters.Add(parm1);

cmd.Parameters.Add(parm2);

int rowsAffected = cmd.ExecuteNonQuery();

}

catch (SqlException ex)

{

//MessageBox.Show(ex.StackTrace);

}

1) The first two lines of code above is what I use to implement in radgrid for asp. How do I get those values in this context winforms?
2) I also have added a delete button column. I do I code the event to delete the row where the button is clicked?

Thanks
